Restructuring of the Investec Loan Further to the Company’s announcement dated March 3, 2022 the Company and Investec Bank Limited (“Investec”) concluded negotiations regarding the restructuring of the R46,114,971 owing on the Investec Loan, on March 30, 2022. The following salient terms were agreed to: • Monthly capital repayments of R250,000 for March 2022 to June 2022; • Subject to the Group having secured R120 million in funding for the development of the Balgray project, an amount of R6.5 million to be repaid at the earliest of 30 June 2022 or the date on which the funding has been secured; • Monthly capital repayments of R1,250,000 for July 2022 to August 2022; • Monthly capital repayments of R2,500,000 for September 2022 to December 2022; • The final maturity date and date by when the restructuring of the remaining capital balance owing should be agreed to be extended to December 31, 2022; • The Group would be allowed to spend R6.5 million on the development of the Balgray project in the absence of any third-party funding until June 30, 2022; and • The reserve bank account and cash sweeping mechanism will continue. Emma Oosthuizen, the Company’s Chief Executive Officer, commented that “The Resources and Reserves Technical Report Update supports positive confirmation that value can be unlocked from the Group’s Balgray, Magdalena and Aviemore North’s mining projects. The agreement reached with Investec regarding the restructuring of the Investec Loan allows the Group to continue with limited scale development of Balgray whilst discussions with existing and potential new investors are ongoing.” Balgray is the Group’s highest priority project and will extend the Group’s anthracite operations by approximately 7 years and would need to become operational during the first quarter of 2023 to replace the diminishing Aviemore East reserves.” About Buffalo Buffalo is a coal producer in South Africa.
