ATAC Announces 1,685,000 oz Gold in its Maiden Inferred Mineral Resource Estimate for the Osiris Project, Yukon

VANCOUVER, British Columbia, June 18, 2018 /PRNewswire/ --

ATAC Resources Ltd. (TSX-V: ATC) ("ATAC") is pleased to announce a maiden Mineral Resource estimate for its Osiris Project at the Rackla Gold Property, Yukon.  The Osiris Project is 100%-owned by ATAC and is located outside of the area currently under option to Barrick Gold Corporation ("Barrick"). The resource estimate for the Osiris Project was completed by Mine Development Associates ("MDA") of Reno, Nevada.

Osiris Project Resource Highlights: 

• Inferred Mineral Resource of 1,685,000 ounces gold at an average grade of 4.23 g/t (in 12.4 Mt), including a pit-constrained Mineral Resource containing 1,055,000 ounces of gold at 4.08 g/t (in 8.0 Mt);
• Globally competitive discovery cost of CDN $32/oz of gold*; and,
• All zones outcrop at surface and remain open in multiple directions; a 10,000 metre drill program is currently underway to increase the Osiris resources.

"Defining a maiden resource with over one million pit-constrained ounces is a major development for the company and highlights the emerging high-grade open-pit potential. With only 78,614 metres used to define the resource we achieved an excellent discovery rate of over 21 ounces of gold for every metre drilled." states ATAC's President and CEO, Graham Downs. "Expansion drilling is in full-swing with two drills focused on step-out drilling at the eastern end of the Conrad Zone. A total of five drills are now operating between Barrick's Orion Project earn-in and ATAC's Osiris Project, representing our largest drill campaign since 2012."

"With the announcement of this maiden resource, it appears that the early stage Osiris Project may have the potential to follow a 'life-cycle' path similar to many of the large producing Carlin-deposit mines in Nevada. Many of these mines started life with an initial open pit followed by underground mining," states Ed Cope, ATAC's Technical Advisor. "In many cases, the initial discoveries expanded dramatically with additional exploration and were commonly followed by the discovery of more, and often larger, deposits resulting in the great mining camps of the Nevada trends. Classic examples are represented by the original Carlin mine, Goldstrike, Cortez and Getchell-Turquoise Ridge, to name a few."
