Mine software solutions

Time is the most important piece of heap leach operations. Understanding how changes in ore and mineral grades, and the timing of ounces to the pad can impact metal recovery. Opencontour mining software includes tools for open pit mine planning, scheduling, and heap leach stacking and recovery to optimize mine performance from mine-to-heap.

Forte Dynamics provides dynamic systems optimization and mine engineering for heap leaching operations. Our unique approach integrates an array of site data from mine-to-heap to enhance and predict metal recovery. Our HLF model uses discretized cells to track metallurgical data, ore amounts and grades, HLP stacking configuration, pad geometry, kinetics, and hydrodynamics to create a matrix to evaluate and enhance mine NPV.


Forte's mine optimization model simulates solution movement and metal extraction as a function of time based on unsaturated solution flow properties, kinetics dissolution and diffusion rates, as well as leaching dynamics. Data for ore crush size, compaction, bulk density, moisture content, solution movement, and leaching time is used to optimize recovery. Short term and long term plans help bring ounces forward and enhance project NPV.

The Forte Analytical team works hand-in-hand with clients to conduct due-diligence reviews of historical metallurgical testing to provide testing plans for current challenges or future needs. Forte Analytical targets testing procedures that focus on first-principle kinetics and diffusion. Results can be used in conjunction with Forte Dynamics' optimization model to generate the highest project value.  


Other Services

Opencontour offers a full-suite of products and services for mining operations. As part of the Forte group, we offer clients additional services to further optimize mine-to-heap systems.


The Forte group - Forte Dynamics (mining and heap leach optimization) and Forte Analytical (metallurgical testing and research laboratory) - consists of skilled engineers, metallurgists, chemists, project managers, drafters, analysts, and mining professionals that offer unique insights that maximize NPV.
