Random sampling of the latest bulk sample from the 1-metre wide Amy vein on Sur American Gold‘s (SUR-V) Comval project in the Philippines, has failed to match previously encountered bonanza grades.
Still, the latest results include assays of 144.8 grams gold and 67.4 grams gold per tonne from ongoing vein development.
Earlier this month, two bulk samples from the vein (formerly known as Tarale #7 and part of the Tarale system) averaged 656 grams per tonne. The samples, weighing 1,000 and 650 kg, were taken 1 metre apart and about 5 metres below a surface outcropping that ran 148.3 grams over 0.65 metre. The difference is considered to be a reflection of weathering.
So far, Sur has sampled 5.4 tonnes of material from the Amy vein, with the weighted average grade ringing in at 285.8 grams.
Development of the vein will resume following work to repair damage to the tunnel entrance caused by recent heavy rains.
To date, Sur American has mapped and sampled dozens of gold-bearing quartz veins at Comval. The Tarale veins themselves are part of the larger Batoto system and outcrop on the southeastern flank of the Batoto hill, across a width of 200 metres but often connected by stockworks.
Meanwhile, channel sampling on a recently discovered 65-metre-thick massive-sulphide skarn on the east side of the Agusan River on the project returned 55 metres grading 1.4 grams gold, including 15 metres of 2.6 grams gold. The skarn has been outlined over 100 metres vertically over a 500-metre strike length. The zone remains open and Sur has launched a campaign of regional and detailed mapping and sampling of numerous other skarns that occur in a 2-by-7-km belt.
