The Maiden Resource is a key component of the current scoping study, which is on track to be published during Q2 2022 (the “Trelavour Scoping Study”). Key features of the study include:
Study to be based on producing battery grade lithium hydroxide utilising Lepidico’s L-Max® / LOH-Max® low carbon processing technology, a patented hydrometallurgical process to extract Li and other Li by-products
The Lepidico process is a low-energy, ambient condition leach using conventional industrial equipment and without the production of sodium sulphate
Lepidico’s case studies have demonstrated lower capital and operating costs for the technology compared to other known processing routes
Cornish Lithium has an exclusive licence in place with Lepidico which covers the entire St Austell granite region
Bench scale testwork has demonstrated that the Lepidico technology is applicable to mineralisation found at the Trelavour Project
Proximity to existing infrastructure is expected to reduce project capital costs
The Resource contains higher-grade zones, some of which are at surface and are expected to provide optionality for mining
Significant levels of high value co-products:
51.7 Mt at 0.11 % rubidium (“Rb”), 3.93% potassium (“K”) and 66.1 g/t caesium (“Cs”) resulting in contained metals of 56,870 t Rb, 2.0 Mt K and 3,417 t Cs as potential by-products
The Resource extends from surface, meaning a very low strip ratio, down to a maximum depth of 140 metres (“m”)
Estimated using drilling data from Cornish Lithium’s Trelavour drilling programme, which was completed in June 2021 and comprised a total of 30 drill holes totalling 4,358m
Jeremy Wrathall, Founder and CEO of Cornish Lithium, said: “We are delighted to announce this significant project milestone of Trelavour’s Maiden Resource. This is the culmination of a significant amount of work from the project team and will be a key element of the Trelavour Scoping Study, which we expect to publish during Q2 2022.
“We are excited about the potential of the Trelavour Project, which we are looking to develop utilising Lepidico’s low energy and low carbon footprint processing technology. This project is also expected to make use of the existing infrastructure in close proximity to it, which will both reduce the cost of development together with further reducing the project’s carbon footprint and minimising other environmental impacts.”
