Slam Drills 74.80 meter Copper, Nickel Cobalt Core Interval at Goodwin

A Breakout Critical Element Core Intercept In The Bathurst Mmining Camp

MIRAMICHI, NB / ACCESS Newswire / December 11, 2025 / SLAM Exploration Ltd. (TSXV:SXL,OTC:SLMXF) ("SLAM" or the "Company")is pleased to announce it has drilled a 74.80 meter ("m") core interval grading 0.96% copper equivalent (Cu Eq) in hole GW25-19 on the Farquharson zone at the wholly owned Goodwin Copper-Nickel-Cobalt Project. The Goodwin project covers 11,860 hectares (29,300 acres) of prospective mineral land located 35 kilometers southwest of the Caribou Mine in the mineral-rich Bathurst Mining Camp of New Brunswick.

Diamond Drilling Highlights:

Based on the core length of 74.8 meters, the true width is estimated at 50 meters at a recovered grade of 0.96% copper equivalent. The known strike length of 360 meters and depth of 200 meters point to significant tonnage potential for the Farquharson zone. The copper equivalent (Cu Eq%) values are "recovered" grades calculated using a recovery rate of 90% and based upon copper, nickel, cobalt, silver and gold prices published December 09, 2025 on the website Daily Metal Price.

The Company drilled 10 holes of NQ size core for a total of 2,603 meters in the 2025 Goodwin drilling campaign including one hole on the Granges Zone and nine holes on the Farquharson Zone. Drilling extended the strike length of the Farquharson Zone to 360 meters and the Zone is open in both directions. (see Figure 2).

Figure 2 is derived from SLAM's historic airborne MegaTEM survey that covered the entire Bathurst Mining Camp. This survey suggests potential for Farquharson zone extensions over a 7,000 meter strike length. With momentum building, the Company has initiated the next phase by requesting quotes from geophysics contractors for airborne and down-hole EM surveys. These surveys are intended to support target generation and drill planning for the promising 2026 diamond drilling campaign. The location details for hole GW25-19 are as follows:

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 completed 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. Clarence Stream is host to a 12.4M tonne indicated resource of 922,000 ounces at a grade of 2.31 g/t gold plus an inferred resource of 16.1m tonnes with 1,334,000 ounces 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 2026. 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.
