Tocvan posts up to 82.25% gold recovery in Gran Pilar closed-circuit column leach tests

• Tocvan Ventures reported closed-circuit column leach results supporting heap-leach processing at the Gran Pilar gold-silver project in Sonora, Mexico.
• Column tests on a 1,037 kg composite returned 75.36%–82.25% gold extraction, with higher recovery at a finer P80 3/8-inch crush.
• Silver extraction reached 49.12%–57.99% over 77 leach days, implying an Ag:Au ratio near 4.7–5.0.
• Agglomeration did not improve recovery, while increasing NaCN consumption; non-agglomerated columns used 1.08–1.29 kg/t NaCN.
• Results underpin a permitted 50,000-ton heap-leach pilot targeting first production in Q4 2026, improving on a 2023 heap test.
