Marengo Mining Limited ("Marengo" or the "Company") announces commencement of a planned diamond drilling campaign, of approximately 2000 metres, targeting the Dimbi zone of the Yandera Central Porphyry System.

A drill rig is currently being mobilised to site with drilling scheduled to commence on or about 13 September 2013, with completion of the ten hole program planned by the end of the 2013 field season, in early December.

The exploration strategy is to identify near surface resources that may enhance a starter pit for a Yandera mining operation. The drill holes will target recently mapped mineralised structures, of which six holes will jointly test updip projections of elevated copper intercepts in existing drill holes.

Due to the challenging terrain, the Dimbi zone has received less attention as an exploration target than the other zones (Gremi, Imbruminda and Omora) that make up the Yandera Central Porphyry System. As a result, a detailed field mapping program was mounted in mid-2013, to improve the geological understanding of the Dimbi zone, the rock types, and especially the nature, extent and orientation of recently identified, outcropping mineralised structures.

A fundamental north-westerly striking structure, the Dimbi Fault, which dips at a high angle to the north-east, bounds the Dimbi zone on the south–west. This early fault established a conduit for mineralised fluid flow into the Dimbi zone, along a later set of north-east trending faults. Drill holes have been sited to test projections of interpreted north-east striking mineralised structures in the hanging wall of the Dimbi Fault, as well as elevated copper intercepts in several nearby existing holes.

An elongated copper-in-soil geochemical anomaly runs parallel to, and overlies the hanging wall of the Dimbi Fault, reinforcing the logic of this current drilling strategy.

Yandera Feasibility Study

Marengo continues to work towards completion of a feasibility study on the Yandera Project. In these efforts a continuing focus is on identifying the most efficient and cost effective power solution, together with reviewing the options for environmentally responsible disposal of mine tailings.

Cash Reserves

As at June 30, 2013, the Company had cash reserves of US$6.7 million.

On August 12, 2013, Marengo announced the closing of the third and final tranche of a Debenture issue which generated an additional US$6.0 million.
