The strong profitability and deleveraging signal a fundamental turnaround, but the negative working capital and going concern disclosure warrant caution. Monitor the collection of the $22 million accounts receivable and the receipt of the $50 million advance payment from the new offtake agreement by end of June 2026, which should significantly improve liquidity. The successful mining ramp-up to 240,000 tonnes annualized production is the key catalyst to watch for sustained cash flow generation.
