01 / The Market

A 10× price spike, a sealed border,
and zero domestic supply.

Antimony moved from forgotten industrial metal to weaponized strategic resource in twelve months. Price up tenfold. Imports cut off. Pentagon writing nine-figure cheques to anyone who can produce it on American soil.

Export Block

China weaponized antimony exports.

August 2024 saw export controls. December 2024 tightened them, targeting the U.S. specifically. Prices ran from ~$5,000/t to ~$51,500/t.

Domestic Supply

No marketable U.S. antimony since 2015.

USGS Mineral Commodity Summary 2025 confirms it. The U.S. imports 20–25,000 t/year — most from China, before the ban.

Defense Critical

Hardens armor-piercing rounds. Powers night-vision optics.

Also flame retardants, semiconductors, and grid-scale batteries. The Pentagon describes it as "irreplaceable."

Capital Flowing

$245M DOD contract. $80M Stibnite Project grant.

Sept 2025: DOD's five-year sole-source deal with U.S. Antimony Corp. Perpetua Resources took an $80M grant. Domestic Sb is now national-security capital.

02 / The Discovery

Five tons of stibnite from one trench.

Not a cherry-picked assay. Bulk-grade material at surface — hand-shovelled in 1947, vein traced 300 ft along strike with a bulldozer in 1951–52, and untouched by modern tools ever since.

04 / The Geology

A schist-belt vein system,
structurally controlled, open at depth.

Setting
  • Bales claims sit within a schist belt along the Methow Valley structural corridor.
  • Host rock: hornblende-quartz diorite with cataclasis and recrystallization.
  • Adjacent units: andesite to the west; arkose and granite to the east; schist hosts the belt.
  • Major N–S faults bound the schist belt — primary structural controls on Sb mineralization.
  • Antimony Queen, Stibnite Prospect, and Coyote sit on the same trend to the south.
Vein geometry
  • Strike N47°E · Dip 80°SE — steep, classic high-grade orientation.
  • Mineralized zone up to 5 ft thick, bounded by shears.
  • Three components: altered wall rock + quartz + lenticular stibnite masses.
  • Massive stibnite up to 1 ft thick in places.
  • System open along strike and entirely untested at depth.
Mineralogy
  • Stibnite (Sb₂S₃) — primary high-grade Sb mineral; lenticular masses + veinlets.
  • Stibiconite — surface oxidation product; deeper system likely fresh sulphide.
  • Quartz with drusy vugs — classic hydrothermal antimony assemblage.
  • Calcite, chlorite, sericite, iron oxide — alteration envelope.
  • Trace pyrite/arsenopyrite — neighbouring properties carry 1–3 oz/t Au.
Historic workings
  • Discovery trench (1947) — ~5 tons of lump stibnite removed.
  • Bulldozer trenching exposed vein continuously for 200 ft SW of trench.
  • Additional 100 ft NE lens (4 in × 20 ft) confirmed.
  • 1951–52 production ore shipments documented.
  • 120-ft drift, stope, 110-ft adit reported (USGS MRDS).
  • All work confined to surface — zero modern drilling.

05 / The Thesis

Five reasons this asset matters now.

01

Bonanza-grade surface discovery.

10.9% Sb assay plus 5 tons of hand-removed lump stibnite. Real grade. Real material.

02

Clean ore — low-arsenic.

~0.2% As across three analyses. Smelter-friendly concentrate. Real economic edge.

03

Critical-mineral premium.

Antimony at ~$51,500/t and rising. DOD funding flowing. National priority status.

04

Untested at depth, open at strike.

300+ ft surface trace. Never drilled. Vertical and along-strike extensions all open.

05

Tier-1 U.S. jurisdiction.

Washington State. Road-accessible. BLM/USFS land. Standard permitting. Established district.
