This series of posts is an attempt to use the extensive mining knowledge we have obtained through years of helping set up mining operations to help you avoid the mistakes others have made.
As an engineer for GWP, I’ve had the opportunity to work at numerous placer mining operations around the world. Some succeeded, and some failed. Some had their equipment seized by hostile government agencies. Some were unable to establish an economical supply chain due to inadequate infrastructure, Ebola, and a civil war. Meanwhile, some seemed to do everything right. However, the vast majority of failures were the result of a single issue: inadequate and inaccurate sampling.
