Orosur Mining Inc commences drilling at Mahoma Project, Uruguay
SANTIAGO, Chile, March 5, 2012 – Orosur Mining Inc. (the "Company") (TSX VENTURE: OMI) (LSE: OMI) a South American-focused gold producer and explorer, today announces that it has commenced drilling on its 100 per cent owned Mahoma Project in Uruguay. A programme of approximately 3,000 drill metres comprising 2,000 metres of RC pre-collars and 1,000 metres of diamond drilling is planned.
Orosur has held the property since 2009, however, issues with land access had previously prevented exploration. During the second half of 2011, these issues were resolved and exploration can now be conducted.
The Mahoma Project, previously operated by American Resource Corporation, produced 16,419 ounces (73,431 tonnes at 6.98 g/t Au with 91.6 per cent recovery) between 1993 and 1997. A pre-mining non-compliant NI 43-101 probable reserve of 281,000 tonnes at a diluted grade of 9.36 g/t (15 per cent dilution assumed) was estimated by Watts, Griffis and McOuat.
