AI Review Confirms Copper Mineralisation
Botswana Minerals PLC has confirmed copper mineralization on its licences through an AI-assisted review of over a gigabyte of historical exploration data, identifying chalcopyrite in drill core originally drilled for uranium and diamonds. This AI analysis, which processed more than fifty years of legacy reports, has validated the company's copper geological model and points to a concealed mineralized corridor beneath shallow Kalahari cover. The company will now accelerate fieldwork on its northern licences, including re-logging and scanning historical core, while continuing analysis on the southern licences, with all next steps fully funded.

About this update from Botswana Minerals Plc
30 June 2026 Botswana Minerals plc ("Botswana Minerals" or the "Company") AI Review Confirms Copper Mineralisation in Historical Drill Core on Botswana Licences Highlights - Further AI interpretation of historical drilling data has confirmed the Company's copper geological model on its licences, identifying chalcopyrite (a primary copper sulphide) in core from holes originally drilled in the search for uranium and diamonds. This is a material step forward in our exploration programme. - AI identified and connected the copper evidence by analysing more than a gigabyte of legacy reports, some over fifty years old, that had never been integrated into a modern copper model, demonstrating the power of AI to unlock value from vast historical datasets. - The data, including copper and nickel sulphides noted in historic boreholes, points towards a concealed mineralised corridor beneath shallow Kalahari cover within the licences. - Fieldwork will now be expedited on the northern licenses, while analysis continues on the southern licences. Summary Botswana Minerals plc, the AIM- and Botswana Stock Exchange-listed copper and diamond exploration company, announces that an AI-assisted review of historical exploration data has confirmed its copper geological model on the Company's licences, identifying chalcopyrite, a primary copper sulphide, in historical drill core from holes originally drilled in the search for uranium and diamonds. The Company regards this as a material step forward in the exploration of its copper interests. Alongside the primary chalcopyrite, the historical records show altered copper minerals, including malachite and chrysocolla. Together, these directly confirm the AI-generated target corridors and strengthen the model for concealed copper and base metal mineralisation beneath Kalahari cover. The significance of AI in this application is its ability to recover and connect this evidence from more than a gigabyte of records spanning over fifty years and several separate exploration campaigns within a matter of days, work that would be impractical to do manually, turning overlooked legacy data into a focused field programme. John Teeling, Chairman of Botswana Minerals, commented: "This is exactly how AI should work in mineral exploration. The initial AI analysis identified prospective copper corrid...
