Caledonia Mining Corporation13 March 2006 Caledonia Mining Corporation Caledonia Acquires Additional Properties Adjoining its Rooipoort (PGE/Au/Ni/Cu)Project, South Africa, virtually doubling the Rooipoort Project area. Toronto, Ontario - March 13 2006: Caledonia Mining Corporation ("Caledonia")(TSX: CAL, NASDAQ-OTCBB: CALVF, AIM: CMCL) is pleased to announce that it hasconcluded an agreement, on behalf of its wholly owned South African subsidiarycompany Eersteling Gold Mining Company Limited ("EGMC"), with FalconbridgeVentures of Africa (Pty) Ltd ("Falconbridge") (a subsidiary of FalconbridgeLimited), to acquire a 100% interest in Falconbridge's prospecting rightscovering the farms Moordrift 289KR, Jaagbaan 291KR, and portions of Grasvally293KR, a total area of 4,315.81 hectares. Eersteling's current rights cover4,404.84 hectares on Rooipoort 46KS and portions of Grasvally 293KR. Thisacquisition effectively doubles the area of Caledonia's Rooipoort Projectunderlain by Bushveld Complex rocks with proven PGE potential. Highly Prospective PGE Terrain:These properties are situated at the southern end of the highly prospectivenorth limb of the Bushveld Complex, some 50km south of the Anglo Platinum openpit mining operation on the Platreef. Intensive exploration is being conductedalong the entire length of this 110km prospective zone by a number of companies,viz. AfriOre, Anooraq, Pan-Palladium, Ivanhoe Nickel & Platinum, PTM and AIMResources. The Moordrift, Jaagbaan and Grasvally farms adjoin the western and southernboundary of Caledonia's Rooipoort (PGE/Au/Ni/Cu) Project area and contain thedown dip extension of PGE/Ni/Cu mineralization that was recently discovered byCaledonia on the western side of Rooipoort farm (Central Target Area) (Fig. 2).(Also please see Caledonia website Project Status Report dated December 9 2005and the NI 43-101 Independent Resource Report on portion of the mineralized, 61/2 kilometre long, Eastern Target Area. Falconbridge conducted limited exploration drilling (see Table 1 for details of3 holes) on the Rooipoort boundary and on Grasvally and intersected the down dipextension of the mineralisation intersected by Caledonia, described above.

The location of these holes, and the results of this drilling canbe found in the Investor Centre on the Caledonia website (www.caledoniamining.com) under Technical Reports, in the document titled"Rooipoort PGE/Au/Ni/Cu Project - Falconbridge Property Acquisition - DrillingResults" This reef horizon is characterized by a highly favourable approximately 3:1 Pt:Pd ratio. Falconbridge concentrated on following up their best intersection inhole MD03-02 (6.86 m @3.38g/t Pt; 1.23 g/t Pd; 0.57 g/t Au; 0.23% Ni; and 0.29%Cu) as a probable conformable structure. Caledonia's interpretation of rockalteration and of the aeromagnetic data indicates the possibility of moreirregular vertical "ballroom type" structures that could have been missed byFalconbridge vertical drilling for a planar west dipping reef. Caledonia is planning to evaluate the near surface, up-dip extensions of thismineralization on the Rooipoort and Grasvally properties with the initial aim ofdelineating an open pit resource as soon as the necessary permits have beengranted by the South African authorities. This property and data acquisition opens up an extensive new target area of PGEmineralisation and greatly enhances the potential economic viability ofCaledonia's Rooipoort PGE/Au/Ni/Cu Project by more than doubling the areaunderlain by highly prospective PGE/Au/Ni/Cu mineralised stratigraphy alreadyidentified by drilling. Application to the South African authorities to transfer the Falconbridge rightsto Eersteling will commence immediately.
