MB Fluorspar Project - Update

Tertiary Minerals plc, the AIM traded company building a strategic position in the fluorspar sector, is pleased to advise that:

·; The proposed drilling programme for the MB fluorspar project in Nevada is now permitted

·; The contract for the drilling programme has been awarded and will start by mid-July

The programme has been approved under a Notice to conduct exploration drilling by the US Bureau of Land Management (BLM) and a Reclamation Bond in the amount of US$18,841 has been lodged and accepted by the BLM.

The drilling contract has been awarded to Boart Longyear following a competitive tender process. Boart Longyear is the world's leading provider of drilling services with 120 years in the business.

Details of the proposed drilling programme were set out in the Company's announcement of 9 May 2013. Phase 1 of the drilling programme will evaluate the most cost-effective drilling technique for the MB Project and drilling is expected to be completed by the end of July, with analytical results expected by late August.

Phase 2 of the drilling programme aims to define an initial 1JORC compliant Mineral Resource and to indicate the extent of higher grade areas in the centre of the known deposit. This phase will commence when results from Phase 1 are known and the duration of the drilling campaign will depend on the drilling method. Further information will be provided on the completion of Phase 1.

Commenting today, Operations Director, Richard Clemmey said: "We are delighted that we now have the necessary approvals to start our drilling on the MB Project."
