Orsu Metals Corporation ("Orsu", or the "Company") (TSX:OSU, AIM:OSU), the London-based precious and base metals exploration and development company, is pleased to announce the positive results of a scoping study for the Tadybulak Gold-Copper-Molybdenum Porphyry Deposit ("Taldybulak") at its Talas joint venture project in the Kyrgyz Republic (the "Taldybulak Scoping Study"). Gold Fields Limited ("Gold Fields"), through its subsidiary Gold Fields Orogen Holding BVI Limited, has a 60% interest in the Talas joint venture company (the indirect owner of the Taldybulak, Barkol, Kentash and Korgontash licenses in the Talas region of the Kyrgyz Republic (the "Talas Project")), whilst Orsu retains a 40% interest in the Talas Project. Gold Fields is the project manager.
The Taldybulak Scoping Study establishes key design criteria for an open pit mine scenario with a 15 million tonnes per annum ("Mtpa") processing facility for average annual recovery of 242,000 oz gold and 137,600 dry metric tonnes ("dmt") of copper concentrate and 1,880 dmt of molybdenum concentrate via conventional communition and floatation process flow sheets at estimated initial capital expenditures of approximately US$516 million.
Taldybulak has been the primary focus of exploration and mineral resource development within the Talas Project licence area. The Talas Project is located 250 km west of the Kyrgyz capital of Bishkek and is accessible all year via paved road up to the last 20 km. The national electrical grid is close to the deposit and there is a 110kV sub-station 20km from the site. There is a potential water source for future operations from ground water aquifers and from the Karakol river. The average project elevation is approximately 2,000 m and the nearest village with a population of 3,500 people is 7 km away. The larger town of Talas with 30,000 people is approximately 50 km to the west. The nearest railhead is at Maimak on the Kazakhstan border, approximately 160 km away via paved road.
Coffey Mining Pty Ltd (Perth, Australia) ("Coffey Mining") completed the Taldybulak Scoping Study on behalf of the Talas joint venture, which formed a basis for a pit-constrained mineral resource update for the deposit. This was done according to the 2007 South African Code for the Reporting of Mineral Resources and Mineral Reserves (the "SAMREC Code Resource"). The SAMREC Code Resource contains 127 Mt in the indicated category, which is comprised of 2.6 Moz gold at 0.64 g/t, 477 Mlb copper at 0.17%, and 29.4 Mlb molybdenum at 0.01%, and 296 Mt in the inferred category, which is comprised of 3.71 Moz gold at 0.40 g/t, 1,098 Mlb copper at 0.17%, and 69.2 Mlb molybdenum at 0.01%. The mineral resource was calculated using metal prices of US$1,150/oz Au, US$3.00/lb Cu, US$15/lb Mo ("Resource Price Case"), which was reported in the Company's press release dated September 27, 2010.
Preliminary metallurgical test work (as reported by Orsu in its press-release dated July 21, 2010) indicated that the recovery of gold, copper and molybdenum should be possible using a conventional communition and flotation process. Based on metallurgical test work results, a conceptual process flow sheet has been developed consisting of crushing, grinding and bulk flotation to produce a gold-copper-molybdenum concentrate. The concentrate would then undergo a further flotation stage to produce both a copper-gold concentrate and a molybdenum concentrate. In this scenario some copper must be present in order to recover any other elements, therefore any Standard Mining Unit ("SMU") containing some gold but zero copper would not be profitable to treat. Due to the polymetallic nature of the Taldybulak ores, material that is profitable to treat is not simply based on a single element cut-off grade. Figure 1 shows which material is potentially economic at various copper and gold grades for a maximum cashflow scenario using the Resource Price Case, i.e., US$1,150/oz gold, US$3.00/lb copper, and US$15/lb molybdenum metal prices. Due to the minor contribution from molybdenum, an average molybdenum grade of 0.011% molybdenum is assumed. The copper grade that is economic to treat excluding gold credits is approximately 0.16% Cu.
