• Ore body is a breccia pipe hosted in limestone.

• The pipe is elliptical in shape and the N and S contacts dip outward at 60 and 80 degrees respectively.

• The western contact dips at 45 degrees and the eastern limit is unknown. Mineralisation appears to be confined to the western contact.

• Primary mineralisation is chalcopyrite

• minor amounts of bornite and other exotic copper sulphides.

Recommissioning & Mining Strategy

==> picture [174 x 97] intentionally omitted <==

Recommissioning can be accelerated due to the existing high quality site infrastructure and good condition of underground workings

It is projected that mining operations will recommence within 6 months of project financing/final permitting with full production two months later

The project will use the same mining method as the original operation and experienced staff have been sourced e.g. Chief Mining Engineer who has previously worked at the project

Two options exist for processing:

1. Toll treatment of the ore via local processing facility

2. The preferred option and negotiations are underway for a toll treatment agreement

3. Purchase of a mill to produce a concentrate

4. The company has an option to purchase a used 500,000tpa mill

Competent Person’s Statement

==> picture [174 x 97] intentionally omitted <==

Competent Person. The review of exploration activities and results contained in this presentation in relation to the Company’s projects is based on information compiled by Mr. Richard Holmes. Mr. Holmes is a Member of the Australasian Institute of Mining and Metallurgy and has sufficient experience which is relevant to the style of mineralization and types of deposits under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the December 2012 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code). Mr. Holmes consents to the inclusion of this information in the form and context in which it appears in this presentation.

Information in this report that relates to Mineral Resource estimates reflects information compiled by Mr Alexey Zharnikov a full time employee of CSA Global Pty Ltd, who is a member of the Australian Institute of Geoscientists (AIG). Mr Zharnikov has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is reporting to qualify as a Competent Person as defined in the 2004 Edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves.” Mr Zharnikov consents to the inclusion in the report of the matters based on the information compiled by him, in the form and context in which it appears.

*Copper Equivalent Calculation

Copper Equivalent (CuEq) represents the total metal value for each metal, multiplied by the conversion factor, summed and expressed as equivalent copper percentage. These results are exploration results and no allowance is made for recovery losses should mining eventually occur. However it is the company’s opinion that the elements considered here have reasonable potential to be recovered as evidenced by production records from previous mining activity at the project and comparable in the region.

Drill Intersections

Copper Equivalent Formula = Cu% + Au(ppm) x 0.7292 + Ag(ppm) x 0.0146 + Zn% x 0.3

Price Assumptions Cu (US$3/lb), Au (US$1500/oz), Ag (US$30/oz), Zn (US$0.90/lb)

Resource Estimate

Copper Equivalent Formula = Cu% + Au(ppm) x 0.6076 + Ag(ppm) x 0.0097 + Zn% x 0.3 Price Assumptions Cu (US$3/lb), Au (US$1250/oz), Ag (US$20/oz), Zn (US$0.90/lb)
