Salta Exploraciones S.A. (Salta), Cascadero's 50% owned Argentine subsidiary, has completed a program of Mobile Metal Ion (MMI) and outcrop rock grab samples in an area adjoining Lumina Copper's 1.762 billion tonne Taca Taca Bajo Cu-Mo-Au deposit. The geochem program was focused on Francisco I, Francisco II and Sarita Este. MAP ONE shows the location of the sample points on each property.


Salta spent eleven days in the Taca Taca Mineral District in late May and early June. The geochemical 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 included 50% owned Francisco I, 50% owned Francisco II and 100% owned Sarita Este. Cascadero Copper owns 50% of Salta.

The Mobile Metal Ion (MMI) geochemical technology was used to detect the presence of sub-surface mineralization in this area. The Company believes that Taca Taca porphyry related mineralization may exist to the west and north west of Lumina Copper's and Salta's property boundaries. In addition, historical sampling and alteration evidence suggest that the Salta properties have high-potential for stand-alone porphyry Cu-Mo-Au, exotic copper, epithermal style gold and IOCG mineralization.

On the Francisco I property, the existing Gold Pit Zone , which historically has produced high-grade copper and gold assays, was revisited and is believed part of a larger structure that trends to the southwest onto Salta's 100% owned La Sarita II property to the west. This zone displays IOCG affinities. A new mineralized zone may be present to the south of the Gold Pit Zone as represented by a train of silica rich boulders. Both of the zones are high-priority showings.

The Francisco II property adjoins Taca Taca immediately to its west and is primarily pediment covered with few outcrops. The MMI sampling was focused on this area as it is close to recent Lumina drill holes and to the common property boundary. This area is also important as it may be on a north western trending channel that may have transported exotic copper from the Taca Taca deposit to the Graben during the leaching process.

On Sarita Este, the gold showing on the property was discovered by Salta in 2006 and confirmed by more sampling in 2008. The recently completed program suggests that a larger area of alteration hosts the original gold discovery. The alteration may be part of larger northwest trending structural and mineralized domain that parallels a regional fault system. Also on Sarita Este, an area of leached cap alteration was discovered on the south eastern part of the property about 600 metres southwest of the Taca Taca deposit.

A follow up exploration program is in the planning stage.

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.

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.
