Resolution Minerals (ASX: RML) continued to advance its US antimony interests and push its US-centric critical minerals strategy during the three months to end June. The company expects the mineralisation to be amenable to conventional processing methods, supporting its longer-term objective of participating in the domestic US critical minerals supply chain. Antimony Trioxide ProductionCanada’s Kingston Process Metallurgy achieved the production of an intermediate antimony trioxide product grading 99.38% purity from representative stibnite material sourced from historical workings at Antimony Ridge. Testing used conventional pyrometallurgical volatilisation techniques and demonstrated that Antimony Ridge is capable of outputting “exceptionally high purity” antimony products. “These initiatives strongly position Resolution to execute its next phase of growth as it advances the Horse Heaven project and seeks to establish itself as an emerging US critical minerals platform.”
