After a long search, I cannot prove this location:
Terra Corrida claim (Baixão claim), Coronel Murta, Minas Gerais, Brazil

The reference in Mindat: https://www.mindat.org/loc-69571.html is brief and as it is another claim called 'Baixao', well known for its Tourmalines, in Itinga, Brazil, I have doubts about whether there are two 'Baixão' localities or just one.
The 'Baixão' of Itinga has several scientific references, like this one, for example:
https://inis.iaea.org/collection/NCLCollectionStore/_Public/20/007/20007425.pdf
and yet I have not been able to find any scientific reference to the 'Baixão' of the Coronel Murta.

Does anyone know more about these two locations?

Hi Jordi,

I was looking up the locality for the Itinga Baixão mine for photos I had taken. In Mindat, the changes history shows that the Coronel Murta locality was once the same as the Itinga locality then changed back to its own. Mindat user, Reynaldo Contreira, provided some data but this was overwritten by others, assumedly not from Brazil. The only reference given for the locality is: Morteani, G., Preinfalk, C., and Horn, A.H. (2000): Classification and mineralization potential of the pegmatites of the Eastern Brazilian Pegmatite Province. Mineralium Deposita 35, 638-655. This reference was later removed. I do not have access to this reference, so I cannot tell you what it has to say, but perhaps you have access.

Best,
Mark

Thanks Mark, I already saw it, and Reynaldo Contreras was the latest person to fix both localities in Mindat. I have total confidence with Reynaldo, so, I assume that in fact there are two 'Baixão' locations in Brazil, both with Tourmalines. Solved issue.
