Centamin Plc - Updated Resource and Reserve Statement
18.12.2013 | Marketwired
PERTH, AUSTRALIA -- (Marketwired - Dec 18, 2013) - Centamin plc ("Centamin" or "the Company")(LSE: CEY) (TSX: CEE) is pleased to provide an update to its resources and reserves for the Sukari Gold Mine as outlined below.Highlights
- Total Measured and Indicated resource containing 13.4 million ounces (Moz) (previously 13.1Moz) comprising open pit resource of 12.6Moz and underground resource of 0.8Moz.
- Total combined open pit and underground reserve containing 8.2Moz, down 19% from 10.1Moz at 31 December 2011 due to mining depletion and increased mining and processing costs associated with a change from subsidised to international fuel prices.
- Open pit and surface stockpile reserve containing 7.7Moz.
- Underground reserve of 2.30 million tonnes (Mt), a 120% increase on 1.1Mt at 31 December 2011.
- Underground proven component of the mineral reserve of 0.52Mt grading 11.4g/t gold provides support that further higher grades will continue to be defined as drilling and development continues.
- Resource and reserve definition continues in parallel with expanding underground infrastructure, targeting high grade areas.

Underground Reserve
The component of the combined reserve as outlined above that relates to
the underground operation is summarised below.
Tonnes Grade Contained gold
Reserve ('000 t) (g/t Au) ('000 oz)
Proven 520 11.4 191
Probable 1,815 6.0 349
Total 2,335 7.2 540
Notes to Table:
- Totals may not equal the sum of the components due to rounding adjustments.
- Stopes for reserves are then designed using a 3g/t cut off and mining dilution applied at 15% @ 0.8g/t as all stopes are located in mineralised porphyry and 10% mining loss is then assumed to allow for stope bridges and material left in stopes after mining.
An updated NI 43-101 resource and reserve report will be completed and filed in due course on SEDAR at www.sedar.com and on the Company's website.
Josef El-Raghy, Chairman of Centamin, commented:"As expected there has been some impact on the overall reserve from the higher international fuel price environment that Sukari has operated under since Q1 2012. However, it is pleasing to note that the underground drilling campaign, which has escalated steadily during 2013, has started to outline substantial regions of high grade ore. It is our expectation that this trend will continue as underground development is expanded and the multiple high-grade drill targets at Sukari are tested and defined over the coming months and years."

ABOUT CENTAMIN PLC
Centamin is a mining company that has been actively exploring in Egypt since 1995. The Company's principal asset is its interest in the large scale, low cost Sukari Gold Mine, located in the Eastern Desert of Egypt. The operating company Sukari Gold Mines is jointly owned by Centamin's wholly owned subsidiary Pharaoh Gold Mines NL and the Egyptian Mineral Resource Authority on a 50% equal basis. Sukari produced 150,000 ounces of gold in its maiden year of production in 2010, consistently expanding thereafter to reach over 260,000 ounces in 2012. The 'Stage 4' plant expansion programme commenced in 2011 to target 450-500,000 ounces per annum production from 2015 onward. The Sukari Gold Mine is the first large-scale modern gold mine in Egypt.
Centamin's operating experience in Egypt gives it a significant first-mover advantage in acquiring and developing other gold projects in the prospective Arabian-Nubian Shield. In 2011 the Group acquired, through Sheba Exploration Holdings Limited, four mineral licences in Ethiopia where it is conducting further exploration activities. In September 2013, the Group entered into a joint venture with Alecto Minerals plc ("Alecto") to pursue existing and new opportunities identified by Alecto in Ethiopia. The initial joint venture projects relate to two exploration licenses, Wayu Boda and Aysid Meketel.
