Point Location Description: adit

Location Method: AMIS Site Visit

Access Description: Generally easy access to the area is possible via the Nemogesenda logging road. Northwest off this road near the intersection with the highway is a secondary road leading towards Nemogesenda Lake and some recent logging operations. The logging road leads towards the area of the old camp site and a short traverse is required to reach the adit. The Ministry of Natural Resources have attempted to barricade the road in a number of places and post signs stating that access to the area is prohibited.



Exploration History

1880: discovery of apatite in granite on shore of Nemegosenda Lake by GSC. 1954-56: Dominion Gulf flies regional magnetic survey; ground magnetic survey completed, mapping of area, drill program, bulk sample; DD-68-350306 ft. and resource calculation made; 1958: adit driven into D Zone, reserve calculations, 390 tonne bulk sample. 2008-11: Sarissa Resources Inc. - DD-12-2668 m, mineralogical study, ground geophysics

Geology

Province: Kapuskasing Structural Zone

Geological Age: Mesoproterozoic   Geochronological Age: 1015 +/- 63 MA   Geochron. Age Ref.: S 34, p. 29



Geology Comments

Nov 10, 2010 (S Fumerton) - The nepheline syenite pipe has a magmatic ring structure on the large scale where as on the small scale magmatic brecciation is important. The breccia at the deposit is located at the contact where the alkalic magma intrudes the altered country rocks.


Nov 10, 2010 (A Wilson) - The Nemegosenda Lake Alkaline Complex consists of fine- to medium-grained syenitic to malingitic rocks which are bordered along the southern rim by an arcuate mass of coarse-grained nepheline syentie. The complex is enclosed in a fenitized envelope produced by metasomatism. The complex is cut by numerous lamprophyre, porphyritic syenite and rusty brown-weathering carbonate dikes. The complex is enclosed within the gneisses of the Kapuskasing Structural Zone. There is much evidence of post-ore faulting in the area of Zone D mineralization. There are a series of NE trending faults that cut off Zone D to the west. Within the ore zone the most prevalent type of faulting is NW.

Lithology Comments

Dec 07, 2005 (S Fumerton) - A large intrusive nepheline syenite pipe referred to as the Nemegosenda Lake alkalic complex hosts the mineralization. This intrusive in turn is located and related to the Kapuskasing Structural High. The mineralized phase is a fine to medium grained malignite or melanocratic nepheline syenite. Accessory minerals include aegirine, biotite, garnet, pyrochlore, magnetite and apatite. This malignite has by a process of magmatic stoping intruded and altered the adjacent wall rocks forming fenites. Extensive descriptions of the geological setting have been published.


Dec 07, 2005 (A Wilson) - The mineralization is hosted at the contact between syenite and red alkaline fenite. The alteration of the fenite to feldspar has involved the extraction of pyroxene and pyrochlore forming ions.

Mineralization Comments

Dec 07, 2005 (S Fumerton) - The mineralization is associated with pyrochlore with the malignite and fenite. Pyrochlore occurs as zoned crystals as inclusions within or adjacent to aegirine augite grains. Though a number of commodities have been listed for this deposit, only the niobium content was evaluated.


Dec 07, 2005 (A Wilson) - Pyrochlore occurs as zoned crystals as inclusions with or adjacent to aegirene-augite grains.

Geologist: P Sangster

Notes: The property was inspected by M. Galsworthy (Ministry of Natural Resources Chapleau), L. Peesapati (Ministry of Labour, Timmins), L.E. Luhta (Resident Geologist) and P. Sangster (Resource Geologist) as a reported potential hazard. Mr. Peesapati will notify Dominion Gulf as to the remedial action. Subsequent to notice by MOL of necessary remedial work being sent to Dominion Gulf, we have been notified by Mr. L. Tihor of Chevron that the property is now owned by Chevron. Mr. Tihor will consult MNR on possible remedial action. MNR staff will sample core stored on site and add to Regional Core Library.
