去年4月，該公司獲準(zhǔn)將年選礦量上限提高至4萬噸左右，并恢復(fù)在格蘭維爾東部露天礦場的開采。作為協(xié)議的一部分，該公司被要求建立一個新的尾礦儲存設(shè)施。在此過程中，選礦廠的材料將從尾礦和庫存材料過渡到格蘭維爾東部礦山的更高礦石。
據(jù)首席執(zhí)行官彼得·威廉姆斯稱，這一里程碑標(biāo)志著向二級運(yùn)營(Level 2 operations)的過渡。據(jù)說該公司“對第一個區(qū)塊的品位特別滿意”，這是“更典型的地下礦山”，而不是礦山的露天開采方式。
國際錫協(xié)觀點(diǎn):向二級運(yùn)營的過渡預(yù)計將導(dǎo)致錫精礦產(chǎn)量增加至每年550噸左右，這將提供必要的現(xiàn)金流，幫助支撐該公司的其他開發(fā)項(xiàng)目，其中包括塔隆加(Taronga)錫項(xiàng)目。塔隆加項(xiàng)目目前正處于規(guī)劃階段，該公司正使該項(xiàng)目朝著采礦作業(yè)計劃前進(jìn)，隨后將進(jìn)行大約5萬噸礦石的初步采礦。
