RE:The negatives & some questions
I'm not quite sure what options you mean. There are shares that will be free for trade at Nov. 21st (12.5M bought at $1) and Nov. 26th (around 1.7M bought at $1.17) from the financing in July. This financing is completed, and brought the company $14.5M.
These shareholders also holds warrants (0.5 for each share) exercisable at $1.50 and $1.75. So outstanding warrants are:
13,919,138 exercisable at $0.50, expiring Nov. 20, 2017
7,078,255** exercisable at $1.50 expiring July 20, 2017
1,829,061 exercisable at $1.75 expiring July 25, 2017
(from newest company presentation: https://www.k92mining.com/wp-content/uploads/2016/11/K92-Mining-Presentation-November-2016.pdf)
There are also around 7.3M outstanding options. AFAIK they're in the hands of the management (Slusarchuk, Angus, Stalker and Lewins owns more than half of them).
Current working capital is $14.5M. Maybe the cash flow from Irumafimpa will be enough to finance development and exploration going forward, but I really have no idea.
As for the Papua tax rate, the company presentation says "Competitive tax and regulatory environment". But I'm guessing you're looking for a somewhat more precise answer ;-)
