Hi Patrick
Good work, we need people like you to fill in these gaps. I will get back to updating this article shortly. BTW, there is little info and no mineral list for Ewingar Ck on Mindat - if you can let us know of anything you have found in the area it will be most helpful?
regards
Ralph

This Quartz is from Thulimbah, in SE Queensland, just north of Stanthorpe.
This find was made when the Queensland Main Roads Dept were building a new highway,
just 200 meters from the eastern Queensland / NSW border.
Most of the crystals were double terminated, the second termination was usually clear with multiple points.
Quite a number were up to 60 cm long, this specimen is just a baby at only 18.5 cm x 6.5..

Hi Ralph, I've updated the locality data and mineral list for Ewingar Creek. I'll add some further localties and specimens soon.

Thanks for the image above Phillip, nice big crystal! I heard of a similar find at Wallangarra (south of Stanthorpe, near the QLD border) some years ago, also in a road cutting when building a new highway....could they possibly be the same deposit? Have you heard of the Wallangarra find?

Thanks,

Patrick

No Patrick, different find, l hadn't heard of the Wallangarra find, please tell us about them, how long ago was it made?.
The one l posted is from Thulimbah, about 15 Kms north of Stanthorpe & those roadworks were done maybe 16 or 17 years ago.
A friend of ours is a building contractor in the area, (whom l often contract to) 2 years ago he built a house at Cottonvale, a few Kms further north & found quite a few Smoky Quartz crystals when they were doing foundations, up to 30 cm long.

Well done Ralph and also to all the contributors. This is an excellent body of work and as Ralph states is probably only a little of what is actually out there and known.

I have fond memories of Amethyst Castle myself; most of what I collected there has been put through the tumbler and would not be representative of chevron in its natural state. Two places I will mention in Victoria that have not been mentioned ( and I will attempt to take photo's the next time I am at both places) are the spectacular clear quartz clusters with scatterings of pyrite throughout from the Morning Star Mine at Woods Point; and sensational double terminated pieces with enhydro inclusions from Specimen Gully near Chewton.

There is also an amethyst locality called the White Swan Crystal Mine near Mount Kooyoora, near Rheola In Victoria; this site is now closed for collecting as it is in a National Park. Torbernite and autinite are also found at this locality.

Wow; what a labour of love. Well done again.

Hi again,

Although the Entia Valley in Hart's Range, Northern Territory has already been mentioned for Scepter Quartz, the Quartz crystal bearing veins extend much further south to Harding Springs and probably beyond.

I was able to collect several nice specimens from the Harding Springs area over the last few years. Some highlights are:

Also in the same area, other Quartz veins produced some large clear Quartz crystals, including this one (unfortunately has a contact termination):

Hi Phillip
This is great info.
I added a site for Thulimbah, if you could add this picture and any others it would be good. Any Pix and info on Cottonvale would be good to add too.

Patrick - good work on the Ewingar site; any more info and pictures for Wallangarra - should we add the site too?
The Harding Springs crystals look great - I have added these too, if you have any more info please add it. I only heard of this site in the last year, but it looks fabulous.

Neil,
I have seen quite good specimens from Amethyst castle too, but most what I collected also ended up in the tumbler etc too. If you have any pictures & info of specimens from the Victorian sites, please upload them and I will add them in due course.

Its good to get all this help, its filling in the gaps well (anyone from Western Australia though?)

Regards,
Ralph

This Quartz crystal is from Severnlea, approx 8 Kms south of Stanthorpe, SE Queensland.
l found it sandwiched between rocks & as a result it had no room to develop faces on the sides,
but it has always been a favourite of mine, as it has a fantastic termination.
l found it some 10 years ago, size is 11 x 6.5 x 4.5 cm wide.

Hi all,

Re. the Wallangarra site, I'll try to find out a little more info on exactly where the crystals were found. I have seen specimens from this area in several collections, but haven't collected any from here myself. I'll also try to fill the blanks as best as possible on the other Quartz locations I've mentioned. Does anyone have any specimens or further information on the beautiful lustrous Smoky Quartz from "Baxter Prospect", Olary, SA? These appear in Albert Chapman's collection in Sydney, and rank as some of the finest smoky Quartz from Australia. It seems very little is known about this location.

Nice crystal Phillip, looks like it grew up against some feldspar crystals. Some of the vughs around Ewingar have produced large flat sheets of fully crystalised Smoky Quartz. I'll try to find one and photograph it.

I know Kuridala has been mentioned and well documented before, but thought I'd share this whopper of a crystal (14cm x 13cm)...

Patrick l know the Smoky Quartz crystals that you are referring to in Albert Chapman's collection,
having personally seen those specimens, from memory they would be about 2 1/2" long.
Albert told me that he was driving along with Flossy Campbell (an old time Broken Hill collector) towards Broken Hill, when they saw old tyre tracks leaving the highway, possibly made by a Model T Ford Albert said, they followed them & came upon an old quarry, which hadn't been worked for many decades.
Those Smoky Quartz crystals were in clay filled pockets if l rightly remember & it would have been on the northern side of the highway.

Hi Philip,

That description sounds about correct. I did some research on this some time ago, and turned up some interesting info on a few locations around Olary. There is one deposit listed near Plumbago homestead as containing "large smoky quartz crystals in cavity in pegmatite", and in another report on a mine near Bimbowrie Homestead, "Large terminated quartz crystals were obtained from mansized vughs in the western quarry"

The only deposit listed in any reports as "Baxters Prospect" is a small working on a Sillimanite lense, and certainly doesnt contain any quartz crystals. But Baxter also was a mine operator on several other workings from what I can gather.

Its quite possible that there are a number of vughy pegmatites in the Olary area.

I will see what I can find on Baxters prospect. We have some nice ones from Weekeroo and near Dome Rock (some I found myself) in this area, and should find better pix from Kings Bluff.
I have added some of the new data, but can you upload the pictures from Severnlea, Philip?
Please keep all this useful data & pix coming.

Regards,
Ralph

With all the help and contributions, I know the Australian Quartz best minerals article will be a good one. Perhaps we can get someone to help by submitting good pictures of fine tigereye, chrysophrase, chalcedony and opals. We must not forget those.

Hi Ralph,

Thanks for looking into the Baxter's Prospect location, it's quite possible that the mine that Albert Chapman collected those smokies from was later renamed.
While on the topic of Kings Bluff at Olary, I did manage to find one specimen that has crystalised Gold (?) included in it. It was hard to capture the inclusion with a camera, but it is distinctly crystalised in small hopper crystals and has a definite dull metallic lustre. These were reported to occur at Kings Bluff in a few reports and journals, and the specimen pictured was collected from a small vugh right on the edge of the cliffs on top of the hill.

According to Mark Willoughby the Baxter site is probably Maggies feldspar mine (http://www.mindat.org/loc-215318.html ), though it does not list quartz.

Howdy All,

The location description that Philip gives does not match the geology reports for either the Maggie Feldspar mine (Baxter), a pegmatite location,
or the near by Baxter Diggings (Maggies Claim), which are only small pits.
And yes, they are the correct names!
They are seperated by a small group of hills that run in a SW to NE direction beside the road to Tietz Dam, a well known Beryl locality. They are both entered on here if you wish to have a look at them.

However, I will look through the records of the other localities in the area and see if I can find any quarries with that description!
It should not be too hard as most of the quarries in that region were for pegmatite minerals
I'll post back as soon as I can with the results.

Cheers Mark.

Howdy All,

Sorry for the delay on this one, uni kind of took over my live for a few weeks.

I've been through all the old Mine Summary Cards and records I can find and I tend to think that the most likely spot for this specimen is the Raven Hill South Mine, interestingly SARIG now class Raven Hill and Raven Hill South as two different deposits, when historically they are listed as one. I do agree with their logic though as the geology is different at both even though they are only about 200m apart.
Teitz Dam is only a locality and the closest mine is the Boundary Mine (Nejaims Claim; Varischettis; Teitz Dam North) and again it is the wrong geology for the specimen.
I’ve added Raven Hill South and I’ll add the other localities later this week with a few more that I have ready. For now though I think that the label for these quartz specimens of Albert Chapman's should read, Raven Hill South Mine, Old Boolcoomata Station, Olary Province, South Australia, Australia.

Cheers Mark.

The sceptre crystals from the Entia valley has fascinated me ever since I read the article by Don Mc Coll in the Mineralogical record, Vol 33, number 6, 2002. The contributions, especially the photos, of Patrick Gunderen are very interesting. Those specimens of quartz reminds me a lot of the very similar crystals from Brandberg, Namibia. I live in Ceres, South Africa, and have a passion for quartz and spend a lot of my time roaming around our mountains looking for deposits. I would like to make contact with Australians who have a similar quartz passion. Please visit our blog with photos and notes of our outings in search of quartz.
