Moho Resources Ltd (ASX:MOH) has reported encouraging results for the first nine holes of the Phase 2 reverse circulation (RC) drilling program as part of its resource definition studies, to infill and extend gold mineralisation, at the East Sampson Dam (ESD) prospect.
The master composite metallurgical test work is underway with the resource model and JORC mineral resource estimate targeted in the first half of 2021.
Excellent progress
Moho Managing Director Shane Sadleir said: “Moho’s exploration team continue to make excellent progress at East Sampson Dam.
“The initial phase 2 RC drill results extend gold mineralisation down plunge at the southern end of the prospect and highlight the potential to discover additional gold mineralisation at the prospect”
Phase 2 drilling results
Phase 2 of the current resource infill drilling program finished in early January 2021 and totalled 45 holes for 3,850 metres of drilling.
The drilling highlighted a number of significant gold intersections. They included:
- SSMH0102: 2 metres at 4.48 g/t from 100 metres including 1 metre at 8.31 g/t from 100 metres;
- SSMH0103: 3 metre at 1.13 g/t from 115 metres;
- SSMH0105: 6 metres at 2.3 g/t from 105 metres including 1 metres at 3.63 g/t from 105 metres, including 1 metres at 6.80 g/t from 110 metres;
- SSMH0109: 2 metres at 2.98 g/t from 58 metres including 1 metres at 5.26 g/t from 58 metres; and
- SSMH0110: 2 metres at 2.61 g/t from 61 metres including 1 metre at 4.27 g/t from 62 metres.
Moho continues to experience long delays of up to eight weeks in receiving assay results from Perth assay laboratories.
Additional ESD RC assay results will be reported as they become available.
Geophysical logging of RC holes
Following the completion of drilling at the East Sampson Dam in January 2021, Moho contracted Wireline Services Ltd from Perth to undertake downhole logging with geophysical probes of the seven diamond holes and 10 RC holes.
The output from this work was magnetic susceptibility, density and calliper, as well as televiewer (optical and acoustic) data for each hole.
These data will be used to elucidate structural information and rock density to aid resource modelling and planning of further drill holes.
Phase 2 test work
JT Metallurgical Services of Perth have been commissioned to finalise sighter test work started in 2020 and prepare a master composite of likely mill feed from the ESD prospect and complete test work as soon as possible.
Moho has also been in discussions on parameters for phase 2 test work using diamond drill core or current high-grade RC samples.
Next steps
Going forward, the company plans to undertake the following:
- Collate Phase 2 RC drilling assay results when available along with downhole density and structural – first quarter of 2021;
- Complete metallurgical sighter test work with master composite analysis – first or second quarter 2021;
- Complete review of downhole logging and diamond drill data to define structural controls on gold mineralisation – first quarter 2021;
- Review geotechnical consultant report on ESD diamond core and site visit – first quarter 2021;
- Air core drilling of auger gold anomalies and geophysical targets north of ESD – first half of 2021; and
- Resource model and JORC resource – first half 2021.
