Moho Resources Ltd (ASX:MOH) is in the process of collating phase-2 reverse circulation (RC) drill assays with downhole density and structural data at the East Sampson Gold prospect within the Silver Swan North Project in Western Australia’s Goldfields.
The company aims to complete metallurgical sighter test-work with master composite analysis during 2021, along with a review of downhole logging and diamond drill data to define structural controls on gold mineralisation.
Other key activities include reviewing the geotechnical report on ESD diamond core, undertake air core drilling on historic auger gold anomalies and define a resource model and mineral resource estimate.
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 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 several significant gold intersections.
All holes were sampled with a primary and duplicate sample collected on a 1m basis from the cone splitter and samples were analysed at Bureau Veritas Laboratories Perth by 40g fire assay and AAS finish, with certified reference material (CRM) inserted every 33 samples and duplicates assayed every 50 samples throughout the program.
Moho continues to experience long delays of up to 8 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 East Sampson Dam in January 2021, Moho contracted Wireline Services Ltd from Perth to undertake down hole logging with geophysical probes of the 7 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.
