Drill holes spaced every 50 to 100 meters. Findings extended proven zone by 275M in linear ground distance; i.e. for arguments sake, if you described the top of the B-Zone find as the rectangular area you might cut as an open-pit, we just extended the rectangle by 275M in length (along strike). Basically they're saying the TREO bearing pegmitite spine has been proven to extend another 275M disappearing under the lake.
