During the six years that I have been using Leapfrog Mining software, I have found that one of Leapfrog's primary advantages is that its functionality complements that of general mining software packages (GMPs) at each stage of a mining project. For example, I have used Leapfrog to determine the spatial distribution of geometallurgical ore characteristics (ore geochemistry) in order to predict concentrate quality at the scoping-level stage. Drill hole ICP geochemical data was readily interpolated, and integrated with both wireframes and resource block models imported from GMPs. Interpolants of problematic ore geochemistry were quickly coded into the 'informed' block model, which, was easily exported back into the GMP ready for use in preliminary mine planning.
I used Leapfrog software during a property appraisal of an advanced exploration project in the Eastern Goldfields Province, Western Australia. Without access to a resource block model, I used Leapfrog to create 3D isosurfaces of point data without going through the laborious exercise of generating a new block model.
Leapfrog proved to be an effective tool and allowed the user to quickly visualise the 3D geometry of the orebody and generate new exploration targets. The output was easily imported into a standard mining software package and was effectively presented to upper management.
Manual wireframing of the multiple [gold] lode mineralised zone at Saratoga took over a month for our geological staff to model lode envelopes at a single grade cut-off, including geological validation. Leapfrog's 3D mesh processing took just over one hour, with geological validation taking a further two days, thereby dramatically fast-tracking the modeling process. We were then able to consider, not just one, but several contrasting geological scenarios for the purposes of estimating Saratoga's resource.
In the re-assessment of the Cosmo Howley project [in the Northern Territory], a quick method of interrogating the historic assay drill data was required. Rather than follow the normal path of creating a geologically constrained block model, Harmony utilised Leapfrog to acquire seamless grade isosurfaces of the open-pit grade control data and deeper exploration drilling. These isosurfaces were easily imported into the 3D modelling software and immediately emphasised the prominent plunge aspect of the mineralised system.
Apart from the valuable insights into the grade trends, the Leapfrog models were used extensively for presentation purposes as they helped communicate an otherwise complex message.

We used Leapfrog-generated grade wireframes to visualise the broad spatial distribution of gold in the mineralised belt between Fimiston and Mt. Charlotte. The study incorporated all available drill data and allowed visualisation of the gold distribution at a scale that would have been difficult using any other software package. The grade meshes were imported
into Vulcan software and were analysed with other 3D datasets such as geology and structure.
This process highlighted key relationships and consequently assisted with the generation of new near-mine exploration targets. The main benefit of this targeting exercise using Leapfrog was the speed with which the wireframes could be generated using a variety of parameters.

Last year I just had too much work on my plate and I had to farm out a deposit to have it wireframed. That exceeded the cost of Leapfrog and I could have done it with Leapfrog in one day.
If you do a wireframe package, that is one scenario and it can take weeks. If someone walks in and says let's do another scenario for whatever reason - costs changing, the manganese price going through the roof - it throws a big spanner in the works and you have to start again. That's where Leapfrog's scenario effectiveness comes in.
