Lucky Project Drilling

Tertiary Minerals plc is pleased to advise that drilling is scheduled to start today on the Company's Lucky Copper Project in Nevada, USA.

The target is a disseminated sediment hosted, intrusion-related copper deposit and details of the project and the planned drill hole can be found in the Company's announcements of 29 May 2020 and 11 January 2021.

Results of the drilling will be advised once analytical results become available.

Commenting today, Executive Chairman Patrick Cheetham said:

"We have decided to drill at an early stage on this project as historical exploration results present an immediate target with reported copper mineralisation that needs to be confirmed and put into a better geological context.   We look forward to reporting results as they become available."
