SWK undertake mining (surface, underground diamond, production) for clients. They don't (at present) sell drilling equipment.
Gold mining clients are largest single sector, approx 40% of revenue from memory. Down from around 60% a couple of years ago as they have done some wise diversification.
SWK have publically stated that gold price is 'the biggest lever' on their utilisation (i.e. higher gold price = more drilling demand = more SWK rigs in use).
Hope this helps. I am not that familiar with pure mining stocks themselves, so can't help with respect to outlook etc for gold.
