Drill Hole A-19-153 targeted the upper portion of the high-grade core of the deposit in an area up-dip of hole A-17-137 which was drilled and reported in 2017, and intersected a phenomenal intercept of 57.79 metres (true width) grading 11.79% Zn+Pb and 19.1 g/t Ag; including a high-grade core interval of 22.61% Zn+Pb and 36.2 g/t Ag over 15.44 metres (true width).
All intersections are downhole; core interval measurements and true thickness are yet to be determined.
Significant intercepts included an impressive 35.5 grams-per-tonne gold in one drill core interval of 4 metres, 6.7 grams-per-tonne gold equivalent across 17.6 metres in another drill core, and 873 grams-per-tonne silver across 5.2 metres at another zone of the property.
When drilling between the property's 17 Zone and the Beaver Pond Zone, a relatively untouched area, the company turned up 5.42 grams of gold per tonne over 43 metres, with a core interval of 17.67 grams of gold per tonne over 9.50 metres.
In addition, Moomba-191 was deepened to selectively core intervals within the Roseneath-Epsilon-Murteree (REM) formations in order to further evaluate the shale gas potential of this interval in the Moomba Field area.
