I-Hudbay Minerals (TSX: HBM; NYSE: HBM) ibhoboze i-copper sulfide ne-oxide mineralization yezinga eliphezulu kakhulu kuphrojekthi yayo eseduze nomhlaba we-Copper World, amakhilomitha ayi-7 ukusuka kuphrojekthi ye-Rosemont e-Arizona.Ukumba kulo nyaka kuhlonze amadiphozithi amasha amathathu, okwenza isamba semali efakiwe ayisikhombisa esitelekeni esingamakhilomitha ayi-7 kulo msebenzi.
Amadiphozithi amathathu amasha abizwa nge-Bolsa, i-South Limb kanye ne-North Limb.
I-Bolsa ibuyise izimpambanomgwaqo ezintathu: amamitha angu-80 ethusi elingu-1, amamitha angu-62.5 ethusi elingu-1.39%, namamitha angu-123 ethusi elingu-1.5%;konke ngokugaywa kwamaminerali kuqala phezulu.Ingxenye yezinto ze-oxide ingase ifaneleke ukutholwa kwe-leach.Kuphinde kube namandla okuqhubeka kulo lonke igebe lamamitha angu-1,500 phakathi kwediphozithi ye-Bolsa ne-Rosemont.
I-North and South Limbs ibuyise ezinye izimpambanomgwaqo ezintathu: amamitha angama-32 ku-0.69% yethusi, amamitha angama-23.5 ku-0.88% yethusi, namamitha angama-38 ethusi elingu-1.34%.Kokubili kwenzeka endaweni noma eduze kwayo ku-skarn ekuxhumaneni phakathi kwamayunithi e-porphyry intrusive kanye ne-limestone.
Ukubhoboza idiphozithi ye-Copper World kuqinisekisile imiphumela yangaphambili, ukubuyisela amamitha angu-82 we-0.69% yethusi (kusukela phezulu), kuhlanganise namamitha angu-74.5 we-1% yethusi;74.5 amamitha 0.62% yethusi, kuhlanganise 35 amamitha 0.94% yethusi;kanye namamitha angu-88.4 ethusi elingu-0.75%, kuhlanganise namamitha angu-48.8 ku-1.15% yethusi.
Kuphinde kwabhojwa imigodi emibili endaweni okuhloswe ukuthi iBroad Top Butte, kwabuyiselwa amamitha angama-229 ku-0.6% yethusi, okuhlanganisa namamitha ayi-137 ku-0.72%;kanye namamitha angu-192 ethusi elingu-0.48%, kuhlanganise namamitha angu-67 ku-0.77% yethusi.Zombili izimbobo zihlangabezane nokumbiwa phansi.Ama-oxide e-Copper nama-sulphide atholwe ku-quartz-monzonite porphyry intrusive kanye nasezikhiqizweni ezizungezile endaweni efana ne-geological efana ne-Rosemont.
Imiphumela iyakhuthaza
“Uhlelo lwethu lokuzivivinya lwango-2021 eCopper World lubonise ukuthi imali egciniwe etholakale ngaphambilini ihlale ivuliwe ngesikhathi sesiteleka, futhi sikhuthazwa kakhulu ukuhlonzwa kwamadiphozithi amasha amathathu endaweni,” kusho uPeter Kukielski, umongameli kanye ne-CEO ka-Hudbay."I-Copper World ikhula ibe iphrojekthi ekhangayo yokuthuthukiswa kwekhopha kumzila wethu wezinto eziphilayo, futhi sisasendleleni yokuthola isilinganiso sokuqala sensiza ngaphambi kokuphela konyaka kanye nokuhlolwa komnotho kokuqala engxenyeni yokuqala ka-2022."
Isigaba sokuthuthuka iphrojekthi ye-Rosemont ilinganise futhi yabonisa izinsiza ezenza amathani ayizigidi ezingu-536.2 ezisezingeni elingu-0.29% lethusi, 0.011% molybdenum kanye nesiliva elingu-2.65 g/t.Insiza ecatshangelwayo ingamathani ayizigidi ezingama-62.3 afaka ithusi elingu-0.3%, i-0.01% molybdenum kanye nesiliva elingu-1.58 g/t.
