A New Geological Model for the Globe Progress Mine, New Zealand

Gold mineralisation at the Globe Progress deposit is hosted by a geologically complex zone of shearing and brecciation, within a package of deformed metasediments. Mineralisation styles range from quartz breccias and lodes to sheared clay pug zones and disseminated sulfides._x000D_
A review of the diamond drill core intersections through the deposit indicates that critical hanging wall and footwall contacts can be a combination of sharp or gradational; visual or non-visual boundaries. Approximately 60 per cent of mineralised contacts can be confidently identified visually, particularly where associated with veining, distinct brecciation or shearing, and high sulfide content. However, the gold grade and distribution of disseminated mineralisation can be extremely difficult to estimate visually, with implications for resource estimation and grade control when mining._x000D_
Using observed drill hole geology and assays, a new geologically based model for the gold mineralisation has been constructed for the deposit to reflect the expected variability of the mineralisation contacts. This new model will constrain resource estimation and also serve to act as a predictive model when open pit mining commences. Nevertheless, careful grade control practices such as drilling, trenching and supervised extraction of ore will be required to maximise ore recovery and minimise dilution during open cut mining._x000D_
