copper smashed massive pressure on pna, page-4

i asked this a couple of days ago and no response however two things im interested in are:
on what basis are the operating expenses paid for? are these in USD or in local laos currency or even AUD? just interested to see how the strengthening USD will impact results on the cost side?
also does anyone have any knowledge on the US80M short term debt? is there likely to be issues with the rollover of this?
think this correction will provide upside however like most people im keeping my hands in my pockets right now. been burnt catching a falling knife once too often recently (and the boss is getting narky about this too).
if anyone has some insight into the above it would be greatly appreciated
another thing, whens the quarterly due?
