SLAM UNCOVERS MINERALIZED QUARTZ VEIN AT JAKE LEE

Slam Exploration Ltd. has completed channel sampling of the No. 1 vein on its wholly owned Jake Lee project, located in southwestern New Brunswick. Assays are pending on 11 channel samples sawn from the No. 1 vein, which has produced gold grades ranging from 7.42 grams per tonne to 94.80 g/t gold since discovery as reported July 9, 2025. The Jake Lee project is located 25 kilometres southeast of the Clarence Stream gold deposit operated by Galway Metals Inc. in New Brunswick, Canada. The No. 1 vein was cleaned prior to channel sampling.

Other quartz veins were uncovered in trenches 7,500 metres southwest of the No. 1 vein, where the company had previously discovered a quartz-carbonate zone. Both the No. 1 vein and the quartz-carbonate zone occur on the north flank of a magnetic low that is thought to represent a regional fault zone.

The company uncovered angular quartz rubble with chalcopyrite-bornite mineralization in a trench and 1,600 metres southeast of the No. 1 gold vein. This trench is 200 metres north of the CT vein and represents a potential extension of that vein. Chalcopyrite-bornite mineralization is also associated with the No. 1 gold vein.

New Brunswick junior mining assistance program

The company has been awarded $45,000 from the province of New Brunswick under its junior mining assistance program in support of the 2025 Jake Lee gold exploration campaign.

Quality assurance/quality control procedures: Eleven channel samples were sawn from exposed bedrock in trench JT25-01 and delivered directly to Actlabs in Fredericton, N.B., for analysis. In addition, 52 grab samples collected from a trenching/prospecting program on the Jake Lee claim. Actlabs will analyze all the samples for gold using procedure 1A2 (fire assay with atomic absorption finish) and 1A3 (gravimetric finish) for overlimit samples. Actlabs will also use the ICP 1E3 method to analyze the samples for multiple elements.

About Slam Exploration Ltd.

Slam Exploration is a publicly listed resource company with a 40,000-hectare portfolio of mineral claim holdings in the mineral-rich province of New Brunswick. The company drilled 10 holes in the 2025 diamond drilling campaign on the Goodwin copper-nickel-cobalt project in the Bathurst mining camp of New Brunswick. The drilling program follows significant copper, nickel and cobalt intercepts from 15 diamond drill holes reported by the company in 2024 on the Goodwin project. These include a 64.90-metre core interval, grading 2.19 per cent copper equivalent (copper-nickel-cobalt), including 3.84 per cent CuEq over a 31.20-metre core interval from hole GW24-02 as reported in a news release dated Aug. 7, 2024. Significant gold values were also reported with up to 3.31 grams per tonne over 0.5 metre in hole GW24-01.

Assays are pending on 11 channel samples collected on the No. 1 gold vein as well as 52 grab samples collected along strike of the No. 1 vein on Slam's wholly owned Jake Lee claims. The company reported eight grab samples with assays ranging from 7.42 grams per tonne to 94.80 g/t gold from the No. 1 gold vein on July 9, 2025. A second discovery comprised quartz float grading 16.20 and 3.78 g/t gold, respectively, 100 metres southwest of the initial discovery as reported Aug. 28, 2025.

The Jake Lee claims are located 25 kilometres southeast of the Clarence Stream gold deposit. Clarence Stream is host to a 12.4-million-tonne indicated resource of 922,000 ounces at a grade of 2.31 g/t gold plus an inferred resource of 16.1 million tonnes with 1,334,000 ounces at a grade of 2.60 g/t gold. Slam's exploration team recently mobilized back to Jake Lee.

Slam reported gold-bearing core intervals including 162.5 g/t gold over 0.2 m and 56.90 g/t gold over 0.5 m from the Maisie vein in news releases on Dec. 13, 2021, and Nov. 22, 2022. The company had previously reported a core interval grading 3,955 g/t (127 ounces) gold Au over 0.1 m from the No. 18 vein. These veins are associated with a soil geochemical anomaly that stretches for 3,000 metres along strike. Assays are pending on 900 additional samples to expand the soil coverage and further define the target on this extensive vein system.

The company is a project generator and expects to receive significant cash and share payments in 2026. Slam received 1.2 million shares plus cash from Nine Mile Metals Inc. on Feb. 28, 2025, pursuant to the Wedge project agreement. On March 29, 2025, the company received a cash payment of $60,000, as well as 180,000 shares of a private company pursuant to the Ramsay gold agreement. The company holds net smelter return royalties, and expects to receive additional cash and share payments on the Wedge copper-zinc project and on the Ramsay gold project.
