ATAC Resources Ltd. Samples 18.40% Copper and 78.30 g/t Gold at its PIL Property, Toodoggone, British Columbia
ATAC Resources Ltd. announced results of Phase 1 surface exploration work at the PIL property, located in the heart of British Columbia's Toodoggone district. This work program included prospecting, mapping, and Induced Polarization ("IP") geophysical surveys. Phase 2 fieldwork was recently completed, including follow-up prospecting, mapping, and re-sampling of historical core, with results pending. The first phase of exploration work at PIL included prospecting, mapping, hyperspectral alteration sampling, soil sampling, and IP surveys. A total of 295 rock samples and 589 soil samples were collected and sent for assay, and 10 line-km of IP were completed at the Spruce, PIL South and Copper Ridge targets. Prospecting at the Atlas target returned an outcrop sample that graded 78.30 g/t gold with 2,830 g/t silver on the eastern extent of the zone, approximately 400 m east of a historical 2006 rock sample that returned 489.71 g/t gold with 6,514 g/t silver. Extensive surface alteration and gold-silver anomalism in soils and rocks is present across this zone, presenting a large and compelling target area for epithermal gold-silver exploration. Historical drilling at the Atlas target encountered mineralization at depth, including 3.33 g/t gold with 52 g/t silver over 10.0 m in hole A07-03, however only limited portions of these holes were assayed. As part of the Phase 2 program, crews returned to Atlas to re-log and sample un-assayed portions of the Atlas zone drill core. A total of 564 m of core was re-processed, with results pending. At the Spruce target, prospecting returned samples including 18.40% copper with 111 g/t silver from float, 3.65% copper with 56 g/t silver and 263 ppm molybdenum from outcrop, and 0.25% copper with 26 g/t silver and 10.9% lead from outcrop. The first sample represents the highest-grade copper value ever collected on the property. The nature and extent of mineralization at Spruce is not yet fully understood and follow-up work will be conducted in future seasons to characterize the target. Work at the PIL South target returned multiple samples with elevated copper and molybdenum, including 3.89% copper with 173 g/t silver and 119 ppm molybdenum from outcrop and 2.07% copper with 21 g/t silver and 96 ppm molybdenum in float. An IP line along the PIL South ridge returned strong chargeability anomalies extending to depth within propylitically altered Takla Group basalt flows. PIL South is a priority target that received additional prospecting and mapping during the Phase 2 work program, with 83 additional rock samples collected and pending assay. Sampling at the Copper Cliff target identified copper mineralization across 50 m of outcrop, with individual grab samples returning 2.23% copper, 1.81% copper, and 1.25% copper. Due to the steep terrain, much of the Copper Cliff area remains under-sampled and will see follow-up work in future seasons. Exploration at the Copper Ridge target has not yet explained the extensive copper-gold-molybdenum soil anomaly observed at surface. Prospecting in the main anomaly returned 1.56% copper from a narrow outcrop exposure in the center of the anomaly, but did not identify more extensive mineralization. An outcrop sample 1.6 km south returned 3.44% copper with 1.12 g/t gold on the periphery of the soil anomaly. Two IP lines were run across the Copper Ridge target, with one line returning anomalous chargeability at depth. The PIL Property is located in the Stikine Terrane and is juxtaposed against the Quesnel Terrane by the 1,000+ km long, deep seated, crustal scale strike-slip Teslin-Thibert fault approximately 8 km northeast of the property boundary. The Stikine and Quesnel Terranes are characterized by similar Late Triassic to Early Jurassic volcanic-plutonic arc complexes that host numerous copper-gold-molybdenum porphyry mines, deposits and prospects including Red Chris (Newcrest Mining), Galore Creek (Teck/Newmont), Kemess (Centerra Gold), and Mount Milligan (Centerra Gold). Numerous epithermal gold-silver projects are also found in the region, including Brucejack (Newcrest Mining), Ranch (Thesis Gold) and Lawyers (Benchmark Metals). The Property is in the heart of the 90 x 20 km, NW trending Toodoggone district in northern British Columbia in the eastern part of the Stikine Terrane. The district is underlain by volcanic and sedimentary rocks of the Early to Middle Jurassic Hazelton Group and coeval intrusive complex of the Early Jurassic Black Lake Plutonic Suite. There is a prominent northwest-trending regional structural fabric with the strata in the Toodoggone disrupted by several steeply dipping normal faults, strike-slip faults and thrust faults. The Toodoggone district contains several mineralization types including epithermal gold-silver, porphyry copper-gold-molybdenum and skarn.
