CALGARY, April 26 /CNW/ - Sienna Gold Inc. (SGP.V TSX Venture Exchange) reports the results of its latest soil, trench and rock sampling program. This program was designed to test the potential for porphyry gold-copper mineralization at Igor, following the recognition in 2006 of widespread classic porphyry-style (phyllic) alteration and of porphyry intrusions. Previously the potential was thought to be entirely hosted by structures, such as the Tesoros Zone, drilled in 2006.
Results received so far confirm the presence of mineralized porphyry intrusions over a strike length of at least 2 km. A 48 meter trench across one porphyry outcrop resulted in an average of 1.2 grams per tonne of gold. A 15 meter interval within the trench averaged 2.2 grams per tonne of gold.
The geochemical pathfinder elements for gold are also strongly anomalous over a strike length of more than two kilometres. An unusually strong molybdenum anomaly, with values up to 0.07% Mo, occurs on the ridge axis at Igor (Domo). This may point to the strongly mineralized core of a gold-copper porphyry system. All these features are viewed as very positive.
Continued soil, trench and rock sampling is being undertaken. This work will fill in data gaps and is expected to extend mineralization. The company has drill permits and expects to test the geochemical anomalies within 3 months.
Sampling Methodology
Rock chip, channel and soil samples were taken at regular intervals along pre-determined sampling lines. Complete descriptions of the samples were recorded (rock type, alteration, structure, mineralization) and the samples were sent for geochemical analysis.
Assaying Methodology
The samples were analyzed by ALS Chemx Laboratories in Lima by inductively coupled plasma atomic emission spectroscopy ("ICP-AES") analysis for silver and 33 other elements and a 30 gram fire assay technique for the gold analysis. Samples which exceeded the detection limits were re-assayed using a gravimetric fire assay technique. The specific procedures used by the lab can be found in the company's 43-101 report on the Igor property.
Sienna Gold Inc. continues to explore in Peru for precious and base metals. Its major projects are Igor and Pachin Alto which are the focus of the Company's activities.
