Jack Schrader purchased the NWA 4936 stones and I purchased
the paired NWA 5406 lunar stones from a Moroccan dealer
(List member) who told us this material was found near
Siksou Mountains in southern Morocco (Western Sahara). The
classifying scientists were also told this same information
by the Moroccan dealer. Here is a link to two photos of one
of the finders provided to me, is that you Aziz?

2) http://www.lunarrock.com/nwa5406/siksou2.jpg
I was also provided an image of some of the stones next to
a GPS with coordinates clearly visible. A Google Earth
search places the spot south of Laayoune and SSW of Smara in
Western Sahara.
Aziz, I appreciate your wanting to correct any false
entries in the Bulletin like the rest of us. If Jack and I
were provided with a false find location for NWA 4936/5406,
please let us know what you know. If we were lied to, this
is something only concerned Moroccans like yourself can try
to correct with your fellow countrymen. If we were provided
with false information, please contact your local friend and
sometime partner in Morocco, he will want to correct any
erroneous find locations as well. 'Confusion' like this is
why meteorites found in the Sahara desert are assigned with
an "NWA" designation number instead of an actual name of
where they are found, or reported as found from. There is
simply no confidence in this data because of a variety of
reasons (i.e. keep the site secret, the finder did not have
GPS, etc.).
Here is part of my description for NWA 5406 that tries to
explain another problem with original distribution of NWA
4936/5406:
>>
Initially there was some confusion concerning the combined
Total Known Weight (TKW) of pairings of NWA 4936/5406 due to
mismanaged distribution of the original eight stones by a
Moroccan dealer. Eventually the puzzle was put together.
After thorough searches of the find site, it has been
established that there are eight individual stones that
together constitute NWA 5406 (six stones 281g) and NWA 4936
(two complete stones 179g and one 20g type sample from one
of the NWA 5406 stones) for a combined Total Known Weight of
480 grams. Two of the eight stones (179g total) were
purchased in 2007 by a collector, who removed 20 grams from
one of these complete stones and submitted it to a second
scientist for classification without realizing the material
had already been classified. Months later the two
classifying scientists were able to piece together the
puzzle when the final four stones were purchased, and
another 20 grams was submitted and classified under the NWA
5406 designation. Luckily, all eight stones were proved to
come from a single Moroccan dealer and/or finder then
classified by the same scientist! In all, a combined total
of 60.1 grams in type samples have been deposited at UWS and
UAz.

I hope this helps, Thank You for your concerns!
Best regards,
Greg
