Cannot find any information about this locality neither its minerals (Rui Nunes, 21 May 2014).

Segundo informação do Dr. Luís Lopes (U. Évora), parece que nesta freguesia existe uma herdade com esse nome mas nada sabe sobre uma eventual ocorrência de Cu (Rui Nunes, 17 Fev 2015).

See http://www.mindat.org/mesg-25-324894.html

Note:
This Mine/copper occurrence is situated between two farms: Alcalainha (Monte da Alcalainha) and Alcala (Monte da Alcala). Perhaps for this reason some mineral collectors have been using the term 'Alcala Mine' (which doesn't exist, at least as an official mine/claim).
