Name: St Ives gold-mine.
Location: Located 55 km south of Kalgoorlie, Western Australia.
Brief description: St Ives takes its name from the largest of many small, historic workings scattered throughout the area, that of Ives Reward, which was discovered by prospector Pat Ives in 1919.
Brief history: Gold Fields bought St Ives in December of 2001 for $233-million – $180-million in cash from WMC Resources, as well as $53-million in Gold Fields shares.
Mining method: Underground and opencast mining.
Reserves: The total underground and surface proved andprobable reserves amount to 22,9-million tons in the 2004financial year.
Resources: The total opencut and underground measured,indicated and inferred resources amount to 89,9-million tons in the 2004 financial year.
Geology: The deposits are situated in the north-west trending Norseman-Wiluna Greenstone Belt and were formed in the Archaean era, about 2 600-million years ago. The deposits are located on secondary structures that splay off the regionally-dominant Boulder-Lefroy Fault. The secondary structures include quartz vein arrays, breccia zones, mylonites and ultra-cataclasites that are often linked to form complex anastomosing lodesystems.
Major infrastructure and equipment: Three underground mines (Junction, Argo and Leviathan), two opencast complexes (Greater Revenge and Argo), a carbon-in-pulp plant and heap-leachfacility.
Future prospects: With completion of the new mill making up $41-million, approximately $25-million planned for exploration, and leaving sustaining development capital at $46-million, largely for underground development and pit stripping, the total planned capital expenditure for the 2005 financial year is estimated at $112-million.
