06/13/2019 (T Pettigrew) - From the start of the bedrock at 17.0 m to a depth of 450.4 m, DDH RGR-17-1 intersected a package of fine-grained clastic metasediments (mainly meta-siltstone with minor meta-arenites) with intervals of various intercalated staurolite-garnet-sericite-biotite-quartz-feldspar schists and sericite dominant schists thought to be derived from felsic tuffs. The meta-siltstones vary from relatively fresh units composed largely of fine-grained biotite-quartz-feldspar through intervals with increasing amounts of garnet and staurolite into hydrothermally altered, coarse-grained schists dominated by garnet and staurolite. These schists are very similar to those encountered by drilling in the “Romios Copper-(Gold) Zone”/Lower Alteration Zone 1.5 to 3 km to the southeast. This zone is believed to continue northward and pass about 200 m east of the 2017 drill hole collar (Assessment report 20000015639).

06/13/2019 (T Pettigrew) - The mineralization encountered in this hole was primarily of two types: a massive sulphide style horizon encountered from 299.2-301.1 m and three intervals of chalcopyrite mineralized, quartz veined/flooded schists very similar to the style of mineralization in the “Romios Copper-(Gold) Zone”/Lower Alteration Zone. The best results from DDH RGR-17-1 were 2.35% Cu, 1.4 g/t Au, and 68.2 g/t Ag over 1.9 m from 299.2-301.1 m (Assessment file 20000015639).
