Vancouver, British Columbia — Tiger Gold Corp. (TSXV: TIGR) (FSE: D150) (OTCQB: TGRGF) (“Tiger” or the “Company”) is pleased to report assay results from its ongoing diamond drilling campaign at the Tesorito deposit at its Quinchía Gold Project in Colombia’s prolific Mid-Cauca gold belt. Drilling at Tesorito forms part of Tiger’s broader 20,000-metre drill program, which is ongoing with three diamond drill rigs active across the project.

“TSDH-80 returned 305.55 m at 0.5 g/t Au at Tesorito below the 2025 Mineral Resource conceptual pit shell, with an 8 m higher-grade interval that may be a continuation of the potential feeder zone we hit in TSDH-71. These results add to our geologic understanding beneath the current resource. We’ll plan additional follow-up once results come in from the next section line north of TSDH-71, which we expect to assist in our evolving interpretation and inform future drilling.”

Drilling results for TSDH-80 are summarized in Tables 1 and 2. Figure 1 shows the location of the reported drillhole. Figure 2 presents a cross section through drillholes TSDH-68 to TSDH-71, TSDH-78, and TSDH-80. Results for these holes were previously reported in Tiger news releases dated January 20, January 29, February 18, February 24, and April 16, 2026. Figure 3 is a map of the Quinchía Gold Project.

TSDH-80 Returns Broad Gold Mineralization and Refines the Feeder Targeting Model

TSDH-80 was collared from the same pad as TSDH-71 (Figure 1) and drilled at a steeper angle than TSDH-71 to reach greater depth and test for the expected continuation of the potential feeder-style structure encountered in TSDH-71 (Figure 2). As reported on February 24, 2026, TSDH-71 returned 89.96 m grading 0.9 g/t Au, including 16.9 m grading 2.3 g/t Au, 0.25% Cu, and 158 ppm Mo, including 6 m grading 4.1 g/t Au, 0.43% Cu, and 302 ppm Mo, which the Company interprets as a potential feeder-style mineralizing event (Table 3).

From surface to approximately 185 m the hole passed through colluvium and basalt, which were not meaningfully mineralized, consistent with the Company’s models. Below that, the hole entered porphyritic andesite that returned 15.7 m grading 1.1 g/t Au and 8 m grading 1.3 g/t Au, 0.16% Cu, and 131 ppm Mo (Table 1) within a broader intercept of 305.55 m grading 0.5 g/t Au from 516 m downhole.

The 305.55 m interval was encountered substantially deeper than the Company had expected based upon its geological model at the time of drilling. The Company interprets this deeper-than-expected starting position to an offset of the mineralized system (Figure 2). The displacement interpretation is supported by TSDH-80’s intersection with Marmato Fault near the bottom of the hole that is still being evaluated.

The 8 m sub-interval is hosted within a deeper sequence of intrusive breccia and early-stage diorite that appears similar to the package that hosts the TSDH-71 potential feeder interval. Its copper and molybdenum grades are several times higher than the average copper and molybdenum grades of composite intervals elsewhere at Tesorito. The Company interprets the 8 m sub-interval as potentially representing the offset continuation of the same potential feeder-style structure encountered in TSDH-71.

Following review and integration of results from the drill section line to the north of TSDH-71, the Company plans to follow up the potential feeder zone target with additional drilling. The Company expects this will assist in its evolving interpretation and inform future drilling.

Drilling of TSDH-80 was affected by a short core-loss interval at approximately 612 m and by the downhole loss of drilling rods, bits, and tools, which together prevented continuation of the parent hole beyond approximately 626 m. A wedge (TSDH-80-W1) was kicked off at approximately 615 m and drilled at an azimuth of N132° and an inclination of -63° to a final depth of 847.7 m. Assay results reported in Table 1 are presented as a continuous run.

Mineral Resources and Technical Report

A report titled Quinchía Gold Project NI 43-101 Technical Report & Preliminary Economic Assessment, Department of Risaralda, Colombia (effective September 18, 2025) (the “Technical Report”) was filed on SEDAR+ on December 10, 2025. The Technical Report also supports the disclosure of Mineral Resource estimates for the Miraflores and Tesorito deposits with an effective date of July 31, 2025. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

Sampling, Quality Assurance and Quality Control

All drilling was completed using HQ- and NQ-diameter diamond core. Drill core is logged by a Company geologist, photographed, and cut in half at the Company’s core facility in Quinchía, Colombia. One half of the core is bagged and sent to ALS’ laboratory in Medellín for sample preparation and with sub-samples sent to ALS’ laboratories in Lima, Perú or North Vancouver, British Columbia for analysis. The remaining half-core (or quarter-core if a duplicate sample was taken) is retained onsite as a witness sample. ALS’ Medellín, Lima, and North Vancouver laboratories are ISO/IEC 17025 accredited and are independent of the Company. All samples are analyzed for gold using 50 g 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 re-analyzed using an appropriate technique. In addition to the laboratory’s QA/QC practices, certified reference materials, coarse blanks, and quarter-core duplicates are inserted into the sample stream to monitor analytical performance. Other than as reported in this news release, no unreported significant core recovery or drilling issues were encountered during the program. Collar coordinates are preliminary and were recorded in the field using handheld GPS with elevation derived from a 2025 airborne LiDAR survey. Drill core was orientated, and downhole orientation surveys were collected at regular intervals. Only results that meet Tiger’s QA/QC protocols are reported.
