VANCOUVER, British Columbia, Sept. 16, 2022 (GLOBE NEWSWIRE) — Search Minerals Inc. (TSXV: SMY | OTCQB: SHCMF) (“Look for“or the”Company”), is pleased to announce that two bulk samples of mineralization from Deep Fox and Foxtrot have been processed in our STAGE 1 magnetic separation program at SGS Canada (Lakefield) (“SGS”). The Deep Fox sample includes 53 metric tons recovered from the exposed surface of the deposit. Similarly, the Foxtrot sample includes 20 tons of surface material.
The SGS the program involved bench-scale work to test the ability of the two samples to magnetically separate, then running a continuous pilot plant operating at approximately 550 kg per hour of feedstock over 15 pilot plant periods to produce iron pre-concentrate by Low Intensity Magnetic Separation (LIMS) and rare earth concentrate by Wet High Intensity Magnetic Separation (WHIMS) and final tailings material for environmental testing.
Results from the magnetic separation pilot plant on the two bulk samples were as expected.
Highlights of the program were,
- Total rare earth recoveries were high, at 88-90% for Deep Fox and 84-85% for Foxtrot.
- Rare earth concentrate grades increased from ~1% TREO+Y to 3.2% TREO+Y for Deep Fox and 3.7% TREO+Y for Foxtrot.
- Pilot plant testing demonstrated good magnetic separation performance at a coarser primary grind size (P80 ~100 µm) than that of the batch tests.
- Metallurgical performance was stable throughout the pilot plant operation.
- In total, approximately 13.8 tonnes of Deep Fox rare earth concentrate and approximately 5.1 tonnes of Foxtrot rare earth concentrate were produced.
- Deep Fox and Foxtrot rare earth concentrates will be used in Search’s Phase 2 development program as part of the Sprint to Production to extract and recover a high quality/high purity mixed rare earth concentrate product using Search’s direct extraction technology.
- A total of approximately 1.74 tonnes of Deep Fox LIMS concentrate grading 94.9% Fe2O3 and ~1.2 tonnes of Foxtrot grading 87.4% Fe2O3 have been recovered and will be studied as a potential by-product, namely: iron ore.
- About 5 tons of non-magnetic materials were collected after the magnetic separation. This material will be characterized for disposal of dry piled tailings and possible use of by-products as sand material for the construction industry.
Dr. David Dreisinger, Director/Vice President of Metallurgy States; “The test results on both bulk samples were as expected and provide a basis for ‘scaling up’ the commercial installation. The availability of approximately 18.9 tonnes of rare earth concentrate allows us to move on to our larger scale testing of the direct extraction process. The benefit of producing a concentrate, using grinding and magnetic circuit, prior to our proprietary direct extraction process, is reduced equipment size and reduced chemical and energy use. to achieve similar overall recoveries of marketable rare earth elements.
Greg Andrews, Chairman and CEO says; “We are continuing 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 that create value in the rare earths supply chain.When producing the oxides, we seek co-funded government programs to process the 18.9 tons of rare earth concentrate using our proprietary direct mining process to produce approximately 1 ton of mixed rare earth oxide concentrate for further separation processing. the transformation of the oxides of permanent magnets into metal as a precursor to the manufacture of magnets.

About Search Minerals Inc.
Led by a proven management team and Board of Directors, Search is focused on finding and developing Critical Rare Earth Element (CREE), Zirconium (Zr) and Hafnium (Hf) resources in the Emerging District. of Port Hope Simpson – St. Lewis CREE of South East Labrador. Search controls two fields (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 belt of 64 km long forming an REE district in Labrador. Search has completed a preliminary economic assessment report for DEPTH and FOXTROT. Search is also working on three exploration prospects along the belt, including: FOX MEADOW, SILVER FOX and AWESOME FOX.
Search continued to optimize its patented direct extraction process technology with support from the Department of Industry, Energy and Technology, the Government of Newfoundland and Labrador and the economic promotion of Atlantic Canada. 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 acknowledge the Government of Newfoundland and Labrador’s continued support of its junior exploration program.
Search Minerals has been selected to participate in the Government of Canada’s Accelerated Growth Service (“AGS”), which supports high-growth businesses. AGS, as a “one-stop-shop” model, provides Search with coordinated access to Government of Canada resources as Search continues to rapidly transition to production and helps build a North American supply chain and European stable and secure in rare earth elements.
