Locksley Resources Makes History: First American-Made Antimony Ingot in Decades
Locksley Resources (ASX: LKY) has achieved a breakthrough milestone that could reshape America’s critical minerals landscape. The company has successfully produced the first 100% American-made antimony ingot by Locksley Resources Ltd in decades, validating a complete mine-to-metal supply chain entirely independent of Chinese processing. This achievement comes from ore sourced at their Mojave Desert Antimony Mine in California and refined by Hazen Research Inc. in Colorado.
The timing couldn’t be more strategic, coinciding with Australian Prime Minister Albanese’s meetings with President Trump in Washington, highlighting Australia’s growing role in strengthening U.S. critical minerals self-sufficiency.
CEO Kerrie Matthews: “This is a defining milestone for Locksley and the United States. The successful casting of the first 100% American made antimony ingot in decades, demonstrates mine-to-metal production is not only possible but is already underway.”
Understanding Antimony: Why This Metal Matters for National Security
Antimony is a critical strategic metal essential for defence systems, semiconductors, and metal alloys. Despite the United States having no domestic antimony production currently, demand remains high due to its vital role in military applications and advanced manufacturing.
The lack of domestic production has created significant supply chain vulnerabilities for Western nations, particularly given China’s dominance in global antimony production. This strategic metal is irreplaceable in numerous applications that underpin national security and economic competitiveness.
Key Applications of Antimony:
-
- Defence and military systems components
-
- Semiconductor manufacturing processes
-
- Fire retardants and safety applications
-
- Advanced metal alloys for aerospace and automotive industries
The strategic importance of antimony stems from its unique properties that make it essential for high-performance applications. Its ability to harden other metals whilst maintaining flexibility makes it particularly valuable in defence applications.
Furthermore, antimony compounds are critical in flame-retardant materials, protecting both military and civilian infrastructure. The lack of domestic production has made antimony a critical minerals priority under multiple U.S. Presidential Executive Orders, creating substantial opportunities for companies that can establish reliable American supply chains.
Current supply chain dependencies have exposed vulnerabilities that governments and industry leaders are actively seeking to address through domestic production initiatives. In addition, the first 100% American-made antimony ingot by Locksley Resources Ltd represents a significant step toward addressing these strategic concerns.
Strategic Positioning: From Proof-of-Concept to Commercial Scale
Locksley has now validated what many thought impossible – a fully American-controlled antimony supply chain. The company is advancing through clearly defined phases that position it as a pioneer in rebuilding America’s antimony production capability.
Immediate Focus:
-
- Scale-up to U.S.-based pilot plant operations
-
- Detailed metallurgical interpretation and process optimisation
-
- Engagement with U.S. government and industrial partners
-
- Commercial pathway planning with strategic advisors
Strategic Advantages:
| Factor | Locksley’s Position |
|---|---|
| Supply Chain Control | 100% American sourcing and processing |
| Geographic Location | Mojave Project in California |
| Processing Partner | Hazen Research Inc. (established U.S. laboratory) |
| Government Alignment | Directly supports Presidential Executive Orders |

The achievement demonstrates Locksley’s commitment to delivering an antimony product sourced and refined entirely within the United States. This breakthrough directly supports U.S. government objectives to restore domestic critical mineral production, positioning the company as a key player in America’s strategic materials independence.
GreenMet CEO Drew Horn: “Locksley’s achievement is not only a technical success, but also a national milestone. The ability to produce an American sourced and American refined antimony ingot is precisely the kind of outcome that U.S. policymakers and industry leaders have been seeking.”
The company will work closely with industry partners and downstream consumers to ensure product specifications for both antimony trisulfide and antimony trioxide meet stringent U.S. defence and industrial standards. This phase will also support offtake readiness and qualification as the leading U.S. developer of domestically produced antimony metal.
However, the significance of the first 100% American-made antimony ingot by Locksley Resources Ltd extends beyond technical achievement to strategic national importance.
