                                  NEWS RELEASE

          SUCCESSFUL MINI-BULK SAMPLE OF GOEDGEVONDEN KIMBERLITE PIPE,
               AND ADDITIONAL EXPLORATION RIGHTS ACQUIRED OVER THE
           SYFERFONTEIN KIMBERLITE PIPE AND ADJACENT AREAS OF INTEREST

                          JUNE 12TH 2002, 09.00 AM. EST

Caledonia Mining Corporation ("Caledonia") of Toronto (TSX: CAL and NASDAQ -
OTCBB: CALVF) is pleased to report that it has completed a mini-bulk sampling
program on its Goedgevonden kimberlite pipe in the Klerksdorp area of South
Africa and that it has also acquired the exploration rights over the nearby
Syferfontein kimberlite pipe and other adjacent areas of interest.

GOEDGEVONDEN MINI-BULK SAMPLING PROGRAM

A mini-bulk sample was collected from seven RC holes drilled on the Goedgevonden
kimberlite pipe. Three holes were drilled to 150 m, and one hole to 120m, in the
centre of the kimberlite and the remaining three holes were drilled to delineate
the pipe in more detail. All holes entered kimberlite at approximately 6 metres
and the four deep holes above were stopped while still in kimberlite. A total of
56 tonnes was collected and processed by a Van Eck and Lurie dense media
separation ("DMS") plant. The Goedgevonden pipe was confirmed to be
diamondiferous and sufficient gem quality diamonds, including a number of pink
stones, were recovered to warrant a subsequent 8,000 to 10,000 tonne bulk
sampling program which will commence in the third quarter 2002. Based on results
of this second program a more extensive bulk sample of up to 40,000 tonnes would
be required before any production decision could be made.

SYFERFONTEIN KIMBERLITE

Caledonia has acquired the exploration rights over the Syferfontein kimberlite
pipe on the farm Syferfontein 376IP, approximately 1km NE of the Goedgevonden
pipe. Exploration reports of work conducted by others over the Syferfontein
kimberlite in 1997 confirm that it is diamondiferous and recommend a mini-bulk
sampling program to evaluate the grade in the upper levels of the pipe.
Caledonia plans to initiate this program in the third quarter. Future
exploration programs would be based on the results of this sample.

Caledonia also plans to drill two other pipe-like targets which they have
identified within their exploration area.
