White Rock Minerals Ltds (ASX:WRM) systematic soil sampling has revealed a large system extending over 6 kilometres of strike east-west and up to 1.2 kilometres wide north-south at its Last Chance Gold Prospect in Alaska.
The strongest gold-arsenic response occurs in a central area of about 2 kilometres strike from the Sidewinder West target to the Pickle target and the company is now drilling to test high-priority targets.
Gold assay results have been received for all soil sampling undertaken at Last Chance target.
A total of 2,821 soil samples were taken with 11 samples better than 1 g/t gold, another 43 samples better than 0.4 g/t gold and a further 186 samples were better than 0.1 g/t gold.
White Rocks technical advisor Dr Quinton Hennigh said: “With all soil sample results now back, we are pleased to now readily see the full extent of the expansive mineralising system at Last Chance.
“Drilling has been steadily progressing with few delays. To date, all of our drill holes have encountered variable amounts of quartz veining and/or silica breccia, in places with appreciable arsenopyrite and pyrite."
Hennigh said: “We believe we are in the upper brittle regime of a very large orogenic and/or Intrusion Related Gold System.
“We are highly encouraged by observations to date and are eager to complete all planned holes before the end of season in mid to late September.”
Large system uncovered
Geological reconnaissance identified a series of hydrothermal silica breccia bodies and associated narrow quartz veins distributed over 6 kilometres of east-west strike.
Multiple zones of gold-arsenic-antimony anomalism are typically associated with quartz veining and hydrothermal silica breccia bodies.
Both silica breccias and quartz veining show evidence of extensive anomalous gold mineralisation with rock chip assay results typically ranging between 0.1 and 2.0 g/t gold.
