Gold breaks through $323, page-3

Fallguy, something that has occupied my mind of late which perhaps someone on HC might be able to answer. Take a company like OXR or RBK. Both are Australian companies yet their mining operations are off shore. Does this mean that their expenses are in the currency of the country of mining? If so these companies might do quite well if their currencies did not fluctuate as much as the $AUD.

Does anyone have an answer to this?
