Diamond Mining: Kimberlite In Venezuela

While prospecting in central Venezuela we chanced upon many artisanal miners in the bush.

You can see a family here working a shaft that was all of 50 ft straight down. Niches had been hand dug in the clay walls of the narrow shaft serving as the ladder going down. You would stretch out and basically walk straight down till you came to the adults they were working.

This I believe was one of the first photo's taken of Kimberlite found in this area in Venezuela. I was comfortable enough with going underground here, actually I could not stand it not to go check it out! They called the Kimberlite in this area Pintura. Which translates in spanish to colors. I actually held pieces with Diamonds in them.

How Diamond-Bearing Kimberlites Reach the Surface of Earth: Acidification Provides the Thrust

Diamond-bearing kimberlites are volcanic rocks that originate deep in the Earth and are erupted onto the surface. LMU researchers have now shown that other rock types incorporated into the magma as it rises through overlying formations provide the necessary buoyancy for its long ascent.

Kimberlites are magmatic rocks that form deep in Earth's interior and are brought to the surface by volcanic eruptions. On their turbulent journey upwards magmas assimilate other types of minerals, collectively referred to as xenoliths (Greek for "foreign rocks"). The xenoliths found in kimberlite include diamonds, and the vast majority of the diamonds mined in the world today is found in kimberlite ores. Exactly how kimberlites acquire the necessary buoyancy for their long ascent through Earth's crust has, however, been something of a mystery.

Our company engaged Rob Towner to do the final setup and complete the wash circuit of our pilot plant to begin a feasibility study of an ancient mining district gold concession in Mexico, in order to construct a full scale modern mining operation that will eventually run 4000-5000 tonnes per day or pay ore. Rob is without question one of the most knowledgeable, and talented miners on the planet. His experience and know-how benefited our mining team tremendously and he worked right along side our crew. His work ethics are as high as I have ever seen and he gets the job done. We were right on schedule, never missed completing the days work and finished on budget and on time. Many thanks Rob, you're our favorite Montana Mining Gringo. Best wishes from our mine to yours.

I have had Rob assist me on a number of occasions with my gold mining. When nobody else can fix it or figure it out, Rob jumps in and seems to put it all together so that what is stopped or busted starts working. I would never have got my wash plant at my mine working without his help. He knows how to keep the pay dirt being processed in the plant. I have seen him build stuff and weld stuff to get something fixed that seemed impossible but he gets 'er done just fine. Rob can read the ground like no one I have ever seen, he has thousand of ounces under his belt and my experiences with him show it. He has helped me setup my mine and plant in many different regards. I consider myself lucky I ran into Rob.
