Tintina Mines (TNNTF) reported an initial drill intercept of 460m at 0.50% copper equivalent (CuEq) at its wholly owned Dos Amigos project in Chile. Hole SDDK26-001 returned 0.31% copper and 0.24 g/t gold from 200m depth to its 660m end. Included intervals were 112m at 0.55% CuEq, 26m at 0.41%, 98m at 0.63% and 166m at 0.50%.
The program aims to convert Inferred mineral resources to the higher-confidence Indicated category for a planned feasibility study. Tintina said grades correspond well with its 2026 preliminary economic assessment model, with approximately 0.50% CuEq at the pit base where low grades had been interpreted. Three rigs operate around the clock, with a fourth arriving imminently. The company plans to extend selected holes at depth to test vertical continuity. Drilling costs and performance are tracking in line with budget; further samples are undergoing laboratory analysis.
Tintina Mines (TNNTF) has commenced an initial 40,000-metre diamond drilling program at its wholly owned Dos Amigos copper-gold project in Chile.
The program is designed to convert existing Inferred Mineral Resources to the Indicated category to support future feasibility study work. Current Mineral Resources, supporting the 2026 PEA, comprise 100.8 Mt Measured & Indicated at 0.35% Cu and 0.28 g/t Au, and 256.3 Mt Inferred at 0.34% Cu and 0.24 g/t Au, reported within a conceptual open pit at a 0.2% total Cu cut-off.
Drilling will ramp up to as many as six rigs operating 24 hours per day in Q4 2026 through Q2 2027, with initial assays expected mid-November and an updated Mineral Resource Estimate targeted for H2 2027. The Tricolor porphyry target ~3 km north of Dos Amigos will be drill tested in Q4 2026 following a 2018 hole that returned 230 m at 0.56% Cu and 0.33 g/t Au. Tintina also announced the appointment of Richard Leclerc as General Manager of its Chilean subsidiary and engaged Target IR for investor relations services.
