Tri Origin completes drilling on Sault area gold project

A 12-hole program of 2,408 metres has been completed at Tri Origin Exploration’s (TSE) Sault gold project.

Drilling on the property, 90 km north of Sault Ste. Marie, Ont., was followed by down-hole electromagnetic surveys.

Previous trenching and drilling defined a 4-km-long, gold-bearing alteration zone along a contact between felsic metavolcanic and clastic metasedimentary rocks. The alteration zone is coincident with induced polarization and airborne electromagnetic anomalies.

Three separate geophysical anomalies — the northeast, north-central and west — were tested with widely spaced drill holes.

Six holes were drilled on the west anomaly, which is 1.8 km long. Hole 15, near the central part of the anomaly, intersected a 24-metre-thick pyritic zone which included eight metres of massive sulphides. Anomalous gold values were detected over 19 metres, with values up to 1.94 grams per tonne. A hole drilled by Tri Origin in 1990, near Hole 15, intersected 7.2 grams over 0.7 metres.

Hole 17, about 200 metres south of Hole 15, missed the sulphide zone because of a diabase dyke. However, a strong, down-hole, geophysical conductor was detected.

Other holes drilled at the north and south limits of the west anomaly intersected no significant gold values.

Two holes in the northeast anomaly intersected graphitic conductors, with no significant mineralization.

Three holes drilled at the north anomaly intersected sulphide mineralization containing low gold values. Surface samples from this area have returned values up to 1.9 grams.

The company reports that drilling at its Lewis Pond gold and base metal deposit in New South Wales, Australia, is progressing and that results are expected shortly.
