Ochaqui Silver
The writer was asked by Bill McWilliam, CEO of Cascadero Copper, to review the data on the Ochaqui Silver (Incamayo Sur) property. To that end, I acquired all the prospecting data from prospector Ron Bilquist and talked to him by phone about his impressions of the property. I have not visited the property however, I have worked extensively in this part of Argentina. I have examined similar properties in Salta, Catamarca and San Juan provinces in Argentina and similar mineralized systems in Chile, Peru, Colombia, Mexico and Nevada, USA. I have worked with Ron Bilquist in the field and have a high regard for his ability.
The Ochaqui property is located at the eastern edge of the Argentine 'puna' about 100 km west of Salta city and roughly 10 km south of the Incamayo property. The concession measures 3,440 hectares in size and covers the western slopes of a north - trending ridge between 4,000 and 4,600 metres elevation. The area is dry, semi-desert with no vegetation. At present the property is not road accessible but is located about 12 km from an existing road to the Incamayo property.
The property is underlain by clastic metasediments which are probably similar to the host rocks at Incamayo property. A prominent color anomaly (gossan) on the western slopes outlines one or more mineralized zones at least 50 to 100 metres wide which could extend 4 km or more along strike. It is possible that the mineralized zone(s) could be wider as the western extent is masked by base-of-slope talus or pediment cover.
A total of 146 rock samples were collected by the prospectors during their examination of the property. Of these, 55 are anomalous in silver to a maximum of +100 g/t (+3 oz/ton). A number of these samples are also anomalous in gold (to 2.6 g/t), copper (to 1145 ppm), lead (to 0.90%), zinc (to + 1.0%), antimony (to + 2000 PPM), as well as bismuth, arsenic, barium and mercury. The mineralization appears to be localized in silicified breccias and areas of quartz stockwork.
The setting, style of mineralization and patterns of anomalous metals are characteristic of high-sulphidation, epithermal precious metal deposits, similar to the Incamayo property to the north. Differences in silver content and lower values in copper could indicate that outcropping mineralization is at a higher level in the system. The zones could be wider and have a greater areal extent than the Incamayo showings and hence have greater potential for the discovery of a bulk tonnage silver deposit.
It is recommended that a more detailed prospecting and mapping program be completed and followed up by trenching of the exposed mineralized zones and possible extensions. Consideration should be given to expanding the claim block to cover possible extensions (to the south?) as indicated by the prospector's report.
