Announcement PDF RNS Number : 5341G Fulcrum Metals PLC 02 June 2026 THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION FOR THE PURPOSES OF ARTICLE 7 OF EU REGULATION 596/2014 (WHICH FORMS PART OF DOMESTIC UK LAW PURSUANT TO THE EUROPEAN UNION (WITHDRAWAL) ACT 2018) ("UK MAR"). Fulcrum Metals plc / EPIC: FMET / Market: AIM / Sector: Mining 2 June 2026 Fulcrum Metals plc ("Fulcrum" or the "Company" or the "Group") Soil sampling results of up to 1.46g/t gold advance high-grade drill-ready Big Bear Project, Ontario Fulcrum Metals plc (AIM:FMET), a company pioneering the use of innovative cyanide free technology to recover precious and critical metals from mine waste with additional interests in highly prospective exploration projects, is pleased to announce soil sampling results of up to 1.46g/t gold at its Big Bear Exploration Project ("Big Bear" or the "Project") in Ontario, Canada. The results define a large-scale gold target within a wider gold corridor and further advance multiple permitted, drill-ready targets ahead of future exploration activities. Highlights · Regional stand-out ~2km × 2km gold target defined within 3km gold corridor · 1460 ppb (1.46g/t) Au peak soil results; 51 highly anomalous samples over 30ppb Au · 3km gold corridor with rock samples of up to 139g/t Au · Strong correlation between high-grade soil and rock samples enhances drill targeting and extends bedrock targets · Gold target and corridor remains open for expansion · 30 drill pads permitted; multiple priority targets ready for drilling Ryan Mee, Chief Executive Officer of Fulcrum, commented: "The soil sampling programme has defined a regional stand-out gold target within a 3km corridor that remains open along strike. Results are supported by a growing dataset of high-grade soil samples grading up to 1.82 g/t Au and rock samples up to 139 g/t Au, highlighting the scale and prospectivity of the system. Soil sampling continues to be an effective tool for targeting mineralisation in areas of limited bedrock exposure, enhancing drill targeting and supporting expansion of the known gold footprint. With permits in place for up to 30 drill pads, Big Bear is a high-grade, drill-ready gold project with multiple priority targets. Our focus is now on evaluating partnership opportunities for Big Bear, consistent with our strategy at the Tully Gold Project and across our uranium portfolio." Soil sampling programme background A soil sampling programme was completed in the latter stages of 2025 which collected 639 samples over the Schreiber-Pyramid, Twomey and Schreiber Johnston Gap areas. This covers a 2km section central and to the east of an established high grade 3km corridor, infilling areas with no bedrock exposure (Figure 2). The results confirmed a stand-out regional gold target area covering approximately 2km x 2km which is open to the north, east and west including: · A new target area north of the Powerline occurrence, with 16 samples >30ppb Au, including four samples >100ppb. The east-west strike of the anomalous samples extends approximately 900m and remains open to the north. · A new target area to the southeast of Schreiber-Pyramid, with 15 samples > 30ppb Au, including four samples >100ppb, over an area measuring approximately 425m x 300m, and remaining open to the east. · Extension of the Johnston-McKenna occurrence footprint, generating an approximately 1 km-long trend of elevated soil and rock gold values, together with additional elevated gold data north and east of the Powerline occurrence.

Drill target pipeline (Figure 3) · Four drill ready prospects have been identified with significant gold assays at Schreiber-Pyramid No.1 North and No.1 South, Johnston McKenna and Cook Lake · A further five prospects for further development to drill target status at Johnston McKenna Mill, Johnston McKenna South, Schreiber-Pyramid South, Twomey Powerline, Schreiber Johnston Gap and the western extension area · The Project is open for further drill target generation along strike and to the north Additional exploration target pipeline outside the Schreiber-Pyramid area (Figure 4) The geophysical survey completed earlier this year identified multiple priority targets for investigation in addition to the more advanced Schreiber-Pyramid area: o Syenite: Two areas of strong conductance with magnetic highs and strong VTEM targets. o North: Conductive zone with magnetic highs and strong VTEM targets. o Schreiber West: A 2.2km northwestern trending anomaly associated with iron formation with coincident magnetic highs and strong VTEM targets. o Rongie: An 855 metre long, strong, late channel EM anomaly. o West Hays: A 550 metre long mid-channel conductor, where mapping shows the presence of felsic volcanics with nearby iron formation.

The Company's current projects are the tailing sites of the former Teck-Hughes and Sylvanite gold mines, located in the Kirkland Lake region of Ontario. In addition, the Company has interests in a portfolio of highly prospective mineral exploration and development projects in both Ontario and Saskatchewan Canada. Fulcrum has an agreement for exclusivity rights in respect of any licensed use of Extrakt's proven cyanide free technology on legacy gold mine waste sites over the mining districts of Timmins and Kirkland Lake. These are two of Canada's biggest gold camps with a historical production above 110Moz over the past 100 years, leaving more than 70 documented legacy mine waste sites. Fulcrum is now focused on the development of its Teck-Hughes and Sylvanite projects towards production using Extrakt's technology and positioned to scale the concept across two of Canada's historically most productive gold regions. Fulcrum believes this represents a substantial, long-term opportunity to unlock significant and largely untapped value from legacy mine waste.
