St. Augustine Gold & Copper Limited and Nationwide Development Corp. Agree Basis and Assurance for Further Earn-In Investment on the King-king Copper-Gold Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 10, 2011) - St. Augustine Gold and Copper Limited (TSX:SAU) is pleased to announce that it has agreed and executed with Nationwide Development Corp. (Nadecor) an Interim Funding Agreement (IFA) for St. Augustine's additional investment in the King-king gold and copper project (King-king Project) located in Pantukan, Compostela Valley, Philippines. The additional investment covered by the IFA is investment over and above the USD 30 million in project expenditures covered by the Preferred Share Investment Phase of the overall earn-in agreement but prior to the Joint Venture Phase. St. Augustine expects that it will invest an estimated additional USD 60 million, part of it under the IFA, to complete its full earn-in interest by Q2 2012 when the bankable feasibility study is forecast to be completed. Upon completion of earn-in, both parties will fund, on a retained interest basis, all future cash calls needed for the joint venture with respect to the remaining King-king Project development costs.

The IFA confirms that all expenditures and investments made by St. Augustine for the King-king Project during the Interim Funding Phase (as established under the IFA) will be treated as earn-in and provides flexibility for both parties to optimise usage of funds. Such earn-in will eventually translate into an interest in a joint venture entity which is intended by both parties to be the holder of the Mineral Production Sharing Agreement (MPSA) for the King-king Project. Nadecor further confirms under the IFA to comply with the various agreements it has in place with St. Augustine and commits to an agreed timetable of key steps for the completion of the set-up of the above joint venture entity. As assurance for such commitment, Nadecor has given St. Augustine an option over a substantial portion of production from the King-king Project at a material discount to relevant market prices. The option covers a period of 3 years from the King-King Project reaching commercial production and is adjusted for certain circumstances. It is intended that the assurance arrangement (and as abovementioned the IFA) will expire upon the completion of the earn-in with St. Augustine then having a direct interest in the joint venture entity. The completion of the earn-in is currently planned at Q2 2012.

The King-king Project is one of the Philippine Department of Environment and Natural Resources' (DENR's) top priority mining projects. The project has been independently confirmed under both Canadian NI 43-101 and Australian JORC regulatory rules to have a measured and indicated mineral resource of 792 million tonnes and an inferred resource of 125 million tonnes, making it one of the largest undeveloped copper-gold projects in the world.

Mine life is 23 years with a planned throughput of 100,000 tonnes per day.
