Talking about cash position, RVX will get help from its sister company Zenith...

Zenith received money from its milestone payment.

It will now be able to repay its 1M+ debt to RVX.

Maybe RVX could ask for an advance too.

Worst case, DM could stake the company as he did before the Third Eye loan and as he did Zenith before their reception of Newsoara money:

During the three months ended July 31, 2019, a relative of the Chairman of the Company lent CAD$0.5 million to the Company. This promissory note is payable on demand and bears interest at 8% per annum. Subsequent to July 31, 2019, this promissory note was repaid.

During the three months ended July 31, 2019, the Chairman of the Company and another director of the Company lent CAD$0.3 million and CAD$0.1 million, respectively, to the Company. These promissory notes are payable on demand and bear interest at 5% per annum. Subsequent to July 31, 2019, the promissory note payable to the Chairman of the Company was repaid.

TL;DR I think RVX can survive for a few months, clearly until AHA with their cash reserves.
