Hardrock Mining Accidents Claim Four Lives
September 2010 by Scott HarnHardrock mining in the US has been hit by a tragic streak of mining accidents in recent months.
There has been much said and written about nepotism, especially in government and business. There is, however, no written rule that would prevent any miner or prospector from hiring a spouse, children or other family members in the prospecting, mining or dredging business. There may even be tax advantages associated with that nepotism.
Epithermal Ore Deposits Associated With Tertiary Volcanism—And the Feasibility of Metal Detecting for Them
Epithermal ore deposits are common in regions of late volcanic activity, especially areas associated with Miocene and later Pliocene extrusive volcanics that have not been deeply eroded since the ore was deposited. Many are simple fissure veins, but stock-works and ore-pipes are also common.
A new preventative maintenance program utilizing environmentally friendly Vapor Corrosion Inhibitors (VCIs) is becoming a reality in major mining operations today.
So, how much rain does it take to cause a major movement of gravels in a stream and redistribute the gold? The technical answer is enough water to move the bed load of the river.
What I hope to do here is to give you some information that will help you, the reader, pick out locations that will be better for you to detect and give you a possibility of finding gold.
