Avrupa Minerals Ltd. (TSXV:AVU) announced the commencement of fieldwork to upgrade their Covas tungsten project in northern Portugal, near the border town of Caminha.
The press release is quoted as saying:
The Covas project consists of a ring of wolframite- and scheelite-bearing skarn deposits surrounding an uplifted complex of multiple granitic intrusive bodies covered by metamorphosed sedimentary rocks. Known high grade skarn mineralization is located in a specific limey stratigraphic horizon that surrounds the intrusion complex, known as the Covas Dome. The source of tungsten skarn mineralization is probably related to emplacement of one or more of the intrusive bodies. Two intersecting, regional structural features, one trending north-northwest and one trending northwest, control the emplacement of the intrusions, and thus, along with favorable host rocks, the location of skarn mineralization.
