CALGARY, May 29 /CNW/ - Sienna Gold Inc. (SGP TSX Venture Exchange) announces that it has completed 2 additional drill holes on the Igor property. A summary of the 146.8 meter hole 9d is shown below. The hole was collared at elevation 3188 and drilled obliquely to the strike of the breccia zone at an inclination of -35 degrees from the horizontal. It entered the breccia zone at elevation 3166 and penetrated a true thickness of approximately 42 meters.

This hole confirms the existence of mineralization to the north of the areas previously sampled and the Company is currently doing step-out drilling through an ancient landslide further to the north. This hole was drilled 15 meters past the breccia zone into the Chicama Formation and the average grade of this material was over 0.2 gpt Au. A summary of the 112.8 meter hole number 9c is shown on the table below. The hole was collared at elevation 3232 and drilled approximately perpendicular to the breccia at an inclination of -70 degrees from the horizontal. It entered the breccia zone at elevation 3170 and penetrated a true thickness of approximately 10.6 meters of mineralization.

The 9a,b,c,d series of drill holes were drilled to cross cut the Tesoros breccia zone at increasing depths. Hole 9a cross cut the breccia zone below the 3120 mine workings level. Holes 9b and 9c cross cut the breccia zone between the 3120 and 3150 mine workings levels. Hole 9d cross cut the breccia zone between the 3150 level and the Randy 2 and 3 cross cut workings. Now that the Tesoros breccia zone has been cross cut at five successive elevations, Sienna's geologists are able to subdivide the Tesoros breccia zone into alteration/mineralization zones typical of sediment-hosted, structural controlled, high sulfidation, epithermal, mineralized systems. Holes 9a, b and c cross cut the Tesoros breccia in the lower distal zone where widths are in the 10 to 15m range and grades are similar to those announced. Hole 9d and the Randy 2 and 3 cross cut workings cut the Tesoros breccia zone in the zone of boiling, where widths and grades are typically 2 to 3 times more than those encountered in the lower distal zones of these types of epithermal systems. The Company's drill results lend credence to this geologic model. The down dip width and grade relationships of the breccia zone are now better understood. This will allow near term exploration drilling to focus on discovering strike extensions to the north and down dip extensions to the south of the outcropping, central Tesoros breccia zone. Anomalous copper, lead and zinc assays in the drill hole samples gives added weight to the Company's belief in the existence of a mineralized, underlying porphyry system.
Sampling Methodology
Cores taken from the diamond drill rig are stored in plastic core boxes and transported to the camp site for detailed logging. When logged the core is sent from the project site to the Company's secured site in Trujillo for splitting with a diamond saw. One half of the split core is then sent to an accredited laboratory in two meter sample lengths. The Company's independent, qualified person has completed a chain of custody review to ensure the integrity of all sample data.
Assaying Methodology
The samples are analyzed by an accredited laboratory in Lima by atomic absorption for silver 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. Blank samples are randomly inserted into the sample runs and referee assays are done on randomly selected samples to confirm the laboratory results. The specific procedures used by the lab can be found in the company's 43-101 report on the Igor property.
