Tiger Gold Intersects 169.7 m at 0.9 g/t Au of Porphyry-Style Mineralization at Tesorito, Including 25 m at 2.2 g/t Au

April 16, 2026 | ArcStone Financial Pulse

Overview

Tiger Gold Corp. (TSXV: TIGR | OTCQB: TGRGF | FSE: D150) announced assay results from six diamond drillholes at its flagship Tesorito porphyry gold-copper deposit, part of the Quinchía Gold Project in Colombia’s Mid-Cauca gold belt. The headline hole, TSDH-78, returned 169.7 metres grading 0.9 g/t Au, including a higher-grade sub-interval of 25 metres at 2.2 g/t Au with 206 ppm Mo. The company stated the hole supports the continuity of higher-grade mineralization in this part of the deposit and provides additional geological context for the potential feeder-style zone first identified in TSDH-71.

The new holes were completed as part of Tiger Gold’s ongoing 20,000-metre drill program, with three diamond drill rigs currently active across the project.

Key Highlights

• TSDH-78: 169.7 metres at 0.9 g/t Au from 278.29 m to 448 m, including 25 m at 2.2 g/t Au with 206 ppm Mo, 17.1 m at 1.5 g/t Au, and 10 m at 1.4 g/t Au. True width 138.0 m.
• TSDH-75: 64 m at 0.3 g/t Au (true width 54.7 m) and 72.9 m at 0.5 g/t Au (true width 62.1 m).
• TSDH-76: 147 m at 0.3 g/t Au (true width 125.7 m) from 66 m depth.
• TSDH-77: 171.35 m at 0.3 g/t Au (true width 146.7 m) from 8 m depth, interpreted by the company as defining the near-surface lateral limit of stronger porphyry development in this part of the deposit.
• TSDH-79: 22 m at 0.3 g/t Au and 10 m at 0.2 g/t Au.
• TSDH-81: 47 m at 0.3 g/t Au and 24.8 m at 0.4 g/t Au.

Geological Context

According to the company, the higher-grade portion of TSDH-78 begins where the hole enters a more complex intrusive-dominated sequence within the broader Tesorito porphyry system. The strongest part of the interval is associated with intrusive breccias and diorite pulses, together with chlorite-sericite-magnetite alteration overprinting earlier potassic alteration. The system hosts A-, B-, and M-type porphyry veinlets with chalcopyrite and molybdenite associations.

TSDH-78 is positioned to test geological continuity relative to TSDH-71, a previously reported hole that returned 89.96 m at 0.9 g/t Au, including 16.9 m at 2.3 g/t Au, 0.25% Cu, and 158 ppm Mo, and 6 m at 4.1 g/t Au, 0.43% Cu, and 302 ppm Mo.

Management Commentary

Robert Vallis, President and Chief Executive Officer, commented: “TSDH-78 is another strong result from one of the strongest sections drilled at Tesorito to date and further supports the continuity of higher-grade mineralization in this part of the deposit. Together with the other holes drilled, we continue to improve our understanding of the Tesorito system and help define the extent of mineralization in this area. TSDH-78 also provides important geological information in relation to the potential feeder-style mineralization identified in TSDH-71, and we now look forward to receiving assays from TSDH-80, which was drilled to test the expected continuation of that zone below TSDH-71.”

Project Context

The Quinchía Gold Project is located in the Department of Risaralda, Colombia, within the Mid-Cauca gold belt. The project hosts two defined deposits, Miraflores and Tesorito, each with Mineral Resource estimates effective July 31, 2025, and additional exploration targets at Dos Quebradas and Ceibal. Tiger holds an option to acquire a 100% interest in the project. The most recent NI 43-101 Technical Report and Preliminary Economic Assessment has an effective date of September 18, 2025, and was filed on SEDAR+ on December 10, 2025.

What to Watch Next

• Assay results from TSDH-80, drilled to test the expected continuation of the potential feeder-style mineralization identified below TSDH-71.
• Additional pending assay results from ongoing drilling at Tesorito, Dos Quebradas, and Ceibal.
• Continued execution of the 20,000-metre drill program across the three active rigs.

QA/QC

Per the company’s release, all drill core is logged by a company geologist, photographed, and cut in half at Tiger’s core facility in Quinchía. One half is bagged and sent to ALS’ laboratory in Medellín for sample preparation, with sub-samples sent to ALS’ laboratories in Lima, Perú or North Vancouver, British Columbia for analysis. Gold is analyzed by 50 g fire assay with AAS finish (Au-AA26), and samples are also analyzed for a 48-element suite by ICP-AES and ICP-MS following a four-acid digestion (ME-MS61L). ALS’ Medellín, Lima, and North Vancouver laboratories are ISO/IEC 17025 accredited and independent of the company. Certified reference materials, coarse blanks, and quarter-core duplicates are inserted into the sample stream to monitor analytical performance.

The technical disclosure in the release was reviewed and approved by Jeremy Link, M.Eng., P.Eng., Tiger’s Vice-President, Corporate Development, and César García, M.Sc., FAusIMM, the company’s Exploration Manager in Colombia, each a qualified person as defined by NI 43-101.
