SPOKANE, WASHINGTON--(Marketwire - Aug. 12, 2011) - St. Augustine Gold and Copper Limited (TSX:SAU) is pleased to announce the intersection of highly mineralized sample intervals in two recently completed drill holes (SAG01 and SAG02) with resulting assays that compare favorably with the gold and copper grades predicted by the block model from the mineral resource estimate disclosed in the NI 43-101 October 2010 Technical Report. These results are supported by a positive third party site visit audit report on the overall King-king Project drilling and geology programs. Andy Russell, President and CEO, states, "These intercepts confirm the high quality and integrity of the existing King-king data. The grades in SAG01 are extremely compelling with 99 meters of greater than 1 g/t gold and 1.1% copper."

King-king is a world class copper and gold porphyry deposit with measured and indicated resources of 792 million tonnes grading 0.37 g/t gold, 0.28% copper and 0.815 g/t eq. gold (October 2010 Technical Report for King-king). The King-king deposit is a porphyry copper-gold deposit hosted by hornblende-biotite diorite porphyritic rocks that intrude interbedded sediments, submarine volcanic rocks, and volcanoclastic sediments. Copper and gold mineralization occurs at or near the apex of the composite diorite intrusive complex within the intrusive rocks and extending well into the surrounding wall rocks. The majority of the copper mineralization consists of chalcopyrite and bornite. Gold is relatively abundant in the oxide zone above the deposit's main sulfide zone, and also occurs in the sulfide zone in free form in close association with bornite and other sulfides.

Equivalent g/t gold (Eq Au) levels are used in various places in this release to illustrate the combined effect of the two metals in this project, gold and copper. The following calculations were applied to calculate the Eq Au in the oxide ore and the sulfide ore:

Eq Au (Oxide) = Gold + 1.399 x Total Copper

Eq Au (Sulfide) = Gold + 1.668 x Total Copper

These equations were derived from the parameters listed in the table below that was taken directly from the October 2010 Technical Report for the King-king Project.

The current drill hole database consists of 276 holes representing 89,922 meters of drilling with an average drill hole spacing ranging from 94 to 125 m. The lower extent of the deposit is often open, with numerous historic holes that terminated in ore grade mineralization. The potential for discovery of additional mineral resources in both the undrilled portion of the deposit as well as in outlying areas of the mineral property tenement is regarded as excellent.

The King-king drilling to support metallurgical, geotechnical and hydrogeological components of the King-king feasibility study is progressing well, with 80% of the 15 hole program completed. The four metallurgical core holes have been completed to collect samples for additional metallurgical testing that St. Augustine anticipates will confirm current process designs developed based on samples from existing core tested in the first half of 2011. Five holes (80% of plan) of the planned 6 have been completed for the open pit geotechnical evaluation. Three of the planned five hydrogeological holes have been completed for the project's hydrogeological assessment.

Analytical results for SAG01 and SAG02, two of three holes completed to date that were designed for confirmation of the October 2010 mineral resource estimate and to provide core for metallurgical test work have been received from Intertek Lab in Muntinlupa City, Philippines.

Drill hole SAG01 is an angle hole (azimuth: 205 degrees, dip: -66 degrees) drilled in the central eastern portion of the copper-gold deposit. The grades for various intervals are illustrated in Table 1 below including those predicted by tracing the hole in the block model.

SAG0 2 is an angle hole (azimuth: 184 degrees, dip: -71 degrees) located in the central part of the deposit that laboratory results show also has significant thicknesses of Eq. Au mineralization. The grades for various intervals are illustrated in Table 2 below including those predicted by tracing the hole in the block model.

The project's drilling contractor is DrillCorp, Carmona Cavite, Philippines. The assay laboratory is Intertek Testing Services, Muntinlupa City, Philippines. The geotechnical core testing company is Geotechnica, Manila, Philippines. These firms are currently primarily focused on collecting and analyzing additional data and samples for the geotechnical, hydrogeological, and metallurgical studies that will form the basis of the feasibility-level mine design (pit slope stability study), process design (sulfide flotation concentrator study), tailing disposal system design, as well as supply information for the waste rock and tailing characterization and for evaluating surface and underground water impacts and mitigation plans for the feasibility study.

Additionally, the Company has received a positive site audit report from Donald Earnest, PG and President of Resource Evaluation Inc. (REI), Tucson, AZ (consultant on the feasibility study team). As part of continued operations and the current feasibility study work program, there will continue to be an on-going audit and review of King-king's site management data collection process and procedures. The current drill program, core handling, and assaying procedures at the drill-site and core storage facility, and the activities at the independent laboratory facilities for sample preparation and analysis are being conducted with the highest standards of quality control to assure accurate results in order to maintain the project's existing integrity.
