Still, Lundin described the sinkhole as stable and pushed back against suggestions that the change in size was cause for alarm. The media reports of the sinkhole materially increasing in size are inaccurate. On July 30, the sinkhole measured approximately 32 meters in diameter at the surface, 48 meters in diameter at the bottom and 64 meters deep, spokesman Mark Turner said on Monday. Turner said the diameter at the bottom of the sinkhole was 48 metres, while the diameter at the top was approximately 36.5 meters. He said that the expansion of the surface was caused by small amounts of material dropping from the walls. Turner said that the measured depth has been reduced to approximately 62 metres.
Two days after the sinkhole was discovered, Lundin said it had suspended development work at the mine. Turner said the company shut down the underground mine shortly after due to safety concerns. On August 4, Chile's National Service of Geology and Mining, which is investigating the sinkhole and vows to come up with updates later this week, ordered the mine to shut down, which Lundin said it had already done. More On This Topic The sinkhole developed near Lundin's Ojos del Salado operation in Chile's Atacama region, 20 kilometres south of the city of Copiap The operation contains two underground mines Santos and Alcaparrosa and is part of Lundin's Candelaria mining complex.
The complex is expected to produce between 155,000 and 165,000 tons of the metal in 2022, or about 60 per cent of Lundin's total copper output. The closure of the Alcaparrosa mine isn't likely to affect Lundin's annual guidance for the Candelaria mining complex, as it contributes about five per cent of the total ore processed annually by the complex. Turner said that information on the sinkhole was shared with community leaders, community members, and other stakeholders. On August 2, Lundin Mining's shares fell to $6.71, its lowest in a year, after the company confirmed the existence of a sinkhole near the mine. The company closed at $6.95 on Monday, up 10 cents or 1.46 per cent, within a 52 week trading range of $6.57 and $14.
