The short numbers on shortman only show what is opened(Short sold).
Eg. Trader ABC borrowed 20%. Sold 18% as shorts, at the same time bought back 10%. He still hold 12% but sold a total of 8%.
On shortman, it show 18% short open.
At any moment he only need to buy back 8%
He can use his 12% to continue selling or give back (close). Lets say he close 5% from his 12%. The shortman would drop to 13%. He still has 8% to buy back on market.
If he was to close all 12%. Shortman would show there is 8% outstanding and he has to buy the 8% on market. The SP is to scare retailers senseless nothing to do with the company's performance.
Hope that helps explain.

MtC produce spod tied to spod price contract.

SDV will produce carbonate tied to carbonate price contract.

SDV will produce less in terms of LCE than mtC but three times the margin.
