I really think they should put in place some copper price hedges. The current Cu price is well off its highs, but its still a decent and profitable price. It would put some level of certainty into place.
If the Cu price falls from here, KZL would be in REAL REAL trouble. Whereas if the Cu price were to rise with the hedge in place, sure we'd miss some upside but KZL would still be alive and ready to capitalise as the hedges drop off.
