The deposit The zinc and silver-lead deposit was discovered in 1991 by Aberfoyle Resources Ltd. Following analysis of the regional geology the deposit was not deemed large enough to warrant further exploration and possible development. Terramin acquired the licences in 1997 and commenced an intensive drilling program to further define the mineral reserves.
