This approach allows you to objectively assess and minimize the risks associated with geological uncertainty. After updating the block model and ore / overburden contacts in GEOVIA Surpac, the geologist loads this information with the click of a button into the VIST ASD system, after which the data is available to all users in both systems.
#Surpac overburden software
In addition, the database was audited using Surpac software no overlapping. When designing and evaluating new deposits under conditions of low exploration, our specialists try to cover all the existing uncertainties and make calculations not only based on the expected (most likely) version of the model, but also taking into account the entire range of possible variants of the geological structure. These casings extend through the overburden into the bedrock so that it is.
It is reported at a Net Smelter Return (NSR. The mineral resource estimate is pit-constrained with a bedrock slope angle of 45° and an overburden slope angle of 30°. When designing the development of new fields, as well as changing design solutions for already developed deposits, three-dimensional models allow you to perform multivariate calculations for various scenarios of field development. The resource estimate was completed using GEOVIA Surpac 2021 using a sub-block model at a parent block matrix of 5m x 5m x 5m (minimum block size of 1.25m x 1.25m x1.25m).
