Big Hits: Lac Gold, American Tungsten & Antimony and Breakthrough

Why It Matters

These high‑grade intercepts de‑risk exploration, expand resource footprints and position the companies to meet growing demand for gold, antimony and copper, all strategic commodities in the clean‑energy and defense economies.

Key Takeaways

• Lac Gold's Astoria drill hit 1,580 g/t gold at 150 m depth
• American Tungsten & Antimony hit 10.37 m at 3.98% antimony, 0.30 m at 42.1%
• Breakthrough Minerals' Barbara hole returned 35 m at 1.34% copper, 11 m at 3.02%
• All three projects show open‑pit potential and resource expansion
• Antimony and copper are critical for clean‑energy and defense supply chains

Pulse Analysis

The Abitibi Greenstone Belt remains a world‑class gold province, and Lac Gold’s latest Astoria intercept underscores the value of structural targeting. A 1,580 g/t gold assay, just 25 m below historic underground workings, validates the company’s model that brittle zones act as fluid conduits for high‑grade mineralisation. With a 15,800‑metre drill programme underway, Lac is poised to convert these shoots into measurable resource additions, bolstering its position alongside giants like LaRonde‑Bousquet.

In the United States, antimony is climbing the list of critical minerals due to its role in flame retardants, alloys and emerging battery technologies. American Tungsten & Antimony’s 10.37‑metre, 3.98% antimony intercept – highlighted by a 0.30‑metre, 42.1% stibnite zone – signals a sizable, stratabound system that diverges from the narrow‑vein archetype typical of the region. The shallow depth and pod‑like high‑grade pockets suggest further upside as drilling expands beyond the 1% footprint currently sampled, offering a domestic supply source that could reduce reliance on Asian producers.

Copper demand is being driven by electrification, renewable‑energy infrastructure and electric‑vehicle production, making Breakthrough Minerals’ Barbara results especially timely. The maiden 35‑metre, 1.34% copper interval, with an 11‑metre, 3.02% copper core, confirms a robust, open‑pit‑compatible system that extends beyond the existing resource envelope. With a 6.5‑Mt, 0.9% copper resource already in place, the company’s ongoing 10,000‑metre campaign could unlock additional tonnage at depth and along strike, positioning Barbara as a potential contributor to the global copper supply chain.
