Vancouver — Another batch of drill results from StrataGold’s (SGV-T, SAGDF-O) Tassawini project in northwestern Guyana has defined new areas of gold mineralization.
Infill and deep drilling at Tassawini West returned a 53.9-metre intercept (from 28.5 metres down-hole depth) grading 5.4 grams gold per tonne (cut grade of 3.3 grams gold) in hole SD120, including a 30-metre section of 9.1 grams gold (cut grade of 5.3 grams gold). The program shows significant gold mineralization in the bedrock below the saprolitic horizon, to depths of 180 metres.
Drilling also indicates that the recently discovered Mine Creek zone is continuous with Tassawini West, forming a larger zone of mineralization.
Additional drill results from Black Ridge and Tassawini South and East continue to return both consistent and significant gold values over good widths.
Recent preliminary metallurgical testing of samples from Black Ridge and Tassawini East and West indicate gold recoveries averaging about 95% from saprolite composites using carbon-in-leach (CIL) treatment. Transition zone composites showed gold recoveries of 73% to 91% and the fresh rock composites returned 78% to 93% gold recoveries using CIL. As expected, finer grinding delivered higher recoveries.
Gold at Tassawini occurs in a highly weathered greenstone terrane of northeasterly trending and folded metasediments, with mineralization structurally controlled and associated with a hydrothermal graphite-carbonate-pyrite-arsenopyrite-pyrrhotite assemblage and quartz veins. The saprolite is rock that has been weathered in place to an almost clay consistency, forming a horizon at Tassawini extending from surface to depths of at least 65 metres. True widths of individual zones range from 10 metres to well over 50 metres.
StrataGold posts a $115-million market capitalization given its 106 million shares outstanding and recent $1.08 trading level. The stock has a 52-week range of 53 to $1.70.
