Why did PPTA's operating expenses surge in Q3 2024?

Perpetua Resources Corp. (NASDAQ:PPTA) did not report a surge in operating expenses in Q3 2024. In fact, the company reported a decrease in net loss to $2.9 million in Q1 2024, largely due to an increase in grant income to $5.2 million. The company's financial developments indicate a positive trend rather than a surge in operating expenses.
