Michael Henrichsen, CEO of Goldshore commented, “These results further validate our decision to expand the winter drill program by 5,000 meters with the objectives of deepening the Southwest conceptual open pit and to close the gap between the Southwest and Main pits.  This winter’s drill program has demonstrated the emerging nature of the Moss Gold Deposit and its growth potential.  We look forward to continued drilling to realize the full ounce potential of the deposit in the coming months.”

Technical Overview

Figure 1 shows the location of the drill holes being reported with respect to the planned winter drill program, while Figure 2 illustrates a long section through drill hole MMD-25-165 that demonstrates the potential to join the Main and Southwest Zones as a single mineralized body. Tables 1 & 2 summarize significant intercepts and drill hole locations, respectively.

Drilling has targeted the Golden Gate prospect, a critical gap in drilling data between the Main and Southwest Zones, and the surface extension of deeper modelled mineralized shear zones along the southern boundary of the Main Zone. Both areas aim to identify sufficient near surface mineralization between the conceptual Main and Southwest pits to merge the two pits together.  The shallow portion of these areas are only accessible for drilling from lake ice and can be infilled at depth from near shore drill sites.

Hole MMD-25-165 targeted a drilling data gap between the Main and Southwest zones collared into a sequence of andesitic and dacitic volcanic rocks. Swarms of weak to moderately sheared, sericite-silica-hematite altered diorite and granodiorite dykes were encountered after 200m depth becoming increasingly mineralized with depth with intercepts of 3.2m of 0.63 g/t Au from 232.1m and 12.9m of 2.64 g/t Au from 243.4 including 9.45m of 3.46 g/t Au from 9.45m (Figure 3).  Down hole orientation data does not align with either the Main or Southwest zone shears with the new mineralization likely part of a segmented lens along the Snodgrass Lake fault splay system. The hole was terminated in mineralized diorite due to depth limitations of the ice thickness.

Hole MMD-25-166 was stepped ahead by 130m of MMD-24-165 and encountered an unexpected increase in overburden thickness increasing to approximately 80m from the 38m in MMD-25-165. This resulted in an approximately 20m gap in coverage between the two holes and the erratic erosional surface beneath overburden. The hole intersected a sequence locally sericite-silica altered andesitic and dacitic volcanics rocks with frequent swarms of weakly sheared and mineralized sericite-silica-hematite altered diorite and granodiorite dykes. Where more strongly sheared, the diorite and granodiorite mineralization increased with intercepts of 2.0m of 2.81 g/t Au from 98.0m, 3.2m of 0.93 g/t Au from 117m, and 5.4m of 1.59 g/t Au from 143.6m including 0.4m of 18.2 g/t Au from 143.6m. Combined with MMD-25-165, the holes have identified a new mineralized corridor with an estimated true width of 75m between the two zones. The corridor is accessible for additional drilling from the western shore of Snodgrass Lake.

Holes MMD-25-167 and MMD-25-169 targeted the southern edge of the Main Zone aiming to extend existing shears modelled at depth to surface. Both holes collared into andesitic and dacitic volcanic rocks with frequent swarms of weakly sheared and mineralized sericite-silica-hematite altered diorite and granodiorite dykes. Both holes successfully extended existing mineralized shears towards surface at similar grades with intercepts such as 10.0m of 0.55 g/t Au from 147m including 2.0m of 1.51 g/t Au from 151m and 8.05m of 0.58 g/t Au from 185.95m in MMD-25-167 and 2m of 2.0 g/t from 61m and 27m of 0.46 g/t Au from 154m in MMD-25-169. Downhole core orientation measurements align with the expected orientation of the Main Zone shears.

Analytical and QA/QC Procedures

All samples were sent to ALS Geochemistry in Thunder Bay for preparation and analysis was performed in the ALS Vancouver analytical facility. ALS is accredited by the Standards Council of Canada (SCC) for the Accreditation of Mineral Analysis Testing Laboratories and CAN-P-4E ISO/IEC 17025. Samples were analysed for gold via fire assay with an AA finish (“Au-AA23”) and 48 pathfinder elements via ICP-MS after four-acid digestion (“ME-MS61”). Samples that assayed over 10 ppm Au were re-run via fire assay with a gravimetric finish (“Au-GRA21”).

In addition to ALS quality assurance / quality control protocols, Goldshore has implemented a quality control program for all samples collected through the drilling program.  The quality control program was designed by a qualified and independent third party, with a focus on the quality of analytical results for gold. Analytical results are received, imported to our secure on-line database and evaluated to meet our established guidelines to ensure that all sample batches pass industry best practice for analytical quality control. Certified reference materials are considered acceptable if values returned are within three standard deviations of the certified value reported by the manufacture of the material. In addition to the certified reference material, certified blank material is included in the sample stream to monitor contamination during sample preparation. Blank material results are assessed based on the returned gold result being less than ten times the quoted lower detection limit of the analytical method. The results of the on-going analytical quality control program are evaluated and reported to Goldshore by Orix Geoscience Inc.
