 MINERALS YEARBOOK, 1972876 
 Botswana.—The way was cleared for development of the Pikwe-Selebi
coppernickel deposits when agreements for financing the project were signed
at Gaborone in March. 
 Canada.—Canadian nickel production in 1972 was 13% less than in 1971
because INCO cut back its mining operations 10% early in the year to adjust
output to market conditions. At yearend INCO had 14 mines operating, 11 in
Ontario and 3 in Manitoba. INCO's Maclennan mine in the Sudbury district
was depleted, and its Shebandoan mining and milling complex in Northern Ontario
was brought into production as planned. 
 Prospecting and exploration of nickel and copper-nickel properties continued
at a high level of activity, little influenced by the worldwide imbalance
between supply and demand. INCO a-nd Falconbridge Ni-ckel Mines Ltd. were
active in exploration in Quebec, Ontario, and Manitoba. INCO did not report
developments at specific properties in its annual report for the year. Fakonbridge
reported that underground driffing at its Onaping mine indicated a new significant
sulfide zone and that diamond drilling from a drift on the 1,000~foot level
at the Bucko Lake property of Bowden Lake Nickel Mines Ltd. was in nickel
mineralization. Falconbridge had a 60% interest in the property. 
 Great Lakes Nickel Ltd. of Toronto, Ontario, and Boliden AB of Stockholm,
Sweden, announced an agreement under which the Swedish company will study
the feasibility of producing copper and nickel concentrates from the large
low-grade copper-nickel property on which Great Lakes Nickel has indicated
106 million tons of 0.4% copper, 0.2% nickel ore. A feasibility study made
for the Ontario Government indicated that a copper smelter-refinery in northern
Ontario would not be economically viable unless large copper ore bodies are
discovered. The study cited the Great Lakes Nickel Ltd. project as a possibility.
 The principal Canadian nickel producers and their 1972 production, sales,
or deliveries to customers as given in their annual report to stockholders
were as follows:

 Environmental improvement in the Sudbury district was a major element in
the operations of both INCO and Falconbridge. INCO commissioned a 1,250-foot
chimney and a gas cleaning system and capped the three chimneys that it replaced.
Falconbridge shut down its pyrrho. tite processing plant until a process
is developed to eimi-nate sulfur dioxide (SO2) emissions. Both companies
recycled processing waters and seeded barren land in the vicinity of their
plants. 
 Falconbridge closed i-ts nickel-iron refinery after 2 years of operation
failed to achieve continuous production of specification products. Reports
-to the Bureau of Mines from U.S. consumers of the Falconbridge nickel-iron
indicated that the material that reached the market was a satisfactory source
of nickel for use in steelmaking. 
 Colombia.—Colombian Nickel Co. (CONICOL) and the Industrial Development
Institute of Colombia (IFI) were renegotiating portions of their concession
agreement to exploit nickel deposits at Cerro Matoso i-n the Department of
Córdoba. 
 Cuba.—The Government of the Republic of Cuba announced that it had
reached agreement with the Government of the U.S.S.R. for credits to finance
general repair and reconstruction of the existing nickel plants at Moa Bay
and Nicaro and to expand the mining base at both plants. Moreover, it announced
that Cuban and Soviet organizations will collaborate on construction of the
first phase of a mining-metallurgical complex with an annual output capacity
of 30,000 tons of nickel and cobalt at Punta Gorda. The approximate distribution
of credits for the projects was 52 million rubles (US$63.18 -million) for
rehabilitation of Nicaro and Moa Bay and 15 million rubles (US$18.225 mifflon)
for the Punta Gorda complex. The ultimate investment needed to raise Cuban
production to 90,000 tons of nickel annually was estimated at $600 million,
not including the funds required for the infrastructure, housing, and energy.
 Dominican Republic.—The -ferronickel plant of Falconbridge Dominicana
C. por A. was officially inaugurated by His Excellency Dr. Waukeen Balenguer,
President of the Republic. The plant produced about 46,000 tons of ferronickel
during the year,
