Queensland Industrial Minerals Pty Ltd v Younger; Queensland Industrial Minerals Pty Ltd v Ryan

In this case, Queensland Industrial Minerals Pty Ltd (QIML) sought a declaration that it was entitled to mine over certain land belonging to Younger and Ryan. The landholders argued that QIML was not entitled to mine over their land without paying compensation. The dispute was heard in the Queensland Supreme Court. The key legal issues before the court were whether the landholders were entitled to compensation for the impact of the mining on their properties, and if so, the quantum of that compensation. The court had to consider whether a 15-year mining lease constituted a loss in perpetuity, whether a Net Present Value calculation should be accepted, and if so, whether that calculation should be adjusted for various contingencies. The court also had to decide whether a discount rate of 3.5% was appropriate and whether an amount claimed for accommodation costs during the term of the mining lease was doubling up.

The court held that the landholders were entitled to compensation for the impact of the mining on their properties, but not for the full amount claimed. The court found that the mining lease did not amount to a loss in perpetuity and that the Net Present Value calculation should be accepted as the best method of assessing the landholders' loss. However, the court held that the calculation should be adjusted to account for various contingencies, including the risk of the mine being flooded, the risk of the mine being abandoned, and the risk of the mine not being as profitable as anticipated. The court also held that the discount rate of 3.5% was appropriate and that the amount claimed for accommodation costs during the term of the mining lease was not doubling up. The court found that the landholders were entitled to compensation for the loss of access to the flood margin land during the term of the mining lease, but not for uncertainty about resuming access to the flood margin land when the mining lease ends.

The court made a declaration that QIML was entitled to mine over the land, but only on the condition that it paid compensation to the landholders. The exact amount of compensation was not specified in the judgment, but the court held that it should be calculated on the basis set out in the judgment. The court also held that the landholders were entitled to compensation for the loss of access to the flood margin land during the term of the mining lease, but not for uncertainty about resuming access to the flood margin land when the mining lease ends. The court did not make any orders regarding the landholders' claim for compensation for the impact of the mining on their properties other than to declare that they were entitled to compensation.
