Marengo Announces Further High Grade Copper-Molybdenum-Gold Results From the Yandera Project (PNG) Drilling

PERTH, WESTERN AUSTRALIA--(Marketwire - Oct. 17, 2012) - Marengo Mining Limited (ASX:MGO)(POMSoX:MGO)(TSX:MRN) -



Results from ongoing diamond drilling at the Yandera Copper-Molybdenum-Gold Project continue to generate high-grade mineralisation from three of the resource zones;

  • Omora Zone:
    • 165 metres @ 1.08% Cu, 381 ppm Mo
      (including 66 metres @ 1.80% Cu, 574 ppm Mo)
  • Gremi Zone:
    • 186 metres @ 0.89% Cu, 232 ppm Mo
  • Imbruminda Zone:
    • 270 metres @ 0.80% Cu, 264 ppm Mo, 0.58% g/t Au
      (including 90 metres @ 1.73% Cu, 585 ppm Mo, 0.51% g/t Au)

Marengo Mining Limited (ASX:MGO)(POMSoX:MGO)(TSX:MRN) ("Marengo" or the "Company") is pleased to announce further high grade intercepts from its ongoing infill program at the Yandera Cu-Mo-Au project. The following data will be included in the mine planning, being undertaken as part of Marengo Mining's Feasibility Study, which is nearing completion.

The results provide further strong evidence of the presence of high-grade zones, which are expected to enhance revenues and cash flows from mining in the early years of the targeted 20 year operations at Yandera.
