NTH:CC - Nord Precious Metals Advances Re-2Ox Pilot Plant Process Equipment Selection with SGS Bench-Scale Metallurgical Test Programme
(TheNewswire)
July 29, 2025 – TheNewswire - Nord Precious Metals Mining Inc. (TSX.V: NTH)(OTCQB: CCWOF) (FRANKFURT: 4T9B) (the "Company" or"Nord") reports that SGS Canada Inc. (Lakefield) hasoutlined a two-phase bench-scale metallurgical test programme designedto translate the Re?2Ox flowsheet into a pilot-ready design withtechnical parameters for scale-up. The Re-2Ox process targets therecovery of critical and precious metals from concentratescontaining elevated deleterious metal levels that typically incurprocessing penalties or rejection at conventional processing andrefining facilities.
Highlights
Hard-rock concentratevalidation -- Alkaline pressure-leach tests willdefine the operating window for the Company's hard-rock concentratesamples. A confirmatory test on legacy tailings preserves futurereclamation optionality.
Equipment specifications for modulardeployment -- SGS will generate kineticinformation, mass balances, and reagent consumptions supportingcontainerized unit designs that can be deployed at mine sitesglobally.
Offtaker flexibility -- Process liquors will be retained to enable precipitationand calcination tests for cobalt oxide or carbonate production ifstrategic partners require alternatives to sulfate-based batterymetals, eliminating the need to repeat primary leaching.
Technical Programme Structure
Phase 1 will establish operating parameters throughsystematic bench testing across the complete Re-2Ox flowsheet. Thealkaline pressure leach testing will evaluate the Company'sconcentrate samples to establish optimal processing parameters. Theprogramme will test Nord's concentrate samples to develop processingsolutions for complex feeds. Nord's samples include materials withdeleterious content that would typically face significant smelterpenalties, demonstrating the Re-2Ox process's ability to handlechallenging feed compositions.
Phase 2 will process a single autoclave batch througheach downstream circuit, validating continuous operation at pre-pilotscale. Caustic regeneration testing addresses reagent recycling, acritical factor for remote deployments where chemical logistics poseoperational challenges.
MarketContext
The closure of major, deleterious metal-tolerantsmelters, including Tsumeb's recent move to care and maintenance, hascreated an acute processing bottleneck for complex concentratesglobally. Nord's modular Re?2Ox technology targets this gap,offering field-deployable solutions that convert penalty-bearing feedsinto saleable products at the mine gate.
The SGS bench-scale data will support Nord'sprogression toward Technology Readiness Level 7, positioning Re?2Oxfor commercial licensing following the MICA-funded pilot demonstrationat Temiskaming Testing Labs.
"This programme converts laboratory insight intopurchase-order detail," said Frank J. Basa, B.Eng., ChiefExecutive Officer. "The ability to process deleterious metalconcentrate feeds that conventional smeltersreject represents a significant commercial opportunity as global oregrades decline and impurity levels rise."
CommercialImplications
The bench-scale data will support:
Modular unit specifications for deployments
Capital cost estimates enablingbuild-own-operate-transfer agreements
Technical data supporting penalty element removaltargets exceeding 99%
Product specifications adaptable to marketrequirements, whether battery-grade sulfates, oxides, orcarbonates
Next Steps
Phase 1 data will allow SGS to produce equipment listsand obtain supplier quotations, narrowing the capital?cost estimatefor the planned one?tonne?per?day Re?2Ox pilot line atTemiskaming Testing Labs. The Company intends to finance Phase 1 fromexisting resources, complemented by the previously announced C$200,000MICA grant.
SGS will issue a formal proposal incorporating theabove scope, deliverables, and a detailed schedule. Upon execution,selection work is expected to commence. An interim design?basismemorandum will be released mid?programme, followed by acomprehensive report that will support pilot procurement, financing,and strategic partnership discussions.

About Nord Precious Metals MiningInc.
Nord Precious Metals Mining Inc. operates the onlypermitted high-grade milling facility in the historic Cobalt Camp ofOntario, where the Company has established a unique positionintegrating high-grade silver discovery with strategic metals recoveryoperations. The Company's flagship Castle property encompasses 63 sq.km of exploration ground and the past-producing Castle Mine,complemented by the Castle East discovery where drilling hasdelineated 7.56 million ounces of silver in Inferredresources grading an average of 8,582g/t Ag (250.2 oz/ton) in 27,400 tonnes of material from two sections(1A and 1B) of the Castle East Robinson Zone, beginning at a verticaldepth of approximately 400 meters. Note that mineral resources thatare not mineral reserves and do not have demonstrated economicviability. Please refer to the Nord Precious Metals PressRelease May 28, 2020, for theresource estimate.
Nord's integrated processing strategy leverages thesynergistic value of multiple metals. High-grade silver recoverysupports the economics of extracting critical minerals includingcobalt, nickel, and other battery metals, while the company'sproprietary Re-2Ox hydrometallurgical process enables production oftechnical-grade cobalt sulphate and nickel-manganese-cobalt (NMC)formulations. This multi-metal approach,combined with established infrastructure including TTL Laboratoriesand underground mine access, positions Nord to capitalize on bothprecious metals markets and the growing demand for batterymaterials.
The Company maintains a strategic portfolio of batterymetals properties in Northern Quebec through its 35% ownership inConiagas Battery Metals Inc. (TSXV: COS) as well as the St.Denis-Sangster lithium project comprising 260 square kilometers ofprospective ground near Cochrane, Ontario.
