Better Data.Better Decisions.

Minpraxis generates high-resolution engineering data from drill core, giving mining teams a more detailed understanding of rock properties and variability.

Choose from geotechnical or geometallurgical data packages, or build a testing program around the specific requirements of your project.

Continuous data

Every Metre Measured

Minpraxis fills the gaps by measuring strength, hardness and density continuously along the full length of core tested.

Informed mine design

Geotechnical Data

The challenge

Geotechnical models are fundamental to mine design, but conventional testing typically relies on selectively chosen samples, leaving significant gaps in the understanding of rock strength and variability.

What Minpraxis adds

Minpraxis generates high-resolution strength measurements along the drill core, capturing changes associated with veining, alteration and lithology, including weaker zones that may be missed by traditional test programs.

Geometallurgical Data

The challenge

The crushing and grinding characteristics of an orebody can vary significantly across a deposit. Without enough data, that variability can be missed in mill design and production planning.

What Minpraxis adds

Minpraxis generates high-resolution comminution data from resource core, increasing the spatial coverage of information available for orebody modelling and helping teams better understand how processing behaviour changes throughout the deposit.

Informed resource models

Density Data

The challenge

Density converts volume to tonnage in every resource model, and it varies with lithology, alteration and mineralization.

What Minpraxis adds

Minpraxis measures density on every piece of half-core tested using measured mass and volume. The result is a continuous density record along the hole, from the same core used for strength and comminution data.
