NI 43-101 Refile: Bilboes Gold Feasibility Report

Summary by AI ^BETAClose X

Caledonia Mining Corporation Plc has refiled its Bilboes Gold Project National Instrument 43-101 Technical Report on SEDAR+ due to identified issues with qualified persons listed by DRA Projects (Pty) Ltd, which has been rectified by replacing authors to meet regulatory definitions. This update, titled "Bilboes Gold Project Matabeleland Zimbabwe National Instrument 43-101 Technical Report," does not alter the project's feasibility study under US mining disclosure rules, as DRA can act as the sole qualified person, and therefore has no impact on the Bilboes Gold Project itself.

Refiling of Bilboes Gold Project Feasibility Study National Instrument 43-101

Technical Report

(NYSE AMERICAN: CMCL; AIM: CMCL; VFEX: CMCL)

St Helier, 22 May, 2026: On November 24, 2025, Caledonia Mining Corporation Plc (the "Company") filed the "Bilboes Gold Project Technical Report Summary" with effective date October 31, 2025 prepared by DRA Projects (Pty) Ltd ("DRA") on EDGAR as an exhibit to a Form 6-K Report of Foreign Private Issuer (the "Feasibility Study").

In accordance with Canadian securities regulations, the Company then filed on January 6, 2026 the "Bilboes Gold Project Feasibility Study National Instrument 43-101 Technical Report" with effective date October 31, 2025 prepared by DRA on SEDAR+ (the "Canadian Report ").

Staff at the Ontario Securities Commission (the "OSC") have reviewed the Canadian Report and identified that some of the authors listed by DRA as qualified persons in the report did not meet the definition of a qualified person under National Instrument 43-101. DRA has therefore updated the Canadian Report by replacing those authors with individuals that meet the definition of a qualified person, and the updated Canadian Report, which is entitled "Bilboes Gold Project Matabeleland Zimbabwe National Instrument 43-101 Technical Report", was filed on SEDAR+ yesterday.

Under US mining disclosure rules, DRA is able to act as the sole qualified person and therefore the Feasibility Study is unchanged. For the avoidance of doubt, there is no effect on the Bilboes Gold Project and the aforementioned change is solely to comply with Canadian mining disclosure rules.
