JORC Resource Estimate following 2012 Asacha exploration programme

• 11,000 metres drilled on Asacha’s flanks in 2012

• Asacha JORC resource update adds 321,000 oz. gold and 703,000 oz silver, net of 2011 and 2012 production (252,000 oz. of gold and 395,000 oz. of silver in Asacha’s Eastern zone identified in 2012)

Asacha mine

• Daily output of 500-600 tonnes of ore ensures continuous operation of the plant

• Processing plant throughput is close to the designed 12,500 tonnes of ore per month

• Major issue of concern – low grades and high dilution

Page 8: TRANS-SIBERIAN GOLD PLC

2012 major issue of concern:low grades and high dilution

– fractured and fragile enclosing rocks in blocks close to surface

– design disadvantages:• long hole blasting inappropriate for some

parts of the mine• blasting scheme unsuitable for some blocks

– shortcomings in earlier mine development:• advanced block preparation• inadequate and timely supporting

– lack of underground machines– lack of experienced personnel

Page 9: TRANS-SIBERIAN GOLD PLC

Measures taken following 2012 technical audit

• New technical and managing staff – Technical director and Chief mine geologist, each with around 30 year practical experience

• Measures to keep mining blocks’ integrity– minimise time lag between preparation of mining blocks and subsequent stoping– use rock drifts when preparing blocks for stoping

• Measures to reduce dilution- short blocks stoping, recoverable protective pillars and supporting concrete pillars/ceilings, where appropriate - changes in blasting scheme, including drilling blasting holes parallel to the ore body, shallow blast-hole blasting where appropriate, less brisant explosives and drilling blasting holes with smaller diameters- smaller machines (scrapers and LHD)- stricter control on ore blasting and haulage to reduce volume of ore stored underground

• Optimisation of work shifts

• More attention to ore sampling, stockpiling and blending

• VNIPI design institute to revisit Asacha in near future

The aim – to achieve 8 g/t gold grade by the end of 2013 and 9 g/t by mid 2014

New underground machines

• BU-80 rig with smaller diameter (65-75 mm instead of 105 mm)

• Two underground LHD : Fambition FAML-3 and Atlas Copco ST2D

• Underground truck Fambition FAMT-12T

• Federal authorities prescribed the implementation by April 2014 of two provisions of the Licensing Agreement:– Finalisation of the design

documentation– Commencement of work at

the deposit• The pre-feasibility study will

be finalised in 2013
