DESCRIPTION OF DEPOSIT
The “black granite” is a border phase of the Archean or Proterozoic Falcon Lake Stock. Actually a diorite, the dark colour is due to the greater translucency of the plagioclase than that of normal diorite, and the resulting absorption of light by black biotite and hornblende. Minor amounts of sulphides are present in the diorite.

HISTORY OF EXPLORATION AND DEVELOPMENT
The “black granite” quarry is located immediately west of the “old” road joining West Hawk and Falcon Lakes, approximately 1½ miles west of the village of Westhawk Lake.
The 40 acre property was staked by L. H. Sprange (Q.C. W17) in 1937, leased for 10 years by him (M38) in 1944 and for 10 years by his sons (M113) in 1954. The first pit, opened in about 1938, contained an excessive amount of sulphides. A new quarry was opened where the sulphide content was lower. Monumental and decorative building stone under the name “Winblack granite” were produced up to 1952 and in 1964 the lease was cancelled. The stone was apparently produced in the name of the Winnitoba Marble Company Limited, but marketed by the Memorial Marble and Tile Company, Limited. Both companies were owned by the Spranges.
In 1965 N. Saroka (Q.C. W1194) restaked the north half of the property (19.9 acres), but in 1966 he assigned all interest to the Norlica Minerals Ltd. No work was reported and the permit was cancelled in 1971.
An adjacent 40 acre claim in Sec. 8 was staked by I. P. Kahlert (Q.C. W624) in 1961 for the Cold Springs Granite (Canada) Limited, in order to determine if granite of good quality is present in sufficient volume to warrant a commercial operation. The permit was cancelled in 1963 when it was learned that the Hudson Bay Company held the rights to all minerals except gold and silver on the property.
