Kev tshawb pom tshiab ua nyob rau hauv qub tooj liab mine hauv Northern Cape Province, South Africa
Lub Tuam Txhab South African Copper 360 (Copper360) tau tshawb pom tshiab hauv thaj chaw qub tooj liab mining hauv Northern Cape Province ntawm lub tebchaws.
Qhov kev tshawb pom tshiab tau ua nyob ze cov mines qub ntawm Tweefontein. Lub tuam txhab pab pawg geological tau tshawb pom ib qho 1.5-kilometer-ntev magnetic anomaly cheeb tsam los ntawm kev soj ntsuam drone magnetic, suav nrog plaub qhov sib txawv ntawm tooj liab anomalies.
Surface sampling tau lees paub tias qib tooj liab ntawm thawj thaj chaw txawv txav txawv ntawm 2.12% mus rau 17.47%.
Kev ua raws li kev tshawb fawb tau lees paub tias qhov tsis txaus ntseeg muaj qhov bandwidth ntawm 4-8 meters thiab qhov tob tob ntawm 50 meters yam tsis muaj kev nkag mus. Lub ntsiab ore tej yam kev mob yog: 5.8 meters tuab, tooj liab qib 2.71%; 13 meters tuab, tooj liab qib 4.69%.
Kev txiav txim los ntawm cov ntaub ntawv geological tam sim no, thaj chaw tsis zoo no txuas ntxiv 500 meters raws li kev tawm tsam, thiab lub cev tooj liab tuaj yeem yog qhov tshiab tooj liab.
"Qhov saum npoo ntawm cov ore yog ze li ntawm 35 meters, nrog rau qib tooj liab ntawm 4.5%. Cov ore yog loj heev, thiab kev tshawb nrhiav geophysical qhia tau hais tias muaj ntau txheej txheej ntawm ore lub cev. Qhov tseem ceeb tam sim no yog tias peb tuaj yeem muaj cov tooj liab zoo ib yam. rau Chile's nyob rau sab qaum teb Cape thawj zaug, uas zoo ib yam li Chile's Piv nrog cov mines tooj liab nrog ib qib ntawm tsuas yog 0.25%, cov qib ntawm cov pob zeb qhib loj loj ntawm peb li yog nyob nruab nrab ntawm 2.5% thiab 4.5%, "said lub tuam txhab CEO Jan Nelson. Lub tuam txhab ntseeg tias lub cev ore tsis tau nkag mus rau hauv qhov tob, thiab txij li tsuas yog ua haujlwm saum npoo tau ua tiav, qhov ntsuas ntawm qhov kev tshawb pom no tsis yog me me. Nyob rau tib lub sijhawm, qhov drilling tseem tsis tau pib hauv thaj chaw sib sib zog nqus thiab hauv peb thaj chaw tsis sib xws, uas yog qhov loj dua li thawj thaj tsam anomaly. Yog tias peb qhov kev tsis sib haum xeeb ua rau tib yam tshwm sim, qhov kev tshawb pom tshiab tuaj yeem muab piv rau qhov loj me rau Chilean tooj liab mine.
Copper360 tau mus rau pej xeem thaum lub Plaub Hlis xyoo tas los thiab tau txais cov cuab tam xws li Rietberg tooj liab mine los ntawm kev nrhiav tau ntawm Okiep Copper Company. Los ntawm 1937 txog 1950, Rietberg Copper Mine mined 138,700 tons ntawm ore nrog qib tooj liab ntawm 25.4%, ua rau nws qib siab tshaj plaws tooj liab mined hauv cheeb tsam.
Tam sim no, Ritterberg tag nrho cov peev txheej tau nce los ntawm 25,275 tons hauv 2022 txog 81,200 tons, nce ntawm 220%, ntawm cov peev txheej inferred yog 60,800 tons.
