Mineração Taboca S/A, a leading Brazilian producer of tin and tantalum, has successfully completed third-party verification under Tin Code Assurance, reaffirming its commitment to responsible sourcing. The independent assurance, conducted by PwC included both the Pirapora (tin smelter) and Pitinga (NbTa processing plant) facilities.  

Key Highlights:  

• This verification relates specifically to Standard 7.3 (Responsible Sourcing), one of the 72 environmental, social and governance standards of the Tin Code.   

• Taboca’s due diligence systems and public reporting have been third-party verified against the ITA-RMI Assessment Criteria for Tin Smelting Companies (version 2, 25th March 2021), with the assurance report dated 16 December 2024.  

• Taboca has implemented robust policies and procedures to assess potential risks, avoid support for conflict, human rights abuses, and other significant harms.  

• During the reporting period, 100% of the primary material processed at Pirapora and Pitinga was sourced from Taboca’s own Pitinga mine in Brazil.  

• An independent alignment assessment confirmed standards of the Criteria and Tin Code audit management process are fully aligned to OECD Due Diligence Guidance for Responsible Sourcing of Minerals from Conflict-Affected and High Risk Areas.  

Looking Ahead:  

This rating for Standard 7.3 (Responsible Sourcing) was determined according to the normal Tin Code validation procedure following Taboca’s independent assurance engagement. It will be included in the next scheduled Tin Code Report covering all 72 Standards.
