Significant disruptions were caused by Tropical Cyclone Veronica, and a fire at our Cape Lambert A port in the first quarter. The impacts of the cyclone continued into the second quarter, with repairs to the Cape Lambert A port facilities impacting Robe Valley and Yandicoogina shipments and operations – Our Pilbara operations delivered an underlying Free On Board (FOB) EBITDA margin of 72%, compared with 67% in 2018 first half. – 2019 first half Pilbara unit cash costs were $14.6 per tonne (2018 first half: $13.4 per tonne). The fire and weather-related events reduced first half shipments by 14 million tonnes (100% basis), increasing unit costs by around $1.2 per tonne. – Gross sales revenue for our Pilbara operations included freight revenue of $0.6 billion (2018 first half: $0.8 billion). – We priced approximately 77% of our sales with reference to the current month average index; 16% with reference to the prior quarter’s average index lagged by one month; 5% with reference to the current quarter average; and 2% on the spot market – Approximately 33% of our sales were made on an FOB basis with the remainder sold including freight 35 ©2019, Rio Tinto, All Rights Reserved

A weaker pricing environment, in particular for primary metal, was the primary driver for the decline, reducing our underlying EBITDA by $0.8 billion compared with 2018 first half. This was partly offset by volume, mix and cost gains delivered through productivity improvements – Despite the pressures, we maintained our position as a leading business in the sector, with an EBITDA margin from integrated operations of 27% – The average realised price per tonne averaged $2,174 in H1 2019 (H1 2018: $2,547) – The cash LME price averaged $1,826 per tonne, 17% lower than 2018 first half, and the mid-West premium rose 6% to $420 per tonne – VAP represented 54% of the primary metal we sold (2018 first half: 58%) and generated attractive product premiums averaging $242 per tonne of VAP sold (2018 first half: $222 per tonne) aligned with our value over volume strategy – Although broadly balanced in alumina, approximately 2.2 million tonnes of our legacy alumina sales contracts are exposed to a fixed linkage to the LME price 36 ©2019, Rio Tinto, All Rights Reserved

The lower price impacts were offset by increased sales volumes of copper and lower costs linked to productivity improvements at our managed operations – We generated $0.8 billion in cash from our operating activities, an 8% decrease on 2018 first half. This included $315 million of dividends from Escondida, compared with $405 million received in 2018 first half – Free cash flow of $(90) million, reflected a 6% increase in net capital expenditure to $855 million, mainly relating to activities at the Oyu Tolgoi underground project – Average copper prices decreased 11% to 280 US cents per pound, and the average gold price declined 1% to $1,307 per ounce compared with 2018 first half. These price declines, together with weaker diamond pricing and provisional pricing movements, resulted in a $237 million decrease in underlying EBITDA 37 ©2019, Rio Tinto, All Rights Reserved

We also saw an improvement in operational performance at our titanium dioxide operations following the disruptions in 2018 first half – We generated net cash of $0.7 billion from our operating activities and $0.5 billion of free cash flow, reflecting the stronger pricing environment and the improved operational performance – On 26 November 2018, we announced that we had entered into a binding agreement with China National Uranium Corporation Limited for the sale of our entire 68.62% stake in Rössing Uranium.
