New Porphyry Discovery at El Pulpo

Vancouver, Canada (ots/PRNewswire)

Ross River Minerals Inc.
(TSX-V: RRM) (the "Company") is pleased to  report that while
investigating a high-grade copper vein occurrence two  kilometres
southeast of its Cerro Colorado copper-gold porphyry target on  Ross
River's El Pulpo property, geologists have discovered new porphyry-
style copper mineralization occurring in deep arroyos cutting through
a  potassicaly altered phase of intrusive rock of the Sinaloa
batholith. The  mineralization exposed in arroyos consists of
chalcopyrite or leached  equivalents occurring in stockwork veinlets
and disseminations extending at  least 30 metres vertically below the
shallow-dipping quartz veins.  Mineralization has been encountered
over an area of approximately 750  metres in a north-south direction
by 850 metres in an east-west direction  and is open in all
directions. This new area, named the Minitas prospect,  is over 1,000
metres east of the 2004 surveyed grid and is included in the
easterly extension of the soil geochemical and geophysical survey
currently  being conducted. Soil geochemistry on 200 metre spaced
grid lines over the  Minitas prospect has recently been completed and
shipped for analyses. In  addition 213 rock samples have also been
shipped for analyses. Induced  Polarization (I.P.) geophysics over
the area is scheduled shortly.
In the western part of the El Pulpo Property, I.P. geophysics has
closed off the anomaly near the village of Vado Hondo to the west and
east.  This chargeability anomaly which ranges from over 7
milliseconds at the  western extremity increases in size and strength
to over 10 milliseconds  800 metres to the east where it merges into
the anomalous zone encountered  in 2004 east of Vado Hondo, ranging
from 10 to over 28 milliseconds at N( equal sign)6 (approximately 150
metres depth). This zone is 600 metres wide  in a north-south
direction. Within the newly surveyed area chargeability  values at
N(equal sign)4 (corresponding to about 100 metres depth) greater
than 15 milliseconds outline an area 600 metres in a north-south
direction  and up to 350 metres wide in an east-west direction.
Some of the higher I.P. anomalies extend to depth and are open and
beyond the capacity of the current I.P. equipment in use. Ross River
is  viewing alternatives to extend the depth range of the I.P.
geophysics as  several anomalies including Cerro Colorado are open at
depth. The 2005  exploration program is being carried out under the
direction of James R.  Reeves M.Sc, P.Geo.
