The CIM Definition Standards on Mineral Resources and Reserves (CIM Definition Standards) establish definitions and guidance on the definitions for Mineral Resources, Mineral Reserves, and mining studies used in Canada. The Mineral Resource, Mineral Reserve, and mining study definitions are incorporated, by reference, into National Instrument 43-101 – Standards of Disclosure for Mineral Projects (NI 43-101).

To investigate the ability of komatiites to preserve during alteration a record of the geochemical and isotopic composition of the Archean mantle, we studied the petrology and geochemistry of a komatiite flow from Alexo, Ontario. Although this flow is relatively well preserved, two main types of alteration are recognized: (1) hydration of variable intensify throughout the whole flow; (2) local rodingitization. In samples only slightly affected by hydration, the alteration was essentially isochemical;

Wawa has long been a center of mineral exploration activity and diamonds have been reported in the area since the 1930s. However, diamond exploration did not begin in the area in earnest until 1991. In 1993, Sandor Surmacz and Marcelle Hauseux of Saminex began a prospecting program in the area which culminated in their discovery of the “Sandor” diamond occurrence in an outcrop on the east side of the Trans-Canada Highway.

Landsat Thematic Mapper [TM) data have been used to detect the presence of altered rocks associated with ore mineral deposition. In arid environments, the spectral signatures of diagnostic minerals are often not masked by water, vegetation, or suxficial materials. There are many studies in which TM data have been used to locate hydrothermally altered rocks in near desert regions, but few successful examples can be found that relate to glaciated, vegetated terrain at high latitudes. In this paper, TM data, in concert with lithogeochemical data and field observations, are used to detect and map altered rocks in the Sulphurets-Brucejack Lake district of northwestern British Columbia.

A nation’s endowment of nonfuel mineral resources, relative to the world’s endowment, is a fundamental consideration in decisions related to a nation’s economic and environmental well being and security. Knowledge of the worldwide abundance, distribution, and general geologic setting of mineral commodities provides a framework within which a nation can make decisions about economic development of its own resources, and the economic and environmental consequences of those decisions, in a global perspective. The information in this report is part of a U.S. Geological Survey (USGS) endeavor to evaluate the global endowment of both identified and undiscovered nonfuel mineral resources.

The Upper Cretaceous rocks of southeastern Vancouver Island contain important coal deposits, which have been known for more than a century and have long provided British Columbia with a major industry. Gradual depletion of the more accessible reserves has resulted in efforts both by company officials and, from time to time, by Government geologists, to acquire additional structural and stratigraphic information that might serve to prolong the life of these deposits <...>
