Sandfire Resources Ltd (ASX:SFR) saw its stock price soar 5.24% during intraday trading on Tuesday, following the release of its fiscal third-quarter results. The mining company reported significant improvements in both revenue and production, boosting investor confidence.

According to the company's latest filing, Sandfire achieved unaudited group sales revenue of AU$283 million for Q3 FY25, a substantial increase from AU$206 million in the same period last year. The underlying earnings before interest, taxes, depreciation, and amortization (EBITDA) also showed impressive growth, reaching AU$145 million compared to AU$93 million in the previous year.

The positive financial performance was underpinned by increased production across key metals. Copper output rose to 25,490 tonnes, up from 25,013 tonnes a year earlier. Zinc production saw a significant jump to 21,532 tonnes from 18,526 tonnes, while silver production increased to 1.1 million ounces from 900,000 ounces. Despite a slight decrease in lead production, the overall production figures remained strong. Sandfire has maintained its group copper-equivalent production guidance of 154,000 tonnes for fiscal 2025, further reinforcing investor optimism. While the company did increase its cost guidance for the Matsa copper operations in Spain by 4%, the robust production and revenue figures appear to have outweighed this concern in the eyes of investors.
