Internal pre-economic assessment of large scale production across the portfolio

Xstreco is carrying out an internal pre-economic assessment of large scale production at each of our five mineral assets, together with the concentration and refining capacity that would process the material. The work consolidates our own project documentation and sets out internal capital and operating cost calculations for each asset and for each planned facility, with further review where the work requires it. The assessment covers the long horizon rather than the near one. It is separate from the small scale pilot production being established at our two precious metals properties, which is recorded separately. The processing and refining facilities it covers, and the stage each of them has reached, are set out under Development projects. It is a running process rather than a single exercise, it remains ongoing, and it is updated as further work is completed. This is internal planning work. As a privately held Swiss group, we are not subject to public mineral reporting regimes such as NI 43-101 or JORC. No figures, results or conclusions are published, and no mineral resource or reserve is declared for any asset.
