Infill drilling, including hole 26-SPX-RC084 (5.37 g/t Au over 8.4 m) and 26-SPX-RC100 (1.50 g/t Au over 42.4 m), is targeting resource upgrade and conversion within the pit limits

Infill assays are materially higher grade than the M&I and Inferred resource grade of 1.18 g/t and 1.72 g/t, respectively

Talamore Mining Corporation (TSX-V: TALA) (OTCQB: TALMF) is pleased to report results from 55 holes of an ongoing 40,000-metre infill and exploration drilling program at its wholly-owned Coffee Gold project in Canada’s Yukon Territory. Drilling is currently targeting the higher-grade Supremo Extension zone (Figures 1 & 2), which currently hosts an Indicated Resource of 2,437 kt at a grade of 1.18 grams per tonne (g/t) gold for a contained 92,000 ounces of gold, and an Inferred Resource of 6,059 kt at a grade of 1.72 g/t gold for a contained 335,000 ounces of gold. The Inferred grade at Supremo Extension is significantly higher than the 1.15 g/t Au grade of the overall Coffee Gold project resource estimate and thus provides a compelling target for converting high-grade ounces to the Indicated category for inclusion in the Feasibility Study currently underway.

Today’s release includes assay results from 55 reverse circulation holes totalling 7,447 metres of a planned 25,000 metres of infill drilling at Supremo Extension. A total of 157 drill holes for approximately 22,348 metres have been completed through June of this year.

Drilling Highlights

Highlights of the holes reported here from the Supremo Extension structural system include:

• 5.37 g/t Au over 8.4 m estimated true width (ETW) in hole 26-SPX-RC084
• 6.60 g/t Au over 6.6 m (ETW) in hole 26-SPX-RC033
• 5.77 g/t Au over 6.1 m ETW in hole 26-SPX-RC022
• 4.14 g/t Au over 8.8 m ETW in hole 26-SPX-RC112
• 1.50 g/t Au over 42.4 m ETW in hole 26-SPX-RC100
• 2.29 g/t Au over 14.2 m ETW in hole 26-SPX-RC068

Tim Warman, President and CEO of Talamore Mining, said “The Supremo Extension area continues to deliver drill intercepts with grades significantly higher than the resource grades in our September 2025 preliminary resource estimate (see press release dated September 15, 2025).” Mr. Warman continued “Our 2026 drilling program is designed to grow the resource base across the broader Coffee property, while maintaining a strong focus on the Supremo Extension target. Approximately 20,000 m of new infill drilling was completed at Supremo Extension ahead of the cutoff date for inclusion in the resource update for the ongoing Feasibility Study. With the infill drilling largely complete at Supremo Extension, the drills will now be moving onto other infill projects within the existing resource footprint and will also be chasing deeper oxide mineralization beneath the main Supremo resource pit, before moving on to regional targets in August.”

Geology and Context of Results

The Coffee Gold project consists of multiple mineralized structural zones forming the equivalent of a large vein swarm with individual structural zones from one to over thirty metres in width and extending up to four-kilometres in strike length (Figure 1). The Supremo Extension portion of the Coffee deposit is at the intersection of a steep dipping northeasterly trending high grade structure and a shallow dipping easterly trending structural zone. The shallow dipping structure is unique relative to the other structural zones in the Coffee deposit because of the much thicker mineralization, lower trace metals and increase in silver. The intersection of these two structural trends creates wide zones of much higher-than-average grade that become ideal for open pit mining.

• Holes 26-SPX-RC022 and 26-SPX-RC033 (Figures 2 & 3) encountered better than expected grades near the bottom of the current resource pit. These new holes also added mineralization within the current resource pit, and outside it, with mineralization remaining open at depth. These holes are drilled on a cross section between existing completed cross sections. The mineralization cut in this cross section indicates the potential for expanding the pit especially the flat bottom area of the pit. These results will also increase the grade at depth and should lower the stripping ratio.
• Hole 26-SPX-RC068 (Figure 2 & 4) extended good grade and width to within 25 metres of the surface, with grade increasing with depth. This drill hole adds confidence in good grade near the surface and continuity of similar or better grade at depth. This hole also adds mineralization within the current resource pit. The holes drilled on this cross section are between existing completed cross sections. Assays are pending on two drill holes in this cross section which would define whether the pit can be expanded at depth to include a historical high-grade intercept below the current pit.
• Hole 26-SPX-RC084 (Figures 2 & 5) helps to confirm the current resource model interpretation and shows grade and width increasing with depth. This hole intercepted mineralization within the current resource pit and adds confidence to the continuity of good grade. The holes drilled on this cross section are between existing completed cross sections. Only one new hole was needed to complete this cross section. This hole will upgrade the blocks in the steeper structure which could provide the justification for expanding the pit at depth to include part of a wider good grade intercept extending below the current pit.
• Hole 26-SPX-RC100 (Figures 2 & 6) helps to confirm the current resource model and shows increasing width and grade at depth. This hole also adds mineralization within the current resource pit and the zone remains open at depth. These holes are drilled on a cross section between existing completed cross sections. These drill results in the low angle structure are exceptionally wide and good grade which will increase the block grades and reduce the stripping ratio. The drilling also confirms high grade at the base of the pit which should upgrade the blocks in this area. There are pending assays on three other drill holes on this cross section.
• Hole 26-SPX-RC112 (Figures 2, 7) shows increased grade and confirms the model. These holes are drilled on a cross section between existing completed cross sections. This drilling upgrades blocks in the shallow dipping structure on this cross section and also adds continuity to the steeply dipping structure. One drill hole on this cross section has pending assays to give more support to the steeper dipping structure.

These 55 drill holes continue the campaign to infill between existing completed cross sections on the Supremo Extension target, to increase drill density and upgrade resources from Inferred to Indicated for inclusion in the Feasibility Study currently underway. Infill and/or expansion drilling has also started on the Supremo and Latte zones. Once the infill drilling is completed the drills will move to several of the regional targets that will be tested this summer.

The goal of targeting the higher-grade infill portion within the main Supremo Extension is to increase both the size and the grade of the resource for inclusion in the current Feasibility Study work. The current open-pit mineral resource estimate comprises:

Table 3. 2025 Coffee Gold Project Mineral Resource Estimate

Notes to Table 3:

1. Economic parameters used in the resource are a gold price of US$2,500/oz; heap leach average recoveries for the individual metallurgical domains of 86.3% for Oxide, 76.0% for Upper Transition, 54.5% for Middle Transition and 31.4% for Lower Transition; a mining cost of C$3.27-$3.50/t, processing costs of C$6.64/t, and general and administrative costs of C$6.0/t. A CAD:USD exchange rate of 1.35 was also assumed.
2. The calculated cut-off grades vary between 0.13 g/t Au and 0.48 g/t Au, depending on the metallurgical domain. The global weighted average cut-off grade is 0.18 g/t Au, with domain tonnage contributions comprising 64% Oxide, 18% Upper Transition, 5% Middle Transition, and 13% Lower Transition.
3. Pit slope angles vary between 45.0 and 48.8 degrees depending on the pit area.
4. Pit optimization was done on 12x12x10 m re-block model with a minimum of 4x4x5 m regularized SMU.
5. Numbers have been rounded to the nearest for thousand tonnes and ounces. Differences may occur in totals due to rounding.
6. The mineral resources described above have been prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum Standards and Practices.
7. Messrs. Alan J. San Martin, P.Eng. and Charley Murahwi, P.Geo. from Micon International Limited are the Qualified Person (QP) for this Mineral Resource Estimate.
8. Mineral resources are not mineral reserves as they have not demonstrated economic viability. The quantity and grade of reported Indicated and Inferred mineral resources in this news release are uncertain in nature and there has been insufficient exploration to define any measured resource; however, it is reasonably expected that a significant portion of Inferred Mineral Resources could be upgraded into Indicated Mineral Resources with further exploration.
9. Micon’s QPs have not identified any legal, political, environmental, or other factors that could materially affect the potential development of the mineral resource estimate.

Quality Assurance and Quality Control Procedures

RC samples are collected at the drill rig by a qualified subcontractor in conjunction with rock chips for logging. Samples are collected every 5 ft (~1.52 m) for the entire hole, with the exception of the first sample of each hole where intervals may be longer depending on recovery while casing is set. Large retention bags (36″x24″) are marked with the depth of the interval and small sample bags (12″x 20″) are marked with a sample ID corresponding to a sample tag book where depth interval and hole information are recorded. The sample is collected in a clean bucket from under the cyclone. The full sample and bucket are weighed and then the sample is split using a riffle splitter (1/8 split) into a retention bag and a sample bag. The retention and sample bags are weighed on a scale, and the total weight, retention bag weight, and sample bag weight are recorded in the corresponding sample tag book.

A representative spear sample is taken from the waste bucket and is dry and wet sieved on site. Chips from the sieved sample are placed in a chip tray marked with the corresponding depth interval. Retention bags are folded over and are stacked neatly at the drill site; sample bags are closed and arranged into sample shipments at the drill site. A geologist regularly checks in on each drill to ensure sample integrity, quality, and that the site is being maintained in a clean and orderly manner to prevent sampling errors and contamination. When groundwater is encountered, the drillers will attempt to “dry” the interval before it reaches the cyclone. If a sample is wet, the sample will be spear sampled rather than split, and ‘wet sample’ is noted in the tag book. A geologist will supervise sampling during wet drilling conditions to ensure the sample is representative.

The cyclone is checked regularly for contamination and cleaned as necessary, regardless of drilling conditions. The collected samples are brought to the main core processing area at the end of every shift where they are laid out and the sample count and sequence numbers are checked to verify against the completed tag books. Standards and blanks occur every 10 samples and the standard type is generated randomly in the acQuire database upon entry. Standards and blanks are inserted by the geo-technicians during shipment preparation. Standards and blanks procedures for RC sampling are the same as diamond drill core sampling.

All reverse circulation samples collected in 2026 were submitted to ALS Canada Ltd. for preparation and assaying. Samples were typically received, crushed, and pulverized by the ALS Whitehorse preparation facility, and shipped to ALS North Vancouver for assaying. Prepared samples were assayed for gold using a conventional lead-fire assay procedure (Au-ICP21, ICP-AES) on 30 g sub-samples (50 g samples were used in 2010). Fire-assayed samples with grades in excess of 10 g/t gold were re-assayed from a second 30 g split (50 g split in 2010) using a fire assay procedure and a gravimetric finish (Au-GRA21). All regular drill samples were analyzed for a suite of 48 elements utilizing a four-acid digestion with a combination of ICP-AES and ICP-MS finishes (ME-MS61).
