SLAM Reports Copper, Nickel and Cobalt Assays and Extends Farquharson Zone Strike Length to 360 Meters at Goodwin

Drilling For Critical Elements In The Mineral-Rich Province Of New Brunswick, Canada

MIRAMICHI, NB / ACCESS Newswire / December 3, 2025 / SLAM Exploration Ltd. (TSXV:SXL,OTC:SLMXF) ("SLAM" or the "Company") is pleased to announce assay results from the first three of ten holes drilled in the 2025 diamond drilling campaign on its wholly owned Goodwin claims, located 35 kilometers southwest of the Caribou Mine in the mineral-rich Bathurst Mining Camp of New Brunswick.

Highlights include:

• 2.40% copper equivalent over 4.50 meters in hole GW24-16 on the Granges Zone; and

• 0.97% copper equivalent over 48.00 meters in hole GW-17 on the Farquharson Zone.

The copper equivalent values assume mill recoveries of 90%. Selected results are tabled below:

Copper equivalent (Cu Eq%) values are "recovered grades" with assumed recoveries of 90% and calculated using copper, nickel, cobalt, silver and gold prices published November 29, 2025 on the website Daily Metal Price. The lengths are drilled core intervals. True widths have not been determined.

The Company completed 10 holes of NQ size core drilling for a total of 2,603 meters in the 2025 Goodwin drilling campaign. This included one hole on the Granges Zone and nine holes on the Farquharson Zone. The strike length of the Farquharson Zone was extended to 360 meters and is open in both directions as shown on Figure 2.

The Company has requested quotes from geophysics contractors for airborne and down-hole electromagnetic surveys, to be conducted in preparation for the 2026 drilling campaign at Goodwin.

QA-QC Procedures: Core was collected from the drill in trays and delivered to a secure logging facility in Bathurst, New Brunswick. After logging, samples were sawn using a diamond blade. Sawn half-core samples were numbered, collected in bags, tagged and delivered to Activation Laboratories Ltd. ("Actlabs") in Fredericton. Actlabs will perform multi-element analysis using assay method UT7. Samples returning over-limit results (greater than 1%) for the UT7 are re-analyzed using method 8-AR. Blanks and standards are included in each sample series.

About SLAM Exploration Ltd: SLAM Exploration Ltd. is a publicly listed resource company with a 40,000-hectare portfolio of mineral claim holdings in the mineral-rich province of New Brunswick. Diamond drilling is in progress on the Goodwin copper-nickel-cobalt project in the Bathurst Mining Camp ("BMC") 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 meter core interval, grading 2.19% Cu-Eq (copper-nickel-cobalt), including 3.84% Cu-Eq over a 31.20 meter core interval from hole GW24-02 as reported in a news release August 7, 2024. Significant gold values were also reported with up to 3.31 grams per tonne over 0.5m in hole GW24-01.

The Company launched its 2025 exploration program with two new gold discoveries on its wholly-owned Jake Lee claims. SLAM reported eight grab samples with assays ranging from 7.42 grams per tonne ("g/t") to 94.80 g/t gold in the initial discovery on July 9, 2025. A second discovery comprised quartz float grading 16.20 and 3.78 g/t gold respectively 100 meters southwest of the initial discovery as reported August 28, 2025.The Jake Lee claims are located 25 kilometers southeast of the Clarence Stream gold deposit where Galway Metals Inc. is working on an indicated resource estimated at 922,000 oz at a grade of 2.31 g/t gold plus an inferred resource of 1,334,000 oz at a grade of 2.60 g/t gold. (Reference: "Updated Mineral Resource Statement, Clarence Stream Deposits, New Brunswick, Canada, by SLR Consulting (Canada) Ltd., March 31, 2022"). 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 December 13, 2021 and November 22, 2022. The Company had previously reported a core interval grading 3,955 g/t (127oz) gold Au over 0.1m from the No. 18 vein. These veins are associated with a soil geochemical anomaly that stretches for 3,000 meters 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 2025. SLAM received 1,200,000 shares plus cash from Nine Mile Metals Inc. (NINE) on February 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 NSR royalties and expects to receive additional cash and share payments on the Wedge copper zinc project and on the Ramsay gold project.
