Ann: Quarterly Activities and Cash Flow Reports - 31 Dec 2022, page-22

They gave the figure for cash at the end of Dec on the 4C at 13.8M and then another figure at the end of jan 10.2 M seems like burn had dropped down in the last month to 3.6 M against a burn for the quarter of 13.8 M (so 4.6M a month ) indicating the cash burn has decreased in the last month.
therefore they have a runway of arond 3 months before cash runs out rather than as you suggest they will be finished by end of Feb .
