I've just transferred in a bit more data for gallite from the 'Handbook' and from the original Amer. Mineral. new mineral abstract. But I note that whereas the Handbook and Dana 8th edition both give the type locality as Tsumeb, we have listed Kipushi. The new mineral abstract mentions both localities, but the authors (Strunz et al.) studied Tsumeb material, while acknowledging that the species had also been reported from Kipushi by Uytenbogaardt, so it looks like Tsumeb is correct. Can we correct, please?]]> Andrew G.

Also the Burrows reference cited has been superseded by: Ontario Dept. of Mines, 1968, MRC No.10, Silver Cobalt Calcite Vein Deposits of Ontario, by A.O.Sergiades everything prior to 1968 should be confirmed by this publication which includes the coordinates ( publication is free online at the Ontario Department of Mines website) .
Furthermore claims should not be entered in the database without coordinates as the names constantly change depending on who it belongs to at the time. Also claims are tracked by claim numbers rather than staker's name and it is only in some publications that the claim holders name is referred to at the time the research was done for the publication.
[www.mindat.org] this is also the same as the Walsh mine and represents the ownership of the original Walsh claims from 1912-24 by Miller Lake Silver Lodes Mining Co.(Hart claims: 135, 136) Like most old mining properties the ownership has changed many times aqnd so have the claim names. In the case of the Walsh mine it has been covered by the following claims

1912: Walsh claims 98 and 3879
1917-18: Crown Reserve Mining Co. held option

There are two types, ones completely replaced by scorodite and ones replaced by pharmacosiderite. The ones replaced by predominantly pharmacosoderite (confirmed by XRD, see: [www.mindat.org] ) always have a core of unaltered cobaltite and may also contain some scorodite. However, they should be called pharmacosiderite pseudo cobaltite, not scorodite pseudo cobaltite. What confuses things is that there is a transition from predominatly pharmacosiderite to predominantly scorodite depending on the degree of alteration. Generally the more surviving cobaltite the more pharmacosiderite so you can get a rough idea of which is predominant by the specific gravity.]]> Reiner Mielke Mistakes and Errors Mon, 29 Apr 2013 11:33:29 +0000 http://www.mindat.org/forum.php?read,7,292419,292419#msg-292419 http://www.mindat.org/forum.php?read,7,292419,292419#msg-292419 Photo No. 15129

Pittong is about 35km from Ballarat and in a different shire (Golden Plains Shire). I have seen Ballarat listed as a "Sub Region" for Pittong, whatever that is, but the Sub Region for Tylden is Bendigo, not Woodend, so that makes no sense. Tylden certainly is not part of Woodend, both of which are simply towns near one another.

Smythesdale is another town just up the road from Pittong, and it is listed under Golden Plains Shire. It should simply be Smythesdale, Victoria.

Jindivick is shown under Baw Baw Shire. I think that the Shires should be removed as the boundaries can change with any change in Government! And their use is very limited in Mindat already.

There are probably others.

I think that where a town exists, then that should be sufficient. Therefore Pittong, Victoria and Tylden, Victoria.

I have changed these two. If I get time, or as I coma across such issues, I will clean up the others.

The specimen on the photo is 6 x 4 x 1,3 cm. which is an average size of the specimens.
By looking up the locality on Mindat, I found it immediately and the only mineral mentioned from that location in the text is baryte, although the mineral list is empty ???
[www.mindat.org]
I have uploaded this same photo as attached on Mindat and hope that it will appear soon on the locality site.
Included in the baryte crystals are tiny crystals of presumably marcasite.

Scrap the latter.
Tegengren mention 3159 as "Loos koboltgruvor", Loos Cobalt Mines. Perhaps better to writeit as "Los Cobalt Mines, Los, Hälsingland...."

Tegengren mention it was found as a copper mine- the amount was very insignificant& the pit not more than 2,7 m deep.
