Asacha mining and production update

LONDON: 23 January 2013 - Trans-Siberian Gold plc ("TSG" or the "Company") (TSG.L) reports that mine development activities at Asacha in the fourth quarter of 2012 comprised approximately 964 metres, while ore extraction (including ore from stoping and mine development) amounted to 37,387 mt, the highest quarterly total to date.

In the same period, an average 12,357 mt per month was processed by the Asacha plant.

Mining and production at Asacha in 2012 is shown in the following table.

As reported on 29 October 2012 the need to blend mined ore with lower grade ore from the surface ore stockpile (because the breakdown of some underground equipment had reduced the amount of stoping ore which could be delivered to the plant) affected production between August and October The necessary spare parts were delivered to site in October followed by a new underground truck and underground loader in November and late December respectively.

The Company also reported on 29 October 2012 its intention to strengthen the mine's management team with the recruitment of a technical director for Asacha, following the appointment of two new underground mining engineers and a mining geologist in October. The new technical director commenced work at site in November.

TSG believes that these appointments of experienced personnel, together with the new equipment, will consolidate the steady improvement in the mine's performance at the end of the fourth quarter. The Company is cautiously optimistic that ore dilution can be reduced further through planned changes in the mining methods, in particular, introduction of additional supports and/or backfilling.

Mining activity is now focused on increasing the volume of stoping ore, since the 4,100 metres of mine development in 2012 included the preparation of stoping areas to be mined in 2013. TSG will report Asacha's first quarter 2013 production in April 2013.
