去年4月，該公司獲準(zhǔn)將年選礦量上限提高至4萬(wàn)噸左右，并恢復(fù)在格蘭維爾東部露天礦場(chǎng)的開(kāi)采。作為協(xié)議的一部分，該公司被要求建立一個(gè)新的尾礦儲(chǔ)存設(shè)施。在此過(guò)程中，選礦廠的材料將從尾礦和庫(kù)存材料過(guò)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(jí)運(yùn)營(yíng)(Level 2 operations)的過(guò)渡。據(jù)說(shuō)該公司“對(duì)第一個(gè)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(kāi)采方式。
國(guó)際錫協(xié)觀點(diǎn):向二級(jí)運(yùn)營(yíng)的過(guò)渡預(yù)計(jì)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(kāi)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(jì)劃前進(jìn)，隨后將進(jìn)行大約5萬(wàn)噸礦石的初步采礦。
