Magma is molten or partially molten rock beneath the Earth's surface. When magma erupts onto the surface, it is called lava. Magma typically consists of (1) a liquid portion (often referred to as the melt); (2) a solid portion made of minerals that crystallized directly from the melt; (3) solid rocks incorporated into the magma from along the conduit or reservoir, called xenoliths or inclusions; and (4) dissolved gases.

Abstract

Key factors for the formation of world-class magmatic Ni-Cu deposits include sulfide saturation in magma, large magma/sulfide ratio and accumulation of sufficient quantity of immiscible sulfide liquid in limited localities. Results from two well-known Ni-Cu deposits in the world, the Talnakh deposits in Siberia, Russia and the Voisey’s Bay Deposit in Labrador, Canada, indicate that a dynamic magma conduit in the upper crust is an ideal environment in which these factors can prevail.

===========================

This is from the the NOT web sight:

Geological consultant Jim Mungall, Ph.D, Associate Professor from the University of Toronto, visited the Double Eagle project in November. "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. If the intrusion is accepted to be a conduit then it must be continuous over considerable distances likely measurable in kilometres."

3) Noront management feels that the drill results obtained to date at Eagle Two are consistent with the conceptual model it has developed to date, which would suggest that there is potential for the discovery of another Eagle One - type deposit, as the Eagle Two mineralization is traced northwestward into a possible feeder conduit. The potential for both Chromite and Ni-Cu deposits within the Ring of Fire Intrusion ("RFI") itself remains virtually untested.

- A mantle derived, highly magnetic ultramafic "peridotite" intrusion ("the Ring of Fire Intrusion" or "RFI") has been emplaced along the margin of a regional scale granodiorite pluton which had been intruded into and caused a doming of the host Sachigo greenstone belt rocks. The RFI is thus situated between the granodiorite on one hand (footwall) and the surrounding Sachigo Greenstone Belt rocks (hangingwall) on the other. The RFI is magnetically distinct allowing it to be traced more or less uninterrupted, for tens of kilometers along the granodiorite margin. It appears that a series of conduits cutting across and through the granodiorite have acted as feeders to the RFI.

- Recent drilling within the Ring of Fire area confirms that both PGM-rich Ni-Cu deposits (Eagle One and possibly Eagle Two) and now chromite occurrences are associated with the RFI and its related conduit feeder system. As would be expected under the conceptual model, on-going drilling by Noront and published results from other junior companies working in the area, suggest that the layered chromite mineralization is likely to be confined strictly to the RFI, while the platinum rich Ni-Cu sulphide mineralization appears, at least at this stage of exploration, to be related to the conduit feeders, localized in pools or traps. Based on observations from similar intrusives globally there is no reason, at least conceptually, why Ni-Cu or PGM deposits could not be hosted by the RFI itself. The exploration potential in this regard remains to be tested.

more from press release

- Using the conceptual model, the Eagle One deposit would be interpreted to occur within a conduit feeder, at some distance from the RFI. The Eagle Two discovery on the other hand is interpreted under the conceptual model as occurring within the "throat or mouth" portion of the conduit where it empties into the RFI. The mineralization yielded by Noront's results at this point in the system consists of mineralized zones that contain numerous thin (10 cm to 120 cm) Ni-Cu bearing sulphide layers occupying a shear zone that collectively amass to 10's of meters thick "fingers" that "feather" out into the RFI. Individual semi-massive to massive sulphide lenses within the SHS zone attain core lengths of up to 7 meters.

I'm sure the geo's here will correct any inaccurate connections here but it helps to have a picture and other frames of reference.
