FPX Nickel Reports Positive Field Tests Demonstrating Potential
for Significant Carbon Capture at Baptiste Nickel Project
Vancouver, February 16, 2021 – FPX Nickel Corp. (FPX-TSX.V) (“FPX” or the “Company”) is pleased
to report the results of initial field tests which demonstrate the potential for significant direct air carbon
capture in tailings at its Baptiste Project in the Decar Nickel District in central British Columbia. The field
tests, conducted by researchers from the University of British Columbia (“UBC”) funded by FPX and the
Government of Canada, demonstrate that the Baptiste Project’s tailings can sequester significant quantities
of carbon dioxide (“CO2”) when exposed to air through a natural process of mineral carbonation.
Highlights
• Carbon sequestration rates observed during the 24-day field program in August 2020 are consistent
with and, under certain conditions, improve upon the rates achieved in previous laboratory -based
testing
• Significant rates of carbon sequestration were noted on a continuous basis throughout the program
under all test conditions, with the h ighest rates of sequestration occurring in tailings subjected to
churning at daily intervals to encourage greater exposure of the crushed material to air
• Measurements during the 24-day field program last August indicate capture of a total of 2 grams
of CO2 for each kilogram of crushed Baptiste tailings exposed to air by churning on a daily basis
to a depth of 12 centimetres
• The experimental results indicate reaction with only 15-30% of the available carbon -reactive
mineral (brucite) in the tailings, suggesting promising future opportunities to optimize the reaction
between tailings and CO2 in air to achieve even higher rates of carbon capture
Cautionary Statement: The test resul ts described herein are preliminary in nature and may not be
representative of conditions or results in an operating environment, particularly as it pertains to the
representativeness of mineralization, moisture content , changes in weather conditions, process water
chemistry and tailings emplacement configuration , including the rate at which tailings are covered with
fresh material, among other parameters. There is no certainty that the results reported herein will be
realized in an operating environment. Further studies are recommended to expand the scale of testing to
better understand the potential for carbon sequestration to be realized in an operating environment.
“These exciting results mark an important step in our objective to develop Baptiste as the world’s first
large-scale, carbon -neutral nickel operation,” commented Martin Turenne, FPX Nickel’s President and
CEO. “Having previously established that Baptiste has the potential to be the world’s lowest-carbon source
of refined nickel (see FPX’s news release dated January 12, 2021), we will continue to advance our
understanding of the Project’s carbon sequestration potential, with further results of the 2020 test program
anticipated in the second quarter of 2021, and a new, larger field trial planned for this later this year.”
The test program, conducted at a site approximating the climactic conditions of an eventual operation at the
Decar Nickel District, builds on more than a decade of research on technologies that maximize the reaction
between CO2 and brucite (mineral form of magnesium hydroxide) present in the Baptiste mine tailings. In
a natural process called carbon mineralization, CO2 reacts with brucite in the tailings, binding the CO2 in a
benign, solid magnesium carbonate.
The test work summarized herein was completed at an outdoor site in Prince George from August 5 -29,
2020 on a representative Baptiste mineralized composite of approximately 300 kilograms comprised of core
sample reject material crushed to 50 -360 µm, consistent with the tailings size anticipated during mine
operation. Chemical analysis of the core material indicated 1-2 wt% content of brucite, a range consistent
with the average brucite content of the Baptiste deposit.
The tailings sample was divided into splits of 37 kilograms loaded to a depth of 12 centimeters into eight
cells in two l arge containers, with local water added to achieve a moisture content of approximately 15
wt%. One container was exposed to local weather conditions (including precipitation and solar radiation),
while the second was placed under a shade tent to control t he water content of the tailings , which was
maintained approximately constant by the manual addition of water from time to time.
Two physical manipulations, churning and aeration, were each applied to four of the eight cells, with the
four remaining cells left undisturbed as controls. In the churned cells, the tailings were manually overturned
once per day to a depth of 12 centimetres. In the aerated cells, narrow holes with a diameter of 1 cm were
bored on a 5 cm grid from the surface to the bottom of the cell to encourage a greater exposure of air to the
crushed material.
Two methodologies were employed to confirm the amount of carbon sequestered during the test program.
In the field, CO2 fluxes were quantified using a dynamic closed system CO2 flux chamber, which measures
the concentration of CO2 in the headspace above the tailings. These measurements are taken on a regular
basis throughout the test period. A decrease in headspace CO 2 concentration measures the influx of CO2
into the tailings. Core samples collected at the end of the experiment were submitted for analysis of total
inorganic carbon ( “TIC”) together with blind standards. Comparison of total captured CO 2 shows good
agreement between the flux and TIC measurement methodologies and provides greater assurance regarding
the measured rate of carbon capture.
In the cells churned to a depth of 12 centimetres once per day, carbon absorption measurements demonstrate
capture of 2 grams of CO2 for each kilogram of crushed Baptiste tailings in the cell over the course of the
24-day trial period in August, and with no deposition of new tailings on top . Based on this amount of
carbon sequestration, it is estimated that only 15 -30% of the brucite reacted with carbon dioxide, leaving
70-85% of the brucite available for reaction.
In the control and aerated cells, an average of 1 gram of CO 2 was captured for each kilogram of crushed
Baptiste tailings in the cells over the course of the field trial , representing approximately 50% of the
sequestration rate observed in the churned cells . The aeration techniques employed during the field trial
showed negligible benefit on the rates of carbon sequestration as compared to the control samples.
Rates of carbon capture in the churned cells exceed the rates achieved in undisturbed tailings during
previous laboratory -based testing , as documented in a study published in the International Journal of
Greenhouse Gas Control (“Prospects for CO2 mineralization and enhanced weathering of ultramafic mine
tailings from the Baptiste nickel deposit in British Columbia, Canada”, Power et al., 2020).
Consistent with previous lab testing, these field test results confirm that the principal rate -limiting factor
for the Baptiste tailings on the amount of carbon sequestration is the delivery of CO2 to the brucite contained
in the tailings . Further work on a larger sample is being planned to investigate engineering options to
increase the rate and duration of contact between air and the surface area of the tailings to achieve a greater
rate of sequestration.
Next Steps
The results summarized herein are from the first of two phases of this initial UBC field program conducted
in 2020. On completion of the first phase of testing in Prince George in August, the tailings were moved
to Vancouver and a second extended stage was conducted outdoors in Vancouver from September to
November. Testing during this second stage assessed the rate and quantity of carbon capture by exposure
of Baptiste material to air. Additional testing assessed the rate and quantity of carbon capture from injection
of concentrated CO2 gas. The Company expects to report the final findings of the entire 2020 test program
in the second quarter of 2021.
The Company will expand the scope of carbon sequestration testing in 2021, and expects to announce the
details of those planned activities in con nection with the publication of the final 2020 field test results in
the second quarter.

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 British Columbia. The District
is a two-hour drive from Fort St. James on a high-speed logging road.
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. Since 2010, approximately US $24 million has
been spent on the exploration and development of Decar.
Of the four targets in the Decar Nickel District, the Baptiste Deposit, which was initially the most accessible
and had the biggest known surface footprint, has been the main focus of diamond drilling since 2010, with
a total of 82 holes and over 31,000 metres of drilling 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 the current NI 43-101 resource estimate, having an effective date of September 9, 2020, the
Baptiste Deposit contains 1.996 billion tonnes of indicated resources at an average grade of 0.122% DTR
nickel, containing to 2.4 million tonnes of nickel, plus 593 million tonnes of inferred resources with an
average grade of 0.114% DTR nickel, containing 0.7 million tonnes of nickel, both reported at a cut -off
grade of 0.06% DTR nickel. Mineral resources are not mineral reserves and do not have demonstrated
economic viability.
