Lodestar Spots Copper Sulphides in Drill Core From Maiden Hole at Three Saints

Why It Matters

The discovery validates Lodestar’s geological model and positions Three Saints as a prospective IOCG target in a world‑class mining district, potentially adding a new copper‑gold resource to the company’s portfolio.

Key Takeaways

• Visible chalcopyrite and magnetite found from 190m to 600m.
• Mineralisation intensity increases with depth in maiden hole.
• IOCG-style signatures align with regional copper‑gold belt.
• Second diamond drill hole planned to test extensions.
• Core sent for multi‑element assays; results expected next quarter.

Pulse Analysis

The Andes of northern Chile host some of the world’s richest copper‑gold systems, from the giant Candelaria mine to the high‑grade Atacama‑Kozan deposit. Within this metallogenic corridor, the Three Saints target sits only 65 km from Lundin Mining’s Candelaria operation, benefitting from similar structural controls and magmatic‑hydrothermal histories. Internationally‑type copper‑gold (IOCG) deposits are prized for their combined metal suite, often delivering robust copper grades alongside by‑product gold and molybdenum. As exploration budgets tighten, projects that can tap into these proven geological templates attract heightened attention from both junior explorers and major miners.

Lodestar’s decision to switch from a shallow reverse‑circulation program to diamond drilling paid immediate dividends, revealing visible chalcopyrite, pyrite, molybdenite and magnetite across a 410‑metre interval. The mineral assemblage mirrors the alteration halos typical of IOCG systems, and the observed increase in sulphide density with depth hints at a vertically extensive ore body. While assay data remain pending, the visual evidence alone strengthens the company’s resource model and justifies expanding the drilling campaign. A second diamond hole, aimed at the projected continuation of the sulphide zone, is slated to commence within weeks.

Assay results, expected in the next quarter, will be the first quantitative test of Three Saints’ grade potential and could catalyse a re‑rating of Lodestar’s valuation. Should the core return copper concentrations comparable to regional benchmarks—0.5 % Cu or higher—the project may quickly move toward a preliminary resource estimate, enhancing the company’s leverage in a market hungry for new supply amid tightening copper demand. Moreover, the proximity to existing infrastructure and the presence of molybdenum and gold as by‑products improve the project's economics, positioning it as a compelling acquisition target for larger mining groups.
