Hi all
There was an extended field trip held in June 1993 to the Plumbago Station area in South Australia, presumably after the Joint Mineralogical Societies Seminar. Is there anyone that knows what localities were visited on Day 1? One was a copper deposit. I have a specimen collected that day that is labelled as "West Plumbago". It appears to be small groups of acicular malachite on chrysocolla.

Hi Steve,
Yes it was a post seminar field trip, with the part to the Olary
region led by Ian Plimer, followed by a trip to Mt Lyndhurst station
led by Geoff Randall. It was a great trip with plenty of collecting
opportunities.
John Bosworth presented a report in the Victorian Min Soc Newsletters
104 & 105 which I will separately e-mail.

Steve, just saw the picture, I suspect it may be cornwallite rather than malachite, looks like Ethiudna material. Very nice!

If it is the same field trip I am thinking of, I believe it was lead by Vince Peisley, be worth dropping him a line
Cheers

Hi Steve
It may not be identical to yours, on a closer look (yours could be one of the mixite group?). I went to do a close up photograph of my specimen, then thought i should firstly do an XRD to confirm what the green mineral is. It looks like something in the olivenite-libethenite series - needs a bit more work though. I dont think enough has been done on this deposit!

An update Steve -its a pretty good match for zincolibethenite, but I will need to check the chemistry on the SEM (but your specimen may be different still!)

Steve, did you decide on the location?
There are three easily accessible copper mines on Plumbago that may
have been visited during your field trip.
The Ethiudna mine (GE - 32.02.58S, 139.50.15E) is close to the road to
Croker Well and 5 km northwest of the homestead. There are two main
shafts, one at the top of a small hill with a large dozer scrape
nearby to the dumps. Very odd combination of minerals from this spot.
The other shaft - Pipers shaft - is about 450 metres to the South and
has a small open cut (GE - 32.03.13S, 139.50.15E) with lots of
chrysocolla in the dumps. Nearby is Stremples shaft at 1.5 km to the
southwest from Pipers and is famous for sprays of clinoclase.
The second mine is the Mount Victoria Copper Mine which is reached
through a small valley on the western side of Mount Victoria about 11
km north of the homestead (GE - 31.58.36S, 139.50.08E).
The last mine is the Billeroo Copper Mine, which is north of Billeroo
hut on the western side of the range and is reached via a track that
passes the hut then swings west through a saddle (GE - 31.53.28S,
139.55.54E) around 20 km from the homestead. This mine had mostly
chrysocolla as the ore, but I have found some nice malachite
pseudomorphs.
