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 >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 Corp
ABOUT CASCADERO COPPER
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% in 17 properties in the Sudbury, Swayze and Timmins camps, which 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.
