Vancouver — Gallery Resources (GYR-V) intends to commence a 3,700-metre, second-phase drill program on its Gullbridge Mine VMS property in central Newfoundland later this month.
The 30-hole program will focus on the southwest Shaft-Powderhouse zone of the past-producing Gullbridge copper mine. The first tier of 20 holes will be drilled at 50- and 100-metre centres to test for near-surface mineralization along the zone to depths of between 75 and 150 metres. A second, deeper set of 10 holes will test the downdip extension of mineralization.
A first phase of drilling on the Shaft-Powderhouse zone was completed in January. It intersected copper-cobalt-silver and gold mineralization in stringer zones and massive sulphides. A highlight of this program was a 3.2-metre interval grading 2.1% copper, including a 0.2-metre section averaging 10.2% copper, 0.09% cobalt, 42 grams silver and 0.62 gram gold.
This high-grade zone was intersected 82 metres north of the Southwest Shaft deposit and is believed to be the continuation of the Gulbridge Mine horizon, which is located 2,500 metres to the north.
As evidence to support the continuation of the horizon, Gallery cites a 2.1-metre drill intersection of chalcopyrite stringer mineralization cut by Falconbridge in 1955. The hole was drilled midway between the Southwest Shaft deposit and the main Gullbridge Mine. It stopped in mineralization and was never assayed.
Further evidence has been produced by an induced-polarization geophysical survey. It outlined a strong chargeability anomaly, which is centred over the Falconbridge hole and spans a 1.2-km section of the southwest Shaft-Powderhouse zone.
Gallery’s interpretation is also supported by data from a gravity survey performed by Rio Algom in 1991.
