Early results from a 15-hole, 3,561-metre program of diamond drilling have extended the Main zone at
The holes tested several undrilled areas, including the eastern strike extension of the Juby Main zone (JMZ), and filled in gaps in the existing resource.
In July, Temex tabled an initial indicated resource for the Main zone’s high-grade core of 2.2 million tonnes grading 1.8 grams gold per tonne, based on a cutoff grade of 1 gram gold. That figure shrinks to 1.2 million tonnes of 2.3 grams gold when the cutoff grade is boosted to 1.5 grams gold.
The Main zone comprises a higher-grade core defined by equal amounts of feldspar and hornblende porphyry dykes and Timiskaming sediments with gold values of around 0.75 gram per tonne. The same sediments, with a lesser amount of feldspar and hornblende porphyry, host an associated lower-grade halo with grades ranging from 0.25 to 0.75 gram gold. The upper porphyry zone, which is in the hangingwall of the higher-grade zone, returned gold values of at least 0.75 gram per tonne.
In all, the three zones comprise an inferred resource totalling 8 million tonnes grading 1.7 grams gold at a cutoff grade of 1 gram gold, or 4.5 million tonnes of 2.1 grams gold at a 1.5-gram cutoff.
So far, results from five holes have been reported. Hole 73, a 100-metre stepout from the eastern margin of the known resource, cut a 4.3-metre core section (beginning at 67 metres down-hole) grading 3.5 grams gold, including 5.5 grams gold over the hole’s first metre. A hundred metres farther to the east, hole 72 returned 11.4 metres (from 101 metres) averaging 1.9 grams gold, including the first 5.4 metres of 2.9 grams gold; the hole also yielded 12.5 metres (from 140 metres) of 1.6 grams gold, including 3.9 metres (from 145.4 metres) of 3.4 grams gold. Nearby, hole 74 failed to cut any Main zone mineralization.
Meanwhile, drilling to the west was highlighted by a 65-metre section (from 202.1 metres) running 1.4 grams gold in hole 76. The hole also returned 4.8 metres of 4.9 grams gold beginning at 225 metres down-hole. Some 50 metres to the east, hole 75 surrendered several mineralized intervals, including 1.2 metres (from 220 metres) of 7.5 grams gold, and 12.9 metres (from 323.1 metres) of 2.8 grams gold.
The latest program also included 350 metres worth of trenching over a 420-metre strike length of the JMZ. Among the results from channel sampling in the trenches were 1.2 grams gold over 76 metres, including 2.5 grams over 5 metres, and 8.7 metres of 2.6 grams gold, including 5 metres of 3.4 grams.
A revised resource estimate is due early next year.
