Sekisovskoye Underground Project â€“ Drilling Update

30 March 2011

Hambledon is currently undertaking a substantial underground drill programme to validate and expand the geological resources at Sekisovskoye.

Key results from the programme to date are as follows:

Eight drill holes completed
Over 1,700 metres drilled
Significant intersections include:
- Hole D121 â€“ 33m at 4.78 g/t Au
- Hole D121 â€“ 60.4m at 5.6 g/t Au
- Hole D122 â€“ 8m at 10.75 g/t Au
- Hole D122 â€“ 44m at 5.74 g/t Au
- Hole D124 â€“ 26.3m at 5.13 g/t Au
- Hole D125 â€“ 33m at 4.5g/t Au

As announced on 10 January 2011, Hambledon has committed to, and commenced, an 18 month drill programme of approximately 25,000 metres to be completed at an average rate of 1,500 metre per month. An extension of this drill programme will be undertaken once the underground decline is constructed below the existing 320 metre level, which sits some 85 metres below the base of the current open pit.

To date, 8 drill holes have been completed and the results have confirmed the geometry of the resource and validity of the current resource model. Significantly, the drill holes have also expanded the known dimensions and increased the volume of ore in zone 8, one of the main zones, by over 22%. Further details of the drill hole results are included in Appendix 1 below.

The analytical works were carried out in the Altai Ken-Bayitu laboratory with independent assay verification to be undertaken by the Alex Stewart Group in Karabalta, Kyrgyzstan.

The Sekisovskoye deposit is in the Rudny Altai metallogenic belt and is one of seven gold fields in East Kazakhstan. The host rocks are very coarse grained, altered, igneous breccia zones of variable composition within granitoid intrusives. The breccias range up to 700 metres in width by 160 metres in breadth, with steep northeasterly dips, and extend to drilled depths greater than 950 metres. The breccias are cut by mostly concordant dykes of various compositions and a system of cross-cutting faults. Gold mineralisation is restricted to the igneous breccias between barren igneous dykes dipping northeast. The zones of mineralisation show wide variation in thickness from 0.35 meters to 30 metres with an average of 2.2 metres and localised pinch and swell structure, with variable gold and silver content.

The drill results confirm the high grade mineralisation with average in-situ grades between 5-6 g/t of gold, and 6-7 g/t of silver. The mined grade post dilution is expected to average 4.2 g/t of gold.

The current geological model and JORC resource, which is currently in excess of 2.0M ounces of Gold and 2.9M ounces of Silver, is being updated and will be released in conjunction with publication of the Companyâ€™s annual report and accounts for the financial year to December 2010 in Q2 2011. Further resource updates will be announced with the drill results.

A revised underground mine design and infrastructure engineering study is being undertaken by Golders Associates Limited which will enable updated mine reserves to be issued in December 2011.
