Improved Resource Estimation

Maptek Vulcan™ was applied to geological modelling and resource estimation to help increase grade tonnage for the Wigu Hill property in Tanzania.

In early 2012 Montero Mining and Exploration Ltd contacted Maptek to conduct resource estimation work for their Wigu Hill property in Tanzania. Montero needed a detailed study of the project to increase the resource.

Maptek provided Montero with an improved constrained resource block model, a grade and tonnage report, and a CSV resource block model compatible with mine planning software. This gave Montero the information they needed for mine design and optimisation, and to create a base scenario schedule to move the project forward.

Maptek worked with drillhole and trench data provided in Microsoft Access® databases. A geological model was built and a resource was calculated using grade estimation tools in Vulcan.

The estimation work was done within the final Vulcan model with user defined estimation parameters.
