The largest producer of lithium oxide concentrate in the Americas, Sigma Lithium Corporation, has reported record second-quarter financial results with an earnings before interest, taxes, depreciation and amortisation margin of 47% - the highest in the company's history and 39% higher compared with the first quarter.

The Canada-headquartered company generated net revenues of $55-million from the sale of 24 400 t of lithium oxide concentrate in the second quarter, having realised a 17% higher year-on-year price of $2 089/t.

This while gross and operating margins remained high at 60% and 32%, respectively, supported by decreased costs.

Sigma explains that that its plant gate cost decreased by 36% quarter-on-quarter to $401/t while cost, insurance and freight cost decreased by 33% quarter-on-quarter to $452/t. The company's all-in sustaining cost decreased by 6% quarter-on-quarter to $668/t, owing to upgraded mine operations resulting from financial discipline and from a 50% growth in production volumes.

Sigma has managed to decrease its total debt by 25% since the second quarter of last year and remains on track to increase production to 330 000 t/y in the 2027 financial year, compared with the current rate of 240 000 t/y.

The company is increasing its installed industrial capacity by building two additional plants, which will see production increase to 580 000 t/y by the end of 2027 and further to 830 000 t/y by the end of 2028.

Sigma owns and operates the Grota do Cirilo operation in Brazil, which is one of the world's largest lithium production sites - particularly the fifth-largest industrial/mineral complex for lithium oxide concentrate globally.
