"These new drill results are interpreted as the south easterly extension of the recently announced Blue Quartz Prospect, some 500m to the south east and have resulted in a series of high grade intercepts over a strike length of 1.5km south east of the current pits. Drilling is continuing in this area and more results are expected when assays are received." said Michael Carrick, Chief Executive Officer of CGA.

The Boards of CGA Mining Limited ("CGA", the "Company") (TSX :CGA, ASX :CGX) and Filminera Resources Corporation are pleased to provide additional new exploration results from recent drilling. High grade drilling intercepts have been identified at the Capsay/Old Lady Prospect, immediately adjacent to the Blue Quartz Prospect. These holes are indicated in blue in Fig. 1. The zone is again outside the Masbate Project's current 43-101 resource or reserve estimates.

See http://files.newswire.ca/578/CGA_Capsay.pdf for Fig. 1 and Table 1 outlining the location of significant drill intercepts for Capsay/Old Lady Prospect

The Capsay/Old Lady Prospect lies 3.5kms from the Masbate Plant site and approx 1.5kms from the southern limit of the exisiting Main Vein pit. It is interpreted as the SE extension of the recently announced Blue Quartz Prospect (see 1 July 2010 announcement) and lies 500m to the SE of Blue Quartz Prospect.

Set out in Table 1 are the assay results for reverse circulation holes ODRC001 to ODRC007.

Relatively wide intercepts occur in ODRC001 (9m @ 1.35g/t from 60m), ODRC003 (10m @ 1.70g/t from 22m), ODRC004 (12m @ 3.0g/t from 51m and 10m @4.82g/t from 81m), ODRC006 (16m @ 1.20g/t from 48m) and ODRC007 (25m @ 2.13g/t from 29m).

Previous mining by Atlas Mining Corporation at Capsay/Old Lady from open pit and underground operations produced 544,867 tonnes at a grade of 1.97 g/t Au.

The current 37 hole RC Drilling Program is initially planned on an average 50m x 50m grid pattern to cover the known mineralized quartz veins at the Capsay/Old Lady Prospect. 17 RC drill holes have been completed with results received only for the 5 holes reported above.

The project has a total indicated resource base of 4.55M ounces (153.41mt @ 0.92 g/t), total inferred resource base of 3.22M ounces (127.15mt @ 0.79 g/t)and a probable reserve of 3.03M ounces (92.2mt @ 1.0g/t) of gold. In its first year of operation the project produced in excess of 150 000 ounces and is on track to produce at a rate of over 200,000 ounces per annum. The 4Mtpa plant was constructed by Leighton Contractors Asia Limited ("Leighton") without one lost time injury. The mining contract for the Masbate Gold Project was awarded to Leighton, the largest mining contractor in the world.
