   --    Substantial gold production and mine life maintained over a range of gold prices 
   --    Sound cash margins indicted under all scenarios evaluated 
   --    Indicative cash costs some 20% below PFS estimates

Bullabulling Gold Limited reports that initial pit optimisation runs have been completed for the Bullabulling Gold Project indicating substantial gold production and mine life under a range of gold price scenarios. Results are summarized in Table 1 below.

The pit optimisations, which were performed using Gemcom Whittle(TM) software, are part of a broader mining optimisation process that is being carried out during the initial phase of the Bullabulling Gold Project definitive feasibility study (DFS).

Production levels and mine life for the $1,350 per ounce scenario most closely match the Bullabulling prefeasibility study (PFS) results, however indicated cash costs at $850 to $950 per ounce are in the order of 20 percent below PFS estimates.

It is expected that in common with the PFS, cash costs in the early years of the project will be substantially lower than the life of mine average. The expansion of high grade resources in the Edwards/Gryphon area following a recent drilling campaign is expected to assist in sustaining lower cash costs early in the mine life.

Detailed pit designs will now be prepared using the Whittle pit shells as a base. Production scheduling and financial modelling will follow, with release of a re-optimised economic assessment targeted for mid-year.

The pit optimisations have been based on the recently updated resource model (see release of 13 May 2013). As foreshadowed following completion of the Edwards/Gryphon drilling program, the optimiser has confirmed that the two deposits can be mined by a single pit. In common with the PFS, three pits were defined on the northern part of the Bullabulling trend, separated by the highway and power line corridors.

Owner mining was assumed, which contributed to lower unit mining costs relative to the PFS. Haulage costs were further reduced through placing waste on both sides of the main Phoenix pit, which became viable following the acquisition of a mining lease situated immediately west of the deposit from Resolute Mining in December 2012. Refinements to pit slope design and relocation of the main haulage ramp to the western side of the deposit reduced waste mining requirements and improved strip ratio.

It has been assumed that Bullabulling would be connected to the south-west electricity network via the high voltage transmission line that traverses the project tenements and that power would be procured from a combination of south-west and local sources.

Key processing inputs were unchanged from the PFS numbers.

Notes

1. The Whittle optimisation process provides an indication of mining inventory and cash costs. Conversion of an optimiser pit shell to a detailed design can be expected to result in some changes in tonnage mined, strip ratio and costs.

2. The cash costs in the results table are C1 costs and encompass mining (including all waste mining), processing and site administrative costs, but exclude pre-production capital, sustaining capital, corporate costs and royalties.

3. The mineralisation within the pit shells consists of both Indicated and Inferred resources and as such cannot be reported as a Mining Reserve. A breakdown by resource classification is presented in Table 2 below.
