Point Location Description: Quarry

Location Method: Data Compilation

Access Description: The quarry is located in Docker Twp. approx. 12 km west-southwest of the town of Vermillion Bay, on the north side of hwy. 17, north of Aaron Lake.

Exploration History

1948: rock has been quarried from this deposit since 1948 by various companies. 1981: Nelson Granite Ltd. opened their quarry, directly south of the Vermillion Pink quarry, across Highway 17. 1994: Nelson Granite was producing from a quarry north of Aaron Lake which is due north from the old quarry. Produced 40,258 cubic meters of Vermilion pink stone from 1994-2000. 1994-95: Nelson Granite carried out power stripping. 1996: Nelson Granite drilled 4 DDH for 48.8 m. Production continued up to and throughout 2019. 2020: quarry does not show as having an active permit.

Geology Comments

Dec 07, 2005 (W Bellinger) - The quarry is hosted within the potassic suite of granites of the synvolcanic Dryberry Batholith in the Wabigoon Subprovince (Blackburn et al. 1991). Storey (1986) described the previous work dealing with the quarry: The area was mapped by Pryslak (1969, 1976) and included in a reconnaissance scale map by Breaks et al. (1975f, 1978). The quarry was described by Carr (1955), Guillet (in Hewitt 1964); Pryslak (1976) repeated Guillet's description. The deposit is mentioned in Vos et al. (1982). The rock is homogeneous, massive, medium grained pink granite. The body is egg shaped in plan, 2.8 by 1.8 km. This is the same deposit that the Granite Quarriers (GQI) Inc. quarry is located in and the rock is identical. The rock is very uniform in colour. A few minor quartz veins up to 2 cm wide are present.

Lithology Comments

Dec 07, 2005 (W Bellinger) - Storey (1986) described the mineralogy of the granite: The rock was classified as quartz monzonite by Mattinson (1952) and granite by Pryslak (1976). A modal analysis from Mattison (1952) plots as granite in the Streckeisen (1976) classification. 'There is a slight layering parallel to the sheeting. This is evidenced by a slight lightening of the pink colour of the feldspar. Biotite is roughly aligned parallel to these layers. This effect is present in several places in the deposit. When present the layering forms lines 2 cm apart on the surface. Microcline crystals up to 1 cm form dark pink phenocryst-like forms although the texture is not porphyritic.' The granites are characterized by the abundant coarse-grained microcline in irregular anhedral crystals up to 5 mm in size. Plagioclase feldspar (albite) is found in granules of similar size. It is usually slightly altered and does not always show its sharp multiple twinning. It also carries micrographic inclusions of quartz at some if its contacts with potash feldspar producing a textural feature called myrmekite. Although the latter is not a mineral, its ubiquity in the rock is worthy of note in the table. Quartz occurs interstitial to the feldspar. It is somewhat smaller in grain size, sometimes showing strain. In places, it is found as small inclusions in the large crystals of feldspar as well as in the myrmekite noted above. Biotite mica is the sole ferromagnesium mineral in the granites. It is disseminated through the rock in small clusters of two to four flakes in a uniform manner. In a few places, it has been replaced by chlorite. Generally, the mica is fresh and unaltered. No sulphide minerals are evident in either granite sample.
