TIGER GOLD INTERSECTS 82.7 M @ 1.4 G/T AU WITHIN 307.1 M @ 0.7 G/T AU AT TESORITO AND IDENTIFIES VECTOR TOWARD POTENTIAL FEEDER ZONE

Tiger Gold Corp. has released assay results from the third hole of its continuing drill campaign at the Tesorito deposit of its Quinchia gold project in Colombia. The Tesorito campaign forms part of Tiger's broader initial 10,000-metre phase 1 drill program. The Quinchia gold project is located in central Colombia's prolific Mid-Cauca gold belt, approximately 20 kilometres south of Aris Mining's Marmato gold mine and Collective Mining's Guayabales and San Antonio projects.

Highlights:

• TSDH-69 intersected 307.1 metres at 0.7 gram per tonne gold from eight metres downhole, including 82.7 m at 1.4 g/t Au from 190 m, including four m at 3.5 g/t Au, and ended in mineralization.
• Increasing sulphide intensity encountered at depth, providing a vector for a potential feeder zone.
• Two rigs continue infill and extension drilling at Tesorito.
• A third rig is exploration drilling at Dos Quebradas.
• Assays pending from four additional drill holes and will be reported in due course.

The assay results reported in this release, summarized in Table 1, targeted the south-central portion of the Tesorito block model.

Robert Vallis, president and chief executive officer, commented: "Results from Tesorito continue to impress, with TSDH-69 returning 0.7 g/t Au over 307.1 m from near surface, including 1.4 g/t Au over 82.7 m within the core of the system. This broad intercept reinforces both the continuity and the scale of the higher-grade portion of our current model and supports the ongoing infill drilling program. Of particular interest, increasing sulphide intensity and locally elevated chalcopyrite at depth may indicate proximity to a higher-grade feeder structure, providing an additional vector for targeted follow-up drilling."

More results expected shortly as drilling continues at Tesorito and Dos Quebradas

Drilling is continuing with two diamond drill rigs at Tesorito, and additional assay results are anticipated in the coming weeks. A third rig has commenced drilling at Dos Quebradas, executing upon the company's plan to test high-impact targets across the Quinchia gold project.

Tesorito drill program targets resource growth and improved confidence

The Tesorito drill program is designed to improve confidence in the mineral resource and to test margins and depth extensions to expand known mineralization. Drilling includes both stepout and infill components, with infill drilling intended to support upgrading the inferred mineral resource to the indicated category and advance the project toward a prefeasibility or feasibility-level study. A summary of mineral resources and the preliminary economic assessment for the Quinchia gold project is provided below.

TSDH-69 returns strong interval and vectors toward a potential feeder zone

TSDH-69 intersected 307.1 m grading 0.7 g/t Au from 8.0 m downhole to end of hole (315.1 m), including 82.7 m grading 1.4 g/t Au (190 to 272.7 m), including four m grading 3.5 g/t Au (190 to 194 m). The hole intersected a porphyry-style system hosted in porphyritic andesite and intrusive breccia/diorite. The 196- to 306-metre interval (110 m grading 1.0 g/t Au) is interpreted to represent the core porphyry domain, and is characterized by potassic alteration (potassium feldspar plus secondary biotite), A-, B- and M-type vein stockwork, gypsum veinlets with traces of molybdenite and chalcopyrite, and disseminated sulphides (pyrite and chalcopyrite) and magnetite. The hole ended in an altered sedimentary package with elevated gold concentrations starting at approximately 307 m that warrant further investigation.

Of significant interest, trace amounts of chalcopyrite were observed in the upper andesite and locally elevated at depth, which may reflect increasing proximity to a mineralizing feeder structure and support further drilling to test for a potentially higher-grade zone.

Third rig drilling at Dos Quebradas high-priority target

The Dos Quebradas target area is located approximately three kilometres northwest of the Tesorito and Miraflores deposits. Historical drilling at Dos Quebradas comprises 23 diamond drill holes totalling 9,326 m completed between 2011 and 2012. The company has mobilized its third drill rig to Dos Quebradas, and drilling has commenced on an initial 1,000-metre program focused on advancing high-priority targets, strengthening the geological framework, refining the company's exploration model, building upon encouraging fieldwork and modelling completed in the fourth quarter of 2025.

The most recent historical mineral resource estimate for the Dos Quebradas deposit was prepared by Resource Development Associates Inc. with an effective date of Feb. 25, 2020, and reported by LCL Resources Ltd. in accordance with the Joint Ore Reserves Committee Code (2012). The historical estimate consisted of an inferred mineral resource of 20.2 million tonnes at 0.71 g/t Au (for 459,000 ounces of gold) using a 0.5 g/t Au cut-off.

The historical Dos Quebradas estimate was based upon 19 diamond drill holes (8,824 m) drilled on 25-metre section spacing, defining mineralization over an approximately 400-metre-by-300-metre area from surface to an approximately 550-metre depth. Mineralization is hosted within diorite porphyry and intrusive breccias.

This estimate is considered historical and has not been verified by Tiger. A qualified person has not done sufficient work to classify this estimate as current, and Tiger is not treating it as current. Recommended work programs include assaying of historical core to confirm grades, database validation and verification to ensure data integrity, and updated geological modelling to align with current Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves. Tiger considers Dos Quebradas an exploration prospect within the Quinchia gold project, with potential requiring further drilling and evaluation.

Mineral resources and preliminary economic assessment

Quinchia gold project PEA

A preliminary economic assessment and technical report for the Quinchia gold project (effective Sept. 18, 2025) was completed by Ausenco Engineering and filed on SEDAR+ on Dec. 10, 2025.

The PEA base case evaluated the Quinchia gold project's Miraflores and Tesorito deposits at a $2,650 (U.S.)-per-ounce-gold price and $29.51 (U.S.)-per-ounce-silver price using a discounted cash flow analysis at a 5-per-cent discount rate and, based upon the assumptions set out in the technical report, resulted in a posttax net present value (5 per cent) of $534-million (U.S.), an internal rate of return of 21.3 per cent and a payback period of 3.83 years. Over the 10.2-year mine life, the PEA reported average annual payable production of 138,000 oz of gold and 104,000 oz of silver (141,000 oz gold equivalent), with cash costs of $1,199 (U.S.) per oz Au and all-in sustaining costs of $1,340 (U.S.) per oz Au. The PEA also outlined an upside case at $3,700 (U.S.) per oz Au that yielded a posttax net present value (5 per cent) of $1,188-million and an internal rate of return of 36.5 per cent.

The PEA is, by definition, preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA results will be realized.

The technical report includes mineral resource estimates for the Miraflores and Tesorito deposits with an effective date of July 31, 2025. The mineral resources were estimated using CIM Definition Standards for Mineral Resources and Mineral Reserves (2014) and in accordance with CIM Mineral Resources and Mineral Resources Best Practice Guidelines (2019). Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Sampling, quality assurance and quality control

All drill core is logged by a company geologist, photographed and cut in half at the company's core facility in Quinchia, Colombia. One-half of the core is bagged and sent to ALS's laboratory in Medellin for sample preparation and with subsamples sent to ALS's laboratory in Lima, Peru, for analysis, while the other half is retained o nsite as a witness sample. ALS's Medellin and Lima laboratories are ISO/IEC 17025 accredited and are independent of the company. All samples are analyzed for gold using 50-gram fire assay with AAS finish (Au-AA26). Samples are also analyzed for a 48-element suite by ICP-AES and ICP-MS following a four-acid digestion (ME-MS61L). Where applicable, high-grade and overlimit assays are reanalyzed using an appropriate technique. In addition to the laboratory's QA/QC practices, certified reference materials, coarse blanks and duplicates are inserted into the sample stream to monitor analytical performance. Collar co-ordinates are preliminary and were recorded in the field using hand-held GPS. Drill core was oriented, and downhole orientation surveys were collected at regular intervals. Only results that meet Tiger's QA/QC protocols are reported.
