I-Newcrest Mining yenze inkqubela phambili entsha ekuphononongeni iprojekthi yeRed Chris eBritish Columbia, eKhanada kunye neprojekthi yaseHavieron eNtshona Ostreliya.
Le nkampani ibike into entsha efunyenweyo kwindawo yokuhlola izinto e-East Ridge kwiimitha ezingama-300 empuma ye-East Zone yeprojekthi yeRedcris.
I-drill yedayimani ibona iimitha ezili-198 kubunzulu beemitha ezingama-800. Udidi lwegolide yi-0.89 g/ton kwaye udidi lobhedu yi-0.83%, kuquka nobukhulu obuziimitha ezingama-76, udidi lwegolide yi-1.8 g/ton kunye nolwe-copper yi-1.5%. Umzimba we-ore ujikeleze zonke iindlela. Akukho nanye kuzo engene ngaphakathi.
Ukugrumba kwibhanti yasempuma nako kubone ukumbiwa kwegolide okukumgangatho ophezulu, okuqinisekisa ulwandiso olusezantsi lokumbiwa kwegolide. Kubunzulu beemitha ezingama-528, i-ore yi-524 yeemitha, umgangatho wegolide yi-0.37 g/ton, ubhedu yi-0.39%, kuquka nobukhulu beemitha ezili-156, umgangatho wegolide yi-0.71 g/ton, ubhedu yi-0.59%, kunye nobukhulu beemitha ezili-10, umgangatho wegolide yi-1.5 g/ton kunye nomgangatho wegolide yi-0.88%.
Okwangoku, le projekthi inezixhobo zokugrumba ezi-6 ezisakhiwayo, eziza kwanda ziye kwi-8 kwikota ezayo.
Umqulu wokuqala wezixhobo zikaRedChris uza kugqitywa kule nyanga.
KwiPhondo lasePatterson, eNtshona Ostreliya, ukugrumba ngamandla uMgodi weGolide waseHaweilong weXinfeng Mining Company kufumaniseke ukuba kukho ukwenziwa kwezimbiwa okuphezulu. Iimeko ezithile zomgodi zezi zilandelayo:
◎ Iimitha ezingama-97 kubunzulu beemitha ezingama-500, igolide yebanga le-3.9 g/ton, ubhedu lwe-0.5%, kuquka nobukhulu beemitha ezili-15, igolide yebanga le-9.7 g/ton kunye nobhedu lwe-1.8%;
◎ Iimitha ezili-169.5 ze-ore zibonwe kubunzulu beemitha ezingama-711.5, umgangatho wegolide wawuyi-3.4 g/ton, ubhedu 0.33%, kuquka nobukhulu beemitha ezingama-58.9, umgangatho wegolide wawuyi-6.2 g/ton kunye nobhedu 0.23% ubumbi beminerali;
◎Kubunzulu obuziimitha ezingama-537, kwabonwa iimitha ezingama-79.3 ze-ore, kunye nodidi lwegolide oluyi-4.5 g/ton kunye nobhedu oluyi-1.4%; kuquka nobukhulu obuziimitha ezingama-41.7, udidi lwegolide oluyi-8.4 g/ton kunye nobhedu oluyi-2.6%;
◎ Iimitha ezili-109.4 ze-ore zibonwe kubunzulu beemitha ezingama-622, umgangatho wegolide wawuyi-5.9 g/ton, ubhedu 0.63%, kuquka nobukhulu beemitha ezingama-24, umgangatho wegolide wawuyi-17 g/ton kunye nobhedu oluyi-1.4% lwemineralization.
Umzimba wesinyithi awukangeni nzulu. Okwangoku, le projekthi iqikelela ukuba imithombo yegolide yi-3.4 yezigidi zee-ounces kwaye ubhedu yi-160,000 yeetoni.
