If AUMY was doing nothing I would expect there loses to be small too. But, if Aumy is moving forward there will be capital investment in research, drilling, etc...The loses could be the proof they are doing something. It would be counted as a loss on the books until profits were realized from their, hopefully, positive results. A company will always rack up losses in the beginning before it turns.
At least that's an optimistic view of why their loses have increased. I'm willing to accept I could be totally wrong. Here's hoping I am right.
