Just south of Urunga lies the Newry State Forest, here there were formerly several Antimony mines and prospects. Nearby, on the opposite side (Eastern) of the Pacific Highway there is a small track along which the 66kV power line runs. There was at one time a road sign naming this track as Antimony Trail. I have explored this track with the land-owners permission and found large blocks of quartz containing metallic mineralisation. The owners took me to a site nearby where there is a large level cleared patch that has the appearance of a possible rehabilitated mine site. The owners are new to the area and the neighbours are also not of long standing and do not know the history of the site. When I tested the mineral (with almost the appearance of molybdenite) using the charcoal block assay and the hot concentrated sulfuric acid test, the results showed the presence of tellurium and bismuth. Further study of the rock shows the presence of Pyrite, Chalcopyrite and possibly Bismuthinite (silver white,pale yellowish tarnish, soft and marks paper) with oxidation products that appear to be an iron tellurite and Bismutite. Some of the chalcopyrite is coated with a greenish-white material that looks unlike Malachite and which I have not yet tested (only small amounts). I would welcome comment.
(Ross Pogson has a sample and may be able to confirm or refute my identification)
Ross has recently (Early March 2015) reported that X-ray examination of the specimen I gave to him shows it to be molybdenite. I have re-tested material that I have and found that molybdenite is present and constitutes the small rosettes distributed through the white quartz phase. The larger groups associated with chalcopyrite and pale powdery material once again gave the above tests for tellurium. I will ask Ross to X-ray test some of this selected material when next I see him.
