Moho dials in on possible ‘felsic porphyry intrusion’ at Crossroads

Special Report: New assays confirm there’s gold and silver mineralisation in bedrock at Moho’s (ASX:MOH) Crossroad prospect, part of the uncharted Burracoppin project.
Seven holes in Moho’s maiden shallow aircore drill program at Crossroads have hit anomalous (low grade) gold-silver mineralisation, with up to 0.61 grams per tonne (g/t) gold and 5.53g/t silver in bedrock in ‘bottom of hole’ samples.
Three holes on the broad-space traverses ended in more than 0.1g/t gold.
Significantly, the mineralisation is ‘open’ to the south, east and at depth and is located on the northern margin of a pronounced gravity low. This gravity low may represent a felsic porphyry intrusion, Moho says.
Porphyries are a real prize for juniors, responsible for ~60 per cent of the world’s copper, most of its molybdenum, and significant amounts of gold and silver.
Correlation studies by consultant geochemist Richard Carver also show that gold is associated with silver and a number of ‘pathfinder’ metals.
Moho believes that this type of mineralisation, in association with the gravity low, could indicate the presence of an intrusive-related mineralising system in the area.
Moho now plans to dial in on the source.
First, it plans to extend soil sampling in H2 2020 across paddocks to the north where crops have limited vehicular access.
The next phase of drilling south and east of past drilling — to follow up bedrock gold mineralisation — is pencilled in for the last quarter of 2020.
