If you think in terms of a 3D object and look at the CROSS Section, then you can generalize it to SOMEWHAT resemble an Elliptic shape. The Cylindrical representation would correspond to the strike or trend. Thus the representation in generalizations. One important additional aspect to recall is that RN did also state that it appears to be widening as they drill it to depth. With this in mind, you may soon be able to think of it (the mineralization) as taking on a SOMEWHAT cone shape as well (where the apex of the cone is at surface and the aperture is getting larger with depth). With all this it is also important that its direction(s) at depth are only now being defined. Old Joe
