Empire Mine & Dredge

Rethinking mineral extraction.

Empire Mine & Dredge is developing a proprietary approach to subsurface mineral extraction, designed to access, mobilize and recover valuable mineral-bearing material without the conventional requirement to first remove large volumes of overburden.

First commercial application
Nome, Alaska

Moving value. Not the earth.

The problem

What if you didn’t have to remove all the worthless material to reach the valuable material?

Conventional extraction can require substantial excavation, material movement, storage and remediation simply to access the target resource.

Empire’s methodology is designed to extract target material located at depth to the surface without removal of overburden, saving significant time, cost and energy.

How it works

A different approach

Four stages, delivered as one integrated platform.

  • 01

    Penetrate / Position

    Deploy the Vibropump to the target depth.

  • 02

    Extract

    Draw the mineral-bearing material to the surface.

  • 03

    Process

    Separation and recovery on board.

  • 04

    Repeat

    Extract and reposition the Vibropump, and repeat.

Progress

MVP complete, production Vibropump in development

Empire’s strategy is to move from engineering development through physical testing and towards commercial application.

First commercial application

Nome, Alaska

Nome is intended to provide both a route to mineral production and a real-world environment in which Empire’s technology can be commercially evaluated.

Nome is intended to be the first commercial deployment, not the limit of the opportunity.

Applications

One technology. Multiple possibilities.

Empire is commercializing an extraction methodology, not a single-purpose machine.

  • Mineral extraction

    Targeted recovery of subsurface mineral-bearing material, making the uneconomical economical again.

  • Marine and offshore

    Where water depth, overburden and extraction limitations challenge conventional methods.

  • Difficult material

    Compacted or difficult-to-handle material, and increased flow density of up to 40%+ solids by weight.

  • Environmental and specialist

    Targeted subsurface removal of contaminants, or injection of treatment options to improve in-situ treatment outcomes.
