Hudbay Minerals (TSX: HBM; NYSE: HBM) yabowola mchere wa mkuwa wa sulfide ndi oxide wapamwamba kwambiri pa projekiti yake yapafupi ndi pamwamba ya Copper World, mtunda wa makilomita 7 kuchokera ku projekiti ya Rosemont ku Arizona.Kubowola chaka chino kudazindikira madipoziti atatu atsopano, zomwe zidapangitsa kuti ma depositi asanu ndi awiri onse awonongeke pa 7-km projekitiyo.
Ma depositi atatu atsopanowa amatchedwa Bolsa, South Limb ndi North Limb.
Bolsa anabweza mphambano zitatu: mamita 80 a 1% zamkuwa, mamita 62.5 a 1.39% zamkuwa, ndi mamita 123 a 1.5% zamkuwa;zonse ndi mineralization kuyambira pamwamba.Gawo lazinthu za oxide likhoza kukhala loyenera kuchira kwa leach.Palinso kuthekera kopitilira kudutsa kusiyana kwa mita 1,500 pakati pa ma depositi a Bolsa ndi Rosemont.
Miyendo ya Kumpoto ndi Kumwera inabwezanso njira zina zitatu: mamita 32 pa 0.69% yamkuwa, mamita 23.5 pa 0.88% yamkuwa, ndi mamita 38 a 1.34% yamkuwa.Zonsezi zimachitika pamtunda kapena pafupi ndi skarn pakulumikizana pakati pa porphyry intrusive ndi mayunitsi a miyala yamchere.
Kubowola pa gawo la Copper World kunatsimikizira zotsatira zoyambirira, kubwezera mamita 82 a 0.69% zamkuwa (kuyambira pamtunda), kuphatikizapo mamita 74.5 a 1% zamkuwa;74.5 mamita a 0.62% yamkuwa, kuphatikizapo mamita 35 a 0.94% yamkuwa;ndi mamita 88.4 a 0.75% yamkuwa, kuphatikizapo mamita 48.8 pa 1.15% yamkuwa.
Mabowo awiri adakumbidwanso pa cholinga cha Broad Top Butte, kubwezera mamita 229 pa 0.6% yamkuwa, kuphatikizapo mamita 137 pa 0.72%;ndi mamita 192 a 0.48% yamkuwa, kuphatikizapo mamita 67 pa 0.77% yamkuwa.Mabowo onsewa adakumana ndi mineralization pamtunda.Copper oxides ndi sulphides anapezeka mu quartz-monzonite porphyry intrusive ndi m'ma skarn ozungulira mu malo ofanana a geological monga Rosemont.
Zotsatira zolimbikitsa
"Pulogalamu yathu ya 2021 yobowola ku Copper World yatsimikizira kuti ndalama zomwe zidapezeka kale zidakhalabe zotsegukira, ndipo tili olimbikitsidwa ndi kuzindikirika kwa ma depositi atatu atsopano mderali," atero a Peter Kukielski, Purezidenti ndi CEO wa Hudbay."Copper World ikukula kukhala pulojekiti yokongola yachitukuko chamkuwa pamapaipi athu achilengedwe, ndipo tikuyembekezerabe kuyerekeza kwazinthu zomwe zidaperekedwa kumapeto kwa chaka komanso kuwunika koyambirira kwachuma mu theka loyamba la 2022."
Gawo lachitukuko la ntchito ya Rosemont layeza ndi kusonyeza chuma chokwana matani 536.2 miliyoni omwe ali ndi 0.29% yamkuwa, 0.011% molybdenum ndi 2.65 g/t siliva.Zomwe zimaganiziridwa ndi matani 62.3 miliyoni omwe ali ndi 0.3% yamkuwa, 0.01% molybdenum ndi 1.58 g/t siliva.
