CALGARY, Aug. 31 /CNW/ - Sienna Gold Inc. (SGP TSX Venture Exchange) announces the latest significant assay results from the Igor property. The Domo 1 area sampled consists of a 225 meter long tunnel into the lowest of three mantos or beds. These assays are from 140 samples taken from the first of 7 tunnels opened by previous owners of the property. Based on exploration to-date at the Igor property, it is known that high concentrations of gold and silver are found in areas of tight anticlinal folding which is characteristic of the Domo zone. The three, approximately 1 meter thick mantos in the Domo zone are subparallel shale beds which trapped the hydrothermal fluids during mineralization sequences. The host rocks are composed of Chimu sandstones. Both the sandstone host and the shale mantos are webbed with quartz veinlets orientated perpendicular to the bedding planes of the sedimentary rocks. The density of occurrence of the veinlets determines the grade of the material. The thickness of the mineralized material is unknown at this time but the distance from the bottom manto to the topographic surface is 30 to 50 meters. There is no waste material overlying the Domo zone. The Domo zone extends over an area of approximately 700 meters by 100 meters and the results reported in this press release are from the stratigraphically and topographically lowest manto which is located approximately 750 meters northwest and 400 meters above the Tesoros breccia zone. The samples were taken from channel rings every 6 meters along the tunnel as described below.

The average lead assay in the samples was 0.5% with a maximum value of 4.4%. Pathfinder minerals, bismuth and antimony, were also very high with 10 samples assaying over 1%. The results of these assays confirms to the Company the need to drill the Domo area. The Company has commenced procedures to obtain government drilling permits.
Following is a listing of the most significant sample assays received.

Sampling Methodology
The samples were taken by first exposing fresh rock in a 15 centimetre wide by 2 centimetre deep channel forming a ring in the walls and roof perpendicular to the axis of the tunnel and located every 6 meters along the tunnel. Continuous samples within specific lithologies were then chipped from the full width of the channel and collected for analysis. Where the rock was too hard for a full width sample, a narrower sample was taken from within the prepared channel zone ensuring that samples from the full with of the channel were obtained.
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.
