Prospecting for Gold in the United States

Small quantities of gold have been mined by placer methods in some New England States. Additional placer deposits may be discovered in the East, but prospecting will require substantial expenditures of time and money. The deposits probably will be low grade, difficult to recognize, and costly to explore and sample.

Nome Offshore Placer deposits (ARDF #NM253) Au

Gold occurs in offshore placer deposits off the coast of Nome, particularly from a point west of the mouth of the Nome River to near Penny River. From about 1960 to 1991, and especially from 1987 to 1990, there has been significant exploration and gold production. From mean lower low tide, the auriferous deposits extend seaward for about 2 miles.

Elemental mercury (quicksilver) was used extensively for the recovery of gold at both

Placer Gold Mining

The placer mining engineer should be experienced in panning samples found in shallow diggings or from existing pits. This will give him immediate indications of gold presence without fear of "salting" by an over-ambitious promoter of the project. The same capability of panning is important during the other sampling phases.
