KIKERK LAKE The Kikerk Lake property is located in the Coronation Gulf region of Nunavut and hosts the diamondiferous Potentilla and Stellaria kimberlites, identified on the property in 2001 and 2002 respectively. The winter portion of the 2003 program announced by Ashton and Caledonia on March 7, 2003 has been completed and three electromagnetic anomalies associated with indicator mineral dispersions and underlying lakes approximately one km west of Potentilla were tested by drilling. At one anomaly, two angle holes drilled at inclinations of 46 degrees and 65 degrees from horizontal intersected approximately 0.6 m and 0.3 m of kimberlite respectively. This anomaly is located about 1.2 km west of the Stellaria kimberlite associated with a two km long linear structure. No kimberlite was intersected at the other two anomalies. Exploration on the Kikerk Lake property will continue during the summer and field activities will include follow-up on a number of unexplained indicator mineral and geophysical anomalies through heavy mineral sampling, ground geophysical surveys and prospecting. Exploration on the Kikerk Lake property is governed by an option and joint venture agreement among Ashton, Caledonia and Northern Empire Minerals Ltd. Ashton has a 52.5 percent interest in the property and has exercised its option with Caledonia to increase its interest to 59.5 percent. Northern Empire has a 30 percent joint participating interest and is funding the current program. Ashton as operator of the programs is responsible for the design, conduct, verification and quality assurance of the analytical results. GENERAL UPDATE The Barbrook Gold mine in South Africa has been returned to commercial production and mined tonnage continues to increase. Both Barbrook and the 96% owned Eersteling Gold Mine have received their permanent mining authorizations from the South African Department of Minerals and Energy ("DME"), who have also issued Eersteling with a Prospecting Permit for the Rooipoort Platinum Project. At Eersteling, prior to commencing the dewatering of the first three shafts, water levels and samples have been taken from the surrounding farm boreholes and discussions are being held with the DME and the Department of Water Affairs regarding the storage and subsequent use of this pumped water by the mine. A comprehensive desk study on Rooipoort, based on airborne geophysics and the down dip drilling on the adjacent farm undertaken by Anglo Platinum has been completed. This study has confirmed the likely presence of both the Merensky and the UG-2 platinum group metals on the property. A ground geophysics program will commence in early June and subject to these results will likely be followed immediately by a drilling program.
