The Optiro Resource Estimation package is a suite of software tools that help geologists create better resource estimates:
- with greater accuracy and consistency
- more efficiently
- with improved transparency and auditability
With more than twenty years’ experience using Surpac on mine sites around the world, our highly skilled mining consultants have developed tools to improve the capabilities and efficiency of resource geologists on site and in the office.
Our products work seamlessly with Surpac and are designed to streamline workflows and offer new functionality which is either currently unavailable or cumbersome to perform.
OREpack products include tools which can help you optimise kriging parameters, manage the multitude of estimation parameters for multiple elements in multiple domains for resource and grade control models, create accurate global and local estimates of recoverable resources at SMU scale from sparse drilling data, optimise drill pattern spacing, and validate block models.
|OREpack™ Products||How the product will make your life simpler|
|Kriging Neighbourhood Analysis||Enables you to optimise kriging parameters such as block size, number of samples, maximum search distance, and number of discretisation points.|
|Global Change of Support||Provides an accurate estimate of global recoverable resources. It has been said that “all models are wrong; some are useful”. Any resource-scale model created by kriging or other linear estimation technique will struggle to accurately represent the tonnes and grade mined at the Selective Mining Unit (SMU) scale. The Global Change of Support module can produce a global “change of support” to modify the grade tonnage curve of any existing block model into one which represents mining at SMU scale. This is especially valuable during the feasibility or prefeasibility stage of any project.|
|Local Uniform Conditioning (LUC)||Is an estimation technique which produces accurate estimates of SMU blocks from widely spaced drill data without “over smoothing”. LUC models are particularly useful to mining engineers who need as much resolution as possible during mine optimisation and long term mine planning. OREpack’s LUC module is one of the first local uniform conditioning products on the market, and is by far the simplest to use. All that you need are the normal parameters that you would put into any ordinary kriged estimation.|
|OREpack Grade Control System||Is a customised solution which will enable even the newest staff on your team to perform all the complex operations required during grade control quickly and efficiently.|
|Drillhole Spacing Optimiser||Uses KNA to help you select the optimal drill pattern spacing and sampling increments. This can be used in to determine resource-wide infill drilling spacing, as well as grade control patterns.|
|Surpac Estimation Manager||Enables you to easily handle the hundreds of parameters and files required during the estimation of a multi-domain, multi-element resource.|
|Declus Optimiser||Is a vital part of any block model validation. Declustering weights need to be incorporated when comparing drillhole sample grades against block model grades – both on a domain basis, and in swath (longitudinal plots). This handy tool helps you select the optimal declustering cell size, and also assign declustering weights to individual samples.|
