OPEN PIT AND PROCESSING OPERATIONS
The extraction of excess open pit waste material is nearing completion. During the quarter ended 30 September 2011, the Sekisovskoye mining operation averaged 450,000t of material movement each month, totalling 1.368Mt. This increase of 35%, compares with the 1.015Mt excavated in Q3 2010. Substantial improvements to the operations have been achieved over the past six months and once the excessive waste quantities have been removed, the mining operations at Sekisovskoye will be well placed for 2012.
The focus on waste extraction during July meant that less ore was mined. As a result, a significant proportion of ore from the low grade stockpile was treated, resulting in the exceptionally low overall gold grade in that month. In August and September, more regular mining activities resumed so that less ore from the low grade stockpile was treated, resulting in an improved grade of feed to the process plant.
The process plant treated 216,491 tonnes of material and produced a total of 6,026 ounces of gold and 10,887 ounces of silver.
UNDERGROUND
The decline access to the underground deposit advanced according to plan during the quarter with no safety incidents. The development of the underground project remains on target for extraction commencing in Q4 2011. Two separate underground tunnels were completed to provide drill chamber access for the ore zones.
DRILLING
As part of Hambledon’s 25,000m drill programme, the results from some forty-seven holes have been announced, totalling approximately 8,000 metres. The drill results released to date have been above expectations. There has been an expansion of resources from all ore zones, notably from Ore Body 11 which will be the first zone to be mined. The next set of drill results will be announced shortly.
