Point Location Description: Pegmatite dyke in outcrop on east shore of Nemegosenda Lake.
Location Method: Data Compilation
Access Description: Access is rather difficult. It is possible to portage a canoe down the Nemegosenda River but the portage into the lake is a kilometre long. The closest access with a wheeled vehicle is to a point on Highway 101 and then a 3 kilometre traverse is required. The easiest access is via float plane from Chapleau or Foleyet.
No exploration has been carried out on this prospect.
Province: Kapuskasing Structural Zone
Geological Age: Mesoproterozoic Geochronological Age: 1015 +/- 63 MA Geochron. Age Ref.: OGS STUDY 34, P. 29
Dec 07, 2005 (A Wilson) - The Nemegosenda Lake alkalic rock complex consists of fine-to medium-grained syenitic to malingitic rocks which are bordered along the south by a mass of coarse-grained nepheline syenite. The rocks are cut by a series of lamprophyre, porphyritic syenite and rust brown-weathering carbonate dikes. The complex is enclosed by the gneissic rocks of the Kapuskasing Structural Zone.

Dec 07, 2005 (S Fumerton) - The mineralization is hosted in a 1.2m thick orthoclase - aegirine pegmatite which has been emplaced in the Kapuskasing gneisses.
Dec 07, 2005 (A Wilson) - The mineralization is reportedly hosted in a 1.2 m wide orthoclase-aegirine pegmatite which has been emplaced in the Kapuskasing gneiss. Visible pyrochlore has been identified in the pegmatite.
