The last estimate for the CHPP was $14.7 mil USD ( Aug 2017) but by the looks of the co Ann Feb 2018  the CHPP wont be needed for at least 2 years. For this reason the capital requirements above and beyond normal production costs for the calendar year 2019 are uncertain .

Perhaps the strategy now is to wait until 2019's financial results before seeking the major loan to upgrade to phase two 1 mil t/p/a.

The last comprehensive estimate for upgrading to 1 mil t/p/a was in Aug 2017 for a total of $98.8 mil USD . This included capital costs 

for 2017 to 2019 but with the deferment of production ramp up , it is now difficult to forecast both the timing and borrowings  required.

Since the. Aug 2017 ann over $10 mil has been spent on plant-equipment and construction with an unknown amount for these items 

 in the current calendar year. 

I guess we'll have to wait for an update
