Kihabe Project - Defined Resources

The above Kihabe resource statement was calculated by Ravensgate Pty Ltd, geological consultants on the 17th July 2008, on which date zinc and lead were trading at US$1810/t and US$1995/t respectively. The above Nxuu resource statement assumes a par value for both Zinc and Lead.

* Combined Resources of 29.9 million tonnes @ 2.62% zinc equivalent grade applying a 0.5% external cut

Kihabe Zinc/Lead/Silver Resource - Facts

  • Sedex

Style open cut resource

  • Mineralisation occurs within a quartz wacke on an almost

vertical contact with a dolomite

  • Resource calculated from 19,300m drilling

(12,900m RC and 6,400m diamond core drilling)

  • Resource of 22 million tonnes, calculated to 175m depth

from surface, over a strike length of 2.4 km

  • Resource calculated by Ravensgate, Independent

Nxuu Zinc/Lead Resource - Facts

  • Sedex

Style open cut resource

  • Mineralisation occurs within a flat lying quartz wacke on

the contact with a dolomite

  • Resource calculated from 1400m drilling

(500m RC and 900m of diamond core drilling)

  • Resource of 10.9 million tonnes

calculated to maximum 80m depth by Ben Mosigi, Technical Director (MSc., BSc., Member Geological Society South Africa)

Kihabe/Nxuu Resource Facts

Float Concentrate 60% metal

  • Higher concentrates expected from

45% increase in metal recoveries

ProMet Engineers Scoping Study May 2009 Room for Improvement Updated/Subject to Change since Scoping Study

Concentrate costs (Transport) US $123/t

  • 1. Higher concentrates expected

from 45% increase in metal recoveries

  • 2. Less concentrates to be transported

as a result of onsite electrowinning of zinc metal from oxide ores Smelting US $182/t concentrate Variable according to smelter

  • demand. Chinese smelters currently

around US$190/t concentrate Capex US $217 million

  • Change in process flow sheet : on-site

electro-winning of metal from oxide

  • res will increase Capex

IRR Based ONLY on metal recoveries of 64% Zinc and 67% lead, project was estimated to yield IRR of 26% @ 30% equity, with metal prices @US$2,400/t

  • 45% increase in metal recoveries, 20%

increase in grade, 10% increase in resource & on-site electrowinning should increase IRR significantly, subject to additional Capex. Updated Scoping Study will reflect this
