Hamelin Gold Limited (ASX:HMG) has defined three new gold targets at the West Tanami Gold Project in Western Australia.
Managing Director, Peter Bewick, said processing of the recently completed airborne magnetic and radiometric survey at the West Tanami project has defined a series of new drill targets.
The survey covered the eastern third of the project area and has been merged with other available geophysical datasets to provide the first ever detailed magnetic coverage across the entire West Tanami project. The data quality is greatly improved allowing for clearer identification of potential gold mineralising structures.
“The first step in our exploration programme since the company’s Initial Public Offer and ASX listing has been immediately successful,” Mr Bewick said.
“The completion of airborne magnetic and radiometric surveys has further demonstrated the effectiveness of geophysical techniques in refining targets in the West Tanami and has completed detailed magnetics across the entire project area.
“We now look forward to the company’s first drill campaign with drill site preparation to commence in the coming weeks and diamond drilling expected to commence in March/April 2022.”
Fremlins
The Fremlins gold prospect is located 8km south of the Coyote Gold Mine that is owned by Northern Star Resources Limited and currently under care and maintenance. A series of shallow drill programs by previous explorers at Fremlins outlined gold anomalism over 6km of strike and defined two sub parallel, north south trending gold corridors with intersections including:
• 22m @ 0.6g/t Au from 45m to EOH incl. 6m@ 1.71g/t Au from 57m in FRAR011
• 30m @ 0.3g/t Au from 9m incl. 1m @ 5.72g/t Au from 12m in FRAR058
• 80m @ 0.2 g/t Au from 52m to EOH in FRRC012
Several zones of anomalous gold at Fremlins are open along strike and at depth with nine holes ending in mineralisation greater than 0.1g/t Au. Previous drilling at the prospect does not extend below 100m from surface and no drilling has been conducted at Fremlins since 2012.
The extensive near surface gold anomalism at Fremlins is similar in scale and tenor to near surface anomalies seen over several large scale (+1Moz) gold systems within the Tanami region.
The next phase of drilling at Fremlins will test for bedrock mineralisation and potential high-grade shoots within the broader areas of gold anomalism.
Schultz
The Schultz prospect is situated 16km south west of Fremlins and is defined by a discrete high amplitude magnetic anomaly coincident with a significant jog in a regional scale, Trans-Tanami orientated structure.
The magnetic anomaly has been modelled as a 400m by 300m steeply dipping pipe like feature on the margin of a large granite intrusion. The top of the magnetic anomaly is modelled to be 100m from surface.
The magnetic anomaly is untested with previous exploration activity limited to a 4m deep vacuum drilling program on an 800m by 400m grid.
Many of the gold prospects within the West Tanami project are associated with an elevated magnetic response that is interpreted to be the result of alteration associated with hydrothermal mineralising fluids. The magnetic anomaly at the Schultz prospect is more discrete and of higher amplitude than what is seen elsewhere within the project and is interpreted to be the result of more focused and intense hydrothermal fluid flow.
The focusing of gold mineralising fluids is the key element in the formation of orogenic gold deposits. Planned drilling at the Schultz prospect will target the modelled magnetic anomaly at a position approximately 200m from surface.
Ginger
The Ginger prospect is 13km west of Fremlins near the eastern boundary of the West Tanami project. Limited previous drilling at Ginger has identified gold mineralisation in quartz veins hosted in both dolerites and sediments with mineralisation open at depth. The mineralisation is within the metamorphosed and sheared margin of a granite.
Previous drill results from Ginger include;
• 12m @ 0.6g/t Au from 18m incl. 1m@ 1.9g/t Au in GRAR003 • 11m @ 0.7g/t Au from 21m incl. 1m@ 3.4g/t Au in GRAR004
• 5m @ 2.7g/t Au from 11m incl. 2m @ 6.2g/t Au in GRAR010
Drilling along the sheared granite margin at Ginger is very limited with only 160m of the margin tested by previous drilling.
Processing of the radiometric data acquired during the recent airborne survey has outlined a strongly anomalous response that correlates with the previously defined gold anomalism at Ginger and extends 2.4km to the west to the Dino prospect.
The source of the radiometric anomaly is potentially indicative of an intrusion-related gold event and the mineralisation at the Ginger and Dino prospects may extend well outside the extents of the existing drilling.
The presence of the radiometric anomaly at Ginger indicates a residual regolith profile or very shallow cover, implying the area could be amenable to surface geochemistry.
An initial field mapping and geochemical program is proposed following heritage clearance, with drilling then proposed to test at depth and along strike of the existing gold mineralisation at Ginger.
