Jan 18, 2017 (A Wilson) - Showings number l and 2 were discovered in the summer of 1988, while showing number 3 was found during the 1989 program. Showing number l, located 80 m southeast of post l of claim SO.2073044, consists of smithsonite coated boulders. The source of these boulders could not be traced either north or south of Salmon Lake due to extensive overburden coverage. Showing number 2 consists of smithsonite coated boulders, boulders containing bands with up to 3% sphalerite(visual observation), and outcrop containing weathered out pyrite and sphalerite grains with black hematite fracture fillings. Showing number 3 consists of smithsonite coated boulders and boulders with bands containing up to 1.% sphalerite (visual estimate). Encouraging assay values (0.97% Zn and 3.00% Zn from showing number 2 and 1.07% from showing number 3 obtained were from 2 to 3 cm wide bands containing sphalerite mineralization in marble boulders at showings number 2 and 3. These boulders appear to be local and do not appear to have been glacially transported.
