MinRes Shares Drop 12% in March as Range Takes Shape

Mineral Resources shares (ASX:MIN) have pulled back sharply through March, falling back into a consolidation range despite record earnings as broader market volatility and commodity uncertainty weigh on sentiment.

MinRes shares closed 3.7% lower at A$53.61 on the final trading day of March, capping a difficult month that saw the stock decline 12.09%. The pullback has pushed shares into negative territory on a year-to-date basis, down 3.3%, despite a remarkable 123.65% rally over the past twelve months. The shares have twice attempted to break through the A$60 level in recent weeks, only to be rejected each time, establishing a clear trading range between A$50 and A$60 that has characterised much of 2026 to date. At current levels, MinRes sits roughly 20% below its 52-week high of A$65.79, yet remains firmly above the A$14 low touched just twelve months ago.

The March selloff comes as the broader ASX materials sector has taken a hammering through the month, as oil prices surged and Middle East conflict escalated. Mining companies proved especially vulnerable during these sessions, with markets questioning the sustainability of commodity demand amid signs of slowing global growth and persistent China economic concerns.

Fundamentals Remain Strong

The current weakness stands in stark contrast to the operational momentum MinRes demonstrated just weeks ago. On 24 February, the company reported record first-half earnings driven primarily by the successful ramp-up of its flagship Onslow Iron project. The market initially cheered the result, sending shares nearly 5% higher on the day as the numbers confirmed that MinRes was successfully transitioning from a primarily lithium-focused story to a more balanced iron ore, mining services and lithium portfolio.

Onslow Iron has emerged as the centrepiece of MinRes’s growth strategy, with quarter-on-quarter iron ore shipment growth from the project offsetting modest volume declines at the company’s Pilbara Hub operations. The project’s contribution to the record half-year result validated the substantial capital investment and execution risk MinRes undertook to bring the asset online. On 18 March, the company announced another milestone with first ore loaded onto ship from its Lamb Creek iron ore project in the Pilbara Hub, further expanding its iron ore production footprint and demonstrating continued execution across its project pipeline.

Yet markets have proven unwilling to reward this operational progress in light of wider geopolitics. The disconnect also reflects the view of some in the analyst community, as Macquarie maintained an Underperform rating on the stock even as iron ore shipment volumes climbed, citing concerns over valuation, capital intensity and commodity price risk. These institutional views create natural resistance at higher price levels, with sell-side models acting as gravitational pull when shares approach the A$60-65 zone.

What Next For MinRes?

While the company’s Wodgina joint venture with Albemarle represents a Tier-1 lithium asset with long-term structural demand support from electrification trends, lithium prices have proven volatile over the past eighteen months. The sector experienced periods of exuberance followed by sharp corrections as supply caught up with demand, and any softness in lithium quickly feeds through to MinRes’s share price.

From a technical analysis perspective, MinRes appears to be consolidating after its impressive rally, with the A$50-60 range representing a battle between profit-takers and longer-term accumulation. Bulls view the current setup as healthy digestion, allowing earnings growth to catch up with the share price appreciation and establishing a higher structural trading band than earlier levels. From this perspective, macro-driven weakness without company-specific deterioration represents an opportunity to add exposure at more attractive levels within the range.

Bears counter that extended macro uncertainty, potential further weakness in iron ore or lithium prices, and the company’s high capital expenditure and debt load warrant caution. The combination of elevated geopolitical risk, oil price volatility and questions over China’s economic trajectory creates a challenging backdrop for highly cyclical, capital-intensive resource companies. Multiple large projects in various stages of ramp-up also introduce execution risk that could disappoint if operational challenges emerge or commodity prices soften from current levels.

Whether the current A$50-60 range represents consolidation before the next leg higher or a ceiling will be known in time. Quarterly production updates, Chinese economic data releases and any material shifts in iron ore or lithium spot prices will all influence sentiment in MinRes from here.
