KC-1a Zinc-Lead-Tin-Copper-Silver Ore

Click to print PDF version of original certificate.

KC-1a was prepared from material hand-picked at Kidd Creek Ltd. (now a division of Falconbridge Ltd.) in Timmins, Ontario. The ore is from a zone of massive sphalerite-pyrite containing native silver and galena. KC-1a is intended to replace KC-1, the stock of which is exhausted. It serves to complement the certified base metal ore MP-1a which contains lower zinc and silver but higher lead, copper, and tin values.

Mineralogical Composition

Mineral Mass % Sphalerite 51.7 Quartz 21.4 Pyrite 17.1 Galena 2.6 Chalcopyrite 1.8 Cassiterite 0.8 Silver 0.16 Carbon 0.02

Certified Values and 95% Confidence Intervals

Constituent Mass % Zn 34.65 ± 0.15 Pb 2.24 ± 0.03 Cu 0.629 ± 0.015 Sn 0.61 ± 0.02 Ag 0.167 ± 0.002

Nineteen laboratories participated in the interlaboratory program to provide analytical results for five elements in KC-1a.

A certificate of analysis will be issued with each order of KC-1a. A copy of CANMET Report 84-6E, "KC-1a: A certified reference ore", will be forwarded, free of charge, on request to the Coordinator, CCRMP.
