With the fundraise approved, we have the funding in place to take the mine through construction to first production. I would like to thank our shareholders for their support, and in particular the National Wealth Fund, Vision Blue Resources, Glencore and Leonidsport, whose commitment reflects the strategic value of a long-life tin asset at a time when new supply is scarce. “From here, our focus is on delivery, building South Crofty safely, on schedule and within budget, and bringing new tin from an old mine. I am also very pleased to welcome Kyril Louis-Dreyfus to the Board. Kyril joins us at an important moment, and his family’s long-term approach to investment fits well with a project of this scale and life.” Appointment of Mr. Kyril Louis-Dreyfus to Cornish Metals’ Board of Directors Leonidsport B.V. has nominated Mr. Kyril Louis-Dreyfus as its representative to the Board of Directors of the Company.
