Location: The Alice prospect is probably near the mouth of the stream that enters the east side of Nichols Bay about 1.1 miles northwest of its entrance. The coordinates are near the middle of the west boundary of section 34, T. 82 S., R. 89 E. The location is somewhat uncertain because of conflicting descriptions of the geology.
Geology: Little has been written about the Alice prospect since it was first briefly described by Chapin (1918) as chalcopyrite in irregular masses and veinlets in limestone associated with greenstone. Two shafts were filled with water in 1918. Recent mapping by Gehrels indicates that the rocks in the area are Silurian or Ordovician quartz monzonite and syenite. There is no indication of greenstone or limestone in the vicinity on his map. Gehrels names the fault that strikes through or near the likely position of this prospect as the 'Alice Claims Fault'. Maas and others (1991) collected several samples in open cuts that may be the Alice prospect. The samples consisted of silicified syenite and quartz veins with (unidentified) sulfides and contained less than 5 to 172 parts per billion gold, less than 0.1 to 8.4 parts per million (ppm) silver; 132 to 1,400 ppm copper, 5 to 9,813 ppm lead, and 28 to 3,213 ppm zinc.
Workings: Two old shafts were filled with water in 1916 (Chapin, 1918); Maas and others (1991) sampled several open cuts at or near this site.
Age: Indeterminate.
