Numerous epithermal gold-silver projects are also found in the region, including Brucejack (Newcrest Mining), Ranch (Thesis Gold) and Lawyers (Benchmark Metals). 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). 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. We're very pleased with our initial work at PIL and anticipate receiving a 3-year Notice of Work later this fall, which will allow us to ramp up work to drilling in future seasons."

PIL South has an extensive copper-in-soil response that is now coupled with strong copper mineralization in outcrop samples. The Atlas target shows strong potential for high grade epithermal gold-silver mineralization. " Sampling at Spruce returned the highest copper grades ever collected on the property. " This initial program at PIL has defined a number of priority targets for follow-up work," stated ATAC's president and CEO, Graham Downs. Crews have recently completed a Phase 2 program including additional prospecting at PIL South and re-sampling of historical Atlas drill core.

Geophysical surveys identified a strong chargeability response underlying the PIL South target area within propylitically altered volcanic rocks ( Figure 5) and.

Sampling at the PIL South target returned strong mineralization in outcrop, including 3.89% copper with 173 ppm silver in a large underexplored 2.3 x 1.5 km copper-gold ± silver-lead-zinc soil anomaly ( Figure 4).

Prospecting returned high-grade samples, including 78.30 g/t gold with 2,830 g/t silver at the Atlas target ( Figure 2), and 18.40% copper with 111 g/t silver at the Spruce target ( Figure 3).
