ENCOURAGING drilling results at Millennium Minerals’ Nullagine gold project could enlarge pit designs prior to planned production at the mine’s Crow and Condor deposits, according to recent reports from the company. The deposits lie within the Golden Gate area of the 1.24 million ounce Nullagine project, in the East Pilbara district of WA. A total of 15 reverse circulation holes for 987m were completed at the Condor and Crow deposits. Highlights from Crow included: 6m grading 7.17 grams per tonne gold from 48m; 3m grading 2.41g/t gold from 43m; and 2m grading 3.15g/t gold from 18m. At Condor the best results were: 9m grading 4.77g/t gold from 75m; 6m at 3.28g/t gold from 8m; and 4m at 4.06g/t gold from 18m.
In a statement to shareholders on November 24 the company said moderate to high-grade intersections occurred adjacent to, or immediately beneath, the current proposed pit designs at Condor and Crow, and showed excellent potential to enlarge the pit designs prior to planned gold production in the fourth quarter of 2012.
The Nullagine project has a JORC-compliant measured, indicated and inferred resource estimate of 34.28 million tonnes grading 1.13g/t gold. As of November, new ore reserve estimates for all Golden Gate deposits were being undertaken and were expected to be
completed before the end of 2011.
According to Millennium, exploration within the Golden Gate area will now be ramped up further, with an additional 6000m drilling program planned. The company will also complete new mineral resource estimates at the Golden Eagle, Shearers, All Nations, Bartons, Otways and Little Wonder deposits. Construction of the Nullagine project began in July 2011 and by mid-November 65 per cent of the plant site earthworks had been completed. The works included clearing, top soil stockpiling and cut-to-fill preparation of the foundations for the elution tanks area, the mill, and the primary crusher areas. Permitting and design work for a 1.5 million tonne per annum carbon in leach processing facility and associated infrastructure, plus construction of a process water dam, had also been completed and a site road access upgrade had begun.
Millennium has purchased 95 per cent of the equipment required for the project, including a semi-autogenous grinding mill, primary crusher and gravity concentrator.
