Alto Metals Limited (ASX: AME) has intersected visible gold in drilling at the Vanguard Camp, as part of the company’s maiden diamond drilling programme at the 100% owned Sandstone Gold Project in Western Australia.
The total programme comprised 17 holes for 3,425m completed at Lord Henry, Lord Nelson, Indomitable and Vanguard deposits.
Hole SDD015 was drilled to a depth of 162.3m and is one of four diamond holes completed at Vanguard with the objective of evaluating the nature of the gold mineralisation and orientation of the mineralised structures.
A quartz-rich laminated shear vein was intersected from 107.3m to 109.2m associated with silica-sericite-pyrite alteration and one notable occurrence of visible gold at 107.4m. The structure is oriented E to ESE and dips steeply north.
The laminated vein is enveloped by a broad zone of thin (<5cm) extensional quartz veins with distinct haloes of coarse-grained pyrite best developed in an interval from 88.5m to 116.5m. The veining is hosted within a dark, fine-grained differentiated granophyric dolerite unit.
The orientation of the newly recognised laminated shear vein structure intersected in SDD015, will greatly assist in interpreting the existing mineralisation at Vanguard and help to target extensions of this growing gold mineralised system. The presence of laminated shear veins at Vanguard is encouraging, as they are known to host high-grade gold mineralisation.
Managing Director, Matthew Bowles, said this is the first diamond drilling programme ever undertaken at Vanguard, with SDD015 designed to test the grade, geology and structural orientation of mineralisation adjacent to RC drill holes SRC075, SRC114 and SRC032; which returned significant intervals of 25m @ 3.8 g/t gold from 85m (SRC075), 40m @ 3.6 g/t gold from 61m (SRC114) and 22m @ 3.3 g/t gold from 103m (SRC032).
“The visible gold intersected at Vanguard confirms the potential of the trend to host high-grade gold mineralisation,” Mr Bowles said.
“The presence and orientation of this newly recognised laminated shear vein structure intersected in SDD015 at Vanguard, will greatly assist in interpreting the existing mineralisation and help to target extensions of this growing gold mineralised system.
“To date, drilling has defined mineralisation over a two kilometre north-west, south-east trend, that remains open.
“We are looking forward to updating shareholders in the coming weeks on assays from a total of 16 diamond holes and over 120 RC holes that are currently pending from Vanguard, Lord Nelson, Lord Henry and Indomitable.”
