Updated Resource Estimate For Osiris Deposit

VANCOUVER - ATAC Resources Ltd. reported on the Mineral Resource Estimate for the Osiris Deposit, at the Rackla Gold Property, Yukon. The Resource Estimate was completed by Mine Development Associates (MDA) of Reno, Nevada, a division of RESPEC, with support from Blue Coast Research (Blue Coast) of Parksville, BC. Osiris Deposit Resource Update Highlights: Indicated Mineral Resource of 732,000 ounces gold at an average grade of 4.12 g/t (in 5.5 Mt), including pit-constrained resources of 604,000 ounces gold at 4.03 g/t (in 4.7 Mt); Inferred Mineral Resource of 1,044,000 ounces gold at an average grade of 3.47 g/t (in 9.4 Mt), including pit-constrained resources of 530,000 ounces gold at 3.07 g/t (in 5.4 Mt); Conversion of 43% of the 2018 maiden Inferred Resource (1,685,000 ounces at 4.23 g/t) to the Indicated category; All zones remain open to extension along strike and at depth; and Metallurgical testwork confirms >80% gold recoveries, and viable processing paths with flotation, pre-treatment by either pressure oxidation or roasting, and cyanide leaching.

"We are very pleased to demonstrate significant conversion of resources from the Inferred to Indicated category at Osiris," said President and CEO, Graham Downs. "This continues to demonstrate the confidence we have in this extensive, high-grade Carlin-style system that hosts some of the best gold intervals ever reported in Yukon.  Work over the past two years has focused on technical studies and modeling, leading to growth of the deposit and improved classification of part of the resources at Osiris. We have recently completed 1,500 m of drilling stepping out on open near-surface parts of the resource and look forward to releasing those results when available."
