Mineral Handler Tray: new sizes and new inventory

Mineral Handler Tray: new sizes and new inventory
Just had my buddy make up a bunch of these easy mineral handler trays.

These trays make handling your  Gold, Sapphires or Diamonds very efficient. I have used these for may years and strongly advise any mining venture, to have 5 or 6 of these in your cleanup room.

They are made of stainless steel and make gold concentrate cleanup with a magnet, a snap.

I have been using these for over thirty years and I just love them.

We offer them on our website. Gold dredgers, the weekend prospector or alluvial commercial operations, will benefit from these trays. Spring breakup is just around the corner!!

The last day of the 2014 Montana Gold Mining season!

Montana Gold Mining
My brother Les my best friend and unbelievable Mining partner are giving it a good shake.

We had a good year of placer mining and we are congratulating each other after we shut down the water pump on our last day.

We are looking forward to another year and I have been busy with next years mining plan. Next year we will be working old unworked pockets near some old hydraulic workings.

Mine site reclamation on our Montana Placer Gold mining project.

Mine site reclamation
This is a snapshot of our Gold mining project here in Montana this year.

We have a strong emphasis on reclamation.  This is a photo of our reclamation of the previously mined out area of our mine site.

We have exhausted this lower part of the meadow but have some more promising targets on this property.

We will have two or thee weeks of reclamation this spring before we start mining again.

I am walking along a reseeded portion of our mined out site and I am very pleased with the revegitation that has taken place.

Nitty Gritty of Placer Gold Mining: just like technology it's an ever evolving process

placer mining methodsPlacer Mining Methods

We encountered some limestone bedrock that would not yield, even with our 345 excavator.

A substantial amount of values were still in these natural riffles we encountered.  You can see the bedrock very clearly here and how it show's nature doing its best to concentrate the gold.

Its a nice example of a sedimentary process and response.  This depositional setting and bedrock change, for the short term  really helped our bottom line at the end of the day.

We brought in a large compressor and did the final sweep of the hardest part of the bedrock and
noticed a spike in the recovered values that day.

As we advanced further, the bedrock was softer and we were back on our normal recovery values.

You alway's try to recognize changes as you encounter them and adjust your materials handling to the new challenge! Gold placer mining is an ever evolving process.

Gold Mining with a good little washplant Les and I built

Gold Mining with washplant
This is a setup that Les and I put together for mining Co. Last year and it is performing very well.

Gravel pumps are a good alternative to hauling fines if………. you have a big pit to pump them into and design your mining plan around pumping, water and sand some distance away from your primary screening and recovery system. You can use sluices or centrifugal systems as well as simple jigging,  or what you design your system for.

Every property is different, mining plans change, usually on going. I have used a lot of different systems over the years and I prefer lots of sluice boxes for gold and it has been very effective.  Diamonds and Sapphires require a lot more engineering and experience . The lighter specific gravity of the two minerals will take much more tending to and a lot more parameters to deal with.
