Resolution Minerals Ltd (ASX:RML, OTC:RLMLF) earlier this week outlined progress at its Horse Heaven project in Idaho, following the announcement of its partnership with Kingston Process Metallurgy to advance metallurgical testing on high-grade antimony samples.
The company said the Canadian-based laboratory would test and process the samples to produce antimony trisulfide, with the goal of developing a process flow sheet to determine the most effective method of processing antimony from Horse Heaven.
US Chief Executive Officer Craig Lindsay told Proactive that the initiative was designed to confirm the project’s capacity to generate a marketable end product. He said the step would show investors that the company is “serious about playing a very material role in the critical metals supply chain in the United States.”
The development coincides with growing focus on US-Australia cooperation on critical minerals. Lindsay, currently in Washington, attended a luncheon hosted by Australian Ambassador Kevin Rudd marking Prime Minister Anthony Albanese’s visit and the signing of an USD 8.50 billion critical minerals framework between the two nations.
He said the event underscored the strength of the relationship between Australia and the US, with both governments expressing intent to support critical metals projects financially in both countries. Lindsay added that US Secretary of the Interior Doug Burgum spoke about the importance of innovation in resource development, commenting that “when it comes to critical metals and rare earths — mine, baby, mine.”
The company highlighted that the Horse Heaven project holds several advantages, including its historical production, strong grades, and location in Idaho. It said the project could play an early role in the rollout of domestic critical metals supply in the United States.
Resolution Minerals continues to advance work programs aimed at positioning Horse Heaven as a potential contributor to the growing US critical minerals industry.
Proactive: Resolution Minerals is partnering up with a third party to test high-grade antimony samples from its Horse Heaven project in Idaho. Joining me to give us the full rundown is Resolution’s US CEO Craig Lindsay. Craig, it’s great to have you on board with me at this very late hour — I know you’re in Washington.
Craig Lindsay: Really happy to be here. Thank you for thinking of me, I appreciate it.
Proactive: Craig, there’s so much to cover today. You’re in Washington for a very big reason — the talk of the town, of course, being the US and Australia deal for critical minerals and rare earths. But first, tell us about the third-party company you’ve partnered with. Recent sampling from historical trenches returned exceptional grades at Horse Heaven — up to 49.8% antimony and 3.12 grams per tonne of gold. What are you hoping for this time around with this partnership?
Craig Lindsay: We’ve partnered with a company called Kingston Process Metallurgy, based in Kingston, Ontario, Canada — a very well-regarded laboratory globally. The idea is to take our high-grade antimony and conduct metallurgical testing that will result in the production of antimony trisulfide.
They will develop a process flow sheet to determine the most effective way to process antimony from the Horse Heaven project. The goal is to demonstrate to the market that we have ore at Horse Heaven that can be turned into a marketable end product.
It’s a big step forward. Some people might say we’re putting the cart before the horse, but we believe taking steps like this shows the market we’re serious about playing a material role in the critical metals supply chain in the United States.
Proactive: It’s quite a step forward, and it comes amid the USD 8.50 billion deal between the US and Australia signed this week — a hot international topic. How is Horse Heaven set to benefit from this deal?
Craig Lindsay: I’ve been in Washington talking to people in the US government and the Idaho delegation about what we’re doing. I was fortunate to be invited to a luncheon hosted by the Honourable Kevin Rudd, the Australian Ambassador to the US, in honour of Prime Minister Albanese’s official visit and the announcement of this critical minerals framework between Australia and the United States.
Both governments are talking about financially supporting critical metals projects in Australia and the US. There’s a lot of excitement about it. I hadn’t realized how deep the friendship is between the two countries. Kevin Rudd received high marks for his role in negotiating this agreement, and the Prime Minister delivered strong remarks about the history and importance of the relationship.
One of the guests, US Secretary of the Interior Doug Burgum, spoke passionately about innovation over regulation in natural resource development. He said, “When it comes to critical metals and rare earths — mine, baby, mine.”
It was a great event held at the Australian Embassy, which did a fantastic job representing Australia. They were also celebrating 140 years of BHP. There was strong attendance from both governments and the mining industry.
Ideally, Resolution would like to play an active role in supporting the rollout of critical metals in the US. We think Horse Heaven has unique attributes — its grade, size potential, past production, and location in Idaho. We really think it could help get the ball rolling with the production of critical metals in the US.
Proactive: It sounds like you’ve had a very productive trip to Washington. Horse Heaven will no doubt be a key focal point for investors as the USD 8.50 billion deal begins to roll out. Craig Lindsay, US CEO of Resolution Minerals, thank you so much.
Craig Lindsay: Appreciate it. Great to see you.
