Costa Fuego comprises the Cortadera, Productora, Alice and San Antonio deposits and is regarded as one of the better undeveloped copper resources globally. It has a mammoth combined resource of 798 million tonnes grading 0.45 per cent copper equivalent, for 2.9 million tonnes of copper, 2.6 million ounces of gold, 12.9m ounces of silver and 68,000t of molybdenum.
Geologically, Cortadera and Alice fit the mould as classic copper-gold-molybdenum porphyry systems, while San Antonio is interpreted as a lode-style copper skarn – the kind of mineralisation commonly developed on the fringes of intrusive bodies and porphyry centres.
Rounding out the suite, Productora is thought to be a tourmaline-breccia hosted copper-gold-molybdenum system, adding yet another layer of geological diversity to the district.
The company believes its Costa Fuego project is a global standout among a limited number of independent, large-scale copper operations nearing development, with strong exposure to rising prices.
Impact modelling by Hot Chili suggests La Verde could add significant open-pit material to the front end of Costa Fuego’s proposed 20-year mine schedule, potentially extending mine life and materially improving the financial metrics outlined in Hot Chili’s March 2025 pre-feasibility study.
The timing of these results could hardly be better after copper prices reached all-time highs of US$6.15 (A$9.20) a pound at the start of the week, notching up a stellar 53 per cent rise in the past 12 months alone.
Long-term consensus prices now sit at around US$4.51 per pound for copper and US$3,137 per ounce for gold — both well above the assumptions used in the pre-feasibility study — meaning any additional near-surface tonnes could deliver outsized value.
As drilling continues to target extensions to the high-grade core as well as lateral and strike growth, punters can expect further news flow in the near term.
Consistent thick intercepts, shallow mineralisation and substantial leverage to buoyant copper and gold markets all point to La Verde fast shaping up as a compelling growth engine within Hot Chili’s broader Costa Fuego development strategy.
