New Sulphide Discoveries Drilled On VTEM Targets Up To 2,000 Meters Along Strike From the Logan And Granges Zones In The Bathurst Mining Camp of New Brunswick

SLAM Exploration Ltd. (TSX-V: SXL, OTCQB: SXLXF) is pleased to report a 24.60 meter core interval grading 1.19% copper equivalent from the massive sulphide zone previously reported in hole GW26-29 (see news release dated June 17, 2026). In addition, the Company has made several new discoveries by testing VTEM plate models. These include a new discovery of massive sulphides in hole GW26-36 located 2,000 meters northwest of the Logan zone. This is a major extension of the copper-nickel cobalt potential at Goodwin. The Company has drilled 2,600 meters in 12 holes (GW26-26 through GW26-38), roughly 37% of the 2026 drilling program, and has submitted 992 core samples for multi-element assay.

Diamond Drilling Highlights – Hole GW26-29:

As previously reported, hole GW26-29 is a 100 meter step-out along strike to the southeast of hole GW25-15 on the Logan zone. Cu Eq% values are recovered grades calculated using a 95% recovery rate and metal prices for copper, nickel and cobalt published August 11, 2026 on Daily Metal Price. A total of 64 core samples were submitted for assay from GW26-29.

Drilling Update: 12 Holes Drilled

The Company has drilled 12 holes, GW26-26 through GW26-38, all designed to test VTEM plate model targets along the Logan, Granges and Farquharson trend. Testing of these VTEM targets has been very successful and has resulted in several new discoveries. All 12 holes have intersected the host gabbro with variable sulphide mineralization ranging from disseminated to massive. Samples from all 12 holes have been submitted for assay.

GW26-32 (317 m)

GW26-32 intersected a gabbro host with multiple stacked mineralized zones between 84 m and 308.7 m and several massive to semi-massive sulphide intercepts at depth including a massive sulphide interval from 287.1–287.9 m. A total of 271 samples, including QA/QC standards and blanks, were submitted for assay.

GW26-33 (233 m)

GW26-33 intersected a 14.5 meter zone of semi-massive pyrrhotite-chalcopyrite mineralization from 33.15 to 47.6 m, including massive sulphide from 33.15–35 m and a semi-massive interval from 42.6–47.1 m, hosted in gabbro. Background mineralization of 1–2% pyrrhotite continues through the remainder of the hole to 197.7 m.

GW26-36 (212 m)

GW26-36 intersected a broad mineralized zone from 124.4 to 191.8 m hosted in coarse-grained gabbro, containing several massive sulphide intervals – including 126.5–128.6 m, 140.7–142.0 m, 142.35–142.4 m, 144.5–144.7 m and 151–151.7 m together with semi-massive zones at 157–158 m and 165.4–166.3 m. A shallower semi-massive interval was also logged from 12.40–12.75 m. This new sulphide discovery is located 2,000 meters northwest of the Logan zone.

NBJMAP Grant Of $60,000

SLAM Exploration Ltd. has been awarded a grant of $60,000 by the Province Of New Brunswick in support of the 2026 diamond drilling campaign on the Goodwin copper-nickel-cobalt project. The Company wishes to thank the Province for its continued support and recognition of the strategic mineral potential at Goodwin.

Sampling and QA/QC Procedures

A total of 992 core samples have been collected from the 12 completed holes (GW26-26 through GW26-38, excluding the abandoned GW26-35) and submitted for multi-element assay. Quality control samples, comprising certified reference standards and blanks, were inserted at regular intervals in accordance with industry-standard protocols. All samples were collected, labelled and sealed by SLAM field personnel. Core is stored securely at the Company’s core logging facility in Bathurst. Assay results will be reported in subsequent news releases as they are received.

About the Goodwin Project

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.

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. The portfolio is built around the Goodwin Copper Nickel Cobalt project in the Bathurst Mining Camp (“BMC”) of New Brunswick. The Company also holds the Jake Lee gold project, where a new gold vein discovered in 2025 has returned up to 40.5 g/t gold and 63.30 g/t silver from channel samples, and the Menneval gold project, where a soil anomaly measuring approximately 3,000 by 2,500 meters has returned gold-bearing samples up to 0.683 g/t gold.

SLAM is a project generator and expects to receive further cash and share payments in 2026. In 2025, the Company received 1,200,000 shares plus cash from Nine Mile Metals Inc. (NINE) pursuant to the Wedge project agreement, and a cash payment of $60,000 plus 180,000 shares of a private company pursuant to the Ramsay gold agreement. The Company holds NSR royalties and expects additional cash and share payments on both the Wedge copper-zinc project and the Ramsay gold project.
