Cornish Lithium Extends Exploration Option for a Further 12 Months

Under the Exploration and Option Deed (the "Deed") entered into by the Company and CLL in January 2017, CLL has chosen to extend the Deed for an additional 12-month period in consideration for the issuance to the Company of shares in the capital of CLL equal to US$100,000 based on CLL's last share issue price. Upon receipt of the shares, the Company will own 6,713,940 shares of CL.

Background

• Cornish Metals granted CLL an option to explore for minerals in brine and geothermal waters on Cornish Metals' mineral rights in Cornwall, UK, in January 2017 (see news release here).
• The Company will have a 25% free carried interest in CLL's first project on the Company's mineral rights which has a Bankable Feasibility Study completed on it. Following the Bankable Feasibility Study, the Company will be required to contribute its share of development costs or its interest will be diluted.
• The Company will have a 10% free carried interest in each subsequent project developed by CLL on the Company's mineral rights which has a Bankable Feasibility Study completed on it. Following the Bankable Feasibility Study, the Company will be required to contribute its share of development costs or its interest will be diluted.
• The Company will have a 2% Gross Revenue Royalty payable from any production by CLL of minerals from brines from the Company's mineral rights and a 2% Gross Revenue Royalty payable from any geothermal energy produced by CLL and sold to the National Grid or other system from its mineral rights.
• On each anniversary of the date of the Deed for the initial five year period, CLL had the option to extend the Deed for a further 12-month period in consideration of the issuance of US$50,000 in shares in the capital of CLL to the Company.
• Commencing January 2022 up to and including January 2026, in the event CLL elects to extend the Deed for a subsequent 12-month period, the annual payments to the Company will be US$100,000 in shares in the capital of CLL.
• CLL can continue to renew the Deed after January 2026 but with a rising option fee.
  

Richard Williams, CEO, stated "We welcome Cornish Lithium's decision to continue to explore our Mineral Rights for lithium in brine, a decision that reaffirms the exploration potential for lithium in a variety of geological environments in Cornwall. We look forward to working with CLL over the coming years to progress the development of the UK's first lithium in brine project."
