Brazil regulator orders partial halt at Sigma Lithium mine over 'imminent risk'
SGML•Brazil's mining regulator ordered a partial halt at Sigma Lithium's Grota do Cirilo mine, citing an unspecified “imminent risk” and requiring immediate corrective work on a section of the north pit's eastern slope.
1. Partial mining halt
Brazil's mining regulator ANM ordered Sigma Lithium to halt mining activities in part of its Grota do Cirilo mine, citing an unspecified “imminent risk.” The agency ordered immediate corrective work on a “ruptured section” of the north pit's eastern slope, and said the area will remain closed until the work is complete.
2. Additional risk measures
ANM also demanded measures to mitigate risks at the mine and said it “will take appropriate measures in the event of non-compliance.” The effect of the stoppage on Sigma's mining activities is unclear; the company had already been affected by the recent suspension of its environmental licenses and an interdiction on its waste piles.
