Resource(M)

Primary:	Gold
Tertiary:	Antimony
Ore:	Gold, Orpiment, Realgar, Calcite
Gangue:	Stibnite

Production

Operation type:	Surface-Underground
Deposit type:	carbonate-hosted Au-Ag

Development status:	Producer

Geology

Host rock:	Hanson Creek Fm.
Host type:	Limestone,Siltstone
Structure:	fracture zone
Alteration processes:	Wallrock alteration of sedimentary rocks and the basalt dike was mapped in detail on three underground mine levels. Mapped alteration of sedimentary rocks included decarbonatization, dolomitization, silicification, carbon enrichment, and arsenic sulfide mineralization. Alteration of the dike progresses from deuteric to sericitic to argillic with proximity to northeast-striking faults. Silicification, also oxidation of antimony sulfides.
