Highlights:

• RC drilling program now underway at the Big Rush Gold Project, the largest historic gold producer of the Company's three gold mines;
• Big Rush drilling program designed to validate historic drilling information;
• Golden Cup drill program complete with results expected over the coming weeks.

Big Rush

RC drilling is now underway at the Big Rush Gold Project, located on 3 granted Mining Leases, 200km West of Townsville (Photo 1 & Figure 2). The program of approximately 1,000m is designed to confirm historic drilling and allow the estimation of a JORC-compliant gold resource at Big Rush. The planned drilling program is confined to the Central Pit area at Big Rush. The Central Pit area represents a small part of the Big Rush mineralised system which extends for a kilometre both north and south of the Central Pit (Figure 1). The drilling of these extensions represents a strong exploration target which the Company will look to test in the next program.

Golden Cup

An RC drilling program at the Golden Cup Gold Project has now been completed with a total of 8 holes drilled for 639 metres (Table 1). Drilling was undertaken by contractor Eagle Drilling NQ Pty Ltd of Charters Towers. The entire length of each drill hole has been sampled, either as 1m or composited samples, and these 302 samples are at Intertek Ltd's assay laboratory in Townsville with assay results expected over the coming weeks.
