CALGARY, ALBERTA–(Marketwire – June 26, 2012) - Sienna Gold Inc. ("Sienna" or the "Company") (TSX VENTURE:SGP)(LMA:SGP) is pleased to announce the latest results from new drill holes at Callanquitas, on the Igor project, La Libertad, Peru. The two holes totalled 512 meters (m).
Drill Hole Results
The results are from Holes CA-12-41 and CA-12-42. Both holes cut several mineralized structures.
The best results from Hole CA-12-41 were 1.4 m at 9.7 g/t gold and 1864.1 g/t silver. This intercept is part of a longer high grade interval, 5.4 m at 3.4 grams/tonne (g/t) gold and 520.5 g/t silver, within an overall 11.1 m at 1.9 g/t gold and 272.8 g/t silver.
Drill hole CA-12-42 also returned excellent results with two significant high grade zones within a broad mineralized interval: 3.6 m at 2.0 g/t gold and 38.4 g/t silver and 6.5 m at 5.5 g/t gold and 21.1 g/t silver within a 41.5 m interval at 1.3 g/t gold and 8.1 g/t silver. Full results are given in the table below.
Drill hole CA-12-41 is from the East – West section N4281 while Hole CA-12-42 is from the oblique section NW4750. A map showing the locations of these holes is presented below as is Section N4281. Further maps and cross sections are available on the Sienna Gold website.

The Callanquitas Structure
Dr. Owen Miller, Exploration Manager of Sienna Gold, comments, "These latest drill holes continue the excellent results from the Callanquitas drill program.
The mineralization on Section N4281 is present over a vertical interval of 270 m and is open at depth.
It is of particular interest as this is the second time we have intercepted very high grade gold and silver mineralization at the southern end of the Callanquitas structure. Hole CA-12-21 located on section N4233, some 50 m to the south, also returned high grade gold and silver values (See press release dated 28 February, 2012).
Due to the success of the Callanquitas drilling the original 10,000 m program for Callanquitas has been extended to between 13,000 and 14,000 m.
The objective is still to define the first inferred resource for Callanquitas before the end of the year."

1It should be noted that these are all angled holes and downhole intervals do not necessarily reflect the true width of the mineralized structure.
2 Weighted averages were calculated for continuously mineralized intervals using a bottom cut on 0.1 – 0.2 g/t gold, no top cut and minimum internal waste.
3 This interval contains a 1.7 m zone of no recovery.
A full list of drill holes and significant intercepts is available on the website: www.siennagold.com.
Two rigs continue on site: one large tracked rig and a man portable rig. A total of 11,500 m has been drilled to date. As mentioned above the current campaign will now be at least 13,000-14,000 m for Callanquitas.
A new NI 43-101 resource calculation is planned for late 2012.
Rehabilitation of access roads and initial mapping and sampling has started at Domo and Tesoro. Drilling is scheduled for later in the year.
Cores taken from the diamond drill rig are stored in plastic core boxes and transported to the camp for detailed logging. Afterwards, the core is cut on site with a diamond saw.
One half is then sent to an accredited laboratory in various sample lengths. William R. Henkle (PGeol), the Company's independent Qualified Person, completed a chain of custody review to ensure the integrity of all sample data.
The samples are analysed by SGS Laboratories in Lima by inductively coupled plasma atomic emission spectroscopy for silver and 37 other elements (included Hg and Te) and a 30 gram fire assay technique for gold. Samples above detection limits are re-assayed using a gravimetric fire assay. The specific lab procedures can be found in the Company's 43-101 report on the Igor property.
This press release was reviewed and approved by William R. Henkle P.Geol who is a "Qualified Person" according to National Instrument 43-101.
On Friday June 22, 2012 the Company closed the first tranche of the private placement announced on June 5, 2012 in the amount of $2,011,299.65 US. The Company paid a 7% commission in cash and broker warrants to qualified investment dealers. These funds will be utilized for continued exploration on Callanquitas, and general working capital. Securities issued on this closing carry trading restrictions until October 23, 2012.
Sienna Gold Inc. is a gold exploration company with property interests in Peru. Its key prospect is the Igor Mine Project, a formerly producing mine that the Corporation plans to explore further.
