Western Mines starts 2024 Mulga Tank exploration 

Western Mines Group (ASX:WMG) remains on track to announce an initial JORC exploration target for the shallow mineralised zone within the main dunite body of the Mulga Tank Ultramafic Complex.

Exploration at itsMulga Tank Project in Western Australia has now started with programs designed to involve a combination of RC and diamond drilling.

Phasing of drilling is designed to progressively de-risk, improve confidence, and aid resource evaluation of the newly discovered nickel sulphide system.

Western Mines reports over 35 RC holes have been designed to extend and delineate a ‘significant’ mineralised zone identified in the main body of the Mulga Tank complex from initial RC results. 

An initial 17 holes are planned to be drilled during February predominantly focused on infilling the ‘higher-grade’ area. The initial RC holes will be followed by the start of a further deep diamond hole, as well as a second phase of RC drilling targeting extensions of the mineralised zone. 

The second phase of drilling aims to progressively de-risk and continue to evaluate the size of the newly discovered nickel sulphide system.   

The company notes further modelling and drill targeting work remains ongoing, with additional targets and drillholes anticipated to be announced. 

Managing Director Dr Caedmon Marriott says RC drilling is anticipated to begin in the next day or so following the clearing of drill pads and drilling the majority of the 60m pre-collars for the first RC program.  

“We’ve undertaken a lot of modelling and targeting work over the New Year period and have some exciting exploration planned at Mulga Tank for the first quarter of 2024. An initial 17 hole RC program will predominantly target infill drilling around a higher grade core in the central-eastern area of the previous RC drilling. 

This will be followed by deep diamond hole EIS3 and then further RC drilling targeting extensions of the shallow mineralisation. The phasing of the drilling should ensure steady news flow from the project over the next several months. The team has been back on site for the last 10 days. They have completed clearing the drill pads and have drilled the majority of the ~60m pre-collars for the first RC program – this RC drilling should start in the next day or so.” 

Exploration results from the company’s various drilling programs at the Mulga Tank Project over the last 12 months have demonstrated ‘significant’ nickel sulphide mineralisation and an ‘extensive’ nickel sulphide mineral system within the Mulga Tank Ultramafic Complex.

Western Mines completed a 22 hole RC drilling program in September to October 2023 designed to systematically test the lateral continuity of the shallow, uppermost zone of disseminated nickel sulphide mineralisation observed within the main body of the complex.

These holes were spaced at approximately 500m by 300m and covered a 2,500m by 1,000m area across the centre of the Complex; each hole was designed to a target depth of 300m. Results from this initial RC program have steadily been received over the past 2 months. 

Based on the results from this first RC program, implicit modelling of the RC assay results, and recent MobileMT results, the company has planned a series of drilling programs for the first quarter of 2024 involving both further RC and diamond drilling.

Western Mines Group is a mineral explorer focused on the exploration and discovery of ‘high-value’ gold and nickel sulphide deposits across a portfolio of ‘highly prospective’ projects on major mineral belts of Western Australia. 

The company’s flagship Mulga Tank project is a ‘major’ ultramafic complex found on the underexplored Minigwal Greenstone Belt. 

As of 30 September 2023, Western Mines Group had $1.872 million cash and cash equivalents at hand, according to its latest quarterly report.
