Gold mineralisation at the syenite-hosted Beattie Gold

Lithologically-controlled mineralisation is limited to the iron-carbonatised syenite. Ore consists of bulk tonnage low-grade mineralisation where gold-bearing arsenian pyrite and arsenopyrite are the dominant sulfides. Gold is invisible; it occurs as solid solution in the spongy As-rich core of pyrite.

Lincoln County Montana Gold Production

The Libby (Snowshoe) district, in southwest Lincoln County south of the town of Libby in the Libby Creek drainage basin, was the largest producer of both lode and placer gold in the county. Placer gold was discovered as early as 1867, but it was not until the early 1880's that the first mining was done, on Libby Creek (Gibson, 1948, p. 67).

Gold in Pyrite within Altai Sayan Folded Belt Gold Deposits

Abstract This article describes the result analysis of gold in pyrite for a number of some Altai Sayan folded belt gold deposits. The analyzed pyrite samples showed gold grade from 0.04 to 20.0 g/t., which proves the fact that the gold concentrations in pyrites is irregular.
