Jun 30, 2020 (Therese Pettigrew) - A stripped 50 feet square has exposed a granodiorite dike 45 feet wide with the typical albitized cross-fractures and coarse cubic pyrite. The dike strikes N 63 degrees E and dips 70 degrees S. The cross-fractures range from 1 tp 3 inches in width and are spaced from 1 to 5 feet apart. A well-mineralized sample of albitized material and quartz assayed 0.01 ounces per ton in gold. Values to 0.10 ounces per ton in gold across a width of 2.5 feet were reported to have been obtained from an x-ray diamond-drill hole on the showing (Chisholm, 1951). Samples from Tarbush’s 1984 trenching program returned up to 0.04 oz/t Au (1.27 g/t Au) (Assessment report 52F16NE8323). The Miles Showing consists of an area stripped by Tarbush Lode Mining in 1985 in which two granodiorite sills and one feldspar porphyry sill are exposed over a length of 300-600 metres. The sills are variable in width but generally less than 15 m wide. Mineralization at the Miles showing is variable along strike but seems generally to be best developed in the granodiorite bodies. The strongest mineralization consists of transverse and longitudinal vein sets containing up to 15% fine to coarse pyrite (although usually sulphide content is less than 2%). Alteration peripheral to the veins is primarily disseminated pyrite, with albite not being observed within trenching. Other sections of the sills are unaltered and mostly without veining. 29 grab samples taken by Tarbush from the stripped area in 1985 returned grades from trace to 1.37 g/t Au (Assessment report 20000008131).
