Get off the fence and get to sluicing some gravel Its time to get some Gold

Considering a trommel or a vibrating screen
From Africa, Russia or anywhere in the world,
Our wash plant system can be commissioned now.

Any alluvial gold or Diamond mining project should consider our wash plants. We build and engineer to your property specifications.

Considering a trommel or a vibrating screen?

Saddle up and get to our site in Boise Idaho. The Yanke machine shop can build a robust and reliable plant to get your project on the right path the first time.

I have washed a lot of gold out through the years and we can offer the best in engineering and project evaluation and startup direction.

Applications for the modern placer miners

Applications for the Modern Placer Miner
I am mapping a Diamond exploration pit we dug in Venezuela.

Applications for the modern placer miner 

These basic guidelines I will address in the following months are my experiences in the exploitation of placer mining deposits in many locations around the world.

With respect to Prospecting:
Lets go with the following.

Plan your campaign.  Carefully review your present and historical information and select your prospecting sites. You will need to address a business plan and required personnel. Even a two man prospecting crew needs a budget.

In general , establish disciplined prospecting procedures. I will address this in future posts in detail. Keep detailed records of anything you encounter in you exploration phase.
Topographic maps are 1st on your list, showing among other things, location, surface topography and your surface control lines. Example: 50x50 grid lines.

 Each prospect will dictate your control procedures and cross sections.. These very basic guidelines, I will address in the following months are my experiences in the exploitation of placer mining in many locations around the world.

A good footprint operation. 34 to 45 yph

A Good Foot Print Operation : 35-45 Yards Per Hour
A good midsize mining operation will get you started and really give you some great evaluation, as a paying operating bulk testing program. You will gain invaluable information on whether to size up or down depending what the margins require, within your mining group.   

This is a couple of shots of my signature wash plant. As you can see it is pretty forward and simple.

The plant is light and very mobile on skid mounts. This property I mined, was evaluated and  very deep. This plant was designed for a lesser throughput and higher grade gravel , and this was due to overburden removal requirements.

We had a successful season here. This layout plan worked for this plant and the property .We did not have a lot of big boulders to contend with or tough haul roads.

You can see from the washplant setup that only three men were required to run the operation, everything was kept tight and neat. This type of operation will fit a niche in many of the types of placer operations I run into. It is very easy to size it up or down and add additional rolling stock as your operation requires.

Gold nuggets an the end of the day!!
Gold nuggets an the end of the day!!

This was a good cleanup we had a couple of years ago. What an interesting collection of glacial  
till Gold.

All of the gold in this deposit was on bedrock. We mined about 7 acres and had plenty to smile about.

Gold like this does happen out there. After we  would finish a cut I would go over the cleaned bedrock with a metal detector and never ever found a stray nugget.

Thought I'd share a good gold photo.

Octahedron Gold nugget
Octahedron Gold Nugget

This is a picture of the results of a hard rock quartz ledge seam I discovered in 1988. I was stripping some ground that I was sure was underlaid by an elluvial placer.

An Elluvial placer is the concentration of gold right over where the mother lode vein comes to the surface.

Little erosion had taken place. A bit of old fashioned geological investigation  and I was one of the lucky few on the planet to have found a  high grade hard rock gold vein as good as any that was  found by the first prospectors that  found the rich deposits of gold bearing quartz on Grasshopper creek.

Literally chunks of gold was coming out in the sugar quartz as we mined this section of elluvial property I had on Grasshopper Creek.

That piece of octahedral gold was the largest octahedron nugget of gold I have ever found.
Old Gosta Miller my mentor at the time, absolutely had to have this and I gave it to him for his collection. While I found many smaller specimens this was truly the biggest.

I hope someday his family donates this huge specimen to the Butte school of mines here in Montana as it is one of Montana's true treasures and I discovered it!!!

I donated some smaller pieces of Dendritic and Octahedral gold to the museum and they are currently on display.

Fine gold recovered consistently every mining season

placer mining
Over the many years of placer mining for Gold, we still like using the standard riffle sluice box even for fine gold recovery. As you can see we recover very fine gold from our property here in Montana.

We design industrial wash plants that will fit your alluvial  mining requirements. Not only do we build these wash plants we mine ourselves every season and you can see we consistently get gold every season.

Spelunking, another way to explore geology

Spelunking, another way to explore geology
Copyright Protected, 2016
Rob and Christy are enjoying abundant sunshine and the warm waters in Mexico on a well deserved vacation.  For those of you, like me, who don't know what spelunking is, here is the official definition ....

Caving — also traditionally known as spelunking in the United States and Canada and potholing in the United Kingdom and Ireland — is the recreational pastime of exploring wild (generally non-commercial) cave systems. In contrast, speleology is the scientific study of caves and the cave environment. (Wikipedia).

Short hauls

placer miningWe are short hauling to our wash plant here. Later in the season we hauled our pay gravel up to a half a mile away.

Keeping your bottom line grade control is your objective every day.

We are looking forward to next year!
