Latest Antimony Supply News

Locksley Resources’ maiden diamond drilling at the Desert Antimony Mine reveals high-grade antimony mineralisation extending beneath historic underground workings, including a standout 33.51% Sb intercept.

Nova Minerals CEO Christopher Gerteisen highlighted progress on the Estelle Project at the Alaska Sustainable Energy Conference, emphasizing the company’s role in establishing a US domestic antimony supply chain backed by US$43.4 million in government funding.

Pantera Minerals has completed a second phase of soil and rock sampling at its Gillham Silver-Antimony Project in Arkansas, broadening key target areas and setting the stage for maiden drilling planned in mid-2026.

American Tungsten & Antimony Ltd (ASX: AT4) has raised A$10 million through a strongly supported placement and secured a 40% Utah state tax credit, underpinning its strategy to develop a domestic US supply chain for tungsten and antimony ahead of a planned Nasdaq listing.

EV Resources’ maiden drilling at Los Lirios reveals a broad, shallow antimony carbonate replacement system with promising high-grade intercepts, setting the stage for a potential bulk-tonnage open-pit development and a maiden JORC resource by Q3 2026.

Larvotto Resources has identified a significant high-grade gold-antimony-tungsten mineralised system at Curry’s Block, with diamond drilling approved to test extensions. Tungsten’s critical mineral status and record prices add strategic weight to the project’s near-mine growth potential.

Resolution Minerals has achieved 99.5% recovery of stibnite from lower grade Antimony Ridge samples, reinforcing the project's potential as a key US antimony source. Further flotation and hydrometallurgical test work is underway alongside a major drilling campaign at Golden Gate.

EV Resources has reached a critical milestone with dry commissioning of the grinding circuit at its Tecomatlán Processing Plant, setting the stage for near-term antimony production amid global supply constraints.

Larvotto Resources extends high-grade gold-antimony-tungsten mineralisation at its Metz Mining Centre, with the Midas Gully lode now stretching over 700m and open at depth, supported by new geophysical data.

Resolution Minerals has successfully produced high-grade tungsten concentrates from historical stockpiles at its Golden Gate mine, achieving a 19-fold upgrade and strong recovery rates using simple gravity separation techniques.

Locksley Resources has kicked off maiden diamond drilling at its Desert Antimony Mine and El Campo Rare Earth Element Prospect, alongside producing 99.5% purity antimony trioxide, reinforcing its push for a US domestic critical minerals supply chain.

Resolution Minerals has produced a high-purity antimony trioxide intermediate from its Antimony Ridge project using conventional pyrometallurgy, while hydrometallurgical tests progress. The project benefits from US FAST-41 permitting, aiming to establish a local processing hub for critical metals in Idaho.
