IP Surveys Show Continuation of Anomalies to Depth at El Pulpo

    Vancouver, Canada (ots/PRNewswire) - Ross River Minerals Inc. (TSX-V: RRM) (the "Company") is pleased to  announce results from its Induced Polarity (IP) and magnetometric  geophysical surveys over new grid lines east and west of known porphyry  copper mineralization.  A total of 73.04 line-kilometres of IP and  magnetometer surveys were carried out, including 56.16 line-kilometres east  and 16.88 line-kilometres west of the 2004 grid.  IP geophysical anomalies were detected in the Minitas and Vado Hondo areas (see press releases dated April 25, May 9 and August 11, 2005).

    The IP surveys with a pole-dipole array and a station spacing of 50  metres resulted in IP readings at six depth intervals, corresponding to a  depth of penetration of approximately 150 metres. To obtain a better  understanding of the depth extent of the IP anomalies identified in the  2004 and 2005 IP programs, the Company also re-surveyed 7.54 line- kilometres to a depth of penetration of 12 levels, or approximately 300  metres. The extra depth levels in each case helped to define more clearly  the nature and trend of the chargeability anomalies and associated conductivity/resistivity anomalies.

    The results of the 2004 and 2005 IP surveys clearly indicate a
broad        arc-shaped zone of chargeability anomalies approximately
2.7 by 3.5  kilometres in dimension. This zone extends from the Cerro
Colorado area  north through the Langosta area and west to the Vado
Hondo area. This area  contains porphyry mineralization with
coincident soil and lithogeochemical  anomalies for copper,
molybdenum, silver and gold. The Minitas area (2.5  kms x 1.0 kms) is
characterized by chargeability anomalies, soil anomalies  and
mineralization similar to those of Cerro Colorado approximately two
kilometres to the east.

    The re-survey to 12 depth levels showed that the IP anomalies do extend  at least 300 metres from surface and become stronger with depth. The  positive results from the program have clearly defined drill targets for a drill program scheduled for October.

    James R. Reeves P. Geo was the qualified person supervising the exploration program.
