12 Month Share Price Performance

• Highly Prospective Projects

  • Niuminco is currently focused on its gold projects including highly prospective properties adjacent or close to existing large mines or deposits, including PanAust's +18Moz AuEq Frieda River deposit and Harmony/ Newcrest's Hidden Valley Mine, which produced ~190Koz of AuEq in 2015.

  • Niuminco, through its 72.54% shareholding in TNT Mines Limited, controls and manages a suite of advanced exploration assets highly prospective for tin and tungsten in Tasmania, Australia.

• Growing Gold and Silver Production

  • Niuminco owns and operates a gold and silver mine at its Edie Creek project which has significant infrastructure in place.

  • Niuminco is positioning itself to increase throughput of ore through its plant by over 600% from 6.0tpd to over 40tpd. With minimal fixed operating overheads, the increase in plant throughput is expected to significantly increase revenues to the Company, with attractive margins.

• Near-Term Exploration Upside

  • Niuminco's gold projects remain highly underexplored.

  • Niuminco is currently drill testing at its operating mine, Edie Creek, to delineate a maiden JORC Resource and to test for extensions of known vein and lode systems, as well as bulk tonnage targets.

  • Niuminco has completed limited exploration on its May River and Bolobip projects since over $6.7 million was spent on exploration activities during 2011 - 2013. Niuminco is now planning to follow up identified targets through two drilling programmes.
