With pressure from the originating magma chamber, surrounding rock will be pusted open causing weakness (cracks) through which magma can channel. When it encounters the granite (course grained/irratic cleavage as well as melting) the weakend (stressed) rock can crack open in a myriad of patterns. Thus allowing leakage and seepage into surrounding rock as well as movement in irratic manner as it creates a channel forward. Thus, near misses can tell a lot about where the nearby mineralization actually is.
So long as the magma is in solid rock its path can take varia twists and turns. When it breaks to the surfice it becomes a lava flow which will fill low ground and surrounding fissures (ie. Voisy's Bay Extentions?).
Given that this area (James Bay Lowlands) experienced several periods of Glacial Erosion it is likely that what has been discovered occured deep in the crust within a Granite rock formation. Thus the magma path is likely very irregular, with large and small accumulations of mineralization all along its path. Without evidence of pre-existing faulting in the vacinity, the deposit can have a very irregular shape, and thus its dimentions rather difficult to determine and consequently the resource also difficult to quantify.
Just, perhapse, part of the challenge NOT has to deal with.
As a sidebar: It will be interesting if, as drilling continues, different rock composition becomes associated with the area surrounding the mineralization zone.
#8 is a one liner found on the Sept. 27 NR. It is to undercut #7 from Location #1,2,7. The dip is not specified.
PS: Those of you with bells and whistles at hand, good for you. Don't forget the guy's with bells, whistles, horns, and, yes, even pipes are very likely already getting in on the play. So, enjoy all.
