I live near Lisbon, Portugal, in the south bank of Tagus River. Such is not a good place for collecting minerals as all the best localities are relatively far.
My main interest are Portuguese minerals and I have a special sympathy for phosphates. However, the feldspar group minerals are my favourites. Crystal twins and pseudomorphs are always welcome home.

I'm strongly committed with the development of the Portuguese information here on Mindat, improving the administrative grid, adding new mineral occurences and reviewing the existing data. A careful attention is given to the new uploaded mineral photos.

If I can help with something from Portugal I'd be glad to lend a hand.

I'm digging on a quartz vein in my all time favourite mine
Any libethenite specimen, however small it may be, observed with the 10 x magnifying len becomes magnificent
Libethenite crystals in situ
Under all this marble is perhaps the best dump for phosphates

Miguel Vacas mine, also locally known as "Mina de Vieiros" or "Cobre de Vieiros", was a copper mine actively exploited between 1925 and 1986. One says that its mining activity goes back to the Roman Empire period but there is no strong evidence to sustain this claim. In the initial phase the ore exploration was carried out through tunnels and galleries; its open-air exploration began in 1979.
