Tiger Gold Corp. (TSX-V: TIGR) (FSE: D150) (OTCQB: TGRGF) is pleased to report assay results from its ongoing diamond drilling campaign at its Quinchía Gold Project in Colombia’s prolific Mid-Cauca gold belt. Tiger has completed more than 11,350 m of drilling in over 35 holes across the project as part of its broader 20,000-metre drill program. The program is ongoing with three diamond drill rigs, including one rig at Tesorito and two at Ceibal.

Highlights:

• TSDH-86 intersected 98 m @ 0.9 g/t Au from 2 m downhole and ended in mineralization
  • including 26.7 m @ 1.6 g/t Au
• TSDH-85 intersected 205.5 m @ 0.5 g/t Au from 184 m downhole
  • including 8 m @ 1.7 g/t Au
  • including 10 m @ 1.2 g/t Au
• TSDH-84 intersected 127.4 m @ 0.5 g/t Au from 2.6 m downhole
• TSDH-83 intersected 42 m @ 0.5 g/t Au from 2 m downhole
• QDQDH-26 returned 254 m @ 0.4 g/t Au from 2 m downhole, completing Tiger’s initial three-hole drill program at Dos Quebradas
• Additional assay results are pending from drillholes at Tesorito and Ceibal

Robert Vallis, President & CEO, commented, “Our team continues to execute across multiple fronts at the Quinchía project. At Tesorito, drilling continues to define a large, coherent gold-dominant porphyry system. The results will support a year-end Mineral Resource update aimed at converting a significant portion of the current resource to Indicated and will inform the next phase of engineering studies in 2027.”

The results reported in this news release are summarized in Tables 1 and 2. Figures 1 through 4 show the Tesorito drillhole and cross section locations. Figures 5 and 6 show the Dos Quebradas drillhole and cross section locations. Figure 7 is a regional map of the Quinchía Gold Project.

TSDH-85 Completes a Six-Hole Section Line with 205.5 m @ 0.5 g/t Au

TSDH-85 intersected 205.5 m grading 0.5 g/t Au from 184 m downhole, including 8 m grading 1.7 g/t Au and 10 m grading 1.2 g/t Au, as detailed in Table 1. TSDH-85 is an infill hole drilled on the northwestern part of a section line that also includes TSDH-72, TSDH-73, TSDH-74, TSDH-75, and TSDH-79 (Figure 2). Mineralization is hosted within porphyritic andesite intruded by diorite and associated magmatic breccia. Logging identified widespread chlorite-sericite alteration overprinting local potassic alteration, together with abundant B-type quartz veinlets, D-type veinlets, and locally chalcopyrite- and molybdenum-bearing veinlets, consistent with a mineralized porphyry environment. The mineralized interval continues to a basalt contact near the base of the hole.

The prior results shown in Figure 2 were reported on February 18 and April 16, 2026. Together, these six holes outline a broadly mineralized section through this part of the Tesorito deposit and provide useful control for future resource modelling.

TSDH-86 Intersects 98 m @ 0.9 g/t Au Near Conceptual Pit Margins

TSDH-86 was drilled to test near-surface gold mineralization along the northeastern margin of the current Mineral Resource conceptual pit shell (Figure 4). The hole intersected 98 m grading 0.9 g/t Au from 2 m downhole, including 26.7 m grading 1.6 g/t Au from 3.3 m, and ended in mineralization at the 100 m end of hole, as detailed in Table 1.

Mineralization is hosted primarily within early diorite and porphyritic andesite units affected by potassic alteration and abundant B-type quartz veinlets, locally accompanied by M-type and D-type veining. Logging also identified chalcopyrite and molybdenum-bearing veinlets and fractures, supporting the interpretation of a large-scale gold-dominant porphyry hydrothermal system The near-surface higher-grade interval is developed within supergene-altered saprolite and may in part reflect supergene enrichment, and such near-surface grades are not necessarily representative of primary mineralization at depth.

TSDH-86 is the first hole reported from this section line and lies at its southeastern end. Three further holes, TSDH-87, TSDH-88, and TSDH-89, have been drilled to the northwest along the same line. The traces of these holes are shown in Figure 4.

TSDH-84 and TSDH-83 Infill and Extension Drilling Returns 127.4 m @ 0.5 g/t Au

TSDH-84 was drilled as an infill hole on the section line that also includes TSDH-67, while TSDH-83 was drilled to test the deposit margin along that line (Figure 3). TSDH-83 replaces TSDH-82, which was collared nearby but abandoned at 26.1 m due to drilling difficulties.

TSDH-84 intersected 127.4 m grading 0.5 g/t Au from 2.6 m downhole, hosted within multiple diorite phases and intrusive breccias carrying strong potassic alteration, abundant B-type quartz-feldspar veinlets, and locally chalcopyrite and molybdenum mineralization. Magmatic breccia and porphyry-style vein assemblages may indicate proximity to a potential near-surface fertile intrusive centre. Further southeast, TSDH-83 intersected 42 m grading 0.5 g/t Au from 2 m downhole, with mineralization developed near surface within saprolite. The hole then passed into porphyritic andesite and a late diorite intrusion with porphyry-style veining and alteration before reaching the contact with the Marmato Fault and entering a sedimentary sequence. Both intervals are detailed in Table 1.

The prior results for TSDH-67 shown in Figure 3 were reported on January 20, 2026. Together, these three holes outline a broadly mineralized section through this part of the Tesorito deposit and provide useful control for future resource modelling while also improving the geological understanding of the porphyry-related system.

Tiger has completed more than 6,625 m of drilling over 26 holes have been completed at Tesorito. Tiger plans to complete up to approximately 5,360 of additional infill, gap. and extension program at Tesorito that is intended to support upgrading a significant portion of the current Inferred Mineral Resource to the Indicated category.

QDQDH-26 Returns 254 m @ 0.4 g/t Au at Dos Quebradas

At the Dos Quebradas prospect, QDQDH-26 completes the reporting of results from the Company’s initial three-hole drill program. Results from QDQDH-25 and QDQDH-27 were reported on April 21, 2026. QDQDH-26 was drilled to 343.1 m and intersected 254 m grading 0.4 g/t Au from 2 m downhole, as detailed in Table 1.

QDQDH-26 was collared into a sequence of inter-mineral magmatic breccia and early diorite over the uppermost approximately 66 m, before entering a thick basalt sequence cut by further intervals of magmatic breccia and, below approximately 224 m, intra-mineral diorite. Gold mineralization within the reported interval is associated with the magmatic breccia and diorite phases, together with quartz-magnetite and B-type veining. The host rocks show a porphyry-style alteration framework dominated by chlorite-sericite alteration, with locally preserved earlier biotite-magnetite assemblages, consistent with the porphyry-style framework described in Tiger’s news release dated April 21, 2026.

QDQDH-26 lies on the same section line as QDQDH-27 (Figure 6), which returned 282.45 m grading 0.6 g/t Au from 18 m downhole, including 32 m grading 1.3 g/t Au and 21.23 m grading 1.6 g/t Au. Together, the two holes indicate that gold mineralization at Dos Quebradas is developed across the section, with grade varying between them. Tiger has completed 1,274.65 m of drilling over 3 holes at Dos Quebradas. Figure 6 presents an updated interpretation incorporating the QDQDH-26 results.

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, cut in half, and sampled at the Company’s core facility in Quinchía, Colombia under the supervision of a geologist. 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 core 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.
