A blockbuster quarter for this ASX miner. So, why aren’t investors impressed?

The Metals X Ltd (ASX: MLX) share price is edging lower today, despite the miner releasing a closely watched December quarter update.

At the time of writing, the Metals X share price is down 2.17% to $1.262.

That pullback comes after an extraordinary run. Metals X shares are still up roughly 175% over the past 12 months, helped by surging metal prices and a sharp turnaround at its core tin operations.

A record quarter at Renison

The key update came from the Renison tin operation in Tasmania, which Metals X owns 50% of through its joint venture with Bluestone Mines.

Renison delivered its second-highest quarterly production on record, producing 3,319 tonnes of tin-in-concentrate. That was a 46% increase from the prior quarter and comfortably above recent run rates.

December was particularly strong, with monthly production of 1,318 tonnes, the highest ever achieved at the site. The company credited higher mining rates, improved plant stability, and stronger metallurgical performance.

Mill recovery improved to 82% for the quarter, up from 76% previously, placing the December month among the strongest metallurgical periods on record.

Cash flow jumps as costs fall

Higher production and better recoveries translated into a sharp improvement in financial performance.

C1 cash production costs fell to $16,598 per tonne, a 28% improvement on the prior quarter. All-in sustaining costs (AISC) also dropped to $27,906 per tonne.

Imputed EBITDA more than doubled quarter-on-quarter to $112.5 million, with EBITDA margins rising to around 58%.

Metals X generated an imputed net cash flow of $19.48 million for the quarter. Cash and cash equivalents increased by $14.1 million to $293.6 million, even after continued investment across its broader portfolio.

More than just tin

Beyond Renison, Metals X continues to progress its growth options.

At the Rentails project, the company completed the draft environmental impact statement, with regulatory submissions expected in the March quarter. The concentrator FEED package has now been awarded, keeping the project on track for a final investment decision later in 2026.

Metals X also maintained its strategic investments, including holdings in Elements Ltd, First Tin, NICO Resources, and Tanami Gold. Management said capital allocation remains focused on disciplined growth and value-accretive opportunities.

Why the share price slipped today

Despite the strong numbers, today’s move likely reflects profit-taking after a huge run, rather than disappointment with the quarter.

With Metals X shares up 175% year-on-year, expectations were already high. Some investors may also be cautious after such an outstanding December result, especially with tin prices remaining volatile.

Still, this update reinforces that Metals X is generating serious cash in a favourable commodities backdrop.
