To begin with I am not a geologist. Also, I am repeating this info to the best of my ability and a rough set of notes.
HM was right when he commented on the confusion of some terms.
The Rice Lake Mine is located just off the 1st hinge axis.
The Hinge zone is located just off the 3rd axis pathway.
The axis are about 500 meters apart.
For the following see page 20 of Dale's Zurich presentation.
Hinge #4 is the main vein in the "newly discovered" Hinge zone and is the main find. That is why the Hinge zone and Hinge #4 are used interchageably. Hinge #3 and Hinge #1 are additional veins in the Hinge zone. They are not newly discovered areas but additions to the initial hinge zone.
Drilling has been done on a completely new area and those results are pending.
There are no results out for any other area than the hinge zone.
