Springfield Project
The Springfield Project comprises a 303km2 ground package located approximately 150km north-east of Meekatharra in the northern Murchison Goldfields region of Western Australia.
The project is located immediately along strike to the east of Sandfire Resources’ DeGrussa Project, where mineral resources now stand at 14.33Mt @ 4.6% Cu and 1.6g/t Au contained in four deposits and mine development is underway.
The strength, size and grade of the DeGrussa Volcanogenic Massive Sulphide (VMS) system support Talisman’s view that the exploration potential in this region and more importantly, immediately within the Company’s Springfield Project – located just 4km to the east of the DeGrussa Deposits – is very high.
“ Talisman has been aggressively exploring the Springfield Project since the grant of the first two project tenements in November 2009, with systematic exploration activities focused initially on the generation of high quality data sets capable of targeting VMS mineral systems.
This data is being used to develop a fully-integrated 3D geological model for the Springfield area with emphasis on identifying stratigraphic, structural and geochemical controls on VMS mineralization and to generate robust targets for drill testing.
Importantly, this systematic and fundamental approach to exploration has now identified what are interpreted to be five specific stratigraphic horizons prospective for the development of VMS mineral systems. The target horizons are typically identified by highly-anomalous copper-gold-zinc geochemistry and associated with extensive epidote-magnetite-hematite alteration.
At a number of prospects (e.g. Homer and Monty) significant copper-iron sulphides (i.e. chalcopyrite-pyrite) have been intersected in drilling, both as widespread disseminations and localised breccia-stringer mineralisation. This style and strength of alteration and the widespread presence of copper-iron sulphides suggests that very active VMS mineralising processes have been in place at the Springfield Project. Work to date has delineated these target horizons over a combined strike length of approximately 35 to 40km.
Exploration activities at Springfield are presently focussed on diamond and reverse circulation drilling, supported by down hole electromagnetic (DHEM) surveys, of specific, discrete targets along these target horizons.
