The Mother Lode prospect was examined as a possible source of antimony in 1942 but no additional exploration was conducted due to insufficient tonnage potential (Killeen and Mertie, 1951). The prospect was idle in 1916 and was noted to be associated with a horizontal structure which may have been parallel to foliation (Brooks, 1916 B 649). 33 B 649).? the stibnite contains less that $1 per ton in gold (0.05 ounces of gold per ton) but the grade of the granite porphyry is unknown. There are also some vitreous quartz grains buried in the stibnite some of these grains showed crystal terminations (Brooks, 1916, p.
The aggregates are highly weathered, and a little pyrite occurs with the stibnite. Specimens of ore from this deposit are made up of a granular aggregate of stibnite (Brooks, 1916, p. The stibnite occurs as pods and veinlets in the schist and as a surface coating on the dike contact (Prindle, 1910). Alteration Text: Stibnite aggregates are highly oxidized and sericite alteration was observed in the granite porphyry dike.Ĭomment (Reference): Primary Reference = Brooks, 1916 (B 649)Ĭomment (Deposit): Model Name = Stibnite vein (Cox and Singer model 27d).Ĭomment (Geology): Geologic Description = The prospect consists of a sericitized granite porphyry dike which cuts a stibnite-bearing schist.
