                              BARBROOK MINE UPDATE

                             JULY 9TH 2002, 10.00 AM

Caledonia Mining Corporation ("Caledonia") of Toronto (TSE: CAL and NASDAQ -
OTCBB: CALVF) is pleased to report that it has completed its geological
re-evaluation of the Taylor's section of its 100% owned Barbrook Mine located in
the Mpumalanga Province of South Africa. The Barbrook mine was placed on care
and maintenance in mid 1997 after the fall in the gold price and has recently
been returned to limited production.

Barbrook is now focusing on the immediate re-commencement of commercial scale
mining and process operations now that the ore available for mining startup has
been re-defined. Mining will initially be concentrated in the Taylor's west area
with the intention to reduce internal waste generation which previously resulted
in severe ore grade dilution to the mill.

The metallurgical circuit at start-up will include Caledonia's new Pre-Ox
process and the resin gold recovery process developed by MINTEK. MINTEK are
currently determining the requirement for the conversion of Barbrook's existing
Carbon-in-leach ("CIL") into a resin-in-leach ("RIL") section and the
requirement for a resin elution, regeneration and electrowinning sections.
Confirmatory testwork on Taylor's ore by MINTEK in 2001 showed that the
combination of Pre-Ox and RIL processes resulted in approximately a 20% higher
gold recovery than the CIL process previously used at Barbrook.

It is planned to initially commence mining and processing at 3,000 tonnes per
month and thereafter to increase this progressively to 12,000 tonnes per month
or higher. During the 1997 mining and plant throughput at Barbrook exceeded
17,000 tonnes per month. However this rate was obtained at the expense of gold
grade dilution, and therefore the mining rates will be restricted to control
dilution and ensure higher feed gold grades to the plant.

Preliminary production schedules and mine plans are being prepared at present
and recommissioning work has commenced on both the underground workings and the
metallurgical plant in preparation for the resumption of production later this
year. Several mining sequences are being considered and once these have been
optimized the detailed production plans will be announced, most likely in early
September.
