Item 5. Other Events
------------
Golden Star Resources Ltd. ("Golden Star") and Guyanor Ressources S.A.
("Guyanor") announced the results from the bulk sampling program undertaken by
Guyanor and its joint venture partner Rio Tinto Mining and Exploration Limited
on the Dachine Diamond project in French Guiana.
The program was designed to sample a large volume of material from various zones
of the Dachine ultramafic body to yield a parcel of diamonds in order to confirm
the presence of gem quality stones. The partners installed a plant that
processed 547.85 tonnes (dry) of weathered diamond-bearing rock and produced
15.95 tonnes (dry) of concentrate that was forwarded to the Nomos laboratory in
Brazil for final diamond recovery and evaluation.
Diamonds were found in 18 out of 23 samples processed. Using a cut-off size of 1
mm, grades varied from 0.06 to 10.48 carats per hundred tonnes. The largest
stones were found in the 1.7 to 2.36 mm size range, with an average weight of
0.066 carats. However, the majority of the stones occurs in the ranges of 1 to
1.18 mm and 1.18 to 1.70 mm. Stone colors varied from white to light brown and
rarely greenish/yellow. Stones are translucid to transparent, but often masked
by large quantities of inclusions. The dominant shapes are irregular, with small
quantities of cubic and octahedral stones. Stones are often intensely
reabsorbed.

These results are considered disappointing and no further project work is
planned at this time. Rio Tinto has advised Guyanor that, given the results
obtained, it intends to withdraw from the project and terminate their joint
venture. Guyanor will probably continue evaluating the remaining targets in the
region, notably Vitoria and Palofini, where diamonds were found early this year.
A new exploration permit has been applied to cover these areas.
