There is no floor or ceiling price. The contract with yahua is linked to Fastmarket contract pricing. It's written in plain English in the reports.
The company made $20.1m with DSO in December and will have around $21.32m(3500t) + $72.28m (91.6@80%) = $113.7m. This is the amount Cxo will have earned so far. Which part do you not understand. Yahua will take their first 15kt in July. It does not mean the company will only produce 15kt between now and July. They can produce more.
The mine began producing in November, in 1 month they produced 15kt of DSO and enough to process 3500t of spod from Feb to march, after the DMS was completed. Read the report, it's in plain English.
The company announced 12year minimum life, it has since increase by 62%, this equates to around 20 years. More deposits are still being discovered.
The company is spending more on exploration, this should read the company is doing more drilling based on fleet space information.
The banks predict $950/t yet contract pricing is between $4-$5k/ t. An obvious lie. Spot price represent around 5% of sales. It's a manipulation tool being used which many just don't understand. $950 is below MIN cost to produce at $1200. The industry would shut down and China/CATL would be broke, no supply for their batteries. Hundreds, even thousands are employed to troll sites like HC to manipulate the SP especially the chart thread. Wake up, read the reports.
