Infill drilling by Temex Resources (TME-V) has nearly quadrupled indicated resources in the Juby Main zone on the company’s like-named gold project, on the western extension of the Larder Lake Cadillac Fault, near Gowganda, Ont.
GeoVector Management pegs the Main zone’s higher-grade core at 8.15 million tonnes grading 1.75 grams gold per tonne, based on a cutoff grade of 1 gram gold. That’s up from the 2.2 million tonnes grading 1.8 grams gold estimated in July (T.N.M., Jul. 26-Aug. 1/04). Both estimates employ a cutoff grade of 1 gram gold per tonne.
Meanwhile, the Main zone’s upper porphyry zone, which is in the hanging wall of the higher-grade zone, amounts to 460,000 tonnes averaging 1.4 grams gold. In all, the total indicated resource weighs in at 8.6 million tonnes running 1.7 grams gold per tonne. The core resource is contained over 1 km of strike length, and to depths between 200 and 325 metres below surface. The porphyry was outlined over 325 metres of strike length to a depth of 250 metres.
An additional 3.5 million tonnes of inferred material from the core zone, gold halo and upper porphyry zones comes in at 3.5 million tonnes grading 1.65 grams gold per tonne, based on a 1 gram gold cutoff. That resource is defined over 1.2 km, and to a depth of around 300 metres, and a maximum of 500 metres in some spots.
The estimates are based on 73 drill holes (including 15 holes for more than 5,00 metres by Inmet Mining [IMN-T] in eth late 1990s) totaling 18,564 metres sunk between 2002 and late 2004. In all, the holes are spaced 15-60 metres apart, with an average spacing of 50 metres, over a strike length of 1.2 km. The figures also employ results from channel sampling on six surface trenches.
“We are encouraged by the updated resource estimate and have significantly expanded the drill indicated portion. This clearly fits our longer term corporate strategy of advancing projects within our portfolio,” said Temex CEO Brian Groves.
