Lansdowne Resources is a mineral exploration and development company focused on identifying, acquiring, and advancing high-quality mineral assets. The Company's principal asset is São Gabriel Mineração Ltda ("Sao Gabriel Mining") in Brazil, which provides exposure to critical minerals with significant exploration and resource growth potential. Following the reverse takeover of Lansdowne Oil & Gas plc, the enlarged entity will be renamed Lansdowne Resources and will operate primarily in Brazil, leveraging technical expertise and local operational presence to develop and expand its mining portfolio.

The Company's strategy is to build value through exploration, evaluation, and, where appropriate, development of mineral assets. Lansdowne Resources aims to advance the Sao Gabriel Mining project through geological assessment, drilling, and resource definition, alongside evaluating additional complementary acquisitions and strategic opportunities within the natural resources sector. The business model emphasizes disciplined capital allocation and value creation for shareholders.

The Company's operations are structured to benefit from Brazil's established mining regulatory framework, with a focus on sustainable and responsible resource development. Lansdowne Resources intends to adopt international best practices in environmental, social, and governance (ESG) matters, ensuring long-term operational and community alignment.

Admission to trading of the enlarged entity's shares on AIM is sought as a result of a reverse takeover under AIM Rule 14, with the acquisition of Sao Gabriel Mining constituting a fundamental change to the Company's business.
