ASX-listed Vietnam nickel hopeful Blackstone Minerals has produced a series of encouraging results from a maiden drilling program targeting the Ban Khoa disseminated nickel sulphide prospect at its Ta Khoa project about 160 kilometres west of Hanoi in northern Vietnam. The pick of the first batch of assays from Ban Khoa was 147 metres averaging grades of 0.31 per cent nickel, 0.04 per cent copper, 0.01 per cent cobalt and 0.14 grams per tonne PGEs from 62m depth.
Despite the lowish grades, the 147m hit shows Blackstone is in a significant mineralised system that suits its bulk tonnage mining strategy.
Other notable intersections returned in the recent round of 20 diamond core holes for an aggregate drilling coverage of 4,373m included 67.7m at 0.33 per cent nickel, 0.04 per cent copper, 0.01 per cent cobalt and 0.19 g/t PGEs from 105.3m and 32.1m at 0.48 per cent nickel, 0.08 per cent copper, 0.01 per cent cobalt and 0.33 g/t PGEs from 193.1m.
Another thick zone encountered weighed in at 60.2m going 0.37 per cent nickel, 0.07 per cent copper, 0.01 per cent cobalt and 0.09 g/t PGEs from 208.6m.
According to Blackstone, Ban Khoa represents a bulk tonnage disseminated sulphide open-cut mining opportunity potentially complementing its keystone Ban Phuc open-pittable deposit about one kilometre to the south.
The Perth-company says the Ban Khoa prospect has been earmarked for inclusion in its forthcoming pre-feasibility study on the proposed development of the Ta Khoa mining,...
