Storuman Project Mine Permit Update

Further to the operational update provided in the RNS dated 12 December 2018, Tertiary Minerals plc, the AIM traded company building a strategic position in the fluorspar sector, has today received news from its Swedish Lawyers regarding the Exploitation (Mine) Permit re-assessment for the Company's Storuman Fluorspar Project in Sweden, summary as follows:

· The Swedish Mining Inspectorate ("Mining Inspectorate") has chosen to agree with the County Administrative Board of Västerbotten ("CAB") assessment and it has rejected Tertiary's application

· This is despite the fact that the Mining Inspectorate simultaneously states in their decision that the economic aspects point in favour of granting the exploitation concession, that a permit regarding Natura 2000-area is unnecessary, that fluorspar is included in the EU list of critical materials and that a mining establishment would mean positive socio-economic benefit for the municipality of Storuman

· The Mining Inspectorate has however agreed with the CAB's assessment that the protective/mitigation measures suggested by Tertiary are not sufficient to enable coexistence between mining and reindeer husbandry

· The Company's Swedish lawyer has commented that the Mining Inspectorate has not fully assessed the case regarding the protective/mitigation measures suggested by Tertiary and has instead only taken the CAB's assessment into account. It has recommended that Tertiary appeal the decision to the Government

· Tertiary will now fully assess the decision and intends to lodge an appeal with the Swedish Government in line with the advice of it's Swedish lawyer

Commenting today, Managing Director, Richard Clemmey said: "We are disappointed that the Mining Inspectorate has taken this decision based on the application in its current form. We, together with our Swedish Lawyers, will appeal the decision to the Swedish Government and will now assess the future options available to the Company".
