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. The results include two of the strongest gold intersections drilled to date by Tiger at the Tesorito deposit. Drilling is ongoing with two diamond drill rigs at Ceibal and one at Tesorito.

Highlights:

• TSDH-88 intersected 234.54 m @ 1.2 g/t Au from 2 m downhole
  • including 27.6 m @ 1.8 g/t Au
  • including 26.57 m @ 2.3 g/t Au
  • including 22 m @ 1.5 g/t Au
• TSDH-87 intersected 180.3 m @ 1.0 g/t Au from surface
  • including 66.5 m @ 1.3 g/t Au
• Additional assays are pending from Tesorito and Ceibal

Robert Vallis, President & CEO, commented, “TSDH-87 and TSDH-88 are among the best holes we have drilled at Tesorito, each returning long composite intervals at grades more than double the 0.47 g/t Au average grade of the deposit’s Inferred Mineral Resource. Together with TSDH-86, they define a coherent, higher-grade corridor of intrusive-hosted gold mineralization. These infill results will feed directly into our year-end Mineral Resource update for Tesorito, which is aimed at converting a significant portion of the resource to Indicated, and will inform 2027 engineering studies.”

The results reported in this news release are summarized in Tables 1 and 2. Figure 1 shows the drillhole collar and section locations and Figure 2 presents a cross section through the reported holes. Figure 3 is a regional map of the Quinchía Gold Project.

TSDH-87 and TSDH-88 are infill holes drilled on the same section line as TSDH-86, which was reported on June 4, 2026 and lies at the southeastern end of the line (Figure 2). TSDH-86 returned 98 metres grading 0.9 g/t Au from 2 metres downhole, including 26.7 metres grading 1.6 g/t Au, and ended in mineralization.

TSDH-88 Returns 234.54 m @ 1.2 g/t Au from Near Surface

TSDH-88 intersected 234.54 metres grading 1.2 g/t Au from 2 metres downhole, as detailed in Table 1. The interval includes 27.6 metres grading 1.8 g/t Au, 26.57 metres grading 2.3 g/t Au, and 22 metres grading 1.5 g/t Au.

Mineralization is hosted within a broad early diorite body and an underlying porphyritic andesite extending from approximately 44 metres downhole to the base of the hole. Logging identified weak to moderate potassic alteration overprinted by strong chlorite-sericite. A well-developed B-type quartz-sulphide stockwork is present, together with M-type magnetite veins locally reaching densities of up to 8 veinlets per metre. Within potassic-altered intervals, disseminated sulphides are visually estimated at up to approximately 1% pyrite, 0.3% chalcopyrite, and 0.2% molybdenite by volume. The strongest mineralization is hosted in strongly altered intrusive rock below the near-surface saprolite. Vein density and sulphide content increase through the central part of the hole. The Company interprets this as reflecting increasing proximity to a more intensely mineralized part of the porphyry system. Near its base, the hole passed into a sedimentary sequence at the Marmato Fault contact and ended at 256.6 metres.

TSDH-87 Intersects 180.3 m @ 1.0 g/t Au and a Mineralized Intrusive Breccia

TSDH-87, drilled between TSDH-86 and TSDH-88 on the same section line (Figure 2), intersected 180.3 metres grading 1.0 g/t Au from surface, including 66.5 metres grading 1.3 g/t Au, as detailed in Table 1.

The hole intersected a multiphase early diorite complex and a mineralized early-diorite intrusive breccia between approximately 47.5 metres and 83.1 metres. Within and adjacent to the breccia, logging identified moderate to strong chlorite-sericite overprinting the potassic alteration with secondary biotite and potassium feldspar. Chalcopyrite is visually estimated at approximately 0.1-0.2% and pyrite at 0.4-0.8%. The same interval carries a high-temperature vein assemblage, including A-type, B-type, M-type and unidirectional solidification texture veins up to 8 veinlets per metre. Potassic alteration is developed near-continuously over more than 115 metres, from approximately 48 metres to 166 metres. Within it, B-type quartz-sulphide veinlets locally reach up to six veinlets per metre and carry chalcopyrite, pyrite, magnetite and local molybdenum.

The Company interprets the intrusive breccia and high-temperature vein assemblage as evidence of proximity to a potential fertile intrusive centre. Below approximately 166 metres downhole, the hole passed into a sedimentary sequence at the Marmato Fault contact and ended at 180.3 metres.

In both holes, the near-surface portion of the mineralization is developed within supergene-altered saprolite and may in part reflect supergene enrichment. Such near-surface grades are not necessarily representative of primary mineralization at depth.

TSDH-86, TSDH-87 and TSDH-88 Define a Coherent Higher-Grade Corridor

TSDH-86, TSDH-87, and TSDH-88 together define a coherent, broadly mineralized interval through this part of the Tesorito deposit. They include among the highest-grade intervals drilled to date by Tiger at Tesorito.

The Company interprets the mineralization along this section as broadly developed across multiple intrusive phases and breccias, rather than confined to a single structure. Drilling indicates the mineralized corridor remains open to the northwest and at depth. TSDH-89, drilled further along the section to the northwest, has been completed and assays are pending.

The early diorite intersected in TSDH-87 and TSDH-88, finer-grained and characterized by chlorite-sericite alteration overprinting a potassic core, with B-type quartz-sulphide and M-type magnetite veinlets, is texturally and mineralogically distinct from the equigranular early diorite intersected in TSDH-71, interpreted as a potential feeder, which preserves strong, overprinted potassic alteration and A-type veins with chalcopyrite. This contrast is interpreted as evidence that the early diorite intrusive event at Tesorito was polyphase and temporally protracted, with an earlier, higher-temperature pulse represented by the interpreted feeder in TSDH-71 and successive, slightly cooler pulses recorded in TSDH-87 and TSDH-88.

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) 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. A qualified person has verified the data underlying the disclosure in this news release, including the sampling, analytical, and test data, by reviewing the original ALS assay certificates against the Company’s drillhole database and reviewing the associated quality assurance and quality control results. No limitations on, or failures of, the verification process were identified, and the qualified persons are not aware of any drilling, sampling, recovery, or other factors that could materially affect the accuracy or reliability of the data, other than as disclosed in this news release. 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.
