Mar 13, 2019 (R Tuomi) - Mineralized zone has been tested by drilling for a length of 488 m. Best Zn assay was 2.4% over 2.0 feet; best Pb assay was 0.70% over 5.0 feet; best Cu assay was 0.09% over 5.0 feet; best Ag assay was 0.16 oz/ton over 5.0 feet; best Au assay was trace. Most assays were less than 1% of combined Zn, Pb and Cu (Shklanka, 1969).
Mar 13, 2019 (Therese Pettigrew) - Zinc contents of >1% Zn over 20 m were present in silicified rocks in M-12-4 (Assessment file 42C12NE2002). Sample Z06865 assayed 15049 ppm (1.5049%) Zn and 110 ppb Au over 0.3 m from DDH WR02-01, from a coarse-grained, semi-massive pyrite-pyrrhotite-sphalerite zone in a sericite-muscovite schist with quartz-eyes (Assessment file 42C12NE2006).
