Includes bibliographical references. “A copper-molybdenum ore, HV-1, has been prepared and characterized for use as a standard reference material. HV-1 is the third ore of metallic minerals to be issued for sale as part of the Canadian Standard Reference Materials Project, of the Mines Branch, Department of Energy, Mines and Resources. This report gives the mineralogical, geological and chemical characteristics of HV-1, as well as some details of methods used for its comminution and blending, and for assessing its homogeneity. Twenty-three laboratories provided analyses for copper and molybdenum; the recommended mean values for these are: 0.52% and 0.058%, respectively. The analytical results and the evaluation of statistical parameters for copper and molybdenum are reported"--Synopsis, p. i.
