Newcrest Mining e entse kgatelopele e ntjha ho batlisiseng projeke ya Red Chris mane British Columbia, Canada le projeke ya Havieron mane Australia Bophirima.
Khamphani e tlalehile ka tšibollo e ncha sebakeng sa ho batla lirafshoa sa East Ridge se limithara tse 300 ka bochabela ho Sebaka se ka Bochabela sa projeke ea Redcris.
Borokho ba taemane bo bona limithara tse 198 botebong ba limithara tse 800. Sehlopha sa khauta ke 0.89 g/ton mme sehlopha sa koporo ke 0.83%, ho kenyeletsoa le botenya ba limithara tse 76, sehlopha sa khauta ke 1.8 g/ton le koporo ke 1.5%. 'Mele oa lejoe o ka mahlakoreng 'ohle. Ha ho le e 'ngoe ea tsona e ileng ea kenella.
Ho cheka lebanta le ka bochabela ho boetse ho bone ho ba le diminerale tsa kgauta tsa maemo a hodimo, ho tiisa katoloso e ka borwa ya ho ba le diminerale. Botebong ba dimithara tse 528, lejwe ke dimithara tse 524, boleng ba kgauta ke 0.37 g/ton, koporo 0.39%, ho kenyeletswa le botenya ba dimithara tse 156, boleng ba kgauta ke 0.71 g/ton, koporo 0.59%, le botenya ba dimithara tse 10, boleng ba kgauta ke 1.5 g/ton le 0.88% ya boleng ba koporo.
Hajoale, projeke ena e na le didiriswa tse 6 tsa ho tjheka tse ntseng di hahuwa, tse tla eketseha ho fihla ho tse 8 kotara e tlang.
Bolumo ea pele ea mohloli oa RedChris e tla phethoa khoeling ena.
Profenseng ea Patterson, Australia Bophirima, ho cheka ka matla Morafo oa Khauta oa Haweilong oa Khamphani ea Merafo ea Xinfeng ho fumane ho eketsoa ha liminerale tsa boleng bo holimo. Maemo a tobileng a morafo ke a latelang:
◎ Dimithara tse 97 botebong ba dimithara tse 500, kgauta ya sehlopha sa 3.9 g/ton, koporo ya 0.5%, ho kenyeletswa le botenya ba dimithara tse 15, kgauta ya sehlopha sa 9.7 g/ton le koporo ya 1.8% ya diminerale;
◎ Methara tse 169.5 tsa ore li bonoe botebong ba limithara tse 711.5, boleng ba khauta e ne e le 3.4 g/ton, koporo e ne e le 0.33%, ho kenyeletsoa le botenya ba limithara tse 58.9, boleng ba khauta e ne e le 6.2 g/ton le koporo e nang le mineralization ea 0.23%;
◎Botebong ba limithara tse 537, ho bonoe dimetara tse 79.3 tsa lejwe la bohlokwa, ka boleng ba kgauta ba 4.5 g/ton le koporo ya 1.4%; ho kenyeletswa le botenya ba dimetara tse 41.7, boleng ba kgauta ya 8.4 g/ton le boleng ba minerale ya koporo ya 2.6%;
◎ Methara e 109.4 ea lera e bonoe botebong ba limithara tse 622, boleng ba khauta e ne e le 5.9 g/ton, koporo e ne e le 0.63%, ho kenyeletsoa le botenya ba limithara tse 24, boleng ba khauta e ne e le 17 g/ton le boleng ba koporo e le 1.4%.
'Mele oa tšepe ha o so kene botebong. Hona joale, projeke e hakanya hore mehloli ea khauta ke li-ounces tse limilione tse 3.4 'me koporo ke lithane tse 160,000.
