  1. 1. Company UpdateGold Symposium: 14 November 2011
  2. 2. Investment Highlights• Financially attractive shallow underground „Starter Mine‟ – Free cash flow ~A$125M; NPV (8%) ~$81M ($A1,550/oz) – Free cash flow ~A$185M; NPV (8%) ~$127M ($A1,800/oz) – Recovered metal: ~250,000oz gold, 73,000oz silver – High grade gold (7.24g/t undiluted) – $697/oz C1 cash cost (includes 10% contingency)• Excellent partnerships in place to progress development of Dargues Reef – Mining, plant construction, concentrate treatment, bank debt etc• Near-mine exploration success suggests potential to significantly improve mine-life and project economics – 12.6m @ 9.90g/t & 5m @ 10.6g/t (Ruby Lode), 1m @ 103g/t (Chinamans) – not in model – RC drilling to commence this month targeting near-mine discoveries• Considerable regional upside potential with drill-ready targets – 700km2 of tenure in the highly endowed Lachlan Fold Belt2
  3. 3. Corporate Snapshot September 2011 CRC Shares on Issue ~221M Listed Options (CRCO) on Issue (20c) 34M Unlisted Options on Issue (~50c) 16M Share Price $0.11 Market Cap ~$24M Cash & Deposits (September 2011) ~A$3.0M Debt * Nil * $1 million cash and $4 million shares payable to Moly Mines on development funding Shareholding Baker Steel 13.3% Moly Mines 6.1% Board and Management 4.6% GBF (Mining Contractor) 3.2% Other Top 40 Shareholders 24.4% Other Shareholders 48.4%3
  4. 4. Majors Creek Gold Field Reviving the Golden Heritage • 700km2, southern Lachlan Fold Belt • Sydney ~3hrs, Canberra ~1hr • Potential to open new gold district • New mine development at Dargues Reef4
  5. 5. Dargues Reef Project Location Freehold Land Owned 100% by Cortona5
  6. 6. Dargues Reef “Made to Mine” • Gold production from 35 metres depth with resource defined to 480 metres – remains open • Initial 6-year mine life at av. 330,000tpa production rate • Remarkable continuity of grade and mineralisation • Conventional underground mining method – top-down long-hole open stoping • Paste-fill to allow full ore body extraction • Small, efficient mining fleet6
  7. 7. Dargues Reef Status of Key Milestones • Key contracts are awarded, others are well advanced • Mining Awarded (GBF) • Process Plant Awarded (DRA Pacific) • Milling Mill order imminent • Power Awarded • Box Cut Ready to award • Access Road Ready to award • Infrastructure Ready to award • Tailings Storage Final design underway • Major underground equipment procured (GBF) • Mandate with Deutsche Bank for $37M bank financing – credit approval expected late October 2011 at which point financing conditional only upon equity • Concentrate agreement in place; Parkes Shire Council modification approvals in progress – expected early 2012 • State and Federal environmental approvals in place • Decision appealed to the NSW Land and Environment Court • Paste plant – Consent modification expected early 20127

  10. 10. An Analogue - Challenger Gold Mine Breaking the Rules of Thumb! “Experience has demonstrated that the high grade structures • Underground commenced on 257,000oz R & R at Challenger have excellent continuity. However, they are • Initially ~700 OVM (when GP was A$550/oz!) difficult to define without close • Up to 150m vertical development per year spaced information which is most effectively gained from • Mined ~100,000oz per year for 6 years underground access.” Kingsgate Website, June „11 • Current R & R >1.0Moz10
  11. 11. Recent Near Mine Discovery Success • Significant new gold discovery ~150m north of Dargues Reef: Ruby Lode • 12.6m @ 9.90g/t & 5m @ 10.6g/t • Open along strike and at depth • Not in model - potential to add resource ounces, near term production and mine life • Numerous other near mine targets to be11 tested
  12. 12. Copper Ridge, 1km from Dargues • <1km from Dargues • Mineralisation identified for >1km strike • Rock chips to 6.0g/t gold and 185g/t silver • Soils +200ppb • Epithermal signatures • Potential to add resource ounces, near term production and mine life • RC drilling program to commence mid-September12
  13. 13. Excalibur, 2km from Dargues • ~2km from Dargues • Widespread mineralisation identified at surface • Rock chips to 8.0g/t • Soils +200ppb • Drill results include: • 19m @ 5.6g/t gold • Dargues „pyrite‟ style • Potential to add resource ounces, near term production and mine life • Drilling program being planned13
  14. 14. Regional Exploration• Tenements cover 700km² of highly prospective Lachlan Fold belt tenure• New geological model has regional application• Several Dargues Reef „look-a-like‟ structures identified• Additional targets based on alteration associated with large porphyritic intrusion• Aim is to increase production and further extend mine life14
  15. 15. Summary• Dargues Reef - Australia‟s next new gold mine• Initial +50,000oz pa production forecast to commence 2012• High-grade deposit, favourable characteristics – “Made to mine”• Moderate cash costs, strong cash flows• Robust „base-case‟ on which to grow• Modular 330,000tpa treatment facility with growth optionality• Exploration delivering success, with RC drilling to commence mid-September – Ruby Lode (depth extension) – Copper Ridge (potential for new discovery) – Excalibur (potential for new discovery)15
