Caledonia Mining Corporation18 November 2005 CALEDONIA MINING CORPORATION 2005 DRILLING PROGRAM COMPLETED ON CALEDONIA'S MULONGA PLAIN JOINT VENTURE Toronto, Ontario - November 18, 2005: Caledonia Mining Corporation ("Caledonia")(TSX: CAL, NASDAQ-OTCBB: CALVF, AIM: CMCL) and its joint venture partner MotapaDiamonds Inc. ("Motapa") (TSX-V: MTP) announce completion of the 2005 drillprogram on the Mulonga Plain joint venture in western Zambia. Ten, out of an original 11, airborne gravity and magnetic targets were tested inthe program, one hole was abandoned due to poor drilling conditions. Basaltbasement was intersected in each of the holes at depths ranging from 87 metersto 173 meters with no kimberlite intercepts reported from any of the holes.Motapa has defined four prospective regions within the extensive Mulonga Plainanomaly through prior heavy mineral sampling, airborne magnetics andreconnaissance drilling. The 2005 drill program was designed to test theeasternmost of these prospective regions and followed on from completion andinterpretation of an airborne gravity survey in late 2004. Core samples from this drill program are enroute to Cape Town for kimberliteindicator mineral recovery and analysis. These results are anticipated in lateJanuary 2006 and will be used to formulate plans for ongoing work on theeasternmost prospective region of the Mulonga Plain anomaly. Commenting on the results, Motapa's CEO Dr. Larry Ott noted: "The extensiveMulonga Plain diamond and kimberlite indicator mineral anomaly remains highlyprospective for discovery. This program has provided an initial drill test ofone of four well defined indicator mineral dispersions. The remaining threeareas, in the central and western portions of the Mulonga Plain remainessentially untested and results of this program should add considerably to ourunderstanding of kimberlite indicator mineral dispersion within the MulongaPlain and better constrain likely source kimberlite areas." In western Zambia, Caledonia has a 40% interest in three prospecting licensescovering approximately 3.3 million hectares. These licenses collectively make upthe Mulonga Plain Joint Venture. Motapa is the joint venture partner andoperator on the property. Motapa has rights to earn an additional 15%participating interest by continuing to fund Caledonia's share through tocompletion of a feasibility study.
