Felix Gold takes Alaska antimony plan from fieldwork towards permits and refining

Treasure Creek progress meets a severe funding constraint

Felix Gold Limited (ASX:FXG) is closer to testing its Alaska antimony strategy in the field, but the September quarter also exposed the financing pressure behind it. The company completed 80 drill holes at Treasure Creek, advanced its mine permit application and converted mineralised material into cast antimony metal at pilot scale. Yet cash stood at just A$1.267 million at 30 September, after A$8.943 million of relevant quarterly outgoings.

The reported cash figure equates to 0.1 quarters of funding under the Appendix 5B calculation, which uses the quarter’s operating and exploration outflows. Felix Gold said spending should fall substantially now that field activity has wound down, with work shifting towards studies, environmental monitoring and regulatory submissions. It also said it may reduce discretionary spending and raise additional capital when required.

Mine permitting and drilling move into the next phase

At Treasure Creek, infill drilling was designed to support mine planning while step-out drilling tested extensions of the NW Array mineralisation. The first seven RC holes were reported after quarter-end, while 73 holes remained pending at the report date. The program included 45 RC holes and 35 diamond holes. The early results included the first seven step-out holes, which had previously identified a 12.19-metre gold interval grading 2.84 grams per tonne in a northern step-out hole.

Felix Gold also completed nine trenches covering 330 metres, continued extraction under its bulk-sample permit and stockpiled mineralised material. The company specifically cautioned that no grade or contained metal should be inferred from that stockpile. Environmental baseline work, civil design and mine planning were described as substantially complete, while the mine permit application is being prepared for lodgement with the State of Alaska.

Pilot plant supports the proposed US refinery

The refinery strategy produced one of the quarter’s more tangible technical milestones. A pilot plant processed Treasure Creek material through the proposed Frontier refinery flowsheet and produced cast antimony metal, with each unit operation performing as designed according to Felix Gold. The company said the route could allow direct-shipping material to avoid grinding, flotation and a concentrate stage.

That result remains demonstration-scale evidence, not commercial production. The plant operated in batch mode rather than the proposed continuous configuration; laboratory assays, recovery data, product specifications and the final refining stage were still outstanding. Frontier Antimony Refinery Corp., Felix Gold’s wholly owned US subsidiary, has also narrowed potential refinery locations and advanced preliminary engineering.

The US Department of Energy selected Frontier for negotiations covering up to US$18 million, one of nine projects in a US$162 million program. The selection is not an award: no money has been obligated, DOE approval remains required, the funded scope and amount are unsettled, and Felix Gold said the outcome is now expected later than the up-to-120-day timeframe indicated in August. The US$18 million DOE selection had earlier been described as a potential non-dilutive funding source for the proposed US antimony processing facility.

Gold provides a second exploration thread

Gold remains an additional potential development stream at Treasure Creek. Felix Gold said resource modelling for an updated NW Array estimate had commenced, while economic studies for the mine were in their final stages. Across NW Array and Grant Mine, the group reported an Inferred gold Mineral Resource of 831,000 ounces, although no antimony Mineral Resource or Ore Reserve has been declared and no feasibility, pre-feasibility or scoping study has been completed.

Regional work continued through a 675-sample soil program at Moose Creek, with results expected in the December quarter. The company’s next identifiable tests are therefore practical rather than promotional: the remaining drill assays, resource modelling, the mine permit lodgement, the economic studies and the outcome of DOE negotiations. Against those milestones sits a funding position that Felix Gold itself says may require new capital, making the terms and timing of any raise as important as the next technical result.
