Vancouver, February 25, 2019 – FPX Nickel Corp. (FPX-TSX.V) (“FPX Nickel” or the “Company”) is pleased to announce positive results from metallurgical testing on the Baptiste Deposit at its 100%-owned Decar Nickel District (the “Project”) in central British Columbia.  The metallurgical testing achieved meaningful improvements over the results of previous metallurgical test work used as a basis for the Project’s 2013 preliminary economic assessment (“2013 PEA”), demonstrating significant increases in estimated nickel recovery and final concentrate quality, using conventional processing technologies.


  • Conventional flowsheet based on grinding, magnetic separation and flotation processes
  • Consistent production of nickel (“Ni”) concentrates with improvements in grade and recovery, versus 2013 PEA projections, as shown in Table 1 below
  • Consistent production of iron ore concentrates grading up to 64% iron (“Fe”) content, the first successful generation of a potentially commercial by-product in the Project’s testing history

A comparison of the results of the 2019 metallurgical test program with the assumptions in the 2013 PEA is provided in Table 1.

“These metallurgical results confirm an important technical breakthrough for the Decar Project,” commented Martin Turenne, the Company’s President and CEO. “The confirmation of a simple, robust flowsheet using conventional magnetic separation and flotation parameters paves the way for Decar’s ongoing development, and for the exploration and development of awaruite nickel targets generally.  The substantial increase in projected DTR nickel recoveries from 82% in the 2013 PEA to up to 90% demonstrates the strong metallurgical performance of the Baptiste deposit.  The consistent production of concentrates grading from 55% to 72% nickel further establishes the potential for the Baptiste deposit to generate a clean nickel product with no sulphur and very high metal content.”

Mr. Turenne continued, “We also note the successful production of a high iron-content by-product, which provides the basis to investigate the potential implications of an entirely new product stream on the Project’s economics.  We will continue to advance this metallurgical program through further optimization testing and trade-off studies to optimize the components of an updated mine plan for the Baptiste Deposit.”

Description of Metallurgical Test Work

The metallurgical testing was conducted at ALS Metallurgy in Kamloops, British Columbia and overseen by Jeffrey B. Austin, P. Eng., President of International Metallurgical and Environmental Inc.  The test work was completed on a representative mineralized composite measuring approximately 400 kilograms comprised of core sample reject material from four drill holes completed in 2012 and 2017 in the southeastern portion of the Baptiste Deposit.

The metallurgical study consisted of two phases of testing.  Phase 1 was focused primarily on magnetic separation of magnetic materials from non-magnetic materials in the composite material.  Approximately 75 percent of the contained nickel in the Baptiste Deposit occurs as awaruite, a highly magnetic nickel-iron alloy that is readily recovered by low-intensity magnetic separation.  The deposit also contains significant magnetite (iron oxide), which is recovered concurrently with the awaruite in magnetic separation.  Phase 1 test work confirmed the recovery of nickel and iron using magnetic separation and the upgrading of these minerals into a bulk Ni-Fe concentrate using re-grinding and magnetic cleaning.

Phase 2 involved flotation tests on magnetic concentrates produced in Phase 1 to enable the separation of awaruite from magnetite for the production of two concentrates: a nickel concentrate grading from 55% to 72% Ni and 25% Fe, and a magnetite iron ore concentrate grading from 58% to 64% Fe.  The high-grade nickel concentrate produced during the testing program approximates the composition of pure awaruite, a nickel-iron alloy comprised of approximately 75% Ni and 25% Fe.

Phase 2 testing confirmed that the separation of nickel from a bulk Ni-Fe concentrate can be achieved using traditional flotation processes.  Test work at ALS included open circuit testing of nickel recovery to evaluate reagent options, liberation requirements in flotation, and retention time requirements.  The flotation process uses copper sulphate to facilitate the attachment of flotation collectors to the awaruite mineral surface in a manner that mirrors conventional zinc flotation processes.  Flotation collector 3418A, an industry standard reagent, was used in the flotation process.

The tailings stream from the nickel flotation process is a high-grade iron concentrate which testing has shown to contain 58 to 64% iron.  The Company plans further evaluative work to examine the commercial potential of this iron ore concentrate, including an evaluation of the possible impact on the Project’s economics.

In summary, the production of a 55% to 72% nickel concentrate and an iron ore concentrate grading 58 to 64% Fe from the Baptiste composite sample with a feed grade of 0.145% DTR Ni is based on traditional grinding, magnetic separation and flotation processes; a flowsheet is shown in Figure 1.  Unit operations in this flowsheet include crushing, grinding to 120-360 microns (P80), magnetic separation with a mass pull of 10-15%, magnetic concentrate re-grinding to 25 microns (P80), rougher flotation concentrate production and flotation cleaning.

The expected metallurgical performance of the test sample, based on test work completed at ALS Metallurgy, is summarized in Table 2.

These results were obtained with a consistent set of metallurgical parameters across all test samples and demonstrate a significant improvement over test work completed for the 2013 PEA, demonstrating higher nickel recoveries, higher nickel grade in the final concentrate and a lower mass pull in magnetic separation.  The recovery and concentrate grade assumptions in the 2013 PEA were based on a two-stage process consisting of a primary coarse grind to P80 600 microns, followed by rougher magnetic separation with an estimated mass pull of 33%, then a re-grind of that fraction to P80 70 microns followed by Knelson gravity concentration to produce a concentrate grading 13.5% nickel, 45-50% iron and 1-2% chromium.  The projected recoveries in the 2013 PEA were 82% of the DTR nickel (see 2013 PEA filed under the Company’s SEDAR profile on August 21, 2013).

Future Metallurgical Test Work

The Company will undertake further metallurgical test work in 2019 to evaluate the following aspects of metallurgical performance:

  • Optimization of the flotation process for the production of high-grade nickel concentrates, including evaluation of reagent quantities and locked-cycle test performance
  • Optimization of the quality of the iron ore concentrate produced as a by-product of the nickel recovery process
  • Detailed evaluation of minor elements in the nickel concentrate and iron ore concentrate
  • Leach testing to evaluate the amenability of magnetic and flotation concentrates to the production of a high-grade nickel solution

Cautionary Note Regarding 2013 PEA

The 2013 PEA, by definition, is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves.  There can be no certainty that the PEA will be realized.  It is important to note that mineral resources are not mineral reserves and do not have demonstrated economic viability.

About the Decar Nickel District

The Company’s Decar Nickel District claims cover 245 square kilometres of the Mount Sidney Williams ultramafic/ophiolite complex, 90 km northwest of Fort St. James in central BC. The District is a two hour drive from Fort St. James on a high-speed logging road.  A branch line of the Canadian National Railway is less than 5 kilometres east from Decar’s Baptiste Deposit and the BC Hydro power grid comes within 110 kilometres south of the property.

Decar hosts a greenfield discovery of nickel mineralization in the form of a naturally occurring nickel-iron alloy called awaruite, which is amenable to bulk-tonnage, open-pit mining. Awaruite mineralization has been identified in four target areas within this ophiolite complex, being the Baptiste Deposit, the B Target, the Sid Target and Van Target, as confirmed by drilling in the first three plus petrographic examination, electron probe analyses and outcrop sampling on all four.

Of the four targets in the Decar Nickel District, the Baptiste Deposit has been the main focus of diamond drilling from 2010 to 2017, with a total of 82 holes completed.  The Sid Target was tested with two holes in 2010 and the B Target had a single hole drilled into it in 2011; all three holes intersected nickel-iron alloy mineralization over wide intervals with DTR nickel grades comparable to the Baptiste Deposit.  The Van Target was not drill-tested at that time as rock exposure was very poor prior to logging activity by forestry companies.

As reported in a NI 43-101 resource estimate prepared on February 26, 2018, the Baptiste deposit contains 1.843 billion tonnes of indicated resources at an average grade of 0.123% DTR nickel, for 2.3 million tonnes of DTR nickel, and 391 million tonnes of inferred resources with an average grade of 0.115% DTR nickel, for 0.4 million tonnes of DTR nickel, reported at a cut-off grade of 0.06%.  Mineral resources are not mineral reserves and do not have demonstrated economic viability.
