Caledonia Reduces Exercise Price of Outstanding Options

TORONTO, ONTARIO--(Marketwire - Sept. 4, 2009) - Caledonia Mining Corporation ("Caledonia")
(TSX:CAL)(OTCBB:CALVF)(AIM:CMCL) proposes to reduce the exercise price of 32,580,000 share purchase
options currently outstanding from exercise prices averaging approximately $0.1719 per share to $0.07
per share. These share purchase options are in favour of directors, officers and service providers.
This reduction recognises the fact that the existing options are all substantially "out of the money"
due to the reduced trading price of Caledonia's shares which, in common with most other publicly
traded shares, has been adversely affected by the recent economic and market downturn. The existing
option arrangements no longer provide an incentive to directors, officers and service providers and is
the reason for this proposal.

The Toronto Stock Exchange rules require that options with reduced exercise prices cannot be exercised
at the reduced prices until the reduction has been approved by the shareholders. The reduction will be
submitted to the shareholders for approval at the next general meeting of Caledonia's shareholders.
