Sunrise Diamonds plc, ('Sunrise Diamonds' or 'the Company') is pleased to
announce that it has recovered five micro-diamonds from a drill core sample of
Kimberlite 45 at its Kuusamo exploration area in northern Finland where the
Company has discovered a new kimberlite cluster, with five separate kimberlites
identified to date.

The results confirm the diamond prospectivity of the Earth's mantle beneath the
Kuusamo project area, previously only inferred from indicator mineral chemistry,
and vindicate the Company's exploration strategy.

The five micro-diamonds were recovered from a sample of Kimberlite 45 weighing
25.6kg analysed at Kennecott's Laboratory in Canada (accredited to ISO/IEC
17025). All are fragments and have a longest axis between 0.27mm and 0.39mm.
Four are white and transparent with minimal resorption whilst one is grey and
transparent with no evident resorption.

Samples from a second kimberlite, Kimberlite 47, did not return micro-diamonds
but mineralogical work during the summer reveal it to be a higher-level
diatreme-type kimberlite, unlike Kimberlite 45 and the earlier discoveries at
Kuusamo which are all hypabyssal-type occurrences. Kimberlite 47 thus indicates
that the discovery of larger kimberlites is possible in the Kuusamo area as not
all of the pipes are eroded to their hypabyssal roots.

Till sampling during the summer has identified several trains of kimberlite
indicator minerals that need to be followed up with further sampling and
drilling. These include mineral trains containing diamond-diagnostic G10
pyrope-garnets, kimberlitic ilmenites, chrome diopsides and chromites and are of
a notably higher order than those associated with the kimberlite discoveries
made to date.

Kimberlites 45 and 47 were drilled solely on the basis of their magnetic
signature. The magnetic data from the areas surrounding these kimberlites has
now been re-processed and this has identified additional priority drill targets
in the vicinity of Kimberlites 45 and 47.

Commenting on the results, Sunrise Chairman Mr. Patrick Cheetham said today 'The
discovery of micro-diamonds at Kuusamo is a major milestone for Sunrise and has
been achieved on a very limited budget. We are look forward to the very real
possibility of further discoveries in this exciting new kimberlite field.'




ABOUT SUNRISE DIAMONDS

Sunrise Diamonds plc is exploring for diamonds in the Karelian Craton in Finland
- a geological block that is host to world-class diamondiferous kimberlites at
Grib and Lomonosova in the Arkhangelsk region of neighbouring Russia.

The Company was formed in 2005 to continue the diamond exploration activities of
its parent, Tertiary Minerals plc. A pre-IPO fundraising was completed as an
entitlement issue to the shareholders of Tertiary Minerals and was followed with
a placing on AIM admission on 6 June 2005.

In 2004 Tertiary Minerals discovered two new kimberlites in the Kuusamo district
of northern Finland in what is now known as the Kuusamo kimberlite cluster.

Since admission to AIM on 6 June the Company has progressed quickly in its
evaluation of its untested targets at Kuusamo and, to-date, two new kimberlite
discoveries have been made one of which is now known to be diamondiferous.

The Company intends to progressively test priority targets defined by a
combination of magnetic anomalies and kimberlite indicator minerals. Indicator
mineral sampling and picking is continuing.

The Company continues to work closely with the diamond experts at the Geological
Survey of Finland (GTK), its main consultant and contractor and gratefully
acknowledges their contribution to the success of the programmes to date.
