African Consolidated Resources plc ("AFCR" or "the Company")
Declaration of a 1.02 million ounce Ore Reserve Estimate
and
Updated Mineral Resource Estimate
and
Clarification of previous information
and
Corporate Update
African Consolidated Resources PLC, the AIM listed resources and development company, is pleased to announce the confirmation of an Ore Reserve Estimate in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, 2012 Edition ("the 2012 JORC Code") of 16.6Mt grading at 1.9g/t for 1.02Moz of contained metal at its flagship Pickstone Peerless Gold Project in Zimbabwe ("Pickstone-Peerless"). Minxcon was retained as the Competent Person under the 2012 JORC Code to compile an estimate for the Ore Reserve.
The Company also announces an updated Mineral Resource Estimate on Pickstone-Peerless in accordance with the 2012 JORC Code supporting the Ore Reserve Estimate. This is in line with company policy to report the Reserve estimate as a subset of the Mineral Resource. The declared Resource is 62.0Mt at 1.8g/t containing 3.56 Moz at a cut-off grade of 0.3g/t down to 250 metres below surface (open pit) and at 1.5g/t for the remaining resource below 250 metres below surface. ExplorMine was retained as the appointed Competent Person under the 2012 JORC code to compile and estimate the Company's resources.
These upgraded Reserves and Resources have been developed from the Pre-Feasibility Study ("PFS") carried out by AFCR and as announced on 4 December 2013.
In addition, the Company wishes to clarify certain information previously given for the benefit of investors and shareholders and provide a general corporate update.
Pickstone-Peerless Ore Reserve Estimate:
Key Highlights:
A total Ore Reserve Estimate of 1.02 million ounces @ 1.9 g/t based on a gold price of USD 1,300/oz and a cut-off grade of 0.4g/t
The Ore Reserve Estimate is based on designed open pits down to a depth of approximately 220 metres for the Peerless open pit and 250 metres for the Pickstone open pit
2012 JORC Ore Reserve Statement compiled by independent consultants Minxcon Pty (Ltd); this follows the PFS developed by AFCR and the provisional Reserve declaration by AFCR of 1 million ounces, both as released on 4 December 2013.

The Ore Reserves have been estimated and compiled under the direction of Mr. Daniel van Heerden who is a Fellow of the South African Institute of Mining and Metallurgy ("FSAIMM") and a member of various professional organisations as publicised in a list by the Australian Securities Exchange ("ASX"). Mr. van Heerden has sufficient experience relevant to the style of mineralisation, type of deposit under consideration and for the activity being undertaken to qualify as a Competent Person as defined by the 2012 edition of the 'Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves'. Mr. van Heerden consents to the inclusion in the report of the matters based on their information in the form and context in which it appears.
AFCR wishes to clarify that the reserves table previously published on the Company's website erroneously omitted that it was a provisional reserve estimate, pursuant to the announcement of 4 December 2013.
The full Ore Reserve Report prepared by Minxcon with an effective date of 1 November 2013 shall today be published on the Company's website. In addition, the Executive Summary of the report has been extracted into Appendix 1 to this announcement. It should be noted that the Financial Valuation at paragraph 1.5 of Appendix 1 is the valuation of the base line case as referred to in the PFS Executive Summary announced on 4 December 2013. AFCR's preferred option (Option 12) in the PFS Executive Summary gives a higher valuation.
Updated Pickstone-Peerless JORC Resource estimate:
The ExplorMine Competent Persons Report ("CPR") detailing the June 2013 Mineral Resource Estimate for the Pickstone-Peerless Gold Project has been updated by ExplorMine Consultants with an effective date of December 2013 in accordance with the 2012 JORC Code. A 'soft boundary' between the higher grade 'inner zone' and the lower grade 'outer zone' at Pickstone has been utilised and has resulted in a 2.2% increase in total Mineral Resources when compared on the same cut-off grades as the June 2013 CPR.
In addition, economic findings detailed in the PFS Report and the JORC Ore Reserve Estimate, in which the Ore Reserve Estimate for the open pit has been calculated at a cut-off grade of 0.4g/t, has resulted in the Resource Estimate being updated by ExplorMine to reflect the Mineral Resource Estimate at a cut-off grade 0.3g/t for both the Peerless and Pickstone open pits. The change of cut-off grade is due to more precise technical and economic conclusions derived from the PFS. The underground cut-off grade has been maintained at 1.5g/t for both the Peerless and Pickstone Mineral Resources.
As a result of this, the Mineral Resources have increased in all resource categories and from a total of 39.96 Mt at 2.5 g/t for 3.21 Moz at a cut-off grade of 0.5g/t (Pickstone) and 0.6g/t (Peerless) as at June 2013, to now 62.0Mt at 1.8 g/t for a content of 3.56 Moz at a cut-off grade of 0.3g/t down to 250 metres below surface (open pit) and at 1.5g/t for the remaining resource below 250 metres below surface.

The full ExplorMine Competent Persons Report, which incorporates the above Mineral Resource Statement shall today be published on the Company's website. In addition, an extract from the CPR of the full summary estimation of the Mineral Resources (section 1.4) and the summary Conclusions and Recommendations (sections 1.5 and 1.6) is detailed in Appendix 2 to this announcement.
Clarification of previous information:
Due to the number of different reports that have been issued since November 2012 as the understanding of the Pickstone Peerless ore body has grown, the Company believes it appropriate and helpful to make clear where the Company has taken responsibility itself, through its team of employed Competent Persons (in accordance with the JORC Code) and other qualified employees, and where the Company has retained and relied on third party experts.
The table below shows the various responsibilities, the announcement date and location of relevant reports for the Preliminary Economic Assessment (14.11.12); JORC CPR (15.07.13); DFS (15.07.13); JORC Ore Reserve (15.07.13); audit by SRK/Camisani of Resources (30.09.13); outcome of PFS and Executive Summary (04.12.13); and Ore Reserve (today).

Pursuant to the announcement of the DFS of 15 July 2013 (the "DFS Announcement"), Basil Read Matomo ("BRM") had been appointed lead contractor for the DFS and had been intended to remain as such for the PFS. However, following a dispute between the Company and BRM, which was not connected in any way with the results of the DFS, the relationship with BRM was terminated in August 2013. The Company wishes to clarify that whilst BRM contributed to plant design and construction pursuant to its contract, the Company is responsible for the authoring of the DFS and also sought third party assurances on work undertaken by BRM from Minxcon and others; that Minxcon was the Competent Person for the Ore Reserve; and that ExplorMine was the Competent Person for the Ore Resource. In authoring the DFS, the Company's team of employed Competent Persons (in accordance with the JORC Code) and other qualified employees worked closely and directly with Minxcon. Minxcon reviewed the DFS and has confirmed that the study is of adequate quality and level of detail to be used to conduct a 2012 JORC-compliant Ore Reserve estimation.
Similarly, in authoring the subsequent PFS, the Company's team of employed Competent Persons (in accordance with the JORC Code) and other qualified employees worked closely with Minxcon. Minxcon also reviewed the PFS and has confirmed that the study is of adequate quality and level of detail to be used to conduct a 2012 JORC-compliant Ore Reserve estimation.
The DFS and PFS used the terms "Mineral Inventory", "Mining Inventory" and "Diluted ounces" which are not defined by the JORC Code but are deemed by the Company to be industry accepted terms. However, the announcements of the DFS and PFS did not incorporate the following definitions for such terms, which are detailed below:
Mineral Inventory | The total mineral Resources (Measured, Indicated and Inferred) contained within a defined mining unit on an in-situ (undiluted) basis |
Mining Inventory | The total mineral Resources (Measured, Indicated and Inferred) contained within a defined mining unit on a diluted basis based on 'modifying factors' as per the JORC code |
Diluted ounces | Gold ounces contained within in-situ ore the quantum of which have been diluted by application of the 'modifying factors' as per the JORC reporting code |
Corporate Update:
Nkombwa Hill (Zambia)
Galileo Resources Plc ("Galileo"), which is financing AFCR's Joint Venture ("JV") on the Nkombwa Hills Rare-Earth ("REE") and Phosphate project in NE Zambia, has advised AFCR that it will be relinquishing its interest in all greenfield projects, including Nkombwa Hill.
Galileo was earning an interest by funding exploration expenditure on the JV between AFCR and Australian-based Rare Earth International ("REI"). The REI/Galileo group is committed to spend US$1.35 million by Q4 2014 in order to define a JORC-Indicated REE Resource. Communication concerning termination of the JV is ongoing.
AFCR is highly encouraged by the extent and grades of the REE surface sampling in 2013, and the JV has already established a water bore and a track to the mountain summit, in order to commence drilling in the onset of the Zambian dry season.
With the departure of Galileo, AFCR is actively seeking new partners to progress the REE and Phosphate exploration on this major mineralised carbonatite complex.

The Company is pleased to inform shareholders that it is currently undertaking a due diligence exercise with a major African bank with which a term sheet was signed in 2013. The term sheet provides for a debt facility to fully finance the expansion of the mine to 50,000 tonnes per month, subject to customary due diligence, credit committee approval and also to AFCR securing equity for the initial plant construction.
The Company is now engaging with a number of interested parties to raise USD 30 million for Phase 1 construction as required by the term sheet as a pre-condition to debt-financing the project. The Company is therefore also facilitating due diligence exercises with parties who have expressed bona fide interest in this respect.
A detailed indigenization plan has been drafted and its submission to the relevant Zimbabwean authority is imminent. By regulation, the indigenization authority has 45 days to approve or reject the submission from the date of submission.
Funding
The cash balance at 31 January 2014 was $1.85 million (unaudited) and as reported in the Interim Results further funding will be required in Q2 2014 in order for AFCR to both continue operating as a going concern and develop its Pickstone-Peerless Gold Project together with its portfolio of high impact assets. Discussions are in progress in relation to additional equity funding.

Indicated mineral resource | An 'indicated mineral resource' is that part of a mineral resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed. |
Inferred mineral resource | An 'inferred mineral resource' is that part of a mineral resource for which tonnage, grade resource and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be limited or of uncertain quality and reliability. |
in-situ | material in the ground which has not been diluted or had losses applied to it |
JORC | Joint Ore Reserves Committee of the Australasian Institute of Mining and Metallurgy |

1.5 FINANCIAL VALUATION
Minxcon's in-house Discounted Cash Flow ("DCF") model was used to illustrate the net present value ("NPV") for the operation in real terms. The NPV is derived from post royalties and tax, pre-debt real cash flows, using the techno-economic parameters, commodity price and macro-economic projections. The project valuation summary is described in the following table.
Project Valuation
Real Discount Rate | Unit | Project |
NPV @ 0.00% | USDm | 279 |
NPV @ 5.00% | USDm | 176 |
NPV @ 10.00% | USDm | 112 |
NPV @ 15.00% | USDm | 71 |
NPV @ 20.00% | USDm | 45 |
IRR | USDm | 41% |
For the purpose of the DCF, the company has taken into consideration the full mineable resource life. The Project has a mining LoM of 12 years and a plant treatment life of 26 years. The first financial year is from January 2014 to December 2014.
In order to maximise the grade feed to the plant, the Company decided to decouple the pit from the plant. In order to do so, stockpiles with different grades were modelled which will be fed into the plant to achieve a desirable grade. This was done to generate positive profit:cash margins as soon as possible and to reduce the payback period of the initial capital. As a result of the strategy explained above the cash flows from 2031 are displayed as marginal and is a function of the grade of the stockpiles left behind that will be fed into the plant.
Average payback was calculated from start of first capital expenditure in January 2014 and was calculated at 5.4 years (concluding in May 2019). Peak cash flow is seen during 2026.
[Annual and cumulative Cash Flow graph - see full document on AFCR website]
Based on the real cash flow calculated in the financial model, Minxcon performed single-parameter sensitivity analyses to ascertain the impact on the NPV. For the DCF the gold prices, grade and recoveries have the biggest impact on the sensitivity of the project. Although a large amount of capital is required upfront, the impact on the NPV over the LoM is minimal.

Appendix 2 - Mineral Resource Estimation - ExplorMine CPR extract
1.4 Mineral Resources
A complete estimation of the Mineral Resources has been performed based on a database that has been completely checked and corrected for entry errors. It is intended to perform an evaluation that will give a spatial expression of value distribution, so that the extraction of the primary gold Mineral Resources can be planned efficiently. Hangingwall and footwall mineralisation was also estimated so as to aid Feasibility Study options. Ordinary kriging, for all Mineral Resource categories, was carried out into three-dimensional geological block models for each modelled mineralised zone, which produced a three-dimensional spatial distribution of gold grade in inclined reef structural blocks.

Table IV: Combined Mineral Resource estimate for the Pickstone-Peerless mineralised trends. A 0.3 Au g/t cut-off has been applied for near surface (less than 250 m below surface) material respectively and a 1.5 g/t cut-off has been applied for material deeper than 250 m below surface respectively (tonnes and element kg's have been rounded-off to the appropriate level of accuracy).
Delineation of Mineral Resource category was carried out in the first instance by recording the search volume number utilised in each block on a special run done for the purposes of categorising Mineral Resources. The first search volume demarcated a potential Measured Mineral Resource model. A search volume of 1.5 demarcated a potential Indicated Mineral Resource model and search volume greater than 1.5 demarcated potential Inferred Mineral Resources. The search volumes are based on the relevant Au (g/t) variogram model for the relevant mineralised zone or corresponding "waste" zone. The number of samples for each search volume was determined through kriging neighbourhood studies. Final classification of Mineral Resources was based on a matrix of number of samples, search volume and kriging efficiency. The cut-off's selected to declare the Mineral Resource estimates are 0.3 g/t for the Pickstone and Peerless open pitable Mineral Resources (to a depth of 250 m) and 1.5 g/t for underground Mineral resources at both the Pickstone and Peerless prospects. The cut-off's are based on a combination of economic and technical assumptions from AFCR and values that are well within accepted industry norms for narrow tabular strata-bound or shear hosted gold deposits. Tonnage has been estimated on a dry basis and been adjusted for mining voiding and geological losses. Relative density calculated from drilling and dump sampling tests has been applied in the calculation of tonnage. The Mineral Resource estimates reported in this section are based on validated data sets supplied by AFCR. The Competent Persons have verified the final composite data accepted for the estimate. All of the geological data used in the estimation process including data which determines the extent, continuity and disturbance of the mineralised horizons has been collected and collated by qualified and suitably experienced geologists, surveyors and other mineral resource practitioners employed currently and historically at the Pickstone-Peerless Project.
ExplorMine Consultants is of the opinion that the Pickstone-Peerless Project are a Mineral Resource estimate meets the requirement of "reasonable prospects for eventual economic extraction" and in ExplorMine Consultants opinion is representative of the gold mineralisation.
1.5 Conclusions and Recommendations
This CPR is intended to fulfil two basic objectives:
To compile a JORC compliant Mineral Resource estimate for the Pickstone-Peerless Project area.
To guide management in the identification of potential mining and exploration target areas by providing an estimated three dimensional spatial expression to the estimated mineral resource.
This CPR and the technical work on which it is based provide a compliant Mineral Resource estimate. An estimated three-dimensional block model has been constructed and can be used as a tool to guide future exploration and mine planning and decision making. The status of Pickstone-Peerless Project is currently an advanced exploration property and AFCR completed a Mineral Reserve estimate in December 2013 based on the ExplorMine 30 June 2013 Mineral Resource estimate. ExplorMine Consultants and AFCR geologists collectively have extensive experience in the geology of the Pickstone-Peerless Project area and Greenstone gold style of mineralisation and the estimation thereof. The estimation was based on all available exploration and mining data. A combination of recent and historic desurveyed surface drillhole intercepts, historic underground drilling and channel sampling, digitised mine development and stoping, geological mapping, trenching and detailed topography, were used in a complete first principles structural interpretation. The Mineral Resource estimate presented in this Report for the various mineralised zones for the Pickstone and Peerless trends is based on the first principles structural model and surface drillholes, underground drilling and sampling represented by electronic databases. The data was collected over a period of an extended period of time from the 1960's to present. ExplorMine Consultants has performed its own assessment and validations on primary data, and considers the validity and quality of the data to be reasonable. The data complies with acceptable standards and norms and is considered of sufficient quality for use in Mineral Resource estimates. ExplorMine Consultants has in preparation of this Report on the Mineral Resource estimate collated and compiled a single comprehensive composite database comprising all relevant data. Composite data has not been corrected for dip and therefore represents true intercept lengths. Geological modelling recognises distinct geological zones in the both the Pickstone and Peerless mineralised trends. These zones have been used as a basis for geostatistical modelling. A block modelling process was undertaken to allow estimation of the reefs and intervening stratigraphic units in CAE StudioTM. The resultant block models are designed to facilitate the use of mineral optimisation software for further Feasibility Studies. Kriging was carried out into a geological block model, which produced a spatial distribution of low and high grade in three-dimensional mineralised structural envelopes, which enables the design of open cast or underground mining. Ordinary kriging was applied to Measured, Indicated and Inferred Mineral Resource categories.
1.6 Recommendations
As a result of the block modelling and resultant Mineral Resource estimate, additional exploration targets have been recognised for both the Pickstone and Peerless trends. In terms of the Peerless mineralised trend significant potential to upgrade the Mineral resource exists at depths greater than 100 m.
The Pickstone mineralised trend has significant potential Resources greater than Level 4 below surface, in the immediately adjacent hangingwall and footwall (widths of 15 m or more) of the higher grade mineralised zone already extensively mined. Although it is known that this halo of mineralisation exists, there is little data currently defining the grade and extent (volume) of this mineralisation. The current estimate for the underground Pickstone Mineral Resource mainly defines a central core of mineralisation. ExplorMine are of the opinion that the results of the Mineral Resource estimate presented in this Report are suitable for inclusion in a Feasibility Study for the Pickstone-Peerless Project area. AFCR have plans to continue exploration on the property once funding or revenue from mining operations. Effort is being currently directed at completing Feasibility Studies on the Project.
