Vancouver — Partners Cangold (CLD-V) and Rimfire Minerals (RFM-V) have outlined a 100-by-300-metre gold-in-soil geochemical anomaly on the Thorn silver-gold-copper project, southeast of Atlin, B.C.
The target is centred on the Oban breccia, which returned up to 6,148 grams silver, 3.5 grams gold per tonne, and 43% lead in boulder grab samples. The north-trending anomaly is defined by values greater than 345 parts per billion gold, 22 parts per million silver, 1,655 ppm arsenic, 1,635 ppm lead, 177 ppm antimony and 488 ppm zinc.
“Field work on the Oban Breccia zone has defined a strong northerly trend to the controlling structure, which provides confidence in defining the drill targets,” says Cangold President Robert Archer.
A helicopter-portable backhoe exposed sericite-altered breccia peripheral to the soil anomaly but was unable to expose bedrock in the heart of the target, owing to overburden. Some 8 metres of bedrock were exposed at the outer edge of the soil anomaly, with trench results yielding up to 182 grams silver and 966 ppb gold.
“We have yet to sample bedrock from the core of the anomaly, where we are seeing extremely high metal values in soils and evidence of deep oxidation,” says Archer.
At the F zone, prospecting has identified three vein structures. The faults range from 3 to 10 metres in width and can be traced for 500 metres along strike.
Some 300 metres to the west, grab samples yielded 1,255 grams silver, 2.9 grams gold, 1.1% copper, 2.3% lead and 5.1% zinc at the M zone.
The partners aim to drill-test the Oban soil anomaly in early September.
Cangold is earning a 51% stake in the property by spending $1.2 million, issuing 250,000 shares, and paying $190,000 in staged payments over three years.
