We sent them a lot of information, including my presentation about the area and its potential. We were excited to learn a couple weeks later that the company was interested in the property.
Enrichment of Mineral Deposits by Weathering—Part I

Tracing Gold To Its Source
In this article I am going to talk about the different sources of gold and the clues a prospector can follow to find the source.
Determining The Optimal Crushing Size for Gravity Recovery
It’s not easy to figure out what is best without testing, and so a certain level of confusion has developed about how small the ore ought to be crushed.
Hard Rock Milling: A Matter of Scale
Most prospectors understand placer mining a lot better than hard rock mining and don’t realize the amount of work that goes into processing different types of hard rock ore.
Mineralization, Ground Balance and Metal Detecting
The right ground balance setting for the conditions you are working is critical. If your detector isn’t set properly, you will lose depth of detection, sometimes to an extreme degree.
