Geology Question?

posted on Dec 13, 2007 06:23AM

Can anyone explain in practical terms what this geogist is saying?

- Geological Consultant Jim Mungall, Ph.D. Associate Professor from University of Toronto, visited project area in November, states: "If the less than peridotite greater than intrusion is accepted to be a conduit less than from a large intrusion greater than then it must be continuous over considerable distances likely measurable in kilometers. Since diamond drilling has shown that it is surrounded on all sides by older felsic intrusive rocks at surface, logic dictates that it must continue at depth."

Site Visit by James Mungall (Ph.D.)

During early November, the core from the Eagle One occurrence (up to hole 22) was reviewed by Dr. James Mungall, P.Geo., an Associate Professor in the Geology Department at the University of Toronto, specializing in Magmatic Massive Sulphides. Dr. Mungall completed a site visit report dated November 19, 2007 that includes the following summary and conclusion (taken verbatim from his report):

"The large amounts of sulfide and of ultramafic cumulate make it absolutely clear that the Eagle One deposit has formed in a magmatic conduit. No magma could have carried the observed amount of sulfide in solution, therefore the sulfides have been left behind by a through-going volume of magma much greater than what presently remains in the intrusion."

Dr. Mungall goes on to state "If the intrusion is accepted to be a conduit then it must be continuous over considerable distances likely measurable in kilometers. Since diamond drilling has shown that it is surrounded on all sides by older felsic intrusive rocks at surface, logic dictates that it must continue at depth. The prospects for continued extension of the mineralized body to depth are excellent, as long as it is not lost in a fault zone&. Although the rapid deepening of the conduit is somewhat discouraging, the presence of a weak magnetic feature south of the Eagle One deposit, that connects to the much more prominent magnetic feature to the south, may indicate that the plunge shallows at depth."

In conclusion and with reference to scope of the project he continues with "The origins of the sulfides are slightly problematic. It is generally accepted that in order to form a mass of immiscible sulfide liquid on the scale observed at Eagle One, a mafic or ultramafic magma must become contaminated by sulfide-rich crustal rock. At its present level of exposure the mineralized intrusion is entirely surrounded by sulfur-poor felsic intrusive rocks, leaving the origin of the required sulfide in doubt. I suggest that the presence of abundant magnetite-rich xenoliths in the intrusion records a previous episode of assimilation of iron formation, which has added sufficient sulfide to the magma to induce sulfide liquid saturation. The conduit has carried the slurry of sulfide droplets and small xenoliths to their current location, requiring transport over considerable distances. This in turn suggests that the Eagle One deposit resides within a large magmatic system with lateral extents at least as great as the distance to the nearest iron formation, which may be represented by the very prominent magnetic lineament to the south of the deposit."
