Porphyry copper systems show a marked tendency to occur in linear, typically orogen-parallel belts, which range from a few tens to hundreds and even thousands of kilometres long, as exemplified by the Andes of western South America. Cascadero’s Sarita Este epithermal gold bearing high-sulphidation alteration assemblage appears to be perfectly located in an orogenic belt partly in eastern Chile and partly in western Argentina. This belt is ~ 500 miles in strike is densely populated with large-scale, Giant and Super Giant copper and gold deposits.

The aphorism Location-Location-Location is well known in urban and commercial Real Estate. It clearly applies to the porphyry model as stated and outlined above. Porphyry deposits occur in clusters and frequently with a linear country - scale structure, controlling the location of the deposits.

Gold-rich porphyry deposits worldwide conform well to a generalized descriptive model. This model incorporates six main facies of hydrothermal alteration and mineralization which are zoned upward and outward with respect to composite porphyry stocks of cylindrical nature that form atop much larger parent plutons. This intrusive environment and its overlying advanced argillic lithocap span about 4 kms vertically, an interval over which profound changes in the style and mineralogy of gold and associated copper mineralisation are observed.

The model predicts several geological attributes to be expected in association with superior gold-rich porphyry deposits. Management believes that recent ground-based geochemistry, field observations and thin section work have provided a detailed description of the minerals and alteration that have focused the Company on Sarita Este as a potential large-scale gold-rich porphyry prospect. 

Exploration for gold-rich porphyry deposits worldwide involves geologic, geochemical and geophysical work, but generally employs the descriptive model in an unsophisticated manner and the genetic model rarely. Discovery of gold-rich porphyry deposits during the last 30 years has resulted mainly from basic geologic observations and conventional geochemical surveys. A gold-rich porphyry is described as a deposit that averages >3 g/t Au.  The tried-and-tested approach is thought likely to provide for the foreseeable future although more rigorous application of the descriptive and genetic model can only improve the chances of success. (Excerpt from R. Sillitoe 2000)

Argentina has had significantly less exploration activity than Chile because of previous government regulations and we believe this will enable a going forward high - frequency of discoveries in Argentina as the geological setting has some similarities to eastern Chile.  Cascadero’s property portfolio holds high-potential properties in the right areas at the right time. Sarita Este is permitted to the trench stage and we expect work to get underway in late spring.
