SLAM Reports New Gold Discover y – Grab Samples Assay

18.50 To 75.90 G/T Gold

New Gold Discovery By Slam On Wholly-Owned Jake Lee Claims

For Immediate Release, May 20, 2025

Miramichi, New Brunswick ‐ SLAM Exploration Ltd. (TSXV-SXL) (“SLAM” or the

“Company”) is pleased to announce a new gold discovery with four grab samples grading from

18.50 grams per tonne (“g/t”) to 75.9 g/t gold collected from a mineralized quartz vein in the first

trench of the 2025 exploration program on its wholly owned Jake Lee mineral claim in

southwestern New Brunswick. These 4 samples were submitted on a rush basis to Actlabs in

Fredericton for gold analysis as soon as the discovery vein was uncovered.

Four samples ranging from 18.50 g/t gold to 75.90 g/t gold were collected from a quartz vein in

bedrock uncovered by the first trench JT25 -01. This new gold discovery is 20 meters north of 3

quartz float samples (“JL22 float”) grading from 3.39 grams/tonne (“g/t”) to 39.30 g/t gold

previously discovered by Slam (Reference 1 below). The results for all four samples are listed in

the following table:

Sample Location Description Au G/T

L458001 JT25-01 QV. 20-30 cm wide. Laminated, iron stain. 22.50

L458002 JT25-01 Same vein with *Cp, Bn, Gn, iron oxide blebs. 18.50

L458003 JT25-01 Same vein with Cp, Bn, Gn, iron oxide blebs. 18.60

L458004 JT25-01 Same vein with Cp, Bn, Gn, iron oxide blebs. 75.90

*Abbreviations: Cp-Chalcopyrite, Bn-Bornite, Gn-Galena.

Trench JT25-02 was dug to 200 meters north of the first trench. It uncovered a 0.30 meter wide

quartz vein with minor sulphide mineralization. Trench JT25 -03 was dug to the northeast of the

first trench. Trench JT25-03 uncovered a 3 meter wide zone of quartz breccia and quartz stringers.

The stringers are locally mineralized with up to 3% sulphides including chalcopyrite, galena,

arsenopyrite and pyrite.

Sulphide mineralization occurs in both the quartz stringers and wall rock. Trench J T25-03

followed the stringer zone for 30 meters and the zone is open to the northeast. The new gold

discovery site is shown with aeromagnetics on Figure 3.

Assays are pending on 31 additional samples collected from the prospecting and trenching program

and submitted to Actlabs in Fredericton, New Brunswick for gold analysis. The Company signed

an amendment to renew its option to acquire 100% interest in the Roger Lake claim. The Jake Lee,

Love Lake and Rogers Lake claims cover 13,720 hectares of gold potential demonstrated by 12

gold occurrences associated with strong magnetic features as shown on Figure 4.

mineralization.

QA-QC Procedures: Six grab samples including 4 from the first trench and 2 from prospecting

sites were collected, tagged and delivered to Activation Laboratories Ltd. ( “Actlabs”) in

Fredericton, New Brunswick. Actlabs performed procedure 1A2 on all samples followed by the

1A3 gravimetric assay procedure for over -the-limit samples. Figures 1 and 2 are compiled from
