14.3.4.13 Model Validation
Results of block modeling were reviewed in three dimensions and compared on a section by
section basis with corresponding manually interpreted sections prepared prior to model
development. This showed block model grade patterns within the sulphide zone to generally
conform to a near-vertical east-west striking deposit system with a moderate westerly grade
plunge (Figure 14.21). This is consistent with the recognized east-west normal fault
controlled systems of the Pulacayo dome complex, locally represented as stock work, narrow
vein and associated disseminations in the overlying volcanic rocks and high grade vein style
mineralization of intruded sedimentary rocks.

Oxide zone silver grade distribution showed discrete zones of mineralization that have good
correlation with higher grade mineralization within the underlying sulphide zone (Figure
14.22). Overall, results of the visual inspection of both the sulphide and oxide zones for all
