Antimony Resources Navigates a Dual-Track Test as Drilling Delivers 26.9% Antimony and Permitting Momentum Builds

As Perpetua Resources breaks ground on US antimony project, Antimony Resources advances permitting and reports high-grade intercepts up to 26.9% antimony at Bald Hill.

The calculus for juniors in the critical minerals space is undergoing a quiet shift. While exploration hits still capture headlines, the market’s gaze is increasingly trained on the regulatory conveyor belt. For Antimony Resources, the stakes are now split evenly between the drill bit and the permit file — and both sides delivered fresh ammunition in recent weeks.

On the sector’s regulatory front, Perpetua Resources formally broke ground on June 1, 2026, at the Stibnite Gold Project in Idaho, the only known domestic antimony reserve in the United States. The start of construction followed a significant legal victory: on May 29, a US federal court in Idaho denied a preliminary injunction against the project, ruling that the plaintiffs had failed to demonstrate imminent irreparable harm. Perpetua noted the decision is not final and an appeal remains possible, but the company nevertheless began field work the next day, including infrastructure improvements on the Burntlog route, worker accommodation upgrades, power line enhancements, and both exploration and geotechnical drilling. Production is still targeted for 2029, underscoring the strategic importance of the project for US military antimony needs.

The Perpetua precedent carries implications that extend well beyond Idaho. For any North American antimony project — including Antimony Resources’ Bald Hill in New Brunswick — the ability to navigate permitting is fast becoming a valuation differentiator. That explains why Antimony Resources quietly shifted gears in April 2026, commissioning GEMTEC Consulting Engineers and Scientists to craft a formal permitting roadmap for Bald Hill. Preliminary discussions have already begun with provincial regulators in New Brunswick, the local municipal council, and the Ministry of Indigenous Affairs. The company is running two parallel tracks: one for resource growth, one for regulatory risk reduction.

On the exploration side, the news flow remains emphatic. In a May 13 announcement, Antimony Resources reported stibnite-bearing core intervals grading as high as 26.9% antimony, along with other intercepts of 6.9% antimony, within mineralized widths reaching 15 metres. The deepest intersection came in at 495 metres. Holes BH-26-08 and BH-26-10 both returned broad mineralized zones with higher-grade internal sections occurring below 350 metres. The standout was BH-26-10, which cut two extensive zones of mineralization.

These results add to an already substantial data set. Since the drilling program began in April 2025, Antimony Resources has completed 77 holes totaling more than 25,000 metres. The Main Zone itself extends over 600 metres of strike length and reaches depths of 350 metres, with average true widths of four to five metres and grades typically running between 3% and 4% antimony. The historic core data underpinning the Main Zone originates from Globex Mining, the property owner under whose option agreement Antimony Resources operates.

The next phase of drilling, which started on May 12, calls for approximately 13,000 additional metres in the Main Zone and another 6,000 metres aimed at better delineating three newly discovered mineralized zones. Three drill rigs are now active, testing both Main Zone extensions and the new targets. The objectives are clear: define the full footprint of the mineralized area and further de-risk the project. Beyond the Main Zone, first-pass exploration drilling is planned at the Marcus, BH Central, and BH South targets, alongside regional prospecting, mapping, trenching, and soil sampling at the Second Run anomalies. The land package has been expanded to 37 square kilometres.

A separate sector data point added further context. On June 1, Americas Gold and Silver released high-grade infill drill results from the Cosalá complex in Mexico — a project that includes antimony as a by-product. The 14 reported holes had been excluded from the October 2025 resource cut-off and are now being incorporated into an optimized mine plan for the second half of 2026. The update served as a reminder that antimony exposure is not exclusive to early-stage explorers; it is also embedded in the development plans of producing companies.

For Antimony Resources, the near-term catalysts are a blend of assay results, drilling continuity, and resource definition progress. But the company has been candid that the high-grade stibnite intervals reported so far remain preliminary — insufficient work has been completed to confirm a mineral resource. The ongoing drilling, assays, and permitting work will ultimately determine how the market prices this stock in the critical minerals and specialty metals segment. The Perpetua case has raised the bar: the market now expects both grades and governance. Bald Hill is being measured on both counts.
