Star Minerals Advances Tumblegum South Mining and Secures New Merredin Gold Project

Mining By Maxwell Dee 4 min read

Star Minerals has begun mining at its Tumblegum South Gold Project with high-grade gold intercepts confirmed, while also expanding its footprint by securing a large new exploration project near Merredin in Western Australia.

  • Mining commenced and mineralised material stockpiled at Tumblegum South
  • Extensional drilling returned high-grade gold intercepts up to 46.7 g/t Au
  • New 219km² Merredin Gold Project secured via low-cost tenements
  • Cash position at $2.1 million with expenditures shifting toward mine development
  • Milling agreement in place for processing ore at Catalyst Metals’ Plutonic mill

Mining Underway at Tumblegum South with High-Grade Results

Star Minerals Limited (ASX:SMS) has marked a significant milestone in its transition from explorer to gold producer, with mining operations now underway at its flagship Tumblegum South Gold Project in Western Australia. The company has completed site mobilisation, established key infrastructure, and commenced blast hole drilling. Notably, the first blast of mineralised material has been mined and stockpiled on the Run of Mine (ROM) pad, setting the stage for upcoming processing.

Extensional reverse circulation drilling conducted earlier in the year has delivered impressive results, including a standout intercept of 4 metres at 12.72 grams per tonne (g/t) gold from 46 metres depth, which includes a high-grade 1 metre section at 46.70 g/t Au. Other notable intercepts include 2 metres at 7.67 g/t Au from 105 metres, confirming the continuity of high-grade mineralisation beyond the initial pit design. These results underpin the company’s confidence in resource growth and support ongoing mine planning efforts.

Strategic Milling Partnership with Catalyst Metals

Star Minerals has secured a gold milling agreement with Catalyst Metals Limited (ASX:CYL), allowing up to 250,000 tonnes of ore from Tumblegum South to be processed at Catalyst’s Plutonic mill under commercially competitive terms. This arrangement is a crucial component of Star Minerals’ production ramp-up strategy, enabling efficient toll treatment while minimising upfront capital expenditure on processing facilities.

Expansion Through New Merredin Gold Exploration Project

In a move to broaden its asset base, Star Minerals has secured a substantial new gold exploration project near Merredin, Western Australia. The 219 square kilometre project was acquired through low-cost tenement applications, providing exposure to a large folded magnetic trend extending over 14 kilometres with multiple structural targets prospective for gold mineralisation. Located approximately 30 kilometres from the Edna May processing plant, recently acquired by Forrestania Resources (ASX:FRS), the project benefits from established regional infrastructure including road and rail networks.

Star Minerals plans to focus on securing land access and stakeholder agreements, integrating historical exploration data, and prioritising targets through geological and geophysical studies. Early-stage reconnaissance and remote sensing programs will refine areas for follow-up exploration, aiming to build a pipeline of quality assets complementary to the Tumblegum South mine development.

Financial Position and Expenditure Shift

At quarter end, Star Minerals held cash reserves of approximately AUD 2.1 million, alongside Catalyst Metals shares valued at around AUD 1.16 million. The company’s expenditure profile is evolving as Tumblegum South progresses from exploration to mine development, with $121,000 spent during the quarter on resource management and modelling activities, alongside $22,000 on exploration and evaluation. Operating cash outflows totalled $734,000 for the quarter, reflecting ongoing investment in project advancement and corporate costs.

Payments to related parties, including director fees, amounted to $55,000 during the period. The company’s capital structure remains stable with 255.98 million ordinary shares on issue.

Navigating the Transition from Explorer to Producer

Managing Director Ashley Jones highlighted the quarter as a pivotal phase for Star Minerals, emphasizing the commencement of mining under the Right to Mine Agreement with MEGA Resources and the establishment of ROM stockpiles ahead of processing at Catalyst Metals’ mill. The acquisition of the Merredin project aligns with the company’s strategy to build a diversified portfolio of quality gold assets, with further project opportunities under review.

The company’s forward-looking statements underscore inherent uncertainties, particularly around exploration success at Merredin and production ramp-up timelines at Tumblegum South. Nonetheless, the combination of high-grade drilling results, operational progress, and strategic partnerships positions Star Minerals to advance its goal of becoming a sustainable gold producer in Western Australia.

Bottom Line?

Star Minerals is actively shifting gears from exploration to production, with mining underway and new projects expanding its growth runway, though early-stage exploration and cash burn warrant close monitoring.

Questions in the middle?

  • How quickly will processing at Catalyst Metals’ Plutonic mill translate into gold production and revenue?
  • What exploration results will emerge from the newly secured Merredin project, and how might they impact Star Minerals’ resource base?
  • Will the company’s current cash reserves sustain operational and development activities through the next quarters without additional capital raising?
