Beyond the significant tailings resource, three in situ resources provide the ability to expand production or increase mine life beyond processing of tailings. The total JORC compliant Indicated and Inferred Mineral Resources is 9.3Mt at 6.1% Zn, 4.7% Pb and 66g/t Ag for 568,000t contained zinc, 433,000t contained lead and 19,850,000oz contained silver.

The Century tenements host substantial phosphate mineralisation in the Phantom Hills Deposit and other minor deposits, located directly to the NE of the Century open pit. In 2013, a 14,300m RC and diamond drilling program was completed over the phosphate deposit area. Despite the extensive drilling to date, a defined resource for the Phantom Hill Phosphate Deposit is yet to be estimated. Conversion of the Century infrastructure to support a phosphate rock processing operation presents a low cost and low risk option to extending the life of Century operations and infrastructure beyond zinc and lead processing activities.

Excellent exploration potential remains at Century for the discovery of smaller scale high grade deposits within the 783km2of mining licences and the exploration permit. Despite the tenements being located in the highly prospective Termite Range Fault district, since 1990 exploration has been predominantly focused on a relatively narrow strategy targeting further discovery of large sediment hosted Zn/Pb/Ag deposits of similar scale to the original Century deposit. The large scale Century deposit was located in the middle of a 20km diameter cluster of smaller high grade vein breccia lodes. exploration work has occurred on these high grade targets, providing potential for adoption of a revised strategy targeting delineation of smaller high grade deposits. These vein breccia lodes form distinct ridges and outcrops opposing the recessive siltstone and shale members throughout the mineral field. Over 40 of these lode targets have been recorded to date, with the l...
