Quarterly Exploration Report: September 2012 EKJV Quarterly Activity
Summary
This report provides a quarterly report on work conducted by Barrick Kanowna on the East Kundana Joint Venture (EKJV). The EKJV is a joint venture between Barrick Gold subsidiary company Gilt-Edge Mining NL(GEM) and Rand Mining Ltd and Tribune Resources Ltd.
Work was conducted on two prospects within the EKJV on mining lease M16/309. They were:
Pegasus, and
Drake.
At the Pegasus prospect two resource development drill programs were undertaken. These included completing geotechnical and metallurgical drilling and condemnation drilling, as well as resource infill drilling.
At the Drake prospect area a resource development drill program was completed.
Figure 1 shows a collar plan of the September quarter drilling.
Pegasus
The September quarter of 2012 saw a substantial amount of drilling take place at the Pegasus deposit to infill existing drill data in the near surface mineralisation adding to the work completed in the first half of 2012, as well as some mine feasibility work for mine optimisation.
Two drill programmes consisting of 38 drill holes were drilled within the Pegasus project following on from positive outcomes achieved in 2012. Objectives for the drill programmes included the completion of the infill drilling of the high grade core of the Pegasus Open Pit deposit, depth testing of the K2 structure, infilling between the deeper drilling and the optimised pit and the completion of the condemnation programme of an area for the proposed waste dump. Also completed were the drill holes for geotechnical information and metallurgical testing.
Figure 2 shows an updated long projection of the K2 mineralisation for the Pegasus project.
Drilling
A total of 19 diamond drill holes were completed during the quarter for a total advance of 4,697.9m. A total of 19 reverse circulation drill holes were drilled for a total advance of 3,033m.
Results for this are tabled below (Table 1). Significant intersections are listed:
| PGCD12017 | 4.0m @ 46.0 g/t Au from 195.0m and |
|---|---|
| 8.9m @ 10.4 g/t Au from 213.0m | |

| PGDD12059 | 19.1m @ 8.13 g/t Au from 131.8m |
| PGDD12060 | 13.6m @ 16.4 g/t Au from 137.8m |
| PGRC12064 | 38.0m @ 7.23 g/t Au from 94.0m |
| PGDD12096 | 4.0m @ 12.7 g/t Au from 164.0m |
| PGDD12110 | 7.0m @ 5.84 g/t Au from 213.0m |
| PGDD12116 | 4.2m @ 9.44 g/t Au from 55.0m |
Drake
A small infill drill program was c ompleted at the Dr a ke prosp e ct. The Drake pro s pect is a p proximatel y 200m nor t h along strike from th e Pegasus d eposit on t he same s t ructure.
Drilling
A t otal of 10r e verse circ u lation drill h oles were drilled for a total adva n ce of 1,42 4 m. R e sults for this are tabled below (T a ble 1). Si g nificant int e rsections a re listed: DRRC12001 4.0 m @ 3.7 g/ t Au from 1 3 3.0m DRRC12010 2.0 m @ 11.5 g /t Au from 145.0m

K2 is the main mineralised surface and spans a carbonaceous shale unit, the Centenary Shale. Where the shale unit is thick and the position of the vein is distinct, K2 has been sub‐divided into the K2 vein on the footwall of the Centenary Shale (K2_CFW), and K2 vein on the hangingwall of the same shale (K2_CHW). K2B and K2A are sub‐parallel structures analogous to K2, but positioned in the hanging wall basalt. K2, K2A and K2B are all part of the same suite of shears that form part of the regional Zuleika Shear Zone.
