Redstar's Summer Exploration Program Defines Drill Targets Along 750 Meter Strike Length at the Empire Ridge Zones at the Unga Gold Project in Alaska
TheNewswire / September 22, 2016 - Redstar Gold Corp. (TSX.V: RGC, US: RGCTF, FRA: RGG) ("Redstar" or the "Company") announces results from it's summer geological mapping program at the Empire Ridge Prospect ("Empire Ridge") which is part of the Company's 100% controlled Unga Gold Project, Alaska. The Company released results from work on the Shumagin Zone on September 15, 2016 and results from the other district targets, including Orange Mountain, are expected to be released shortly.
Empire Ridge Zone Exploration Highlights:
-The exposed vein breccias at Empire Ridge are structurally, texturally and geochemically similar to breccias at Apollo and are the source of strongly anomalous gold-silver in talus and soils.
-As a result of the 2016 summer field work, an ~750m long by ~250m deep panel, occurring from the surface to above sea level, remains open to exploration for oxidized gold-silver bearing quartz-adularia +/-carbonate +/- base metal vein breccias and is a significant shallow exploration target.
-Select rock chip samples in 2014 from within the Apollo, Rising Sun and Empire Ridge areas returned high-grade gold and silver results with values up to 401 g/t Au and 266 g/t Ag.
Redstar President & CEO, Peter Ball, commented: "Detailed geological mapping during the summer at Empire Ridge has outlined the structural framework of exposures along strike of the historically-mined vein system at Apollo, where mining efforts from 1894 to 1906 produced ~500,000 tonnes at an average grade of ~10 g/t gold. The Company can now plan new diamond drill targets along the approximate 750m long by 250m deep panel along the Taurus Bench and Empire Ridge Zones that collectively, define the continuation of the Apollo vein system to the southwest of historic mine development stopes. This immediately presents a drill ready target, for a potential shallow, high-grade oxidized vein gold system."
Unga Gold Project: Apollo-Sitka Trend - Historical Overview
The Empire Ridge Prospect, located along the southeast portion of Unga Island, is part of the Apollo-Sitka trend, which is one of two, partially fault-controlled, northeast to southwest oriented semi-linear trends exhibiting near continuous hydrothermal alteration and associated gold-silver bearing vein prospects. The Apollo-Sitka trend and the parallel Shumagin trend transects the entirety of Unga Island and is over approximately 10 kilometres long (See www.redstargold.com/s/Empire_Ridge_2016 Fig. 1).
2014 exploration work performed along the Apollo-Sitka trend by Redstar and reported in a press release dated December 11th, 2014, consisted of rock chip, soil and talus sampling along a approximately 3.5km long corridor of exposed hydrothermal alteration and sheeted veins that includes the sites of historic underground mining at Sitka and Apollo (circa. 1894 to 1906) (See www.redstargold.com/s/Empire_Ridge_2016 Fig. 2). The veins are anastomosing,conjugate gold-silver bearing quartz-adularia +/-carbonate +/- base metal (Pb > Zn> Cpy ? Au + Ag)
Results from Redstar's surface work established a continuous gold and silver geochemical soil anomaly of >100ppb Au (up to 821 ppb Au) and >1.3g/t Ag (up to 21.5 g/t Ag) covering the Sitka and Apollo mine areas that extended past the limits of historic mining at the Apollo open stope by ~1.3km to the southwest through Empire Ridge to near the California Prospect (See www.redstargold.com/s/Empire_Ridge_2016 Fig. 2). Select rock chip samples of exposures of quartz-adularia carbonate veins and stockwork taken from within the Apollo, Rising Sun and Empire Ridge areas returned high-grade gold and silver results with values up to 401g/t Au and 266g/t Ag (See www.redstargold.com/s/Empire_Ridge_2016 for Table 1 for highlighted samples taken during 2014).
Summer 2016 Results: Mapping and Drill Targeting
Detailed geological mapping completed during the summer, in combination with an evaluation of historic mine maps and drill results including 2014 surface geochemical data, has outlined the structural nature of the historically-mined vein system at Apollo and has allowed the Company to properly plan drill target areas with the potential to host a southwest extension of the Apollo vein system (See www.redstargold.com/s/Empire_Ridge_2016 Fig. 2).
Volcanic units within the Apollo-Empire Ridge area consists of a northwest dipping stacked sequence dominated by feldspar ? pyroxene-phyric basalt-andesite flows and flow breccias; with lesser dacitic lithic/airfall tuffs interbedded with volcaniclastic and/or lacustrine/fluvial argillite, sandstone, conglomerate and lahars (See www.redstargold.com/s/Empire_Ridge_2016 Fig. 3). A narrow (~175 m) horizon of lithic tuffs and lacustrine sediments exposed at Empire Ridge widens to the southwest along the Apollo Trend and is exposed for ~5.0km to the southwest towards the coast at Heather (See www.redstargold.com/s/Empire_Ridge_2016 Fig. 1). This volcanic unit consists of silicic bodies, ribs and lithocaps of residual vuggy silica, haloed by patches of advanced argillic alteration identical to hypogene alteration observed at the Orange Mountain zone. The residual silica bodies and altered tuffs are "capped" by relatively unaltered competent basalt & andesite distal-to and stratigraphically above and below the more permeable altered tuff units (See www.redstargold.com/s/Empire_Ridge_2016 Fig. 3).
The continuous ~750m long gold and silver geochemical talus-soil anomaly trends to the southwest from the Apollo open stope along the north side of the Taurus bench through Empire Ridge and is correlated to subdued subcrops of stockwork veined andesite and altered lithic tuff near Taurus to exposed residual silica bodies cut by quartz-limonite breccias and quartz-adularia ? carbonate breccias along Empire Ridge (See www.redstargold.com/s/Empire_Ridge_2016 Fig. 2). The exposed vein breccias at Empire Ridge are structurally, texturally and geochemically similar to breccias at Apollo and are the source of strongly anomalous gold-silver in talus and soils. Previous dilling efforts by Alaska Apollo Mines Inc. (circa. 1983) targeted the vein system to the southwest of the Apollo open stope with 5 drill holes, 2 of which failed to reach targets due to poor drilling conditions (at Empire) and one drilled into the Apollo # 2 structure located west of the Apollo open stope. The other two drill holes intersected the Apollo vein system (one deep, one shallow) but returned poor gold-silver grades and elevated base-metal mineralization (galena-sphalerite-chalcopyrite) (See www.redstargold.com/s/Empire_Ridge_2016 Figs. 2-4).
Oxidized quartz-adularia +/- carbonate +/- base metal veins and vein breccias exposed along the ribs of the Apollo open stope and along Empire Ridge document a complex structural framework that hindered expansion of the mining efforts to the southwest. Observed structural features at Apollo include: 1) conjugate sets of vertical to moderate-southeast dipping extensional veins localized within pre-existing structures along the east side of the main stope; 2) the occurance of dilation zones and associated breccia bodies localized about vein intersection lineations that have contrasting orientations (sub-horizontal & sub-vertical); 3) high-angle, post-mineral cross faulting at the extreme southwest end of the Apollo open stope that has offset the vein system (where extensions could not be located by historic drifts and cross cuts); and 4) the overall "northwest dip" of historic mine stopes is a result of mining along multiple vein sets, juxtaposed along side one another by vertical strike-slip and northwest dipping thrust faults with minor (<10m) top-to-the-east sense of displacment, that has resulted in an apparent northwest dip of historic mine development (See www.redstargold.com/s/Empire_Ridge_2016 Figs. 2- 4).
Drilling of the vein system will require drill targets to be oriented to cross cut all vein generations and target zones of maximum dilation, centered about vein intersection lineations where gold-silver grades are likely to be enhanced (See www.redstargold.com/s/Empire_Ridge_2016 Fig. 4). A steep, northwest target will be sufficient to test the multiple vein generations southwest of Apollo and may be supplemented by scissor holes until significant intersetions are discovered. As a result of the 2016 field work, an approximate 750m long by 250m deep panel, occurring from the surface to above sea level, remains open to exploration for oxidized gold-silver bearing quartz-adularia +/-carbonate +/- base metal vein breccias and is a significant shallow exploration target.
About The Unga Gold Project
The 100% controlled Unga Gold Project covers key strategic portions of adjacent Unga and Popof Islands, approximately 900 kilometers southwest of Anchorage, Alaska.
