What United States Antimony's run tells us about antimony juniors

Finding a good antimony junior is harder than it sounds. Most of the names we come across have been around for years, have issued new shares many times over, or have already had their discovery moment and the price spike that went with it. So when we want a yardstick for the sector, we keep coming back to one company.

The benchmark

United States Antimony (NYSE: UAMY) describes itself as the only fully integrated antimony company outside China and Russia, and it runs the only antimony smelter in the US, in Montana. The Dallas Business Journal recently ranked it the second fastest-growing company in the Dallas-Fort Worth area, with revenue up 352% over three years. Its market value was around US$680 million at the time of writing.

A lot of that story is Washington. The company holds a sole-source Defense Logistics Agency contract worth up to US$245 million to supply the national stockpile, and it has federal support to expand its smelting capacity, according to company announcements.

Why antimony matters now

Antimony is one of those metals most people never think about. It goes into flame retardants, lead-acid batteries and military uses including ammunition. China dominates supply and has restricted exports, which is why Washington treats it as a security issue rather than just another commodity.

What we look for in the juniors

A producer like UAMY sits at one end of the curve. At the other end are newly listed explorers with a project and not much else. When we look at those, these are the questions we ask first:

• Share structure. How many shares are on issue, how many warrants are waiting to be exercised, and who holds the stock.
• Grade and history. Old production records and historical samples count as history, not a resource, until modern drilling confirms them.
• Distance to processing. An antimony deposit within trucking distance of a smelter is worth far more than one that isn't.
• Who is paying for the work. The terms of the last financing tell you a lot about how the market sees the company.
• Disclosure. Whether management tells you clearly what it owns, what it has found and what it hasn't.

None of this guarantees anything. Early-stage explorers fail far more often than they succeed, and a strong theme like antimony attracts plenty of weak companies alongside the good ones. But it is a useful filter, and it helps separate a real project from a good story.

What we're watching

The pace of UAMY's deliveries to the stockpile, antimony prices as China adjusts its export policy, and whether new US projects can be financed and permitted fast enough to matter.
