HISTORY OF EXPLORATION AND DEVELOPMENT
Cameron (1949) reported:

Neepawa Wells
In the Neepawa area two wells encountered strong flows of brine which rose to within 300 feet of the surface. Brine flows at 1,185 feet and 1,460 feet, analysed 17 per cent dissolved salts, over 85 per cent of which was sodium chloride. Typical well brine analyses are as follows:
% Gms. Gms.
By Weight1 Per Litre1 Per Litre1
Sodium Chloride (NaC1).............15.40..............174.2..................181.528
Calcium Chloride (CaC12).............0.66..................7.5.....................8.042
Magnesium Chloride (MgC12)....0.41..................4.6.....................4.603
Potassium Chloride (KC1)............0.36..................4.0.....................0.031
Calcium Sulphate (CaS04)............0.36..................4.0.....................4.073
Bicarbonate, Ammonia, Lithium
and Bromide Traces...............4.0
Total Solids.......................................17.2
Specific Gravity (15 C).....................1.1305

These analyses show that there has been little change in the composition of the brines from the time they were tested as reported by Wallace in 1927 to the present, except for an increase in the potassium chloride content.
The Neepawa Salt Company was formed in 1932 to develop the wells and erect a plant for the production of salt. In 1935 Canadian Industries Limited purchased control of the Company and now operate the Neepawa plant as one of the units of their salt division.
During the years 1932 to 1940 the production from the plant averaged 3,000 tons of salt per year. However, in 1940 production was increased to over 13,000 tons and rose to a maximum of 27,133 tons in 1945. Output now ranges between 24,000 and 26,000 tons per year, the brine being treated by the vacuum pan process which produces a full range of fine salt products including table, dairy, and pressed blocks. Any of these products may be obtained iodized if desired. In addition to sodium chloride the Neepawa operations include the recovery of the chlorides of calcium, magnesium and potassium, in dry form, which are marketed as flaked chlorides for dust control and for the filling of tractor tires.
Bannatyne (1960) reported:
At present, salt is produced only by the Canadian Salt Company Limited at Neepawa. Salt is precipitated by the vacuum pan evaporation process using subsurface brines recovered from 2 wells at the town of Neepawa. The brines have been tapped at 2 horizons: the upper, at a depth of 1,160 feet, from a porous zone in the Souris River formation, and the lower, at a depth of 1,453 feet, from the Winnipegosis dolomite. The source formations have been determined by a comparison of the sample log of the Neepawa #2 well (9-33-14-15W) with the logs of neighbouring wells, as shown in figure 5. These brines have a total dissolved solid content of 170,000 to 180,000 ppm, of which NaC1 forms more than 85 per cent. The concentration has remained essentially constant from the time of first production in 1932 to the present. Production now is about 23,000 tons of salt per year. The combined chlorides of calcium, magnesium, and potassium, in dry form, are recovered as a by-product (see also Cameron, 1948).
