My good friend Col. Shali

Going through my photo's  I found a picture of Col. Shali and myself talking about some procedures on our dredging  project some years back in India.

The good Col. was a very respected former Indian army Colonel.

We developed a strong friendship working together and we always seemed to be on the crazy edge!

How we pulled off some of our projects was amazing.

I loved working with him and miss him a bunch.

This property was mined in 1899 and still is producing economic placer gold!

producing economic placer gold!
You can see that we do not have much overburden.
If you look closely  from the roots on up…. the ground has been previously worked by a small bucket line dredge.

The dredge was very small and could not dig very deep or even get through the veneer of basketball sized rocks. On the surface, the property looked totally worked out.

When we tested this, I could not believe that they would leave these kind of values so near to the surface.

They did leave a few islands of unworked ground but not much and it gave me insight to how and why they mined this alluvial flood plane.

The surrounding geology has not changed much in 5,000 years and the wind and the arid climate no doubt reconcentrated  much of the near surface low grade alluvial fan to an enriched surface deposit that fit the economic requirements of one of the first bucket line dredges in the world.

 In 1899 this was cutting edge technology and no doubt this was a success to the group that put this dredge on this little valley deposit.

We came along 110 years later and what they considered low-grade, now meets our economic requirements for the present day mining plan that we have put together.

Panning for grade control

Panning for grade control
Pretty good cleanup on our project.  We have been on a 68 day run and its been very consistent.

 Keeping rock in the box is what will make your operation a success.

We have a panning program that insures we have a good grade control.

Our property is a fine gold deposit and this is a pan from the pay streak.

When you can keep your grade at the stockpile with these good pans, your success is very probable.

Dredging for diamonds


Dredging for diamonds Just coming up from another long dive suction dredging for Diamonds. The hard work of wrestling around a 10" suction hose gets you in amazing shape very quickly. I love diving and the challenges it brings to keep the production coming.

Read this post about ancient diamond mining tools in India.

Gold in our sluice box riffles at the end of the day

Gold in our sluicebox riffles at the end of the day
You are a happy alluvial engineer when you see the results like this at the end of a good shift.

That is the way it needs to look - gold in the riffles at the end of the day. I use expanded metal riffles on most of my plants with good results. There are many more styles and I will get to that another day.

Miners moss is the very best and there is no substitute that works as well as this material for underneath the riffles.

Mining Techniques: my first stripping job

Mining Techniques
This was my first D-8 dozer I had and was stripping my first big pit. This was way back in 1985. We had a lot of overburden but it payed off pretty good even though the price of gold was very low.

You can see how extensive the workings were in the left of the photo. The pay streak was very wide as evident of the shafts all showing the direction of the pay streak.

Towards the back of the cut we were as deep as 90 ft. We had three dozers and it was expensive but at the end of the day we had recovered 1,700 ounces of refined gold. Today that would have been a pile of bucks that's for sure. A lot of the old workings were still accessible and we roamed around the underground workings a lot. The history and how hard the old-timers worked was unbelievable.

Placer mining is an American lifestyle that represents Freedom

Placer mining
Placer mining is a lifestyle that you really have to love. To keep rock in the box, the weather does not matter and you can't get tired you gotta Go Go Go! You have to be thinking way ahead of the game, be prepared for breakdowns, pay streak anomalies  and have the proper trained help.

Going home a 5 o'clock is not happening on our jobs, there just doesn't seem to be enough time in a day. If you have any hiccups  the lights are on, to make your quota of gravel that has to be run through your wash plant to meet your budget requirements.

Placer mining is a lifestyle.

On our particular job the grade is quite low but with overburden almost nonexistent it fits our company just right. We operate with just three men and most of the time it is balanced good.
