VANCOUVER, BRITISH COLUMBIA — (Marketwire) — 09/12/12 — Argentum Silver Corp. (TSX VENTURE:ASL) (“Argentum” or the “Company”) has commenced a second phase drilling program at its 1053-hectare Coyote Property in the State of Jalisco, Mexico. The second phase diamond drill program is aimed at demonstrating grade and thickness continuity on the El Tajo vein as well as some scout drilling on the La Colorada and La Valenciana veins. Sixteen drill holes are planned totaling 2,000 metres. Combined, the El Tajo and La Colorada veins have been traced for over a 900 metre strike length on surface. In addition, a new vein system called La Valenciana has been defined approximately 750 metres to the south-west of El Tajo. The La Valenciana vein system is traceable on surface for over 450 metres as a series of exposures and underground workings supported by trenching, geophysics, and soil and rock sampling.

Earlier in 2012, twelve holes were drilled on the El Tajo vein, returning highlights of 2.0 metres of 2,745 g/t Ag and 2.4 meters of 900 g/t Ag, including 1.2 metres of 1,645 g/t Ag. Warren McIntyre, President and CEO of Argentum stated: “The first eleven drill holes of this new program will further test the El Tajo vein and are the next stage in working towards building a future resource at Coyote. The Company is focused on developing shareholder value in its portfolio of properties, with Coyote being our primary focus for the remainder of 2012.”

The program is being supervised by Paul Cowley, P.Geo., the Company’s Senior Geological Consultant and Advisor and a Qualified Person under NI 43-101. Results will be released after being received and interpreted by the Company.

Complete highlights from the previous drilling on Coyote are available in our news releases dated February 29, 2012, March 6, 2012, June 11, 2012 and July 11, 2012.

About the Coyote Property

The 1053-hectare Coyote property contains dozens of individual low sulfidation epithermal silver-gold veins and stockworks. Most of the mineralization occurs within six defined zones within an area of approximately 1.5 x 2.6 kilometres. Vein widths typically range from 1 to over 5 metres. Local areas of stockworks can exceed 35 metres wide. Over 100 historic workings and prospects explored and partially developed the district through the early 1900s. Historic production concentrated on “bonanza” silver grades with operational depth limitations to the high water table.
