Sommaire: The Fond-du-Lac uranium deposit was delineated primarily by percussion drilling and a small program of diamond drilling. Drillcore samples from three diamond drill holes as well as digitized gamma logs from percussion and diamond drill holes were utilized to define and implement an algorithm for the conversion of gamma-log data to equivalent-grade data. The procedures and detailed analysis for the provision of assay data for uranium reserve estimation are documented.

Sommaire: Induced polarization/resistivity and magnetometer surveys have been carried out over the Casmo molybdenite deposit in mountainous terrain of northern British Columbia. Molybdenite occurs in quartz-bearing fractures with or without pyrite along a zone of hydrothermal alteration and intense fracturing, believed to be a northerly dipping fault zone, within medium-grained equigranular and porphyritic quartz monzonite.
The molybdenite-bearing zone is characterized by a significant resistivity low,...

Sommaire: Cominco Ltd.'s Polaris Mine, located on Little Cornwallis Island, Northwest Territories (latitude 75 degrees 30') went into production in late 1981, becoming the world's most northerly base metal mine. The concentrator, powerhouse, shops, offices, dry and warehouse, were uniquely designed and constructed on a 100 ft wide by 400 ft long by 65 ft high barge. This process barge was constructed in southern Canada, at Trois Rivieres, then towed 3,500 miles into the High Arctic Islands and beached...

Sommaire: Zinc, which once enjoyed an unchallenged position in the field of decorative applications, has lost a substantial share of its markets to other materials, particularly plastics. This turn of events has led the zinc industry to explore new market areas, particularly those applications where the engineering properties of zinc can be utilized. This paper gives an overview of the zinc industry's efforts to develop the data base and product development technology which have enabled zinc alloys to...

Sommaire: This paper describes the development of a milling circuit for the complex Midwest orebody, containing a high-arsenic uranium ore typical of that found in northern Saskatchewan. The results of preliminary bench-scale testwork are summarized. Data from a pilot-plant program carried out at the Ontario Research Foundation are provided for the selected mill flowsheet. Also described are waste circuits which have been established to produce effluents of acceptable quality. Pilot-plant testing of...

Sommaire: Sample drops were evaporated on Lexan disks on which fission tracks were etched and counted after neutron irradiation. [U] < 0.01 ppb could be measured. This method is rapid, cheap, simple and accurate when sufficient control and checking is possible, but several types of error were encountered in its use, the natures and sources of which were investigated but not always determined. The most troublesome were "annealing" processes which sometimes altered the fission tracks so that...

Sommaire: Over the years, ore geologists have made innumerable observations as to the relationships of certain kinds of ore deposits to particular types of rocks and to the types of primary and secondary structures that these rocks contain. On the basis of these, the places in which to look for new ore deposits are more clearly defined than they would be in an exploration program based largely or solely on concepts of ore genesis. This paper discusses the affinity of certain rock types and structures...
