Rockland Resources (CSE:RKL) has reported a new gold vein discovery at its Cole Gold Mines project in Ontario’s Red Lake district.
Hole RR-26-02 from the recently completed winter program returned 16.89 grams per tonne gold over 4m at the 100%-owned property. The intercept included higher-grade zones of 10.90g/t over 1.00m and 28.40g/t over 2m.
Drilling at the historic Cole Mineshaft confirmed the gold-bearing quartz vein system explored from 1933 to 1937 and defined new veins below the deepest underground level at the 530-foot level.
Hole RR-26-03 returned 113.00g/t gold over 0.50m at 236.50m depth, approximately 53m vertically below the deepest historic workings.
RR-26-02 also returned five results exceeding 8g/t, including 28.30g/t over 0.8m, 13.20g/t over 0.7m, 11.40g/t over 1.8m, 32.60g/t over 0.5m and 28.40g/t over 2.00m.
A deep intercept from 184.55m to 185.05m with significant visible gold initially assayed 1.68g/t by standard fire assay but returned 279g/t on a gravimetric-finish reassay of the quarter-core split.
Mineralisation occurs as stacked quartz veins hosted at rheological boundaries between felsic, mafic and ultramafic rocks. Coarse visible gold was observed in multiple locations in drill core.
“The first three holes drilled proximal to the Cole Mineshaft underground workings are showing high-grade stacked vein sets,” CEO Mike England says.
“We expect assays to continue streaming in now from the 300-plus remaining samples.”
The company combined a standard fire assay with a metallic screen analysis to address the coarse-gold effect. Metallic screen results for six samples from this set of holes remain pending.
