NAME OF PROPERTY
McArthur Mine, Muir Farm
Coal of the Tertiary Turtle Mountain Formation was formerly mined at
McArthur's Mine to be used as a local source of fuel for homesteads.
According to Dowling (1906) a long ravine running from the mountain in sec.
1-2-23 W, passing through sec. 11, 14 and 15, is cut down through about 12.1 m
of the rocks, but the exposures along the sides are concealed by surface
deposits. A small exposure of sandstone can, however, be found on sec. 15. The
coal seams evidently should crop out on the sides of this ravine, as they have
been found by boring in the centre of sec. 11 at the bottom of the ravine near
Mr. Duncan McArthur's house. Here three seams were found with thin clay
partings and the two upper ones are thick enough to work. Subsequently, a shaft
was sunk from higher ground and for several years a small quantity of coal was
taken out during the winter months.

EXPLORATION AND DEVELOPMENT
The mines are located approximately 5.7 km south of Deloraine on
According to Bannatyne (1978) the McArthur Mine was
operated intermittently between 1893 and 1908. Several shallow pits were
operated and then a 15 m shaft was sunk to lignite, 1.5-1.8 m thick, at a depth
of 10.5 m. Either one seam, or two seams each 0.7 m thick were present,
separated by up to 0.45 m of clay. A third, thin seam was reported a short
distance below, but not worked. The seams dip slightly to the north. The mine
was re-opened by two Welshmen who were not able to carry on during 1908. The
mine was very wet, and some difficulty was encountered with the roof. The
location is west of the ravine, on the south side of l.s. 14 (Mineral Resources
During October 1931, the Deloraine Coal Company Limited was
incorporated to develop and operate coal mines on the NW1/4 of Sec. 11-2-23 W
(Muir Farm). Development work by the company was started in a ravine adjacent to
the old McArthur shaft, almost in the centre of the section. An adit was
driven on an incline of 25° from the floor of the ravine into the west bank. The
coal (lignite) was intersected 3.0 m to 3.6 m below the floor of the ravine at a
distance of 27.3 m from the opening. The coal seams, besides appearing thin and
irregular, pitched at a considerable angle (25°) to the northwest.
working of the company was also in l.s. 14, 304.8 m north of the McArthur
shaft. A small quantity of coal was taken from the upper seam and then the
working was abandoned in October.
A second shallow trench also in l.s. 14,
was then cut at a point 114.2 m farther south of this first working, but no coal
was encountered. Later a shaft, 4.2 m x 4.2 m was sunk at a point 30.4 m south
of the old McArthur shaft. Development work proceeded under difficulty
owing to caving of the walls to a depth of 13.9 m. This shaft was in turn
abandoned and activity transferred to a point 45.6 m northwest of the old
McArthur's Shaft, where an incline 2.1 m x 2.1 m was started in a
southerly direct to tap the lignite in the vicinity of the old McArthur
workings. The elevation of the entrance to the incline was made as an open-cut
and then followed an adit, 55.6 m from the entrance of which coal was
The elevation was 11.5 m below that of the entrance. At a point
19.7 m from the adit entrance the direction changed to the southwest and at 41.0
m was another turn with the heading of 257°. Here the coal occurs in two seams
pitching 14°N and 7°W. The seams vary in thickness, the lower 60 to 103 cm, the
upper 25.4 to 30.4 cm and are usually separated by 30.4 cm to 45.7 cm of sand
and clay though in places the seams come together giving a continuous thickness
of 1.1 m of lignite.
In an endeavour to indicate a favourable area for mining
the lignite two drill holes were put down in the vicinity of the shaft, the
first, located 22.8 m southeast from the shaft cut a 0.6 m seam of lignite coal
at a depth of 38.9 m. The second hole, put down at a point 109.6 m west of the
first, failed to intersect any coal in 37.9 m of drilling. Operations were
carried on until the end of 1931, and 544 tonnes of lignite were produced during
Work was resumed at the Muir Farm (sec. 11-2-23W) on March 12,
1932, and was continued, except for a period of 3 weeks in May until October.
The Deloraine Coal Company operated the property until August 8 with a crew of
about 12 men. Work was confined to driving two inclined drifts to the north from
the main entry in an endeavour to locate the main McArthur seam.
August 8, J.E. Carruthers took charge and the name was changed to Turtle
Mountain coal Mines. A Lidgerwood double-drum hoist, steam driven, was installed
to haul cars from the mine. Two seams each 0.8 m thick separated by about 0.9 m
of sand and clay, were worked for a while and about 54 tonnes of coal produced.
But according to the arrangement of the workings it was only possible to work
down the seams which pitched at a high angle to the northwest and operations
were not successful. The property was abandoned in October.
According to the
Annual Report (1932) J.E. Carruthers moved his equipment from the Muir Farm to
the Hainsworth Farm L.S. 4-14-2-23W, in October. An inclined drift on a 1 to 3
slope was started on October 24, 1932 from the floor of the ravine in a
southwesterly direction in an effort to locate a coal seam. Work continued until
the end of the year. No coal was mined.
After 1932 there has been no activity
at the Hainsworth Farm Quarry
1893 to 1908: Intermittent production of coal occurred on l.s. 6 of
sec. 11-2-23W during these years. Work consisted of the sinking of several
shallow pits and one - 15 m shaft. Production records are unavailable.
The Deloraine Coal Company, Limited was incorporated during the year to develop
coal from the NW 1/4 of sec. 11-2-23W. The company sank an adit into the side of
a ravine located on the property. A small quantity of coal was removed from the
upper seam and the workings were abandoned in October. Following some trenching
in the ravine, a 4.2 m x 4.2 m shaft was sunk south of the McArthur shaft
but not production was recorded. In an attempt to outline favourable areas of
coal mining the company put down two drill holes near the mine shaft. Operations
were carried out until the end of 1931, and 544 tonnes of coal were produced
during the year.
1932: Work was resumed on March 12, 1932 and was continued,
except for a period of 3 weeks until August 8. Work was confined to driving 2
inclined drifts to the north from the main entry. On August 8, J.E. Carruthers
took charge of the operation and the company name changed to Turtle Mountain
Coal Mines. Two seams, each 0.8 m thick separated by about 0.9 m of sand and
clay, were worked for awhile and about 54 tonnes of coal produced.
Carruthers moved the operation from the Muir Farm to the Hainsworth Farm in
October 1932. No lignite was mined.
1932 - 1996: There has been no production
at this quarry during this time.
