Golden Grove and other Base Metal Deposits
We work with our clients to develop modelling vectors from Structural mapping and Isometric mapping to develop realistic geological solutions to help understand the alteration mineralogical distribution in 3-D for focussed targeting.
3-Dimensional (3-D) Exploration Geological Models represent the spatial distribution of economic geology under the ground and are used within the Minerals Industry to explore Australia’s vast undercover Mineral’s Wealth. The greatest risk to the Australian Mineral’s Industry is in the poorly understood, 3-D distribution of the sub-surface geology. Mining Business Development Strategies require a thorough understanding of the economic geology within a district in order to develop a sustained, long-term mining outlook and implementation of practices. Yet the majority of geoscience data available to the modern day explorer is limited to the 2-Dimensional (2-D) space.
Consider Golden Grove in Western Australia. The deposit is hosted within a high-strain mobile zone that displays complex and tight refolding along strike. While significant folding and fabric forming events have taken place, the primary metal and alteration zonations are still identifiable and are able to produce a ‘way up’. The deposit is an overturned, folded and sheared VMS. While the rocks surrounding the deposit have taken up considerable strain, the remobilised mineralisation behaves within it's structural frame of reference. Any graben's or early syn-deposit related features - are now completely transposed reflected by the structural fabrics readily observed across the district.
When it comes to making a 3-D model, it is important that we draw our knowledge from the available sources of outcrop either underground or from the pit in order to constrain our modelling. Simply plugging data into a software package and hitting the RUN button does not yield realistic or even reasonable 3-D models.
