Vancouver, Canada (ots/PRNewswire) - Ross River Minerals Inc.
(TSX-V: RRM) (the "Company") has received analyses of 34
lithogeochemical samples from the Cetolla area. Copper analyses
ranged from 44.30 ppm Cu to greater than 10,000 ppm Cu (approximately
1%). Four samples exceeded the detection limit of 10,000 ppm Cu.
Molybdenum analytical results ranged from 1.07 ppm Mo to 1,902.64 ppm
Mo. Silver analyses ranged from 116 ppb Ag to 70,701 ppb Ag, with
nine samples exceeding 10,000 ppb, approximately 10 grams per tonne.
Gold analyses ranged from 1 ppb Au to 805.5 ppb Au.
A new road built one kilometre northeast of the Minitas copper
prospect gave improved access to the Jocquistes copper prospect two
kilometres northeast of Minitas as well as the Cetolla prospect three
kilometres north of Minitas. Results have been received for 179
lithogeochemical samples from the Jocquistes area. Three samples
exceeded the detection limit for copper and ten other samples
contained greater than 5,000 ppm Cu. Results for molybdenum ranged
from 0.67 ppm Mo to 1,723.92 ppm Mo. Six samples exceeded 500 ppm Mo
and two of those contained greater than 1,000 ppm Mo. Fourteen
samples contained greater than 10,000 ppb Ag, and one of those
exceeded the detection limit of 100,000 ppb Ag. One sample contained
greater than 1,000 ppb Au, approximately 1 gram per tonne.
In April and May of 2005 prospecting, mapping and sampling was
extended east of the 2004 geophysical and geochemical grid into the
Minitas, Jocquistes and Cetolla areas. A total 77.47 line-kilometres
of soil geochemistry and 56.16 line-kilometres of IP and magnetometer
surveys were carried out over an area of 16 square kilometres.
Disseminated and stockwork copper mineralisation was discovered in
the canyons north of the Minitas copper prospect, which had earlier
detected higher-grade mineralisation related to low-angle quartz
veins and associated phyllic alteration. Subsequent work extended the
disseminated mineralisation northward into the area of a rhyolite
intrusive coincident with an observed increase in molybdenite
mineralisation. Five hundred eighty (580) analytical results have
been received for the lithogeochemical samples taken in this area.
Copper results range from 5.48 ppm Cu to greater than 10,000 ppm Cu.
Twelve samples exceeded the detection limit of 10,000 ppm Cu and an
additional 20 samples exceeded 5,000 ppm Cu. Analytical results for
molybdenum range from 0.51 ppm Mo to greater than 2,000 ppm Mo. Ten
samples exceeded the detection limit of 2,000 ppm Mo and seventeen
samples contained greater than 500 ppm Mo, including seven that
contained greater than 1,000 ppm Mo. Silver results range from 39 ppb
Ag to greater than 100,000 ppb Ag. Nine samples exceeded the
detection limit of 100,000 ppb Ag and 105 other samples contained
greater than 10,000 ppb Ag. Gold analyses range from less than the
detection limit to 7,396 ppb Au, approximately 7.3 grams per tonne.
Nine samples exceeded 1 gram per tonne.
The El Pulpo copper porphyry project, located 125 kilometres
northeast of Mazatlan, Sinaloa State, Mexico, now covers an area of
approximately 40 square kilometres and has five centres of copper
mineralisation - Cerro Colorado, La Langosta, La Cetolla, Jocquistes
and Minitas. The El Pulpo property covers an area of approximately
200 square kilometres of which less than one third has been explored
Analyses were conducted by Acme Laboratories in Vancouver BC. All
samples exceeding the detection limit of the analytical technique
will be reanalysed by techniques appropriate to their higher grades.
