solid model domains were limited up-dip by the topographic surface or half the distance to a
constraining drill hole and were limited by either a down-dip extension of 25 m from the last
intercept, half the distance to a constraining drill hole, or to a depth that was continuous with
the depth of the domain defined on adjacent sections. Along strike, the solid models were
projected 25 m from the last defined section that showed continuity and definition based on
the current drill hole database, or half the distance to a constraining drill hole. For silver, lead,
and zinc, nine domain solid models defining zones of veining and higher grade mineralization
were created. The 27 resulting metal domain solid models range from a few meters to tens of
meters in thickness and have varying continuity over a 1,500 m strike length oriented along
Az. 280°. All occur within a 600 m sub-vertical dip extent (Figure 14.3, Figure 14.4 and Figure
14.5).
A peripheral constraining wireframe enveloping all the metal domains was developed for the
purpose of interpolating grade for each metal outside the respective metal domain solid
models. Limits of the peripheral constraint were defined by the limits of the domain solid
models and presence/absence of sampling results.
