                         PLAN TO DRILL PRIME IRON TARGET
                  IN HEART OF FINLAND'S MAIN IRON ORE DISTRICT

   • Testing Strongest Magnetic Anomaly in Kolari Iron District

   • Historic Work Points To Over 200 Million Tonnes Of Magnetite

   • Joint Venture Offer Turned Down From Leading Company In Order To
     Value-Add

   • Emphasis On New Nordic Projects Whilst Saudi Licence Awaited

Tertiary Minerals plc ('Tertiary' or 'the Company') is pleased to announce that
it intends to drill a prime iron ore target in Kolari at the heart of Finland's
main iron ore district.

The 'Sivakkalehto' target represents the strongest known magnetic anomaly in the
Kolari iron district where magnetite iron ore was last worked in the 1980's by
Finnish company Rautaruukki Oy. The Geological Survey of Finland (GTK) has
reported that geophysical interpretation of this magnetic anomaly suggests that
the Sivakkalehto deposit may contain over 200 million tonnes1 of the iron
mineral magnetite within a 2km by 300-500m broad area within Tertiary's claims.

The Sivakkalehto target sits in the heart of the Kolari-Pajala iron province
which stretches over the border into Sweden. Today, Canadian company Northland
Resources, capitalised at over £210 million, is undertaking intensive
exploration and feasibility studies on surrounding claims for the development of
a new iron ore mine. Last month Northland released a NI43-101 compliant2
iron-copper-gold resource at its 100% owned Hannukainen deposit at Kolari which
lies 10km to the north of Tertiary's Sivakkalehto target. Total Measured plus
Indicated resources are reported by Northland to be 84.6 million tonnes with an
average grade of 34.6% Fe, 0.20% Cu, and 0.093 g/t Au using a cut-off of 15% Fe.
An additional 81.6 million tonnes @ 35.7 % Fe + 0.13%Cu + 0.036 g/t Au have been
defined in the inferred category.

Northland's Hannukainen iron deposits give rise to distinctive magnetic
anomalies, but the Sivakkalehto magnetic anomaly is the strongest known in the
whole Kolari iron district and previous drilling by Rautaruukki Oy has returned
significant intersections of iron mineralisation which warrant follow up,
including:

Hole No.           From         To           Interval          Fe %
R1                  36m         347m         311m              14% Fe
inc                298m         303m           5m              62% Fe

R4                 203m         219m          16m              54% Fe

R21                239m         355m         116m              26% Fe
inc.               259m         304m          45m              40% Fe

R22                278m         296m          17m              56% Fe

R12                273m         304m          31m              56% Fe

Copper mineralisation has not been evaluated at Sivakkalehto although it is
known from limited historic assays to be present in places at low grades.

'The historic drilling results for iron compare favourably to those reported at
Hannukainen by Northland and suggests at least a similar resource potential
within our project, but this can only be confirmed by drilling.' commented
Patrick Cheetham, Tertiary's Chairman. 'There is a big economic advantage to
have production within the European market with significant savings on the cost
of importing iron ore from the southern hemisphere.' he added.

The Company has been approached in recent months by a leading company for a
farm-in at Sivakkalehto but has opted in favour of adding value itself before
talking to interested parties. It has just completed modelling of recently
collected airborne magnetic data, and is planning a drilling programme in
October to test for shallow iron-ore positions.

Tertiary is placing more emphasis on its Nordic portfolio, with new prospects
being generated, while awaiting the granting of its exploration licence on the
giant Ghurayyah tantalum-niobium, deposit in Saudi Arabia.

'Our activities in the Nordic countries have been on the backburner and
consequently overlooked by the market in recent times. We hope to be able to
give details of additional developments there soon.' commented Mr. Cheetham.

The Company has held its Kolari property for five years as part of its IOCG
(iron oxide-copper-gold) project portfolio. Other Tertiary IOCG deposits are at
Vahajoki, Finland and Ahmavuoma in North Sweden.
