Four development scenarios being assessed
with a new mine plan and expanded mill throughput rate and
improvements to the cobalt and bismuth downstream
process
Issued Capital: 347,303,220
LONDON, ON, June 6, 2019 /CNW/ - Fortune Minerals Limited
(TSX: FT) (OTCQX: FTMDF) ("Fortune" or
the "Company") (www.fortuneminerals.com) is pleased to
provide a progress report on the study nearing completion by Hatch
Ltd. ("Hatch"), P&E Mining Consultants Inc.
("P&E") and Micon International Limited ("Micon")
updating the 2014 National Instrument 43-101 Technical Report on
the NICO Project Feasibility Study ("Technical Report"). The
updated Technical Report is assessing the economics of four
different development scenarios for the Company's 100% owned NICO
Cobalt-Gold-Bismuth-Copper Project ("NICO Project"),
including a vertically integrated project with a refinery in
southern Canada as originally
contemplated as well as lower capital cost options that involve
selling gold and concentrates from the mine site in the
Northwest Territories. The study
will be based on current capital and operating costs and currency
exchange rates at a 30% expanded throughput rate of 6,000 tonnes of
ore processed in the mill per day and longer term commodity prices
reflecting metal market dynamics. Hatch has also completed value
improvement studies for a number of unit operations that are being
engineered for inclusion in the updated Technical Report. In
particular, changes to the cobalt and bismuth downstream process,
together with the higher throughput rate, will help mitigate
increases in capital costs from escalation and reduce commissioning
and operational risks. They will also result in the production of a
superior cobalt sulphate product to the one produced in Fortune's
earlier pilot plants.

Cobalt Market:
The NICO deposit is a Canadian primary
cobalt deposit, which also contains more than one million ounces of
gold and approximately 12% of global bismuth in the current Mineral
Reserves (see Fortune news release, dated April 2, 2014). It is one of the few advanced
projects in the world to support near-term accelerating demand for
cobalt in new technologies. Cobalt is an essential ingredient in
most lithium-ion batteries used to power portable electronic
devices, transformative automotive electrification, and to store
energy from renewable sources and off-peak charging to make
electricity use more efficient. As a Canadian vertically integrated
development, the NICO Project will also reduce the risks of
geographic concentration of supply in the politically unstable
Democratic Republic of the Congo
(73% of 2018 mine production), and similar to the policy risks
associated with rare earth metals, China's dominance of refined cobalt products
(64% of 2018 refinery production and 85% of cobalt chemicals).
Bismuth is an eco-metal used primarily in the automotive and
pharmaceutical industries and has growing demand as a non-toxic and
environmentally safe replacement for lead.
Development Scenario Options:
Fortune has executed
Confidentiality Agreements with more than 45 companies interested
in participating in the development of the NICO Project and/or
securing a reliable Canadian and ethical supply of cobalt. These
companies are from diverse business sectors and have different
objectives with respect to the types of products they require and
their expectations for financial return verses supply chain
transparency and security of supply for raw material procurement.
Fortune is assessing the following different development scenarios
for the Technical Report to support project finance and strategic
partnership negotiations:
Scenario 1)
Produce cobalt and bismuth concentrates at the mine site and ship
these to the Company's proposed refinery in southern Canada for downstream processing to gold doré,
cobalt sulphate, bismuth ingot and copper cement
Scenario 2)
Only the mine site facilities are constructed with cobalt and
bismuth concentrates produced in the concentrator and gold
recovered by cyanide leaching of the concentrates to produce gold
doré, and cobalt and bismuth concentrates, then sold to third party
processors.
Scenario 3)
Gold doré and cobalt and bismuth concentrates are produced at the
mine site with gold and bismuth concentrate sold to third party
processors and the cobalt concentrate shipped to a lower capital
cost refinery in southern Canada
for processing to cobalt sulphate.
Scenario 4)
Cobalt and bismuth concentrates are produced at the mine site and
shipped to the refinery in southern Canada for downstream processing to gold doré,
a cobalt carbonate intermediate product, bismuth ingot and copper
cement.
In order to provide the Company with the flexibility to pursue
Scenarios 2) and 3), and/or if construction of the downstream
refinery in southern Canada is
deferred, gold would need to be recovered from the cobalt and
bismuth concentrates at the mine site instead of from the combined
autoclave leach residue at the refinery. Additional test work was
completed over the past few months in Lakefield, Ontario at SGS Canada Ltd. ("SGS
Lakefield"), which confirmed
that good recoveries for gold can be achieved from a combination of
gravity and flotation concentration and subsequent cyanide leaching
of each of the cobalt and bismuth concentrates (see Fortune news
release, dated May 3, 2019).
Cobalt Process Improvements:
Hatch conducted a value
improvement assessment of the cobalt process that was previously
contemplated in the 2014 Micon Feasibility Study (see Fortune news
release, dated April 2, 2014) and
2012 Front End Engineering and Design ("FEED") study by Aker
Solutions Canada Inc. (now Jacobs Minerals Canada
Inc.) (See Fortune news
release, dated July 2, 2012). A
number of improvements were identified that could reduce the
capital cost of the refinery by up to $200
million. These are being incorporated into the updated
Technical Report and will mitigate some of the increase in capital
costs that have resulted from escalation, other improvements and
the increase in throughput rate.
A summary of the improvements in the cobalt process
includes:
1) increasing the temperature and pressure in the
autoclave to 215 ̊ C and 2,795 kPa, respectively, to reduce
downstream process equipment;
2) Recirculation of autoclave leach liquor and higher
metal ion concentrations to reduce equipment sizes;
3) Test work was also conducted at SGS Lakefield to
validate the re-design of the copper cementation circuit and
recycling of bleed streams to mitigate cobalt recovery losses;
4) Sequential neutralization of the autoclave discharge
will now also remove manganese in addition to iron and arsenic,
eliminating a previously contemplated manganese removal step;
5) Addition of cobalt carbonate precipitation and
dissolution (previously piloted by Fortune) and ion exchange
purification circuits replacing solvent extraction to improve
cobalt purity and reduce costs;
6) As a lower capital cost option, the process can
terminate with the production of a cobalt carbonate intermediate
product for sale; and
7) Cobalt sulphate is otherwise then crystallized as
before.
In addition to mitigating increases in capital costs, the value
improvements by Hatch are expected to produce a superior cobalt
sulphate product from that produced in earlier pilot plant tests at
SGS Lakefield. The changes also enable Fortune to produce a cobalt
carbonate intermediate product if a phased development for the
refinery has strategic or economic advantage. The Hatch Metsim
modelled product specifications for both cobalt sulphate and
carbonate are shown below.

Bismuth Process Improvements:
Hatch has also made
improvements to the bismuth process flow sheet from the 2014 Micon
Feasibility Study and 2012 FEED study that are expected to reduce
process and commissioning risks. Bismuth concentrate would be
subjected to ferric chloride leach as previously contemplated.
However, instead of counter current electro-winning of an impure
cathode, a bismuth oxychloride is precipitated, which is then
smelted in a rotary furnace to pour 99.995% (4N) bismuth
ingots.
Other Project Improvements:
The updated Technical
Report will be based only on open pit mining. A production scale
underground ramp and two mining levels have already been developed
for potential underground mining of gold-rich deeper ores in the
deposit. However, selective underground mining will only be pursued
as an opportunity option if conditions warrant. Other changes to
the mine plan and schedule include a grade control and stockpiling
strategy to optimize the mining sequence and defer the processing
of lower grade ores (see Fortune News Release, dated March 27, 2018).
An airstrip has now been included in the mine site facilities to
enable construction from the existing winter ice road and allow the
project schedule to be aligned with the availability of the Tlicho
Road that will allow year-round access to the NICO Project.
Construction of the Tlicho Road is expected to commence later this
year for completion in 2022. This road is being developed under a
P3 financing, construction and operation structure between the
Northwest Territories government
and North Star Infrastructure GP, a syndicate including the Tlicho
Government, Kiewit Canada Development Corp., Hatch Corporation and
Thurber Engineering Ltd. (see Fortune news release, dated
February 14, 2019). The federal
government is contributing 25% of the construction costs. Mine site
power supply and heat will be supplied by liquid natural gas
("LNG") generators. LNG is a lower cost fuel than diesel and will
also reduce the carbon foot print for the mine. While the NICO mine
site is located only 25 km from the Snare Hydro complex, an
expansion would be required to supply all of the power demands of
the mine site.
The bulk concentrate regrind and secondary flotation circuits
that separate bismuth and cobalt from the bulk rougher concentrate
have also been moved from the refinery to the mine site in order to
enable the sale of concentrates as a development option.
The NICO Project is a development stage asset consisting of a
planned mine, mill and concentrator in the Northwest Territories and an option for the
construction of a cyanide leach and Merrill-Crowe facility to
recover gold as doré at the mine site. The vertically integrated
base case development scenario contemplates a hydrometallurgical
refinery in southern Canada to
process concentrates from the mine to value added products. Fortune
has an option to purchase lands in Saskatchewan for this refinery and is also
evaluating other greenfield and brownfield sites to build this
facility to accelerate development.
The updated Technical Report is nearing completion with the
aforementioned refinements and optimizations. Fortune and its
consultants are currently finalizing capital and operating cost
estimates for inclusion in the report and financial model. The
engineering for the Technical Report is otherwise essentially
complete subject to minor refinements. The Company is also updating
its electronic data room to enable companies under confidentiality
agreement to evaluate the new process changes and developments,
operational and product optionality, and current and future
economic potential in a market of accelerating cobalt demand and
supply chain concerns.
