01TAILINGS
Metal that remained in tailings.
Mining tailings may contain metal not recovered by the original processing. The assessment starts with material characterization and measurement of its variability.
Technology to expand
the use of
mineral resources.
Green Mining develops projects focused on recovering metals from tailings and low-grade mineral resources. Its approach combines mineralogical characterization, processing route definition and evaluation of the technical and economic conditions of each project.

Applications
Where the technology applies.
Green Mining evaluates metal recovery opportunities in two types of asset, on the same technology base.
02LOW GRADE
Low-grade resources.
Whether a lower-grade deposit can be developed depends on the whole picture: material, scale, recovery, infrastructure, costs and commercial conditions. Green Mining evaluates that potential project by project.
03SCALE
Plants in modules.
Each module is a compact plant. Capacity is sized to the asset, with several modules running in parallel when the project warrants it.
Technology
A proprietary four-layer architecture.
Four integrated layers, with real-time algorithmic process control since 2012.
The route combines compact-column flotation, liberation of occluded metals, selective chemistry and real-time process control. Each project's configuration is defined from the material characterization; on the gold route, the process does not use cyanide.

Environmental responsibility
Environmental objectives, evaluated per project.
Use of material already deposited.
In tailings projects, the goal is to use material already extracted and deposited. The effect on the liability depends on characterization and on management of the remaining residue.
Managing the remaining residue.
All processing generates residue. Its disposal and monitoring are part of the project and of the required environmental studies.
Cyanide-free gold.
On the gold route, the process does not use cyanide. This does not remove other impacts, which are assessed in each licensing process.
Studies and permits per project.
Each project follows local regulation, with its own environmental studies and licensing, including on low-grade deposits.
Signature line
Recovering metal and managing residues,
responsibly, project by project.
Model
How Green Mining enters.
Green Mining doesn't sell equipment: it structures and operates projects with the asset owner, in stages, with a decision at the end of each phase.
Preliminary screening
Basic asset characterization: location, type, estimated volume, commodity, history. Feasibility assessment in a short window.
Technical assessment
Sampling and material characterization at a Green Mining lab or validated partner. Per-metal recovery simulation.
Pilot
Field-scale test, confirmation of operational and commercial parameters.
Modular deployment
Partnership format negotiation: acquisition, joint venture, royalty, or operation under contract. Installation of modules in parallel, sized to the asset.
Possible formats
Acquisition · Joint venture · Royalty · Operation under contract , defined case by case.
