Point Location Description: Mineral occurrence at surface symbol (Map, GDIF068)
Location Method: Conversion from MDI
Access Description: The showing is located west of Highway 69, Lot 9, Concession IV, Dill Township. The showing is accessible by driving 4 kilometers southeast of McFarlane Lake on Highway 69 to a trail running southwest. The 1.5 kilometer extent of this trail terminates at a small lake; the showing is located on the north shore of this body of water.
The showing was first reported by Lumbers (1975, p.141). No record of prospecting or development is available. DEPOSIT NAME: OCCURRENCE I REFERS TO GDIF 68 MAP 2.

Jun 09, 2009 (D Scholtz) - The migmatized biotite gneisses in this area are adjacent to the Grenville Province Boundary Fault and display a high level of metamorphism. Kyanite laths generally follow the contorted foliation of the melanocratic biotite gneiss, with tiny garnets occurring in localized pockets. Adjacent metamorphic gabbroic intrusions, younger than the gneisses, augment the structural and lithological complexity of this showing. Kyanite occurs in gneiss near the Grenville Front Boundary Fault. Kyanite is erratically distributed throughout the gneiss which contains up to 43% kyanite. (GDIF068) Kyanite is a high grade metamorphic alumina-rich mineral often found in close association with garnet. In the Sudbury District two such properties in close proximity to the Grenville Front Boundary Fault have received considerable geological and developmental attention. The milling and extraction of kyanite from the ore must be fully examined before a mining operation is initiated. The most promising of these properties is the Kyanite Corporation of Canada Limited's Crocan Lake kyanite deposit. The three bands of ore in Middle to Late Precambrian amphibolite schist straddle the Butler-Antoine Townships border. The presence or absence of garnets in these ore zones is of economic importance as biotite and garnet may both be recovered during the milling process. The kyanite bearing amphibolite gneiss of Northern Kyanite Mines' Wanapitei Kyanite deposits consists of one northerly and one southerly deposit, both trending easterly and extending 900 meters in central Dryden Township. The lithological similarities of these two zones are obvious excepting a noted presence of sillimanite and of pegmatite intrusions in the southern deposit plus an abundance of garnets in the northern band. Development of the ore lenses of this property was initiated by Pioneer Consultants Limited with the technical aid of the Department of Mines and Technical Surveys, Ottawa. An extension of this rock coincides with an occurrence of kyanite in Dill Township close to the Grenville Front Boundary Fault. (OFR5329, p.108)

Jun 09, 2009 (D Scholtz) - Fine- to coarse-grained, grey to dark grey, garnet-kyanite-muscovite-biotite-plagioclase-quartz gneiss, derived from aluminous argillaceous rocks, forms several thin units intercalated with other metasedimentary gneiss within a few kilometres southeast of the Grenville Front Boundary Fault in Dill and Dryden Townships. Although the gneiss contains up to 43 percent kyanite, most units of the gneiss are probably unsuitable as a commercial source of kyanite either because of their small size, or because the kyanite is erratically distributed throughout the gneiss. Moreover, the kyanite is locally altered to fine-grained sericitic material and commonly contains tiny inclusions of other minerals. Nevertheless, relatively large units of the gneiss north of the map-area in Dryden Township locally contain sufficiently large concentrations of kyanite to be of economic interest (see Pearson 1962, p.36-37), but no commercial production has been achieved. (R116, p. 141)

Jun 09, 2009 (D Scholtz) - Lumbers (1975, p.141) describes the geology of this showing which is a continuation of the Wanapitei Kyanite as: "Fine to coarse grained, grey to dark grey, garnet-kyantie-muscovite-biotite-plagioclase-quartz gneiss, derived from aluminous argillaceous rocks, forms several thin units intercalated with other metasedimentary gneiss within a few kilometres southeast of the Grenville Front Boundary Fault in Dill and Dryden Townships." Kyanite-biotite gneiss. (OFR5329, p. 118) As Lumbers (1975, p.141) concludes: "Although the gneiss contains up to 43 percent kyanite most units of the gneiss are probably unsuitable as a commercial source of kyanite either because of their small size, or because the kyanite is erratically distributed throughout the gneiss. Moreover, the kyanite is locally altered to fine-grained sericitic material and commonly contains tiny inclusions of other minerals."
