DESCRIPTION OF DEPOSIT
The quarry is situated on a low anticlinal ridge about 0.8 km wide and 4.8 km long that trends northwest-southeast. The covering of soil varies from 2 to 4 m along the axis and deepens on both flanks. Tyndall stone is a mottled dolomitic limestone and at this locality is in the lower half of the Selkirk member of the Ordovician Red River Formation. The rock is composed of a matrix of light buff limestone in which occur tubular and interconnected mottled areas of brownish dolomitic limestone and at this locality is in the lower half of the Selkirk member of the Ordovician Red River Formation. The rock is composed of a matrix of light buff limestone in which occur tubular and interconnected mottled areas of brownish dolomitic limestone forming one third of the rock and distributed uniformly throughout it. The upper 2.5 to 5 m is buff in color, the next 4 m has a grey to bluish cast, while the remaining 10 m (unquarried) is lighter colored. Large fossils, usually white are scattered through the rock but the stone can be cut to avoid these. The stone occurs in "beds" caused by stylolitization of 0.5 to 1.8 m thick. (See Fig. 1 on the back of this sheet). The beds have been lettered 'A' to 'K'. Increasing amounts of chert have been found below the 'I' bed.
Chemical Properties: Analyses of individual, quarried beds range from 83.21 to 89.26% CaC03 and 14.91 to 9.43% MgC03. See Goudge, 1944.
Physical Properties: For Physical properties relating to the use of the stone for building purposes see Parks (1916).
Uses: Building stone, Monumental and Ornamental Stone, Flagstone, crushed stone, lime (pre-1942); also used in sulphite pulp industry.

HISTORY OF EXPLORATION AND DEVELOPMENT
Gillis quarry is located on the south side of Hwy. 44 in l.s. 13, sec. 3, at Garson, 48 km northeast of Winnipeg.
1898: John Gunn opened a limestone quarry on privately held land.
1905: The quarry was owned and operated by John Gunn and Sons, Winnipeg. Channeling machines, steam-and-horse powered derricks were being used. Dimension stone, Rubble, crushed stone for lime were being produced. The lime was produced in two draw kilns. Tram cars carried the crushed stone from the quarry to the top of the draw kilns, while the lime was drawn from the bottom and carried by wheel-barrows to box cars on the spur line.
1916: W. Murray was operating the quarry which he leased from John Gunn (Parks, 1916). After the overburden and upper shattered beds had been removed, a channel cut was run across the quarry about 1.5 m back from the face. Two cross channels were made at each end of the strip and the key block removed. The strip was raised by plug and feathers then cut into lengths of 2 to 4.5 m by plug and feathers.
1925: By 1925 Gillis Quarries Limited (incorporated in 1922) was shipping 3 to 4 cars of stone a week to their dressing plant in Winnipeg. They burned lime and shipped rubble as well.
1933: The overburden was removed under contract by dragline excavator. Steam channeling machines channelled sections of the floor 9 to 12 m square and divided it into strips about 1.5 m wide. The 2 or 3 beds included in each cut were raised by wedges in horizontally drilled holes. Then the beds were cut into mill blocks by plug and feathers. Wooden guy derricks were employed for raising blocks from the quarry and for stockpiling (Goudge, 1933 p. 109 - 112).
1944: The quarry measured about 120 m square and was 7.3 m deep exclusive of overburden. The kiln hadn't been operating since 1942 and the company was dressing only stockpiled stone. During this period, stone was shipped also to dressing plants in other cities.
1948: Expansion of the pit to the west was begun. The steam channelling machines were still being used. 4200 tonnes of building stone, 960 tonnes of crushed stone, and monumental, or namental and flagstone were produced. The stone was trucked to the dressing plant in Winnipeg for cutting and polishing.
1965: After peeling back the overburden with bulldozers and front end loaders channelling was done with a steam channerller for beds 1.8 m thick. Beds less than 1 m thick were cut with a new diamond circular saw (blade 244 cm in diameter); strips 1.8 m wide by 24 m long were cut at the rate of 56 cm a minute. The stone was then split into 5 to 7 tonne blocks for shipping to the dressing plant in Winnipeg.
1969: Construction of a dressing plant at the quarry site was begun. It went into production in 1970.
1972: By 1972 the quarry was 400 m long at the longest point by 285 m at the widest point.
1973: About 1973 Gillis Quarries moved quarrying operations to the old Tyndall Quarry Company Limited Pit (see 62I/2 STN 3 card).
1976: The dressing plant was expanded and all finishing operations are now carried on in Garson.
1978: The average yearly production is 22500 tonnes. Since 1973, the only site being quarried is in l.s. 15, the western end of the old Tyndall quarry. Some blocks stockpiled for many years are being used also.
HISTORY OF PRODUCTION
1898: John Gunn opened a limestone quarry.
1905: Dimension stone, rubble and crushed stone, for lime were produced by John Gunn & Sons, Winnipeg.
1916: W. Murray operated the quarry.
1925: Gillis Quarries Limited operated the quarry. They were shipping 3-4 cars of stone a week to their dressing plant in Winnipeg and burning lime. They shipped 50 cars of rubble.
1942: 1942 was the last year Gillis burned lime.
1944: The company was dressing only stockpiled stone.
1948: 4200 tonnes of building stone, 920 tonnes of crushed stone and monumental and flagstone were produced.
