In two places, stripping has shown that the south west ends of low lying ridges are composed of, medium grained titaniferous magnetite. These two occurrences lie close to the base line at 3N and 9N. At the latter locality the exposure measures about 150 feet by 170 feet. An outcrop of titaniferous magnetite was un-covered close to the base line some 15 feet east of an exposure of brecciated anorthosite. Other trenches and test pits were attempted in the area which only obtained bedrock in two locations near 18N 4 250tE and 15N + 500'E. In both cases, ore was encountered.

The deposits appear to lie along a major N.M. trending structure as indicated by a preliminary dip needle survey and brecciation in the surrounding anorthosite. A zone, one mile long and up to 1000 feet wide, has been roughly suggested within which dip needle readings are erratic and no outcrop of anorthosite has been found.

Description of the Ore

The titaniferous magnetite is a glistening black mineral on fresh surface weathering to 'polished shoe' black. In hand specimen obtained from the surface, the break is characteristically a rusty yellow colour, an occasional small crystal of a green mineral can be seen. The mineralization is often quite granular in appearance exhibiting well developed crystals. No apatite or sulphides were seen in any of the specimens examined.
Results of analyses carried out by the Quebec Department of Natural Resources on chip samples taken from three of the main exposures are tabulated as follows:

Sample	Fe %	TiO2 %	SiO2 %	Al2O3%	MgO%	CaO %	P2O5%	S %	V2)5%
BM 30	51.14	19.51	0.61	6.38	3.44	0.14	0.01	0.002	0.65
BM 31	51.14	19.19	0.57	6.72	3.20	0.14	0.01	0.012	0.64

A Davis tube magnetic separation test of a composite sample powered to minus 200 mesh gave the following results.

	West Percentage	Fe %	TiO2
Magnetic Portion	77.8%	57.46%	15.94%
Non Magnetic Portion	22.1%	27.15%	32.06%

This information combined with an examination of a polished section under high magnification by Mr. J. P. Giraud of the Quebec Department of Natural Resources indicates that the ore is an Ulvo Spinal with a certain amount of intergrown ilmenite and very similar to La Blache mineralization.
