Storuman Mine Permit Update

Tertiary Minerals plc, the AIM traded company building a strategic position in the fluorspar sector, is pleased to provide an update on the progress of the Mine Permit appeal process for its Storuman fluorspar project in Sweden.

Subsequent to the detailed update provided by the Company on the 13 December in the Annual Report, the Company has now been informed by the Swedish Government that the case has been referred to the Swedish Mining Inspectorate for re-assessment taking the new case law of the Norra Karr Mine Permit (rare earth element project owned by Leading Edge Minerals) into account. The re-assessment will now include the impact that mining activity may have on its surroundings (the "wider area").

Taking into account the new case law, the Company believes that the re-assessment is the preferred route for the case at this stage in the process and that the Environmental Impact Assessment ("EIA") prepared by Tertiary, and selected Swedish consultants, provides a sufficient description of the expected environmental impact on the wider area based on the extensive and detailed baseline environmental studies and reindeer husbandry impact analysis completed by the Company.

Once the case file has been received by the Swedish Mining Inspectorate the Company will continue to co-ordinate closely with them and will update the market accordingly as and when significant news is available.

Commenting today, Managing Director, Richard Clemmey said: "We are pleased to see progress is being made and are confident that the quality and extent of our EIA coupled with the expected continued support from key stakeholders in the project will provide support for a positive outcome for Tertiary in this process".
