EKJV Exploration Quarterly Report

March 2014

1 SUMMARY

East Kundana Joint Venture

A total of 7795.16m of diamond drilling and 3767.3m of RC drilling were completed during the quarter. The drilling was undertaken at the Kundana camp at two prospects, Pegasus and Ambition. At Ambition 7 RC drill holes were completed for a total of 1110m. At Pegasus 2657.3m of RC was completed drilling 12 diamond pre‐collars and 3 RC drill holes, and 15 diamond drill holes and 4 diamond drill tails were completed for a total of 7795.16m.

2 DRILLING

7795.16m of diamond and 3767.3m of RC was drilled during the Quarter. Drilling was at two prospects in the EKJV, Ambition and Pegasus. Ambition is a drill testing stage project and is in the initial stage of drill testing a distinct soil geochemical anomaly along strike to the north of the K2 structure and stratigraphy.

2.1 Ambition

A soils and lag sampling programme north of the Arctic Mine (K2 structure) in the Kundana area defined a tungsten‐arsenic anomaly consistent with the other deposits along the Zulieka shear. A stratigraphic diamond hole drilled in late 2013 tested this anomaly and identified elevated gold grades in a laminated shear vein on a major structural contact (0.25m @ 0.27g/t).

A RC drill programme commenced in late February to define the position of K2 and test the tenor of veining on that contact. A total of 168m were drilled under Barrick Gold ownership in February, with one hole completed. The remaining holes were drilled in March for 942m giving a total programme of seven RC holes for 1,110m.

All holes drilled to date have positively identified the position of the mineralised structure. A key aim of the project was to determine the location and structural position of the gold anomalism and improve the geological interpretation in the northern Kundana Zuleika area. Previous structural interpretations have been limited to aeromagnetic imagery. Three holes have identified elevated gold grades on the structure of a magnitude consistent with the grade of the structure proximal (~200m) to the Kundana‐style orebodies to the south. All assay jobs returned for Ambition have passed QAQC checks.

2.2 Pegasus

During the quarter, three surface diamond rigs drilled a total of 7795.16m for advanced exploration and resource definition drilling programmes throughout the Pegasus prospect, focusing on three main areas of mineralisation, Polaris, Centauri, and the Jewellery Box (Figures 2 and 3). An RC rig was also present during the quarter drilling pre‐collars and RC holes for a total for a total of 2657.3m. In total, 10,452.46m were drilled at Pegasus during the March Quarter.

Two advanced exploration holes (PGCD14003, PGCD14005) were drilled at depth below the Pegasus resource, at approximately the 5750 level, to help bring the area up to a sub inferred category (based on 160m x 80m drill spacing). These two holes had RC pre collars drilled in February; with PGCD14005 intersecting a thin but well mineralised K2 intersection with multiple visible gold crystals.

Four advanced exploration holes (PGDD14002, 14009, 14021, and 14029) were drilled at varying depths throughout the Polaris area, an area to the north of the Jewellery Box with four holes drilled in 2012 that returned significant K2 intersections. These four holes were drilled as part of the longer term aim to upgrade the area as an inferred resource category (80m x 80m drill spacing), as well as filling in the area between the Jewellery Box and Polaris areas to a sub‐indicated resource category (40m x 80m drill spacing). Three holes, PGDD14009, 14021, and 14029, all intersected highly favourable K2 veining, with visible gold in 14009 and 14029. PGDD14009 is highly mineralised and wide (~4m), and returned very favourable results (9.0m @ 37.8 g/t Au).

In total thirteen RC pre‐collars (PGCD14003, PGCD14005 – 14007, PGCD14020‐14027), ranging from 60 ‐ 270m depth, were drilled at approximately the 5850 level across the width of the Polaris and Centauri areas (combined strike of approximately 600m). To date five of the diamond tails have been drilled (PGCD14003, PGCD14005‐14007 and PGCD14021), with another seven yet to be drilled.

Two shallow advanced exploration holes were drilled on the northern edge of the Pegasus resource in an area with previous sparse drilling, the majority of which was RC drilling only. These two holes were drilled to target the possibility of northerly plunging shoots extending downwards from the northern proposed pit edge towards high grade intercepts in the Polaris area. PGDD14018 (~6100 level) was thin but well mineralised with visible gold and but provided much needed structural and textural data in an area that previously contained only RC intercepts.

Three resource definition holes (PGDD14012, 14019, 14028) were drilled as a down dip extension to the Jewellery Box mineralisation, with the aim of adding width to the highly mineralised vertical plane defined by PGDD13033 and 13034 drilled late 2013. Both PGDD14012 and 14028 were thick (3m and 6m respectively) and highly mineralised, with common visible gold. PGDD14028 should return favourable results based on its mineralogy, visible gold content and width (PGDD14019 was aborted due to significant swing to the south and was redrilled as PGDD14028).

3 ASSAY QAQC

Overall laboratory performance for these jobs was good with none of the submitted company standards and one laboratory standards falling outside of +/- 3 standard deviations out of and only three warnings for outside 2 standard deviations (Table 2). Two blanks failed, both relating to a swap of material for a screen fire assay (decision on appropriate response pending). One lab standard failed in January, and four other lab standards reported warnings outside 2 standard deviations over 3 month reporting period. No lab blanks were above 0.05 g/t gold.

All grind checks passed at both the 3mm (113 samples) and 75µm (198 samples) levels.

Repeatability for the reporting period was slightly poorer than for the previous reporting period. There is a slight bias towards higher grades in the original compared to repeat (LR1, LR2, LR3) assays, however, this is an artefact related to the lab procedure for selection of repeat samples which selectively targets the top percentile of assays in the original data. (high values that come back low are repeated, but low values that would have come back higher are not selected). There were insufficient field duplicate samples to undertake any meaningful analysis.

The first reference to the mineralization style encountered at the
Pegasus project was the mines department report on the area
produced by Dr. I. Martin (1987). He reviewed work completed in
1983 – 1984 by a company called Southern Resources, who
identified two geochemical anomalies, creatively named Kundana #1

contact between the victorious basalt and Bent Tree Basalt (both part
of the regional upper Basalt Sequence).
A 60° W dipping fault, offsets this contact and exists as a zone of
