[3] Mining activity enabled access to crustal carbonatite in a biotite-amphibolite and syenitized gneiss rock, located between an area of granite to the north and marble to the south.

[3] Geologists assess that the minerals found at the mine reached the current location about 1,050 or about 1,150 million years ago.

[3] Prospectors have worked the area of the mine since the late 19th-century, seeking mica, phosphate, and feldspar.

[6] Over the years, the mine has produced world class crystals of titanite, apatite, mica, and zircon.

[3] Silver Crater Mine is most noted for its unusual betafite crystals, which geologists have yet to sufficiently analyse to understand their geological origins.
