Development Capital

Mineral Adeptness Estimate

Exploration Upside

Craig Taylor, CEO of Aegis Metals, stated: “We are admiring to accept delivered a absolute PEA for the Wicheeda REE Activity that has the abeyant to be one of the top REE projects in the world. We chose SRK due to its apple chic acquaintance and acceptability in the mining industry and in accurate its adeptness to accumulate a aggregation with awful specialized adeptness of Attenuate Apple Elements projects. The after-effects of the PEA acknowledge the Wicheeda Activity demonstrates able-bodied economics and almost low antecedent CAPEX via a staged development book that provides the adaptability to capitalize on apprehension REE appeal pressure.”

Dr. Luisa Moreno, Director, added: “The Wicheeda activity has the three basic aspects for a acknowledged attenuate apple project, favorable minerology bedeviled by abject grained bastnasite ancestors minerals, a metallurgical activity that yielded aerial brand abutment apply and abounding basement in a affable jurisdiction. With the absolute PEA, the activity is assuredly a footfall afterpiece to production.”

PEA Key Metrics

Table 1: Key banking and activity metrics

Optimization Opportunities and Next Steps

The PEA describes a well-developed abject case abutment absorption and hydrometallurgical pre-leach-caustic crack-leach flowsheet able of accomplishing aerial REE recoveries into a alloyed REE beforehand product. The abject case represents a well-proven and broadly adopted REE accretion flowsheet.

There are several another activity and basement development options that accept apparent affiance in antecedent testing or based on the characteristics of Wicheeda REE augment are accepted to be viable, that accept the abeyant to crop simplifications that may accord to decreased CAPEX and/or operating costs (OPEX). Approaching analytic aisle bank and/or pilot-scale testwork and bread-and-butter trade-off, and adeptness admiration studies are planned which accommodate (but are not bound to):

Updated Mineral Resource

The Wicheeda drop is modelled as a southeast-trending, arctic to northeast dipping blended layered syenite-carbonatite axle circuitous accepting ambit of about 400 m north-south by 100-250 m east-west. The mineralization is interpreted as a moderately north-northeast dipping, shallowly arctic plunging, layered axle circuitous accepting low REE brand syenite at its base, overlain by capricious boilerplate REE brand amalgam xenolithic-carbonatite (fenite), and assuredly almost college REE brand dolomite-carbonatite rocks, which anatomy the basic mineralization of the Wicheeda REE drop aftereffect at surface.

The adapted MRE comprises a 5.0 actor tonnes Indicated Mineral Resource, averaging 2.95% TREO (Total Attenuate Apple Oxide: CeO2, La2O3, Nd2O3, Pr6O11, Sm2O3, Eu2O3, Gd2O3, Tb4O7, Dy2O3 and Ho2O3), and a 29.5 actor tonnes Accepted Mineral Resource, averaging 1.83% TREO, appear at a absolute brand of 0.5% TREO aural a conceptual Lerchs-Grossman (LG) pit carapace and is provided in Table 2.

The lower absolute brand was accustomed based on application of TREO and apply payable, metallurgical recovery, and operating amount assumptions.

The MRE is predominately based on an banausic geological archetypal and methodologies activated to account the 2020 MRE. Differences chronicle to the assimilation of lurid REE multi-element admixture inductively accompanying claret accumulation spectrometry (ICP-MS), re-assay of the 2008 and 2009 drillholes, abbreviation the ambiguity apropos the absolute abridged X-ray fluorescence analytic results, adapted admiration parameters, and a 2020 LiDAR survey. The added resolution of the LiDAR allows for added able-bodied abundance planning, decidedly aback because the aerial abatement aural the Activity area.

Table 2: Wicheeda Mineral Adeptness (effective date November 21, 2021)

Notes for Adeptness Table:

The PEA for the Wicheeda REE Drop is basic in nature, includes accepted mineral assets that are advised too abstract geologically to accept the bread-and-butter considerations activated to them that would accredit them to be categorized as mineral reserves, and there is no authoritativeness that the basic bread-and-butter appraisal forecasts will be accomplished or that any of the assets will anytime be upgraded to reserves. Mineral assets that are not mineral affluence do not accept accustomed bread-and-butter viability.

Table 3 aloft illustrates the acuteness of the MRE to altered absolute grades for a abeyant open-pit operation book with reasonable angle for bread-and-butter extraction. The clairvoyant is cautioned that the abstracts provided in these tables should not be interpreted as a account of mineral resources. Quantities and estimated grades for altered absolute grades are presented for the sole purpose of demonstrating the acuteness of the adeptness archetypal to the best of a specific absolute grade.

Mine Planning

SRK developed and evaluated a alternation of operational scenarios involving altered assembly ante and bartering articles to admission at an optimum band-aid for abundance development. An admission archetypal was acclimated to assay the acuteness of the drop adjoin assorted key variables, and assorted high-level schedules were costed and economically adjourned beneath capricious appraisement assumptions.

From this book analysis, a go-forward book was called for added refinement. An adapted pit admission was run to baddest a pit based on optimizing the antithesis of NPV and risk. This pit was the abject of a assembly agenda for the LOM.  Over the LOM, the activity will accomplish 26.1 Mt of comminute augment at a band arrangement of 1.75:1 (waste:mill feed) and an boilerplate brand of 2.3% TREO.

The Wicheeda drop will be mined as a accepted attainable pit operation. In-pit absorption for both comminute augment and decay will be by 65 tonne absorption trucks. Comminute augment will be mined in six-metre benches and hauled to the altercation abutting to the pit rim. Crushed comminute augment will be conveyed to the abutment mill.

Waste bedrock will be mined and hauled to an on-site bedrock accumulator adeptness as able-bodied as to the tailings accumulator adeptness (TSF) for beach construction.

The mining operation has been costed as buyer operated.

Flotation Concentrator

Material from the Wicheeda drop is to be candy in a abutment concentrator to aftermath a abutment apply that is added candy at the hydrometallurgical plant. The abutment concentrator is to absorb assemblage operations that are accepted to the industry and include: crushing and cutting to bear the REE minerals from the decay rock, followed by conditioning at animated temperature with the appropriate reagents followed by rougher and scavenger flotation. The consistent rougher-scavenger abutment apply is to be added upgraded during assorted stages of reagent conditioning and cleaner flotation. The upgraded abutment apply is again thickened, filtered and able for carriage to the hydrometallurgical bulb for added processing. The abutment concentrator tailings is to be pumped to the TSF for disposal.

An important aspect for a acknowledged rare-earth activity is the assembly of a abutment concentrate[2], and alone a baddest cardinal of companies accept been able to abode such achievement. A high-grade abutment apply leads to abate hydrometallurgy bulb accessories and appropriately appreciably lower basic expenditures. As lower volumes of mineral apply are processed, there are additionally operating costs allowances as beneath reagents are consumed.

Hydrometallurgical Plant

Flotation apply is subjected to a pre-leach activity application hydrochloric acerbic (HCl) to abolish gangue minerals that are present. The pre-leach antithesis is again candy by abrasive arise application a able sodium hydroxide (NaOH) band-aid at animated temperature. This converts the REE phosphate and fluorocarbonate minerals to hydroxides and attenuated phosphate, fluoride and carbonate species. The attenuated breed are precipitated application adhesive and the NaOH thereby regenerated and re-used. The REE hydroxide is leached with HCl, algae removed and the REE again precipitated with adhesive to anatomy a REE hydrate which is dried, packaged, and beatific to market.

As noted, NaOH acclimated is regenerated application adhesive and the hydrochloric acerbic is regenerated application sulphuric acid. Decay articles from the hydrometallurgical bulb abide mainly of gypsum, antithesis lime, calcium phosphate and carbonate and accessory metal precipitates. The hydrometallurgical antithesis is accumulated with the abutment tailings for storage.  

The hydrometallurgical bulb architecture abbreviated aloft is based on all-encompassing bench-scale hydrometallurgical testing by SGS Lakefield on aggregate samples of abutment apply produced during pilot bulb abutment operations on Wicheeda mineralized material. Hydrometallurgical testwork is continuing and will aftereffect in pilot bulb affirmation of the called process.

On-site Activity Infrastructure

Water Management

The Wicheeda Activity will abide of basement on the east and west extents of Wichcika Creek, and upstream of Wicheeda Lake. Baptize administration basement are appropriate to abduction the apparent baptize runoff and elimination from the attainable pit, decay bedrock accumulator facilities, comminute augment stockpiles, and the tailings accumulator facility.

A distinct accumulating pond bottomward beck of the pit and decay accumulator breadth will accept acceptable accumulator accommodation to administer a 1 in 100-year condensate event. Baptize calm in the attainable pit will be directed to the pond, forth with runoff from the processing bulb pad. Inflows to the pond will be pumped to the processing bulb or will be advised and absolved to Wichcika Creek.

The TSF will accommodate acceptable baptize accumulator accommodation to handle the Inflow Architecture Flood based on its dam allocation and cautiously administer added acute events.  A basal TSF begin pond will be maintained, with a committed baptize administration pond afterwards of the baptize accumulator area, as acclaimed aloft which will beforehand a minimum pond aggregate to accommodated account baptize appeal at the processing plant. All antithesis baptize will be pumped to the committed baptize administration adeptness and/or acquaintance baptize ponds at the processing bulb breadth for recirculation in the bulb or to be advised and discharged. A alternation of elimination accumulating stations will additionally be amid forth the afterwards toe of the TSF dam to pump elimination aback into the TSF pond.

Waste bedrock and pit bank baptize affection are accepted to accept animated levels of molybdenum, arsenic, uranium and radium. Baptize in the TSF is accepted to be animated for the aforementioned ambit as decay bedrock and pit bank areas, forth with fluoride. A baptize analysis bulb has been sized based on a account baptize antithesis with the 1 in 25-year anniversary runoff contributions to the decay bedrock areas, attainable pit, and TSF. The bulb is accepted to amusement for molybdenum, arsenic, uranium, radium and fluoride and will be anchored at the processing area. The bulb is sized to amusement up to 2300 gpm of baptize and will acquittal antithesis baptize from the baptize administration accessories to Wichcika Creek.

Long-term baptize affection predictions for the activity breadth will be developed to actuate the continuance of baptize analysis requirements. Closure strategies will be implemented to abate the abiding baptize analysis requirements, including calamity the attainable pit, as able-bodied as resloping and accoutrement of decay bedrock depression and the tailings area.


The TSF is a key aspect of the operation. The afterward operating and abundance activity assumptions were acclimated to actuate the appropriate tailings accumulator capacity:

SRK completed several armpit alternative exercises. Each armpit alternative exercise was based on hardly altered belief provided by the operation and included application of both dewatered (thickened, filtered) and accepted slurry tailings. Accepted slurry tailings auctioning is the abject of the PEA.

The TSF location, blueprint depositional approaches and baptize administration will be added developed to accommodated both bigoted regulations as able-bodied as Canadian and All-around standards of acceptable convenance as the activity advances through the PEA to approaching studies.
