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. MAP ONE illustrates the Chilean and Argentine Porphyry

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.
