CATHERWOOD RESOURCE UPGRADE and OPTIMISATION KUNANALLING PROJECT

Following the successful results from recent drilling at the Company's Kunanalling project a reestimation and interim optimisation for mining of the Catherwood resource has been completed.

Resource

The work has resulted in an increase in the previously announced resource at Catherwood and indicates that the orebody can potentially be profitably mined. The resource now stands at:

574,000T @ 2.4 g/t Au cut (44,700 ozs. Au)

The result represents an increase of 43% in contained gold from the previously announced resource for Catherwood of 332,000 t @ 2.9 g/t Au. The resource represents part of the total resources estimated for the Kunanalling project of: 5.1 Mt @ 1.9 g/t Au (308,000 oz Au).

-- -- -- ------------------------------------------------

The resource was modelled using 1 g/t Au grade envelopes with 2m internal dilution and 1m external dilution. The resource is reported from model blocks using a 1 g/t cut-off grade. Grade estimation used top cuts of 25 g/t Au (Main Lode) and 20g/t Au (HW) and SG values were assigned by RL over 4 domains and are based on data measured from core.

Additional low grade material, comprising material 0.5 to 0.99 g/t Au from the oxide and transition zones only, exists within the mineralised envelopes at Catherwood. These comprise Indicated Resources of 115,000 t @ 0.80 g/t Au and Inferred resources of 36,000 t @ 0.77 g/t Au for a total low grade resource of 151,000 t $@$ 0.80 $q/t$ Au. Cazaly considers that these resources could be stockpiled during mining operations and could potentially comprise ore feed to a large heap leaching operation in the Kunanalling Project area.

Resource Optimisation

An optimisation study of the updated resource for Catherwood was carried out by Golder Associates. Two separate milling scenarios were run, incorporating variable toll milling, trucking, mining and administration costs and using AUD gold prices of \$550, \$575 and \$600. Using the \$575 gold price and a total operational cost of \$29/t, then the Catherwood resource would produce: 97,000T @ 4.0 g/t Au (11,330 oz Au) for a revenue of A\$1.8M

A summary all material within the optimal pit shells is presented below in Table 2.

Table 2: Summary of Catherwood Resource within optimisation shells

The resources reflect what could be expected to be mined once pit design and scheduling were completed. The results are only to be considered as scoping study level as further drilling is required to upgrade the status of the resource and mine planning has yet to be conducted.

It should be noted that the resource lies within a granted Mining Lease and is adiacent to major haul roads which access several mills in the region. Preliminary planning for statutory approvals to mine has also begun. Development work will be ongoing in conjunction with the assessment of the other resources within the Kunanalling project.
