Abstract The Chadbourne Project, located within the limits of the town of Noranda, Quebec, will make use of backfill materials to fill the voids left by the mining of slopes and pillars. A series of tests were conducted on different mixtures of slag and pyr-rhotite tailings materials to evaluate their properties. The tests are described and some pertinent results are given in the paper.
