Resurrecting An Old Hard Rock Mine—Safety Is No Accident
March 2019 by Ron Kliewer
Now it was time for the nerve-wracking part of the job: actually removing anything from the hanging wall we deemed to be in need of removal because it was either loose, could be loose, looked loose, or we felt it was just downright dangerous
They tend to be big, coming in large to extremely large sizes. They can also be amazingly rich and produce huge amounts of very high-grade ore.
This stringer was where it was not supposed to be, and it contained nuggets that were not supposed to be there.
In part one of this two-part series on gold in Guyana, I describe artisanal mining efforts currently winning alluvial gold from small-scale placer operations located along the lower Puruni River and its tributaries.
I have figured out over the years that the winning combination is hard work, persistence, knowledge, and a little luck. This leads me to describe one of my best finds ever, a “honey hole” of placer gold, if you will.
Common thought is the switchback slows the velocity of the rushing water and gold drops out from the cut bank to a fill gravel bar within or below the switchback. I am not going to disregard that model; however, I hope to improve upon it.
Choosing the right method to move your ore and waste is all about making the right choices. Sometimes more than one method may be used during the life of a mine as an operation expands and grows.
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
