Wahi a kahi hōʻike a Bloomberg News ma Pepeluali 24, 2021, ke noʻonoʻo nei ʻo Harmony Gold Mining Co. e hoʻonui hou aku i ka hohonu o ka hana ʻeli ʻana ma lalo o ka honua ma ka lua gula hohonu loa o ka honua, e like me ka ʻike ʻana o nā mea hana ma ʻApelika Hema, ua lilo ia i mea paʻakikī loa ke ʻeli ʻana i nā waihona ʻaila e emi ana.
Ua ʻōlelo ʻo Peter Steenkamp, ​​Luna Nui o Harmony, ke aʻo nei ka ʻoihana i ka hana ʻeli ʻana i nā lua gula ma Mponeng ma ʻō aku o ka hohonu o 4 kilomita o kēia manawa, kahi e hoʻolōʻihi ai i ke ola o ka lua i 20 a 30 mau makahiki. Manaʻoʻiʻo ʻo ia he "nui" nā waihona one ma lalo o kēia hohonu, a ke ʻimi nei ʻo Harmony i nā ʻano hana a me ka hoʻopukapuka kālā e pono ai e hoʻomohala i kēia mau waihona.
ʻO Harmony Gold Mining Company kekahi o nā mea hana gula i koe ma ʻApelika Hema i ʻohi i nā loaʻa kālā mai nā waiwai kahiko. Ua kākoʻo ʻia e African Rainbow Minerals Ltd., he lālā o ka piliona ʻeleʻele ʻo Patrice Motsepe, i ka makahiki i hala. Ua loaʻa iā ia ka Mboneng Gold Mine a me kāna waiwai mai AngloGold Ashanti Ltd., a lilo i mea hana gula nui loa ma ʻApelika Hema.
Ua hoʻolaha ʻo Harmony i ka Pōʻalua ua piʻi aʻe kāna loaʻa kālā ma ka hapa mua o ka makahiki ma mua o ʻekolu manawa. ʻO ka pahuhopu o ka hui, ʻo ia ka mālama ʻana i ka hana makahiki o ka Mboneng Gold Mine ma kahi o 250,000 auneke (7 tons), kahi e kōkua ai i ka mālama ʻana i ka hana holoʻokoʻa o ka hui ma kahi o 1.6 miliona auneke (45.36 tons). Eia naʻe, i ka piʻi ʻana o ka hohonu o ka hana ʻeli ʻana, ke piʻi nei hoʻi ka pilikia o nā hanana ōlaʻi a me ka make ʻana o nā limahana i paʻa i lalo o ka honua. Ua ʻōlelo ka hui ma waena o Iune a me Dekemaba i ka makahiki i hala, ua make ʻeono mau limahana i nā ulia kaʻa i ka wā o ka hana a ka hui.
ʻO ka lua gula papa honua ʻo Mboneng ka lua hohonu loa o ka honua i kēia manawa, a ʻo ia kekahi o nā lua gula nui loa a kiʻekiʻe loa. Aia ka lua ma ka ʻaoʻao komohana ʻākau o ke kahawai ʻo Witwatersrand ma ka Panalāʻau ʻĀkau Komohana o ʻApelika Hema. He waihona gula-uranium kahiko ʻano Rand ia. I Dekemaba 2019, ʻo ka nui o nā waihona ore i hōʻoia ʻia a hiki ke loaʻa o ka Mboneng Gold Mine ma kahi o 36.19 miliona tons, ʻo ke ʻano gula he 9.54g/t, a ʻo ka nui o nā waihona gula i loko ma kahi o 11 miliona auneke (345 tons); ʻO ka hana gula ʻo Mboneng Gold Mine i ka makahiki 2019 he 224,000 auneke (6.92 tons).
