First Gold Exploration Inc.: First Gold Exploration and X-Ore Resources Complete a New Resource Estimate on Croinor

LAVAL, QUEBEC--(Marketwire - Aug. 11, 2009) - Managements of joint-venture partners (TSX VENTURE:EFG)(FRANKFURT:F12) and X-Ore Resources (TSX VENTURE:XOR) are pleased to release a new NI43-101 compliant resource estimate for the Croinor property, located east of the town of Val-d'Or, Abitibi, Quebec.

This new resource estimate follows two years of intensive exploration drilling (approx. 13,000 metres) along the down dip and lateral extensions of the Croinor gold deposit. All results have been compiled and a re-interpretation of the entire deposit was performed. It is now believed that the deposit consists of numerous east-west elongated, shallowly north dipping and plunging mineralized shoots. This is a significant change from previous interpretations which indicated a series of discontinuous tabular structures. Individual mineralized shoot extends laterally from 50 metres up to 250 metres.

The following tables show the indicated resource and the measured resource for each vein and finally a summary of the indicated and measured resources at cut-off grades of 5 g/t Au (base case for the resource estimate) and 7 g/t Au.

This new NI43-101 compliant resource estimate was performed by Pierre O'Dowd, P. Geo., independent consulting geologist and Qualified Person under NI43-101, based on the review of 832 diamond drill holes and all available technical information and previous report. The latter used the same geological parameters as the ones used by the firm InnovExplo for its 2005 estimate. The main parameters are:

- Minimum mining width of 1.8 m;

- Polygons drawn on cross sections;

- Polygons extend vertically and laterally to half the distance in between intercepts to a maximum of 20 metres;

- Grade capped at 65 g/t Au;

- Specific gravity of 2.8;

- 5 g/t Au cut off as base case.

This current estimate shows a 15% increase in the number of ounces of gold over the 2005 estimate (from 206,792 oz Au to 238,414 oz Au). As noted above, the average grade of the deposit, using 5 g/t Au cut off grade, was established at 9.11 g/t Au. A technical report presenting all information pertaining to the resource estimate, in conformity to Appendix A1 of NI43-101, will be filed shortly on Sedar within the prescribed time frame.

In recent news, it was announced that a scoping study was completed based on the 2005 resource estimate (July 2009). The scoping study, performed by Golder and Associates of Val-d'Or, indicates that approximately 80,000 ounces of gold could potentially be extracted economically at Croinor. It is believed that, based on the new resource estimate and the new geological model for the mineralization, the economics of the deposit can be further improved. The partners, First Gold and X-Ore, have now started the procedures to obtain necessary permits to initiate the rehabilitation of the underground workings. Note that this scoping study is preliminary in nature and includes mineral resources that are not mineral reserves and do not have demonstrated economic viability. There is no certainty that the preliminary assessment will be realized as presented since certain engineering parameters related to construction, environment and rocks mechanics will have to be validated at the preproduction phase.

The revised model for the deposit opens a significant area of prospective ground which will hopefully increase resources while the development of the deposit is ongoing. Previous programs targeted the up and down dip extensions of known auriferous intercepts. Future drilling programs will target lateral extensions which exhibit a much better continuity.
