The S&P/ASX 200 Index (ASX: XJO) is out of form on Tuesday. In afternoon trade, the benchmark index is down 0.25% to 7,998.8 points.
Four ASX shares that are falling more than most today are listed below. Here's why they are dropping:
Champion Iron Ltd (ASX: CIA)
The Champion Iron share price is down 2% to $6.33. This morning, this Canadian iron ore miner announced a gradual return of its workforce to its Bloom Lake mine following a preventive evacuation and temporary shutdown of operations in response to nearby forest fires. However, it also advised that the timing and resumption of full operational activities remain subject to the availability of railway services. Management continues to collaborate with local authorities and the railway operator to expedite a return to normal operations, while prioritising the safety of its employees and the community.
Core Lithium Ltd (ASX: CXO)
The Core Lithium share price is down 4% to 11.5 cents. This is despite there being no news out of the lithium miner today. However, it is worth noting that its shares have been on fire in recent sessions. This could mean that some investors are taking some profit off the table on Tuesday after a weak night for lithium stocks on Wall Street. Even after this decline, Core Lithium's shares are up 25% since this time last week. Though, it is worth remembering that they remain down over 85% on a 12-month basis.
Encounter Resources Ltd (ASX: ENR)
The Encounter Resources share price is down 13% to 72 cents. This follows the release of initial assays from first pass, wide-spaced aircore drilling at the Green target of the Aileron project. While the drilling has mapped out carbonatite hosted niobium-REE mineralisation over 1.6km of strike (which remains open), it seems that some investors were betting on stronger results. Nevertheless, its executive chairman, Will Robinson, was pleased. He said: "Broad spaced aircore drilling is achieving what we had hoped by rapidly identifying and mapping out near surface mineralised carbonatites in the West Arunta. The mineralised trend at Green broadly follows a curved, magnetic anomaly extending to the north-east from WA1's Luni discovery and wraps around into the Stromness fault."
Rio Tinto Ltd (ASX: RIO)
The Rio Tinto share price is down 2.5% to $117.09. Investors have been selling the mining giant's shares after it fell short of expectations during the second quarter. The consensus estimate for iron ore shipments was 82Mt, but Rio Tinto reported shipments of 80.3Mt. It was the same for copper production, which came in at 171kt compared to the consensus estimate of 175kt. Management now expects to hit the low end of its copper guidance for the full year.
