  • Future Exploration: Focus on expanding Paris resource Proposed A$3m allocation for balance of FY: 1. Focus on the Paris expansion target area • In progress late 2013: First-pass aircore drilling (c. 7,500m) of all immediate target extensions • Early 2014: Diamond drilling (c. 60 holes) of best resource expansion opportunities within and extending from Paris 2. Continue to assess Peterlumbo camp potential • Scout aircore drilling of Helen/Diomedes silver & copper soil targets 3. Further work on:• Uno/Morgans epithermal silver targets; & • Roundabout/Spyall IOCG targets awaiting final access approvals before progressing later in 2014 28 www.investres.com.au
