I have computed and modeled variograms for four (4) drill hole densities and performed Sequential Gaussian Simulation (SGS) for two block volumes using the SGeMS software. Subsequently, the aim is to quantify the error with corresponding confidence level associated with the two block volumes to assess the financial implications. How would one calculate the error for a monthly/quarterly/annual production with 90% confidence limit using the SGeMS software?

Ps. The block volumes considered are 100x100x15 and 100x100x45m
