Alto Metals Encounters More High-Grades at Vanguard

/in /by

THE DRILL SERGEANT: Alto Metals (ASX: AME) claims to have confirmed high-grade mineralisation identified by a maiden RC drilling program at the Vanguard prospect, within the company’s 100 percent-owned Sandstone gold project in Western Australia.

Alto Metals explained mineralisation confirmation came from assay results from one metre sample intervals of previously announced four metre composite sample results.

High-grade intercepts of up to 77 gram-metres were returned from oxide and fresh (primary) dolerite:

SRC013
6 metres at 5.3 grams per tonne gold from 52m, including 2m at 9.2g/t gold from 52m;

SRC014
12m at 3g/t gold from 87m and 5m at 4.8g/t gold from 103m;

SRC016
2m at 5.5g/t gold from 64m and 18m at 4.3g/t gold from 122m, including 12m at 5.6g/t gold from 126m;

SRC017
11m at 2.2g/t gold from 69m; and

SRC019
8m at 3.6g/t gold from 39m, including 2m at 7.2g/t gold from 44m and 7m at 5.9g/t gold from 52m, including 3m at 11.6g/t gold from 53m

From these results, Alto said it had become apparent the primary mineralisation at Vanguard is hosted in dolerite, which the company considers to be a favourable host rock for larger gold deposits in WA, citing examples of the Barton Dolerite at Northern Star Resources’ Jundee deposits and Gold Fields’ Argo-Junction deposits at St Ives.

“The discovery at Vanguard of open-ended high-grade mineralisation in a dolerite host rock is very encouraging as the largest gold deposit in the St Ives region (at Argo-Junction) and the multimillion ounce Jundee deposit in the Yandal Greenstone Belt are also hosted in dolerite,” Alto Metals managing director Dermot Ryan said in the company’s announcement to the Australian Securities Exchange.

Alto has reappraised the broader Sandstone Greenstone Belt, and re-prioritised its exploration strategy to focus on what it has designated as the ‘Alpha Mafic Volcanic Domain’, a zone encompassing a 20km long mafic volcanic sequence from Indomitable in the north to Maninga Marley in the south.

Alto is now designing a drilling program to extend the Vanguard mineralisation to the southwest and northeast, and to test the dolerite unit hosting Maninga Marley.

The company has lodge multiple Programs of Work with a view to the RC drilling commencing in the latter half of 2017.
