Shares of Antimony Resources Corp. (CSE: ATMY) surged 10.2% to CA$0.48 on August 10, extending a rally that began after the company released high-grade drill results on August 6. The stock has now climbed roughly 20% in four trading sessions — a sharp move for a junior explorer with no revenue — as investors bet that its New Brunswick drilling campaign is building the case for a real antimony deposit in a market still reeling from Chinese export controls.
• 13% Antimony in a Single Interval Is Impressive, but the Width Is Narrow. The standout result was 13.0% antimony in hole BH-26-16 from 305.8 to 307.9 metres, with corresponding high-grade gold of 2.2 g/t over the same width.
The full mineralized zone of 3.29 metres had high-grade antimony and gold results. Headline grades matter for sentiment, but the narrow intervals — measured in fractions of a metre — mean investors should wait for the broader mineral resource calculation before sizing the prize. Management says an updated mineral model is expected in the early weeks of September.
• A September Resource Estimate Is the Next Make-or-Break Catalyst. ATMY has contracted SRK Consultants of Toronto to complete a maiden mineral resource estimate — the first-ever official calculation of how much antimony may be in the ground.
A 2025 technical report outlined a conceptual target of roughly 2.7 million tonnes grading 3–4% antimony , but that is not a formal resource. If September's estimate confirms those numbers, the stock could attract institutional interest; if it falls short, the rally could unwind fast.
• The Macro Backdrop Is Doing the Heavy Lifting. China announced antimony export restrictions in August 2024 and banned shipments to the U.S. that December, sending prices from $9.80 per pound to a peak near $27.50.
The antimony market forecast for 2026 remains structurally tight, with Chinese restrictions and defense demand arguing for prices well above pre-2024 levels. That keeps a floor under any North American antimony story, but ATMY is years from production and still exploring.
• Multiple Zones Widen the Story — and the Spending. The company has drilled over 25,000 metres across 77 holes since April 2025 , with a Q2–Q3 program targeting 13,000 metres at the Main Zone and 6,000 metres at three newly defined zones. More zones mean a potentially larger deposit, but also more capital needed for a company burning cash with zero revenue. Investors should track upcoming financing closely.
