THE DRILL SERGEANT: Alto Metals (ASX: AME) recently drilled two 2 RC holes at the Vanguard and Tiger Moth prospects of the company’s Sandstone gold project in Western Australia.
Alto Metals reported that assay results from these holes confirmed geological models and provided samples for preliminary metallurgical testwork, which subsequently returned high recoveries and better than predicted grades.
The company said that assay results received from reconnaissance aircore drilling at Bulchina, Sandstone North and Vanguard Camp also indicates that these mineralised systems are still open, and further drilling is required.
The RC drilling confirmed robust geological models at Vanguard and Tiger Moth returning intercepts into high-grade zones including:
40 metres at 3.5 grams per tonne gold from 60m; and
SRC115 (Tiger Moth)
8m at 4.1g/t gold from 52m.
The preliminary metallurgical testwork shows recovery of +92 per cent gold from both oxide and primary gold zones.
“Alto’s recently published Mineral Resource estimate [JORC 2012] for the Indomitable and Vanguard Camps was the result of applying a systematic exploration approach,” Alto Metals managing director Dermot Ryan said in the company’s announcement to the Australian Securities Exchange.
“This process resulted in the selection and successful testing of a number of litho-structural gold targets.
“The next stage is to step-out and drill test the down dip/down plunge extensions of these newly discovered mineralised structures and convert gold mineralisation into mineral resource.”
