Vancouver, Canada (ots/PRNewswire)
- Ross River Minerals Inc.
(TSX-V: RRM) (the "Company") is pleased to announce that copper
porphyry style mineralization discovered at Minitas (see press
release dated April 25, 2005) has now been extended by geological
mapping, prospecting and Induced Polarization (I.P.) geophysics to
cover a northwest to southeast trending area that is at least 2,500
metres in length by 950 metres width in a northeast by southwest
direction. Within this defined area are zones of varying intensities
of phyllic alteration overprinting potassic alteration
(biotite-potassic feldspar). Peripheral and outside this area are
zones of propylitic alteration overprinting potassic alteration.
Porphyry style mineralization within and peripheral to this area,
extending over a vertical distance of at least 90 metres, is
exhibited by pyrite-chalcopyrite or their leached equivalents
occurring within stockwork and near vertical sheeted quartz veinlets
or as disseminations within the altered intrusive granodiorite. The
mineralization is open at depth. A total of 583 soil geochemical
samples and 287 surface rock samples have been shipped for analyses.
The volume of alteration and scale of mineralization indicates that
there has been significant hydrothermal fluid movement within this
part of the intrusive. Trenching and more systematic rock sampling is
now being carried out within the Minitas area.
Prospecting is also being carried out one kilometre northeast of
Minitas where sheeted and stockwork quartz-molybdenite veining and
disseminated chalcopyrite has been discovered.
The El Pulpo copper-gold porphyry project now extends over a
distance of 7.0 kilometres in a northeast to southwest direction and
5.5 kilometres in a northwest to southeast direction. There are five
centres of copper mineralization - Cerro Colorado (1,900 x 750
metres), La Langosta (1,800 x 1,050 metres), La Cetolla (1,100 x 230
metres), Jocquistes (1,000 x 750 metres) and Minitas (2,500 x 950
metres) occurring peripherally to a core zone with quartz-molybdenite
mineralization which has yet to be fully explored. The La Cetolla and
Jocquistes prospects have not been fully delineated. This geological
setting is typical of many copper porphyry districts occurring
worldwide. The project is being supervised by James R. Reeves M.Sc.,
