Moho Resources Ltd (ASX:MOH) has intersected high-grade bedrock gold mineralisation within a broader zone of gold and arsenic anomalism at the Silver Swan North Project in Western Australia.
The results are from Moho’s drilling programs carried out at the Omrah and Wise Nickel prospects in late 2021 /early 2022.
A total of 14 holes were completed totalling 3,060 metres of drilling.
Broad envelope of gold mineralisation
High grade bedrock gold mineralisation was intersected in RC hole 21SSC009 close to Tyrell’s gold prospect:
- 3m (metres) @ 4.27 g/t Au (gold) from 106m including 1m @ 11.6 g/t Au from 106m
- 2m @ 0.42 g/t Au from 110m
- 2m @ 0.79 g/t Au from 113 including 1m @ 1.24 g/t Au from 113m
- Mineralisation located within broader 29m-wide anomalous envelope averaging 0.5g/t Au
RC (reverse circulation) Drillhole 21SSC009 intersected a broad envelope of gold mineralisation from 106m downhole.
The gold mineralisation is contained in a felsic volcanic unit associated with minor pyrite mineralisation and quartz veining.
Resemblance to East Sampson Dam gold deposit
Interestingly it can be noted the mineralised interval shows elevated arsenic concentrations and iron oxidation of volcanic units which bear resemblance to mineralised structures intersected at Moho’s East Sampson Dam gold deposit.
Moho managing director Shane Sadleir said: “The high-grade bedrock gold intersection within a broad zone of anomalism in 21SSC009 is very encouraging and reinforces the prospectivity of the gold trend recently identified by Aircore drilling across the Tyrells and Hodges Gold prospects.”
Diamond drilling
Only one hole was drilled for a total of 319.4 metres (484.5 metres total depth), extending from the bottom of hole 21SSC005.
This drill hole, which was designed to test the conductive EM (electromagnetic) plate at the Omrah target, intersected two conductors:
- 1st Conductor intersected at 377.2m downhole and identified to be a black shale unit associated with massive pyrrhotite mineralisation
- 2nd Conductor intersected at 480m downhole identified as large shear zone
- Hole cased for follow-up down-hole EM survey
Next steps
- Down-hole EM surveying of diamond hole and RC holes
- Geochemical review of Black Swan south and greater Silver Swan North Project
- Ground EM survey at Black Swan South
- Drilling of updated geochemical and geophysical targets
