Alto Metals Identifies Growth Potential at Bull Oak Mine
THE DRILL SERGEANT: Alto Metals (ASX: AME) has been carrying out a new review within the company’s 100 per cent-owned Sandstone gold project in Western Australia.
Alto Metals’ latest review is being undertaken on the historic Bull Oak gold mine and surrounding historic workings, which it says has highlighted potential for near-term resource growth.
The review has determined the style of mineralisation at the Bull Oak deposit to be multiple stacked lodes hosted within a granodiorite, similar to that observed at Lord Nelson and Lord Henry.
The intrusion has a strike length of approximately 500m and a width of up to 150m, within which gold mineralisation is not constrained.
Two deeper historic holes drilled respectively by WMC and Troy in 1985 and 2009, intersected multiple mineralised reefs with numerous instances of visible gold reported.
Alto has drilled one RC hole at Bull Oak to date to test and validate the deeper historical results and intersected multiple stacked lodes with the hole ending in mineralisation.
Alto considers the lack of recent exploration and untested mineralisation to offer an opportunity with potential to extend mineralisation below the shallow mined pit both up and down dip as well as along strike and at depth.
“Mineralisation at Bull Oak is multiple stacked lodes hosted within a granodiorite, similar to that at Lord Nelson and Lord Henry,” Alto Metals managing director Matthew Bowles said in the company’s ASX announcement.
“Most of the historic drilling at Bull Oak has been relatively shallow, however two historic holes drilled to 300 metres depth intersected multiple lodes and reported numerous instances of visible gold.
“A follow up deep hole drilled by Alto returned a wide zone 260 metres at 0.4 grams per tonne gold from 36m, including 14.1g/t gold and ended in mineralisation.
“The mineralisation is completely untested up and down dip of these intercepts, as well as at depth, and we are excited to have an RC rig arriving shortly to test these outstanding targets, that have the potential to drive near-term growth.”
