Dec 07, 2005 (G Seim) - Exploration diamond drilling by Falconbridge Limited in 1999 resulted in DDH G015-03 intersecting an interval of anomalous zinc and copper values within a sedimentary sequence, near the contact with a pillowed, variolitic mafic volcanic flow. A weighted average grade of 0.23% Zn, 0.04% Cu / 11.58 metres was returned from this interval. Included in this interval an assya of 0.52% Zn over 1.0 m. Descriptions in the drill log indicate that the mineralogy consists of 8-10% fracture/vein controlled pyrite; 1-2% fracture/vein controlled pyrrhotite; 0.5-1% disseminated/blebby sphalerite.
