The Guyana Highlands
October 2004 by Edgar B. Heylmun, PhDThe Guyana Highlands referred to here are a tropical upland area that extends from French Guiana on the east to Colombia on the west, with elevations reaching 9,219 feet. It occupies a vast and remote region between the Orinoco River on the north and the Amazon River on the south. There are mountains, tablelands, mesas, and swamps, largely impassable to those on foot.

Digging in the right spots will produce excellent results, like this group of nuggets taken by the author while metal detecting during the last few months. The biggest nugget is over an ounce.
Q: Years ago I had plans for building a home-built suction dredge called the Spartan dredge. I really loved that dredge. I now have a 12-year-old son who wants to start mining. We wanted to build our own at home but I’ve lost the plans.
Q: How do I improve my small-scale mining operation’s gold production?
Newmont Mining Corporation, Normandy Mining Ltd., and Franco-Nevada Mining Corporation announced a possible merger, which would create the world’s largest mining company. The boards of all three have approved the plan, but it is still subject to shareholder and regulatory approval.
