Imweru  - Operational Update

Kibo Mining Plc ("Kibo" or the "Company") (AIM:KIBO; JSE AltX: KBO), the Tanzania focused mineral exploration and development company, is pleased to update the market with regard to the latest operational developments at the Company's advanced gold project, the Imweru Gold Project ("Imweru").

Highlights

·    Commencement of Stage 1, Phase 2 (the Pre-Feasibility Study) of the Imweru Definitive Feasibility Study ("DFS") ;

·    Site visit by Qualified Persons ("QP") to the planned Imweru Gold Mine site confirms conclusions and assumptions from Preliminary Economic Assessment;

Louis Coetzee, Chief Executive Officer of Kibo Mining plc, commented: "We continue to make rapid advances in the development of the Company's flagship projects and it is therefore very pleasing to confirm to market the continuation of Feasibility Study work at Imweru, particularly as successful completion of this work is a vital step prior to mine construction and early production in the near term, but also towards securing development funding for the project. 

The Kibo team is committed to maintain and further accelerate the rapid progress we have achieved recently on all of the Company's projects, and the proactive approach to completion of the Feasibility work on both Imweru and the Rukwa Coal to Power Project is welcomed by all the current and prospective stakeholders of Kibo."

Summary of Imweru work to date

Kibo Mining is working progressively through the Feasibility Study required to enable Imweru to move into the construction phase leading to early production in the near term. To date Kibo has undertaken the following feasibility work:

·    JORC Compliant  Competent Persons Report on the Imweru Gold Resource

·    Preliminary Economic Assessment ("PEA") on the gold resource;

Next Steps for the Imweru Feasibility Studies

The next stage of project development work will involve completion of definitive feasibility studies on the multi-pit gold mine, inclusive of the associated environmental assessments and advanced financial modelling for the Imweru Project. The definitive feasibility work will also include securing all related permits and / or rights with the Ministry of Energy and Minerals and other government departments and agencies. Completion of the DFS' will advance Imweru to financial close and early production.

To date, all the required planning and preparation for Stage 1, Phase 2 (the Pre-Feasibility Study, or "PFS") of the Imweru Definitive Feasibility Study has been completed, and the first scheduled work activities of the PFS, comprising primarily of a site visit to the Imweru gold project site, has also been completed. The site visit was conducted by technical experts from Minxcon Projects and the visit confirmed conclusions and assumptions from the PEA.

The Imweru PFS is defined as a comprehensive study of the viability of a range of options that has advanced to a stage at which the preferred pit configuration has been established and an effective method of mineral processing has been determined.

The range of options to be investigated during the MPFS, consist of the following:

·    Owner-operated Mining Option

·    Contractor-operated Mining Option

The Imweru PFS includes a financial analysis based on realistic assumptions of technical, engineering, operating and economic factors and the evaluation of other relevant factors that are sufficient for a Competent Person, acting reasonably, to determine if all or part of the Mineral Resource may be classified as a Mineral Reserve. The overall confidence level of Imweru will be advanced to 70 - 85% from the current 40 - 50%.   

Additional to the Imweru PFS, the potential to expand known mineral deposits and to advance new target areas will be investigated and assessed.
