Search Minerals Completes Magnetic Separation of Bulk Samples at SGS Canada
16 Setembro 2022 - 12:29PM
Search Minerals Inc. (TSXV: SMY | OTCQB:
SHCMF) (“
Search” or the
“
Company”), is pleased to announce that two bulk
samples of mineralization from Deep Fox and Foxtrot have been
processed in our
PHASE 1 magnetic separation
program at SGS Canada (Lakefield) (“
SGS”). The
Deep Fox sample comprises 53 metric tonnes recovered from the
exposed surface of the deposit. Similarly, the Foxtrot sample
comprises 20 tonnes of surface material.
The SGS program involved bench
scale work to test the amenability of the two samples to magnetic
separation and then the execution of a continuous pilot plant
operating at ~550 kg per hour of feed material over 15 separate
pilot plant periods to produce a pre-concentrate of iron by Low
Intensity Magnetic Separation (LIMS) and a rare earth concentrate
by Wet High Intensity Magnetic Separation (WHIMS) and a final
tailing material for environmental testing.
The results of the magnetic separation pilot
plant on the two bulk samples were in line with expectations.
Highlights of the program were,
- The total rare earth recoveries
were high, at 88-90% for Deep Fox and 84-85% for Foxtrot.
- The rare earth concentrate grades
were upgraded from ~1% TREO + Y to 3.2% TREO + Y for Deep Fox and
3.7% TREO + Y for Foxtrot.
- The pilot plant testing
demonstrated a good magnetic separation performance at a coarser
primary grind size (P80 ~100 µm) than that of the batch tests.
- The metallurgical performance was
steady over the pilot plant operation.
- A total of ~13.8 tonnes of Deep Fox
Rare Earth Concentrate and ~5.1 tonnes of Foxtrot Rare Earth
Concentrate were produced.
- The Deep Fox and Foxtrot Rare Earth
Concentrates will be used in Search’s Phase 2 development program
in the Sprint to Production to extract and recover high grade/high
purity mixed rare earth concentrate product using Search’s Direct
Extraction Technology.
- A total of ~1.74 tonnes of Deep Fox
LIMS concentrate grading 94.9% Fe2O3 and ~1.2 tonnes of Foxtrot
grading 87.4% Fe2O3 were recovered and will be studied as a
potential by-product, ie: iron ore.
- Approximately 5 tonnes of
non-magnetic material were collected after the magnetic separation.
This material will be characterized for dry-stackable tailings
disposal and possible by-product use as a sand material for the
construction industry.
Dr. David Dreisinger, Director/Vice-President of
Metallurgy states; “The results of the testing on the two bulk
samples were in line with expectations and provide a basis for
“scale up” of the commercial facility. The availability of
approximately 18.9 tonnes of rare earth concentrate allows us to
move to our larger scale testing of the Direct Extraction Process.
The benefit of producing a concentrate, using the grinding and
magnetic circuit, prior to our proprietary Direct Extraction
Process, is the reduction in size of equipment and reduced chemical
and energy use to obtain similar overall recoveries of saleable
rare earth elements.”
Greg Andrews, President/CEO states; “We continue
with our “Sprint to Production” and this is a very important step
to scale up and produce more material for further separation into
individual oxides of the permanent magnet material, Neodymium (Nd),
Praseodymium (Pr), Dysprosium (Dy) and Terbium (Tb). These are the
key elements which create the value in the rare earth element
supply chain. Upon producing the oxides, we are seeking co-funded
government programs to process the 18.9 tonnes of rare earth
concentrate using our proprietary Direct Extraction Process to
produce approximately 1t of mixed rare earth oxide concentrate for
further separation processing. Ultimately, Search will demonstrate
the transformation of the permanent magnet oxides into metal as a
precursor to magnet fabrication.”

About Search Minerals Inc.
Led by a proven management team and board of
directors, Search is focused on finding and developing Critical
Rare Earths Elements (CREE), Zirconium (Zr) and Hafnium (Hf)
resources within the emerging Port Hope Simpson – St. Lewis CREE
District of South East Labrador. Search controls two deposits
(Foxtrot and Deep Fox), two drill ready prospects (Fox Meadow and
Silver Fox) and numerous other REE prospects, including Fox Valley,
Foxy Lady and Awesome Fox, along a 64 km long belt forming a REE
District in Labrador. Search has completed a preliminary economic
assessment report for DEEPFOX and
FOXTROT. Search is also working on three
exploration prospects along the belt which include: FOX
MEADOW, SILVER FOX and AWESOME FOX.
Search has continued to optimize our patented
Direct Extraction Process technology with the support from the
Department of Industry, Energy ad Technology, Government of
Newfoundland and Labrador, and from the Atlantic Canada Opportunity
Agency. We have completed two pilot plant operations and produced
highly purified mixed rare earth carbonate concentrate and mixed
REO concentrate for separation and refining. We also recognize the
continued support by the Government of Newfoundland and Labrador
for its Junior Exploration Program.
Search Minerals was selected to participate in
the Government of Canada Accelerated Growth Service
(“AGS”) initiative, which supports high growth
companies. AGS, as a ‘one-stop shop’ model, provides Search with
coordinated access to Government of Canada resources as Search
continues to move quickly to production and contribute to the
establishment of a stable and secure rare earth element North
American and European supply chain.
