SLAM drills 30+ m massive sulphide beneath VTEM conductor at Goodwin

SLAM Follows VTEM Survey With Massive Sulphide Intercepts in the Mineral-Rich Province of New Brunswick, Canada MIRAMICHI, NB / ACCESS Newswire / June 17, 2026 / SLAM Exploration Ltd. (TSXV:SXL ) (" SLAM " or the " Company ") is pleased to announce it has drilled over 30 meters of massive sulphide mineralization in diamond drill hole GW26-29 including a 26.10 meter ("m") massive sulfide core interval from 18.70 to 44.80 m; a 1.85 m zone from 46.75-48.60 m plus a 2.15 m zone of massive sulphides from 57.9-60.05 m. The Company has completed 4 diamond drill holes (GW26-26 to GW26-29) since mobilizing on June 1, 2026 for the 7,000 meter diamond drilling program on the Goodwin copper-nickel-cobalt project. Figure 1 Hole GW26-29 Massive Sulphide Interval All 4 holes have cut gabbro mineralized with pyrrhotite and assay results from all four holes are pending.

A fifth hole, GW26-30, is currently in progress. The first 4 holes are described as follows: GW26-26 - Designed to test a VTEM conductor 1,600 meters southeast of the Farquharson zone. Drilled at azimuth 055° and dip of -50° from a collar at 476 m elevation (N 5,237,581 / E 699,469) to a depth of 200 m.

The hole intersected a sequence of gabbro and mafic tuff with disseminated to semi-massive pyrrhotite present throughout the mineralized intervals. Pyrrhotite occurs as disseminated blebs and stringers, with massive seams from 148.15 to 148.20 and 149.27 149.60. Chalcopyrite noted in the deeper portions of the hole.

A total of 57 core samples were submitted for assay. GW26-27 - Designed to test a VTEM conductor from a collar 80 meters east of the collar for Logan Zone hole GW24-15. Drilled at azimuth 215° and dip of -60° from a collar at 393 m elevation (N 5,239,345 / E 697,310) to a depth of 110 m.

The hole intersected medium-grained gabbro with a sustained and progressive increase in pyrrhotite mineralization with depth across a 27.85 meter interval from 46.00 to 73.85 meters., demonstrating the strong association between the gabbro host rock and sulfide mineralization at this target. A total of 44 core samples were sawn and submitted for assay. GW26-28 - Designed to test a VTEM conductor from the same collar location as Logan zone drill hole GW24-08.

Drilled at azimuth 360° and dip of -45° from a collar at 395 m elevation (N 5,239,410 / E 697,180) to a depth of 163 m. The hole intersected chloritized volcanics and gabbro with disseminated pyrrhotite present throughout, including localized intervals of elevated sulfide concentration and a short interval of massive pyrrhotite from 120.42 to 120.51. A total of 9 core samples were sawn and submitted for assay.

GW26-29 - Highlight Hole - Designed to test a VTEM conductor 100 meters southeast of hole GW25-27. Drilled at azimuth 120° and dip of -80° from a collar at 395 m elevation (N 5,239,268 / E 697,385) to a final depth of 137 m, Three discrete intervals of massive sulfide were intersected within a competent gabbro host rock, with the host rock largely replaced by sulfide mineralization and core recovery remaining excellent throughout: 18.7-44.8 m: 26.1 m of massive sulfide mineralization 46.75-48.6 m: 1.85 m of massive sulfide mineralization 57.9-60.05 m: 2.15 m of massive sulfide mineralization The three zones combine for approximately 30.1 metres of massive sulfide over a downhole interval of approximately 42 metres, with the upper zone alone spanning over 26 continuous metres. Sulfide mineralization continues below the massive zones as disseminated and semi-massive pyrrhotite with associated chalcopyrite.

The geometry and continuity of the sulphide system intersected in GW26-29 is consistent with the style of mineralization observed in significant magmatic copper-nickel-cobalt deposits. A total of 64 core samples were submitted for assay, and results are anticipated to be a significant catalyst for the program All 4 holes were designed to test targets based on plate models derived from the new VTEM survey that was flown over the Goodwin copper-nickel-cobalt project in January, 2026. The VTEM plate model for L1560 predicted a flat-lying conductor of moderate (120 siemens) conductance at a vertical depth of 132.8 meters.

This correlates with massive pyrrhotite seams drilled in hole GW25-26. From a total of 432 anomalies, the Company has constructed plate models for 24 conductors that range in depth from 30 meters to 320 meters. All of these models are potential extensions to the known zones of mineralization and could represent potential ovoid-type deposits with higher-grade mineralization at depth.

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. The 7,000 meter drilling program will test for potential extensions far below and beyond the 3 known zones of copper-nickel-cobalt mineralization. The Company has drilled 25 holes on the Logan, Granges and Farquharson zones.

Significant copper, nickel and cobalt intercepts include a 64.90 meter core interval, grading 2.19% Cu-Eq (copper-nickel-cobalt), including 3.84% Cu-Eq over a 31.20 meter core interval from hole GW24-02 as reported in a news release August 7, 2024 . Significant gold values were also reported with up to 3.31 grams per tonne over 0.5m in hole GW24-01. Figure 3 shows a broader and deeper target on line 1300 that is a potential extension of the Logan copper nickel cobalt zone as well as the more conductive target directly over the Granges zone.

This target is 100 m southeast of the massive sulphide intercept in hole GW26-29. Figure 4 shows an untested target on L1120 that is similar to the profile over the Granges zone. Sampling and QA/QC Procedures: A total of 174 core samples have been collected from holes GW26-26 through GW26-29 and submitted for multi-element assay, carrying sequential identifiers 2301001 through 2301192.

Eighteen quality control samples (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 core logging facility in Bathurst.

Assay results will be reported in a subsequent news release.

This portfolio is built around the Goodwin Copper Nickel Cobalt project in the Bathurst Mining Camp ("BMC") of New Brunswick.

The Company drilled 10 holes in the 2025 diamond drilling campaign on the Goodwin copper-nickel-cobalt project. These followed significant copper, nickel and cobalt intercepts from 15 diamond drill holes reported by the Company in 2024. These include a 64.90 meter core interval grading 0.73% copper, 0.64% nickel and 0.05% cobalt for 2.19% copper equivalent ("Cu-Eq"), including 1.32% copper, 1.11% nickel and 0.09% cobalt for 3.84% Cu-Eq over a 31.20 meter core interval from hole GW24-02 as reported in a news release August 7, 2024 .

Significant gold values were also reported with up to 3.31 grams per tonne over 0.5m in hole GW24-01. The Company discovered a new gold vein at Jake Lee in 2025 and recently reported up to 40.5 g/t gold and 63.30 g/t silver from channel samples cut from the vein. A 200 meter by 400 meter soil anomaly with gold grading up to 0.98 g/t gold lies adjacent to the east and north of the new gold vein.

The Jake Lee claims are located 25 kilometers southeast of the Clarence Stream gold deposit where Galway Metals Inc. Clarence Stream is host to a 12.4M tonne indicated resource of 922,000 ounces at a grade of 2.31 g/t gold plus an inferred resource of 16.1m tonnes with 1,334,000 ounces at a grade of 2.60 g/t gold. (Reference: "Updated Mineral Resource Statement, Clarence Stream Deposits, New Brunswick, Canada, by SLR Consulting (Canada) Ltd., March 31, 2022"). The Company reported an expansion of the soil coverage on the Menneval gold project on January 7, 2026. A gold soil anomaly extends approximately 3,000 meters by 2,500 meters with gold-bearing samples ranging from 0.005 grams per tonne ("g/t") to 0.683 g/t gold.

The results indicate potential extensions to a swarm of quartz veins previously discovered by SLAM. The Company previously reported core intervals include 3,955 g/t gold over 0.1m from the No. 18 vein ( December 03, 2020 ), as well as 162.5 g/t gold over 0.2 m ( December 13, 2021 ) and 56.90 g/t gold over 0.5 m ( November 22, 2022 ) from the Maisie vein.
