Ngokwengxelo yeendaba yomhla wesi-8 kweyeNkanga ngo-2021, i-United States Geological Survey (USGS) ihlolisise iintlobo zezimbiwa ngokwe-Energy Act ka-2020, ezathi zachongwa njengeminerali ebalulekileyo ngo-2018. Kuluhlu olutsha olupapashweyo, kucetyiswa ezi ntlobo zilandelayo ze-ore ezingama-50 (ngolandelelwano lwealfabhethi).
I-Aluminiyam, i-antimony, i-arsenic, i-barite, i-beryllium, i-bismuth, i-cerium, i-cesium, i-chromium, i-cobalt, i-chromium, i-erbium, i-europium, i-fluorite, i-gadolinium, i-gallium, i-germanium, i-graphite, i-hafnium, i-holmium, i-runum, i-lithium magnesium, i-lithium magnesium, i-lithium magnesium, i-lithium manganese, i-lithium magnesium, i-idium, i-lithium, i-lithium, i-fluorite neodymium, nickel, niobium, palladium, platinum, praseodymium, rhodium, rubidium, lutetium, samarium, scandium, tantalum, tellurium, terbium, thulium, tin, titanium, tungsten, vanadium, ytterbium, yttrium, zinc,
Kwi-Energy Act, izimbiwa ezibalulekileyo zichazwa njengezimbiwa ezingezizo amafutha okanye izinto zezimbiwa ezibalulekileyo kuqoqosho okanye kukhuseleko lwase-US. Zithathwa njengezinto ezibuthathaka zokubonelela, iSebe leMicimbi yezeKhaya kufuneka lihlaziye imeko ubuncinci rhoqo emva kweminyaka emithathu ngokusekelwe kwindlela entsha yoMthetho weMizi-mveliso. I-USGS icela izimvo zoluntu phakathi komhla wesi-9 kweyeNkanga ukuya kowesi-9 kweyeDisemba, ngo-2021.
