Redstar Gold Corp. announced that structural mapping of the Shumagin and Apollo Sitka Trends has been completed. The Study's purpose is to better understand the setting and controls of the SH-1 Zone (formerly "The Shumagin Zone") and of the gold-bearing systems on Unga Island as a whole. The study was completed by Craig Pearman BSc (Geo), formerly the Chief Geologist for Kinross in West Africa. The mapping program was focused on five of 40 distinct high prospectivity areas within the Unga Project outlined by previous drilling and surface sampling of mineralized outcrop. These targets include: the extension of the SH-1 Zone, Bloomer Ridge and Aquila on the Shumagin Trend; and brownfields targets at the Apollo and Sitka historic mine sites, as well as at Empire Ridge and Rising Sun prospects which lie along strike on the Apollo-Sitka Trend. The key findings of this work are as follows: a) The SH-1 Zone (formerly the Shumagin Zone): An interpretation of surface linear features shows that high grade gold bearing structures on the Shumagin Trend are located tangentially to dacitic intrusives. This is analogous to some gold deposits in the Refugio mining district in Chile. One of these linears indicates that the western extension of the SH-1 Zone is a southwest striking splay that extends toward Pray's Vein. Surface samples taken by Redstar at Pray's Vein have returned up to 11.8g/t Au, and a historic drill hole by Battle Mountain Gold in the late 1980s returned an assay of 2.4m grading 0.18g/t Au + 6.9g/t Ag when the hole was abandoned at -45m down-hole. In the diagram (Fig 1), pink polygons are high prospectivity drill targets and irregular circulars are suspected dacite intrusives. This interpretation suggests that the mapped structure between the SH-1 Zone and Pray's Vein may be the western extension of the SH-1 Zone and is a high priority drill target. b) Apollo-Sitka Trend: The mapping shows that historic mining at Apollo-Sitka was focused on dilational structures resulting from rotation of the strike direction within a shear duplex. This exercise revealed a new dilational structure in the immediate area of the historic Apollo mine. Furthermore, surface sampling returned assays including 104g/t Au located immediately above previously mapped mine workings where significant amounts of sulfide-hosted gold and base metal mineralization was abandoned at the turn of the 19th century as untreatable in the original stamp-mills. The underground workings, mapped and sampled by Alaska Apollo Mining in the 1990s, followed a vein for 500m of strike and returned underground assays up to 6m grading 8g/t Au with Ag+Pb+Zn credits (Fig 2). The presence of a near mine, untested dilational structure as well as high grade samples at surface with historically recorded mineralization underneath has yielded two high probability drill targets. c) Bloomer Ridge: Bloomer Ridge is located 800m south of, parallel to and 200m topographically higher than the high-grade SH-1 Zone. Ubiquitous millimetric scale, iron oxide bearing, quartz-carbonate veining has been mapped which contains up to 4.7g/t Au from surface sampling (Redstar 2019) along 1.4km of strike. The close proximity to and similarity in style of mineralization to that of the SH-1 Zone indicates the Bloomer Ridge gold may be from the same source. Further, as the Ridge is higher than the SH-1 Zone, the underlying mineralization may be better preserved than that of the SH-1 zone which means that Bloomer Ridge is a high priority target for further mapping and eventual drilling. d) Aquila: Sampling and drilling by Battle Mountain in the 1980s returned assays up to 30g/t Au at surface and assays from drill results that included 0.46m grading 103g/t Au in DDH AQAME02 which was abandoned at-48m down-hole. 2019 mapping shows two zones within a shear duplex occurring tangentially to and within 400m of a centrally located dacitic intrusive. The dilational nature of the structures at Aquila supported by high grade assays from previous drilling means that the Aquila Zone is a high probability target for further drilling.
