SolGold tshaj tawm $ 20m nrhiav nyiaj txiag rau Alpala tshawb nrhiav
Ecuador-focused miner SolGold (LON, TSX:SOLG) tab tom pib nrhiav nyiaj txiag los nce qhov tsawg kawg nkaus ntawm £ 16 lab (kwv yees $ 20m).
Lub tuam txhab hais tias kev nrhiav nyiaj txiag nrhiav kom them tag nrho cov nqi ntawm kev tshawb fawb ua ntej (PFS) rau Alpala tooj liab-kub qhov project, ib feem ntawm SolGold's Cascabel cuab tam.
Qhov kev txav mus los, txawm li cas los xij, los ntawm cov neeg ua haujlwm sab saum toj sim ua kom zoo dua ntawm kev lag luam thoob ntiaj teb kev poob qis los ntawm tus kabmob coronavirus, nthuav lawv cov ntaub ntawv los ntawm kev sib koom ua ke thiab kev yuav khoom.
"Cov nyiaj no tseem yuav them rau cov nqi ntawm SolGold cov kev tshawb fawb tseem ceeb hauv cheeb tsam thiab cov nqi ntxiv ntawm kev tsim cov pob nyiaj tsim tawm $ 2.7 billion rau Alpala project," tus thawj coj Nick Mather tau hais hauv cov lus hais t.
SolGold tso rau hnub Thursday yuav luag 75 lab sib koom, ntawm 21.5 pence apiece, txog rau tag kis, Lub Rau Hli 5 thaum 7:00 sawv ntxov GMT.
Nws ua raws li daim ntawv cog lus muaj nuj nqis nyiaj txiag nrog streaming tuam txhab Franco Nevada (TSX, NYSE: FNV), inked nyob rau lub Tsib Hlis . Qhov kev pom zoo tau lav SolGold $ 100 lab thiab muab nws txoj kev xaiv kom nce mus txog $ 150 lab.
Qhov ntawd yog ntau npaum li cas cov miner xav tau rau PFS ntawm Alpala, ib feem ntawm Cascabel cuab tam, nyob 180 km sab qaum teb ntawm lub nroog Quito.
Lub tuam txhab, lub hom phiaj tseem ceeb ntawm lub hom phiaj vim yog lub peev xwm ntawm nws txoj haujlwm tsis tau tsim nyob rau hauv South American lub teb chaws, tau hais tias nws xav kom xa daim ntawv tshaj tawm rau lub caij nplooj zeeg 2020.
SolGold kuj tau hais tias nws yuav siv cov nyiaj los tsim cov kev tshawb fawb txog qhov ua tau zoo ntawm cov cuab tam, yuav tsum tau tso tawm hauv lub quarter thib ob ntawm 2021.
Australian miner tau tham nrog ntau tus tub ua lag luam txij li lub Peb Hlis, vam tias yuav tau txais $ 2.85 billion los tsim Alpala . Raws li qhov kev hloov kho tshiab tshaj plaws , cov cuab tam muaj 2.66 billion tonnes ntawm tooj liab ntawm 0.53% tooj liab sib npaug hauv cov ntsuas thiab qhia pawg, thiab 544 lab tonnes ntawm 0.31% tooj liab sib npaug hauv pawg inferred.
Ib zaug tsim, Alpala xav tias yuav tsim tau qhov nruab nrab ntawm 150,000 tonnes ntawm tooj liab, 245,000 ounces kub thiab 913,000 ounces ntawm cov nyiaj nyob rau hauv mloog nyob rau hauv ib xyoos thaum nws 55-xyoo lub neej-ntawm-mine.
Nyob rau thawj 25 xyoo ntawm kev tsim cov mining, qhov nruab nrab txhua xyoo yuav tsum yog 207,000 tonnes ntawm tooj liab, 438,000 ounces kub thiab 1.4 lab ooj nyiaj.
Txawm hais tias muaj kev cuam tshuam me me vim muaj kev cuam tshuam txog tus kabmob coronavirus, SolGold lub hom phiaj pib tsim khoom hauv 2025.
Mather tau hais ntau zaus tias nws pab neeg tab tom tsim lub tuam txhab "tseem ceeb rau kev txhim kho Ecuador li BHP yog rau Australia."
BHP, Newcrest tsis txaus siab
SolGold cov tswv lag luam loj tshaj plaws, BHP thiab Newcrest, tau tshaj tawm rau pej xeem kom cov thawj coj ntawm lub tuam txhab me kom nce nyiaj los ntawm kev ncaj ncees. Lawv sib cav tias txoj hauv kev yog qhov zoo tshaj plaws ntawm cov tswv cuab tam sim no.
BHP (ASX: BHP), the world’s No. 1 mining company, and Newcrest Mining (ASX: NCM), Australia’s largest gold producer, were not pleased with SolGold’s decision last month to BHP ( ASX No. 12%.
Newcrest, tooj liab junior tus thib ob loj tshaj investor nrog 15.23% paj, txawm txiav txim siab tshem tawm nws tus neeg sawv cev ntawm SolGold lub rooj tsavxwm.
Thaum qhov kev nrhiav nyiaj txiag xav tsis thoob tshaj tawm hnub no zoo li ua raws li BHP thiab Newcrest qhov kev cia siab, ob leeg yuav tsis koom nrog kev txhawj xeeb txog SolGold txoj hauv kev rau nyiaj txiag.
"Newcrest yuav tsis koom nrog kev loj hlob. Peb poob siab rau txoj hauv kev uas Solgold tswj hwm tau ua raws li kev muab nyiaj txiag rau lub tuam txhab, "said Newcrest tus cev lus hais rau Australia's Financial Review.
BHP thiab Newcrest 'ua ke 30% ceg txheem ntseeg hauv SolGold yuav zoo li txo qis los ntawm kev sib tw hauv kev nrhiav nyiaj txiag, uas Ecuador-focused miner tau hais tias tsim ib lub sijhawm los "txhim kho lub tuam txhab cov tswv cuab hauv paus los ntawm kev qhia cov tub ua lag luam tshiab."
Tooj liab kub qhov chaw
Ob xyoos dhau los, Ecuador tau nyiam qhov kev txaus siab los ntawm cov neeg ua haujlwm loj loj nrhiav kom lawv raug tooj liab. Cov hlau ua tau zoo heev yog nyob rau hauv kev thov rau kev siv lub zog tauj dua tshiab thiab lub tsheb hluav taws xob, tab sis loj, cov nyiaj tso tawm tshiab tsis tshua muaj.
Copper nkag mus rau hauv lub khw muag nyuj rau hnub Thursday , txhawb nqa los ntawm kev thov muaj zog los ntawm Tuam Tshoj tom qab kaw thiab cov nyiaj tiv thaiv kaw cov nyiaj poob qis.
Nws tau ua lag luam ntau dua 20% los ntawm nws lub Peb Hlis qis ntawm $ 4,371 ib tonne rau hnub Thursday tav su, ntawm $ 5,530 ib tonne. Qhov kev nce no haum rau lub ntsiab txhais ntawm lub khw muag nyuj.
Diversified majors tshwj xeeb tshaj yog nyiam cov haujlwm loj, lub neej ntev, xws li SolGold cog lus. BHP nce nws cov ceg txheem ntseeg hauv lub tuam txhab xyoo tas los mus rau 15.31% los ntawm 14.7%, dhau los ua tus tswv lag luam sab saum toj.
Ecuador lub hom phiaj yuav txav los ntawm qhov chaw tshawb nrhiav hotspot mus rau tus xa tawm tsuas . Nws txoj kev lag luam roj tau raug cuam tshuam rau ob peb lub hlis dhau los.
Lub tebchaws tam sim no rov qab los ntawm ob qho tib si kis ntawm covid-19 thiab kev tawg ntawm cov nqi roj thoob ntiaj teb.
Ua ntej kev txhim kho tsis ntev los no, South American lub teb chaws xav tias yuav nyiam $ 3.7 nphom hauv kev nqis peev hauv mining ntawm 2019 thiab 2020, nce ntau ntawm $ 270 lab nws tau txais hauv 2018.
Pob Zeb Zeb Liner Khoom Xaiv
Cov khoom sib txawv crushed, txawv kev ua haujlwm xav tau cov ntaub ntawv sib txawv kom haum. Tsis tas li ntawd, cov ntxhib sib tsoo compartment thiab nplua sib tsoo compartment xav tau cov ntaub ntawv sib txawv.
H&G Machinery muab cov khoom hauv qab no los nrum koj lub pob zeb liner:
Manganese hlau
Cov ntsiab lus ntawm cov manganese steel pob zeb hauv ob sab phlu yog feem ntau 11-14%, thiab cov ntsiab lus carbon feem ntau yog 0.90-1.50%, feem ntau yog siab dua 1.0%. Ntawm qhov cuam tshuam qis, qhov hardness tuaj yeem ncav cuag HB300-400. Thaum muaj kev cuam tshuam loj, lub hardness tuaj yeem ncav cuag HB500-800. Nyob ntawm qhov cuam tshuam, qhov tob ntawm txheej txheej hardened tuaj yeem ncav cuag 10-20mm. Lub hardened txheej nrog siab hardness tuaj yeem tiv thaiv kev cuam tshuam thiab txo qis hnav. High manganese steel muaj kev ua tau zoo los tiv thaiv kev hnav zoo nyob rau hauv cov xwm txheej ntawm kev cuam tshuam zoo abrasive hnav, yog li nws feem ntau siv rau hauv qhov hnav-tiv taus ntawm cov mining, cov khoom siv, thermal zog, thiab lwm yam khoom siv kho tshuab. Nyob rau hauv cov xwm txheej uas tsis tshua muaj kev cuam tshuam, siab manganese hlau tsis tuaj yeem ua rau cov yam ntxwv ntawm cov khoom siv vim tias kev ua haujlwm hardening tsis pom tseeb.

Chrome Alloy hlau
Chromium alloy cam khwb cia hlau muab faib ua high chromium alloy cam khwb cia hlau (chromium ntsiab lus 8-26% carbon ntsiab lus 2.0-3.6%), nruab nrab chromium alloy cam khwb cia hlau (chromium ntsiab lus 4-6%, carbon ntsiab lus 2.0-3.2%), tsawg chromium Peb hom alloy cam khwb cia hlau (chromium ntsiab lus 1-3%, cov ntsiab lus carbon 2.1-3.6%). Nws qhov zoo tshaj plaws feature yog hais tias lub microhardness ntawm M7C3 eutectic carbide yog HV1300-1800, uas yog faib nyob rau hauv daim ntawv ntawm ib tug tawg network thiab cais nyob rau hauv lub martensite (lub hardest qauv nyob rau hauv cov hlau matrix) matrix, txo cov cleavage nyhuv ntawm matrix. Yog li ntawd, high-chromium alloy liner muaj lub zog siab, pob zeb toughness, thiab siab hnav tsis kam, thiab nws qhov kev ua tau zoo sawv cev rau qib siab tshaj plaws ntawm cov khoom siv hlau tam sim no.
