Summary:

The Daisy Mining Centre lies along the Bulong Anticline within the Gindalbie Terrane of the Norseman-Wiluna Greenstone Belt. The core of the Bulong Anticline (the Yindarlgooda Dome) contains mineralised granitic intrusive rocks in a sequence of felsic to intermediate conglomeratic sedimentary rock, structurally overlain by a mafic-ultramafic succession. Quartz-feldspar porphyry dykes and sills intrude the sequence.

A northwest striking (50°), south dipping shear (the Godard Shear) separates the ultramafic sequence to the south from the felsic volcaniclastic rocks to the north. The structural setting of the Daisy Complex is analogous to that of the Kanowna gold mining centre, with is located on shears spaying away for the regional Kanowna Shear.

The Daisy Complex comprises intermediate to felsic volcanic rocks. The mineral deposits are located east and beneath an overlying north-northwest trending ultramafic unit of approximately 250 m thickness, comprising mostly variably serpentinised peridotites with localised talc alteration.

The entire sequence is intruded by two quartz-feldspar porphyritic units. One group (the footwall cross-cutting porphyries) are oriented northwest and dip at 45°–60° west, while the other set (Main porphyries) are oriented north–south and are vertical to steeply east dipping. There are also numerous east–west trending Proterozoic mafic dolerite intrusive dykes, ranging from a few centimetres to several metres thick, distributed throughout the deposit area.

Mineralisation occurs along north–south trending, transpressional structures, commonly along or associate with the Main porphyry contacts and/or north–south shear structures. Haloes of sericitepyrite-fuchsite alteration around mineralised quartz carbonate veins typically highlight metal-rich fluid pathways. Galena and sphalerite are generally enriched in typical Daisy ore veins and compressional shear structures on vein margins are also excellent indicators of gold mineralisation.

Mineralised veins are typically subvertical, vary between 0.05 m and 1 m in width, generally trend north–south and exhibit significant wall rock alteration. Milky white (bucky), often wide (>2 m) nonmineralised veins trend east–west, have significant alteration halos and cross-cut ore mineralisation.

Mineralisation is not bound to one lithology or structural type at the Daisy Complex. Observations highlight that gold mineralisation has occurred along a north–south series of planes and that fluids have used favourably oriented structures during migration. Deposition appears to be structurally controlled; however, some chemical deposition may have occurred near the overlying ultramafic unit.
