Robinson Range Iron Ore Project

Summary

  • Potential exists for Iron Ore deposits within the Robinson Range Banded Iron Formation in the southern part of Peak Hill Mineral Field.
  • The potential Iron Ore deposits have grades of up to 65% Fe with low phosphorous content.
  • Under a farm-in and joint venture agreement PepinNini Minerals Limited has earned a 50% right to the iron ore potential contained within three tenements and a 40% right in four tenements held by Grosvenor Gold Pty Ltd covering approximately 700sqkms in the Robinson Range area of Western Australia.
  • Limited exploration undertaken in 1970′s for iron ore identified up to 200 small patches of iron ore with grades of up to 65% Fe overlying the iron formations in Robinson Range.
  • Rock Chip samples have returned grades up to 67% Fe with low phosphorous contents.
  • PepinNini Minerals has identified approximately 40 kms strike length of the prospective Robinson Range Formation within the JV tenements and has completed a detailed 250m grid gravity survey and a detailed surface mapping and sampling program.
  • Joint Venture Agreements have been executed to facilitate the exploration and development of the identified Direct Shipping Ore (DSO) potential of the tenements.
  • PepinNini manage exploration on behalf of the Joint Venture.

The Joint Venture is currently focused on exploration of the identified Direct Shipping Ore (DSO) potential of the tenements. During 2011 and 2012 PepinNini undertook an extensive reverse circulation (RC) drilling program designed to investigate potential supergene iron ore resources at eleven prospect areas located amongst the ~40km strike length of Robinson Range Formation identified within the project area. Ninety eight boreholes were completed for 5,609 metres of drilling.

Encouraging hematite, hematite-goethite iron enrichment was encountered at PNN Area C. Highlights include;

  • 24 metres @ 64.2% Fe from surface and 15 metres @ 60.7% Fe from a depth of 56 metres in borehole RC12RR082,
  • 57 metres @ 56% Fe in borehole RC12RR075 from a depth of 3 metres, (intersection includes an interval of 33 metres @ 61.8% Fe from 25 metres),
  • 27 metres @ 58.6% Fe from a depth of 7 metres in borehole RC12RR076,
  • 39 metres @ 58.7% Fe in borehole RC12RR077 from a depth of 27 metres, (intersection includes an interval of 30 metres @ 60.8% Fe from 29 metres),
  • 23 metres @ 55% Fe in borehole RC12RR078 from a depth of 45 metres, (intersection includes an interval of 12 metres @ 61.3% Fe from 46 metres),
  • 2 metres @ 55.1% Fe from a depth of 4 metres, 14 metres @ 55.4% Fe from a depth of 10 metres and 38 metres @ 55% Fe from a depth of 28 metres in borehole RC12RR068 (intersection includes an interval of 20 metres @ 60.2% Fe from a depth of 36 metres).

Independent technical specialists, H & S Consultants Pty Ltd, were commissioned to undertake a resource estimation for PNN Area C. A maiden Mineral Resource Estimate reported to JORC standards of 4.65million tonnes grading 55.2% Fe in the Inferred Category was announced on 28th December, 2011. A revised JORC Resource Estimate was announced on 6th June, 2012 as follows;

Field reconnaissance and surface sampling were also undertaken over two new prospect areas designated as “PNN Area-E” and “PNN Area-F”. More than fifty percent of the 21 surface samples collected from within PNN Area “E” returned assays in excess of 55% Fe and ranged up to a maximum of 66.4% Fe. Nine samples were collected from within PNN Area “F” and returned assays ranging from 32.2% Fe to 66.2% Fe.
