Alexander Mining PLC05 January 2007 Alexander Mining plc 5 January 2007 New Resource Statement for Leon Copper Project • Deposit resource model estimate predicts a total oxide resourcecontaining a 22% increase in contained copper for El Cobre and 16% for El Plomo. New Resource Statement for Leon Copper Project, Salta Province, NW Argentina Following the release in July 2006 of a JORC Code resource statement, preparedby geological consultants A.C.A. Howe International Limited ("Howe"), for the ElCobre and El Plomo deposits at the Leon copper project, north-west Argentina, atHowe's recommendation Alexander Mining plc ("Alexander", "the Company) conductedadditional diamond core drilling at both deposits between July and November2006. This work was designed so that some areas classified as inferred may beupgraded to the indicated category under the JORC Code and further to define andenhance the boundaries of the ore envelopes. Between July and October 2006, atotal of 12 holes for 1,085.69m were drilled at the El Cobre deposit and 51holes for 3,826.17m at the El Plomo deposit. Re-estimation of resources at El Cobre and El Plomo was undertaken by Howe usingthe new drilling data. As a result, the updated resource statement for the ElCobre and El Plomo deposits is as follows: El Cobre Deposit Tonnes, Mt Copper, % Silver, g/t Copper, t Silver, Moz Indicated Oxide Resource 2.25 0.94 20.02 21,080 1.45 Inferred Oxide Resource 0.43 0.69 12.37 2,940 0.17 Total Oxide Resource 2.67 0.90 18.79 24,020 1.62 El Plomo Deposit Tonnes, Mt Copper, % Silver, g/t Copper, t Silver, Moz Indicated Oxide Resource 2.90 0.46 17.63 13,330 1.65 Inferred Oxide Resource 0.86 0.44 15.75 3,750 0.43 Total Oxide Resource 3.76 0.45 17.20 17,080 2.08 Note: Copper grade cut-off of 0.20% used; totals may be subject to roundingerrors. Compared with the statement released in July 2006, the El Cobre deposit resourcemodel estimate predicts a total oxide resource containing 14% more tonnes, 7%higher copper grade and a 22% increase in contained copper. Similarly, at theEl Plomo deposit, the resource model estimates a total oxide resource containing22% more tonnes, 6% lower copper grade and a 16% increase in contained copper. Leon Regional Exploration Programme - Arbol Solo Following the announcement in December 2006 of encouraging initial explorationresults at the Arbol Solo copper property, 23km due south of Leon, as expected,work is temporarily halted because of seasonal rain. An intensive campaign willcommence shortly to follow-up on this exciting new discovery.
