RL-1 Certificate of Analysis
Certified Reference Material: Uranium Ore
Printable version of the certificate (PDF, 704.37 kb)
RL-1 is a sample of ore from the Rabbit Lake deposit of Eldor Mines, Saskatchewan. The host rock is a siliceous dolomite that has been highly altered and fractured. The orebody consists of a high-grade uranium mineralization in the centre of a brecciated zone, varying to low grade in the lesser brecciated perimeter. RL-1 was intended as a higher uranium-bearing complement to uranium tailings sample UTS-4, previously prepared from a sample of the same orebody.
Thirteen laboratories participated in the interlaboratory program to provide analytical results for one or more of uranium, nickel, and arsenic.
