              TERTIARY STARTS DRILLING AT ITS MAIN NICKEL PROJECT
                             AT NOTTRASK IN SWEDEN

   • Central Zone Highlighted By World Expert On Nickel Sulphide
     Mineralisation
   • Multiple Massive Sulphide Targets Confirmed By Detailed Ground
     Geophysics
   • Five Diamond Drill-Holes Planned As Initial Test Of Priority Anomalies

Tertiary Minerals plc, ('Tertiary' or 'the Company') announces drilling that has
started at Nottrask, the Company's main nickel prospect in Sweden. The programme
will test multiple targets for nickel-copper massive sulphides identified by
geophysical surveys.

On April 13 the Company announced results from a large loop semi-regional
transient electromagnetic (TEM) survey across the Central Zone of the Nottrask
mafic intrusive that identified a total of nine, closely spaced, near-surface
conductors and one deeper conductor, interpreted to indicate massive-sulphide
mineralisation. Drill testing was put on hold awaiting the Spring thaw.

A detailed follow-up Slingram electromagnetic survey has just been completed and
confirms conductors with individual thickness up to 60m, possibly comprising
multiple stacked massive sulphide lenses. The drill targets are on three
distinct horizons within a strike length of 750m.

Drilling of up to five holes is planned as an initial test of the conductors and
is scheduled for completion in July with assay results following a month later.
Tertiary and its consultant Anthony Naldrett (Emeritus Professor at University
of Toronto and an internationally acknowledged authority on nickel sulphide
mineralisation) highlighted the Central Zone of the Nottrask mafic intrusion as
having the potential to host commercial-grade nickel-copper sulphide
mineralisation.

The Nottrask intrusion is interpreted as being in the north-western extension of
Finland's Kotalahti Nickel Belt which hosts numerous nickel mines, including
Outokumpu's Hitura and Kotalahti mines.

'The geophysical anomalies, whilst still speculative for nickel-copper, are
'text-book' examples for massive sulphides and along strike from a major nickel
sulphide mining belt. A new nickel discovery in this established nickel-mining
region would be particularly exciting.' commented Patrick Cheetham, Tertiary's
chairman today.
