Aurizon Gold-Silver-Copper Zone

High Grade Underground Mine-Making Potential

The Aurizon Zone, located in the southeast corner of the Lac La Hache Property (yellow circle in image), is viewed by EnGold management as having the potential for high grade gold-copper-silver underground mining. EnGold has specifically targeted the Aurizon South area, which has yielded the best gold/copper/silver values within a strong structure demonstrating excellent continuity.

Drilling at Aurizon South indicates gold-copper-silver occurs within a near-vertical structure that measures at least 400m along strike (open), with true widths ranging from 2 m to more than 20 m and extending to 670 m depth with most recent drilling (open). High grades are associated with sulphide-rich (chalcopyrite, chalcocite, pyrite) hydrothermal breccia and related fractures. In fall, 2016, drilling intersected bonanza grades, exceeding 50 gpt Au and as high as 263 gpt Au, associated with quartz veins lying adjacent to the structure, featuring abundant visible gold specks and semi-massive sulphides. Quartz veins have been intersected in surface trenches, and drill holes down to more than 550 m vertical depth (open). Silicification also occurs within the main hydrothermal breccia structure, associated with improved grades (see recent assays in EnGold’s Oct. 26/16, Nov. 23/16, Dec. 21/16 and Jan 18/17 News).

Gold assays from historical and recent drilling include 10.36 grams per tonne (gpt) over 14m (downhole length), 6 gpt/8 m, 26.3 gpt/ 3 m, 6.7 gpt/6 m, 5.1 gpt/10 m, 5.7 gpt/4 m, 6.7gpt/6 m, 11.7 gpt/5 m, 10.7 gpt/2 m, 15.5 gpt/1.9 m, 15.7 gpt/1.8 m and many wider intervals of 3-4 gpt gold. Many of these intervals also carry 1-3 % copper, and 15-96 gpt silver.


Engold management’s near to medium term goal at Aurizon South is to analyze past and current drilling with a view to developing a resource estimate as soon as possible. The next phase would be to initiate a preliminary economic assessment based on the possibility of a low-footprint, underground mining operation that would ship ore directly to one of the nearby mills in the region. The goal is to develop a path to production based on low costs and reduced capital expenditures leveraging the region’s excellent infrastructure.
