Tintina Mines Raises Major Funding for Chilean Copper-Gold Development
Copper-focused junior mining company Tintina Mines has secured C$91 million (approximately US$65.8 million) in new financing to support the development of its flagship Domeyko Sulfuros copper-gold project in Chile and consolidate ownership of the asset.
The financing is backed by Japan’s Sumitomo Corporation and the Gignac family, providing a significant boost to the company’s efforts to advance the project toward production.
Financing Structure
According to the company, the funding will be raised through a private placement of subscription receipts priced at C$0.68 per receipt.
The offering will be completed in two separate tranches:
First tranche: C$62 million, consisting of common shares and warrants.
Second tranche: C$29 million, consisting solely of common shares.
Tintina stated that approximately C$55 million of the proceeds will be allocated toward advancing Domeyko Sulfuros to a Final Investment Decision (FID), while the remaining C$36 million will be used to acquire the project’s minority shareholders, who currently own 26.25% of the asset.
Following the transaction, the implied pre-money valuation of the Domeyko Sulfuros project is estimated at approximately C$138 million.
Significant Copper and Gold Resources
Located in Chile’s Atacama Region, Domeyko Sulfuros is a brownfield copper-gold porphyry project situated in an area that previously hosted oxide mining operations.
Current measured and indicated resources are estimated at:
- 100.8 million tonnes
- Copper grade: 0.35%
- Gold grade: 0.28 g/t
Inferred resources are estimated at:
- 256.3 million tonnes
- Copper grade: 0.34%
- Gold grade: 0.24 g/t
These resource estimates position Domeyko Sulfuros as a sizeable copper-gold development opportunity within one of the world’s most important mining jurisdictions.
Development Plan
Earlier this year, Tintina Mines released a Preliminary Economic Assessment (PEA) outlining a potential 25-year open-pit mining operation.
Under the proposed development scenario, the project could produce annually:
- Approximately 37,000 tonnes of copper
- Approximately 57,000 ounces of gold
The project is expected to generate copper and gold concentrates for sale into global markets.
Strategic Support from Investors
Mathieu Gignac, President of G Mining Services, described Domeyko Sulfuros as the type of copper-gold opportunity the Gignac family actively seeks.
He emphasized that the project combines meaningful scale with a manageable level of technical complexity, making it suitable for successful financing, construction, development, and long-term operation.
Growing Interest in Copper Projects
The financing reflects continued investor confidence in copper development projects as global demand expectations strengthen.
Copper remains one of the most strategically important metals for electrification, renewable energy infrastructure, power transmission networks, electric vehicles, and artificial intelligence-related data center expansion.
As supply growth remains constrained globally, well-defined projects in established mining jurisdictions such as Chile continue to attract significant investment from strategic partners and institutional investors.
With fresh capital secured and ownership consolidation underway, Tintina Mines is positioning Domeyko Sulfuros as a future contributor to global copper and gold supply.
