Pivotal Metals Limited reported impressive drilling results at its Horden Lake copper-nickel project. Shallow step-out drilling extended the high-grade mineralized zone by 500m, with strong EM survey support, underscoring further resource potential and reinforcing the company’s growth strategy in critical metal mining.
Pivotal Metals Limited has reported promising results from its 2025 step‐out drill program at the Horden Lake project in Quebec. The drilling has extended the deposit’s shallow mineralization 500 metres southwest, establishing a clearly defined mineralized contact zone that now spans an impressive 2,600 metres along a NE trending gabbro–sediment interface. Notable high‐grade intersections include 4.3% copper equivalent (CuEq) over 0.5 metres, 2.3% CuEq over 2.6 metres, and 3.8% CuEq over 0.9 metres—the best grades coming from the deepest holes, hinting at potential improvement with depth.
The campaign, comprising 11 diamond drill holes totaling approximately 1,556 metres, has successfully validated the company’s use of electromagnetic (EM) surveys as a robust targeting tool. The FLTEM and downhole EM techniques not only highlighted multiple large conductive anomalies along the 3,200-metre contact zone but have also identified several additional undrilled targets. These geophysical insights underpin the strategy to advance a large-scale, long-life open pit copper mining scenario that leverages Horden Lake’s upgraded resource base.
The updated mineral resource estimate now stands at 37 million tonnes averaging around 1.1% CuEq, divided into an indicated resource of 19.5 million tonnes at 1.17% CuEq and an inferred resource of 17.4 million tonnes at 1.02% CuEq. The team’s detailed assay results, which account for several metals—including copper, nickel, gold, palladium, platinum, silver, and cobalt—indicate a robust deposit with significant continuity and potential for further expansion.
Sentiment on the news is mixed. From a bullish perspective, the extension of the deposit’s strike, the high-grade intersections, and the successful use of advanced EM survey methods all point to a substantial growth potential and clearer delineation of a high-grade, open pit copper project. Conversely, a bearish view may raise concerns over the early stage nature of these drilling results, the challenges in extrapolating shallow mineralization to full-scale production, and the inherent risks of resource expansion in remote locations. Overall, the developments at Horden Lake present a balanced blend of encouraging technical results and typical exploration risks that investors in the sector should monitor closely.
