Ken, thank you for your wonderful journey through Trail.i found your site in attempting to make sense of a little dish with the TADANAC word stamped inside. Lead? Zinc? I wondered.

At one time the Cominco plants -- there were two within spitting distance of each other -- were the largest producers of lead-zinc in the world. The company also produced fertilizer at its nearby plant in Warfield (British Columbia). During World War Two, the Warfield plant produced the heavy water needed for the atomic bombs used on Japan. The company has since been taken over by Teck (a German outfit I think) and is called Teck Cominco. If I remember correctly each of those plates pictured above weighs about 50 pounds and in 1970 when I worked there were stacked by hand. Originally a smelter was built near where Trail Creek runs into the Columbia River in the late 1990s. It smelted the gold ore mined in Rossland, about 6 miles uphill from what is now Trail. When the gold ran out in the early 1920s, the company, Consolidated Mining and Smelting, shifted gears and started smelting lead zinc. CM&S eventually evolved into Cominco. Just a little history for you. Google Trail BC or Rossland BC for more. By the way, the area is now one of the top hiking, skiing, trailbike areas in the world. Quite unspoiled in the back country and worth a trip.

Tadanac is also the name of a neighbourhood in Trail (slightly upwind, upriver) from the smelter. That is where I spent a large part of my childhood.

This is Tadanac Brand zinc mined in Trail, BC and Greenland where the concentrate was shipped back to the Trail refinery. One of its biggest uses was to Oxidize it in a furnace and use the zinc oxide in Tyres and Paints also as dry battery covers where the chemical reaction produced electricity for portable appliance like torches radios etc. It was owned by Cominco and they by Canadian Pacific. Cominco was based mainly in Vancouver. I dont know now if Cominco still trades or who bought them but in the days I worked for them they were a very good company and although heavy industry were ecologically aware, in fact they supplied military spec alloys to the US for cathodic protection which were specifically developed to reduce heavy metal contamination.

The picture is of "Tadanac" brand ingots of 99.99% pure Zinc. Tadanac was a brand name of Cominco Ltd, and was produced in Trail, BC. The name was formed by putting a "T" in front of Canada spelled backwards ... so now you know!
