Polymetal International Plc

Announcement of reserves and resources update as at 1 January 2012

 

Polymetal International Plc (LSE: POLY) (together with its subsidiaries, including JSC "Polymetal" - "Polymetal", the "Company", or the "Group") is pleased to provide an update on its reserves and resources as at 1 January 2012.

 

Highlights

 

·      10% decline in gold equivalent content of Ore Reserves driven mostly by reserve depletion; Mineral Resources up 2% mainly as a result of new resources added at Dalneye.

·      Conservative precious metals prices used for reserve estimation (US$ 1200/oz for gold and US$20/oz for silver) leave substantial amounts of economically mineable material outside reserve estimates, particularly at Dukat mine.

·      Average reserve grade remains at a high 4.2 g/t of gold equivalent, and average resource grade - at 3.9 g/t of gold equivalent.

·      Gold equivalent data is presented in this report based on 1:60 Ag/Au and 5:1 Cu/Au conversion ratios

"We expect that a modest reduction in Polymetal's ore reserves in 2011 will be more than reversed in 2012 as our exploration efforts translate into new significant reserve and resource additions,"said Vitaly Nesis, CEO of Polymetal.
