- Geological Details
- The occurrence is located at the approximate geographic center of the main part of Hungry Island, 1.7 miles (2.7 km) south of the northern end of the island.
Hungary Island, as mapped by R. Wallis, is underlain by the Trout Narrows granite or Archean unit Wfn which consists of a medium- to coarse-grained, well foliated to gneissic, biotite±hornblende syenogranite to granodiorite with local inclusions of amphibole and/or pelite. On the north third of the island, the above-described granite is unconformably overlain by basal Wollaston Domain unit Wpsn or fine- to coarse-grained, foliated to gneissic pelitic to psammopelitic gneiss with local interlayers of psammite and calc-silicate rock or amphibolite.
The Trout Narrows granite lies in the core of a regional, northeast-trending synform. The rocks in the showing area have been cross-cut by a series of north-trending faults.
The occurrence consists of large 6 mm (0.24 inch) elongate, xenoblastic, poikiloblastic, porphroblasts of cordierite which tend to concentrate along particular layers in strongly foliated, fine to medium grained, gray, biotite-quartz-plagioclase psammite of the Aphebian Daly Lake Group of the Wollaston Fold Belt. Abundant segregation pegmatite is associated. The units strike northeast and dip 40 to 65° NW.
The occurrence has no economic significance.

- Exploration History
- 7/13/1988 The occurrence was first mapped by R.H. Wallis in 1969.
Prospecting was first carried out in this area by E.F. Partridge in 1966. Nothing of interest was noted and the area was abandoned. The area remained inactive until 1968, at which time it was covered by the Gulf Minerals Canada Limited Permit No. 11. Some general reconnaissance mapping was done the following year but nothing of importance was noted. No further work was done and Permit No. 11 lapsed in 1973.
