Sino Iron Pty Ltd v Mineralogy Pty Ltd [No 15]

The case Sino Iron Pty Ltd v Mineralogy Pty Ltd [No 15] involves a dispute between two parties, Sino Iron Pty Ltd (the plaintiffs) and Mineralogy Pty Ltd (the first defendant), concerning the continuation of a magnetite project in the Pilbara region. The plaintiffs sought additional tenure areas over statutory mining leases and general purpose leases held by the first defendant for the continuation of their established magnetite project. The dispute arose due to the first defendant's refusal to sign or submit a draft Mine Continuation Proposal (MCP) as a Co-Proponent, as required by the State Agreement, and its rejection of the plaintiffs' request for extra tenure areas without additional consideration.

The legal issues before the court included whether the plaintiffs were entitled to mandatory final injunctive orders to compel the first defendant to join with them in submitting MCPs to the Minister for approval, and whether the plaintiffs could obtain conditional orders to compel the first defendant to agree to grant the requested extra tenure areas. The court also considered additional causes of action raised by the plaintiffs, including conventional estoppel, estoppel by representation, and statutory unconscionable conduct by the first defendant. The case further examined the repercussions of the plaintiffs' late pre-trial amendments, which reduced the scale of their additional tenure claims and the scope of the extra tenure areas demanded from the first defendant.

The court found that the plaintiffs' request for additional tenure areas, as revised in the late pre-trial amendments, was reasonable in the circumstances. The court also determined that the plaintiffs were entitled to the mandatory final injunctive orders to compel the first defendant to join with them in submitting the MCPs to the Minister for approval. However, the court did not grant the conditional orders sought by the plaintiffs, as they were contingent on the Commonwealth Treasurer providing a notification and no action advice under the Foreign Acquisition and Takeover Act 1975 (Cth). The court found that the first defendant had not engaged in unconscionable conduct, and therefore, the plaintiffs' claims for estoppel and statutory unconscionable conduct were dismissed.
