SLAM UNCOVERS ANTIMONY, GOLD AND SILVER ON ITS MOOSE

LAKE TRENCHING PROGRAM

Trenching For Antimony, Gold and Silver in the Bathurst Mining Camp of New Brunswick

Miramichi, New Brunswick –September 22, 2026 – SLAM Exploration Ltd. (TSXV: SXL, OTCQB:

SXLXF) (“ SLAM” or the “ Company”) is pleased to announce antimony assays greater than the 1%

antimony detection limit in 3 samples from trenches SKT26-01 and SKT26-08 at the Skull epithermal zone.

The Company also reports up to 1.965 grams per tonne (“g/t) gold and 73.50 g/t silver collected from

trenches SKT26-03 and SKT26-04. The results indicate the presence of a gold -silver zone in addition to

the antimony zone at Skull.

The Skull is a zone of highly silicified breccia and quartz veining with stibnite (antimony) mineralization

emplaced along the regional Moose Lake fault structure. The Company has traced the breccia zone over a

strike-length of 242 meters with 8 trenches. Preliminary results from 14 grab samples collected from the

Skull zone trenches are summarized in the table below. Antimony assays are pending on 3 samples above

the detection limit of 1.00%.

After Skull, the excavator moved 3,800 meters south east to uncover the Moose Lake zone which was

tested by 3 diamond drill holes in 1988. All 3 holes intersected epithermal breccia -style mineralization

over a strike -length of 2 85 meters . The breccia zone is associated with the fault contact between

sedimentary and granitic rocks which are variably subject to clay and kaolin alteration flanking a zone of

silicified breccia and quartz veining. The Moose Lake occurrence is open in all directions.

The Moose Lake antimony project covers the Moose Lake, Stewart and Skull antimony gold showings all

discovered in 1986. The Moose Lake project was acquired through an option agreement signed March 30,

2026 as announced April 07, 2026. Contiguous to Moose Lake, SLAM’s wholly-owned Slacks Lake claim

2

group covers a number of antimony anomalies detected in regional till surveys and associated with the

Moose Brook fault zone. Together the Moose Lake and Slacks Lake claims cover 3, 895 hectares of road-

accessible mineral potential underlain by volcano -sedimentary rocks located in the mineral -rich Bathurst

Mining camp of New Brunswick, Canada. The mineral occurrences and claim boundaries for the Slacks

Lake-Moose Lake project and for the Goodwin Copper-Nickel-Cobalt project are shown on Figure 1.

Mineral occurrences and deposits are shown as yellow stars. The Skull, Moose Lake and Stewart antimony

occurrences are shown within the Moose Lake claim boundaries. All 3 antimony occurrences are spatially

associated with the Moose Lake fault. This fault also transects the southern projection of the Goodwin claim

group. The 4 known Goodwin copper-nickel-cobalt deposits are shown along with the recently announced

new Discovery 2,000 meters northwest of the Logan zone. Samples from the Skull and Moose Lake

antimony breccia zones are shown below:

Goodwin Project

The drill is currently set up on hole GW26- 42, designed to test a VTEM plate model conductor 200 meters north of

hole GW26-33 on the Granges zone and 200 meters south of hole GW26-29 on the Logan Zone. The Goodwin copper-

nickel-cobalt project covers 14,000 hectares (35,000 acres) in the mineral -rich Bathurst Mining Camp (“BMC”) of

New Brunswick, Canada. Background on the VTEM survey, target generation and the design of the current 7,000

meter program is set out in the Company's news releases dated June 1 and June 17, 2026. Significant historical

intercepts on the property include a 64.90 meter core interval grading 2.19% Cu- Eq, including 3.84% Cu- Eq over a

31.20 meter core interval, from hole GW24-02, as reported in a news release dated August 7, 2024.

Sampling and QA/QC Procedures

5

A total of 36 grab samples have been collected from t renches and prospecting sites. All samples were collected,

labelled and sealed by SLAM field personnel then shipped to a laboratory for multi -element ICP and gold analyses .

Assay results will be reported in subsequent news releases as they are received.
