Bahia Metals Corp: Bahia Metals Technical Review Reinforces the Potential of the Mangueiros Main Project

VANCOUVER, British Columbia, July 27, 2026 (GLOBE NEWSWIRE) — Bahia Metals Corp. (CSE: BMT) (“Bahia” or the “Company”) is pleased to provide an update on its corporate strategy and ongoing technical review of the Mangueiros Main Nickel-Copper-Cobalt-PGM Project and regional exploration projects (the “Projects“) in Bahia State, Brazil.

The review has reinforced management’s view that the Mangueiros Main project (“Mangueiros Main“) possesses many of the characteristics associated with a development-stage nickel sulphide asset, including significant scale potential, extensive historical drilling, encouraging preliminary metallurgical results and access to established infrastructure within one of Brazil’s premier mining regions.

The Company’s flagship asset, Mangueiros Main is a technically well understood, sulphide-hosted nickel-copper-cobalt-PGM project with an exploration target of 75-200 Mt @ 0.20% to 0.25% NiS¹ with the potential to emerge as a strategic, long-life source of critical minerals. It is located in Bahia State, Brazil, a well-established mining jurisdiction with infrastructure, supportive regulatory frameworks, and a strong mining tradition. This combination positions Mangueiros to contribute to future supply chains supporting electrification and energy transition technologies.

Stephen Goodman, CEO and Director of Bahia Metals Corp. comments:
“Mangueiros Main represents a strong critical minerals exploration opportunity. As stated, our objective is to efficiently unlock the potential of Mangueiros Main through resource definition and economic evaluation.

Mangueiros Main benefits from a substantial technical foundation, including extensive drilling, geophysical surveys and encouraging preliminary metallurgical work. As we continue our review, we believe Mangueiros Main is emerging as a compelling nickel sulphide opportunity in a jurisdiction that is attracting global investment in critical minerals.

Beyond Mangueiros Main, we see meaningful growth potential across our broader asset portfolio. Mangueiros West, located just 1 km away, is emerging as a compelling follow-up opportunity and is expected to be a key focus as we continue advancing the district.

The Company is focused on creating long-term shareholder value through disciplined technical advancement of its assets.”

Mangueiros Main: The Foundation of a Future Critical Minerals Hub in Bahia State
Mangueiros Main represents the Company’s flagship asset and is the most advanced target. It serves as the cornerstone asset within what management believes could evolve into a broader district-scale nickel camp.

Drilling at Mangueiros Main has confirmed a broad, continuous zone of nickel-copper-cobalt sulphide mineralization extending across a footprint measuring at least 2,000 meters in strike length and approximately 500 meters in width. Importantly, mineralization begins at surface, a characteristic that may support favourable future development scenarios.

The Company benefits from an extensive technical database that includes approximately 12,786 meters of diamond drilling in 86 holes across the Projects, including 10,005 meters of drilling at the Mangueiros Main and adjacent targets and includes multiple geophysical datasets.

This technical foundation allows the Company to rapidly transition from exploration toward resource definition and project advancement.

Technically Well Understood Asset

• Drilling at Mangueiros Main confirmed a shallow, laterally continuous and predictable mineralized system

Potential Scale

• Mineralization defined over ~2.0 km strike length, widths up to 500 meters, and depths of up to 300 meters

Defined Exploration Target

• 75-200 million tonnes grading 00.20%-0.25% NiS1, as outlined in the Company’s NI 43-101 Technical Report prepared by SRK Consulting

*The potential quantity and grade is conceptual in nature. There has been insufficient analysis of existing exploration data to define a mineral resource and that it is uncertain if such analysis of existing data or further exploration will result in the target being delineated as a mineral resource. The potential quantity and grade is based on existing historical data as described above.

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 evolving ESG and downstream supply chain requirements.

Preliminary metallurgical work on mineralization at the Mangueiros Main target was completed in 2023¹. Four individual metallurgical samples of approximately 33 kg each was collected from drill core crushed rejects (3 mm) from eight drill holes and were composited. Results of the test procedure demonstrated encouraging recoveries for nickel, with NiS recovery from 81.2% to 91.5% for blebs sample and 79.7% to 81.9% for disseminated samples. The SRK technical report¹ recommends additional metallurgical testing to expand and refine nickel recoveries and greater visibility into recoveries for other metals.

Mangueiros West Highlights
The Company is advancing its high-priority target at Mangueiros West, ~1 km from Mangueiros Main.

Table 1. Drill results from Mangueiros West, drill hole MGDG-069

Note: Hole MGDH-069 ended in mineralization; the true thickness and extent of the zone remains open. All reported intervals are downhole lengths and the true thickness cannot be established without additional drilling.

• Geophysical signature comparable in scale and intensity to Mangueiros Main
• Encouraging intercepts of sulphide nickel-copper-cobalt mineralization

This supports Bahia’s view that there is potential of a district-scale mineral system.

Corporate Strategy and Development Roadmap
Advance Mangueiros Main through key technical milestones designed to enhance the Project’s understanding and support future development decisions.

Subject to the results of the ongoing technical review and available funding, the Company’s current objectives include:

• Advancing work toward an initial NI 43-101 Mineral Resource Estimate (“MRE”) for Mangueiros Main
• Continuing technical evaluation of the Mangueiros West, Lagoa da Onça and Lagoa da Onça North targets to assess their contribution to the broader district-scale potential of the Projects
• Advancing metallurgical, geological and engineering studies to support future technical decision-making
• If these steps prove successful, evaluate the potential scope and timing of a NI 43-101 Preliminary Economic Assessment (“PEA”)

Sampling, QA/QC, and Analytical Procedures
Bahia Nickel Mineração drill core (HQ – 63.5 mm) was recovered and site, quick logged, sealed and transported to the core facility located in the city of Campo Alegre de Lourdes where geologists and technicians would inspect and sign off on the delivered core. Drill core was then logged and marked up for sampling based on geological features and sulphide concentration and a center line was established prior to cutting. Drill cores were sawn in half, with one half remaining in the core box and the other half secured into new plastic sample bags with unique sample number tickets. Samples where packed into PVC bags (no more than 5 per bag) and were dispatched to the laboratory by a nationally recognized courier service every two weeks during the drill campaign. All reported samples were prepared at the ALS preparation facility located in Vespasiano, MG, Brazil and shipped to the ALS laboratory in Callao, Peru for analysis. Samples were oven dried, crushed to 70% passing 2 mm and then pulverized to grind size of 85% passing 75 microns. Method ALS Code NI-ICP05 was utilised for nickel analysis and multi-analysis digestion (ALS Code ME-ICP61) was used for the other elements with ICP-AES finish, providing total nickel content. PT, Pd and Au were analysed by fire assay with ICP-AES finish (ALS Code PGM-ICP23). QA/QC procedures for the drill program include the insertion of certificated standards, blanks and laboratory duplicates per batch (one batch contained only one drill hole). All QAQC control samples returned values within acceptable limits.

The ALS preparation facilities and assay laboratories are independent. ALS assay laboratories are ISO 17025 accredited. All ALS South American sample preparation facilities are included in the scope of the ISO audit for the Lima assay laboratory and thus are also ISO 17025 accredited.
