Geology

Host type:Quartzite
Alteration processes:Hypogene and supergene alteration of the shear and adjacent wallrock has produced reddish hematite after pyrite, greenish scorodite after arsenopyrite, and yellow to white antimony oxides after stibnite, jamesonite and boulangerite. Sulfide and oxide alteration typically form envelopes paralleling the shear. Alteration in the footwall reaches at least 40 feet from the shear near the Vetter shaft while alteration in the hanging wall is minor. Scorodite and hematite alteration were most prevalent in the western portion of the deposit. Antimony oxide alteration becomes pervasive in the central portion where quartz-free pods of massive, striated stibnite occur (Fairbanks Exploration Inc., unpublished report, 1988).
