LEADING EDGE MATERIALS’ FILES CPR FOR BIHOR SUD POLYMETALLIC EXPLORATION

PROJECT, ROMANIA

• 2025 exploration campaign identified significant areas of mineralisation underground in Valea

Leucii, Dibarz and Avram Iancu, with wider exploration potential across the licence.

• Underground development mapping and sampling data reveal extensive mineralisation.

• Potential exists for mineralisation between Valea Leucii, Dibarz, and Avram Iancu to be

connected, giving a mineralised zone extending approximately 6 kilometres north–south and

a similar distance east–west.

Vancouver, March 1 8, 2026 – Leading Edge Materials Corp. (“Leading Edge Materials ” or the

“Company”) ( TSXV: LEM ) ( Nasdaq First North: LEMSE ) ( OTCQB: LEMIF ) (FRA: 7FL ) is pleased to

announce that the Competent Person’s Report (“CPR”) for the Bihor Sud Polymetallic Exploration Project

(“Bihor Sud”) in Romania has been filed on the System for Electronic Document Analysis and Retrieval

(“SEDAR”).

Addison Mining Services Ltd (“AMS”, “the consultant”) w as commissioned to prepare a CPR and

independent assessment of Bihor Sud.

The reporting and interpretation of exploration data undertaken as part of the study have been prepared

in accordance with The Canadian Institute of Mining (“CIM”) Definition Standards on Mineral Resources

and Reserves (“CIM Definition Standards”) and reported in accordance with the National Instrument 43-

101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).

In accordance with NI 43 -101 and CIM Definition Standards, Bihor Sud represents an early -stage

exploration project, prospective for replacement-type, stratiform/stratabound, with U–Ni–Cu-Co–Pb-Zn-

Bi–Ag–As mineralisation.

The CPR includes a data review of the main target commodities of copper, lead and nickel (and accessory

cobalt and zinc) (and cursory observations on the project ’s uranium potential) data support, rationale

and validity of target definition.

The CPR is based on desktop study and the QP’s site visit in September 2025.

Bihor Sud - 2025 Exploration Campaign

On February 2, 2026, the Company published a detailed update of last year’s exploration results:

• Mapping and sampling data reveal extensive mineralisation, notably in the form uranium oxide

associated with jasperoid silicification; polymetallic (copper (Cu), cobalt (Co), nickel (Ni), lead (Pb)

and zinc (Zn)) sulphides hosted in silica –carbonate rocks (including uranium occurrences); and

crystalline carbonate (limestone) exhibiting disseminated and stockwork -style sulphide

mineralisation. Supergene enrichment phases, such as erythrite and annabergite, fur ther

characterise the mineralogical diversity of the licence area.

• Notably, massive sulphide mineralisation is present at the Valea Leucii, Dibarz, and Avram Iancu

prospects, with a possibility that these occurrences are interconnected, forming part of a broader

mineral system. Moreover, historical prospecting rock chip d ata reported evidence of widespread

and pervasive uranium, base and precious metal mineralisation with anomalous grades of up to 28%

Ni, > 6% Co, > 3 ppm gold (Au), with one sample returning 17.75 ppm Au, and for uranium.

• The Bihor Sud licence possesses a diverse and lengthy mining history, and despite considerable

historical extraction, the potential for a profitable, modern mining operation likely remains, with

significant areas of mineralisation observed underground in V alea Leucii, Dibarz and Avram Iancu,

and potential across the wider exploration licence.

Kurt Budge CEO comments:

“Filing the CPR for Bihor Sud marks a meaningful milestone — one that quantifies the progress we've

made and sharpens our focus on unlocking the potential we believe exists in the Avram Iancu former

mining area.

With safe access to the underground galleries now confirmed, we are finalising a targeted exploration

workplan for our geology team.

Across Bihor Sud, our strategy centres on identifying thicker, continuous mineralised lodes and high-

priority feeder structures capable of hosting significant resources — a thesis well-supported by

comparable deposits in the region, including Cavnic, Suior and Rosia Montana.

The CPR completion is designed to serve a clear purpose: providing the credible foundation needed to

attract new investment directly into the project."
