The Curuglu Mine is located in Canada de Curuglu, a branch of Arroyo del Boleo. The mine is WSW of the Amelia Mine by less than 600 m on the surface and separated by a ridge, but underground they were only separated by the Curuglu fault that offset ore bed no.3.

In order to transport ore from the Curuglu mine out to the railroad in Arroyo de la Soledad, the Curuglu tunnel, 437 meters long, was driven through the ridge at the head of Arroyo de la Soledad, from near the Amelia shaft to Canada de Curuglu. A bridge 137 meters long and 35 meters high was constructed across Canada de Curuglu, and electric locomotives pulled ore cars across the bridge and through the tunnel to the former railhead near the Amelia shaft.
