Confusion due to words.

I understand that the convergence zone is the expected ore body below Eagle's Nest . Hole 49 accidentally discovered the richness of Eagle's Nest, while the convergence zone ( otherwise referred to as 'up side down Elephant's body') is the expected continuation of Eagle to depth and eventually possibly sideways to other near by known and expected resources.

The deep drills are drilling to depth to prove up the continuation of the known resource to greater depths.

I happen to believe that the so called convergence occurs at very deep depths that are probably too deep for drilling and mining.
