Results of completed Definitive Feasibility Study


The Board of Xtract Resources Plc (“Xtract” or the “Company“) are pleased to announce that the Definitive Feasibility Study (“DFS”) for the open pit operation of the Company’s Manica Fair Bride Gold Project in Mozambique (“Project” or “Fair Bride“) has been completed by Minxcon (Pty) Ltd (“Minxcon“) and the results of which are summarised below. A copy of the DFS is available from the Company’s website,


 ·    After-tax Internal Rate of Return (“IRR“) of 41.1% at a gold price of US$ 1,262 per ounce

·    Project life of 7 years with average gold grade of 2.62 g/t producing 215,293 recovered ounces   

·    Project payback within 2 years

·    Direct cash cost (“C1“) of US$556 per ounce

·    All-in sustainable cost (including royalties and capital)(“AISC“) of US$862 per ounce

·    Total capital expenditure of US$43.68 million

·    The Net Present Value (“NPV“) of US$ 42 million at 8.4% discount rate

·    Significant exploration potential in immediate vicinity

·    A further 992,000 ounces in resource for additional evaluation and future exploitation

·    Considerable exploration potential within the concession and nearby


Colin Bird, Executive Chairman, said: “I am pleased to report that the DFS has produced a robust Project which is neither complex nor capital demanding. The Project has major upside potential which can be exploited later against a fully paid for processing plant. Opportunity exists for hard rock consolidation which we are exploring. The alluvial opportunity is extensive and we are currently discussing and negotiating third party mining contracts. We are already working on reducing capital numbers and introducing practical engineering to further reduce risk and enhance project financial parameters.”

 Daan van Heerden of Minxcon, said: “The Manica study has produced a robust project targeted toward simplicity and predictability. We concur with managements approach to the concession and agree that the previously announced hybrid approach might have led to enhanced capital and operating risk.”

 Further details are available from the Company’s website which details the company’s project portfolio as well as a copy of this announcement:


 Valuation Date

The effective date of the DFS financial evaluation is 1 January 2017 (“Valuation Date“) and Minxcon has stated that is not aware of any material changes that occurred between the Valuation Date and 28 February 2017, being the DFS report date (“Report Date“).

Resource Estimate

The Company published on 11 May 2016 the Minxcon independent technical report on the Fair Bride Gold Project issued 15 April 2016 (“Mineral Resource Statement“).  The DFS was based on, and the reported resources are as set out, in the Mineral Resource Statement. A geological model of the Fair Bride orebody was constructed. These sections were used to create a wireframe for the orebody or mineralised portion.

The Mineral Resource was classified into Measured, Indicated and Inferred Mineral Resource categories as defined in the SAMREC Code based on the kriging efficiency, number of samples and search radii. The Mineral Resource estimation for the Fair Bride open pit is presented in Table 1 below, declared to a depth of 280 m with a resource cut-off of 0.5 g/t. The open pit contains predominantly Measured and Indicated Mineral Resources and is SAMREC-compliant.

Project Summary

Mining Method

The mining method that will be implemented at the Manica Project is Contractor Mining with Conventional Open Pit Mining, using truck and excavator combinations.  The mining method requires the removal of topsoil which will be stockpiled. The mining of the harder material is conducted with drilling and blasting activities.


Mining Cut-off Grade

A mining cut-off grade of 0.4 g/t was applied for the open pit project and all material below 0.4 g/t is classified as waste.  The economic cut-off grade from the pit optimisation was calculated as 1.05 g/t.  All material between 0.4 g/t and 1.0 g/t is therefore classified as low grade material.  The Run of Mine (“RoM”) ore for this project is ore material with a grade in excess of 1.0 g/t. The RoM material is fed to the processing plant at 42 ktpm.


Pit Optimisation

The objective of open pit optimisation is to determine an open pit shape (shell) that provides the highest value for a deposit. The final pit design and production scheduling are based on the selected pit from the pit optimisation.


Diluted Production Schedules

The production schedule prioritises oxide material early in the Life of Mine to ensure higher initial ore recoveries. The average stripping ratio is 7.6 (strategic ore considered as waste). The production scheduling of the final pit resulted in a life of mine of 7. A smoothed plant feed of 42 ktpm was possible without the need for pre-stripping.  Oxide material will be depleted within two years and fresh material will gradually be introduced until year four, thereafter only fresh material will be processed.


Processing Strategy

The material will be crushed in a three stage crushing circuit prior to processing in a ball milling and classification circuit.


Engineering and Infrastructure

The Manica Gold Project is located 3.7 km to the north of the town of Manica. The project can be classified as a greenfield’s project with minimal to low infrastructure being available on the project area. In order to establish a fully functional gold mining operation a number of critical infrastructure items are required. These will include reliable power supply infrastructure that has sufficient capacity to serve the mining operation and process plant with the required amenities.


Capital Estimation

A contingency of 10% was added to all the capital. No additional renewals and replacements costs have been included for the mining in the model as this is accounted for in the mining contractor rate. A 6.0% renewals and replacement cost was included for the plant based on the plant operating costs.


The initial (year 0) capital costs and peak-funding requirement amounting to USD44 million. The funding requirement is for contractor mining and excludes the initial fleet cost as the fleet cost is included in the contractor rate. The engineering, procurement, and construction management (“EPCM”) cost is included in the capital costs. After the first year the only capital is for Tailings Storage Facility wall expansions.


Power supply to the project area constitutes a risk due to misalignment with the project timeline and the construction timeline of Electricidade de Mozambique (“EDM“). Xtract needs to set up a contact session with the EDM to align timelines for the required installations and upgrades to the power supply network. Capital allowances have been made for these upgrades and installations.


Macro-Economic Forecasts

Macro-economic forecasts and commodity prices in the DFS as set out below in Tables 3 and 4 were used by Minxcon in the DCF. The gold price was sourced from a number of different bank and broker forecasts by Minxcon and reviewed with the Company. The gold price was kept in constant money terms throughout life of mine (“LoM“).

To produce an ounce of gold, mining companies incur not only operating costs, but also spend sustaining capital at the sites and capital on exploration, in order to sustain their long-term future. The cost components described below are broken down into fixed and variable costs. The fixed costs are based on a fixed amount throughout the year, which is independent of production and are shown as a USD input. The variable cost is directly dependant on the Milled tonnes (USD/gold tonne milled) for the plant and the waste or ore tonnes (USD/waste tonne or USD/ore tonne) for the mining.


The operating costs in the financial model and DCF were broken down into different categories:


(C1) – Direct Cash Cost;

(C2) – Production Cost; and

(C3) – All-in Sustainable Cost (“AISC”).


Detail about the operating cost and the breakdown of the mining, loading arrangement and other costs are described in the Operating Expenditure Report. The financial cost indicators are displayed per milled tonne as well as per recovered gold ounces. The saleable gold ounces over the LoM amounts to 215,293 ounces. A 10% contingency was included on the mining and plant capital cost. Fair Bride Mine has a direct cash cost of USD37/Milled t and an all-in sustainable cost of USD58/Milled t which equates to C1 costs of USD556/oz and AISC of USD862/oz.

Summary of Discounted Analysis

The higher the IRR on a project and the greater the amount by which it exceeds the cost of capital, the higher the net cash flows to the investor. Table 5 below illustrates the value of the Fair Bride Mine based on the real time model for the orebody. The DFS has a best estimated value of USD42 million at a real discount rate of 8.40% and an IRR of 41.1%.

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 price and grade have the most significant impact on the sensitivity of the Project. The Project is not capital sensitive.

Indicated Resource








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 Resource







That part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and sampling 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 that may be limited or of uncertain quality and reliability

Measured mineral resource









That part of a mineral resource for which quantity, grade or quality, densities, shape, and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity

Mineral resource








Concentration or occurrence of diamonds, natural solid inorganic material or natural fossilized organic material including base and precious metals, coal, and industrial minerals in or on the Earth’s crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge

Mineral Reserve







A Mineral Reserve is the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at Pre-Feasibility or Feasibility level as appropriate that include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified.

Probable Mineral Reserve

A Probable Mineral Reserve is the economically mineable part of an Indicated, and in some circumstances, a Measured Mineral Resource.

Proved Mineral Reserve


A Proved Mineral Reserve is the economically mineable part of a Measured Mineral Resource. A Proved Mineral Reserve implies a high degree of confidence in the Modifying Factors.
