SLAM IP SURVEY EXPANDS TARGET BENEATH

FARQUHARSON COPPER-NICKEL-COBALT ZONE AT

GOODWIN

High-Resolution IP Survey Shows Potential At Depth

For Release 7:30 EST, August 21, 2025

Miramichi, New Brunswick ‐ SLAM Exploration Ltd. (“SLAM” or the “Company”)

(TSXV-SXL) is pleased to announce results f or Line L3300E, the third line of an induced

polarization (“IP”) survey conducted over the Granges, Farquharson and Logan copper -nickel-

cobalt zones on its wholly owned Goodwin claims in the mineral-rich Bathurst Mining Camp of

New Brunswick. The IP survey suggests potential for extensions of all three zones at depth.

The Company has requested proposals from several drilling contractors for a 4,000 meter drilling

program on this road -accessible project. The primary objective is to expand the Granges and

Farquharson copper-nickel-cobalt zones a long strike and at depth. SLAM previously reported a

64.90-meter cor e interval grading a 1.61% copper equivalent (“CuEq”) * from 23.60 to 88.50

meters in hole GW24-02, drilled on the Granges Zone.

SLAM CEO Mike Taylor state d, “Our IP and drilling results demonstrate that the Goodwin

copper-nickel-cobalt project has the potential to contribute meaningfully to Canada’s critical

elements portfolio in the mineral-rich province of New Brunswick. Copper, nickel and cobalt are

key metals in Canada’s economic strategy for critical elements, and we expect Goodwin to play a

significant role.” The Management Committee adds “ With the outstanding IP targets identified

on the latest maps and those previously published , the Board looks forward to the drilling

campaign”.

Line L3300E crosses the Farquharson zone and passes directly over hole GW24-03, located at

1760N on this line . The Company intends to test the Farquharson Zone , where prior drilling

returned a 60.60-metre interval grading 0.90% CuEq from 72.90 to 133.50 metres in hole GW24-

03.The planned drilling program aims to identify potential higher grade mineral zones and depth

extensions of the Granges and Farquharson Zones. The Company is also planning additional IP

surveys to extend the target area.

The CuEq grades disclosed herein were calculated using an 85% recovery rate, based on assays

previously reported in Company news releases dated August 7, 2024 (hole GW24 -02) and

August 12, 2024 (GW24-03).

Chargeabilities of up to the 995 mV/V define deep targets on Line L3300E below the

Farquharson zone . These chargeability anomalies are associated with resistivity lows at depth

and to the north (north is to the right on Figure 1). Figure 1 also shows the Farquharson zone

core intercepts for diamond drill hole GW24 -03 and GW24 -04, both of which are located on

L3300E.

About Jake Lee Gold : As previously reported in the Company’s news release dated July 9,

2025, eight grab samples collected from a bedrock vein in Trench JT25 -01 returned gold assay

values ranging from 7.42 g rams per tonne (“g /t”) to 94.80 g/t. Assays are pending on additional

samples collected from the same area.

About SLAM Exploration Ltd: SLAM Exploration Ltd. is a publicly traded resource company

with a 40,000-hectare portfolio of mineral claim holdings in the mineral -rich province of New

Brunswick. The Company commenced its 2025 exploration season with a new bedrock gold

discovery on its Jake Lee Gold Project, reporting four samples grading between 18.50 g/t and

75.90 g/t gold (see news release dated May 20, 2025 ), followed by eight samples ranging from

7.42 g/t to 94.80 g/t ( see news release dated July 9, 2025).

The Company intends to resume its 2025 exploration program on the Goodwin copper-nickel-

cobalt project as soon as the fire season ends and the roads open . The Company plans additional

IP and diamond drilling to test three mineral zones where SLAM completed 15 diamond drill

holes in 2024. The 20 24 program included drill hole GW24 -02 on the Granges Zone with a

64.90-meter core interval grading 1.61% CuEq, from 23.60 meters to 88.50 meters (CuEq

calculated using an 85% recovery rate based on assay results disclosed in the Company’s news

release dated August 7, 2024).

SLAM operates as a project generator and expects to receive significant cash and share

consideration in 2025. Notably, on February 28, 2025 Slam received $9,000 in cash and

1,200,000 shares of Nine Mile Metals Inc. ( CSE:NINE) pursuant to the Wedge project

agreement. On March 29, 2025, t he Company also received a cash payment of $ 60,000 and

180,000 shares of a private company pursuant to the Ramsay gold agreement. The Company

retains net smelter return (NSR) royalties on both projects and expects additional cash and share

payments.
