Avocet Mining PLC06 February 2008 EXPLORATION UPDATE AVOCET RECEIVES POSITIVE GOLD GRADES IN DRILLING AT MANGKALUKU, SOUTH SULAWESI, INDONESIA Avocet Mining PLC ("Avocet" or "the Company") announces positive gold grades inscout drilling from the Mangkaluku prospect in South Sulawesi, Indonesia. Sinceannouncing significant gold trenching results on 30 August and 22 November 2006,the Company has gained a 90% effective beneficial interest in a 181 km2 KuasaPertambangan Explorasi or national exploration license covering the SouthSulawesi prospects. Avocet has now completed 12 drill holes (1,832 metres) evaluating the two mostsignificant vein systems, which strike ENE over a distance of 600 metres withwidths of up to 200 metres and NNE over a length of 500 metres with widths of upto 100 metres. Drill hole locations are laid out in the figure that can befound in the announcement on the Company's website. Table 1 summarises the significant intercepts from this scout drillingprogramme, which include 2m @ 117 g/t Au from 34 metres depth (MLD005) and 12m @3.51 g/t Au from 117metres (MLD007). Native gold is visible in seven of thetwelve holes. These results are highly encouraging and warrant follow-up withbroad infill drilling to define the resource potential at Mangkaluku. Furtherdrilling work will remain subject to the usual permitting processes. A review of drill core has identified at least four phases of veining hosted byphyllic-altered monzodiorite. Two phases of sheeted quartz-arsenopyrite+/-carbonate veining are clearly associated with gold mineralisation. These veinsoccur as narrow, high grade sets (notably 2m @ 117 g/t Au) that bulk out towider, but lower grade zones enveloping narrow internal waste zones (including12m @ 3.51 g/t Au). Jonathan Henry, Chief Executive Officer, commented: "These encouraging results highlight the potential of the Mangkaluku prospectand are a further demonstration of our exploration team's ability to find highlyprospective gold projects. We look forward to the next phase of work at SouthSulawesi, and at the other projects where we have recently announced successfuldrilling results, as part of our strategy of significantly growing the Company'sresource base."
