Mineralization Comments

12/18/2020 (T Pettigrew) - The J.J. Perry Extension is approximately 1 km west of the original J.J. Perry showing. Seven samples were taken for assay, all from felsic tuff/metasediments. They all returned anomalous copper values, with the highest being 1.53% Cu (sample TM-3). Sample TM-1 returned 6558 ppm Cu, 441 ppm Zn, and 0.01 oz/t Au. The nature of the mineralization here appears to be very similar to the J.J. Perry Zone (Assessment report 42L07NW0023).
