SLAM REPORTS NEW GOLD DISCOVERY: UP TO 16.20 G/T GOLD

Slam Exploration Ltd. has made a second gold discovery on its wholly owned Jake Lee mineral claims, located in southwestern New Brunswick.

Four grab samples were collected from trench JT25-05, with assay results as follows.

This newly identified zone, referenced as JL No. 2, is situated approximately 100 metres south of the company's initial discovery, designated as JL No. 1. Slam previously reported the JL No. 1 discovery in a July 9, 2025, news release, which detailed eight grab samples with assay values ranging from 7.42 grams per tonne to 94.80 g/t gold from a mineralized quartz vein exposed in trench JT25-01.

Both gold-bearing zones are located roughly 2,000 metres east of the historic New River gold occurrence (No. 587 in the New Brunswick mineral occurrence database). While No. 587 was originally identified a placer gold occurrence in the 1960s, prospectors in 1998 discovered mineralized bedrock grab samples grading up to 5.35 g/t gold. All three occurrences, JL No. 1, JL No. 2 and New River are aligned with a series of aeromagnetic anomalies extending 2,800 metres across the Jake Lee mineral claims.

The company intends to conduct additional trenching in September to further evaluate JL No. 1 and JL No. 2 zones. These areas represent the first of 34 gold targets identified across the Jake Lee and adjacent Love Lake claim group. Targets include:

• A historical quartz float occurrence grading 302.5 g/t gold;
• Soil geochemical anomalies with one sample at 10 g/t gold, 306 samples ranging 0.01 to 1.00 g/t and 3,570 samples ranging 0.002 to 0.010 g/t gold from a total of 7,316 samples;
• Stream sediment samples from previous work returning 0.20 to 3.58 g/t gold in 22 of 60 samples.

These results underscore the widespread presence of gold within the 13,000-hectare Jake Lee-Love Lake-Rogers Lake project area.

Cautionary statement: Grab and float samples are selective by nature, and may not be representative of the overall mineralization on the property.

Quality assurance/quality control procedures: Four grab samples were collected from exposed bedrock in trench JT25-01 and delivered directly to Activation Laboratories Ltd. in Fredericton, N.B., for analysis. All samples were processed using Procedure 1A2 (fire assay with atomic absorption finish). Samples exceeding the detection limit were reanalyzed using Procedure 1A3 (fire assay with gravimetric finish).

Historical data are sourced from public disclosures, including news releases filed on SEDAR+ and reports of work published on the New Brunswick Department of Natural Resources and Energy Development website. Slam's exploration data referenced herein have also been disclosed in prior news releases available on SEDAR+ and on the company's website.

Exploration update -- Goodwin induced polarization survey

The company recently conducted induced polarization geophysical surveys over the Granges, Farquharson and Logan zones on its wholly owned Goodwin copper-nickel-cobalt claims, located within the Bathurst mining camp of New Brunswick. The surveys identified IP chargeability anomalies along three lines in the vicinity of the Granges, Farquharson and Logan sones, suggesting potential extensions of mineralization at depth.

The company has requested proposals from drilling contractors for a 4,000-metre drill program on this road-accessible project. The program is designed to expand the Granges and Farquharson copper-nickel-cobalt zones along strike and at depth.

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. As reported above, the company has made two new gold discoveries on its Jake Lee project, and plans to resume its successful prospecting-trenching program on the Jake Lee, Love lake and Rogers Lake claims in the fall.

Slam drilled two holes and cut multiple gold-bearing veins on its wholly owned Menneval gold project in 2024. The company previously reported gold-bearing core intervals including 162.5 g/t gold over 0.2 m and 56.90 g/t gold over 0.5 metre in news releases on Dec. 13, 2021, and Nov. 22, 2022. The company is currently expanding the soil coverage with 1,000 additional samples to expand 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 $9,000 in cash and 1.2 million shares 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.
