Jan 17, 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 1, 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. Samples taken from outcrop stripped using a 3" pump (see Fig. 4) at showing number 2 did not yield any. The lack of abundant observed zinc mineralization in the marble should not be seen as very discouraging, as the marbles are in areas extensively covered in swamp and overburden. Also, the Cavendish marbles do appear favourable to host a polymetallic Mississippi Valley Type (MVT) deposit
