West Coast Placer was contracted to conduct high resolution aerial drone mapping of a coal mine in Alberta, Canada. We were hired by the environmental department to map two parts of the coal mine to aid in their reclamation efforts. We produced high resolution imagery and 3D models.
With our fixed wing mapping drone we were able to produce several custom mapping and imagery products. We made a beautiful high resolution orthophoto, a digital surface model (DSM) with topographical accuracy up to 30cm, a LAS format point cloud and one more 3D model. We were also able to format the 3D data so that it could be used in their mine planning software (Minesight).
Two sections of the mine were surveyed. We flew a total of three flights in the same day. The mine asked to have the main pit flown two times to confirm the accuracy and repeatability of the data. We were happy to oblige and of course the flights matched within 2cm of each other. Each section that was flown was about 2 square kilometers and our drone has the flight duration to cover each section in one flight.
The photo quality on the still photos and orthomosaic was outstanding. We were able to achieve an image resolution on the georeferenced mosaic of 4cm/pixel. That means that each pixel in the photo represents a real world footprint of 4cm by 4cm. That kind of resolution cannot be matched by current satellite imagery providers. Actually they are not even in the same league. The best satellite imagery that you can buy today is provided by WorldView-3 satellite and has a resolution of 31cm/pixel. It also costs a lot of money. Google Earth come in at a pitiful 65cm/pixel in the best locations.
Here are some examples of our imagery. First is a shot of the truck that we used as a base station for the drone. You can clearly see the truck, the two operators and even the pickets in the bed of the truck. You can click on these images for a larger view.
Here is a Google Earth image of the exact same location. I love Google and everything that they do but this image is just no comparison. To start with it’s three years old (despite the 2016 copyright note at the bottom), the mine does not even look like that today. The resolution is so poor that you can’t even tell what you’re looking at.
Here are a couple more shots from the same flight. You can clearly see this orange excavator and other details.
The 3D data is also incredible. Check out the video below for a great example of the 3D data that we produced. That video shows a virtual fly though of a LAS point cloud. LAS is the same format that LiDAR data produces.
Drone technology is just making it’s way into the mining world. With the low cost and amazing imagery it is a no brainer for many applications. In the case of this coal mine the environmental team now has excellent data to aid in their reclamation planning that would not have been available only a couple years ago. Check out this post on drone applications in mining.
Our client was very happy with the products that we produced especially for the price. Check out our Drone Services page for details on pricing.
Last week my neighbour phoned me and asked if I wanted to go on a road trip to check out an adit by Harrison Lake. Of course I said yes. Who wouldn’t be down for a short road trip to check out an old mine adit.
The trip only took two hours from my home in Abbotsford, BC. We drove up to Harrison Hot Springs then transitioned to the 4×4 road called Harrison East FSR. Conditions were great for the trip out we got hit by rain on the way back but that’s to be expected on the West coast in March.
I brought along my mountain bike night riding light and it worked awesome! You can see the difference between my super light and a standard headlamp in the video. Check out the video below showing our exploration in the adit:
This adit was created a long time ago, probably a during the period of the Fraser River and Cariboo gold rushes (1860s – 1880s). No records have been found from that time period describing the adit though. During the gold rushes the Harrison was one of the major routes to the Cariboo and many miners worked in the region.
The adit extends for approximately 50m with a slight bend half way in. It cuts through altered schist formations and has several small quarz veins exposed inside. We sampled one of the veins which will be sent to a lab for fire assay. The map below is taken from a 1983 geological report of the area.
In addition to the 50m adit a vertical shaft had also been excavated. Unfortunately the shaft is filled with water so it cannot be explored at this time. Both excavations were carried out to explore a sizable quartz vein. The shaft is right on the 1m wide vein and driven vertically into the bedrock. The adit that we explored was intended to intersect the shaft and the vein. It seems that the miners missed. It is difficult to tell by how much.
Inside the adit there are wooden tracks that line the whole tunnel. These were probably part of an old rail system used to remove the excavated rock. It is not known why the miners abandoned the property, without any information we can only guess. There are other adits in the area that we’ll explore another time. Not bad for a Tuesday afternoon.
In the last couple years the BC government has changed the radio frequencies used on all the forest service roads (FSRs). They used to post the frequencies used so that you could type them in to your handheld radio. With your radio programmed you are able to communicate with other users of the road, ie. logging trucks. The radio system is primarily there as a safety procedure to prevent collisions on BC’s narrow backroads. The cryptic system that they are now using takes away that safety tool if you are not prepared.
I was caught off guard in 2015 when the radio frequency was removed from the West Pavillion FSR which I use to access some of my claims. A sign that mentioned the change was in place but it did not state the new channel.
I found a decent map online that shows which FSRs are using each channel. This map also shows all the FSRs which is cool. You can look around without having to pull out your backroads map book. Here is a link to the map, Chilliwack FSR Map.
This post will help you program your radios for BC’s new RR radio system. You will need a few things for this:
I am using a Baofeng UV-5R programmable radio. I can’t say enough good things about this radio. It is inexpensive (~$30), powerful and has lots of memory channels. The coolest feature is that they are field programmable too. More on the Baofeng UV-5R here, Gear Review: Baofeng Handheld Radio. This guide works for other radios such as a Kenwood or Motorola, although you might need different software.
The cable that I’m using is a FTDI 2-pin Kenwood style. It works for Baofeng and Kenwood radios. For this post I’m using my laptop running Ubuntu linux. But this guide will work with Windows too.
The software is really the key to the whole programming procedure. There is an excellent open source program called CHIRP which stands for CHInese Radio Project. CHIRP was designed to make it easy to program cheap Chinese radios such as the Baofeng, it also works on just about any other radio out there and its free.
OK lets get started. The first thing that we have to do is get a list of frequencies. I found them on a government website, but I’ll save you the trouble and post them right here. You need to download and install CHIRP, on Ubuntu all you have do is run this command:
sudo apt-get install chirp
That will download and install the latest version from Ubuntu’s repositories. If you are running Windows or Mac you can download CHIRP from their website here, CHIRP Site. Installation is easy, just run the .exe file and you’re good to go.
Next start up the program, on linux you need to run it as root (AKA administrator) you can do that with the following command:
OK, now that CHIRP is started you have a few options. You can clone your radio’s existing channels and modify them. You can start a new file or load in an existing one. Lets start one from scratch. Click on the File menu and select “New”. In my example I added a couple extra channels at the top.
It’s a pretty straightforward application. The window functions a lot like a spreadsheet, there is a row for each channel and different parameters are defined in each column. The BC RR channels are pretty basic so you can ignore most of the columns. The RR channels are simplex, that means that they use the same frequency for transmit and receive. Most public channels are simplex. They have no carrier tone or any other funny business. So we just have to enter the frequencies and the name. Leave the rest of the settings at the default values.
After entering all 35 channels you are ready to load them onto the radio. To do that first connect the programming cable to the radio. It plugs into the port where you can add an external microphone. See photo below:
Make sure the radio is turned off when you connect the cable. Otherwise it could shock the memory and wreck the radio. The software will need to know which serial port you have connected to. In linux you can get that information with the following command:
dmesg | grep tty
Look for the line that looks like this:
[147117.481257] usb 2-3: FTDI USB Serial Device converter now attached to ttyUSB0
That is telling us that the programming cable is on port “ttyUSB0”. In Windows the easiest way is to look at your serial ports in the device manager.
Now you can upload the channels to the radio. Turn on the radio with the programming cable attached. Then choose “Upload to radio” from the Radio menu in CHIRP. You’ll be prompted for the serial port, in my case ttyUSB0. You will also need the radio make and model.
Once you hit OK, the upload will begin. You’ll get a nice progress bar to show you how its going.
That’s about it. Make sure that you turn off the radio before you disconnect the programming cable. Now you’re ready to hit the back roads and communicate with other travellers.
Hey guys, I am pleased to announce that West Coast Placer is starting a mining club. There have been a number of inquiries from people who want to prospect and mine on WCP claims. So we’re starting a club that will provide the opportunity for members to use our claims.
Club members will have access to all of West Coast Placer’s claims. Currently that includes 12 placer claims and two mineral claims in BC. Access to some of my partner’s claims is also available. We have claims all over BC including the Tulameen, Similkameen, Fraser River, Cariboo and Kootenays.
Members will be able to work the claims as if they own them. You can run a sluice, pans or whatever you want. Of course members can keep all the gold that they find.
You will be able to camp on the claims in tents or with an RV (where accessible). Family members are automatically included in your membership. Gold panning is a great activity for the whole family, kids love it. You can bring your friends too, the more the merrier.
There are a few obligations that will have to be met.
The first rule of prospecting club is you do not talk about prospecting club. Just kidding I had to throw that in there.
Members must follow all the regulations regarding placer mining in BC. If you don’t know all the regs don’t worry, information will be provided.
Activities will have to be recorded. This will help with our reports to the MTO. It’s not much work, just keep some notes on the work that you do. Keep track of things like, hours spent working, size and location of holes, and take pictures. This information will also be shared with the group.
If you plan on running a sluice or highbanker you will need to have a Free Miner’s Certificate. If you need help getting one, just ask.
There will be an annual fee of $50. Why a fee? That is required to limit club membership to people who are truly interested. $50 is pretty much free compared to similar clubs. The others are looking for $300 and up. We’re not interested in making money off of memberships.
As a member you will also have the opportunity for instruction in the art of gold prospecting. This is great for novice miners. You can join myself and more experienced members on prospecting trips. That is the best way to learn, you can watch youtube videos and read books all day but nothing beats hands on training.
Members will have support from experienced miners. You can even get help with your own MTO reports for your own personal claims. You can ask advice at any time and we’ll try our best to get back to you as soon as possible.
As a member you will be entitled to a discount on the purchase any of West Coast Placer’s claims. There will be more perks as the club grows.
If you are interested please send an email through the WCP contact form on this link, Contact Form. Please share any suggestions or comments that you might have.
Mining under Earth’s oceans is just starting to happen. We have gotten pretty good at mining deposits that are accessible by land but 71% of the Earth’s surface is covered by water. To date no large scale mining operation has succeed under the ocean which means that it’s all virgin ground.
Amazingly the human race has spent more time and money exploring outer space than we have under our own oceans. Over 500 people have been to space while only three have ventured to the deepest part of the ocean, the Mariana Trench. We have better maps of the surface of Mars than the bottom of the ocean, although the ocean maps are pretty cool.
The same geological processes that happen on land also take place under the ocean. There are volcanoes, mountain chains, faults and earthquakes. All the same types of mineral deposits occur under the ocean such as epithermal gold, porphyry, and placer. There are also diamond pipes, massive sulphides and everything else that we mine at the surface.
The ocean also has types of deposits that we can’t find on land. One special mineral deposit is called Polymetallic Nodules. These are concretions of metallic minerals that occur under the ocean. The nodules grow sort of like stalactites do in a cave, over time layers of metallic minerals precipitate out of seawater and add to the nodule. The growth of nodules is one of the slowest known geological processes taking place at a rate of one centimetre over several million years.
Polymetallic nodules are roughly the size and shape of a potato and contain primarily manganese as well as nickel, copper, cobalt and iron. They can be found on the sea floor or buried in the sediment. Nodules can technically occur anywhere in the ocean but seem to be in greatest abundance on the abyssal planes around 5000m deep. Nodule mining would be similar to placer gold mining except under water.
Anouther resource that is unique to the ocean floor is Ferromanganese Crusts. These are similar to nodules but occur as a coating on other rocks. These crusts can be found all over the ocean with thicknesses ranging from 1mm to 26cm. Ferromanganese crusts typically occur in the vicinity of underwater volcanoes called seamounts or near hydrothermal vents. Crusts with mineral grades that are of economic interest are commonly found at depths between 800m and 2500m.
Ferromanganese crusts are composed primarily of iron and manganese, hence the name. Typical concentrations are about 18% iron and 21% manganese. Cobalt, Nickel and Copper occur in significant quantities as well. Rare earth metals such as Tellurium and Yttrium can be found in metallic crusts at much higher concentrations than can be found on the surface. Tellurium is used in solar panels and is quite valuable.
Sea-floor massive sulphides (SMS) are a younger version of volcanic massive sulphides (VMS). The two deposits are similar except that VMS are typically ancient and SMS are currently forming. SMS deposits occur where superheated hydrothermal fluids are expelled into the ocean. They typically form around black smokers near continental rift zones. SMS are know to hold economic concentrations of Gold, Copper, Silver, Lead, Nickel and Zinc.
Black smokers create SMS deposits by expelling superheated sea water that is rich in metallic elements. Cold sea water is forced through the sea floor by the pressure created from the weight of the water column above it. The water is then heated to temperatures in excess of 600°C when it is brought close to the magma that lies below. The heated water becomes acitic and carries with it a high concentration of metals pulled from the surrounding rocks. Once the hot, metal rich, water comes into contact with cold sea water the metals crystallize and deposit on and around the black smoker.
Large scale ocean floor mining has not taken off yet. Attempts have been made since the 1960s and 70s but failed due to technological and financial challenges. Small scale shallow ocean mining has been a lot more succesful in recent years. A great example is the popular TV show Bering Sea Gold. The miners in Nome Alaska are using modified suction dredges to comb the sea floor in shallow waters.
Currently proposed sea floor mining ideas are essentially super high-tech placer mining. They involve ways to dig through the surface layers of the ocean floor, bring the material to the surface and ship it to a processing facility. Its a lot like dredging but on a massive scale. As mentioned above, normal hard rock deposits also occur under the ocean but no plans have been proposed to build open pit mines under the ocean. That would involve all the challenges of building a mine on land with the added complexity of operating under the ocean.
Why is ocean floor mining possible now when it wasn’t 20 years ago? The answer comes down to one word, robots. The world of under water mining is the domain of autonomous drones and human controlled ROVs. Robot submarines are nothing new, they have been around since the 70s and have been used to explore depths of the ocean that are very difficult for humans to get to. UUVs or unmanned underwater vehicles are a little bit newer, they are basically an autonomous version of ROVs. Ocean mining robots have just been invented and share a lot of the technology used in these devices and they look like something straight out of science fiction.
The first deep sea mining project is currently being developed off the coast of Papua New Guinea. The project is called Solwara 1 and is being developed by a Vancouver BC mining company called Nautilus Minerals. Solwara 1 is a copper/gold SMS deposit with estimated copper grades of 7% and gold grades in excess of 20g/t and an average gold grade of 6g/t. The property sits at about 1600m depth.
Nautilus has developed a suite of underwater mining robots and a complete system to mine the precious metal and bring it to shore. There will be the bulk cutter pictured above, an auxiliary and a collection machine. Please take a moment and marvel at these amazing achievements of engineering.
After the robots dig up and collect the ore a custom designed Riser and Lift System (RLS) will bring the material to a giant ship that acts as the mine control center dubbed the Production Support Vessel (PSV). The RLS is basically the world’s most powerful suction dredge. It’s pretty complex, this is the description on the Nautilus Minerals website:
The Riser and Lifting System (RALS) is designed to lift the mineralised material to the Production Support Vessel (PSV) using a Subsea Slurry Lift Pump (SSLP) and a vertical riser system. The seawater/rock is delivered into the SSLP at the base of the riser, where it is pumped to the surface via a gravity tensioned riser suspended from the PSV.
Once aboard the Production Support Vessel the mined slurry will be dewatered and stored until anouther ship comes to take the material on shore for processing. The removed sea water is pumped back down the RALS which adds hydraulic power to the system. Pretty cool stuff! Check out the video below for an visual explanation of how it will all work.
Ocean floor prospecting is not a good place to be gold panning or hiking around with a rock hammer. It is also difficult to take usable photos due to poor light and lots of debris in the water. So how do you explore for minerals in the ocean? Geophysics and robots.
Geophysical exploration is not unique to the ocean. The same techniques are used routinely on land to find every type of mineral deposit. Ocean geophysics is also not new. The main workhorse of mining exploration is magnetometry. Which means mapping changes in earth’s magnetic field using a specialized sensor. The technique was actually developed to detect enemy submarines during World War II. Since then magnetometers and the science behind them have evolved into accurate tools to measure geology.
I’m using a proton precession magnetometer in the photo below. There is some sample magnetometer data on the left. Mag maps look similar to a thermal image except the colour scale represents magnetic field changes (measured in nanoTesla) instead of temperature.
Magnetometers are excellent tools for ocean mining exploration. They are not affected by the water and are excellent at detecting metallic anomalies. There are now underwater drones that can collect ocean magnetometer surveys without the need for human intervention.
Other geophysical techniques have been used in ocean mineral exploration. Electomagnetics (EM) techniques are also great tools for exploration under water. EM works in a similar way to magnetometry except that they emit their own source. Conventional metal detectors are actually a small version of an EM system. While mag passively measures Earth’s magnetic field EM measures the difference between a source and received pulse. EM also works great for discovering metallic anomalies and is being incorporated into autonomous drones as well.
There are other types of ocean geophysics such as seismic refraction which uses a giant air gun to send a sound wave deep into the crust and measures the response on floating hydrophones. Sonar and other forms of bathymetry can provide detailed maps of the ocean floor. Bathymetry techniques can create imagery similar to LiDAR that is used on land.
Ocean mining is just in its infancy and some really cool technology is being used. Advancements in the robotics have allowed mining and exploration to be completed without a person having into enter the water. As technology advances further we will be able to explore vast areas of the ocean floor and discover immense mineral reserves that are presently unknown. It is estimated that we have only explored about 5% of the ocean floor, who knows what we’ll find down there?
In 2015 the number of drone related incidents sky rocketed. Most of the big news stories of this year were about mishaps related to irresponsible drone users.
With the onslaught of amateur drone operators the US government scrambled to pass legislation that would stem the tide of drone crashes, privacy threats and dangerous flying. There was a great fear that massive numbers of drones would be given as Christmas presents this year dubbed by some at the great “drone invasion”.
The FAA took responsibility for making drone users accountable by issuing a new law that all non-commercial drones need to be registered with the agency. The FAA reasoned that drone users are “aviators”
“Make no mistake: Unmanned aircraft enthusiasts are aviators, and with that title comes a great deal of responsibility,” U.S. Transportation Secretary Anthony Foxx said in a statement released by the FAA. “Registration gives us an opportunity to work with these users to operate their unmanned aircraft safely.”
The FAA drone registration website went live on December 21st which can be seen here: FAA Drone Site. Their guidelines are bit foggy and fail to define what is and isn’t a drone. They do have a list of samples though, FAA Sample Guide. The guide seems to suggest that only drones with autopilot capability (aka actual drones and not R/C models) need to be registered. At the moment the registration system is ambiguous and poorly though out.
The knee jerk reaction from the FAA makes an effort to control the huge number of hobby drones taking flight this year. Much like the long gun registration in Canada the people who are going to break the rules will not register their drones anyway.
Transport Canada jumped on the drone invasion bandwagon as well but fortunately did not enact a poorly thought out registration scheme. They launched a media campaign instead to educate users to follow existing regulations (Transport Canada Announcement)
2. Drones interfere with forest fire operations
There were several big news stories this year about drones interfering with forest fire fighting operations in Canada and the United States. This summer was unusually dry and led to an increase in forest fires all over North America. In BC there was a province wide fire ban this summer due to the dry conditions.
One incident near the town of Oliver, BC made headline news across the country (CBC story). Aerial fire suppression crews were hard at work battling a fire that engulfed 1500 hectares and led to the evacuation of over 100 homes. When a small drone was spotted the whole crew of eight helicopters and 6 water bombers was grounded for five hours.
The story spurred negative emotions from many BC residents as the fire fighting effort was desperately needed and the interruption further threatened many homes.
There were several incidents in California this summer too. California had a rough summer with widespread drought and many forest fires. Public reactions were fierce. The county of San Bernadino is offering a $75,000 reward for the identity of drone pilots who interfered with three separate forest fire operations (Reward Story).
3. Hobbyists create weaponized drones
Within the last year two youtube videos from the same drone enthusiast sparked much controversy (CNN Article). In the first video he mounted a handgun to a quadcopter drone and rigged up a remote firing system. The result was pretty intimidating. See the video below.
In December the same enthusiast mounted a custom designed flamethrower to a larger drone and posted anouther video. Once again the controversy spread like wildfire (Popular Science article). The inventor says that the experiments were conducted in a controlled environment with water and fire extinguishers nearby.
Internet users were mostly outraged with many in the drone community lambasting the teenager who created these drone weapons. There were a lot of comments from people fearing their hobby would be banned because of this young man. Others applauded the ingenuity that it took to put these together while some were just plain scared.
It will be interesting to see what hobbyist drone weapons make the news in 2016. Drones were originally developed as weapons systems starting with the German V1 flying bomb in WWII which was essentially a cruise missile. With the long history of weaponized drones we shouldn’t be so surprised when kids are creating them in their backyard.
4. Delivery Drones
Everbody has heard of the Amazon delivery drone by now. News of their plans to develop a 30 minutes or less drone delivery system called Prime Air has been splattered all over the headlines for much of the year (30 minutes or less). Just last month they released a video with former Top Gear presenter Jeremy Clarkson showing a concept of what Prime Air might look like.
Despite the many challenges involved in drone delivery Amazon seems to be taking their plan seriously. They have proposed a special drone delivery only airspace (BBC article). It will be several years at least before the technology and regulations are actually ready for something like this. Take a look at my post on 6 Misconceptions About Drones in 2015 where I explained why this won’t work.
Google (aka Alphabet) and Walmart also filed applications to test drone delivery this year (Walmart Drone Delivery). Futuristic drone delivery remains a tantalizing possibility and will likely remain in the headlines through 2016.
5. Military drone pilots speak out
Military drone strikes were a big story in the news this year. In October a leak was released detailing the United States use of armed drones to murder suspected terrorists and other people they don’t like in the middle east (drone leaks). It had been assumed for years that the US was using drones in countries that it was not supposed to. The leak exposed a massive drone assassination program that was largely unknown
Around the same time stories began to surface of military drone pilots who quit their jobs due to the emotional toll of constantly killing people on the other side of the world (NBC story)
This story from 2012 explains how a US military drone pilot from Montana killed an innocent child. He launched a missile at a building in Afghanistan when a child walked out at the last second before the missile hit. There is a lot of collateral damage in the US drone war campaign. According to this article on Vice News more civilians are killed than suspects (Vice story). Anouther article in the New York Times tells the same story (NY Times).
This summer a man from Louiville, Kentucky took down his neighbour’s drone with a shotgun. He claimed that it was spying on his daughters who were sunbathing in his yard. Initially he was charged by police for discharging a firearm in the city. In October a judge ruled that the drone invaded his privacy and therefore he did not break the law in shooting it (Man Shoots Drone)
The drone’s flight data was analyzed after it was shot down. The drone was clearly above 200 feet and had only been in the air for two minutes. It seems obvious that the shooter was acting emotionally and testified that the drone was closer than it was.
There has a been a lot of hype about drones invading privacy. While camera equipped drones do have the capability to spy on people it is up to the operator to act responsibly. There are existing laws regarding voyeurism and trespassing which apply to drones as much as people.
Of course this was not the only drone shooting incident. A New Jersey man also shot a drone with a shotgun he did not have such a sympathetic judge. He was charged with Possession of a Weapon for an Unlawful Purpose and Criminal Mischief (NJ Drone Shooter).
Anouther interesting drone shooter story took place in Modesto, California (Cal Drone Shooter). Again the shooter acted on concerns over privacy. This case was handled by small claims court when the shooter refused to pay for the parts that he damaged. The drone owner won the court case this time.
In some states its OK to shoot drones in others it is not. It seems that shooting drones is a grey area as in the US the legal system (CNN Drone Shooting).
There have been several news stories of drone incidents on beaches. In one case a man was arrested and charged for throwing his T-shirt into the propellers of a drone causing it to crash (T-shirt drone incident).
A particularly interesting incident happened in 2014 at beach in Connecticut (Woman Assults Drone Pilot). A woman was offended that a drone pilot was flying a camera drone over the beach. She attacked the man and was subsequently charged with assault. The man filmed the assault on his cell phone and she now faces up to a year in prison.
It is not against the law to fly or film in a public space. If you are sunbathing on a public beach people can legally take pictures of you with a drone or otherwise.
7. White house drones
2015 saw two white house drone incidents. The first incident happened in January (NBC, Mashable). The drone operator lost control of his DJI phantom and it landed on the grounds of the white house in Washington, DC. The incident was uneventful other than that fact that it landed on government property. Nobody was hurt, no property damage, etc. Although this story reports that the pilot was “drinking and droning” (DUI Droning).
In contrast the the January incident a man was detained for flying a small drone (Parrot Bebop) at the white house (CNN, DailyMail). The area around the white house was put under lock down. Secret Service agents quickly tackled the suspect and detained him. All the surrounding roads have been cleared of people and cordoned off. The pilot (Ryan MacDonald) was arrested and charged with violating a federal order.
The difference in handling of these two incidents is noteworthy. In one case the perpetrator was a government employee who recklessly went to sleep with a drone in the air, and may have been drunk. He actually crashed his drone. In the second incident the man did not crash and was arrested and charged and the white house was put on lockdown.
8. Drones at airports
Drone incidents at airports have risen sharply in the last year. It is inevitable that with the huge numbers of drone sales a small percentage of owners will operate in a completely reckless manor.
Once incident in May at New York’s LaGuardia Airport involved a near mid air collision between a drone and a jetliner at 2700 feet (Fox News).
According to this article from the Washington post there were in excess of 700 drone related incidents at airports in the United States in 2015 and the article was written in August.
On July 10, the pilot of an Air Force F-15 Strike Eagle said a small drone came within 50 feet of the fighter jet. Two weeks later, the pilot of a Navy T-45 Goshawk flying near Yuma, Ariz., reported that a drone buzzed 100 feet underneath.
There have been some actual mid-air collisons:
On May 9, the pilot of United Airlines Flight 863 — traveling from San Francisco to Sydney — reported that the Boeing 777 hit a drone at an altitude of 3,000 to 4,000 feet along the California coast.
Vancouver, BC has had several incidents as well (CBC News). There was a high profile incident in October at the international airport and one in August involving a sea plane and a quadcopter (National Post). According to the seaplane pilot the drone came within three meters of his windshield when he was landing.
These kind of incidents have been spreading rapidly and in each case you have to wonder what the person was thinking. There are several awareness programs in place now but do you really need someone to tell you that its a stupid idea to fly a drone at an airport?
9. Drones over Paris
In February drones were spotted flying over several Paris landmarks including the Eiffel Tower, and the US embassy. The drones were spotted two nights in a row presumably taking photos or video of the landmarks. Flying a drone at night is illegal in France and drone flights in central Paris are also banned.
The story was huge news despite how little was known. News agencies in Europe reported the facts and that the pilots or drones had not been located (BBC News). Here is an excerpt from a BBC article.
The security threat from these drones is minimal. Bird’s-eye images of Paris landmarks are available online in far higher quality than anything these devices could produce. And small, shop-bought drones are not strong enough to deliver a significant payload of explosives.
News in the United States took the story to a whole different level. The CNN video below has “TERROR IN THE SKIES” as the headline for their report. With no information to go on CNN decided to scare the pants off American viewers.
A week later three Al Jazeera journalists were detained as suspects (Al Jazeera Story). The reporters were in fact operating their own drone as part of their coverage of the mystery drone story. They were detained for 19 hours and questioned.
The actual perpetrators were never found. The Paris drone flights remain a mystery. They were likely tourists using their toy drones to capture aerial video of landmarks.
10. FAA grants over 1000 permits
In August of 2015 the FAA announced that it had issued over 1000 exemptions for commercial drone operation (Fortune Article). Through much of the year they were issuing permits at a rate of 50 per week. The FAA was mandated by congress to come up with commercial drone rules by 2015. They dragged their feet and still only have an interim measure called a section 333 exemption.
Commercial drone activity is illegal in the United States and the permit grants an exemption to the law. The process is similar to what Transport Canada has been doing for a decade. Without a permit there is no commercial work. What this story really means is that the United States is finally able to have a domestic commercial drone service industry. Prior to 2015 only a small number of permits were issued giving the holders a virtual monopoly on drone services. With the increase in permits there is beginning to be some competition in the market.
Section 333 exemptions are not easy to get. There is a paperwork intensive application process and all the criteria need to be met. The FAA is moving towards an actual licencing system instead of the patchwork of regulation that they are now using.

Enrique Iglesias Slices Fingers on Drone
During a concert in Tijuana, Mexico Enrique Iglesias grabbed a drone out of the air and sliced his fingers on the propeller. This story made headlines in May of 2015 (DailyMail Story).
The drone was used to get crowd footage during the concert. Enrique grabbed the drone to get a POV perspective. He continued performing for 30 minutes and was airlifted to a hospital after the show. He was bleeding the whole time. You have to respect the guy for continuing the show despite some fairly serious bleeding.
In part one of the top ten gold rushes of BC we covered the early gold rushes primarily in the Southern regions. As time went on gold hungry adventurers pushed further in the wild North of the Canadian West coast. Their adventurous spirit was rewarded greatly and eventually led them into the Yukon and Alaska.
1865 Big Bend Gold Rush
The Big Bend refers to the shape of the Columbia River as it makes a huge detour at the continental divide. This region encompasses several different mountain ranges including the Selkirks, the Cariboo Mountains, the Monashees and the Rocky Mountains. In 1865 gold was discovered on French Creek which is straight North of Revelstoke. As in other gold rushes a town was quickly erected named French Creek City. Within the first year the town reached a population of over 4000 people. Nothing is left today but during the rush French Creek had a general store, saloons with cabaret shows, barber shops and of course brothels. Other important towns of the rush were La Porte and Downie Creek. The inhabitants came mostly from the Wild Horse area and other areas in BC.
Steamboats were a major factor during the big bend gold rush. Many of the prospectors reached the area on steamboats via the Arrow Lakes which make up part of the Columbia River. The lake network allowed boat passengers to travel from areas as far South as the US border.
Other notable creeks in the area are Carnes Creek, Downie Creek, McCullough Creek, and the Goldstream River. A 14 ounce nugget was reported to be found on French Creek and numerous smaller nuggets were also found. In 1865 miners were bringing out multiple ounces per day to the man on some claims. On McCullough Creek pay streaks averaged 1/8 of an ounce per yard for many years. Just like other places in the late 1800s hydraulic and drift mining driven by mining companies and syndicates quickly replaced hand mining techniques. The big bend gold rush only lasted two years but mining in the area continues to this day. Several large projects and proposed mines are located in the big bend.
1869 Omineca Gold Rush
The Omineca is a huge region in Nortn-Central BC. The southern boundary is marked today by the Yellowhead highway the North boundary is the Liard Mountains. Gold was first discovered in the Omineca in 1861 but the rush didn’t take place until eight years later. The original discoveries were made on the Finlay River. In the early days there were very few people in the area due to a complete lack of trails, roads or maps and unforgiving terrain and weather. Much of the area is still wild today.
One of the first claims on the Finlay called Toy’s Bar produced 4 ounces to the man each day. Several expeditions were launched though the area searching for gold. One such party, the Peace River Prospecting Party, found a great discovery on Vital Creek in 1869. The creek was named after one of the party members, Vital Laforce who was also instrumental in exploring the Cariboo region. Vital Creek produced nearly 5000 ounces in the years following the rush.
Manson Creek and the Germansen River held the best gold deposits in the Omineca. Gold discoveries were also made on Blackjack Creek, Kildare Creek, Mosquito Creek, Slate Creek and Nugget Gulch. In the early days of the gold rush anything less than an ounce a day was considered unworthy. Many creeks were paying 100 ounces per week. If the gold rush happened today that would be well over $100,000 every week. I’d be finding my way up there any any means possible. Travelling to the Omineca in the 1800s was a feat in itself.
The discovery of gold in the Cassiar in 1873 spelled the end of the Omineca gold rush. As with all gold rushes those who held good ground stayed and kept mining while everyone else headed on to the next boom town. The Omineca is one of the least explored regions in BC today and there are still gold strikes waiting to be found.
1873 Cassiar Gold Rush
Gold was discovered on the Stikine River in 1861 and a minor rush developed. A few hundred prospectors ascended the river in search of gold. There was an existing fur trading fort at the mouth of the river called Fort Stikine which later became Wrangell, Alaska. Not enough gold was found to entice more adventurers to the region but the excitement was enough to prompt Britain into claiming the region as a colony in 1862.
The Cassiar gold rush really took off once the high grade gold deposits in the extreme North of BC were discovered. This part of the country is extremely rugged with huge mountains, glaciers and a very cold winter. The discovery was made in the summer of 1872 by Henry Thibert and Angus McCulloch on a creek that drains into Dease Lake. The creek was named after Thibert who froze to death the following winter. Thibert Creek was very rich, in the first year miners were getting up to three ounces to the pan.
In 1874 an even bigger discovery was made further North on Mcdame Creek. The largest gold nugget ever found in BC was taken from Mcdame Creek tipping the scale at 73 ounces! Another giant nugget was found on Alice Shea Creek that weighed 52 ounces.
Several towns sprung up near the gold discoveries such as Laketon, Porter Landing and Centerville. They are all ghost towns now but in the height of the rush thousands of people were passing through the shops and saloons of the Cassiar. Like the Omineca much of this region is just as wild today as it was 150 years ago.
The Cassiar’s rich gold reserves have not been forgotten. There are many large mining projects under way in the region. Due to the high grade mineral deposits the area is known as BC’s “Golden Triange”.
1885 Granite Creek Gold Rush
Granite Creek is a tributary to the Tulameen River. In the gold rush era of the late 1800s the Tulameen was still a remote and wild area. Like many of the best discoveries the Granite Creek gold was found by chance. In this case it was actually found by a cowboy named Johnny Chance. In the summer of 1885 Chance was delivering some horses to New Westminster and took a route through the Tulameen. True to his lazy nature he took a nap at a spot on Granite Creek on a hot day. When he woke up he happened to notice the reflection of some gold nuggets in the water.
Within a year of the discovery the once vacant valley at the mouth of Granite Creek had over 2000 people living there. At the time Granite City was the third largest town in BC. There were over two hundred buildings, 13 of which were saloons. The town never had a school or a mayor though. The bars in Granite ran flat out and never closed down. It was known as one of the wildest towns in the West.
In the early days gold nuggets weighing 5-10 ounces were commonly found. Platinum was also prevalent on the creek. Miners were producing equal weights of platinum and gold. Interestingly for the first few years the Granite Creek miners had no idea what platinum was and most of them threw it back into the creek. At today’s prices gold is going for $1077/oz and platinum is at $870/oz.
The Granite Creek rush brought attention to the surrounding area as well. Other notable creeks in the Tulameen are Slate Creek, Lawless Creek, Lockie Creek and the Tulameen River. Gold and platinum are still being produced today. I heard from a Princeton local that the biggest nuggets to come out of the Tulameen this year were over an ounce. I have some claims on Granite Creek and the Tulameen River myself. Check this post from earlier this year Tulameen Prospecting Trip.
By the end of the 1890s the population of Granite City began to decline. The easy gold was all claimed and in the process of being mined. Those that didn’t already hold good ground headed North to try their luck in the Atlin and Klondike gold rushes that followed.
1898 Atlin Gold Rush
The Atlin gold rush was the last one to take place in BC. It was a direct offshoot of the Klondike gold rush that took the world by storm. The Klondike was the mother of all gold rushes, over 100,000 adventurers poured into Dawson City, YK from all over the world. Some of the adventurous prospectors took a different route and ended up in Atlin.
The first big discovery was on Pine Creek. A town was set up on Pine Creek aptly named Discovery. At it’s peak there were over 10,000 people living in Discovery which was rivalled only by the infamous Dawson City. Discovery had all the excitement of Dawson. There were saloons, brothels, and gambling available at all hours of the day. Discovery is a ghost town today, it was replaced by the town of Atlin.
The gold that was found in the Atlin area was truly legendary. It is estimated that over 1.5 million ounces of placer gold have been produced from the creeks. Some giant nuggets were found too. Several creeks are known to have produced nuggets in excess of 50 ounces! The best placer gold creeks were Pine Creek, Spruce Creek, Ruby Creek, McKee Creek, Birch Creek, Boulder Creek, Otter (Surprise) Creek, and the McDonnel River.
Atlin is a beautiful town, I had the pleasure of working up there a few years ago. In the early 1900s it was nicknamed the “Switzerland of the North” due to the picturesque mountain setting. In many ways Atlin is like Dawson City’s little brother. The music festival is smaller, the gold rush was smaller, less gold was produced but the Klondike is nowhere near as scenic.
Gold mining in Atlin has never stopped. Every time the gold price spikes the area receives another mini gold rush. There are a lot of large hard rock mining prospects in the area as well. The region is not far from the golden triangle and benefits from similar underlying geology. Due to its remote location the area is very under explored and has outstanding potential for exploration.
The BC gold rush period lasted just 50 years. Many of the participants experienced more than one rush in their lifetime. It would have been an amazing time to be a prospector. Here’s a recap of the top ten BC gold rushes:
1851 Haida Gwaii Gold Rush
1858 Fraser River Gold Rush
1858 Rock Creek Gold Rush
1859 Cariboo Gold Rush
1863 Wild Horse River Gold Rush
1864 Leech River Gold Rush
1865 Big Bend Gold Rush
1873 Cassiar Gold Rush
1885 Granite Creek Gold Rush
1898 Atlin Gold Rush
The history of British Columbia is the history of gold and the men who hunt for it. It was the Fraser River gold rush that led to BC becoming a colony and later a province. Our towns, overland trails and roads, and much of the early infrastructure was built to support gold mining activity. Without our lust for precious metal men would not have risked their lives to explore the rugged and unforgiving wilderness of this beautiful province.
Prior to the gold rushes in BC this part of the country remained almost entirely unexplored. The Clovis people and their descendants the North American Indians were the first settlers of North America. The Clovis crossed the Beringia Land Bridge from Siberia to present day Alaska approximately 13,500 years ago. When Europeans began exploring the area, first by sea in the late 1700s and later by canoe, they encountered aboriginal groups covering much of the province. Many Indians had seen gold in creeks but had little use for it. They did not have the knowledge or motivation to mine gold until they came into contact with Europeans. After learning the value of gold to the British they began to mine it and trade for goods.
The Spanish explorers on the other hand were completely obsessed with the yellow metal. Spanish explorers were motivated primarily by legends of “El Dorado” in their search of the Americas. Each Spanish explorer had the ultimate goal of returning to Spain with a ship full of gold. Most of their attention was focussed in South America where their superior weaponry, armour and small pox allowed them to quickly decimate tribal empires and steal their gold. There is evidence of Spanish gold exploration in BC as well. Most of the Spanish exploration took place on Vancouver Island and other coastal areas such as Haida Gwaii. One Spanish expedition travelled inland as far as the Okanagan and Similkameen regions.
Fur trading is what led to the first European settlement of British Colombia but the impact remained relatively small. The first settlements were established by early explorers such as Simon Fraser, Alexander Mackenzie, and David Thompson. Early forts were established along the river routes that these explorers used as well as along the coast. The area became a recognized fur trading district called New Caledonia and it held that name until it became a British Colony in 1858.
Fort St. James was founded in 1806 and was the first major inland fur trading post in BC and still bears that name. Other notable early forts are Ft. George (now Prince George), Ft. Kamloops, Ft. Langley and Ft. Victoria (1844). During the fur trade the European population slowly grew to a few hundred people but little effort was put into exploring new ground outside of the established trade routes.
1851 Haida Gwaii Gold Rush
The Haida Gwaii gold rush was the first recorded gold rush in BC but was very short lived due to hostilities with the local natives. The rush began in 1851 when a Haida man traded a 27 ounce nugget for 1500 blankets in Fort Victoria. A Hudson’s Bay Company ship was sent up there soon after and discovered a very high grade lode deposit.
The HBC crew began mining the lode deposit but the Haida Indians soon turned against them and prevented further mining. In 1852 a ship with 35 adventurers from San Francisco set out for the islands. They arrived at “Gold Harbour” in the Tasu Sound but did not have much luck finding gold. They did however manage to trade with the Haida Indians for gold.
1857 Gold Found At the Nicoamen River
Placer gold was discovered in Nicoamen River which is a tributary to the Thompson River. The Nicoamen enters the Thompson about 12 kilometers up stream from the confluence with the Fraser River at Lytton. A local Indian discovered gold there by chance and soon the majority of the tribe was mining the area. This discovery is credited with igniting the Fraser River gold rush.
1858 Fraser River Gold Rush
The Fraser River gold rush involved one of the largest populations of migrant prospectors in history. It is estimated that around 30,000 people rushed to the lower Fraser River in 1858. The rush began after an 800 ounce gold sample was sent from Fort Victoria to San Francisco for assay.
Soon after a shipload of 800 American prospectors from California arrived in Victoria to hunt for gold on the Fraser River. The influx of American prospectors overwhelmed the small government that managed the territory. HBC Governor James Douglas requested immediate help from Britain to control this massive foreign population . The British Government responded by formally claiming BC as sovereign British Colony in 1858. The new government quickly enacted mining laws to prevent the mayhem that took place in the California goldfields. Along with the declaration came British military support and the Royal Engineers who went on to build several major road systems including the Cariboo Wagon road and Dewdney Trail.
The early work centred around the community of Hope where steamboats allowed for easy access. The majority of the gold rushers were participants in the California gold rush that fizzled out a few years earlier. As a result the population of Yale was largely american and the town was modelled after San Francisco.
A story in the San Francisco Bulletin is credited with igniting the rush. According to the newspaper:
“In one month the Hudson’s Bay Company fort in Victoria had received 110 pounds of gold dust from the Indians … (prospected) without aid of anything more than … pans and willow baskets.”
Numerous bars were prospected and mined between Hope and Lytton. Some communities along the Fraser are still named after the bars that were mined such as “Boston Bar”. Like most gold rushes the men who arrived first snapped up the good claims and the the majority of the adventurers ended up working for them.
The British Royal engineers developed a route from Port Douglas at the head of Harrison Lake to Lillooet to accommodate the influx of miners. Many new communities popped up and some are still settled today.
The Fraser rush brought people from all over the world but the bulk of the miners came from California. At the peak of the rush there were over 10,000 miners operating on the section of river form Hope to Lillooet. The bars depleted rapidly and by 1860 most of the miners continued on the other gold rushes in BC.
1858 Rock Creek Gold Rush
Gold was discovered in Rock Creek in 1858 soon after miners rushed in from the United States and the rest of the world. The Rock Creek rush was also instrumental in the development of British Columbia. The discovery was made by two American soldiers who were chased North of the boarder by a band of Indians. Just 5km from the border where an unnammed creek entered the Kettle River they found gold.
At the time of the discovery the colony of British Columbia was only a year old. American miners tried to claim the area as part of the United States due to the high grades and the fact that it was discovered by Americans. The Rock Creek claim issues prompted the construction of the Dewdney Trail as a means to separate the new colony from the United States. The Dewdney Trail snaked its way from New Westminster all the way to Wild Horse in the Kootenay region staying just North of the Canada-US border.
Soon after the discovery an estimated 5,000 prospectors migrated to the newly established town of Rock Creek. In the beginning there were two saloons, a butcher’s shop, a hotel and five stores. Within the first year a revolt broke out due to tensions between Chinese and American miners and refusal to pay for mining licences. The incident became known as the Rock Creek War. The governor of British Columbia Sir James Douglas travelled there from Victoria to straighten out the miners. He threatened to send in 500 British soldiers if they couldn’t behave themselves. Sir Douglas was successful and soon the miners paid their claim fees and mined the creeks in peace.
There were some amazing claims on Rock Creek. Adam Beame’s claim on Soldier’s Bar in 1859 allegedly netted $1,000 in six weeks. That gold would be worth $70,500 today! Other bars such as Denver Bar and White’s Bar produced similar results.
1859 Cariboo Gold Rush
Gold was discovered on the Horsefly River in 1859 by prospectors who participated in the Fraser River rush. They were guided by a local Indian and shown a spot on the Horsefly River with abundant gold and nuggets the size of wheat kernels. The rush was on as more miners from the Fraser River rush migrated North to the Cariboo. Soon a town was erected near the strike that exists today.
In 1860 gold was discovered on Keithly and Antler creeks to the North of Horsefly. Other notable creeks of the region are Lightning, Lowhee, and Williams Creeks, the Quesnel River and Parsnip River. Towns popped up all over the place with the most exciting being Barkerville. That town was named after a British prospector named Billy Barker and had a popluaton of 10,000 at its peak. His claim on Willams Creek was one of the greatest gold producers in history yielding an estimated 37,500 ounces of gold. Barkerville was restored in 1997 as a tourist historic town that is a popular attraction in the area.
The Cariboo gold rush saw 100,000 people flood into the area during 1862-70 from all over the world. By 1864 the Cariboo Wagon Road was completed from New Westminster all the way to Barkerville. This allowed for easy travel of people and supplies, wich substantially brought down the costs. It also allowed for stage coaches to securely move gold from the mines. The stagecoaches operated on this road from 1863 to 1917 carrying people, mail, express packages and of course gold. The stagecoaches saw surprisingly few hold ups, even though they carried literally tons of gold. There are only five hold ups on record, two of which were successful.
By 1870 the gold rush had largely fizzled out. The good claims were now owned by mining companies who could gather the money needed to undertake underground drift mining. Those who didn’t stick around to work in underground mines spread around other parts of BC’s North and some sparked gold rushes in new areas. Others settled in and started up cattle ranches or logging companies. Gold mining in the Cariboo is still active today, as a matter of fact I have a couple claims near Keithly Creek.
1863 Wild Horse River Gold Rush
Gold was discovered on the Wild Horse River in the Kootenay region in 1863 once again by American prospectors. The Wild Horse held great gold reserves and still does today. Early in the rush huge nuggets were found with the biggest tipping the scale at 36 ounces. The first town that was built was called Fisherville. Apparently after one resident found a nugget under his house the size of his fist the whole town burned their houses down to dig underneath.
A town was erected named Galbraith’s Ferry, named after John Galbraith who operated a ferry across Kootenay lake. Later the town was re-named Fort Steele after the legendary Sam Steele. A second gold rush broke out in the same area in 1885. Later hard rock silver rushes spread around the region.
The Wild Horse River is estimated to have produced over $7,000,000 in the initial gold rush which would be worth about $490,000,000 today. There is a very well preserved historic town at Fort Steel that is a popular tourist spot with many actors playing the roles of old time blacksmiths, prospectors, sheriffs and so on. It is located North of Cranbrook at the intersection between Highway 93 and 95.
The initial gold rush ended after about 6 years but soon the great silver rush would flood the region. Places like Nelson, Kaslo, Slocan grew out of the silver rushes that blanketed the Kootenay region.
1864 Leech River Gold Rush
The Leech River gold rush started with a letter from Robert Brown who was Commander of the Vancouver Island Exploring Expedition. Yes that was the correct name of the VIEE expedition. The expedition was launched by the British government in Victoria.
A letter from Brown published in the British Colonist newspaper on July 29, 1864 ignited the rush. Here are some exerpts from the letter:
..the intelligence I have to communicate is of too important a nature to bear delay in forwarding to you, even for one hour…
The discovery which I have to communicate is the finding of gold on the banks of one of the Forks of the Sooke River, about 12 miles from the sea in a straight line, and in a locality never hitherto reached by white men, in all probability never even by natives. I forward anquarter eighth of an ounce (or thereabouts) of the coarse scale gold, washed out of twelve pans of dirt, in many places 20 feet above the river, and with no tools but a shovel and a gold pan. The lowest prospect obtained was 3 cents to the pan, the highest $1 to the pan, and work like that with a rocker would yield what pay you can better calculate than I can, and the development of which, with what results to the Colony you may imagine.
A town called Leechtown was built near the discovery. By November that year there were an estimated 6 general stores, 3 hotels and over 1,200 miners at work in the area. By 1866 an estimated 200,000 ounces of gold had been produced in the area and the gold rush had passed its peak. It was over in a flash as the Leech and Sooke river placer deposits, although high grade, were limited in size.
In the span of one decade gold rushes turned the vast unexplored fur trading district of New Caledonia into a sovereign British Colony. By the end of the 1860’s the new region had gone from a population of under one thousand people to a colony with several major wagon roads and towns covering much of the Southern half of BC. The gold rushes continued and led to more development in British Columbia. Stay tuned for part 2.
This claim is located in the Cariboo-Chilcotin region of BC. The location is fairly remote and there are no paved roads for quite a distance in any direction. When you are out there you are definitely alone. It has sort of an eerie feeling all day and night, it feels deserted. There is a ghost town near the claim and some signs of a more active human presence from a distant time. Check out this post for pics on of the ghost town, Southern Cariboo Prospecting Trip.
The hike down to the river is pretty tough. There is about a 1000 foot elevation change from the access road to the river. We went down there the first day to sample the beach. We came across a couple of bedrock outcrops which prevented us from travelling any further. The bedrock had some gold stored in the cracks and we were able to get some of it out. Near the river we saw some decent colour in our test pans. We marked the locations on my GPS and made our way back up to the camp.
We had some great burgers cooked on the campfire and a couple of beers. It is getting pretty cold up there this time of year. Once the sun goes down the temperature quickly falls below freezing. We had a nice big fire and enjoyed the stars for the evening. It was pretty tough to get out of our tents in the morning. The moment when you unzip your sleeping bag and start putting on cold clothing is the worst. I’d like to stay in my nice warm bag for a couple more hours but we came up here for a reason.
We found an old claim post with tags from 1989/90 right in the center of the claim. The post was actually carved out of a tree trunk and is the most creative claim post I have ever seen. As far as industrial markers go this is a work of art. I hope to find out more about this G. Johnson and what he had discovered on the claim.
As we were making our way down to the river for day two of prospecting we came across a creek that seemed to appear out of nowhere. My partner noticed some gravel near the surface and we thought we might as well pan it. In that pan we saw a small coarse chunk of gold. This was pretty exciting since it was located several hundred feet above the river. We took several more pans in that spot and found a little bit of gold in each one. Now we have to find out where that mysterious little creek is getting the gold from.
My partner had a Bazooka Gold Trap and we tried it out on this little creek. The gold trap seemed to work pretty well. It’s an interesting design that has a chamber at the back and a water scoop underneath that forces water into the trap.
That was our last trip of the season to this area. The weather forecast says snow is coming this week and it will probably stick until the spring.
Placer mining and exploration breeds innovation like no other activity. Virtually every prospector that you talk to has their own idea of what the best tool, product or technique is. If you ask three different miners what the best sluice is you’ll get three different answers. Much of the innovation comes from the trial and error learning process of placer mining. What works at one claim might not work at the next. You just have to experiment until everything works the way you want it to.
The history of placer mining has a long list of innovations and miners benefited with increased yields at each step along the way. The gold pan was one of the first inventions, then followed the rocker box, sluice, variations of the sluice such as the long tom, hydraulicking water jets, dragline dredges and so on. The miners in the Klondike gold rush learned to melt the permafrost using fires to reach the bedrock below. Now they use modern excavators and bulldozers but it had to start somewhere.
Every inventor claims that their product is the best. It can be hard to distinguish the good from the not so good. In the case of the Pyramid Pro pan developed by Dennis Katz at Fossickers.com it is a game changer. I am not affiliated in any way with the manufacturer of this pan I just really appreciate the technology. Fossicker is an unusual word, according to their website it is the Australian word for gold prospector.
There are other pyramid shaped pans on the market but this one has some very unique features. First off it has insane riffles! These riffles do two things. They break up clay or hardpack along with the violent action of the pyramid panning motion. And they prevent any dense material (ie.gold) from escaping. The violent action must be emphasized. In conventional gold panning you want to avoid too much force and splashing because you will force your gold right out of your pan but that is the essence of the Pyramid Pro. The action is hard to describe and best seen in person. Check out the developer’s own instruction video below to see how it works.
It is a little funny how the Fossicker keeps saying to “stratisfy” the material. What he really means is stratify, maybe its an Australian thing too. You hold the pan with those big handles almost like you’re holding a gas powered ice auger. It is a bit of an arm workout when you are going through a lot of material but the Pyramid Pro is designed to do exactly that. The experience is very unique and has little to do with conventional gold panning. The Fossicker calls the neck of the pan a pre-mix chamber. Once you get the technique down nothing will escape that chamber.
The most important benefit for prospectors is that this pan is a lightweight unit that can concentrate a lot of material. It can essentially replace a small sluice or highbanker for a similar amount of material. Where it pays off the most is in places where you need to hike in to access a claim. You are not going to hike with a trash pump, sluice and hose for any considerable distance. With the Pyramid Pro there is no need to. I’m not saying its going to replace a highbanker or dredge when it comes to production. Technically it could but you would need forearms like Popeye.
Where this pan really shines is in volumetric sampling. That means taking a sample of a set volume and using the gold values to estimate the pay over a larger area. For example you can take a sample of 50 liters of raw gravel. Concentrate it with the pyramid pan and then separate and dry your gold. You can then weigh that gold and extrapolate that number to a cubic meter or yard. As an example if you had 0.025 grams of gold recovered from your 50L sample that would equal 25g per cubic meter or almost an ounce. With careful sampling you can be confident that the area is worth the time and money to mine it.
The pressure plug at the bottom makes taking samples super easy. Once you have concentrated your sample down, you just pull the plug and dump it into a container. If you were doing the same thing with a highbanker you would have to do a full clean up for each location. With this tool you can rapidly sample a large area in no time flat. The plug can be easily replaced if you damage or lose it. The plug is just a 1.5″ plumbing plug which is available at any hardware store.
The plastic is surprisingly tough. I had my pyramid pan on the back of my pack on a particularly perilous prospecting mission. I wiped out on a jagged rock outcrop and landed with my full weight on the pan. I thought it was going to be toast but was relieved to see that no damage at all had occurred. Likewise with my other plastic pans. I don’t know what kind of plastic they use but it is unbelievably durable. The Fossickers website claims that it has a lifetime guarantee just in case you did manage to break it.
The Pyramid Pro pan is the center of my sampling technique. The fact that it is ultra-portable and can concentrate a lot of material makes it an indispensable tool for the modern prospector. They are not cheap though, I paid $120 for mine and its worth every penny.
