Tintina Mines Announces Commencement of Drilling at the Dos Amigos Project in Chile
Tintina ramps up drilling at Dos Amigos to target resource conversion ahead of its scheduled 2027 resource update.
Tintina Mines Ltd. (TTS) has officially commenced a 40,000-meter diamond drilling program at its Dos Amigos project in Chile. The initiative aims to convert Inferred Mineral Resources to the Indicated category to support future feasibility studies and a targeted Final Investment Decision (FID) in 2030.
Drilling activity will ramp up over the next month, with up to six rigs operating 24/7 through the second quarter of 2027. Initial assay results are expected in mid-November 2026, while an updated Mineral Resource Estimate is targeted for the second half of 2027. The primary focus of the program is the Dos Amigos target, located between 300m and 800m in depth. Shallower drilling will be conducted at Marisol, with high-priority porphyry testing scheduled at the Tricolor target in the fourth quarter of 2026.
In secondary corporate updates, Tintina Mines has appointed Richard Leclerc as General Manager for its Chilean subsidiary. The company has also engaged an investor relations firm for a fee of CAD$9,000 per month.
Tintina Mines Ltd. (TTS) has commenced drilling, marking the direct execution of the work program announced alongside its C$91 million private placement in August 2026. The company had explicitly stated that drilling was expected to commence by the end of September 2026.
This update confirms that the company is on schedule to upgrade its resource base, a critical step for advancing the project toward a feasibility study and final investment decision.
Tintina Mines Ltd. (TTS) is a Canadian junior explorer focused on the Dos Amigos (formerly Domeyko Sulfuros) copper-gold project in the Atacama region of northern Chile. The project is a brownfield site with prior oxide operations and exposed sulphide mineralization.
According to Mineral Resources reported by SRK Consulting in January 2026, the project holds 100.8 Mt Measured & Indicated at 0.35% Cu and 0.28 g/t Au, alongside 256.3 Mt Inferred at 0.34% Cu and 0.24 g/t Au.
The Preliminary Economic Assessment (PEA) outlines a 25-year open-pit operation at 35,000 tpd, targeting approximately 37kt Cu/yr and 57koz Au/yr. The assessment projects a pre-tax NPV of $560M USD and a 26-year mine life. The project features a 100% renewable energy strategy and raw seawater processing to address environmental constraints.
