Chilean copper hotspot heats up as Hot Chili neighbour banks $91M

The age-old junior explorers’ term “nearology” is typically used to describe a project’s geological potential based on its proximity to another promising discovery.

Every now and then, however, nearology takes on a completely different meaning. Sometimes it becomes a powerful indicator of where serious money is about to flow.

That appears to be exactly what is unfolding in Chile’s emerging Huasco Valley copper district.

Hot Chili’s immediate neighbour, Tintina Mines, has unveiled a hefty C$91million (A$91M) private placement backed by some of the mining industry’s biggest names, including Japanese conglomerate Sumitomo Corporation, the influential Gignac family and royalty giant Franco-Nevada.

The funding package is designed to fast-track development of Tintina’s Domeyko Sulfuros copper-gold project, consolidate full ownership of the asset and push it towards a final investment decision.

Under the deal, Sumitomo and the Gignac family will anchor approximately $48M of the raising through a newly formed investment vehicle, while Franco-Nevada will chip in a further $14M. The broader investor syndicate will provide the balance.

For Tintina, the transaction is transformational.

The company’s Domeyko Sulfuros project hosts a measured and indicated resource of 101 million tonnes grading 0.51 per cent copper equivalent, plus an additional inferred resource of 266 million tonnes at 0.48 per cent copper equivalent.

A preliminary economic assessment outlined a large-scale open-pit operation capable of producing 79,000 tonnes of copper equivalent annually during its first 14 years.

The market has already rewarded the project with a market capitalisation of about $600 million.

For Hot Chili shareholders though, the interesting part sits next door.

Domeyko Sulfuros is effectively surrounded by the company’s flagship Costa Fuego copper-gold development, which boasts a substantially larger resource inventory and a more advanced development profile.

Costa Fuego currently hosts a measured and indicated resource of 798 million tonnes grading 0.45 per cent copper equivalent and a further inferred resource of 203 million tonnes grading 0.31 per cent copper equivalent. Impressively, about 85 per cent of the contained metal already sits in the higher-confidence measured and indicated categories.

The project has progressed beyond the preliminary economic assessment stage and is now sitting at an optimised pre-feasibility study level. It carries a post-tax net present value of US$1.2 (A$1.6) billion at copper levels far below the current all-time highs.

That’s nearly four times larger than Domeyko Sulfuros’ US$328 (A$502) million valuation, despite requiring almost identical upfront capital expenditure of about US$1.27 (A$1.78) billion.

Costa Fuego is also expected to produce about 116,000 tonnes of copper equivalent annually during its first 14 years, significantly higher than its neighbour, while targeting first production in 2030 - two years ahead of Domeyko Sulfuros.

Adding further weight to Hot Chili’s investment case is the company’s rapidly emerging La Verde discovery.

Positioned on the opposite side of Tintina’s ground from the main Costa Fuego deposits, La Verde is shaping up as a potentially highly valuable starter pit opportunity, capable of delivering higher-grade material early in the mine life.

Recent drilling has delivered some eye-catching intercepts, including a remarkable 725-metre hit grading 0.42 per cent copper equivalent from just 18 metres depth, with higher-grade zones returning 22m at 0.71 per cent copper equivalent and 62m at 1.03 per cent copper equivalent. The company is targeting a maiden resource estimate for La Verde next year.

Importantly, Hot Chili already has access agreements in place for key infrastructure, including seawater and power, while port discussions have advanced through a memorandum of understanding. Those advantages have helped streamline development timelines.

The significance of Tintina’s funding success extends beyond the project itself.

When global mining groups, royalty companies and development specialists start writing cheques of this magnitude into a relatively young copper district, it tends to validate the broader region.

For Hot Chili, the arrival of deep-pocketed strategic investors next door appears to be another sign that the Huasco Valley is rapidly emerging as one of South America’s most important undeveloped copper districts.

And with Costa Fuego already bigger, more advanced and potentially on track for earlier production than its newly funded neighbour, the spotlight now appears firmly fixed on Hot Chili’s side of the fence.
