Dordie North prospect; Dordie Rocks North


Located 11 kilometres south-east of Widgiemooltha.

"Eardleyite" (otherwise known as Takovite) occurs here in serpentinite as narrow fracture filling, and thin surface coatings. It is associated with glaukosphaerite, nickeloan magnesite, nickeloan glauconite, atacamite, paratacamite, malachite, azurite, chalcopyrite and lithiophorite.

Glaukosphaerite is intergrown with nickeloan celadonite in veinlets of goethite-quartz-tremolite rock.

The prospect was discovered in 1967 by Anaconda and CRA.

The ultramafic formation dips 45 degrees east, 300 metres thick, of picritic to peridotitic flow units, with increasing thickness with depth. It consists of talc, tremolite, chlorite rock, minor carbonate and serpentine. Thin phlogopite-rich zones and chlorite are abundant, with quartz-feldspar porphyry dykes. The footwall is amphibolite.

There are two shoots, named A and B. A is larger at a length of 600 metres on the surface. It occupies an embayment at the ultramafic-footwall contact, plunging gently south, although the dip steepens with depth.

The mineralised zone is up to 10 metres thick, but commonly 1–2 metres. Low grade disseminated ore of narrow veins, matrix to massive sulphide at or near the basal contact.

The B shoot is 60 metres long, at 200 metres above A shoot, 2–4 metres thick, with a grade lower than A.

Primary mineralisation is pyrrhotite, pentlandite, minor chalcopyrite, gersdorffite, magnetite, chromite, and bismuthinite.
