Small Mining Operations
Gold in Guyana—Part I: Porknocking on the Puruni River Road
July 2012 by Carl Brink
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.
Lode or Placer: What Difference Does It Make?
This explains the large difference in particle sizes between placers and hydrothermal lode deposits, but also means that while the mining may be similar in some cases, the sampling and recovery techniques are usually quite different.
Selenium, Mercury and Suction Dredging—Studies Contradict CA State Water Resources Board
Federal and state regulatory agencies often cite mercury and methyl mercury in our waterways as a major factor for further restrictions on placer mining, and on suction gold dredge mining, in particular. However, these regulatory agencies are minimizing selenium and its neutralizing effects.
Placer Channel Sampling
Sampling gold placers can be rewarding, but remember to treat the samples so you are not high grading or low grading your results. Learn the rules and apply them so your samples are accurate.
Ganes Creek After The Flood
Doug told me that there had been a 100-year flood that took place in October of 2013 and it washed out part of the mile-long landing strip. It also washed a large, wide gully down below and above the camp.
Putting Together A Small Free Gold Mill—Part II
There are many smaller old hard rock mines out there—more than you might think. There are some small hard rock properties that are even open to be claimed if one does the right amount of research to find them.
Long-Term Camping Plan at Fortymile Proposed by BLM
A draft environmental assessment of a proposal to allow long-term camping by gold miners along 21 miles of the North Fork of the Fortymile Wild and Scenic River is available from the Bureau of Land Management.
Comments on Gold Rush and Bering Sea Gold Series
The 316 Mining Company has not been all that successful, but does not ever seem to learn from their past mistakes.
