SLAM intercepts 1.19% copper equivalent over 24.6 m in GW26-29 at Goodwin

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

MIRAMICHI, NB / ACCESS Newswire / August 14, 2026 / SLAM Exploration Ltd. (TSXV:SXL)(OTCQB:SXLXF ) (" SLAM " or the " Company ") is pleased to report a 24.60 meter ("m") core interval grading 1.19% copper equivalent ("Cu-Eq") 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.
