Wyloo snaps up remaining Greatland stake

Rio Tinto (ASX: RIO) has reported its iron ore port operations have resumed after Tropical Cyclone Narelle passed over WA’s Pilbara region. Port closures at Rio’s four Pilbara iron ore port terminals commenced on March 24 and ship loading at East Intercourse Island, Parker Point and Cape Lambert B recommenced on March 28. Damage to Cape Lambert A is currently being repaired and shipping at that facility is expected to recommence in the coming days. Recent weather events, including Tropical Cyclone Mitchell in February, are estimated to have impacted iron ore shipments by about 8mt, however, the company has identified a pathway to recover about half of these losses. Rio’s Pilbara iron ore shipment guidance for 2026 remains unchanged at 323-338mt. 

Rio Tinto’s (ASX: RIO) Diavik diamond mine in the Northwest Territories of Canada has seen its final day of production after 23 years of operation.The mine which has produced more than 150 million carats of rough diamonds was discovered in 1991 beneath Lac de Gras, 220km south of the Arctic Circle.Mining began in 2003, utilising both open pit and underground mining methods to produce predominantly white gem quality diamonds and a small proportion of rare yellow diamonds.A celebration at the mine was attended by Indigenous Government Organisations, government representatives and other stakeholders to signal the formal completion of production.Diavik chief operating officer Matthew Breen says this milestone reflects the significance of the operation in the region.“Diavik has been an inspired collaboration between a modern mining company and Indigenous partners with an enduring legacy of socioeconomic benefits for the North” he said.“We look forward to continuing to respectfully reclaim the land in line with our commitments to, and in partnership with, the Government of the Northwest Territories and Indigenous partners.”Planning for closure has been underway since before production began, with closure objectives covering safety, land use, landforms, water and biodiversity and community capacity.Closure activities will extend to 2029, followed by a period of post-closure monitoring.Rio Tinto says the rough diamonds from the final production phase will be polished and sold through 2026 and beyond via its global customer network.

Lynas Rare Earths (ASX: LYC) recorded Q3 FY26 revenue of $265m, primarily driven by increasing prices and higher volume sales of both neodymium-praseodymium and total rare earth oxide products.The miner produces 1996t of neodymium-praseodymium, 8t of dysprosium and terbium and first production of samarium oxide in Q3.Lynas says it is closely monitoring its supply chains, including fuel supply and other raw materials affected by geopolitics and global fuel markets.“To date, we have not experienced any material disruptions due to the current global fuel supply situation,” Lynas said.“However, price increases are expected for a number of materials. It is difficult to forecast the magnitude and duration of these price increases. Our supply chain team is monitoring this closely and accelerating projects which should deliver greater efficiency.”Lynas has benefited from a reduction in diesel fuel requirements, following the full commissioning of the 65MW Mt Weld hybrid renewable power station in H1 FY26.Compared to Q3 FY25, when Mt Weld was operating a diesel power plant, the new power station has saved more than 870,000l of diesel, according to Lynas.

Liontown (ASX: LTR) lifted H1 revenue to $207.5m as the underground ramp-up at Kathleen Valley drove a 106% surge in sales volumes.Kathleen Valley’s 1mtpa run rate was delivered on schedule, with Liontown targeting 1.5mtpa by the end of March.Liontown managing director and chief executive Tony Ottaviano says Kathleen Valley is now a 100% underground operation.“We have delivered a 1mtpa underground run-rate on schedule, sold 190,000t of concentrate across ten shipments and more than doubled revenue period to period,” he said.“The underground ramp-up is on track and we expect the second half to be materially stronger as volumes, recoveries and pricing all continue to improve.”Kathleen Valley was still ramping up in H1 with AISC of $1,179/dmt weighing on margins, although Liontown expects unit costs and cash generation to improve in H2.The miner reported an average realised spodumene price of US$888/dmt, with an encouraging price signal for Liontown coming out of its November 2025 Metalshub spot auction, which cleared at US$1,254/dmt for shipment in January 2026.Liontown says spodumene prices were strengthening into CY26 and expects cash generation to improve in H2.“The balance sheet has been reset. Pro forma gearing (excluding leases) has dropped from 48% to 22% and we had $390m in cash at 31 December 2025,” Mr Ottaviano said.“This provides us with a strong financial foundation to complete the ramp-up, progress the 4mtpa expansion study and continue to grow the company to its full potential.“We are one of a small number of producers globally that can bring additional lithium tonnes to market quickly through brownfield expansion of an operating asset. The expansion study is underway and we are advancing critical path procurement now."Liontown posted a statutory net loss of $184m, including $104.4m loss on the LGES convertible note primarily driven by the company’s share price increasing from $.70 to $1.575 over the period.Liontown said the note converted to equity in February, with an estimated $58m gain expected to be recognised on conversion.
