Brief process info 2020
- Oyu Tolgoi delivered a strong safety performance as evidenced by an AIFR of 0.22 per 200,000 hours worked for the six months ended June 30, 2020.
- Despite the unprecedented challenges posed by the COVID-19 pandemic, the Oyu Tolgoi open pit has continued to operate uninterrupted.
- In 2020, Oyu Tolgoi produced 36,495 tonnes of copper and 31,150 ounces of gold.
- Copper production remains on track to achieve guidance of 140,000 to 170,000 tonnes.
- Gold production guidance for 2020 has increased to 155,000 – 180,000 ounces from 120,000 – 150,000 ounces. The increase in gold production guidance is due to a change in the open pit schedule which has brought forward higher-grade gold ore from the southwest pit.
- C1 cost guidance range is being lowered to $1.60 - $2.00 from $1.80 - $2.20 per pound of copper due to the positive impact from the increased 2020 gold production forecast.
- Work on the Oyu Tolgoi underground continued, achieving strong productivity in underground advancement during 2020 achieving 1,8302 equivalent metres (eqm) in June and a monthly average of 1,8312 eqm for the quarter.
- During 2020, underground development spend was $242.4 million, resulting in total project spend since January 1, 2016 of approximately $4.0 billion.
- Routine Shaft 2 rope shortening was successfully completed in May with remote presence technology from the vendor being used to assist onsite teams to safely perform the task. Payload and speeds have returned to planned levels and people and materials movement via the service hoist continue to operate normally.
- Shafts 3 and 4 continued on care and maintenance during 2020, and this is expected to continue until expert service providers can return to site to complete technical commissioning of specialized equipment and commence sinking activities. Work also slowed on some essential underground material handling infrastructure, in particular the construction of primary crusher one, which has now returned to 24-hour shifts following a period of day shift only. Personnel numbers on site have been limited in order to manage the risks around COVID-19.
