Sonora Project in Mexico
"Having a shareholder register which already includes a number of blue chip institutions as well as a strategic partner in the form of leading Japanese trading house Hanwa will be invaluable, as the feasibility study at the Sonora Project in Mexico nears completion and we move closer to the construction phase of what we believe will be a world class lithium operation.
"The company remains on course with our objective to become a supplier of battery grade lithium carbonate to fast growing industries such as electric vehicles and energy storage, and I look forward to providing further updates on our progress in the months ahead."
Secker thanked Cadence for its contribution to the firm's development and that he looked forward to continue working with them.
Broker Shore Capital highlighted that last month Bacanora said it was expecting to complete the fully-funded Feasibility Study (FS) on its flagship Sonora lithium project in Mexico by the end of 2017.
It is targeting first production in 2019-2020, following an 18 month build programme and preliminary discussions have also begun with other debt providers for “more traditional” project financing packages, it added.
