Bahia Metals advances mineral resource estimate for nickel-copper-cobalt project

VANCOUVER, British Columbia, July 29, 2026 (GLOBE NEWSWIRE) -- Bahia Metals Corp . ( CSE: BMT ) (“Bahia” or the “Company”) is pleased to announce that it is advancing preparation of an initial mineral resource estimate (“ MRE ”) for the Company’s flagship asset Mangueiros Main, a sulphide nickel-copper-cobalt-platinum group metals (“ PGM ”) project (“ Mangueiros Main ” or the “ Project ”) in Bahia State, Brazil. The MRE is being prepared by P&E Mining Consultants Inc. (“ P&E ”), an independent geological and mine engineering firm, and will be contained in a technical report prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“ NI 43-101 ”).

The MRE is the next technical milestone in the Company’s strategy to evaluate and advance Mangueiros Main from an exploration target to a development opportunity.

Independent Mineral Resource Estimate Underway P&E is completing a review of the historical drilling, geological interpretation and modelling, assay database and other supporting technical information in preparing the initial MRE for Mangueiros Main.

The Company benefits from an extensive technical database and historical exploration program that has confirmed nickel-copper-cobalt sulphide mineralization associated with an ultramafic intrusive system at Mangueiros Main, providing a strong foundation for ongoing resource evaluation and project advancement.

Once completed, the MRE is expected to provide a basis for the Company to evaluate potential future technical and economic studies.

Stephen Goodman, CEO and Director of Bahia Metals commented: “Our focus is to advance the development opportunity that Mangueiros Main presents. Completing an independent initial mineral resource estimate is an important step in building a technical foundation for advancing the potential of Mangueiros Main as a development opportunity.

If the targets outlined in the SRK Technical Report can be confirmed with an MRE, the potential for a low strip sulphide nickel copper cobalt development opportunity will provide a further basis for advancing independent technical studies.”

The Company’s current independent technical report, prepared by SRK Consulting (U.S.), Inc. (“SRK”), identifies an exploration target at Mangueiros Main ranging from 75 million to 200 million tonnes grading between 0.20% and 0.25% nickel in sulphide (“NiS”)1. The SRK exploration target provides an initial technical benchmark and starting point for P&E’s independent review and MRE work.

1 The potential quantity and grade of the exploration target are conceptual in nature. There has been insufficient exploration to define a mineral resource, and it is uncertain whether further exploration and technical work will result in the exploration target being delineated as a mineral resource. The exploration target is not a CIM-defined mineral resource or mineral reserve and should not be treated as such. P&E will independently review the available data, geological interpretation, estimation parameters and other relevant technical information, and the size, grade and classification of any mineral resource ultimately estimated may differ materially from the SRK exploration target.

There are currently no mineral resources or mineral reserves at Mangueiros Main, and there can be no assurance that the work underway will result in establishing an initial mineral resource.

Stephen Goodman CEO and Director of the Company further commented: “The potential target size and nickel in sulphide grades as reported are compelling when assessing the nickel content as part of development potential of the asset. The MRE is expected to include copper and cobalt providing the potential to improve the characteristics for a potential development. We look forward to presenting the contributions that copper and cobalt mineralization will have in assessing the development opportunity.”

As described in the SRK technical report, mineralization at Mangueiros Main extends approximately 1,800 metres northwest to southeast, 600 metres southwest to northeast and approximately 250 metres in thickness, and the target remains open in several directions.

The Company believes that the substantial exploration target provides a credible basis to aggressively advance the asset through technical studies with a focus on evaluating the potential development opportunity. The Company is focused on building the next sulphide nickel copper cobalt + PGM mine in Bahia State, Brazil.

The sulphide nature of the mineralization is particularly important, as it is typically associated with conventional processing routes and lower carbon intensity relative to laterite deposits, reinforcing the Project’s alignment with Environmental, Social and Governance (“ESG”) and downstream supply chain requirements.

Corporate Objectives & Advancement Strategy The Company’s objective is to build a sulphide nickel copper cobalt + PGM mine and advance its asset portfolio to establish a new critical minerals district in Bahia State, Brazil.

The near-term strategy to achieve this objective is to:

Complete the initial NI 43-101 MRE for Mangueiros Main including evaluation of potential copper and cobalt mineralization

Following completion of the MRE, evaluate the appropriate scope and timing of further technical studies, including a potential preliminary economic assessment (“PEA”) and feasibility study (“FS”)

Review the historical gravity data and other work completed across the Company’s broader portfolio, specifically Mangueiros West, located ~1 Km from Mangueiros Main to assess district scale opportunity

Recent Brazil Site Visit Supports Advancement Planning for Potential Development During a recent site visit and meetings with stakeholders including strategic shareholders in Brazil, management conducted field reviews, reviewed historical exploration information and assessed regional infrastructure relevant to assessing Mangueiros Main as a development opportunity.

The Company also met with a renewable energy provider to better understand potential for a green power-supply to operate a mine. Any future mining or processing operation, including its power requirements and environmental attributes, would be subject to further technical studies, permitting and other approvals.
