Stealth Minerals Limited: Alexandra Confirmed as a Bulk Tonnage Copper-Gold Prospect

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Sept. 29, 2005) - Stealth Minerals Limited (TSX VENTURE:SML):

Exploration has discovered a coincident soil geochemical anomaly that averages greater than 325 ppb gold (up to 1,038 ppb gold) in a 500 meter by 600 meter area, which is within a greater than 200 ppm copper soil anomaly measuring 1,000 meters by 600 meters. A hand trench cut through the centre of the anomaly returned 187 ppm copper and 158 ppb gold over 160 metres. Another hand trench 150 metres north returned 104 ppm copper and 116 ppb gold over 160 metres. A total of 313 one-metre rock chip samples were taken in the area. Copper values in rock ranged from 30 ppm to 536 ppm. Gold values in rock ranged from 39 ppb to 568 ppb. A stockwork vein system was discovered in the southeast portion of the anomaly near the intrusive contact and high-grades of gold (up 2.1 g/t), with copper up to 0.4% were recorded in outcrop samples.

Alexandra and four other new discoveries in this area are the result of a regional exploration program in an area east and northeast of Quartz Lake, which was the focus of a successful core drilling program in 2004. Surface work has outlined a 6 kilometre northwest trending zone that consists of five showings of which Alexandra is the most southerly. The alteration at Alexandra and the four other zones to the northwest exhibit advanced argillic and high-sulphidation epithermal styles. Other alteration minerals include alunite, illite and pyrophyllite. Gold and silver values have been discovered in occurrences of vuggy silica on the four zones to the north and more work is planned for these new discoveries.

Mineralization at Alexandra is hosted in Toodoggone crystal lithic tuffs. The associated highly-anomalous metal assemblage also contains arsenic, molybdenum and barite. It is believed that this volcanic unit is shallowly underlain by mineralized quartz monzonite that may be genetically related to Sofia, which is a newly discovered copper-gold porphyry occurrence that outcrops about 3,500 metres northeast of Alexandra.

Alexandra represents a large-scale bulk tonnage copper-gold prospect that will be subject to a core drilling program in June 2006.

Assaying was conducted by Acme Laboratories of Vancouver BC and Eco-Tech of Kamloops, BC. All assays for soil and rock are 30 gram fire assays. Field work was under the direction of Dave Kuran, P. Geo., who also compiled and interpreted the data and who is the qualified person for the Company.
