The 10-Ton Boulder: Expanding Grout Demolition
April 2021 by John Norman
Imagine you have located a source of virgin placer ore containing immense gold value. Now imagine that there is a 10-ton monolith of extremely hard gneiss in between you and payday.
With eight loads processed, a pumpkin-size rock fell into the hopper, stopping the whole operation until I could lift it out.
The popularity of the new Discovery Channel series Bering Sea Gold has peaked interest in what gold resources are offshore of Nome, Alaska. The Cape Nome mining district is world famous...
Once I have established the presence of gold in the sample, I collect five-gallon bucket quantities of the rock material for processing back at my shop.
...most prospectors don't even think about the conductivity of minerals, but there are some that do conduct electricity to a certain degree, so metal detectors will respond to them.
The small-scale miner has reasonable opportunity to exploit some of these small, rich placer gold deposits.
There were nice sections of vein material at the end of several drifts, like they just stopped work one day and walked away.
