SLAM REPORTS GOLD ASSAYS FROM 7.42 TO 94.80 G/T GOLD AND ANNOUNCES RESIGNATION OF DIRECTOR/CFO

Slam Exploration Ltd. has released additional gold assay results from its wholly owned Jake Lee mineral claims, located in southwestern New Brunswick. The results were obtained from grab samples collected during the 2025 trenching program.

Eight grab samples were collected from a mineralized quartz vein exposed in bedrock within the first trench of the season (trench JT25-01). These samples returned assay values from 7.42 grams per tonne (g/t) to 94.80 g/t gold. The attached table summarizes the assay results for all eight samples.

Eight grab samples were collected from the newly identified gold vein previously reported by Slam on May 20, 2025. These samples were taken from a bedrock vein in trench JT25-01 and returned assay values ranging from 7.42 g/t to 94.80 g/t gold. The new gold discovery occurs on the flank of a 2,800-metre-long aeromagnetic anomaly.

According to the NBDNRE website, the New River gold occurrence 587 is a placer gold occurrence that dates back to the 1960s. In 1998, a bedrock discovery by prospectors produced grab samples grading up to 5.35 g/t gold. Slam's Discovery gold vein is located 2,000 metres east of the New River gold occurrence.

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

QA/QC (quality assurance/quality control) procedures: The eight reported grab samples were collected from exposed bedrock in trench JT25-01 and delivered directly to Actlabs in Fredericton, N.B., for analysis. All samples were processed using procedure 1A2 (fire assay with atomic absorption finish). Samples exceeding detection limited were reanalyzed using procedure 1A3 (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 (NBDNRE) website. Slam's exploration data referenced herein has also been disclosed in prior news releases available on SEDAR+ and at the company's website.

Corporate update -- resignation of director/CFO

The company announces that Eugene Beukman has resigned as a director and as chief financial officer, effective June 30, 2025. The board of directors extends its sincere gratitude to Mr. Beukman for his many years of dedicated service to Slam. Mike Taylor, president and chief executive officer, stated, "I personally want to thank Eugene for his long-standing commitment to the company and wish him continued success in all his future endeavours." A search process is under way to identify a successor CFO, and further updates will be provided as appropriate.

Exploration update -- Goodwin IP survey

The company is conducting an induced polarization (IP) geophysical survey over the Granges, Farquharson and Logan zones located on Slam's wholly owned Goodwin copper-nickel-cobalt claims in the Bathurst mining camp (BMC) of New Brunswick.

This program follows encouraging results from the 2024 diamond drilling campaign, in which 15 drill holes intercepted significant copper, nickel and cobalt mineralization. Highlights include:

• Granges zone: drill hole GW2402 returned a core interval of 64.90 metres grading 1.49 per cent copper equivalent (CuEq);
• Farquharson zone: drill hole GW2403 intersected 60.60 metres grading 0.84 per cent CuEq.

These CuEq values incorporate an 85-per-cent recovery rate, as disclosed in the company news release date June 30, 2025.

Slam drilled two holes and cut multiple gold-bearing veins were 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 m in news releases on Dec. 13, 2021, and Nov. 22, 2022.

The company is a project generator and expects to receive significant cash and share payments in 2025. Slam received $9,000 cash and 1.2 million shares from Nine Mile Metals Inc.
