US Department of War awards $43.4M DPA Title III funding to Alaska Range Resources for domestic antimony trisulfide production

Mechanism

Another DPA Title III micro-award in the Department of War's recurring cadence of narrowly-targeted critical-materials awards (alongside the ElementUSA gallium/scandium award, slug 2025-11-20-us-dow-elementusa-gallium-scandium-dpa-title-iii, and the REDAR/Systima SRM awards). This one funds a new domestic antimony source: Alaska Range Resources' Estelle project will extract, concentrate and refine stibnite ore into military-grade antimony trisulfide, a compound with no meaningful existing US commercial production. Antimony's criticality was sharply elevated by China's December 2024 export ban to the US (following the earlier August 2024 global licensing regime, slug 2024-08-15-china-mofcom-antimony-export-licensing) — China refines roughly 50% of global antimony supply and the ban cut off the largest prior US import source. Benchmark antimony prices have risen sharply since the ban, reflecting the shortage this award is intended to address. Severity is set at 3/5 (above the ElementUSA sibling award's 2/5): the dollar figure is comparable but antimony trisulfide is a single-point-of-failure military input (primers, case hardening) with essentially zero prior domestic refining capacity, and China's export ban makes the supply gap acute rather than precautionary.

Downstream implications

• First substantial US government capital committed to domestic

antimony trisulfide refining since China's December 2024 export ban — a direct build-a-domestic-source response on the demand side, mirroring the ElementUSA gallium/scandium pattern.

• Nova Minerals / Alaska Range Resources becomes a name to track

alongside United States Antimony Corporation (NYSE: UAMY) and Perpetua Resources as US-listed beneficiaries of antimony onshoring policy.

• Extends the steady-drip pattern of DPA Title III critical-minerals

tranches the register should expect to continue through 2026 as EO 14241 implementation continues.

Open questions

• Timeline and capacity target for the "initial phase" — no

kg/year or ton/year production figure was disclosed in the primary announcement.

• Whether follow-on Title III or Office of Strategic Capital funding

will be awarded once the initial phase reaches a scale-up decision point.

• Whether Nova Minerals secures any offtake agreements with US

defense primes tied to this award.
