I-Newcrest Mining yenze inqubekelaphambili entsha ekuhloleni iphrojekthi ye-Red Chris e-British Columbia, e-Canada kanye nephrojekthi ye-Havieron eNtshonalanga ye-Australia.
Le nkampani ibike ngokutholwa okusha endaweni yokubheka i-East Ridge engamamitha angama-300 empumalanga ye-East Zone yephrojekthi ye-Redcris.
I-drill yedayimane ibona amamitha angu-198 ekujuleni kwamamitha angu-800.Ibanga legolide liyi-0.89 g/ton kanti ibanga lethusi lingu-0.83%, okuhlanganisa ugqinsi lwamamitha angu-76, ibanga legolide elingu-1.8 g/ton kanye nethusi elingu-1.5%.Umzimba we-ore ukuzo zonke izinhlangothi.Akekho kubo owangena.
Ukumba ebhandeni elisempumalanga kuphinde kwabona ukumbiwa kwegolide okusezingeni eliphezulu, okuqinisekisa ukwandiswa kokumbiwa kwezimbiwa ngaseningizimu.Ekujuleni kwamamitha angu-528, insimbi ingamamitha angu-524, ibanga legolide lingu-0.37 g/ton, ithusi 0.39%, kuhlanganise nogqinsi lwamamitha angu-156, ibanga legolide lingu-0.71 g/ton, ithusi elingu-0.59%, nogqinsi lwamamitha angu-10, igolide ibanga elingu-1.5 g. /ton kanye ne-0.88% yokumbiwa phansi kwethusi.
Njengamanje, lo msebenzi unemishini yokumba eyi-6 esakhiwayo, ezonyuka ibe yi-8 kwikota elandelayo.
Ivolumu yokuqala yensiza yakwaRedChris izoqedwa kule nyanga.
EsiFundazweni sasePatterson, eNtshonalanga ye-Australia, ukumba okuqinisiwe kweMayini Yegolide yase-Haweilong ye-Xinfeng Mining Company kutholwe ukumbiwa kwezimbiwa okusezingeni eliphezulu.Imibandela ethile yemayini imi kanje:
◎ amamitha angu-97 ekujuleni kwamamitha angu-500, igolide grade 3.9 g/ton, ithusi 0.5%, kuhlanganise 15 metres ukujiya, igolide grade 9.7 g/ton kanye nethusi 1.8% mineralization;
◎ Amamitha angu-169.5 ensimbi abonwe ekujuleni okungamamitha angu-711.5, izinga legolide lalingu-3.4 g/ton, ithusi elingu-0.33%, kuhlanganise nogqinsi lwamamitha angu-58.9, igolide ibanga elingu-6.2 g/ton kanye nethusi elingu-0.23% lokugaywa kwamaminerali;
◎Ekujuleni okungamamitha angu-537, kwabonwa amamitha angu-79.3 ensimbi, izinga legolide elingu-4.5 g/ton kanye nethusi elingu-1.4%;okuhlanganisa ugqinsi lwamamitha angu-41.7, izinga legolide elingu-8.4 g/ton kanye nethusi elingu-2.6% lokumbiwa kwezimbiwa;
◎ Amamitha angu-109.4 ensimbi abonwe ekujuleni kwamamitha angu-622, izinga legolide lalingu-5.9 g/ton, ithusi lingu-0.63%, okuhlanganisa ugqinsi lwamamitha angu-24, igolide ibanga elingu-17 g/ton kanye nethusi elingu-1.4%.
Umzimba wensimbi awukangeni ujule.Njengamanje, iphrojekthi ilinganisela ukuthi izinsiza zegolide zingama-ounces ayizigidi ezingu-3.4 kanti ithusi lingamathani angu-160,000.
