Latest drilling results from Sekisovskoye underground project, Kazakhstan
19 January 2012
Hambledon Mining Plc (AIM: HMB), the Kazakhstan gold mining and development company, continues to advance its underground drill programme to validate and expand the geological resources at Sekisovskoye and today reports the results of a further four drill holes.
The results from the programme during December 2011 following a period of six weeks of planned maintenance of the drill rigs are as follows:
A cumulative total of sixty seven holes drilled to date over 9,000 metres The main intersections since the last update include: Hole D65 - 9m at 4.86g/t Au, Hole D66 - 2m at 3.5g/t Au, Hole D67 - 4m at 2.62g/t Au,To date, sixty seven drill holes have been completed in the upper levels of the underground ore zones and the results are consistent and in many areas exceed the geological and mineral resource modeling previously carried out.
The assays were carried out in the Altai Ken-Bayitu laboratory with independent verification to be undertaken by the Alex Stewart Group in Karabalta, Kyrgyzstan.
The Sekisovskoye deposit comprises approximately ten large mineralised zones intermingled with numerous narrow and sinuous mineralisation zones. The zones of mineralisation show wide variation in thickness from 0.35 metres to 30 metres, with a weighted average of 5.5 metres. The zones display a localised pinch and swell structure, with variable gold and silver content. The large average width makes for easier and lower cost mining.
The ore body to be mined in 2012 is ore body number 11 where mining started in Q4, 2011. The drill results and mined grade [including dilution] compare favorably and provide robust confirmation of the geological model.
Good progress has been in made in expanding the underground mining zones with three levels being mined at present and a fourth due to commence in early February, 2012. The ground conditions have to date been good and water inflow within the excavation zones minimal, providing confidence that the bulk mining methods to be employed later will be technically feasible.
A significant programme of geological and rock mass characterisation will take place concurrently to ensure that the mining operation advances in tandem with sound engineering knowledge guiding the development of the project. A team of UK geologists will be visiting the mine site in mid-2012 for three months to carry out additional and specific structural mapping to add to the rock characterization studies supervised by Golder Associates, UK.
