An oriented ellipsoid search was applied to select composites for interpolation, with orientations derived from variogram models. Gold grade estimation was completed using a three-pass search strategy ...

An oriented ellipsoid search was applied to select composites for interpolation, with orientations derived from variogram models.

The relationship between madogram (Euclidean) and the square root of the variogram will be used as verification procedure. Equation 1 presents this relationship whose result must approximate the ...
