Rio Tinto Copper Mine is EMED Mining’s main project and area of activity and is located in the Iberian Pyrite Belt, 65 km northwest of Seville, Spain. The open-pit mine and processing facilities have been on care and maintenance since mining ceased in 2000 due to low copper prices of less than $1.00/lb at the time. EMED Mining was granted an option to acquire the operation in May 2007 and it was subsequently acquired in October 2008.

Since then, EMED Mining has undertaken extensive studies on the mine. This work has been independently reviewed by AMC Consultants and Behre Dolbear International. Key anticipated production parameters are detailed in the Behre Dolbear NI 43-101 Technical Report On Reopening the Rio Tinto Copper Mine dated 17 November 2010 and an updated report dated February 2013.
