Sunridge Gold has been exploring for VMS base and precious metal deposits in Eritrea since 2003 and has successfully defined 4 deposits on the Asmara Project located outside of Asmara which contain significant amounts of copper, zinc, gold, and silver. A Feasibility study is currently examining an integrated mining operation on all 4 deposits and is on schedule for completion in Q2 2013.
The Feasibility Study is a continuation of a prefeasibility study (PFS) completed in May 2012 which considered an integrated mining operation for all 4 deposits with a central mill located at the large Emba Derho Deposit. The Prefeasibility Study demonstrates very robust economics, with the Net Present Value (NPV) of the project was shown to be $555 million dollars with a 10% discount applied ($1.642 Billion NPV with zero discount) and the Internal rate of return (IRR) is 27%.
The integrated mining operation outlined in the PFS details a processing facility at Emba Derho that processes ore from open pit mines at Emba Derho, Debarwa, and Gupo and an underground mine at Adi Nefas.
The current Feasibly Study will differ from PFS as it is considering a staged start up beginning with the mining and direct shipping of 116,000 tonnes of high-grade copper material averaging 16% copper, 3.0 g/t gold, and 77 g/t silver from the DSO Zone at Debarwa. This will enable the project to be in production earlier and will generate early cash flow and reduce initial capital costs.
Also in the staged start up mining plan, a heap leach operation will process the gold from the gold caps early in the mine life and a floatation plant will begin by processing the supergene copper material.
Full production will begin in the 3rd year of operation and will process 4 million tonnes of material per annum. Annual production will average 57.3 million lbs. (26,000 tonnes) copper, 143.2 million lbs. (65,000 tonnes) zinc, 24,000 oz gold, 787,000 oz silver over 13 years of full production.
Total metal production over the life of the mine is 804 million pounds (365,000 tonnes) of copper, 1.789 million pounds (812,000 tonnes) of zinc, 415,000 ounces of gold, and 11 million ounces of silver. Sunridge has now begun a Feasibility Study and is expected to complete in Q1 2013.
Sunridge also continues to explore new targets. Encouraging results from recent drilling at Adi Rassi support Sunridge management's belief that Adi Rassi is a new large copper-gold discovery that has the potential to become Sunridge's fifth deposit on the Asmara Project.
Sunridge is operated by an entrepreneurial team with a proven record of discovery, exploration and development success with companies such as Nevsun Resources Ltd. and Bema Gold Corp.
