Gold-rich banded iron formations – Ahead of the Herd

2019-3-1  Goldcorp’s Musselwhite mine, also in Ontario, is one of the largest gold mines in Canada with 1.85 million ounces in reserves. Goldcorp mines about 265,000 ounces a year from the banded iron formation that hosts the ore, which is composed of coarse almandine garnets in fine-grained grunerite. Richard (Rick) Mills.

Stratabound gold deposits in Archean banded iron

Stratabound mineral deposits, particularly of gold and associated sulfides, are widely distributed within beds of banded iron-formation in the Archean greenstone belts of Rhodesia. The occurrence of gold at the Vubachikwe gold mine has been studied together with samples of mineralized iron-formation from eight other deposits.

Banded Iron Formation - Mining Fundamentals

Banded Iron Formation - Mining Fundamentals. Banded iron formations (BIFs) are sedimentary rocks, characterized by the presence of alternating layers of iron-rich minerals - known as magnetite - and amorphous silica-rich rocks - known as cherts. Each layer is relatively thin with varying levels of thickness, measuring from a millimeter up to ...

Banded iron formations, pyritic black shale, and gold ...

Banded iron formations (BIF) are predominantly Precambrian sedimentary rocks composed of alternating layers of iron-rich minerals (commonly hematite and magnetite, but also siderite, chlorite, and grunerite) and silica-rich minerals (e.g., quartz or chert) in which the Fe content of the entire rock is at least 15 wt. %. Although typically thought of as strictly Fe resources, such as in the ...
