$10m, $20m is nothing for BHP. If you think APG was/is the only company they put money into you are very wrong. They have many of these investments. Obviously they realised it was not going to be able to deliver what they initially thought and quickly ceased supporting it.  If it could, they would have bought it out and and applied the necessary finishing adjustments. it’s how BHP works. 

I remember first dealing with MT back in 1998. Lovely guy. They had been developing the tech for 10 years up until that point and believes they were almost there. Stocks was trading around 14c from memory. BT had a 54c price target. Ticor were involved. 20 years later, and some chopping and changing in development and here we are on the brink of collapse with a technology which looks as though is either 1. Ineffective, 2. Unnecessary, or 3. Not commercially viable.

that is why they are asking you for money at $0.001.
if it was solely MT (management), that would be easily solved by buying the company for some loose change and taking control.

keep your eyes on Gumtree, you never know what you may be able to find in 2019
