San Juan, Argentina
The San Francisco de Los Andes breccia is one of the highest-grade tourmaline breccias ever discovered. Limited shallow drilling and channel sampling returned spectacular grades of 2-12 g/t gold and 0.3-3% copper over 20-40 m intervals.
The mineralogy and geological setting indicates that only the top of the breccia pipe has been exposed, with excellent potential for growth at depth and laterally. Furthermore, San Francisco de Los Andes is only one of over 60 breccia bodies mapped to date on the property.

*Intersections are not true widths and additional drilling and geological modelling of the mineralised zones in the breccia pipes is required to determine the true widths of the drill hole intersections. Intersections are selected based on a 0.5 g/t Au or 0.3% Cu cut-off grade, a minimum downhole length of 2m and a maximum waste inclusion of 2 consecutive meters. Equivalent gold (AuEq) and equivalent copper (CuEq) values are calculated assuming 100% recovery using USD$ 1770 oz Au, $23 oz Ag and $8300/t Cu (~$3.8/lb). Results from the drilling on this project can be found in Company News releases with the following dates: August 30, June 8, March 30, January 25, 2021; December 7, October 5, August 28, March 23, 2020.
