Just looking at this mineral list and surprised to see Voltaite with a question mark. It is listed in Minerals of Nevada according to the detailed info (which I guess I cannot augment or edit). I have seen a specimen in the collection of R. Thomssen and I don't have any doubts about Voltaite coming from there. Anatase could be added to the list for that location too, but that would probably frighten too many people. http://www.mindat.org/forum.php?read,6,261488,261488#msg-261488 Thu, 23 May 2013 23:31:06 +0000 Phorum 5.2.15a http://www.mindat.org/forum.php?read,6,261488,261803#msg-261803 http://www.mindat.org/forum.php?read,6,261488,261803#msg-261803 David Von Bargen General Sat, 26 May 2012 16:03:29 +0000 http://www.mindat.org/forum.php?read,6,261488,261762#msg-261762 http://www.mindat.org/forum.php?read,6,261488,261762#msg-261762 Interesting specimen in any event. I just took two photos and added them to the collection.
One is under Sulphur, the other under Anglesite.

So, this has worked out differently than I had expected and rather than removing the question mark from Voltaite from this location, it looks like another question mark should be added or better yet, that it be removed from the list altogether.]]> Tom Trebisky General Fri, 25 May 2012 22:40:59 +0000 http://www.mindat.org/forum.php?read,6,261488,261564#msg-261564 http://www.mindat.org/forum.php?read,6,261488,261564#msg-261564 -------------------------------------------------------

I wanted to say that I thought this was an excellent article, the kind of thing I like to read, and the sort of thing I would
aspire to write. Enough photos to raise the pulse rate a bit -- they clearly put in a lot of effort and made a real
contribution. The only thing lacking was a map or two of the mine, I am sure that was due to space limitations.

But, I am dismayed when a specimen in hand identified by a reliable source gets questioned and an article is
cited, I presume as the absolute authority. I am reminded of a time when a company I worked for was sent some
papers with numbers, assays, and ore grades on them (handwritten or typed, I don't remember). The client asked us
if we could have the numbers printed on computer paper. This was in the day when computer paper was wide stuff
with green horizontal stripes and holes on the right and left to feed it through a high speed line printer.
The purpose of this subterfuge was they wanted to present the numbers at a board meeting and felt they would
have more "weight" if they looked like computer output. (I suppose I am dating myself by describing all of this).

Now, I am not suggesting any subterfuge on anyones part right now, just pointing out the magical authority that
comes upon anything that is printed or published.

I have a specimen of the material in hand right now, am admiring it under the microscope, and will see what I can
do about getting some tests run.]]> Tom Trebisky General Wed, 23 May 2012 18:30:47 +0000 http://www.mindat.org/forum.php?read,6,261488,261554#msg-261554 http://www.mindat.org/forum.php?read,6,261488,261554#msg-261554 David Von Bargen General Wed, 23 May 2012 17:59:46 +0000 http://www.mindat.org/forum.php?read,6,261488,261541#msg-261541 http://www.mindat.org/forum.php?read,6,261488,261541#msg-261541 -------------------------------------------------------

Been there, done that.

These aren't the only guys who have collected in this mine.]]> Tom Trebisky General Wed, 23 May 2012 16:43:50 +0000 http://www.mindat.org/forum.php?read,6,261488,261538#msg-261538 http://www.mindat.org/forum.php?read,6,261488,261538#msg-261538 Uwe Kolitsch General Wed, 23 May 2012 16:29:43 +0000 http://www.mindat.org/forum.php?read,6,261488,261519#msg-261519 http://www.mindat.org/forum.php?read,6,261488,261519#msg-261519
