Salta Exploraciones S.A. (Salta), Cascadero's 50% owned Argentine subsidiary, has completed a follow up program of geochemical sampling on the 100% owned Sarita Este gold prospect. The gold showing on the property was discovered by Salta in 2006 and confirmed by more sampling in 2008. The recently completed program confirms that the gold showing is part of northwest trending structure and alteration zone. The gold values occur over an area about 800 metres north south by up to 500 metres east west. The assay results from 35 new samples are reported in TABLE ONE below.

TABLE ONE assays confirm the presence of significantly higher-grade gold in subcrop and outcrop over a larger area than the 63 assays that were taken in 2006 to 2008. Of the 2006 to 2008 samples, 10 were above 1.0 g/t gold with the highest at 36.5 g/t gold (1.2 oz/tn). The current program included trenches that exposed more subcrop with mineralized areas of quartz veins, veinlets, and stockwork that have strong limonitic alteration. The mineralized array is hosted by a volcanic assemblage consisting of tuffs and sediments. The geological setting and the relationship of the gold showing to the Taca Bajo deposit is unclear. Pyrite occurs in some of the samples and elevated levels of copper are present.

The fire assay gold values are very high and ACME duplicated and repeated several samples. The ACME Labs ICP assays in parts per billion (ppb) are higher than the fire assays. The average weight of the 35 samples is 1.1 kgs.

Sarita Este adjoins Lumina Copper's claim group that hosts the 1.762 billion tonne Taca Bajo Cu-Mo-Au deposit immediately to its west. Sarita Este also adjoins the southern boundary of the 50% owned Francisco II prospect where Lumina has encountered good copper grade over significant widths close to the Francisco II and Taca Bajo common border. In addition, an area of leached cap alteration is present on the southeastern part of the property about 600 metres southwest of the Taca Bajo deposit. A follow up exploration program consisting of trenching mapping and sampling is in the planning stage on both the high-grade gold showing and the large area of porphyry style alteration.


Salta spent eleven days geochemical sampling in the Taca Taca Mineral District in late May and early June. The program was designed by Salta Exploraciones (Salta). The field work was performed and managed by Ron Bilquist Salta VP of Operations, with Salta field assistants and a locally contracted backhoe with operator. The properties sampled are the 50% owned Francisco I, 50% owned Francisco II and 100% owned Sarita Este.

All samples from the Sarita Este program are prepared by Salta Exploraciones and delivered by truck to ACME Labs in Mendoza, Argentina for preparation and then shipped to ACME Labs Santiago, Chile then by air freight to ACME Labs Vancouver B.C. for ICP assay.

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, who is currently core drilling the MEX Cu-Au porphyry system.

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 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 silver-gold plus base and rare metals.

Cascadero's commodity focus is gold, silver, moly, copper, base and rare metal hosted in large-scale bulk mineable mineral systems.

In 2009, the Company discovered Taron, a large bulk mineable sediment hosted epithermal rare metal deposit in Argentina. In 2011, Cascadero discovered Las Burras, a new Argentine Cu-Mo-Au porphyry.

The Company holds a large claim block that adjoins Lumina Copper's Taca Taca Bajo Cu-Mo-Au deposit. Several copper and gold showings exist on these claims. A first stage geochemical program is complete.

In 2012 to 2013, Cascadero intends to conduct exploration in three core areas: Pancho Arias Cu-Mo-Au porphyry District, the Taca Taca Mineral District and the bulk mineable sediment hosted silver prospects in the El Oculto District. Exploration is also planned for Taron, an exciting large-scale sediment hosted rare metal discovery.
