What management will cover
The webinar will focus on two complementary assets that form an integrated mine-to-refinery structure:
- Del Sol Refinery — hydrometallurgical antimony flake refinery located in Nevada, USA
- White Spar Antimony Mine — located in Arizona, USA; currently feeds the Del Sol Refinery
This vertical integration links production directly to processing capacity, creating a self-contained operational footprint. The White Spar mine serves as the primary feedstock source for the Del Sol facility, eliminating reliance on third-party supply for raw material. For investors, this structure reduces supply-chain risk and positions the combined assets as a turnkey antimony operation within the United States.
Why antimony matters to investors
Antimony is classified as a critical mineral by the US Government due to its strategic importance and supply concentration. The element is used in flame retardants, lead-acid batteries, defence applications, and emerging energy storage technologies. Western governments are actively seeking to secure domestic and allied sources of critical minerals, reducing dependence on non-allied supply chains.
A US-based, vertically integrated antimony operation aligns with this strategic priority. The Del Sol refinery and White Spar mine would provide AT4 with a processing and production footprint in a jurisdiction prioritising critical mineral development. For investors, this represents exposure to a commodity with structural supply-demand tailwinds driven by defence, energy, and industrial demand.
