The Alaska vein has been traced for approximately 1.2km along strike and varies from about 0.5 to 2 metres in width, with a strike from N10E to N10W, and dips to the east at 45° to 75°. At and near the surface, and in the upper 50 metres of historical mine workings, it consists of variable mixtures of quartz, limonite, hematite, magnetite, pyrite, chrysacolla, malachite and azurite. Below about a depth of 50 to 60 metres, the Alaska vein is reported to contain chalcocite, chalcopyrite, bornite and native copper.
Summary of 2018 Alaska Vein Drill Program
In 2018, Ridgestone completed a 12-hole, 1,430-metre diamond drill program targeting shallow depths along about 500 metres of the Alaska vein. The program was successful in confirming the presence of high-grade gold and copper mineralization. Highlights from drilling included 1.53 metres grading 36.10 g/t gold plus 1.22% copper in hole 18REB10, 3.25 metres grading 8.31 g/t gold plus 2.41% copper in hole 18REB06, and 2.0 metres grading 8.69 g/t gold plus 2.78% copper in hole 18REB02. A summary of the 2018 drill-hole assay results is presented in Table 1.
