Seven metal fragments were located in 1969 at the Thule Age (ca. 12O0) site of Silumiut on the western coast of Hudson Bay, four of native copper and three of iron. No forming technique other than cold hammering appears in evidence. Almost no sources of metallic iron are found in the Canadian Arctic. Analysis of the three iron fragments could identify two with the Cape York (Greenland) meteorite. The third is a wrought iron of.06-.12% carbon content and represents the most southerly find of Norse iron (and the earliest radiocarbon dated) in the central area. A very long distance trade network for iron is seen to have existed 40O years before direct European contact. -- AATA
