In December 2024, China turned off the tap.
Without warning, Beijing imposed export controls on antimony, the metal inside every artillery shell, every set of night vision goggles, and every armor piercing round US forces fire.1
Prices rocketed past $40,000 a ton, and the Pentagon committed nearly $1 billion to rebuild stockpiles it had quietly drained for decades.2
Then came the admission no defense official wanted to make. The United States mines zero antimony at home and imports 100% of what it uses.3 More than 80% of the world’s antimony processing happens inside China.4
That is not a supply chain headache. It is a national security gap with no quick fix, and antimony is only the first of three.
Consider tungsten, the hardest metal on earth and a core component of armor piercing rounds and hypersonic missiles. It has had no US mine production since 2015, and the price ran up 557% in a single year.5
The Pentagon now faces a hard deadline to stop buying Chinese tungsten for defense work by January 1, 2027.6
And gold has pushed above $4,500 an ounce, up more than $1,100 in just twelve months.7
Three war metals. Three simultaneous supply crises. One Idaho property that holds all three.
Stibnite 2.0: One Mountain, Three Strategic Metals
The property is called Horse Heaven. It spans 14,580 acres across 729 federal mining claims in Valley County, Idaho, and Resolution Minerals Ltd. (ASX:RML) (OTCQB:RLMLF) owns 100% of it.8
What makes the address extraordinary is the neighbor. Horse Heaven sits on the eastern boundary of Perpetua Resources’ (NASDAQ:PPTA) fully permitted Stibnite Gold Project, a roughly $2.71 billion company that just secured a $2.9 billion loan from the US Export-Import Bank.9
It is the largest loan under the Make More in America initiative, awarded to build what Washington calls the country’s only identified domestic antimony reserve. The geology on both sides of that boundary is described as virtually identical: the same gold antimony system, the same district, the same range.
Now the gap. Perpetua carries a market cap near $2.71 billion. Resolution Minerals carries roughly $70 million. That is a 38 to 1 spread between two companies sitting on the same rock.
CEO Craig Lindsay does not soften the comparison. “I refer to Horse Heaven as Stibnite 2.0,” he says.10

Why All Three War Metals Are Moving at Once
Washington is already responding. The Defense Logistics Agency awarded a $245 million antimony stockpile contract to United States Antimony Corp. (NYSE:UAMY),11 and by late 2025 the Pentagon’s total critical minerals stockpiling effort had topped $1 billion.12
Tungsten tells the same story with sharper numbers. By early May 2026, APT Rotterdam prices reached roughly $3,185 per metric tonne unit, up nearly 900% over twelve months, after Beijing restricted exports to just 15 approved companies.13
BMO Capital Markets analyst George Heppel called it the tightest tungsten market in 12 years, adding, “This isn’t like lithium, where there was a huge pipeline of projects that could come online.”14
The market is on notice. The only question left is which projects can actually deliver domestic supply.

Antimony Ridge: The Mine That Armed Two World Wars
Antimony Ridge is not a hopeful prospect. It is a past-producing mine with 3,000 feet of historic open pits that supplied antimony to US troops through World War I, World War II, and the Korean War.15
The grades are the headline. Historic workings ran from 10% up to 50% antimony, among the richest ore ever recorded in North America.16
Modern rock chip sampling from the existing pits averages 40% antimony.17 The best single sample returned 49.8% antimony, 1,420 grams per tonne silver, and 3.12 grams per tonne gold, pulled straight from material sitting in the historic trenches.
Hold that against the neighbor. Perpetua’s Stibnite, the project Washington just financed, grades below 1% antimony. Antimony Ridge is more than 40 times that grade.
The metallurgy backs the rock. Test work achieved 99.5% sulphide recovery from feed grading around 10.5% antimony, and a separate process produced 99.38% antimony trioxide.18
Permitting is already moving. In April 2026 the project secured FAST-41 transparency coverage from the White House Permitting Council, locking in an agreed federal timeline with the Boise National Forest.19
Golden Gate: A Gold Discovery That Starts at Surface
On the other side of the property, Resolution drilled 14 holes at Golden Gate in 2025 and hit gold in every single one.20 That is a 100% success rate across a target three kilometers long and up to 300 meters wide.
The intercepts speak for themselves. One hole cut 253 meters at 1.50 grams per tonne gold from surface, another 197 meters at 1.26 grams per tonne, each starting at or near surface and ending in open mineralization.
Phase 2 is already turning, with up to 13,700 meters across 45 holes and two rigs running.21
The first three holes of 2026 returned strong alteration and veining 500 meters south of last year’s best hits, in ground never drilled before.22
Then there is the bonus metal. Golden Gate hosts a historic tungsten mine that once ran at 1.5% to 2% WO3, and Resolution acquired the nearby Johnson Creek mill plus roughly 2,000 tonnes of stockpiled ore.23
Early test work upgraded that material to a 52.3% WO3 concentrate, a nineteen fold jump from the starting grade.24 Gold metallurgy returned 94% to 95% recovery on oxide samples.
As tungsten prices ran up 900% in a year, that is not a small piece of optionality.
6 Reasons
This May Be the Most Mispriced Critical Minerals Story in America
1
A 38 to 1 valuation gap. Same district, same metals, same geology as a neighbor worth $2.71 billion, yet Resolution trades near $70 million.
2
Grade nobody in the district can match. Antimony Ridge averages 40% antimony versus under 1% next door, on the exact metal Washington just spent $2.9 billion to secure.
3
A gold system that starts at surface. Fourteen holes, fourteen hits, mineralization open at depth, and a maiden resource targeted for early 2027.
4
White House permitting status. FAST-41 coverage means public timelines and federal agencies held to schedule. Open ended permitting has killed more juniors than bad geology ever has.
5
A neighbor doing the heavy lifting. Perpetua is upgrading road access and building a power line through the region, infrastructure Horse Heaven shares at no cost.
6
Funded, no debt, NASDAQ close. A$28.2 million in cash, zero debt, an A$20 million placement led by Tribeca and L1 Capital, and a dual listing expected within weeks.25
The Comparison Washington Already Made
The path from a small-cap Idaho junior to a federally backed, multi-billion-dollar mine in this exact district has already been walked next door. The $2.9 billion EXIM loan is Washington’s signal that the whole district is a national security asset.
Resolution Minerals Ltd. (ASX:RML) (OTCQB:RLMLF) is the only company with a large-scale, high-grade antimony project immediately adjacent to the Stibnite district, at grades 40 times higher than what Perpetua is mining.
The People Who Have Built This Before
The most overlooked signal in a junior miner is the team. Austin Zinsser served as Senior Resource Geologist at Perpetua’s Stibnite project for 12 years, while it grew from a $50 million junior to over $2 billion, and he has consulted on Horse Heaven since 2022.
CEO Craig Lindsay has taken four companies from start-up to sale, including Otis Gold, acquired by Excellon Resources, and Magnum Uranium, acquired by Energy Fuels. Incoming director Brett Lynch built Sayona Mining, now Elevra Lithium, into a multibillion-dollar North American producer, and Dr. Adam Roper, who holds a PhD in antimony geochemistry, is building the processing flowsheet in house.
A News-Rich Stretch Is Just Beginning
Lindsay describes the months ahead as “a news-rich cycle from here through the end of the year, a lot of it from the drill bit.”
May to August 2026: Rolling gold and tungsten drill results from the 45-hole Golden Gate program, two rigs active.
Late spring 2026: NASDAQ dual listing, opening the door to US institutional capital that cannot hold a foreign-exchange position.
Q2 to Q3 2026: Antimony Ridge bulk sampling permit advancing under the FAST-41 timeline, plus tungsten stockpile sales.
Q4 2026 to Q1 2027: Maiden gold resource estimate at Golden Gate and high-grade development planning at Antimony Ridge.
The Window Is Open Now
Step back and look at the setup. China cut antimony, tungsten ran 900%, and gold cleared $4,500, while the US government wrote a $2.9 billion check to build an antimony mine in Idaho, right next door.
Resolution Minerals owns the property on the other side of that boundary, with antimony grades over 40 times Stibnite, a gold system that starts at surface, and a market cap of roughly $70 million against a neighbor worth many times that. Gaps like that do not stay open forever.
