Description

CUP-2 is a uranium ore concentrate reference material produced as joint effort between CCRMP and the Analytical Subcommittee of the Canadian Uranium Producers Metallurgical Committee.

The material was received from the Blind River refinery of Eldorado Resources Ltd. in the summer of 1986. It was blended, checked for homogeneity by X-ray fluorescence analysis, bottled in 25-g units and distributed for analysis.

Certification project

CUP-2 was characterized by an interlaboratory analysis program. Eight member laboratories of the Analytical Subcommittee, six commercial laboratories, and three additional volunteer laboratories participated in the project by providing five replicate results on up to 17 analytes. Uranium was reported on a dry basis; all others were determined on an "as received" basis.

The purchaser, by receipt hereof, releases and indemnifies the CanmetMINING from and against all liability and costs arising out of the use of this material and information.
