Shares of Perpetua Resources jumped 8.7% to $18.08 on November 6, extending a week-long climb that began after the company disclosed a significant new gold-antimony discovery at its Stibnite project in central Idaho. The stock had drifted near $16 for days before the November 4 drilling update landed, and the market's reaction says as much about geopolitics as geology.
A Single Drill Hole Did the Heavy Lifting. Fiddle's discovery hole, SB633, returned 109.7 meters grading 3.2 g/t gold and 1.1% antimony — grades Perpetua says are "more than double the project's life-of-mine average."
Fiddle sits roughly 750 meters south of the already-permitted Yellow Pine pit , meaning it falls outside the current mine plan. That distinction matters: the U.S. Forest Service has noted that mining in target areas not approved under the current plan requires additional environmental review and permitting. Investors are pricing in upside from mineral that may take years — and fresh permits — to reach.
The Antimony Angle Has a Ticking Clock. Perpetua holds the only identified domestic reserve of antimony , a metal used in ammunition, batteries, and semiconductors. China's U.S. export ban suspension runs only to November 27, 2026 — barely three weeks away. China published a whitelist allowing only 11 companies to export antimony globally, and the controls can be reinstated at any time. If the ban snaps back, Stibnite's strategic value ratchets higher overnight, giving the stock a built-in geopolitical catalyst.
Construction Funding Is Secured, but Production Is Still Years Out. EXIM unanimously approved a $2.9 billion loan for the project , and Perpetua's August investor presentation targets a production start in 2029.
National Bank of Canada expects shares to rise during construction, citing potential $1–$2 billion in annual earnings at full output of over 400,000 gold-equivalent ounces. But the company is still spending — its Q3 budget alone totals $177 million — without a dollar of revenue.
More Assays Are Still in the Pipeline. Clark Tunnel antimony and tungsten assays remain pending, along with results from four additional holes.
Two southern Fiddle holes also await results. Each batch could move the stock again — or disappoint. For a pre-revenue miner trading on drill results, the next few months of lab work may matter as much as the $2.9 billion check in the bank.
