MANAUS, Brazil, May 06, 2026 (GLOBE NEWSWIRE) -- Brazil Potash Corp. ("Brazil Potash" or the "Company") (NYSE-American: GRO), a mineral exploration and development company advancing the Autazes potash project in Amazonas State, Brazil (the "Autazes Project"), is pleased to announce the award of a Front-End Engineering Design ("FEED") contract for the processing plant, tailings facility, river barge port, and the upgrade of approximately 13 km of road connecting the plant to port, to a consortium of Wood and Promon Engenharia ("Promon").

"Wood's track record in potash and large-scale fertilizer infrastructure, combined with Promon's extensive knowledge of how to build in Brazil, gives us exactly the right consortium to deliver the surface FEED our lenders and partners need to see" said Raphael Bloise, Project Director Brazil Potash.

Wood and Promon were selected for their complementary and directly applicable experience, global potash and fertilizer engineering leadership paired with deep, on-the-ground Brazilian execution capability.

Surface Infrastructure and the Path to Financing

The completion of FEED studies is a critical milestone for securing construction debt financing, which is currently being advanced through active dialogue with Development Finance Institutions and Export Credit Agencies. It converts early assumptions into independently verifiable, investment-grade outputs— providing CAPEX and OPEX accuracy, risk quantification, constructability analysis, and environmental, social and governance (ESG) documentation that lenders require before committing capital.

This FEED also ensures alignment across all interdependent surface systems, processing throughput, water balance, power demand, tailings capacity, and port logistics, under a single, coherent engineering framework.

Wood: Potash and Fertilizer Engineering at Global Scale

Wood is a global leader in consulting, engineering and operations for the energy and materials sectors. Their portfolio of relevant project experience includes serving as engineering contractor for K+S's Bethune potash mine in Canada, one of the most significant fertilizer developments of the past decade, and multiple Canadian and international potash project expansions exceeding 8 million annual tonnes of production. Wood brings proven capability across the full spectrum of surface infrastructure required at Autazes.

Promon Engenharia: Brazilian Engineering and Construction Expertise

Promon Engenharia is one of Brazil's most established engineering and project management companies, with more than six decades of experience executing complex industrial and mining projects across the country, including involvement in some of Brazil's largest fertilizer developments. With a client base that includes Brazilian and international mining operators, and a strong track record in Northern Brazil, Promon Engenharia brings Brazilian-domiciled engineering and EPCM capabilities that are essential for project execution in Amazonas State.

Promon Engenharia's contribution to the consortium includes ensuring full compliance with Brazilian engineering standards and construction regulations, integrating with local supply chains and labor markets, and producing designs compatible with Brazilian environmental licensing, permitting processes, and logistical realities, helping reduce execution risk and supporting the delivery of value-creating solutions for clients.

About Brazil Potash

Brazil Potash (NYSE-American: GRO) (www.brazilpotash.com) is developing the Autazes Project to supply sustainable fertilizers to one of the world's largest agricultural exporters. Brazil is critical for global food security as the country has amongst the highest amounts of fresh water, arable land, and an ideal climate for year-round crop growth, but it is vulnerable as it imported over 95% of its potash fertilizer in 2021, despite having what is anticipated to be one of the world's largest undeveloped potash basins in its own backyard. The potash produced will be transported primarily using low-cost river barges on an inland river system in partnership with Amaggi (www.amaggi.com.br), one of Brazil's largest farmers and logistical operators of agricultural products. With an initial planned annual potash production of up to 2.4 million tons per year, Brazil Potash's management believes it could potentially supply approximately 20% of the current potash demand in Brazil. Management anticipates 100% of Brazil Potash's production will be sold domestically to reduce Brazil's reliance on potash imports while concurrently mitigating approximately 1.4 million tons per year of GHG emissions.
