Q1 GOLD PRODUCTION
HIGHERĀ GOLDĀ PRICESĀ ANDĀ CASHĀ COSTS, LOWER PRODUCTION
Avocet Mining PLC ("Avocet" or "the Company")Ā announcesĀ firstĀ quarterĀ FY2009Ā gold productionĀ of 28,022 ouncesĀ toĀ 30Ā JuneĀ 2008Ā from the Company'sĀ continuingĀ operations at Penjom inĀ MalaysiaĀ and North Lanut inĀ Indonesia. All gold sales were into the spot market during the quarter with an average realised price of US$891/oz compared with US$667/oz for the same period last year.Ā
Ā
Initiatives are in progress to accessĀ the higherĀ gradesĀ at Penjom,Ā close to the shear zoneĀ and to the south of the main Kalampong pit,Ā and toĀ improveĀ recovery ratesĀ atĀ North Lanut. The CompanyĀ expects these initiatives to improve production and unit costs, compared withĀ the Q1 figures, whichĀ are notĀ seen asĀ representative of the cash cost and gold production profile anticipated for theĀ fullĀ financial year to March 2009. Nevertheless,Ā depending on the timing of these initiatives,Ā production and cost levels for the second quarter to 30 September 2008Ā mayĀ be broadly similar to those experienced in the first quarter.
Appendix 1 sets out key operating statistics including production and cash costs by quarter for this year and the prior year for both Penjom andĀ North Lanut. Appendix 2 sets out Penjom's waste and ore volumes and mining cost per tonne for each year, as well as the calculation of stripping costs deferred in the first quarter of FY2009.
Penjom,Ā Malaysia
Gold productionĀ in the first quarter of FY2009Ā at Penjom of 18,729 ounces was 19% belowĀ theĀ corresponding period ofĀ the prior yearĀ andĀ 13% below the preceding quarter. The average grade milled of 3.44 g/t was 39% below the 5.62 g/t in the corresponding period,Ā which included mining of some high grade areas that pushed the milled grade to 7.14 g/t in April 2007. This variability reflects theĀ complex, nuggetyĀ natureĀ of the Penjom orebody. Ā Mining continuesĀ to focus onĀ accessing moderate to highĀ grade ore and on accelerating theĀ push back of the east wall. The majority of the grade shortfall was compensated by tonnes milled being 36% above the prior year following the successful upgrade of the Penjom plant in January this year. Penjom's cash cost per ounce of US$481/oz wasĀ 64% higher than the previous year's US$293/oz. This isĀ partly because of lower production,Ā but mainlyĀ due toĀ significantlyĀ higher prices for consumables,Ā notably diesel,Ā for whichĀ the mine has seen a year on year increase of 80%Ā in unit prices, equivalent to US$61/oz. Diesel accounted for 29% of total costs at the mineĀ during the first quarter of the current yearĀ comparedĀ withĀ 19% in the prior year. In addition, the increase in gold prices resulted in a US$17/oz higher royalty costĀ reflectingĀ theĀ royalty payable to the Malaysian government atĀ 7% of revenue.Ā
In the second half of the year a higher proportion of mining is scheduled to take place in theĀ area to the south of the main Kalampong pitĀ following completion ofĀ a temporary stream diversionĀ toĀ allow mining of this area where grades are expected to be higher than those achieved in the first quarterĀ of FY2009.
NorthĀ Lanut,Ā Indonesia
North Lanut's gold productionĀ in the first quarter of FY2009Ā of 9,293 ounces was 41% below theĀ corresponding period of theĀ prior yearĀ when the mine processed oxide oresĀ which yield a higher recovery;Ā andĀ 35% below the preceding quarterĀ when transitional oresĀ benefited from high levels of secondary leaching. This year's Q1 productionĀ reflected an 18% reduction in tonnes irrigated in order to allow longer leach timesĀ required to improve goldĀ recovery of more transitional and sulphidic materialĀ processedĀ this year.Ā The change to longer leach times has led to a lower reportable gold recovery ofĀ 38% in theĀ FY2009Ā first quarter comparedĀ withĀ last year's first quarter recovery of 51%; however,Ā additional recovery is expected from the ore currently under leach. The grade of ore treated for the quarterĀ at nearly 2 g/tĀ was similar to last year. North Lanut's cash cost per ounce of US$601/oz was nearly double the previous year's US$314/oz owing to lower production compounded by diesel and consumable price inflation similar to levels seen at Penjom.Ā Diesel accounted for 19% of total costs atĀ North LanutĀ during the first quarter of the currentĀ yearĀ comparedĀ withĀ 13% in the corresponding quarterĀ last year.Ā
In the second half of the year, recovery andĀ goldĀ production are scheduled to benefit from:
*Ā the new HLP3 leach pad which will provide separate cells for each different type of ore;
*Ā the crushing of ore following the commissioning of a new mobile crushing unit; and
*Ā a plant upgrade, together with a number of other initiatives that are ongoing to reduce costs and improve gold production.
Jonathan Henry, Chief Executive Officer, commented:
"Short term operational issuesĀ of lower treated grades at Penjom and lower recovery atĀ North LanutĀ have reduced production comparedĀ withĀ levels reportedĀ for the first quarter ofĀ last year. Cash costsĀ per ounce, as with manyĀ goldĀ mining operations globally,Ā have been additionally hit byĀ significantĀ priceĀ inflation of keyĀ consumables, especially diesel.Ā Ā WeĀ anticipate the benefit of the measures under way toĀ improveĀ production from both mines, with a corresponding decrease inĀ unit costs,Ā will become apparentĀ during the second half of theĀ financialĀ yearĀ to 31 March 2009."

Notes to Editors
Avocet is a mining company listed on theĀ AIMĀ market of the London Stock Exchange (Ticker:Ā AVM). The Company's principal activities are gold mining and exploration in Malaysia (as 100 per cent owner of the Penjom mine, the country's largest gold producer), and Indonesia (as 80 per cent owner of the North Lanut gold mine and Bakan project in North Sulawesi). The Company has a number of other advanced mining and exploration projects inĀ South East Asia.
Background to operations
The Penjom gold mine isĀ Malaysia's largest gold producer and was developed by Avocet after applying modern technology to grass roots exploration in an area of historic mining. The mine was commissioned in December 1996 with reserves of 223,000 ounces. Successful resource development, particularly over the last five years, means Penjom has produced over one million ounces of gold to date and still has nearly one million ounces of resources. This resource is expected to grow further following a drilling programme expected to total 70,000 metres over the next year which includes deep drilling to help assess the potential for underground mining in the near future, where areas of high grade ore are known to exist. In November 2005, the Company announced a significant increase in Penjom's life of mine plan to over half a million ounces, which resulted in the design of a much larger pit to allow the additional ounces to be mined. Over the last year Penjom has expanded its mining and plant capacity accordingly. Avocet was able to overcome initial problems of highly carbonaceous ore at Penjom by developing unique processing systems including complex gravity circuits and resin-in-leach (RIL) technology. These processes have potential applications at other carbonaceous orebodies.
TheĀ North LanutĀ gold mine in North Sulawesi, Indonesia, was developed by Avocet from the exploration stage and has produced nearly 200,000 ounces since it was commissioned in 2004, including record production in the year ended 31 March 2008 of 74,183Ā ounces. Recent high grade exploration drilling results indicate the potential for a significant increase in resources and extension in the mine's life. In 2002 Avocet purchased its 80 per cent interest inĀ PT Avocet Bolaang MongondowĀ (PT ABM), an Indonesian company holding a 6th generation Contract of Work (CoW), from Newmont Mining Corporation. TheĀ North LanutĀ gold mine is located within the CoW, which includes exploration and mining rights over approximately 50,000 hectares in an area highly prospective for gold. An Indonesian company, PT Lebong Tandai, owns the remaining 20 per cent.
