Tiger Gold Corp. (TSX-V: TIGR) (FSE: D150) (OTCQB: TGRGF) is pleased to report assay results for three step-out drillholes from its Ceibal target at its Quinchía Gold Project in Colombia’s prolific Mid-Cauca gold belt.

Highlights:

• CEDDH-014, a 192-metre northwest step out from CEDDH-013, intersected 78.63 m @ 0.8 g/t Au from 204 m downhole
  • including 25.56 m @ 1.4 g/t Au from 232 m downhole
• CEDDH-014 also intersected 86 m @ 0.5 g/t Au from 296 m downhole
  • including 10 m @ 1.5 g/t Au from 326 m downhole
  • including 9.55 m @ 1.3 g/t Au from 308 m downhole
• CEDDH-016, a 235-metre northwest step-out from CEDDH-013, intersected 34 m @ 0.5 g/t Au from 10 m downhole, testing the interpreted northwestern margin of the system
  • including 6 m @ 2.1 g/t Au from 14 m downhole
• CEDDH-015, a 210-metre southeast step-out from CEDDH-003, intersected 14 m @ 0.2 g/t Au from 74 m downhole and did not extend the corridor to the southeast at the position tested
• One drill rig is active at Ceibal and two are completing infill, extension, and gap drilling at Tesorito; assays are pending from both, and a fourth rig is on order

“I am excited about what CEDDH-014 has shown us at Ceibal. It extended gold mineralization further to the northwest, and these holes are doing exactly what large step-out drilling should be doing at this stage – showing us where the higher-grade portions of the system sit, where its margins might be, and where it remains open,” commented Robert Vallis, President and CEO. “That is the information we need to focus the drilling that will support a maiden Mineral Resource estimate for Ceibal that we are targeting for the first quarter of 2027.”

The results reported in this news release are summarized in Tables 1 and 2. Figure 1 shows the Ceibal drillhole collar and section locations. Figures 2, 3, and 4 show the interpretive cross-sections for CEDDH-014, CEDDH-016, and CEDDH-015, respectively. Figure 5 is a regional map of the Quinchía Gold Project. All reported intervals are downhole core lengths. Due to the early stage of exploration, true widths are unknown.

Ceibal lies approximately 1 kilometre south of the Miraflores deposit and 1 kilometre southwest of the Tesorito deposit, within the Marmato Fault Corridor (Figure 5). Tiger’s ongoing approximately 20,000-metre drill program at Ceibal is intended to support a maiden Mineral Resource estimate in the first quarter of 2027. There is no certainty that a Mineral Resource estimate will be defined at the Ceibal target.

Drilling at Ceibal has outlined a northwest to north trending mineralized corridor that is interpreted to be sub-vertical, with an indeterminate dip direction. The apparent width of the corridor is not well constrained by drilling, and further drilling is required. The geometry, true thickness, extent, continuity, orientation, and dip direction of the mineralized system have not been defined at this early stage of exploration. To help resolve the orientation and dip of the corridor, and to test the extent of mineralization across strike, the Company has drilled a pair of offset scissor holes (CEDDH-020 and CEDDH-021) across the corridor, and assays are pending.

Mineralization remains open to the southwest and, in the central part of the corridor, across its apparent strike. The extent of mineralization to the north and north-northeast has not been tested. CEDDH-015 did not intersect intrusive units and did not reach the modelled porphyry-basalt contact, and the southeastern limit of the corridor therefore remains undefined between CEDDH-003 and CEDDH-015, although it appears limited. Mineralization has been traced to approximately 800 metres vertically below surface in previous drilling and remains open at depth.

CEDDH-014 Extended the Corridor Towards the Northwest

CEDDH-014 was drilled to test the northwestern extension of the Ceibal mineralized corridor, approximately 192 metres northwest of CEDDH-013 and 55 metres from CEDDH-016 (Figures 1 and 2). The hole was collared close to the modelled contact between dacite-andesite porphyry to the southwest and basalt to the northeast and was drilled southwest along the dip of that contact, remaining within the porphyry over its entire length.

CEDDH-014 intersected 78.63 metres grading 0.8 g/t Au from 204 metres downhole, including 25.56 metres grading 1.4 g/t Au from 232 metres and 6 metres grading 1.2 g/t Au from 220 metres, and a further 86 metres grading 0.5 g/t Au from 296 metres, including 10 metres grading 1.5 g/t Au from 326 metres and 9.55 metres grading 1.3 g/t Au from 308 metres. The two composites are hosted in dacite-andesite porphyry and are separated by a 10.92-metre barren late diorite dike, the same relationship recorded for the central dike in CEDDH-010. Two lower-grade intervals were intersected above, 10 metres grading 0.3 g/t Au from 58 metres and 50 metres grading 0.2 g/t Au from 106 metres.

Molybdenum broadly tracks gold through the mineralized interval, while copper is present only in trace amounts, low relative to the central holes at Ceibal. Below approximately 382 metres, the hole passed into a zone of elevated base metals and silver, interpreted as a carbonate-base-metal (CBM) assemblage developed in the propylitic halo of the porphyry system, a style typically formed peripheral to gold-bearing porphyry centres, and equivalent to the sphalerite-galena veinlets logged in CEDDH-011 and CEDDH-012.

CEDDH-016 Tested a Further Northwestern Extension of the Ceibal System

CEDDH-016 was drilled to test a further northwesterly extension of the Ceibal system, approximately 235 metres northwest of CEDDH-013 and 55 metres northwest of CEDDH-014, at the northwestern extent of the current drill pattern (Figures 1 and 3). Within the porphyry, the drillhole intersected 34 metres grading 0.5 g/t Au from 10 metres downhole, including 6 metres grading 2.1 g/t Au. This near-surface interval may in part reflect supergene enrichment and is not necessarily representative of primary mineralization at depth. Deeper in the hole, the porphyry returned three narrow intervals grading approximately 0.2 g/t Au.

These narrow, lower-grade porphyry intervals are interpreted to indicate that the apparent corridor narrows to the northwest at this position. This interpretation is preliminary and requires further drilling.

CEDDH-015 Tested the Southeastern Extension of the Corridor

CEDDH-015 was drilled to test the southeastern extension of the Ceibal corridor, approximately 210 metres southeast of CEDDH-003 (Figures 1 and 4). The hole intersected 14 metres grading 0.2 g/t Au from 74 metres downhole, the only composite returned. CEDDH-015 was collared in and drilled through basalt over approximately 90% of its length and did not intersect any porphyritic intrusive rock.

CEDDH-015 did not extend the mineralized corridor to the southeast at the position tested. The hole did not reach the modelled porphyry contact, interpreted to lie approximately 200 metres further southwest, and therefore did not test the porphyry at this position. A hole collared farther southwest, or drilled to greater depth, would be required to do so. This interpretation is preliminary and requires further drilling.

Next Drilling Designed to Resolve Corridor Orientation and Dip

Most of the drilling completed to date at Ceibal has been oriented at approximately N230°, and the Company has designed additional holes on different orientations to constrain the geometry of the system. The offset scissor pair described above (CEDDH-020 and CEDDH-021) were drilled across the corridor at approximately N100° and N280°, respectively, to help determine the dip direction of the mineralized trend and to add control on its strike. A further hole is planned toward the south to test a gap in drilling in the southwestern part of the corridor, and an additional hole is being considered toward the north to test a gap in drilling to the north-northeast of the recent step-out holes CEDDH-013, CEDDH-014, and CEDDH-016. Results from this drilling are intended to assist with the interpretation and detailed modelling.

One drill rig is currently active at Ceibal, and two rigs are completing the infill, extension, and gap drilling program at the Tesorito deposit. A fourth drill rig is on order, with the timing of its arrival uncertain. Assays are pending from both Ceibal and Tesorito.

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 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 and Lima 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, no unreported significant core recovery or drilling issues were encountered during the program. Drill core was orientated, and downhole orientation surveys were collected at regular intervals.
