Miocene Metals Begins Exploration on Salal, MacKenzie and Rogers Creek Porphyry Projects in South-Western British Columbia

TORONTO, Aug. 11, 2011 /CNW/ - Miocene Metals Limited (TSXV: MII) (the "Company" or "Miocene Metals") today announced that exploration has commenced on its Salal, MacKenzie and Rogers Creek porphyry projects in south-western British Columbia. Project expenditures will be funded by net proceeds of the Company's initial public offering ("IPO"), which was completed on August 5, 2011.  Drilling is expected to commence by August 18, 2011 on the Salal Property

Bruce Jago, President and CEO of Miocene Metals stated "We are very pleased to have completed our IPO, which has provided funding for exploration on these three key projects. The IPO was completed under very difficult market conditions and a negative worldwide economic outlook. Its completion is evidence of the positive exploration potential of our property portfolio all of which are located within three hours drive of the port of Vancouver".

At Salal, up to 3,000 metres of drilling in 10 holes is planned to test surface showings along the 15 kilometre trend of molybdenite occurrences established by historic exploration on the property and confirmed in 2010 by Miocene sampling (see Miocene press release dated August 12, 2010). The 2011 drilling program will focus on defining targets for resource drilling in 2012.

A program of structural mapping and prospecting will start by mid-August on Miocene's MacKenzie copper-gold ("Cu-Au") property, The mapping program is focused on defining one or more structural targets for drill testing.

The MacKenzie Property is located approximately 10 kilometres to the northeast of Salal. Exploration work last year discovered three, north-northwest trending, gently east-dipping, sub-parallel structures, traceable for over a kilometer of strike length. These structures are exposed on a west-facing arcuate cliff, and range from 0.3 metres to 2.5 meters in thickness and consist of gossanous quartz-sulphide veins and massive, siliceous, brecciated lenses of quartz diorite with coarse disseminations and stringers of chalcopyrite, malachite and chalcocite. Results of 2010 sampling of these three parallel structures includes:
 

*Results for samples >~1% Cu and/or 0.1 ppm Au

Permitting is in progress for 2011 drill testing of the Company's gold-copper discovery made on its Rogers Creek property in early July (see Miocene press release dated July 8, 2011). Drilling on the Rogers Creek property is planned to start before the end of September. Up to 1,200 meters of drilling in two holes is planned to test the new discovery. At the same time as drilling, prospecting for similar mineralization will be conducted up-slope from the discovery area within the existing open-ended gold-copper soil anomaly. Additional soil sampling is planned to delineate the up-slope extent of the soil anomaly, which now covers an area of 200 x 800 metres as defined by copper-in-soil values greater than 100 ppm Cu (values greater than 95^th percentile for entire property) against a background of 33 ppm Cu (average of values less than 95% percentile for entire property).
