Bighorn Metals Corp. Advances Phase I Exploration Program for Marietta Project NewMediaWire Tue, November 10, 2026 at 2:15 AM EST 8 min read HRNY.CN 0.00% GC=F -0.60% SI=F -0.45% VANCOUVER, BC - November 10, 2026 (NEWMEDIAWIRE) - Bighorn Metals Corp. (the "Company") (CSE: HRNY) is pleased to highlight the extensive historical mine workings and reported multi-metal occurrences at its Marietta Project (the "Project"), where the Company is advancing preparations for its initial exploration program.
The Project includes patented ground covering the historic Marietta Mines and is located near a number of historical mine areas, including the Endowment, Black Hawk, Silver Gulch, Birdsong, Badger and other mined areas. Historical records relating to the Project report gold, silver and base-metal mineralization, providing a number of areas for systematic follow-up as part of the Company's proposed exploration activities.
As part of its broader geological review, the Company also intends to evaluate whether the Project warrants exploration for rare earth elements. The Company has not established a mineral resource containing rare earth elements on the Project, and further geological assessment and analytical testing would be required to determine whether exploration for rare earth elements is warranted.
Historical Mine Areas and Reported Exploration Results
Historical records describe a network of mine workings across the Marietta Project, including shafts, adits, declines, prospect pits and associated surface workings. These historical workings are expected to provide starting points for geological mapping, sampling and evaluation of geological controls on reported mineralization.
Historical records reviewed by the Company include an unpublished 2008 report prepared by McMaster that reports a sample from the Black Hawk area assaying 186.59 ounces per ton silver (Ag). The Company has not independently verified the location of the sample, the sampling methodology, analytical procedures or quality assurance/quality control procedures associated with this historical result. Accordingly, the result should not be relied upon as being representative of mineralization on the Project and is disclosed solely as historical exploration information that the Company intends to investigate through its exploration program.
Historical sampling conducted on the Project in April 2005 reportedly returned values of up to 66.1 g/t gold, 169 g/t silver and 4.3% copper. The samples were reportedly analyzed by ALS Chemex under certificate RE05029674. Other reported results from this sampling included values of up to 0.38% antimony, 0.15% bismuth and greater than 0.05% tellurium.
These results are historical in nature. The Company and its Qualified Person have not yet independently verified the sampling procedures, sample locations, analytical procedures or associated quality assurance/quality control information, and the results should therefore not be relied upon as necessarily representative of mineralization on the Project. The Company intends to further investigate the historical results through its proposed exploration activities.
Multi-Commodity Exploration Potential
In addition to reported precious-metal and base-metal occurrences, the Company intends, as part of its broader geological review, to assess available geological information to determine whether further exploration for rare earth elements on the Project is warranted.
No mineral resource containing rare earth elements has been established on the Project, and the Company has not determined that rare earth elements occur in quantities or concentrations that may have reasonable prospects for eventual economic extraction. Additional geological assessment, fieldwork and analytical testing would be required to evaluate any potential for rare earth element mineralization.
The Company's proposed Phase I exploration program is expected to focus on the compilation and assessment of historical geological and exploration records, relocating and mapping historical workings, geological reconnaissance and targeted sampling of rock exposures, mine dumps and historical workings where access and safety conditions permit.
Soil sampling and other surface exploration methods may also be undertaken to assist the Company in identifying and prioritizing areas for further exploration.
The proposed program is intended to provide modern geological and analytical information that can be used to evaluate the historical information associated with the Project and assist the Company in identifying and prioritizing potential exploration targets.
The scope, timing and completion of the proposed field activities remain subject to applicable permitting and access requirements, the availability of financing, personnel and contractors, weather and seasonal conditions, and other operating considerations. There can be no assurance that the proposed exploration activities will be completed as currently contemplated or at all.
Technical Review and Historical Information
The Company has engaged Gregory C. Ferdock, M.Sc., C.P.G., to prepare an independent technical report in accordance with National Instrument 43-101. Additional technical detail regarding the historical mine areas, source records, sampling and rare earth element potential may be incorporated following his review.
The historical exploration information described in this news release predates the Company's involvement with the Project. The Company's Qualified Person has reviewed the available historical information for the purposes of approving the scientific and technical disclosure contained in this news release but has not yet independently verified the historical sampling results described herein through a current site visit, resampling or other verification work. The Company intends to undertake additional work designed to assess historical information as its exploration activities progress.
The scientific and technical information and interpretations in this news release have been reviewed and approved by Gregory C. Ferdock, M.Sc., C.P.G., a consultant to the Company and an independent Qualified Person as defined under National Instrument 43-101 – Standards of Disclosure for Mineral Projects.
Mr. Ferdock has not yet completed a current personal inspection of the Project or independently verified the historical sampling results referred to in this news release. The historical information should therefore not be relied upon as necessarily indicative of mineralization on the Project or of results that may be obtained from the Company's future exploration activities.

The Company is an exploration-stage natural resource company engaged in the evaluation, acquisition and exploration of mineral properties, with a view to advancing prospective mineral properties through exploration and evaluation. The Company's current mineral property interests are the Marietta Project in Nevada and the Loljuh Project in British Columbia.
The Company holds an exploration lease with an option to acquire a 100% undivided interest in the Marietta Project. The Property is in the Silver Star Mining District in the Excelsior Mountains, Mineral County, Nevada. It is made up of 12 patented lode mining claims and an adjoining townsite parcel, which together cover parts of Sections 29 through 32, Township 5 North, Range 33 East, Mount Diablo Meridian.
The Company holds an option to acquire the Loljuh porphyry copper-gold project (the "Loljuh Project"). The Loljuh Project is one claim covering 1,656.73 hectares in the Omineca Mining Division of central British Columbia. It is about 40 km south of Smithers and 32 km west of Houston. The Loljuh Project is prospective for porphyry copper-gold mineralization.
Geochemical work in 2019 outlined several areas of anomalous gold and copper in soil. The surveys were widespread, with lines 400 metres apart and samples taken on 200-metre centres. Rock sampling in 2019 also returned anomalous copper and gold values from several sites within the plateau area. The aeromagnetic survey outlined several areas of alteration.
