QUARTERLY ACTIVITIES REPORT & APPENDIX 5B
3 MONTHS TO 31 DECEMBER 2013
Activities for the quarter ending 31 December 2013 largely focused on advancing the Mollacas Copper Leach Project, and preparatory work for the planned Pre-Feasibility Study at Los Calatos.
Mollacas Project - Chile
Results from the column leach testwork recently completed by SGS (Chile), and supervised by an independent expert, concluded the following:
-
A recovery rate of approximately 85% of the average “sequential” assayed copper grade for the deposit should be attained;
-
The recovery rate for the supergene ore could be as high as 90%;
-
Low acid consumption in the range of 12 kg/t to 14 kg/t of ore leached was achieved, a significant reduction on the previous testwork. Additional testwork is planned to ascertain whether this acid consumption rate can be reduced further by limiting the acid dosage in agglomeration.
These results will have a significant, positive, impact on the economics of the project.
The results from this testwork will form the basis for the detailed mine and processing design which is required to complete a Feasibility Study and the Environmental Impact Study (EIS), both of which are expected to be completed during the 4[th] quarter of 2014.
The Company expects a final determination on the issue of its 1[st] Extension “Servidumbre” (Right to Access) for the Mollacas Project during the 1[st] quarter of 2014.
Los Calatos Project – Peru
On 12 August 2013, the Company announced the results of further optimisation work undertaken by RungePincockMinarco at its 100% owned Los Calatos Project, the key results of which are summarised as follows:
-
Life of Mine of 34-years;
-
Comprises an open pit and underground block cave operation;
-
Total tonnes treated over Life of Mine of 811Mt at 0.47% copper and 0.03% molybdenum;
-
Annual copper in concentrate production of 98.4kt; and,
-
Cash operating costs of US$1.12/lb Cu inclusive of by-product credits.
Discussions with a number of interested parties on the future funding of Los Calatos are advancing, certain of which are to be held in Peru during February 2014.
Corporate
- Cash position as at 31 December 2013 was approximately A$7.8 million (US$6.9 million);
Mr William Howe, Managing Director commented: “The December quarter saw the successful completion of the metallurgical testwork at Mollacas, a major milestone in progressing the project towards production. The results from the column leach testwork have confirmed 85% copper recoveries with low acid consumption rates, which significantly enhance the economics of the project. Additional metallurgical testwork is to commence shortly to determine the potential to further reduce these low acid consumption rates.
The Company is well advanced with the planning for the completion of a Feasibility Study and Environmental Impact Study, which is required for mining approval at Mollacas, and expects to complete these studies by late 2014.”

KEY RESULTS
Mollacas Copper Leach Project
Testwork Results
The Phase 3 metallurgical testwork undertaken by SGS in Santiago (Chile), and supervised by an independent expert, was designed to evaluate the Mollacas copper leach process at a Feasibility Study level and to provide the information required for the completion of the design phase of the project, as well as the operating information for the submission of the requisite Environmental Impact Assessment.
The mineralisation tested consisted of oxide ore (mostly malachite with traces of chrysocolla and brochantite) and supergene ore (mainly chalcocite and covellite, with minor chalcopyrite and significant pyrite).
The proposed Mollacas copper recovery process will consist of primary, secondary and possibly tertiary crushing (dependent on final recommendations regarding optimum crush size), agglomeration, heap leaching (LX), solvent extraction (SX) and electrowinning (EW) aimed at producing LME Grade “A” copper cathode as an end-product (Appendix 1).
The results from the recently completed column leach testwork concluded the following:
-
A recovery rate of approximately 85% of the average “sequential” assayed copper grade for the deposit is attainable. The recovery rate for the supergene ore could be as high as 90%;
-
Acid consumption is expected to be in the range of 12 kg/t to 14 kg/t ore leached based on this testwork. Further testwork will be conducted concurrent with the completion of an EIS and Feasibility Study to determine whether this acid consumption rate can be reduced further by limiting the acid dosage in the agglomeration stage.
The primary leach design parameters resulting from the metallurgical testwork are:
-
Crush size: P80 12 mm to 16 mm;
-
Agglomeration acid addition: 10 kg/t (may be reduced after further testing);
-
Stacked ore depth: 6 metres;
-
Stacked dry-bulk density (maximum): 1.7 t/m[3]
-
Two-stage leach
-
150-day Primary Leach Stage: 5 L/hm[2] @ 6 g/L H2SO4 ; followed by a
-
� 150-day Secondary Leach Stage: 2.5 L/hm[2] @ 3 g/L H2SO4.
The staged leach and acid concentration values can be met with a series/parallel solvent extraction configuration, where the Primary Leach PLS feeds the two in-series solvent extraction stages, and the Secondary Leach PLS feeds the parallel extraction stage.
Assessment of operating and capital costs
Operating and capital costs for the planned Mollacas copper leach project are being re-evaluated based on the latest information available. To this extent mining contractors and equipment suppliers have been approached in Chile to provide preliminary cost estimates for a mining operation with a planned maximum production rate of 8,000 tpa of cathode copper over 8-year life of mine.
These costs, in conjunction with the results of the current column leach testwork, will form the basis of a revised life of mine financial model.
Future Work
The Company is completing all necessary environmental monitoring requirements with the assistance of a number of consulting firms with the objective of submitting an EIS to the relevant government authorities by late 2014.

LOS CALATOS PROJECT
Introduction
In March 2013 Metminco announced the results of an independent Scoping Study conducted by NCL Ingeniería y Construcción Ltda (“NCL”) on the Los Calatos Project, located in southern Peru (Appendix 2).
The mining scenario evaluated as part of the Scoping Study provided for an open pit with a life of 7-years, and a subsequent underground block cave operation with a life of 24-years, at an average life of mine production rate of 60ktpd (Appendix 3).
Since the completion of the Scoping Study, additional optimisation work has been completed by RungePincockMinarco (“RPM”), who focussed primarily on evaluating the opportunity to increase production rates for both the open pit and underground block cave operations. RPM confirmed that production rates of 75ktpd and 70ktpd are achievable for the open pit and underground block cave operations respectively (“Optimised L3_Model”) (Appendix 4). Furthermore, RPM adjusted operating and capital cost estimates to accommodate the increased production rates and resultant ‘ore’ flow.
Optimised L3_Model – Life of Mine
The key operating parameters for the Optimised L3_Model are summarised in Table 1 below, and the development and production schedule is graphically depicted in Appendix 4.
Table 1: Life of Mine – Key operating parameters Optimised L3_Model.
| Parameter | Optimised L3_Model |
|---|---|
| Total tonnes milled (millions) | 811 |
| Average annual tonnes milled (millions) | 23.9 |
| Average annual copper in concentrate (kt) | 98.4 |
| Average annual payable molybdenum (kt) | 4.8 |
| Strip Ratio (open pit) | 3.36:1 |
| Mining costs (US$/t) | 7.72 |
| Processing costs (US$/t) | 4.58 |
| G & A costs (US$/t) | 0.51 |
| By - product credit (US$/lb payable Cu) | 0.73 |
| Cash operating costs_net of credits (_US$/lb copper) | 1.12 |
| Pre-production capital (US$ millions) | 1,243 |
Note:
-
i) Cash operating costs exclude government royalties, but include all other costs and royalties. ii) By-product credits based on commodity prices Cu = US$2.95/lb, Mo = US$12.78/lb, Au = US$1,348/oz, Ag = US$25.00/oz and Re = US$5,773/kg.
-
iii) Open pit grade revised from 0.39% Cu and 0.026% Mo to 0.37% Cu and 0.023% Mo following subsequent refinement of ore flow model. This impacted marginally on metal content and hence cash operating costs.
The envisaged development schedule for the Optimised L3_Model can be summarised as follows:
Page | 3
ASX ANNOUNCEMENT
METMINCO LIMITED
31 January 2014
The project development schedule allows for construction of the surface infrastructure and the metallurgical plant to be undertaken simultaneously with the development of the open pit operation.
The life of the open pit is estimated to be 14-years. During this period a stockpile will be established to supplement production from the underground operation during the underground ramp-up stage (Years 11 to 19).
The annual contained copper and molybdenum metal in concentrate is expected to average 98.4kt and 4.8kt respectively over the life of mine.
Cash operating costs, net of by-product credits, are expected to average US$1.12/lb of copper over the life of mine, and compare favourably with global cash costs, ranking the project in the lowest quartile of global producers.
The initial capital requirement for the establishment of the open pit, surface infrastructure and metallurgical plant is estimated at US$1,320 million, which includes a contingency of 25% by virtue of the current developmental status of the project. Sustaining capital will be funded from cashflow while the development of the underground mining operation may well be financed through a combination of debt and equity to maximise project returns and free up cashflow from the operation.
The underground mine infrastructure will consist of a twin decline system, one for personnel and equipment, and an adjacent conveyor system for ore extraction. Four vertical raise-bored ventilation shafts will support the underground operation. Ore will be crushed through a primary crusher to be located underground.
Current Activities
A second, more detailed, metallurgical testwork program (conducted at a Pre-Feasibility Study level) has been planned, which will include 9 geo-metallurgical samples that represent the main ore-types which are to be mined during the open pit phase at Los Calatos, as well as Level 2005 of the underground block cave operation.
The geo-metallurgical composites have been selected on the basis of those criteria that may impact on the copper extraction process such as low grade and high grade copper equivalent zones, supergene and primary material, lithology, alteration type, and the possible presence of deleterious elements.
Future Work
The Company continues with detailed investigations that are a pre-requisite for the commencement of a PreFeasibility Study. To this end, the following work has been completed continues.
-
Design of an in-fill drilling program for the identified supergene zone, geotechnical work, as well as the sterilisation drilling required for the establishment of the requisite mine infrastructure;
-
Geotechnical studies in support of the optimised pit and underground block cave operation;
-
Phase 2 detailed metallurgical testwork;
-
Identifying the optimal location for the planned tailings dam;
-
Positioning of an infrastructure corridor to the coast; and
-
Oceanographic studies for the positioning of loading facilities at the coast.

Company Background
Metminco is a dual ASX and AIM listed company with a portfolio of copper, molybdenum and gold projects in Peru and Chile.
Premier project - Los Calatos copper-molybdenum project
Two studies have recently been completed at Los Calatos by external consultants, namely NCL (March 2013), and RPM (August 2013), which have confirmed the potential of the project as a long-life, low cost, copper producer. Both studies have focussed on the preferred mining scenario, which incorporates the estimated mineral resources for Targets 1 and 2 at Los Calatos.
The prospectivity of the broader tenement holding position remains largely untested, and as such has the potential to contribute additional material to any future mining operation developed in context of the preferred mining scenario. That is, the Company has only drill tested two of the eight targets identified to-date over a total project area of 224 km², where the latter is located in a recognised mining district characterised by the development of structurally controlled porphyry clusters.
Peru is proving to be an investment friendly jurisdiction, in which the Government is actively encouraging responsible mine development with a projected, significant, increase in long term copper production supported by competitive power costs. Mining investment in Peru over the period 2012 to 2020 is estimated to be US$53 billion, of which 70% relates to new copper mines, and extensions to existing mines. Los Calatos remains highly deliverable, being located on State-owned land in a desert environment without competing land usage, its status as Project of National Interest, and its proximity to existing infrastructure and the coast. Metminco’s strategy to access seawater for metallurgical processing purposes has been widely accepted by both local and regional authorities.
From a commodity perspective, the long-term fundamentals of the copper market remain sound, and it is anticipated that global copper production will struggle to keep pace with demand growth. With the support of a funding partner, Los Calatos has the ability to deliver copper into the global market at a time when incremental supply-demand dynamics will be dictated by production emanating from new ‘possible’ projects, the success of which will be heavily influenced by factors such as socio-political issues, restrictive legislation and technical issues (e.g. unit operating costs). Against the global backdrop of diminishing long life copper projects in mining friendly jurisdictions, and with the benefit of low unit operating costs, Los Calatos is well placed to command significant strategic interest.
Projects and mineral resources
The Los Calatos Project, located in southern Peru, has an open pittable Mineral Resource of 304 million tonnes at 0.36% Cu and 0.018% Mo (at cut-off grade of 0.15% CuEq) to a vertical depth of 500 metres below surface and an underground bulk mining Mineral Resource of 1,058 million tonnes at 0.51% Cu and 0.024% Mo (at a cut-off grade of 0.35% CuEq) commencing at an elevation of 2,500 metres (approximately 500 metres below surface).
The Chilean assets include the Mollacas Project with a Mineral Resource of 34.3 million tonnes consisting of a Measured Resource of 19.4 million tonnes at 0.45% Cu and 0.16g/t Au, an Indicated Resource of 9.4 million tonnes at 0.34% Cu and 0.16g/t Au, and an Inferred Resource of 5.5 million tonnes at 0.26% Cu and 0.15g/t Au (at a 0.2% copper cut-off); and the Vallecillo Project with a Mineral Resource of 8.9 million tonnes consisting of a Measured Resource of 5.5 million tonnes at 0.84g/t Au, 9.99g/t Ag, 1.12% Zn and 0.32% Pb, an Indicated Resource of 2.6 million tonnes at 0.80g/t Au, 10.23g/t Ag, 0.94% Zn and 0.35% Pb and an Inferred Resource of 0.8 million tonnes at 0.50g/t Au, 8.62g/t Ag, 0.48% Zn and 0.17% Pb (at a cut-off grade of 0.2g/t Au).
The Company also has a number of early stage exploration projects where initial exploration activities have identified anomalous copper, molybdenum and gold values.

Open Pit
A mine that is entirely on surface. Also referred to as open-cut or open-cast mine.
Ore
Rock containing mineral(s) or metals that can be economically extracted to produce a profit.
Ordinary Kriging
A geostatistical approach to estimating grades. Instead of weighting nearby data points by some power of their inverted distance, ordinary kriging relies on the spatial correlation structure of the data to determine the weighting values. This is a more rigorous approach to modelling, as correlation between data points determines the estimated value at an unsampled point.

Pit optimisation study
Pit optimisation studies are used for open pit mine planning to determine those pit limits and mining sequences that yield maximum financial returns based on defined technical parameters, operating costs and commodity prices.
Porphyry
A rock consisting of larger crystals embedded in a more compact finer grained groundmass.
Porphyry copper deposit
A copper deposit which is associated with porphyritic intrusive rocks and the fluids that accompany them during the transition and cooling from magma to rock. Porphyry copper deposits are typically mined by open-pit methods.
PPM
Parts per million, also grams/tonne.
PLS
Pregnant Leach Solution is the acidic metal-laden water generated from heap leaching. Pregnant Leach Solution is used in the SX/EW process.
Pre-feasibility study
A preliminary assessment of the technical and economic viability of a proposed project. Alternative approaches to various elements of the project are compared, and the most suitable alternative for each element is recommended for further analysis. Costs of development and operations are estimated. Anticipated benefits are assessed such that some preliminary economic criteria for evaluation can be calculated. Preliminary feasibility studies are completed by a small group of multi-disciplined technical individuals and have an accuracy within 20 to 30%.
