Jul 15, 2014 (A Wilson) - A grab sample from a quartz vein collected by the OGS in 1972 returned an assay of 0.17 oz/t Au and 0.51 oz/t Ag. The best intersection from the diamond drilling program completed by Aurelian was 0.05 oz/t Au over 1.2 feet. Grab samples collected by Canreos Minerals Ltd. in 1984 returned a best assay of 0.20 oz/t Au and 0.58 oz/t Ag. The quartz forms a series of parallel bands up to 20 cm wide, separated by reddish sericitic bands up to 10 cm wide. Pyrite is present up to 1% in the quartz and to a lesser extent in the host rock.
