E ai ki tētahi pūrongo a Bloomberg News i te 24 o Pēpuere, 2021, kei te whakaaro a Harmony Gold Mining Co. ki te whakanui ake i te hohonutanga o te keri i raro i te whenua i te maina koura hohonu rawa atu o te ao, e ai ki ngā kitenga a ngā kaihanga o Āwherika ki te Tonga, kua uaua haere te keri i ngā rahui konganuku e memeha haere ana.
I kī te Tumu Whakarae o Harmony, a Peter Steenkamp, ​​kei te rangahau te kamupene i te keri o ngā maina koura i Mponeng ki tua atu i te hohonutanga o nāianei e 4 kiromita, ka roa ake pea te roa o te maina mā te 20 ki te 30 tau. E whakapono ana ia he "nui" ngā rahui konganuku i raro i tēnei hohonutanga, ā, kei te tūhuratia e Harmony ngā tikanga me te haumitanga e hiahiatia ana hei whakawhanake i ēnei putunga.
Ko Harmony Gold Mining Company tētahi o ngā kaihanga koura torutoru e toe ana i Āwherika ki te Tonga i pēhi i ngā hua mai i ngā rawa tawhito. I tautokona e African Rainbow Minerals Ltd., he apiti o te pirionaire mangu a Patrice Motsepe, i te tau kua hipa. I hokona e rātou te Mboneng Gold Mine me ōna rawa mai i AngloGold Ashanti Ltd., ā, ko rātou te kaihanga koura nui rawa atu i Āwherika ki te Tonga.
I te Tūrei, i pānuitia e Harmony kua piki ake tana hua i te haurua tuatahi o te tau neke atu i te toru ngā wā. Ko te whāinga a te kamupene he pupuri i te putanga ā-tau o te Mboneng Gold Mine ki te 250,000 auneke (7 tāne), ka āwhina pea tēnei ki te pupuri i te putanga katoa o te kamupene ki te 1.6 miriona auneke (45.36 tāne). Heoi, i te piki haere o te hohonutanga o te keri, kei te piki haere hoki te mōrearea o ngā rū whenua me te matenga o ngā kaimahi i mau i raro i te whenua. I kī te kamupene i waenganui i a Hune me Tīhema o te tau kua hipa, e ono ngā kaimahi i mate i roto i ngā aituā keri i te wā e mahi ana te kamupene.
Ko te maina koura o te ao o Mboneng te maina hohonu rawa atu o te ao i tēnei wā, ā, ko tētahi o ngā maina koura nui rawa atu, teitei rawa atu hoki te kounga. Kei te taha raki-mā-uru o te Witwatersrand Basin i te Porowini o te Tai-mā-uru o Āwherika ki te Tonga te maina. He putunga koura-uranium tawhito momo-Rand. I te Hakihea 2019, ko te nui o ngā rahui koura kua whakamātauhia me ngā rahui pea o te Maina Koura o Mboneng he tata ki te 36.19 miriona tana, ko te kounga koura he 9.54g/t, ā, ko te nui o ngā rahui koura kei roto he tata ki te 11 miriona hekere (345 tana); Ko te Maina Koura o Mboneng i te tau 2019 Ko te nui o te koura i hangaia he 224,000 hekere (6.92 tana).
I mua, ko te umanga koura o Āwherika ki te Tonga te mea nui rawa atu o te ao, engari nā te pikinga o te utu mō te keri i ngā maina koura hohonu me te pikinga o ngā uauatanga whenua, kua iti haere te umanga koura o te whenua. Nā te nekenga o ngā kaihanga koura nui pērā i a Anglo Gold Mining Company me Gold Fields Ltd. ki ētahi atu maina whai hua i Āwherika, Ahitereiria me Amerika, e 91 tana koura i whakaputaina e te umanga koura o Āwherika ki te Tonga i te tau kua hipa, ā, i tēnei wā he 93,000 noa iho āna kaimahi.
