Site “S-10”, Location: Santo António de Penedono Mine, Penedono, Portugal 41º01’16.6”N, 7º24’27.4”W
This defunct gold mine is located near the small village of Granja, 3 km away of Penedono, north central Portugal. Its mineralization is basically arsenopyrite in quartz veins, linked to second order shear zones related to the tip of the Malpica-Lamego shear zone, developed in the granites. The mine ceased its activity in the late 1950s, but has been subjected to exploration drilling during the last decade. Our goal is to determine the feasibility of gold phytomining in the tailings of this mine through ex situ and in situ trials.
