Focus Graphite and SOQUEM Report High Hydrometallurgical Recoveries of Rare Earth Elements from the Kwyjibo REE Project

/ -- OTTAWA, ONTARIO--(Marketwired - Nov 21, 2016) - Focus Graphite Inc. (TSX VENTURE:FMS)(OTCQX:FCSMF)(FRANKFURT:FKC) ("Focus" or the "Company") and partner SOQUEM Inc. ("SOQUEM") are pleased to announce the results from the 2014-2015 hydrometallurgical tests conducted on the Kwyjibo Poly-metallic Rare Earth Elements-Copper-Iron-Phosphate Project ("Kwyjibo" or the "Project"), located in the Côte-Nord administrative district of northeastern Québec.


  • Relatively simple metallurgical flowsheet, a distinctive feature of the Kwyjibo project among peer rare earth element projects.

  • Approximately 90% extraction rate from rare earth concentrate for all rare earth elements for the Magnetitite Mineralization Type ("MM1").

  • The plan is to perform an initial Mineral Resource Estimate, followed by a Preliminary Economic Assessment study in 2017-18.

Focus Graphite President and CEO Gary Economo said: "While the economics of the Kwyjibo Project are still to be confirmed, the initial test results support Focus' long-term investment decision to continue developing Kwyjibo's potential."

"More," he said, "we anticipate our hydrometallurgical test results may have a positive impact on our future development positioning within the framework of Quebec's Plan Nord northern development initiatives."

"These results combined with the high grade, thickness, and continuity of the mineralization within the Josette Horizon illustrates that the Kwyjibo Project has the potential to generate positive economics and indeed, interest from within this global industry. We look forward to initiating the Preliminary Economic Assessment," Mr. Economo said.

Kwyjibo Rare Earth Project Metallurgical Testwork

The latest hydrometallurgical leaching test program was conducted at Hazen Research in Colorado, USA. The program studied the use of three types of acid (H2SO4, HCl and HNO3) on various types of mineralization and subjected them to a beneficiation flowsheet that was previously developed at COREM, of Quebec City. Hazen research confirmed an average recovery of 90% of rare earth elements also obtained at COREM and Hazen also measured these high extraction rates under non-optimized leaching conditions.

The Hazen program was conducted on two (2) composite samples that are representative of the two types of mineralization that are characteristic of the northeast portion of the Josette Horizon. The first composite sample of MM1 was taken from HQ-diameter drillcore that were split in half from two drill holes (10885-13-61A and 10885-13-69A). The representative MM1 sample is a hydrothermal massive iron formation, with variable amounts of veins containing REE-bearing phosphates and silicates as well as calc-silicate minerals. The second composite sample of Breccia Type ("BR1") mineralization is composed of HQ-diameter drillcore splits from three diamond drill holes (10885-13-73A, 10885-13-74A and 10885-13-69A). The representative BR1 sample is characterized by a stockwork of magnetite veins, REE-bearing phosphates and silicates, and calc-silicate minerals in a granitic host rock. Mineralogical studies performed at COREM in 2013 show that REE occur in phosphate (apatite and britholite) and silicate (allanite and kainosite) phases.

Testwork results to date show that silicate concentrates produced from the composite samples leach well with nitric acid and hydrochloric acid. There is therefore no reason to separate the phosphates and silicates that both contain rare earth elements. Extraction using sulfuric acid gave poor results and therefore it was eliminated as a choice for acid leaching.

"From the work performed, it was determined that the differences between the REE extractions for HCl and HNO3 were minor." (1) Hazen Research, HYDROMETALLURGICAL WORK FOR KWYJIBO PROJECT, PREPARATION AND LEACHING OF RARE EARTH CONCENTRATES, project 12182, August 2016

With the current price of these two types of acids, the use of HCl appears to be a more economical choice when considering operating costs. The following graphs show that the use of a 6 Molar ("6M") concentration of HCl at 90°C, achieved approximately 90% extraction from rare earth concentrate for all rare earth elements for the MM1 Combined and the BR1 mineralization types.

When considering all the mineral beneficiation processing steps previously developed by COREM (grinding, magnetic separation, flotation), followed by the leaching extraction developed by Hazen the non-optimized global recoveries of rare earth elements are described in the following table:

REE Global Non-Optimized Recoveries: Beneficiation + HCl Extractions

Composite Sample Global Recovery (%)
Y Pr Nd Eu Tb Dy
MM1 73.9 79.4 78.6 77.4 76.7 75.7 78.8 76.4 74.9 78.5 77.6
BR1 81.1 89.8 88.0 85.6 85.6 86.5 88.8 87.0 87.1 88.5 88.3
LREE (light rare earth elements): La+Ce+Pr+Nd+Sm
HREE (heavy rare earth elements): Eu+Gd+Tb+Dy+Ho+Er+Tm+Yb+Lu
TREE (total rare earth elements): La+Ce+Pr+Nd+Sm+Eu+Gd+Tb+Dy+Ho+Er+Tm+Yb+Lu

The mineral processing flowsheet for the Kwyjibo project will therefore consist uniquely of minimal comminution steps followed by magnetic separation to remove the magnetite. Such a minimal beneficiation flowsheet will simplify operations.

On-going Laboratory Test Program:

The current hydrometallurgical test program ongoing at Hazen research is focused on the leaching of non-magnetic products and the concentration/precipitation of dissolved rare earth elements. Hazen will continue to optimize the process flowsheet by working on the liberation size and grinding, as well as magnetic separation and leaching.

Future Program:

Very encouraging results were obtained with both ore types, but since the in situ value of the MM1 mineralization type is higher, future efforts will aim to optimize the recovery of REE's from Kwjybo's MM1 mineralization type. That portion of the mineralization is located closer to surface and would potentially be less costly to mine. This combined with the fact that it is much easier to process than the BR1 mineralization type, the consensus was to proceed towards this objective.

After completion of the current testwork program, SOQUEM and Focus Graphite intend to complete an initial Mineral Resource Estimate to be followed by a Preliminary Economic Assessment in 2017-18.

Terms of the Agreement

On August 3, 2010, the Company announced the signing of an option agreement with SOQUEM Inc., to acquire a 50% interest in the Kwyjibo project. Under the terms of the agreement, Focus could acquire a 50% interest in the Kwyjibo project, by spending up to $3 million in exploration work on the project over a period of 5 years of which $1 million had to be spent during the first 2 years. SOQUEM is the operator for the exploration work carried out on the project to date and Focus has the option to become the operator, by paying $50,000 in cash or issuing a block of common shares valued at $50,000. As of the year ended September 30, 2016 Focus had spent $6.6M on the Kwyjibo project and has accordingly earned its 50% interest.

About Focus Graphite

Focus Graphite Inc. is an advanced exploration and development mining company with an objective of producing graphite concentrate at its Lac Knife deposit located south west of Fermont, Québec. In a second stage, to meet Quebec stakeholder interests of transformation within the province and to add shareholder value, Focus is evaluating the feasibility of producing value added graphite products including battery-grade spherical graphite.

The Lac Knife project hosts a Measured and Indicated Mineral Resource Estimate* of 9.58 million tonnes grading 14.77% graphitic carbon (Cg) (432,000 tonnes Measured @ 23.66% Cg and 9,144,000 tonnes Indicated @ 14.35% Cg) as natural flake graphite with an additional Inferred Mineral Resource Estimate* of 3.1 million tonnes grading 13.25% Cg. Focus' goal is to assume an industry leadership position by becoming a low-cost producer of technology-grade graphite concentrate.

The Feasibility Study filed with SEDAR ( on August 8, 2014 for the Lac Knife Project indicates the project is economically viable and has the potential to become a low cost graphite concentrate producer based on 7.86 million tonnes of Proven and Probable Mineral Reserves** grading 15.13% Cg included in the Mineral Resource (429,000 tonnes Proven @ 23.61% Cg and 7,428,000 tonnes Probable @ 14.64% Cg).

On May 27, 2014 the Company announced the potential for high value added sales in the Li-ion battery sector following battery coin cell tests performed on Spherical Graphite ("SPG") produced from the Lac Knife graphite concentrate. Testing measured the performance metrics and confirmed Focus' capability to tailor lithium ion battery-anode-grade graphite and value added products to meet the most stringent customer specifications.

On February 26, 2015, the Company announced the results from independent laboratory testing that indicated Coated Spherical Graphite ("CSPG") produced from Lac Knife concentrate outperformed synthetic graphite anodes for use in lithium-ion batteries.

On November 25, 2015, the Company announced results from independent laboratory testing that reported "zero loss" in long-term battery anode cycle testing of high purity CSPG produced from Lac Knife concentrate.

On March 31, 2016, the Company announced the introduction of a high conductivity graphite cathode material produced from expanded Lac Knife graphite and exhibiting twice the conductivity of cathodes versus standard grades of synthetic and natural flake graphite used in commercially available lithium-ion batteries.

On August 8, 2016, the Company announced it has successfully purified fine flake graphite - sourced at its wholly owned Lac Knife, Québec deposit - from 95% to 99.99% purity using a proprietary energy efficient purification process. Attaining a 99.99% purity level from fine graphite flake is significant. Focus now has the technology to economically purify low value fine flake graphite or, "fines" to a high value material needed for the production of lithium-ion batteries.
