First Narrows Confirms Lupita Eluvial Gold Zone in Sonora, Mexico

Follow-Up Sampling Recovers Additional Coarse Leaf Gold Grains; Trenching in Progress

VANCOUVER, BC--(Marketwire - August 29, 2007) - First Narrows Resources Corp. (TSX-V: UNO) (PINKSHEETS: FNRWF) ("First Narrows" or the "Company") is pleased to announce that Minera FNR de Mexico, S.A. de C.V. ("FNR"), First Narrows' wholly owned Mexican subsidiary, has confirmed the presence of coarse leaf gold grains in eluvium at the Lupita Gold Zone (the "Lupita Zone" or "Lupita").

Dr. Adrian Mann, P.Geo., the Company's independent Qualified Person for the Susana D'Oro property, has recovered an additional 175 angular and leaf-like gold grains from the Lupita Zone, indicating the presence of a nearby, at-surface, bedrock gold zone. Dr. Mann sampled approximately 0.09 of a cubic meter (3.0 cu. ft.) of eluvium from 4 large samples taken across strike 3 meters (9.8 ft.) apart (9 meter or 29.5 ft. width), and 0.3 to 0.6 meters (1-2 ft.) above bedrock from west to east across the Lupita Zone occurrence, yielding 108, 2, 3, and 62 grains of gold upon panning, respectively.

Statistically, the grains showed a size range similar to those recovered from FNR's discovery samples (see previous news release of July 20, 2007). The largest gold grains obtained by Dr. Mann occur as thin and leaf-like measuring up to 4mm x 2.5mm x < 0.3mm, with slight rounding to the nugget edges. The smallest grains measure 0.05mm in diameter. 4.5% of the grains are < 4.0mm and > 3.0mm in size; 29% are < 3.0mm > 1.0mm; and 66.5% of the grains are < 1.0mm.

A total of 298 grains of gold have been recovered from the eluvium to date from < 0.34 cubic meters of eluvium. The continued recovery of large leaf-like gold grains strongly suggests the nearby presence of a significant bedrock gold zone. Outcrop occurs approximately 0.3 to 0.7 meters (1 to 2.3 ft.) below the eluvium and angular chips and fist-size boulders of weathered rusty granodiorite, quartzite, magnetite, and quartz are present in the eluvial material.

Trenching, mapping, and further sampling of the occurrence are in progress. The Fe-Oxide anomaly associated with the Lupita Gold Zone extends for up to 700 meters (2,297 ft.) in length and appears open on trend to the northwest beneath valley floor alluvium. The source of the gold is interpreted to be an Fe-Oxide-Cu-Au (IOCG) Au-Fe (Cu-Ag) mineralized structure beneath the Fe-Oxide zone which lies directly along the northwest trending Santa Barbara fault zone, well known for its gold potential. Many small historical 'gambosino' (small miner) pit operations occur down slope and downstream from the Lupita Zone and along the Santa Barbara fault for many kilometers.

Dr. Adrian Mann, a registered member of the APEGGA as a professional geologist (#M50794) who has extensive experience with small mine operations, has visited the Property and is preparing a mineral potential assessment and exploration proposal report on the Susana D'Oro property in accordance with National Instrument 43-101. Dr. Mann has reviewed and approved the content of this news release.

FNR either owns or has the right to earn a 100% interest in all Susana D'Oro claims, totalling 11,540.5 hectares (28,517 acres). Located approximately 105 kilometers (kms) east of the city of Hermosillo, the Property includes a former producer of copper, gold, and silver from three high-grade sulphide zones along a vein greater than 1,000 meters (3,280 feet) in length. Historical mining appears to have been limited, at least in part, by the height of the water table.

Geologically, the Property lies within the western part of the Sonora copper-molybdenum porphyry and gold mineral belts, favourable for the occurrence of high-grade Au and Cu-Au-Ag-Bi (Mo) veins that offer an opportunity for near-term production and cash flow. Additionally, it is apparent that the geological setting is favourable for the occurrence of world class (larger tonnage/lower grade) Cu-Au-Ag-Bi (Mo) porphyry or breccia style deposits, as evidenced by the Company's recent Luisa Gold Zone discovery.
