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.

Company is focused on exploration and development of mineral projects in Tanzania, and
controls one of Tanzania's largest mineral right portfolios. Tanzania provides a secure and
stable operating environment for the mineral resource industry and Kibo Mining therein.
Kibo Mining holds a thermal coal deposit at Rukwa, which has a significant JORC compliant
defined resource (See Table 1 below), and is developing a 250-350MW mouth-of-mine thermal
power station with an established management team that includes Standard Bank as Financial
Advisor. Kibo is undertaking a Coal Mining Definitive Feasibility Study and a Power Pre-
Feasibility Study for Rukwa with initial findings to be released in the near term.
The Company also has extensive gold focused interests including Lake Victoria Goldfields and
Morogoro projects. At Lake Victoria, the Company has projects with a 550,000oz JORC
compliant gold Mineral Resource at Imweru Project (See Table 2 below) and a 168,000oz NI
43-101 compliant gold Mineral Resource at Lubando Project (See Table 3 below) in which the
Company holds a 90% attributable interest. The Company is currently undertaking a Definitive
Feasibility Study on its Imweru Project, with Preliminary Economic Assessment study findings
to be released in the near term.

interest in the Imweru and Lubando Mineral Resources shown in Table 2 and 3 above), with Barrick having
a 10% carried interest up to a decision to mine at which point they have to contribute or be diluted to a 2%
net smelter royalty. BEAL also has a first right of refusal pursuant to which they can buy the 90% interest
in the project at an agreed market related value after completion of a Bankable Feasibility Study. Kibo
remains the operator of the project.
