CMC Metals Ltd. Announces Advance Field Crews Mobilized to Silver-Polymetallic Silver Hart Property in Yukon, Canada
CMC Metals Ltd. announced that advance field crews have been mobilized to silver-polymetallic Silver Hart Property in Yukon, Canada. Crews have been working for the past two weeks managing challenging conditions associated with a record snowfall in Yukon this past winter. The advance crew is now reopening camp facilities and making other preparations for the upcoming drill program and other exploration activities that will begin mid-June. 2021 Diamond Drilling Program: The 2021 drilling program will seek to expand and better define additional high-grade silver and polymetallic (zinc, lead, copper and gold) resources at the Silver Hart Project (including both the Silver Hart and Blue Heaven claims). Drill targets will include step-outs and deeper drilling efforts to grow the known resources and infill areas where current drill spacing is insufficient to support a resource within the Main Zone, and testing of identified targets within the KW and South Zones with the goal to increase resources. Main Zone: The Main Zone consists of a large zone of high-grade silver-polymetallic veins and skarn alteration that occur within granodiorite and granites of the Cassiar Batholith and then continue to intrude stratigraphically upwards into metasediments including carbonates that have the potential to host carbonate-replacement style deposits. Currently several mineralized areas including TM, S, M and KL areas have been partially explored, resulting in an inferred resource of 7,501,300 silver equivalent ounces at a grade of 584 g/t. Throughout this zone, high grade mineralization starts at surface and has shown the potential to be suitable for open pit mining. Further drilling is designed to identify the full extent of the surface resources that may be open-pittable and to also explore the full extent of the mineralized areas within this zone at depth that could potentially be mined using underground methods. Highlights from the 2019 and 2020 exploration efforts in the Main Zone include: S Mineralized area: drill intersection comprising of 5.5 meters grading 1,139 g/t silver, 11.38% lead and 8.61% zinc; TM Mineralized area: surface trench comprising of 10.5 meters grading 898.4 g/t silver, 0.97% lead and 0.29% zinc including 5.0 meters grading 1,140 g/t silver, 0.84% lead and 0.32% zinc; TM Mineralized area: drill intersection comprising of 11.7 meters grading 993.7 g/t silver, 4% lead and 9.6% zinc; and, Significant soil anomalies including from 308 samples, 70 which were anomalous in silver with 7 samples in excess of 3,000 ppb ranging up to 16,724 ppb, 30 in excess of 1,000 to 2,999 ppb ranging from 1,045 to 2,474 ppb, and 33 samples in excess of 500 to 999 ppb. In most instances the anomalous silver samples were also coincident with zinc and lead anomalies. Phase 1 of the 2021 program will explore some of the mineralized areas at depth, explore anomalous areas between the mineralized areas that are yet to be drill tested, and possible extensions of the zone to the northeast. Drill hole data included within the 3-D leapfrog model, ground geophysical data, and the new data from the airborne geophysical data are being used to identify the new drill targets within the Main Zone. The KW zone was initially identified late in the 2019 exploration program and detailed follow-up in this zone comprised of geochemical, geological and geophysical investigations was conducted in 2020. The possible lateral and strike extent of this zone is yet to be determined. Positive geochemical surveys were completed in 2019 and 2020 that from 197 samples, produced 39 samples anomalous in silver with 3 samples in excess of 3,000 ppb ranging up to 5,960 ppb, 16 in excess of 1,000 to 2,999 ppb ranging from 1,196 to 2,051 ppb, and 20 samples in excess of 500 to 942 ppb. The South zone was initially identified early in the 2020 exploration program and detailed follow-up in this zone comprised of geochemical, geological and geophysical investigations. The possible lateral and strike extent of mineralized areas within this zone are yet to be determined. Historical and recent trenching of the area identified high grade silver-polymetallic vein mineralization, skarn alteration, and altered carbonate sequences. CMC optioned these claims in 2020 from Strategic Metals Ltd. and is yet to conduct detailed exploration of the 13 mineralized areas and 36 showings within the 1,975 hectare property. Historical exploration efforts by previous operators on the Blue Heaven claims served to identify exploration results including: Blue Zone: 1,888g/t silver over 1.48 meters over a strike length in excess of 70 meters on the B3 vein and 1,519.7 g/t silver over 1.4 meters in the B2 vein; H Zone: 2,969 g/t silver over 1.3 meters and a chip sample on a massive sphalerite-galena lens averaging 6,264.3 g/t silver, 44.5% lead and 17.6% zinc over 0.6 meters; Don Zone: 778 g/t silver and 076% lead over 3.7 meters exposed in a trench; Desire Zone: Chip samples over 35.8 meters averaging 65.5 g/t silver, 5% lead and 3.6% zinc and in another trench 115.6 g/t silver, 4.2% lead and 3.4% zinc over 24.1 meters; Orly South Zone: 1,675 g/t silver, 15% lead and 3.97% zinc over 0.15 meters and a separate grab sample grading 5,063 g/t silver and 59.7% lead; and, Orly North Zone: grab sample grading 3,748.3 g/t silver, 8.87% lead and 5.9% zinc.
