EnviroGold Global Achieves Major Process Optimisation Breakthrough, Doubling Project Economics and Enhancing Environmental Performance
EnviroGold Global (ESGLF) has announced a significant breakthrough in its mine waste processing technology, achieving an 87% gold recovery and 78% recovery of other targeted metals into 27.8% of the initial mass through pre-concentration test work for a US client. The company's optimized process has led to a doubling of project NPV10 and internal rate of return.
The enhancement allows for a 70% reduction in leach plant scale while maintaining the one million tonnes per annum throughput capacity, resulting in significant CAPEX and OPEX savings. The process improvements also deliver environmental benefits by reducing Net Acid Producing Potential in waste streams. EnviroGold has partnered with ANDRITZ to simulate the NVRO Process using IDEAS Simulation software to further optimize client-specific processing.
EnviroGold Global (ESGLF) ha annunciato un importante progresso nella sua tecnologia di trattamento dei rifiuti minerari, ottenendo un recupero dell'87% dell'oro e un recupero del 78% di altri metalli mirati su un 27,8% della massa iniziale attraverso lavori di pre-concentrazione per un cliente negli Stati Uniti. Il processo ottimizzato dall'azienda ha comportato un aumento della NPV10 del progetto e del tasso interno di rendimento.
Questo miglioramento consente una riduzione del 70% della scala dell'impianto di lisciviazione mantenendo la capacità di trattamento di un milione di tonnellate all'anno, con conseguenti significativi risparmi di CAPEX e OPEX. Inoltre, i miglioramenti del processo offrono benefici ambientali riducendo il Potenziale di Produzione di Acidi Netto nelle correnti di rifiuto. EnviroGold ha collaborato con ANDRITZ per simulare il Processo NVRO utilizzando il software di simulazione IDEAS per ottimizzare ulteriormente il trattamento specifico per il cliente.
EnviroGold Global (ESGLF) ha anunciado un avance significativo en su tecnología de procesamiento de residuos mineros, logrando un recupero del 87% de oro y un recupero del 78% de otros metales específicos sobre un 27,8% de la masa inicial a través de pruebas de pre-concentración para un cliente en EE. UU. El proceso optimizado de la empresa ha llevado a un duplicado del NPV10 del proyecto y de la tasa interna de retorno.
Esta mejora permite una reducción del 70% en la escala de la planta de lixiviación mientras se mantiene la capacidad de procesamiento de un millón de toneladas anuales, lo que resulta en ahorros significativos en CAPEX y OPEX. Además, las mejoras en el proceso también proporcionan beneficios ambientales al reducir el Potencial de Producción Ácida Neto en las corrientes de desechos. EnviroGold ha formado una alianza con ANDRITZ para simular el Proceso NVRO utilizando el software de simulación IDEAS para optimizar aún más el procesamiento específico para el cliente.

EnviroGold Global (ESGLF) hat einen bedeutenden Durchbruch in seiner Technologie zur Verarbeitung von Bergbauabfällen angekündigt und erzielt eine Goldrückgewinnung von 87% sowie eine Rückgewinnung von 78% anderer gezielter Metalle über 27,8% der ursprünglichen Masse durch Vorkonzentrationstestarbeiten für einen US-Kunden. Der optimierte Prozess des Unternehmens hat zu einer Verdopplung des NPV10 des Projekts und der internen Rendite geführt.
Die Verbesserung ermöglicht eine Reduzierung der Größe der Laugungsanlage um 70%, während die Verarbeitungs-Kapazität von einer Million Tonnen pro Jahr aufrechterhalten bleibt, was zu erheblichen Einsparungen bei CAPEX und OPEX führt. Darüber hinaus bringen die Prozessverbesserungen auch Umweltvorteile, indem sie das Netto-Säureproduktionspotenzial in Abfallströmen reduzieren. EnviroGold hat mit ANDRITZ zusammengearbeitet, um den NVRO-Prozess mit der IDEAS-Simulationssoftware zu simulieren und die kundenspezifische Verarbeitung weiter zu optimieren.

TORONTO, Feb. 04, 2025 (GLOBE NEWSWIRE) -- EnviroGold Global Limited (CSE: NVRO | OTCQB: ESGLF | FSE: YGK) (“EnviroGold,” or the “Company”), a clean technology company that monetises mine waste and tailings while reducing environmental and social liabilities, has doubled project NPV10 and internal rate of return following process optimisation and pre-concentration test work for a US based client. The pre-concentration achieved
Key Technical Outcomes:
- Pre-Concentration Efficiency: Achieved
87% gold recovery and78% recovery of other targeted metals into27.8% of the initial mass. - Reduced Plant Scale: The tailings volume throughput remains at nameplate capacity of one million tonnes per annum, with only
30% of the feedstock volume requiring leaching in the NVRO Process following pre-concentration. - Reduced CAPEX and OPEX: A
70% reduction in leach plant scale leads to significant CAPEX and OPEX savings. - Economic Impact: After factoring in additional equipment and associated operational costs, preliminary financial modelling indicates at least a twofold increase in project NPV₁₀ and internal rate of return.
- Environmental Benefit: By targeting sulphide recovery in pre-concentration and directing a high acid-neutralising component to waste, Net Acid Producing Potential (NAPP) in waste has been significantly reduced without additional neutralisation steps. The NVRO Process further consumes sulphides in its reaction pathway, leading to a substantial reduction in NAPP within NVRO Process waste streams.
- Process Optimisation: To further enhance project economics for clients, EnviroGold has engaged international technology Group ANDRITZ to simulate the NVRO Process using the industry leading IDEAS Simulation software. Learn more about IDEAS at www.andritz.com. This simulation will accelerate client specific process optimization, engineering, and right-sizing for end-to-end processing of sulphidic mine tailings.
- These developments further strengthen EnviroGold’s first mover advantage and accelerate the commercialisation of its highly efficient and scalable solution for processing mine tailings.
CEO, David Cam, commented: “In addition to the demonstrated outcomes of the NVRO Process, incorporating pre-concentration methodologies delivers significant economic, operational and environmental enhancements to our technology. The addition of the Andritz simulation software, combined with our ability to fast-track test work and feasibility studies through the EnviroGold Demonstration Plant, places the company in a stronger position to accelerate its commercialisation strategy.”
