While the primary source is the ultimate goal, I think the best approach is to test underneath the main intersection first in gradual step-outs (50-100m). This will build up the picture of the plunge of the system and reduce the risk of missing the target altogether. Down hole EM should be done in conjunction to this. I would be surprised if they haven't already done this in RC5, but they don't need to release the results if they have come back negative (good chance of this in the oxide zone). All it takes is for a decent off-hole anomaly and you straight away have your target. Geochemistry is important and can vector you in, but no where near the power of DHEM as a direct targeting tool.

The gradual approach will keep the interest levels high assuming similar assay results to RC5. Jumping straight in an doing a deep hole is a very risky approach and very costly. They didn't have much success at Forrest with this approach. One dud hole won't be a good look.
