PRESS RELEASE

MARTIN ZONE DRILLING EXPANDS POTENTIAL Val d’Or, Quebec – July 19, 2011 – Wesdome Gold Mines Ltd (WDO: TSX) (“Wesdome” or the “Company”) is pleased to announce encouraging definition drilling results from the Martin Zone at the producing Kiena Mine Complex, in Val d’Or, Quebec. From the end of February through mid-May of 2011, 27 underground drill holes were completed above the 330 metre level. The drilling covers an area 100 metres high by 180 metres long. The Martin Zone is situated 1.2 kilometres east of the Kiena Shaft (Figure 1). Drifting on the zone, at 330 metres depth, in 2007 demonstrated good continuity, including a section averaging 4.11 gAu/tonne for a length of 91.3 metres across an average drift width of 2.6 metres as determined by composite muck sampling (see Press Release dated May 25, 2007 available at www.wesdome.com). This drilling provides the basis for mine planning work. The zone remains open and is currently being tested above with a surface drill which commenced mid-June. Donovan Pollitt, President, comments “This drilling gives us confidence the Martin Zone has reasonable continuity and room to grow. We look forward to ongoing surface drilling which steps out laterally and above. It doesn’t take much to add significant incremental production to existing mining operations”. Results are tabulated below. Accompanying drawings include a location plan and longitudinal sections showing drill coverage, results to date and planned drilling.
