Tiger Gold Corp. (TSX-V: TIGR) (FSE: D150) (OTCQB: TGRGF) is pleased to report assay results from seven infill drillholes (TSDH-89 to TSDH-95) at its Tesorito gold deposit. Tesorito is part of the Company’s 100% owned Quinchía Gold Project in Colombia’s prolific Mid-Cauca gold belt. Drilling is ongoing at Quinchía, with one rig at Tesorito, where the planned program is nearing completion, and two rigs at Ceibal.

Highlights:

• TSDH-89 intersected 333.57 m @ 0.5 g/t Au from 6 m downhole, including:
  • 8 m @ 1.4 g/t Au
  • 10 m @ 1.0 g/t Au
  • 5 m @ 1.0 g/t Au
• TSDH-95 intersected 342 m @ 0.5 g/t Au from 92 m downhole, including:
  • 9.7 m @ 1.7 g/t Au
• TSDH-94 intersected 218.91 m @ 0.5 g/t Au from 296 m downhole, including:
  • 5 m @ 1.1 g/t Au
• TSDH-92 intersected 243.4 m @ 0.5 g/t Au from 2 m downhole, including:
  • 7.2 m @ 2.8 g/t Au
  • 6 m @ 2.8 g/t Au
• Assays are pending from the ongoing Tesorito and Ceibal drill programs

Robert Vallis, President & CEO, commented, “Infill drilling continues to improve our picture of Tesorito. It has traced a north-northeast trend extending from the core of the deposit, where grades are consistently coming in above what is currently modelled. These are very encouraging results, and we expect them to contribute to the updated resource estimate we’re 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 drillhole collar and section locations. Figures 2 to 5 present cross sections through the reported section lines. Figure 6 is a regional map of the Quinchía Gold Project. All reported intervals are downhole core lengths and estimated true widths are presented in Table 1.

Infill Drilling Extends a Higher-Than-Modelled Trend Towards the Northeast

The Tesorito deposit hosts an Inferred Mineral Resource of 104 million tonnes grading 0.47 g/t Au, containing 1.57 million ounces of gold, at a 0.2 g/t Au cut-off. The results reported in this release show broad gold mineralization along a north-northeast trend through the core of the Tesorito deposit, aligned with the interpreted approximate N030°-striking structural grain.

Along this trend, drilling has returned grades above local block model. TSDH-89, TSDH-90, TSDH-92, and TSDH-95, which the model had estimated at approximately 0.4 g/t Au (below the deposit’s average grade of 0.47 g/t Au), returned grades typically more than 25% higher than the block model estimates over these intervals. Similarly, the previously reported holes TSDH-86 to TSDH-88, modelled at approximately 0.6 g/t Au, returned grades typically more than 50% higher.

These infill drilling results indicate that grades in this portion of the model are higher than currently modelled and are expected to support an improved representation of grade in the next update to Mineral Resource estimate. TSDH-91, TSDH-93, and TSDH-94, which returned grades at or below the current model, appear to refine the margins of the deposit and are not expected to adversely affect the Mineral Resource.

TSDH-89 Returns 333.57 m @ 0.5 g/t Au from Near Surface

TSDH-89 intersected 333.57 metres grading 0.5 g/t Au from 6 metres downhole, as shown in Section A-A’ (Figure 2). The interval includes 8 metres grading 1.4 g/t Au, 10 metres grading 1.0 g/t Au, and 5 metres grading 1.0 g/t Au. The hole was completed to 346.1 metres, exceeding its planned depth.

Mineralization is hosted within porphyritic andesite, multiple early diorite phases, and two intrusive breccias. Logging identified weak to moderate potassic alteration overprinted by chlorite-sericite near surface, strengthening to strong potassic alteration with secondary biotite and potassium feldspar at depth. The first intrusive breccia, from 107.6 metres to 144.1 metres, carries a high-temperature vein assemblage that includes unidirectional solidification texture (UST), A-type, B-type, and M-type veins, together with disseminated pyrite, chalcopyrite, and molybdenite. Below the early diorite, an alternating sequence of intrusive breccia and porphyritic andesite from approximately 257 metres to 340 metres is strongly altered and veined, hosting A-type, B-type, and M-type veins with persistent chalcopyrite. UST veinlets, present in the upper breccia, are absent from this interval.

TSDH-89 sits alongside TSDH-86, TSDH-87, and TSDH-88, previously reported in the Company’s news releases of June 4 and June 16, 2026. Together these holes define a coherent, broadly mineralized interval through this part of the Tesorito deposit, and include some of the longest and highest-grade intervals drilled to date by Tiger at Tesorito.

Across Section A-A’ (Figure 2) from northwest to southeast, TSDH-89, TSDH-88, TSDH-87, and TSDH-86 are interpreted to record progressively more peripheral, upper levels of the porphyry system. TSDH-89, the northwestern-most and deepest of these four holes, intersected strengthening potassic alteration at depth and intrusive breccias hosting UST and A-type veins. The Company interprets these as the most proximal, higher-temperature features intersected on the section. TSDH-88 and TSDH-87 intersected early diorite with potassic alteration overprinted by chlorite-sericite, B-type quartz-sulphide and M-type magnetite veinlets. TSDH-86, the southeastern-most and shallowest hole, intersected early diorite with weak to moderate potassic alteration and B-type veinlets, interpreted as the upper, peripheral part of the system.

These high-temperature features in TSDH-89 are comparable to those in the equigranular early diorite intersected at depth in TSDH-71 (89.96 m @ 0.9 g/t Au), whose deep, higher-grade core (16.9 m @ 2.3 g/t Au) has been interpreted as a potential feeder.¹ These high-temperature features are interpreted as indicating proximity to an intrusive centre at depth within the porphyry system.

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

TSDH-90, TSDH-91, and TSDH-92 Bracket a North-Northeast-Striking Structure

TSDH-90, TSDH-91, and TSDH-92 were drilled along Section B-B’ (Figure 3). TSDH-90 intersected 311.6 metres grading 0.4 g/t Au from 7 metres downhole, a single, long, gold-dominant porphyry interval. It is hosted in porphyritic andesite cut by early diorite and intramineral diorite, with potassic alteration (secondary biotite and potassium feldspar) beneath a chlorite-sericite overprint. A B-type quartz-potassium feldspar and M-type magnetite stockwork carries chalcopyrite and molybdenite from near bedrock to the base of the hole, which ended in the footwall sandstone-mudstone unit.

TSDH-91 and TSDH-92 were drilled approximately 80 metres apart along Section B-B’ (Figure 3) and returned markedly different results. TSDH-91 intersected 145 metres grading 0.3 g/t Au from 1 metre in potassic-altered early diorite and andesite and appears to lie beyond the eastern margin of the higher-than-modelled trend. TSDH-92, a step-back from TSDH-91, intersected 243.4 metres grading 0.5 g/t Au from 2 metres, including higher-grade shoots of 7.2 metres grading 2.8 g/t Au and 6.0 metres grading 2.8 g/t Au, and intense potassic alteration.

These two holes are interpreted as bracketing the north-northeast-striking structure, with the more strongly mineralized rock preserved on its northwestern side. The near-surface higher-grade interval in TSDH-92, from 22 to 29.2 metres, lies within supergene-altered saprolite and may in part reflect supergene enrichment, which may not necessarily be representative of primary mineralization at depth.

The high-temperature features logged around TSDH-92, including actinolite and A-type veinlets, together with the UST logged in TSDH-89, TSDH-91, TSDH-93 and TSDH-94, are interpreted as indicating proximity to an intrusive centre and the magmatic-hydrothermal transition of the porphyry system. These features are comparable to those in the equigranular early diorite intersected at depth in TSDH-71 (89.96 m grading 0.9 g/t Au), whose deep, higher-grade core (16.9 m grading 2.3 g/t Au) is interpreted as a potential feeder zone.

TSDH-95 Suggests the Higher-Than-Modelled Trend Continues to the Northeast

TSDH-95, the northernmost hole reported to date in this Tesorito drill program, was drilled along section C-C’ (Figure 4) and intersected 342 metres grading 0.5 g/t Au from 92 metres downhole, including 9.7 metres grading 1.7 g/t Au from 296 metres. A separate near-surface interval of 78 metres grading 0.2 g/t Au was returned from surface. Mineralization is hosted in porphyritic andesite intruded by early diorite, potassic-altered from approximately 115 metres, with a magnetite-bearing quartz-potassium feldspar stockwork. The highest-grade gold in the hole is associated with late base-metal shear veins rather than with the disseminated stockwork. The hole ended at 459 metres in basalt beneath the sandstone-mudstone marker unit.

The results in TSDH-95 are interpreted as indicating that the higher-than-modelled trend striking approximately N030° continues to the north-northeast. Drilled holes TSDH-99, TSDH-100, and TSDH-110 are positioned to test this potential higher-than-modelled strike trend along this same section line. TSDH-97, TSDH-98, and TSDH-102 are positioned to test this trend’s north-northeastern extension.

TSDH-93 and TSDH-94 Refine the Northwestern Margin

TSDH-93, drilled on section D-D’ (Figure 5), and TSDH-94 drilled on section A-A’ (Figure 2), both intersected a broad upper interval of argillic and phyllic alteration through porphyritic andesite, with potassic alteration and the associated quartz-potassium feldspar and magnetite stockwork developed only at depth within an early diorite package. TSDH-94 returned 218.91 metres grading 0.5 g/t Au from 296 metres, including 5 metres grading 1.1 g/t Au, within that deeper potassic package. TSDH-93 returned several composites, including 85.16 metres grading 0.4 g/t Au and 104.2 metres grading 0.3 g/t Au, beneath the Mineral Resource conceptual pit shell. Both holes continued into a thick footwall basalt beneath the porphyry-altered rock. TSDH-93 and TSDH-94 are interpreted as recording the structurally disrupted, lower-grade northwestern margin of the Tesorito system.

Drill Program and Upcoming Milestones

The current diamond drilling program at Tesorito comprises more than 11,670 metres of diamond drilling over 47 holes drilled to date and is expected to conclude near the end of this month. The Company expects to report an updated Mineral Resource estimate for the Tesorito deposit in the first quarter of 2027.

One of the two rigs at Tesorito was recently mobilized back to the nearby Ceibal project area. Upon completion of the Tesorito program, the remaining rig will also mobilize to Ceibal, for a total of three rigs to complete the drill program. The Ceibal program is intended to support a maiden Mineral Resource estimate that the Company is targeting to report near the end of the first quarter of 2027.

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. Core was sampled over nominal 2-metre and 4-metre intervals depending upon lithology, adjusted to geological boundaries. 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 quality assurance and quality control practices, certified reference materials, coarse blanks, and quarter-core duplicates are inserted into the sample stream to monitor analytical performance. Mr. García has verified the data underlying the results disclosed in this news release, including the sampling, analytical, and test data, by reviewing the certified reference material, blank, and duplicate QA/QC results against the assay database, and neither Mr. García nor Mr. Link is aware of any limitations on that verification. 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.
