FracOre
Conventional ore reserve estimation relies on geostatistical variograms and
Kriging. These techniques are essentially sophisticated smoothing or contouring
methods, and can only indirectly address key issues of geological structure.
FracOre provides a much more direct approach for estimation of the mineral
resources of vein deposits. Rather than attempting to obtain a volume average,
FracOre directly calculates the volume of minerals based on the thickness and
assay of fractures and veins contained in specific mining profiles. FracOre
works with FracWorks discrete feature network models, which assigns the geometry
and mineral properties of known and extrapolated fractures and veins based on
the FracSys data analysis. As a result, FracOre is able to directly incorporate
the full range of field data from boreholes, geology, geophysics, and assay
data.
FracOre is a Windows95 and Windows NT 32-bit graphical application. The primary
inputs to FracOre are FracWorks discrete feature network models and a geometric
object defined as a tunnel layout or convex hull outline.
