CONTRACTΒ AWARDEDΒ FOR MINERAL PROCESSING TESTWORK ON STORUMAN FLUORSPAR PROJECT
Work Forms Major Component Of Economic And Technical Scoping Study

Storuman FluorsparΒ ProjectΒ Sweden
Tertiary Minerals plc ("Tertiary" or "the Company")Β is pleased to reportΒ thatΒ it has awarded a contract to
SGS LakefieldΒ (Canada)Β to complete an extensive programme of mineral processing testwork to evaluate
the production of acid grade fluorspar concentrates from the Company's Storuman fluorspar project. The
testwork is a major component of anΒ Economic and Technical Scoping StudyΒ to evaluateΒ development of
the project that is planned to be completed later this year.
The StorumanΒ mineral processingΒ testworkΒ will be based on a scope of work put together by the
Company's consultingΒ engineer, a specialist in Fluorspar flotation separation, andΒ will be undertaken on
samplesΒ collected from the Company's recent drill programme.Β The programme will take about 16 weeks
andΒ is scheduled to startΒ in about 6 weeks time.
The preparation of theΒ Economic and Technical Scoping Study will run in parallel with,Β and make use of
the results from,Β theΒ mineral processingΒ testwork. The contract for thisΒ studyΒ will be awarded shortly,Β and
is expected to be completed by the end of the year.
Meanwhile the price of fluorspar continues to climb on world markets,Β driven byΒ aΒ contractionΒ of supplies
fromΒ China. The latest price isΒ US$380-400/tonneΒ (dry-basis, deliveredΒ Gulf)Β and this is forecast to
increase further.
A previous mineΒ designΒ madeΒ for StorumanΒ by Granges International in the 1970sΒ captured some 1.7
million tonnes of fluorsparΒ in a combined open pit and underground mine based on resources delineated at
that time.Β The mineralisation is not yet closed off by the existing drilling and there is believed to be potential
for substantial extensions to the known mineralisation.
The receipt of assay results from recent drilling at Storuman,Β initiallyΒ expected by the end of June, will now
be delayed for a period of approximately 6 weeks following technical problems at the independent
analytical laboratoryΒ identified byΒ theΒ Company's rigorous quality control procedures. UseΒ of this laboratory
has been suspended andΒ a new set ofΒ samplesΒ have beenΒ sent to an alternative laboratoryΒ for analysis.
Kolari Iron Project
InΒ Finland, at the Kolari iron project, where the Company isΒ targeting a large depositΒ of disseminated
magnetite iron-ore,Β a number of samplesΒ have been submittedΒ Β for separation testworkΒ toΒ assess the
recovery and characteristics of the contained magnetite. The testwork is being conducted at SGS
Lakefield inΒ Cornwall.Β
TheΒ Kolari iron depositΒ sits at the heart of the Kolari iron provinceΒ where Northland Resources has recently
announcedΒ aΒ positiveΒ scoping study for development of a number of iron deposits in the area.
The iron ore marketΒ alsoΒ continues to strengthen. A 96% price rise was recently agreed between Rio Tinto
and ChineseΒ consumers for iron ore fromΒ its PilbaraΒ mines inΒ WesternΒ Australia.Β

BackgroundΒ -Β Storuman
Tertiary was awarded the Storuman exploration licence in January this year. The Storuman fluorite deposit is located in an area with well established infrastructure. It is located adjacent to a sealed highway 20km from the regional town ofΒ StorumanΒ which is connected by road and rail to the city andΒ portΒ ofΒ UmeΓ₯Β on theΒ Gulf of Bothnia. In the other direction the highway leads to theΒ port city ofΒ Mo-i-RanaΒ inΒ Norway.
Fluorspar is the commercial name for the industrial mineral fluorite (calcium fluoride - chemical formulaΒ CaF2). It is the main industrial source of fluorine for the manufacture of hydrofluoric acid and derivative fluorine chemicals including refrigerants, PTFE (Teflonβ’) and aluminium hydrofluoride, a flux used in the reduction of alumina to aluminium. It is also used as a flux in steel making, in the ceramics industry and in the manufacture of nuclear fuel (uranium hexafluoride).
Fluorspar consumers, several of which are based inΒ Europe, are facing critical supply shortages as traditional supplies fromΒ ChinaΒ are diverted to meet growing Chinese domestic demand.Β ChinaΒ has recently imposed export quotas and export taxes to discourage export and thus ensure domestic supplies.Β
A conceptual target for the Company is a mining operation producing at least 100,000 tonnes per annum of acid grade fluorspar.Β The world market for fluorspar is just over 5 million tonnes per annum of which 65% is for acid grade fluorspar.
BackgroundΒ - Kolari
InΒ Finland, at the Kolari iron project, three scout holes and the re-logging of a number of historic drill holes from the Sivakkalehto deposit have validated the potential for a substantial tonnage of near surface bulk-mineable iron mineralisation. Over the 550m strike length so far evaluated drilling has defined a coherent envelope of disseminated magnetite mineralisation over 100m wide with aΒ magnetite content of approximately 30% (equal to approximately 20% Fe). Most historical drill intersections were made in this body at depths of 100-300m but interpretation of ground magnetic surveys and the results from the Company's three shallow drill holes suggests that the body is sub-vertical and sub-crops beneath glacial till cover.
