1444 MINE(RALS YEARBOOI<, 1941

Pembroke, Nova Scotia. Production in Canada during 1940 was Qnly 307 metric
tons, whereas in 1941, largely because of the above-men.. tioned operations,
it rose to 6,043 metric tons. Most of this came from the Nova Scotia deposit,
but a few hundred tons were shipped from a deposit near Golden, British Columbia,
most of it to a grinding plant in Montreal and the remainder to oil wells
in Turner Valley.4
 The Pembroke barite deposit in Nova Scotia is owned by the Springer Sturgeon
Gold Mines, Ltd., and operated by its subsidiary, Canadian Industrial Minerals,
Ltd. Two recent papers by Cameron5 and Campbell° describe the deposit,
the barite, the mine and mill operations, and possible markets. The barite
is hard and massive and is gray to dark red, replacing iron-bearing calcareous
sediments.

 Quarrying operations, and the construction of a 100-ton mifi at tidewater
at Walton on the Midas Basin arm of the Bay of Fundy, were commenced in February
1941. The mill was put in operation late in May 1941. Ore containing admixed
impurities is treated at a washing plant adjacent to the quarry to remove
the impurities before it is trucked to the mifi over an all-weather road.
The first shipment of the ground barite (96.85 percent BaSO4) was made to
Trinidad m June 1941. Several other shipments have since been made to Tnmdad
and one small shipment to Peru. In addition, about 100 tons of ground
