Ngomhla we-15 kweyeDwarha, iqela lesithathu lengxelo yokusebenza kwemveliso yeToppi ngo-2021. Ngokwengxelo, kwiqela lesithathu lika-201, indawo yemigodi yaseRio Tinto ePilbara ithumele iitoni zesinyithi ezingama-83.4 ezigidi, ukonyuka kwe-9% ukusuka kwinyanga ephelileyo kunye nokunyuka kwe-2% kwisibini. I-Rio Tinto ibonise kwingxelo ukuba ngenxa yempembelelo yolawulo lwama-freckles, iiprojekthi zokutshintshwa kwamandla e-brownfield kunye nokulibaziseka kwexesha lama-202, inani lezehlo zesinyithi kwimigodi yasePilbara kwisigaba sesithathu yayiziibhiliyoni ezingama-833, kunye nokuhla okuhle kwe-4% kunye nokunyuka kwe-10% inyanga nenyanga.
Ukongeza, ngenxa yeRio Tinto, ngenxa yemvakalelo eNtshona Ostreliya, iKuddedley Valley Brownfield Project kunye neLobo River Green Brownfield Capacity Replacement Project ziye zalibaziseka kancinci. Umsebenzi wokuthunyelwa kwesinyithi kwindawo yemigodi yasePilbara eCanada ngo-2021 uza kuba yi-320 yezigidi zeetoni. Iitoni ~ 320 yezigidi zeetoni. Injongo yeebriquettes zesinyithi zaseKhanada kunye neebriquettes zesinyithi ezicolekileyo ngexesha elinye zifikelela kwiitoni ezingama-950 ukuya kwi-1050 zeetoni (cinga ngeetoni ezili-1050 ukuya kwi-1200 zeetoni).
