FOR IMMEDIATE RELEASE – New Submissions to Canadian and U.S. Securities Commissions Allege Proposed Canadian Mine in the Brazilian Amazon Has Misrepresented Risks to Investors

Tuesday, May 5, 2026

TORONTO – University legal clinics have filed separate requests with securities commissions in Canada and the U.S. to investigate misrepresentations by a Canadian company seeking to mine for potash in the Brazilian Amazon. 

The requests to the Ontario Securities Commission (OSC) — filed by the University of Toronto Jackman Law’s International Human Rights Program (IHRP) — and U.S. Securities and Exchange Commission (SEC) — filed by the Cardozo Law Institute in Holocaust and Human Rights (CLIHHR), respectively — submit that Canadian company Brazil Potash is not adequately informing investors of the risks of its mining project. 

“In the IHRP’s view, the company’s mining project not only presents a great risk to the people and ecosystems of the Amazon but may also present a danger to investors,” said IHRP Director Sandra Wisner. 

The requests submit that Brazil Potash has allegedly failed to disclose and misrepresented serious legal, social, and environmental risks of the Autazes Project. The requests draw extensively upon interviews conducted with Mura Indigenous community members and leaders in villages located near planned mining infrastructure sites and expected to be among the most severely affected by the project. Brazil Potash’s Autazes Project is the subject of ongoing lawsuits in Brazil, including a civil action to compel the formal demarcation of the land on which the Autazes Project is located as Indigenous land. If demarcation is successful, it may render the mine’s license to operate invalid.  

“At stake for my community is the destruction of our core ways of life and deep spiritual connection to the land as Mura peoples” said Filipe Gabriel Mura, Chief of the Mura community of Lago do Soares. “Lago do Soares remains steadfast in our demands for official demarcation of our territories as provided by the Brazilian Constitution and for an end to Brazil Potash’s Autazes Project.” 

The U.S. $2.5 billion mining project, meant to extract and refine sylvinite from the Amazon River into potash, the principal ingredient in fertilizer, began exploratory drilling as early as 2010 and is currently under development.
