recovery technologies.

EnviroMetal Technologies Inc. is developing and commercializing economic and environmentally sustainable metal recovery technologies for applications in the gold mining industry. EnviroMetal extracts precious metals from ores, and concentrates by deploying its proprietary non-cyanide, water-based and neutral pH treatment process.


Our Mission
To lower the environmental impact of gold mining. To help our partners by providing an environmentally sustainable and financially competitive alternative to the extensive use of smelting, cyanide and mercury in gold mining.

Our unique and environmentally friendly technology

EnviroMetal’s proprietary and patented chemistry technology extracts precious metals from conventional mine products including gravity, flotation and pre-treated refractory concentrates.

Our technology solution is a cost-effective and environmentally sustainable alternative to the use of cyanide and smelters for the recovery of gold.

Technology Overview

The gold mining industry faces monumental challenges to balance economics with environmental impact.

EnviroMetal has the solution…

“The EnviroMetal Process”
offers miners:

  • A cost competitive, on-site gold recovery alternative to smelting.
  • An environmentally sustainable gold recovery alternative to cyanidation and reduce overall impact of gold mining.
  • Improved stakeholder and regulatory support for gold mining.
  • Opportunity to unlock gold mining projects in environmentally sensitive locations.

Envirometal is led by a first-class staff of scientists and engineers. Our extensive expertise in metals recovery and hydrometallurgy positions us with a unique knowledge set applicable to our target markets.

Our Technology Readiness

Gold Mining

The EnviroMetal Process has consistently demonstrated broad application through lab scale and bulk sample pilot test programs both on-site and at the Company’s pilot plant located in Metro Vancouver. The technology is ready for in-field pilot testing with a Technology Readiness Level (“TRL”) of 7.

Pipeline Applications

In Situ Gold Recovery (ISR)

EnviroMetal has the potential to change the way the world extracts gold. With its partner Group 11 Technologies, EnviroMetal will be testing the potential for in-situ (or in-place) leaching of gold which would reduce the impact of gold mining around the globe. It offers the ability to extract gold without moving material or setting up conventional gold mills. EnviroMetal’s patented gold recovery chemistry and process applications make this opportunity possible.

Technological advantages

EnviroMetal has developed the most significant innovation in gold recovery since the introduction of cyanide in 150 years ago. The technology has been independently verified and has been rigorously tested on multiple concentrate materials.


Simple chemistry solution operates at ambient temperature and pressure.


Proprietary and patented core technology.


Low environmental footprint – produces no toxic air emissions or wastewater.


Efficient – excellent leach kinetics and recoveries.
