Nov 15, 2016 (Andrew Tims) - GoldenShare 2014 identified the location of the Main Cu Showing by the position of 3 drill casings, which were the only remaining evidences for previous exploration work. The casings are oriented ENE, with a shallow dip of -30°. The geology of the area consists of basalt, generally fine grained and dark green to black. At places, the rock may be slightly to moderately amphibolitized, and more or less chloritized where the rock is more foliated. Minor rusted zones consisting of sulfides range from trace to 0.5% Po with trace Cp.

Mar 20, 2008 (Mark Puumala) - Atkinson et al. (1990) report that the Senet Main Copper showing occurs as narrow gossan-stained chert horizons hosted within biotitic, moderately-sheared mafic metavolcanic flows. The mineralized chert horizons strike 155. Atkinson et al. (1990) also observed highly-strained, drag folded and crenulated mafic metavolcanics immediately to the northwest and along strike with the showing. Foliation in the mafic metavolcanics is oriented 314/80. These rocks also host discontinuous, boudinaged quartz veins and narrow units of felsic to intermediate interflow metasediments and tuffs. Downie (1996) notes that the rocks hosting the Main Copper showing were originally mapped by Ayres (1972a) as felsic metavolcanics. However, he has re-interpreted these units as silicified mafic metavolcanics that have been intruded by fine-grained quartz diorite sills. Mineralization at the main copper showing is described by Downie (1996) as consisting of chalcopyrite and pyrrhotite with local veins of magnetite and minor grunerite. Parker (1999) suggested that this showing is of the volcanogenic massive sulphide type. Ayres (1972a) reports that the mineralized zone has been traced by diamond drilling over a strike length of 275 m, and has an approximate width of 20 m. The mineralized horizon is reported to strike between 330 and 335, and contains average copper grades ranging from 0.2 to 0.4% Cu. Significant assay values from this zone that were reported by Senet Copper included chip samples of 2.55% Cu over 5.5 m and 1.9% over 1.5 m and diamond drill intersections of 3.53% Cu over 1.8 m, 1.96% Cu across 3.6 m and 1.1% Cu over 6.4m. Ayres (1972b) also reported a gold assay of 0.2 oz/ton from a surface grab sample. 1997 diamond drilling by Wolfden Resources designed to test this showing at depth did not return any significant results (Downie 1997).
Jul 31, 2019 (Therese Pettigrew) - Samples collected during the 2014 prospecting program returned assays of up to 0.34% Cu, 0.15% Zn, 0.22 ppm Au, 10.7 ppm Ag, and 23.0 pppm As (Assessment report 20000008320). Early Precambrian metabasalts, tuff and metasediments are cut by felsic intrusives. Mineralization occurs as disseminations and stringers, and locally as massive concentrations of sulphides including pyrite, pyrrhotite, and chalcopyrite,. The main showing is on claim KRL 33410 and consists of two mineralized lenses in a weakly sheared locally silicified metabasalt. Trench samples assayed 2.55% Cu over 18 feet, and 1.90% over 5 feet with 9 feet off barren material between the two sections. On claim KRL 33407 to the south of the main showing, DDH S1, dip 30 degrees, N75E, intersected metabasalt between 158 and 170 feet, which averaged 1.85% Cu. Chalcopyrite and pyrite are also recorded in quartz porphyry between multiple auriferous quartz veins on KRL 36756 (the Springer Showing), approximately 244 m southeast of the main showing (SMDR 00508).
