Jimsy, perhaps a further discussion is in order here -- Boulay states: [essay is here: Message 8264960 ] >>Last year we [Marum] defined some systems in the Chinchaga that were under only one to four metres of soil or overburden..<< --NOT under deep overburden at all. The sprawling deposits are near surface and economically superior. More from the essay, as to deposits: >>..the bedded deposits referred to in the recent Ashton release are almost certainly pyroclastics, i.e. "hot grainy rocks", which were dumped at or near their current location after being blown out of the vent. They certainly may have been re-sorted a bit by water action but they are essentially in the same place they were a few minutes or hours after they were blown out and fell back to the sea floor... The tonnage potential of these bedded deposits in a place like Alberta are orders of magnitude higher than for pipe deposits and their geometry is amenable to "Alberta-style" mining, that is, gigantic scale mining operations using draglines.<< Also, >>Expect to hear a lot more about massive "bedded" kimberlite deposits and huge stacks of pyroclastic kimberlite slabs along with their production centres, the relatively small kimberlite pipes with diameters of only one kilometre or less.<< --relatively SMALL at one km or less?? - Imagine the sizes involved here... >>A 10 metre thick pyroclastic layer will contain roughly 30 tonnes per square metre or 30 million tonnes per square km.<< --Again, the potential for one township sized deposits was mentioned-- a township is roughly 9.5km square. ---- Lastly, from the essay, just to keep Marum's current objectives clear, >>For a while, the location of pyroclastic production pipes will be important as ore guides to the big layered deposits. In fact, our current exploration programs are focused on locating pipe vents (aka "kimberlite pipes").<< -- The pursuit of pipes is twofold: >>The vertical pipes are very important both as deposits in their own right and, very likely, as ore guides to much larger layered or "bedded" deposits.<< _______________ Best regards Jimsy, and please relate back to us from the PDAC! Sincerely, -j :> PS, this is the way I read the essay anyway! ;)
