Kambani yeNewcrest Mining yafambira mberi pakutsvaga chirongwa cheRed Chris muBritish Columbia, Canada uye chirongwa cheHavieron muWestern Australia.
Kambani iyi yakashuma nezvekuwanikwa kutsva munzvimbo yekutsvaga zvinhu kuEast Ridge iri mamita mazana matatu kumabvazuva kweEast Zone yepurojekiti yeRedcris.
Chibooreso chedhaimani chinoona mamita 198 pakadzika kwemamita 800. Goridhe remhando ye0.89 g/ton uye goridhe remhando yemhangura iri 0.83%, kusanganisira ukobvu hwemamita 76, goridhe remhando ye1.8 g/ton uye goridhe remhando ye1.5% mineralization yemhangura. Muviri wedombo uri kumativi ese. Hapana kana chimwe chazvo chakapinzwa.
Kuchera gomba rekumabvazuva kwakaonawo goridhe repamusoro-soro richiwedzerwa, zvichiratidza kuti mineralization yacho yakawedzera kubva kumaodzanyemba. Pakadzika kwemamita 528, dombo iri rine mamita 524, goridhe repamusoro riri 0.37 g/ton, mhangura 0.39%, kusanganisira ukobvu hwemamita 156, goridhe repamusoro 0.71 g/ton, mhangura 0.59%, uye ukobvu hwemamita 10, goridhe repamusoro 1.5 g/ton uye 0.88% mineralization yemhangura.
Parizvino, chirongwa ichi chine migero mitanhatu yekuboorera iri kuvakwa, iyo ichawedzera kusvika pasere muchikamu chinotevera.
Bhuku rekutanga reRedChris richapedzwa mwedzi uno.
MuPatterson Province, Western Australia, kucherwa kwakawedzerwa kweHaweilong Gold Mine yeXinfeng Mining Company kwakawana kuchera kwemhando yepamusoro kwezvicherwa. Mamiriro chaiwo emugodhi ndeaya anotevera:
◎ Mamita 97 muhupamhi hwemamita 500, goridhe regiredhi 3.9 g/tani, mhangura 0.5%, kusanganisira ukobvu hwemamita 15, goridhe regiredhi 9.7 g/tani uye mhangura 1.8% mineralization;
◎ Mamita 169.5 esimbi akaonekwa pakadzika kwemamita 711.5, goridhe raive 3.4 g/ton, mhangura 0.33%, kusanganisira 58.9 metres ukobvu, goridhe raive 6.2 g/ton uye mhangura 0.23% mineralization;
◎Pakadzika kwemamita 537, 79.3 metres yesimbi yakaonekwa, ine goridhe re4.5 g/ton uye mhangura 1.4%; kusanganisira 41.7 metres ukobvu, goridhe re8.4 g/ton uye mhangura 2.6% mineralization;
◎ Mamita 109.4 esimbi akaonekwa pakadzika kwemamita 622, goridhe raive 5.9 g/ton, mhangura 0.63%, kusanganisira 24 metres ukobvu, goridhe raive 17 g/ton uye mhangura 1.4% mineralization.
Dumbu rematombo harina kupinda mukati. Parizvino, chirongwa ichi chinofungidzira kuti zviwanikwa zvegoridhe zvinosvika mamiriyoni 3.4 emaunzi uye mhangura inorema matani 160,000.
