TSX: DIAM
SASKATOON, May 15, 2018 /CNW/ - George H. Read, P. Geo., Senior Vice President
Exploration and Development of Star Diamond Corporation ("Star
Diamond" or the "Corporation") is pleased to announce that Rio
Tinto Exploration Canada ("RTEC"), and Consulmet (Pty) Ltd
("Consulmet") have finalized contractual arrangements for the
manufacture and supply of a 30 tonne per hour ("tph") bulk sample
plant. This bulk sample plant will be used to process the
kimberlite recovered by the next phase of large diameter, bulk
sample drilling on the Star - Orion South Diamond Project
("Project"). The bulk sample plant will be fabricated by Consulmet
in South Africa in modular,
containerized units, which will facilitate shipment to the Project
site in central Saskatchewan.
Consulmet is a specialised technology company serving the minerals
industry through the design and supply of production ready mineral
processing plants.
Bulk Sample Plant
The proposed bulk sample plant will use a modern flowsheet and
the latest X-ray transmission ("XRT") sorting technology to ensure
any large diamonds present (up to 25 millimetres) are recovered
with minimal breakage. A secondary crushing circuit, using a high
pressure rolls crusher ("HPRC"), will maximize the liberation of
smaller diamonds from the kimberlite. The bulk sample plant
consists of four areas, each with its own control system: 1) a wet
front-end and feed preparation area; 2) an XRT sorter area; 3) a 10
tph dense media separator ("DMS") area; and 4) a water reticulation
area.
Washed Run of Mine ("ROM") kimberlite (-80 millimetres),
collected in bulk bags, from Bauer Maschinen GmbH ("Bauer") BE550
desanding equipment at the drill site, will be supplied to the
front-end of the plant. Initial scrubbing and screening sends
coarse -80+25 millimetre kimberlite to the jaw crusher, and removes
all -0.85 millmetre fines using a slotted screen. Thereafter,
-25+12 and -12+6 millmetre kimberlite fractions are processed
through the XRT sorter in two simultaneous feeds. The XRT sorter
accepts are stored in a secure bin for subsequent diamond recovery.
The -25+6 millimetre XRT sorter rejects are sent to a secondary
HPRC and the crushed product is returned to the primary feed. The
-6+0.85 millimetre kimberlite fraction is processed through the DMS
cyclone to prepare a diamond-bearing heavy mineral concentrate.
Final diamond recovery is to be conducted at a secure off-site
facility. Plant process water is recovered from various de-watering
screens within the plant and the fines thickener, and returned to a
recycled water storage facility. Fresh and recycled water are used
in the primary plant feed. The underflow from the thickener (-0.85
millimetre) is sent as residue to an on-site fines management area
("FMA").
Senior Vice President Exploration and Development, George Read, states: "Star Diamond Corporation
is in complete support of the design and equipment selection for
the bulk sample plant. The modern flowsheet and
state-of-the-art XRT sorting technology used in this plant will
replicate the flowsheet and equipment of the processing plant that
would be used on a potential future diamond mine. This bulk sample
plant is specifically designed to maximize liberation and recovery
of diamonds throughout the -25+0.85 millimetre size range, and
minimize diamond breakage, particularly among potential specials
(plus 10.8 carat stones) that may be recovered from both the Star
and Orion South Kimberlites."
About Star Diamond Corporation
Star Diamond Corporation is a Canadian based corporation engaged
in the acquisition, exploration and development of mineral
properties. Shares of the Corporation trade on the TSX Exchange
under the trading symbol "DIAM". The Corporation's Star - Orion
South Diamond Project is located in central Saskatchewan some 60 kilometres east of the
city of Prince Albert. The Project is in close proximity to
established infrastructure, including paved highways and the
electrical power grid, which provide significant advantages for
future mine development.
The Corporation recently announced the positive results of the
independent Preliminary Economic Assessment ("PEA") on the Project.
The PEA estimates that 66 million carats of diamonds could be
recovered in a surface mine over a 38-year Project life, with a Net
Present Value ("NPV") (7%) of $2.0
billion after tax, an Internal Rate of Return ("IRR") of 19%
and an after-tax payback period of 3.4 years after the commencement
of diamond production (see News Release dated April 16, 2018). Star
Diamond commissioned the PEA and related Technical Report
for the Star and Orion South Kimberlites and, as such, the PEA and
Technical Report are the sole responsibility of the Corporation.
The PEA is based on exploration and evaluation work conducted up to
and including March 2017.
During 2017, the Corporation granted RTEC an option to earn up
to a 60% interest in the Corporation's Fort à la Corne mineral
properties (including the Star-Orion South Diamond Project) on the
terms and conditions contained in the Option Agreement (see News
Release dated June 23, 2017).
Completion of the proposed 2018 sampling program (First Option)
does not entitle RTEC to an interest in the Corporation's 100
percent held Fort à la Corne mineral properties (including the
Project).
