In December 2004 we announced a 27% increase in Penjom's gold resources. Thisfollowed a successful infill drilling campaign designed to improve ourconfidence in the mine's resource model which led to an interim increase in openpit reserves. This programme also improved our understanding of the geologicalcontrols on the deeper parts of Penjom's ore bodies and of the potential forexpanding open pit mining with the possibility of an underground operation.Underground mining was shown to be viable with the completion in March 2005 ofthe E-Drive into the east wall of the main Kalampong pit which also facilitatedthe exploration of areas difficult to drill from surface. Since the December 2004 announcement we have conducted an additional 21,943metres of reverse circulation drilling up to the end of May 2005. This has beendesigned to evaluate extensions to the open pit reserve beneath the central andnorthern portions of the current Kalampong pit. This drill programme is ongoingand is expected to be completed in August this year. Drilling has identified several high-grade zones of mineralisation controlled byNS- and NW-striking faults beneath the Penjom Thrust. Table 1 summarises theresults, above 20 gram metres, from this drilling programme that lie up to 100metres below the current pit design. These include 4m at 45.6 g/t Au, 6m at 38.8g/t Au, 3m at 56.9 g/t Au and 6m at 25.7 g/t Au (reported using a top cut of 100g/t Au). Table 2 summarises the better drilling intercepts, above 20 gram metres, withinthe current pit design. These results continue the trend of the last two yearswhere additional drilling has shown higher grades than modeled. These include 9mat 37.8 g/t Au, 7m at 32.4 g/t Au, 9m at 18.1 g/t Au and 11m at 12.8 g/t Au(reported using a top cut of 100 g/t Au). We anticipate that the current drilling programme will result in a significantexpansion to the resource and open pit reserve at Penjom which we hope toconfirm during the second half of 2005. It is worth noting that the Company hasincreased Penjom's resources by 367,100 ounces and its reserves by 245,300ounces since the commencement of the first comprehensive exploration programmetwo years ago and thereby replaced production during that period. This equatesto a 54 per cent increase in resources and a 58 per cent increase in thelife-of-mine production schedule since 31 March 2003, when there was 423,650ounces still to be mined. It also highlights the large portion of resourceincreases converted to reserves for future gold production. The Company has also been reviewing the gold resources at its 100 per cent ownedBuffalo Reef prospect, approximately 40km from Penjom. Table 3 summarises thesignificant intercepts from a 3,223-metre drill programme conducted in the firstquarter of 2005. These include: 12m at 5.19 g/t Au, 10m at 4.67 g/t Au, 8m at4.94 g/t Au and 3m at 10.6 g/t Au. The primary objective of this drilling was tocollect bulk samples of primary ore for metallurgical test work. This test workis ongoing. Elsewhere in Malaysia, district and regional scale exploration has been ongoingsince the second half of 2004 with a review of large-scale geochemical,geophysical, geological and remote-sensed databases. The Company has nowidentified several promising targets and conducted preliminary exploration atthe most prospective. This has resulted in the discovery of one new deposit withup to 3.73 g/t Au in quartz veins over an extensive area and the flagging offive other properties worthy of further exploration. It also highlights theprospectivity of peninsular Malaysia. Avocet is a mining company listed on the AIM market of the London StockExchange. The Company's principal activities are gold mining and exploration inMalaysia (as 100% owner of the Penjom mine, the country's largest goldproducer), Tajikistan (as 75% owner of JV Zeravshan LLC, Tajikistan's principalgold mining company), and Indonesia (as 80% owner of the North Lanut mine inNorth Sulawesi). The Company will be announcing its preliminary results for theyear ended 31 March 2005 on 13 July 2005.________________________________________________________________________________ For further
