Cascadero Copper Corporation (TSX VENTURE:CCD) -
Salta Exploraciones S.A. (Salta), Cascadero's 50% owned
Argentine subsidiary, has received a NI 43-101 Technical Report
prepared by Ruth Bezys and Mark Fedikow, who compiled and
interpreted the recent Mobile Metal Ion (MMI) soil geochemical data
from a program on the Incahuasi Cu-Mo-Au porphyry prospect in Salta
province, north western Argentina. Salta geologists collected 43
MMI samples in the pediment within the area of the 2010
IP/Resistivity/Magnetic geophysical grid. The sampling program was
operated by Salta geologists and personnel and designed and
supervised by Raul Chocobar, vice-president of exploration and a
director of Salta. Samples were assayed by SGS Peru.
The Interpretation and Conclusions of the report are:
The main commodity element response on the Incahuasi property is
a multi-metal and multi-sample response that is both focused and
low-to-high contrast. This anomaly occurs in one main area of the
sampling grid, a northeast zone of Cu-Ag-Au with long axis
dimensions greater than 750m. This anomaly remains open to the
northeast.
The Cu-Au-Ag anomaly is closely abutted (with some overlap) by
the Pb-Zn anomaly and this offset is interpreted as bedrock-hosted
metal zonation, the likes of which are to be expected from metal
deposition in an evolving hydrothermal system.
The magnitude of the commodity element responses is generally
low-to-moderate contrast, which is consistent with a
disseminated-style of bulk minable mineralization.
In late 2010, a geophysical survey was conducted on the
Incahuasi prospect, which included a ground magnetic survey on N-S
lines spaced 50m apart for a total of 566 line km. The IP data were
acquired with a pole-dipole array, a dipole spacing of 100m and
consisted of 12 lines at 400m line spacing totaling 75.6 line km.
The ground magnetic data define a large, broad magnetic-low
measuring over 3,000m in diameter. This magnetic-low is tentatively
interpreted as the geophysical signature of a large hydrothermal
alteration system. Several strong magnetic-highs occur within the
broad magnetic-low.
Strong IP anomalies are outlined at Incahuasi. The amplitude of
the chargeability exceeds 50 mV/V on multiple lines and reaches 88
mV/V on Line 207100E. The strong chargeability anomaly is located
mostly within the pediment and is approximately 3 km in length and
400m to 800m wide. The strong chargeability anomaly is coincident
with a conductive zone. The most conductive areas correlate with
the highest chargeabilities and also the strong magnetic-high.
A second chargeability anomaly is located to the southwest of
the primary anomaly. The southwest extension is located in the
hills, outside of the main valley. The chargeabilities are somewhat
lower (20 to 35 mV/V) and are also associated with
lower-resistivities and a weak to moderate magnetic-high. The
geophysical data appear to map a large, complex hydrothermal
alteration system at Incahuasi.
There are a few outcrops in the Incahuasi pediment area and all
have mineralization and alteration assemblages characteristic of
mineralized porphyry systems. In addition, there are several areas
of copper, gold and molybdenum mineralized veins and stockwork that
surround the pediment and these may represent leakage from a buried
Cu-Mo-Au porphyry system.
The authors of the Technical Report have recommendations for
further work as follows:
Prior to diamond drill testing, the MMI dataset should be
integrated with all available geophysical and geological survey
data so that multivariate drill targets can be determined for
future drill testing.
Additional MMI surveys are recommended to the north and
northeast of the present survey grid to truncate and assess the
multi-element anomalies; the same sampling and analytical protocols
should be utilized for these surveys.
It is also recommended that field duplicates be collected for
every 50th sample or a minimum of one per-sample batch and that the
SGS laboratory in Lima report the results of standard reference
materials used to bracket MMI analyses of samples.
Incahuasi is the most southerly of three Pancho Arias District
porphyry prospects, which include Las Burras, which is 4km to the
northeast of Incahuasi and Pancho Arias, which is 9 kms north of
Las Burras. Salta is preparing a 4 to 6 core hole program on Pancho
Arias to test some of the historic drilling and to drill new
targets. The drill will be moved to the previously undrilled
Incahuasi showing and 4 to 6 reconnaissance style core holes are
planned.
The Company is excited by the opportunity that the Pancho Arias
District porphyries provide. Each system has a large-scale
geophysical footprint and excellent surface geochemistry. Pancho
Arias is a copper-molybdenum deposit as indicated by the presence
of Cu-Mo mineralization in 10 historic drill holes. The relative
location of the three intrusions is controlled by a common
northeast trending district-scale fault system, which is cut by
northwest trending regional fractures. Each is believed to have the
same middle Miocene-aged magmatic origin.
In May 2011, Salta drilled 4 core holes, in section, across the
northern part of the Las Burras geophysical and MMI geochemical
anomaly. Each core hole contained Cu-Mo-Au mineralization in
porphyritic granodiorite from surface to total depth. The first
three holes bottomed in Cu-Mo-Au mineralization at 300 metres. The
fourth hole LB11-04, is collared on the western most part of the
chargeability anomaly and has a lower tenure of Cu-Mo-Au
mineralization. The core hole was lost in a fault before total
depth was attained.
The showings are closely spaced and each has the potential to
host a mid-to-large tonnage Cu-Mo-Au mineralized porphyry system.
The proximity of the showings and the combined potential tonnage
could be of interest to most global mining companies in the copper
space.
The Pancho Arias District is a region with exceptional
infrastructure, including surface water, a railway to the Pacific
Ocean Port of Antofagasta, a high-tension power line and National
Highway 51 are all located within a few kilometres of the porphyry
showings.
The geochemical data portion of this news release was read and
approved by Ruth Bezys and Mark Fedikow who are the Qualified
Persons for the Company. Assaying was done by SGS Lima, Peru.

Cascadero Copper is an integrated prospecting and mineral
exploration business with offices in North Vancouver, BC, Canada,
Sudbury, Ontario, Canada and Salta City in the province of Salta,
Republic of Argentina. The Company generates, acquires and explores
mineral properties and is active in the three jurisdictions.
In north central British Columbia, the Company has a 100%
interest in a 31,000 hectare property in the Toodoggone region,
which is prospective for copper gold porphyry systems. This
property is subject to a C$20 million Joint Venture with Gold
Fields. Exploration should get underway by June 2012.
In Ontario, the Company holds or has the right to acquire a 100%

are volcanic and sediment hosted copper and gold prospects.
In north western Argentina, the Company holds a 50% interest in
a 46 property portfolio, which consists mainly of bulk mineable
copper-moly-gold porphyries and bulk mineable sediment hosted
epithermal silver-gold plus base prospects.
In 2009, the Company discovered Taron, a potentially large bulk
mineable sediment hosted epithermal rare metal deposit in
Argentina. In 2011, Cascadero discovered Las Burras, a new
Argentine Cu-Mo-Au porphyry.
Cascadero's commodity focus is gold, silver, moly, copper and
base and rare metal deposits, which are hosted in bulk mineable
mineral systems.
In 2012 to 2013, Cascadero intends to advance by drilling three
Argentine Cu-Mo-Au porphyry systems and continue development work
in the El Oculto District, which has high potential to host
high-grade bulk mineable silver-rich systems. Exploration is also
planned for Taron, an exciting large-scale sediment hosted rare
metal discovery.
