Jul 06, 2012 (P Sangster) - The northern nepheline syenite body, known as the Rutter Nepheline deposit, is exposed over an area of approximately 5000 by 500 m. It outcrops in a series of low glaciated ridges in low swampy terrain. The rock is coarse-grained, gneissic to massive and contains numerous small pegmatite segregations. In composition, it is approximately 40% white albite, 30% dark pink nepheline, 20% light pink microcline and less than 10% hornblende. Minor zircon, magnetite and aegirine were also noted.
Feb 03, 2009 (A Wilson) - The nepheline syenite is foliated and there is a considerable variation in relative proportions of of nepheline, plagioclase and mafic minerals from band to band.. The syenite is a meium-grained gnaitoid to granoblastic rock composed of white plagioclase, pink nepheline and microcline with hastingsite as the chief mafic mineral.

Feb 03, 2009 (A Wilson) - A grab sample collected by the OGS in 1959 returned: 28.4% nepheline, 42.6% plagioclase, 20.6% microcline and 8.2% hastingsite. A second sample returned: 21.8% nepheline, 41.9% plagioclase, 21.8% microcline, 7.0% perthite, 2.4% hastingsite, 1.3% aegerine augite and 3.8% opaques. Samples collected from Lot 11 concession 5 returned up to 48.9% nepheline. The syenite body extends for a distance of approximately 8 km in a north-south orientation.
