Environmental and Permitting Process
A complete environmental baseline study will be finalized by fall 2013; Environmental and Social Impact Assessment is subjected to the Canadian Environmental Assessment Agency, which will be available Q1 2014. The project notice to begin the Federal environmental permitting process was submitted before the end of Q1 2013 and the official application for the Certificate of Authorization to the Provincial "Ministère du Développement durable, de l'Environnement, de la Faune et des Parcs" (MDDEFP) is planned to be submitted by winter 2014.
Social Acceptability
Since 2009, Matamec has been committed to engaging the Temiscamingue communities to include and take into consideration their concerns in the development of the Project.
Mineral Resource Estimates
Total measured and indicated resource now stands at 23.857 million tonnes at 0.407% Total Rare Earth Oxide (TREO) representing 88% of total resource.
Mineral Reserve
Mine - total projected ore tonnage is 19.8 million tonnes with a TREO diluted grade of 0.4105%.
Projected to produce an avg. 1.33 million tonnes of ore per year (3,650 tonnes per day) and avg. stripping ratio of 0.94 with 15.2 years mine life (excluding pre-production period).
Metallurgical Plant Site
The final products of the process plant will be a chloride concentrate of HREE and a concentrate of LREO. FS results show a lower recovery compared to the PEA study, but it also shows that the process is working for the entire ore body, and highlights where the process has to be optimized in order to improve the recovery. From the previous results, a new Master Composite of ore is ready for further piloting planned for fall 2013 to improve the process.

Mr. Gauthier commented, "The Company will work with government authorities to ensure that all required areas are covered to receive environmental permits. We have assembled a highly qualified team who are focused on identifying every risk possible to ensure the environment is given the utmost respect and protected for future generations. The Company will continue its outreach efforts with the community which we have been developing over the past four years to create greater comprehension and visibility for the project. We welcome and value the concerns of the citizens of the Temiscamingue region and look forward to working together in building a sustainable plan."

Additional Upside Opportunities for the Kipawa Mine Project

Matamec has identified a number of opportunities that have the potential to add additional value to the project.

  1. The second metallurgical pilot plant testwork should be conducted in addition to the bench scale and first pilot plant testwork conducted up to now. This second pilot plant testwork will be important to confirm, prior to detailed engineering, final sizing of some process equipment. For the time being overcapacities have been built into the design, but it could be reduced during the detailed engineering, pending the pilot plant results. The second pilot plant will also help to confirm improvements in regards of recovery rates since conservative numbers were used for the FS.
  2. It would be significant to consider some testworks to separate individual Rare Earths (RE) to increase the value of the project.
  3. Depending on the RE market conditions, it will be important to continue the evaluation of other LREE concentrates and HREE concentrates production scenarios in order to optimize the IRR before detailed engineering.
  4. In the future and when the project is well in progress, testwork can be performed to evaluate the possibility to recovering zirconium and other minor metal by-products in the RE mineralized zones and in the syenite body.
  5. Mineral resources on the Kipawa deposit can be increased by verification of lateral and down dip extensions by drilling.
  6. From the last results in the FS it is known that there is the potential room for improvement in the open pit design when entering the detailed engineering phase.

Considering the above mentioned points, the Company strongly believes it can achieve greater success with bringing the IRR above 25% by only slightly reducing the CAPEX and OPEX while improving the recovery.

Review of the FS Project Development Model

The FS covers all aspects of project development, including mining, mineral concentration, hydrometallurgical processing and separation of heavy and light rare earth as well as all related infrastructure. Roche developed its capital and operating cost estimates from first principle capital quotations, estimates from suppliers, manufacturers, contractors and experience based on comparable operations in Canada and abroad. The capital and operating cost estimates were completed to a level consistent with an intended level of accuracy of ± 15%.

Project Location

The Kipawa deposit is located on the Zeus Property (see map below), 50 km east of the town of Temiscaming and 140 km south of Rouyn-Noranda, Quebec. All claims are in good standing. Resources are not subject to any third party royalties.

To view the map of the Kipawa deposit, kindly click on the following link:

General Project Infrastructure Description

About 50 km of the Maniwaki road will be used to access the Kipawa Project and share with public and other logging companies. Then a 4 km road will be built from the Maniwaki road to reach the process plant site.

The Kipawa mining site will consist of the open pit mine, a waste dump, a low grade stockpile and a high grade truck loading facility. The mine equipment maintenance facility will also be located at the mine site.

The metallurgical process plant site will be located south of the mine site and south of the Kipawa River and a 10 km haul road will be built to link the two sites. The metallurgical site will consist of the ore process plant which will combine the crushing, grinding, magnetic separation and hydrometallurgical circuits. At this site, there will also be the administration and service building, a warehouse and the assay laboratory.

There will be two dewatered tailing storage facilities; one storage facility will be for the rejects of the magnetic separation process located just by the process plant and one other storage facility for the hydrometallurgical tailing located about 4 km south of the process plant.

The employee's parking and the main electrical sub-station will be located near the town of Temiscaming. In the present study it is planned to build a 44kV power line along the Maniwaki logging road to provide power to the mining and processing facilities.

Geology, Mineralogy and Mineralization

The ore deposit is defined by three enriched horizons within the "Syenite Complex", which contains the fifteen rare earths elements present. The Kipawa Alkaline Intrusive Complex consists of peralkaline syenite and granite on average is less than 200 metres thick. It's an elongated, V-shaped body folded around a major southeast plunging anticline. The west limb of this fold includes the Kipawa deposit, which is entirely included within the lower syenite layer of the complex. This mineralized syenite layer is a concordant sheet 50 to 80 meters thick that gently dips 20 to 30 degrees to the south-west. The deposit outcrops over 1.4 km along strike with an additional outcrop discovered 220 m to the north-west during the summer 2011 exploration campaign.

Rare earth-yttrium-zirconium mineralization at the Kipawa deposit is contained in medium grained silicate minerals. Grains are distinct and generally well crystallized. Three minerals are presently considered economical in the Kipawa deposit, namely eudialyte (a sodic silicate), yttro-titanite/mosandrite (titanite silicate) and britholite (calsic silico-phosphate) for the rare-earth and yttrium, with minor amounts of apatite also present. Vlasovite/gittensite (sodic silicates) and eudialyte (sodic silicate) are also considered for a potential zirconium by-product.

Three vertically-stacked mineralized zones have been defined based on their spatial characteristics: the Eudialyte (60% of existing rare earth-yttrium resources), Mosandrite (25% of existing rare earth-yttrium resources) and Britholite (15% of existing rare earth-yttrium resources) zones. Despite their name, the different zones contain a mix of the potentially economic minerals. The name simply indicates the dominant REE mineral present in that zone. The main Eudialyte zone, for example, consists of intermixed eudialyte (51%) and mosandrite/yttro-titanite (39%) with trace britholite (10%). It sits near the top of the syenite body and is not associated with any large calco-silicate horizon. Note that all zones outcrop at surface.

The Kipawa deposit contains very low-levels of uranium and thorium in the main REE-Zr mineralization. Average values of Th (193 ppm, or 0.019%) and especially U (22 ppm, or 0.002%): though higher than in the surrounding rocks remains very low in the mineralized syenite portion of the Kipawa deposit. Initial results suggest that most of the thorium is contained in coarse-grained urano-thorite and ekanite crystals, while the uranium is disseminated within said urano-thorite and rare-earth minerals.

The terms "Mineral Resource" and "Mineral Reserve" are defined in the CIM Definition Standards - For Mineral Resources and Mineral Reserves adopted by the CIM council of the Canadian Institute of Mining, Metallurgy and Petroleum.

Mineral Resources

The Kipawa Deposit resource are 10,478,000 tonnes at 0.46% TREO in the measured category, 13,379,000 tonnes at 0.36% TREO in the indicated category and 3,268,000 tonnes at 0.31% TREO in the inferred category. The total of measured and indicated resource now stands at 23,857,000 tonnes at 0.41% TREO representing 88% of the total resource. These results are at a 0.2% TREO cut-off and are not limited by an open pit. The overall total tonnage is about 10% greater than the last resource calculation (see press releases dated June 30 and July 7, 2011).

The Kipawa deposit's mineral resource estimates were updated by SGS Geostat. The drilling done since the 2011 PEA (see press release dated January 30, 2011) totaling 14,293 m was included and permitted to outline some measured resources for the first time in the history of the project. The database now totals 293 drill holes totaling 24,571 m and 13 trenches totalling 631 m. Historical Unocal holes are not in the count and were not used for the estimates. The mineralized zones were interpreted on vertical sections and meshed into volumes as per industry standards. Ordinary Kriging was used to estimate the block model with block size set at 10 m x 5 m x 5 m. The measured and indicated resources required drill grids of 25 m and 50 m, respectively. Resources extrapolated beyond 30 m of those drill grids are considered inferred.

Mineral Reserves

By using SGS Geostat model, the mineral reserve for this FS was prepared, estimated and supervised by Roche using a cut-off value of $48.96/t with 5% dilution and a mining recovery of 95.2%. The Kipawa open-pit design utilized a marginal (or milling) cut-off value of $48.96/t and a break even cut-off value of $60.70/t. Included in the reserves are 632,000 tonnes of low grade material lying between these 2 cut-offs values. This material will be sent to a low grade stockpile, close to the mine site and will be processed at the end of operation after mine depletion.

Design Basis

The Total Rare Earth Oxides (TREO) diluted grade is 0.4105% including a dysprosium (Dy2O3) diluted grade of 0.0147%. The calculation is using a dilution grade of 0.093% TREO. The recoveries for each element vary from 65% to 74% for a TREO average of 70% for the 10 main REO which are (La2O3, Ce2O3, Pr6O11, Nd2O3, Sm2O3, Eu2O3, Gd2O3, Tb4O7, Dy2O3 and Y2O3). A total production of TREO is expected to be 55,529 tonnes over the mine life. When the mine will be in full production (year 2-15) an average of 3,760 tonnes per year of TREO will be produced.


The mine will produce an average of 1,332,250 tonnes of ore per year (3,650 tonnes per day) and has an average stripping ratio (waste : ore - without the overburden) of 0.94 with a mine life of 15.2 years. A standard 55 tonne mining truck and shovel operation will bring the drilled and blasted material out of the mine to their respective destinations (waste dump, low grade stockpile or high grade loading facility). Then the ore is transported by 40 tonne HD dump trucks to the metallurgical plant site.


Once at the metallurgical plant site, the ore will be dumped into a crusher dump hopper feeding a two stage crushing circuit. The crushed ore will then be stored into a silo. The crushed ore will feed the process plant at the rate of 3,650 tpd in a single stage grinding circuit. A magnetic separation circuit will recover the rare earth as a first concentrate. The reject from the mag-sep circuit will be pumped to the dewatering circuit and transported by truck to the mag-sep rejects storage facility located outside and nearby the process plant. The magnetic rare earth concentrate will be sent into the regrind mill followed by a thickening circuit and then to the hydrometallurgical process (acid leaching, neutralization, impurities removal and the final precipitation) will then produce the rare earth carbonate concentrates. This hydromet concentrate will then be processed through a purification circuit which will remove the last impurities and also separate the heavies from the lights. The final products of the process plant are a concentrate of heavy rare earth and a concentrate of light rare earth.

The tailings produced from the hydrometallurgical process will be pumped to a thickening facility located by the hydromet tailings storage facility (TSF). The solids will be dewatered in few steps using different technologies and then transported by truck and disposed mechanically into the TSF. This TSF is thus believed to be subject to progressive restoration throughout the mine life. Then the final section is to be restored at the end of the mine life as well as the other sites with varying infrastructures. The hydromet tailing storage facility will require further investigation and design work as the project advances into the next stages.

A total of 10 MW will be needed to power both the mine site and the metallurgical site and will be provided by a new power line to be connected to the Hydro-Quebec network.

In 2010, testwork at SGS Canada Inc. in Lakefield (Ontario) was directed toward examining a known recovery process employing aggressive conditions for extraction of rare earth elements (acid baked leaching). By early 2011, it had become evident that much less aggressive conditions than anticipated were possible for the extraction of the particular minerals present in the Kipawa ore (room temperature leaching); this allowed a substantial improvement in simplifying the projected process plant design.

The present study is based on metallurgical test work results dating prior to June 1, 2013. A pilot plant was performed during the summer of 2012 with a Composite of ore taken from a bulk sample coming from surface trenches. Then a series of variability samples were taken from trenches and core samples from 18 large caliber drill holes in order to make eight (8) Composites and also a Global Composite in order to verify if the process was valid for the entire ore deposit. Results showed lower recovery compared to the PEA study but it also showed that the process works for the entire ore body and also where the process needs to be optimized in order to improve the recovery.

From these previous results, a new Master Composite representing the ore body is ready for further piloting which is planned for the fall of 2013, to further improve the ore processing plant.

Market Study

The Rare Earth Elements (REEs) are typically defined as the fifteen lanthanide elements including yttrium and scandium; they form a group of technology enabling materials that are critical inputs for a wide range of everyday consumer products as well as a large number of cutting edge technologies. Strong magnetic, optical, electronic and catalytic properties have made certain rare earth compounds indispensable to a substantial portion of global industry, including but not limited to the automotive, consumer electronics, medical equipment and green technology sectors.

The demand for heavy rare earth materials is expected to benefit from strong growth, particularly in the case of dysprosium, terbium and yttrium, which are likely to realize swiftly expanding consumption from both the permanent magnet and phosphor powder sectors. The permanent magnet sector (neodymium and dysprosium and to a lesser degree terbium) is generally forecasted to realize strong gains in annual consumption through the entirety of the next seven years. The combination of tightening Chinese supply along with growing demand suggests terbium, dysprosium and several other HREEs will see appreciating price levels. Though demand for yttrium is expected to expand.

The Rare Earth Oxide prices used for the economic evaluation are based on a contracted market survey by Asian Metals (one of world's largest metallurgical information providers) in conjunction with discussions with key industrial end-users which were important in defining the forecasted final prices of each rare earth oxide. Other sources consulted for review of the historical pricing data were websites and reports from Metal Pages, Roskill Information Service Limited and Industrial Minerals.

Furthermore, the refining cost to reach 99.9% oxides or even higher purity levels was not evaluated within the FS since refining was not considered in the scope of the FS. It was decided that since the forecasted prices are for 99.9% (min.) pure, individual oxides and Matamec will be producing two mixed Rare Earths concentrates; a mixed light rare earth concentrate that will contain the following REE's: Ce, La, Nd and Pr. With the second product, a mixed heavy rare earth concentrate that will contain the elements of: Sm, Eu, Gd, Er, Tb, Dy, Ho, Yb, Tm, Lu and Y. The projected selling prices for the concentrates will be based on their contained oxide pricing and will be reduced by a refining factor of 30% for the majority of the Rare Earths, but 40% for the REE's: Ho, Er, Yb, Tm and Lu. The higher discount was applied considering that these materials would require more costs associated to process them due to the higher degree of purity that is required by their associated end uses. It is considered that the respective discounts will cover all logistical costs for the material to be shipped to their intended point of separation.

The Project is subject to a joint venture agreement (the "JVA") between Matamec and Toyotsu Rare Earth Canada Inc. ("TRECan"), a subsidiary of TTC (see press release dated July 12, 2012 for more details on the JV and the JVA). As at the date hereof, Matamec holds a 51% and TRECan a 49% interest in the Project (see press release dated August 8, 2013). The JVA contains a provision under which TTC shall become the off taker of the production from the Project, under the terms and conditions set out in the JVA and in the off-take agreement to be negotiated and executed by the parties. Negotiations to convert the agreement into contractual volumes will follow the completion of the FS. TRECan is a well-recognized strategic partner that has funded $16.0 million to Matamec to complete the FS.

Economic Analysis

An economic/financial analysis of the project has been carried out using a cash flow model. The model is constructed using annual cash flow in constant money terms (second quarter 2013). No provision is made for the effects of inflation. As required in the financial assessment of investment projects, the evaluation is carried out on a so called "100% equity" basis, i.e. the debt and equity sources of capital funds are ignored.

Item Base Case Value Unit
Total Ore Mined 19.77 M tonnes
Processing Rate 1.332 M tonnes / year
Life of Mine 15.2 years
Average Combined Process Recovery 70 %
Average Mining Cost 7.03 ($ / tonne mined)
Average Processing Cost 36.57 ($ / tonne milled)
Average General & Administration Costs 8.71 ($ / tonne milled)

Financial Model and Results

A capital cost breakdown by item provides a preliminary capital spending schedule over a 2-year pre-production period. The total pre-production capital expenditures are evaluated at $374.4 million, excluding the working capital. The total sustaining capital requirement is evaluated at $37.7 million which includes rehabilitation expenditures. A working capital equivalent of 3 months of total annual operating costs is maintained throughout the production period. Apart from the first fills and spare parts included in the pre-production capital expenditures, an additional working capital outlay of $11.2 million is required. The total operating costs are estimated at $1.181 billion for the life of the mine or an average of $58.9/tonne milled. The financial results indicate a positive before-tax NPV of $260 million at a discount rate of 10%, a before-tax IRR of 21.6% and a payback period of 3.88 years.

Sensitivity Analysis

A sensitivity analysis has been carried out on the base case scenario described above to assess the impact of changes in REE market prices, total pre-production capital costs and operating costs on the project's NPV @ 10% and IRR. Each variable was examined independently. An interval of ±30% with increments of 10% were used for all three variables. The project's before-tax viability is not significantly vulnerable to the under-estimation of capital and operating costs, taken independently. The net present value is more sensitive to variations in operating expenses. As expected, the NPV is most sensitive to variations in REE prices, followed by operating costs and by capital costs.

Environment, Permitting and Social Acceptability

Environment and Permitting

Matamec has always been proactive and has respected the rules outlined by the different government authorities.

After the first drilling campaign outlined a good quality deposit (2009), Matamec decided to begin a baseline study of the territory around the deposit. Enviréo Conseil, an independent firm from Rouyn-Noranda, Quebec, was hired to perform the study of water, fish, aquatic plants and mud samples which were taken from 5 sites, instead of the 3 recommended by regulation.

Then in spring 2012, Matamec hired the firm Golder Associates Ltd to complete the baseline study that was started two years before and also to perform an Environmental and Social Impact Assessment which is planned to be completed by Q1 2014.

A comprehensive program of geochemical characterization has been conducted during the last year in order to classify all the varying rock types to be mined, the ore, the overburden and also all the different waste and residue to be generated by the mine and process operation. The waste rock, ore, and magsep tailings are classified as non-acid generating. The hydromet tailings sample analyzed is classified as acid generating based on its high sulfur content but all sulphur occurs as sulphate which is already oxidized and therefore not expected to generate acidity in the future.

Further radiological analyses of leachates were carried out for safety purpose and as required under Directive 019 of the MDDEFP to evaluate the level of risk associated with possible leaching of radiogenic parameters from mine wastes, magnetic separation rejects and hydrometallurgical tailings. None of the samples analysed are classified as high risk waste based on radionuclide analyses in leachate. Analyses were also done on the solids themselves and so far the hydrometallurgical tailings are classified as potentially radiogenic, but manageable. The implementation of proper management programs in regards to radioactive elements will ensure the safety of the workers and of the population during operation and after the mine closure. Furthermore, additional geochemical analysis will be conducted before detailed engineering in order to determine all the final classification and design parameters for the infrastructures related to the tailings management.

Hydrological and hydrogeological studies were carried out as well. From the collected information, a water management plan has been put together and will be optimized at further stages in the project. A site-wide water quality evaluation study is underway to determine future water treatment needs at the mine site and hydrometallurgical waste storage sites.

From all the information collected during the FS, it was decided to proceed with dewatered tailings even if it is much more expensive in operating costs in order to minimize environmental risks related to the tailings management. It will also allow the operator to consider progressive site restoration during mine operation.

The mining lease was filed before the end of March 2012. The project notice to begin the Federal environmental permitting process was submitted before the end of Q1 2013. The restoration plan and environmental impact study commenced at the beginning of May 2012 and are still ongoing but are well advanced. The official application for the Certificate of Authorization to the MDDEFP is planned to be submitted by winter 2014.

Social Acceptability

Since 2009, the Matamec Team is making social acceptability a priority for the Kipawa Project, as well, the Company is committed to being visible to the people in the region as a socially responsible neighbour.

In March 2012, our regional office was opened in downtown Temiscaming, creating visibility and allowing easy accessibility to information for people in the region. Regular meetings and discussions are held with the First Nations Communities, with the signature of a Memorandum of Agreement with them. Under this agreement, the First Nations communities completed their own cultural impact assessment study describing the past and current traditions and resources used in the project area. They also completed their socio-economic baseline report for the project. These studies will contribute to the preparation of the environmental effects assessment of the Kipawa project.

There is an open and constant communication between the Matamec team and the citizens. Public information meetings are held throughout the region, highlighting our commitment to dialogue and opportunities for questions about the project.

We strive to understand all stakeholders concerns and maintain our strategy of transparency executed through active and consistent communication.

The Mineral Resource and Mineral Reserve estimates set out in this news release were classified according to the CIM Definition Standards - For Mineral Resources and Mineral Reserves (as adopted by CIM Council in November 2010).

Readers are advised that Mineral Resources not included in Mineral Reserves do not demonstrate economic viability. Mineral Resource estimates do not account for mineability, selectivity, mining loss and dilution. These Mineral Resource estimates include Inferred Mineral Resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that Inferred Mineral Resources will be converted to Measured and Indicated categories through further drilling, or into Mineral Reserves, once economic considerations are applied.

About Matamec

Matamec Explorations Inc. is a junior mining exploration company whose main focus is in developing the Kipawa HREE deposit with TRECan.

In parallel, the Company is exploring more than 35 km of strike length in the Kipawa Alkalic Complex for rare earths-yttrium-zirconium-niobium-tantalum mineralization on its Zeus property. Since 2008, Matamec discovered many potential showings. Particularly, it drilled the PB-PS Zone in the fall of 2012 and identified similar Eudialyte-Mosandrite/Yttro-Tantanite/Britholite associated mineralization founded at the HREE Kipawa Deposit. This type of mineralization is presently known over 200 metres long and it opens laterally and at depth. The Company plans to drill these extensions later this year.

The Company is also exploring for gold, base metals and platinum group metals. Its gold portfolio includes the Matheson JV property located along strike and in close proximity to the Hoyle Pond Mine in the prolific gold mining camp of Timmins, Ontario. In Quebec, the Company is exploring for lithium and tantalum on its Tansim property and for precious and base metals on its Sakami, Valmont and Vulcain properties.
