Excellent exploration potential for discovery of a major polymetallic, intermediate sulphidation epithermal deposit and for concealed porphyry deposits at depth.
The Buck Project deposit manifests geological and hydrothermal characteristics almost identical to major bulk-tonnage gold deposits (Blackwater-Davidson, Capoose, Newton and possibly, Snowfields and Brucejack), suggesting that good to excellent recoveries can be anticipated.
- Buck Project has large volumes of mineralization containing:
0.87 g/t gold equivalent over 88 metres
0.95 g/t gold equivalent over 91 metres
0.70 g/t gold equivalent over 266 metres
0.58 g/t gold equivalent over 229 metres
- Nearly every drill hole at Buck Project has a strongly anomalous geochemical signature, near surface and open in most directions, as indicated by:
- Drill holes 90-1, 2 and 3 to the northeast
- Drill holes BG01, 02 and 03 north
- Drill holes 89-9, 10, 11 and 12 in the southeast
- Drill hole D-6 in the west
- Drill hole 88-05 in the northwest
- Drill hole 85-39 and 40 in the southwest
Historical Drilling - Selected Drill Intersections
Exploration and discovery potential are evident (see chart below), though previous drill work has not been evenly spaced across the deposit and many large areas have not been drilled, San Marco will permit exploration drilling to focus on discovery of higher-grade mineralization in these areas.
- There is good continuity of Au-Ag grades and many drill holes end in significant Ag-Au mineralization.
- The Buck Project may have potential for overlooked brecciation that may be related to a possible diatreme (explosive breccia pipe).
- Potential presence of a concealed porphyry deposit in the vicinity of the Buck Property, based on comparisons with the Kerr, Sulphurets, Mitchell, Iron Cap and Snowfields deposits in the Iskut region of northwestern British Columbia
