Technical disclosure & forward-looking information

Qualified Person

The scientific and technical information contained on this website has been reviewed and approved by Darren Lefort, Vice President, Exploration of Greyridge Exploration Corp. and a “Qualified Person” as defined under National Instrument 43-101 — Standards of Disclosure for Mineral Projects.

Sampling, analytical methods and data verification

Rock chip, channel and trench sample results referred to on this website are selective in nature and are not necessarily representative of the mineralisation hosted on the licences. Selective sampling is a normal and appropriate technique at the reconnaissance and target-generation stage of exploration, but is deliberately biased toward visible mineralisation and should be read accordingly.

Individual sample assays do not constitute mineral resources or mineral reserves as defined under NI 43-101 and the CIM Definition Standards, and should not be interpreted as indicative of grades or tonnages that may be defined by future drilling. No mineral resource or mineral reserve has been estimated on any Greyridge licence.

Sample results described as “pending” have been submitted for analysis and were not available at the time the relevant Company communication was released. Where assays remain outstanding this is stated on the relevant page.

Surface samples

Surface rock-chip, channel and trench samples are analysed by ALS Arabia, an independent commercial laboratory. Samples are crushed to 70% passing 2 mm and pulverised to 85% passing 75 µm. Gold is determined by 50 g fire assay with atomic absorption finish (Au-AA24) and other elements by aqua regia digestion with ICP-AES (ME-ICP41), with over-limit samples re-assayed by ore-grade methods (OG46). ALS inserts its own certified reference materials, blanks and duplicates, reported with each certificate.

Data verification. The Qualified Person has verified the results disclosed on this website against the original laboratory certificates.

Drill sampling

Reverse circulation drilling at Bahila returns one-metre samples for laboratory assay. Laboratory, sample preparation, analytical methods and quality-assurance and quality-control procedures, including the insertion of certified reference materials, blanks and duplicates, will be described with the first release of drill results.

Geological interpretations

Deposit-style classifications, alteration interpretations, hypothesised system geometries and target models presented on this website are interpretations based on surface geology, geochemistry, geophysics and remote sensing. They have not been confirmed by drilling except where expressly stated. Exploration is an inherently uncertain activity and geological interpretations frequently change when a target is drilled.

Geophysical features described on this website — including magnetic and induced polarisation anomalies and inversions — are modelled products. Depth estimates derived from geophysical modelling carry significant uncertainty and are indicative only.

Neighbouring properties and deposit analogues

References to neighbouring deposits and operations — including Ma’aden’s Al Amar mine, the Khnaiguiyah zinc-copper deposit, AMAK’s Al Masane mine, Jabal Sayid, Mansourah–Massarah, Ad Duwayhi, Bulghah, Mahd Ad Dahab and Sukhaybarat — are provided for geological context only.

Mineralisation hosted on, and grades or tonnages associated with, neighbouring properties are not necessarily indicative of mineralisation on Greyridge’s licences. Greyridge has no interest in any neighbouring property.

Third-party resource and production figures cited on this website are as reported by the relevant operator or in publicly available sources and have not been independently verified by Greyridge. Khnaiguiyah. The Khnaiguiyah resource of 73.5 million tonnes grading 2.26% Zn, 0.20% Cu and 1.65% Mn, containing approximately 1,664 kt zinc, 145 kt copper and 1,214 kt manganese, is as published by the Saudi Ministry of Industry and Mineral Resources in “KSA: Unlocking the Next Frontier of Discovery,” March 2026. The project is operated by Moxico Resources and Ajlan & Bros. The figure has not been independently verified by Greyridge, is not reported under NI 43-101, and no Qualified Person has done sufficient work to classify it as a current mineral resource. Khnaiguiyah is not a Greyridge property and Greyridge has no interest in it; the project is referenced solely as geological and jurisdictional context.

References to deposit-style analogues in other jurisdictions — principally the Andean continental margin arc, cited after Doebrich et al. (2007) in respect of the Ar Rayn terrane — are used to describe tectonic setting and deposit class only. They do not imply that mineralisation of similar style, scale or grade occurs on Greyridge’s licences.

Jurisdictional rankings are as published by the Fraser Institute in its Annual Survey of Mining Companies. Commodity price observations are general market commentary and are not forecasts.

Comparative licence expenditure commitments attributed to other operators are derived from publicly announced licence awards and tender-round results.

Forward-looking information

This website contains forward-looking information within the meaning of applicable Canadian securities legislation, including statements regarding planned exploration and drilling programs, including the scope, sequencing and completion of the Bahila drill program and the extension of reverse circulation holes with diamond tails; the timing and expected outcomes of geophysical surveys, drilling and assay results; interpreted geological and deposit models; the expected timing and amount of rebates under the Exploration Enablement Program; and anticipated portfolio advancement.

Forward-looking information is based on assumptions, including the continued availability of the drill rig and crews, laboratory turnaround times consistent with current estimates, the accuracy of the geophysical model at depth and the extent to which RC results are indicative of the geology at depth. It is subject to known and unknown risks and uncertainties — including exploration risk, the inherent uncertainty of geological interpretation prior to drilling, drilling and ground conditions, regional security conditions, equipment availability, laboratory turnaround times, commodity-price volatility, permitting, and contractor and assay-laboratory availability — that may cause actual results to differ materially from those expressed or implied.

Readers are cautioned not to place undue reliance on forward-looking information, which speaks only as of the date on which the information was first published. The Company undertakes no obligation to update forward-looking information except as required by law.

No offer of securities

Nothing on this website constitutes an offer to sell, or the solicitation of an offer to buy, any security, or investment, legal, tax or accounting advice. Readers should seek advice from their own independent advisers.

Currency of information

Technical and operational information on this website is current to October 2026 and is disclosed in accordance with NI 43-101. Exploration results, program status and prospect stages change over time; the Press Releases & Shareholder Updates carry the latest information.
