Independent ESG Assessment
Independent, third-party review of our ESG and sustainability practices and objectives is a key component of our commitment to creating long-term value for all our stakeholders through integrating ESG best practice into the ongoing development of the Company.
Since 2021, Marimaca has completed an annual independent ESG performance assessment via the Digbee ESG reporting framework, to evaluate Company and project ESG credentials. The Digbee framework assessment includes the completion of a set of comprehensive corporate and project questionnaires appropriate to the scope of the Marimaca project and mapped to key Global Standards. The assessment required the provision of relevant corporate and project data, narrative and supporting evidence. Our disclosure was board-approved prior to submission and assessed by independent mining ESG experts to produce an impartial rating, resulting in a specific ESG certification. Scores are also peer-reviewed as part of the assessment, to ensure accuracy and credibility.
The full 2025 report can be found here.

Building a Sustainable Project
In 2024, the Company dedicated a significant amount of time and resources to develop the Environmental Impact Declaration (DIA) for the Marimaca project. The DIA was submitted in January 2025, paving the way for a more robust Environmental Impact Assessment System (SEIA) in the future.
Marimaca prioritised the DIA ahead of a Feasibility Study to better define environmental and stakeholder concerns in the mine design. The proposed electricity plant seawater recycling plan permits have been obtained, thus ensuring the future mine will not draw water from the arid environment.
The Company demonstrates sound Corporate Governance practices and conducts regularly independent financial audits, Board member skills assessments, and formalizes governance frameworks. It also maintains a project specific website with relevant information for stakeholders.
Marimaca has refined its environmental protections including archaeological/ palaeontological site safeguarding, has finalised a community engagement plan, has established a social investment fund, and upheld its commitments to local recruitment, procurement, and support of educational programmes.
