From past announcement:
"Jiangxi Baojiang Lithium Ltd., a joint venture between Jiangte and trading firm Burwill Commodity Ltd., is currently building a factory to produce 10,000 tons of lithium carbonate and 5,000 tons of lithium hydroxide a year, and the plant which will rely on supplies from Bald Hill."
i have read a few posts stating 7-8 tonnes of 6% spodumene to produce lithium carbonate and hydroxide.
Therefore, let's assume 15kt x 7.5 = 112kt @ 6%.
Given our annual ouput is already meant to exceed this amount (without fines), it seems logical we need another offtake customer.
