Rio Tinto (RIO LN) 4815.5, Mkt cap £82.1bn – Oyu Tolgoi schedule delayed for additional technical studies • Rio Tinto has reported that its plans for the underground development of the Oyu Tolgoi copper project in Mongolia have been delayed by between 16 to 30 months while it investigates its options in response to “stability risks identified with the approved mine design”. • A number of options are under consideration some of which “may result in some of the critical infrastructure, such as the mid-access drive and ore handling system, being relocated or removed.” • The company says that “All options under consideration present a pathway to sustainable first production, and have different cost and schedule implications … … Preliminary estimates for development capital spend for the Project, depending on the outcome of the work described above, is now $6.5 billion to $7.2 billion, an increase of $1.2 billion to $1.9 billion from the $5.3 billion previously disclosed”. • In a company presentation in October 2016, Rio Tinto described how the addition of the large scale underground block caving operation to the existing open-pit operation at Oyu Tolgoi was expected to produce an average of 560,000tpa of copper between 2025-2030 at costs within the lowest quartile. The incorporation of the 495mt (Measured & Indicated) Hugo North orebody at an average grade of 1.26% copper and 0.35g/t gold and inferred orebodies at the Hugo South and Heruga deposits was expected to offer “a potential multi-decade future”. Conclusion: Although there may be some disappointment at the delay and possibility of increased cost of the Oyu Tolgoi underground operation, in the context of a large-scale, multi-decade operation, a delay of up to 30 months in the initial production in order to minimise operational risks and help ensure the smooth operation of the underground mine appears to be a prudent use of resources which we hope will avoid disruption over the long term life of the operation.

Mining group Rio Tinto has warned that capital costs at its Oyu Tolgoi copper mine in Mongolia have risen from an original estimate of $5.3bn to between $6.5bn-$7.2bn, with production delayed by up to 30 months. Separately, the company is maintaining its full-year iron ore exports forecast of between 320-330 million tonnes, despite first-half production at its Pilbara mine in Australia falling by 8% due to the effects of Cyclone Veronica and a fire at its Cape Lambert port facility.

Rio Tinto Plc (RIO.L) Announced, in its second quarter production results, that Pilbara iron ore shipments of 85.4 million tonnes (100% basis) in the second quarter were 3% lower than the second quarter of 2018. Shipments were impacted in April due to recovery works following Tropical Cyclone Veronica. 2019 guidance for Pilbara shipments was revised on 19 June 2019 to between 320 and 330 million tonnes, 100% basis (previously between 333 and 343 million tonnes) due to mine operational challenges. Unit cost guidance has been revised to $14 - $15 per tonne (previously $13 - $14 per tonne). Lower iron ore production was the primary driver of a 2% reduction in copper equivalent production in the first half compared to the corresponding period of 2018. Aluminium production of 0.8 million tonnes was in line with the second quarter of 2018. Mined copper production of 137 thousand tonnes was 13% lower than the second quarter of 2018, with lower production from Escondida and Kennecott reflective of lower grades. Second quarter production at Iron Ore Company of Canada was significantly higher than the corresponding quarter of 2018. Separately, the company announced that the Oyu Tolgoi underground project ('the Project') in Mongolia continued to progress in 2019 towards its path to become one of the largest copper mines in the world. Since February, key below ground infrastructure such as the control room facility and the jaw crusher system are now complete and construction of shafts 3 and 4 is progressing well. The commissioning of shaft 2 remains on track for October 2019. All options under consideration present a pathway to sustainable first production and have different cost and schedule implications. Meanwhile, the company announced that it has completed the sale of its entire interest in the Rössing uranium mine in Namibia to China National Uranium Corporation Limited (CNUC) for an initial cash payment of $6.5 million plus a contingent payment of up to $100 million.
