Underground Geologic Mapping
February 2000 by Dwight Juras, PhDMapping geology underground is not difficult if one knows the procedures. This article presents the procedures that will allow any miner to produce a geologic map of their workings.
Excerpts from CMJ, our original title, published 50 years ago this month.
Tiffany & Co. plans to open its first diamond cutting and sorting plant early this year in conjunction with its investment in a diamond mine in Canada’s Northwest Territories.
This mine was a real wonder of engineering, and the water supply and drifts had to be carefully managed to keep it in operation. In fact, it didn’t close due to lack of gold, but instead closed with the fall of the Roman Empire.
Our world of precious metals showed several conflicting trends. Gold fell sharply from last month’s highs to the area between 265 and 270 and then stabilized in that area.
I started with, "Hey, Rusty, tell me about the time..." and that was all it took.
Q: What does MDB&M stand for?
I believe this is a powder-keg waiting to explode down the road—with potentially devastating effects on society—but positive implications for gold and silver.
