EXMIN Identifies Potential Source of Mineralization at the Reyna de Oro Project in the Sierra Madre Gold Belt of Chihuahua, Mexico

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 9, 2005) - EXMIN Resources Inc. (EXMIN) (TSX VENTURE:EXM) is pleased to report that EXMIN's geologic reconnaissance team has discovered the potential source of gold mineralization found at the Reyna de Oro deposit. The team has encountered an area of oxide copper mineralization and a large granodiorite intrusion 2 kilometres to the northeast of the Reyna de Oro deposit, on part of EXMIN's 100% owned, 14,800 hectare concession block that surrounds the Reyna de Oro deposit. The intrusion may indicate the presence of a much larger mineralized system than that contemplated in the original exploration program. This significant development requires the immediate focus of the exploration program. Field crews are currently sampling the area around the intrusive and the area along strike between the intrusive and the Reyna de Oro mine, where EXMIN has conducted 2200 metres of reverse circulation drilling to date. See press releases of May 18, and August 30, 2005.


Drilling at the project to date has focused on the immediate Reyna de Oro mine area to expand the known gold mineralization down dip and along strike. Mapping and sampling around the deposit has traced the mineralized horizon 600 metres to the east and has resulted in the identification of several polymetallic veins (see press release of October 20, 2005). The new discoveries include an area of oxide copper mineralization at La Esmeralda about 1 kilometre northeast of the Reyna de Oro mine (see table below) as well as strongly altered volcanic rocks and identification of copper oxides at the contact with the granodiorite intrusion about 2 kilometres east-northeast of the mine (samples pending). Mineralization elsewhere in the region, such as at the Reforma mine (previously mined by Penoles, S.A. de C.V.), Bahuerachi (Tyler Resources) and Piedras Verdes (Dia Bras), generally consists of intrusion related polymetallic replacements. EXMIN believes that the gold mineralization at the Reyna de Oro deposit is possibly a distal part of a large zoned hydrothermal system.


There is currently no vehicle access to the intrusive and road construction will be extended to the rugged area. EXMIN previously obtained permits for roads and drill sites in the area; about 600 metres of new roads to the north and east of the Reyna de Oro mine have been cut and blasted. The roads will provide access to drill test the eastern extension of mineralization in the same stratigraphic horizon that hosts the Reyna de Oro deposit as well as the new areas to the east. As a result of these very positive developments, the current drill contract announced on October 20, 2005, has been postponed until the preliminary geologic work is completed, drill targets are defined and new roads and drill pads are completed. EXMIN is pleased about the identification of a large mineralized system at the Reyna de Oro project and intends to continue drilling as soon as practicable.


Recent assays of several old, small scale mines and prospects taken at the project imply the presence of a large zoned mineralized system (see table below). To date, areas to the south and southwest of the intrusive body have been sampled, and mineralization has been encountered in andesitic volcanic rocks as well as in a more reactive limestone unit that underlies the volcanic rocks. The samples weigh between 1 and 2.5 kg each and were prepared and analyzed by ALS Chemex at their labs in Chihuahua and Vancouver, respectively.
