Power Pre-Feasibility Study Report - Rukwa Coal to Power Project

Kibo Mining plc ("Kibo" or the "Company") (AIM: KIBO; AltX: KBO), the Tanzania focussed mineral exploration and development company is pleased to announce the findings from the Power Pre-Feasibility Study ("PPFS) report for the Rukwa Coal to Power Project ("RCPP").

Key Highlights

The PPFS report was prepared by Aurecon on behalf of the Company and findings include the following:

-    four plant configurations were assessed, with a base case technology comprising 2 x 150MW Circulating Fluidised Bed (CFB) recommended for further development in Feasibility;

-    sufficient additional coal resources are available from Rukwa to potentially expand the power station to double the current design size or to be used in alternate energy conversion technologies such as coal to liquids;

-    a technical and environmental risk assessment was undertaken which unanimously recommended further development of the project via feasibility analysis;

-    total project cost, dependent on the plant option selected, is estimated between US$640 million and US$760 million;

-    modelling was undertaken based on conservative "base-load" assumptions (80% capacity factor) to predict annual generation profiles over the plant life. Indicative annual power generated, dependent on plant option selected, will be between 1,841GWh per annum and 1,877GWh per annum.

Based on the parameters discussed above, the Company has decided to proceed with the definitive feasibility stage of the Power Definitive Feasibility Study ("PDFS") as recommended by Aurecon. Drawing relevant data from the PPFS and the Definitive Mining Feasibility Study: Phase 1, Stage 1 Report, the Company also prepared an internal preliminary financial model as a base case financial model, to be verified in respect of the 300MW power plant and coal mine base case, during the ensuing definitive feasibility studies. Publication of detailed financial information on the RCPP is at present commercially sensitive, based on early stage assumptions with regard to power generation volumes, pricing, capital and operating costs and therefore not ready for public dissemination. Highlights of the indicative base case financial model which Kibo has used to inform its decision on whether to proceed with the definitive feasibility stage of the PDFS include:

-     Indicative power generation revenues, over an assumed 25 year plant operation, of approximately US$7.8 to US$8.4billion;

-     Indicative pre-tax equity IRR in excess of 23%;

-     Indicative post-tax payback of approximately 8 to 9 years;

-     Indicative project NPV range at a 15% discount rate of US$230 to US$280 million.

The preliminary financial model and information discussed above, comprises the Company's internal financial base case for the RCPP. This base case will now be provided to the Company's independent financial and technical advisors on the RCPP, for proper assessment, evaluation, validation and adjustment during the definitive feasibility study stage of the PDFS. The commercial and financial figures discussed above should therefore not in any way be construed as a financial forecast of any kind.

Louis Coetzee, CEO of Kibo Mining plc said "This Power Pre-Feasibility Study work represents an acutely critical part of the RCPP.  We are delighted that the report received demonstrates the robust nature of the project from a technical perspective.  The purpose of the PPFS is, in part, to identify any major technical flaws that could be project fatal.  This report has confirmed no such flaws were identified.

We are particularly pleased with project robustness, because the RCPP is a clear opportunity for Kibo to assist the Tanzanian government in its striving for energy solutions to address the energy supply deficit in Tanzania.  Access to power provides enhancement to everyday life domestically and commercially.  This project above all can deliver safe and reliable base-load power to the Tanzanian people and commercial enterprises benefitting the national socio-economic development plan. The RCPP is a strategic catalyst for the economic development regionally as well as nationally and hence our resolute drive to successfully complete this coal/power project.

Notwithstanding societal benefit, any commercial development of this magnitude must have robust financials and project economics.  This has rightly been made all the more challenging by our desire to offer cost effective power for users. The data currently available from the Definitive Mining Feasibility Study report, a summary of which was released to market on 11^th December 2014, is now supplemented by the data we have gathered from the Power Pre-Feasibility Study and associated internal financial modelling. Indicative project revenues, capital payback, deliverable margin estimates, free cash flow forecasts, project NPVs and IRR estimates appear to be attractive for both the Company as well as its potential clients.  In our opinion this is best illustrated by our base case IRR data which highlights a pre-tax equity IRR in excess of 23%, which is substantially above levels of return which have attracted investment in the past and the average IRR for similar projects in the same geographic area where the RCPP will be located. 

The technical quality and financial robustness of the project were expected to be very strong, but the reports received have still exceeded expectations.  As a result, the intensity and nature of partner discussions have intensified with a considerable degree of justifiable competitive tension as a consequence".

Important Notes for Readers

We would refer readers to our Definitive Mining Feasibility Study announcement of 11^th December 2014 and the Executive Summary Report published on our website covering the Phase 1, Stage 1 Report dealing with the mining component of the RCPP.

We would ask readers to note that the Company is engaged in highly confidential discussions with various parties, including regulatory authorities, for whom the release of detailed financial information may cause a breach of confidentiality and normal commercial sensitivity and may therefore harm the Company's ability to complete negotiations on the best terms for shareholders.

The specific financial information provided is an extract from an early stage economic assessment of the RCPP made for the purposes of deciding whether to extend the study work undertaken on the RCPP to date. The economic assessment is based on input assumptions which will require extensive testing and are likely to be subject to significant change as the feasibility study process progresses.

Kibo Mining - Notes to editors

Kibo Mining is listed on the AIM market in London and the AltX in Johannesburg. The 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 NI43-101 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 with Stage 1 Phase 1 positive results now released and a Power Pre-Feasibility Study for Rukwa with initial positive findings already released.  The Company is now engaged with a number of major Independent Power Producers and other organisations and seeking to secure a commercial partnership or partnerships, to finalise feasibility work across the project and move toward the construction phase.

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. As part of the Kibo Gold Portfolio, Kibo also holds the Morogoro Gold project where the company is seeking a Joint Venture partner to continue active exploration activities at this highly prospective opportunity.
