Owners of re-opening Century Mine, New Century, say they have identified a new mineral resource at South Block with high recoveries of zinc, lead and silver.
The company said they have identified 6.1Mt at 6.8% zinc-lead containing 322,000t zinc, 90,000t lead and 8.5Moz silver.
In a release to the ASX New Century said it was well advanced in assessing potential for South Block development.
“Preliminary metallurgical testwork demonstrates recoveries of up to 82% zinc, 85% lead and 83% silver through the existing Century Processing Plant,” the company said.
South Block is located on the south end of the original Century ore body and is adjacent to the existing Century Processing Plant.
The company said the South Block Indicated Mineral Resource complements already defined resources at two other blocks demonstrating a “significant upside” for operations beyond the recently announced restart Feasibility Study for the Century Tailings Deposit.
The company drilled two diamond drill holes through the central region of the deposit.at South Block to obtain representative samples which were used to validate the Indicated Mineral Resource estimate, and for metallurgical test work and metal recovery assumptions.
In September 2017 New Century entered an agreement with the Waanyi ReGen Joint Venture between Waanyi Enterprises and Downer EDI Mining to assess the feasibility of open cut mining operations at the Century Zinc Mine, centered around South Block.
The JV represents the Waanyi People (traditional owners of the lease area) and Downer Group and as part of the Collaboration Agreement, New Century engaged the WRJV to carry out an initial assessment of mine design, engineering and costings for the development of South Block.
This initial assessment has demonstrated the potential for inclusion of South Block into the planned operations of the Mine.
The results will form the basis for New Century's planned Expansion Feasibility Study.
