Reserves update at 31 December 2025: attributable recoverable reserves fell 7.6% to 850Mt (from 920Mt) and marketable reserves 5.9% to 640Mt. Resources unchanged at 4,400Mt. Continues the reserve decline already flagged as an open thread.
Reserves and resources fell at 31 December 2024. Attributable resources are 4,400Mt (down 9.4% from 4,857Mt), recoverable reserves 920Mt (down 5.2%) and marketable reserves 680Mt (down 5.6%). Continues the reserve decline thread.
Year-end 2022 attributable coal resources fell 13.5% to 5,201Mt from 6,013Mt, recoverable reserves fell 13.0% to 989Mt from 1,137Mt, and marketable reserves fell 22.8% to 731Mt from 819Mt. The statement notes no life-of-mine plans were completed in 2022.
Year-end 2021 attributable coal resources fell 12.7% to 6,013Mt (from 6,884Mt). Recoverable reserves slipped 1.5% to 1,137Mt and marketable reserves 1.7% to 819Mt. Austar is no longer reported following its move to closure.
Attributable coal resources rose to 6,911Mt from 6,442Mt, while recoverable reserves fell to 1,196Mt (1,240Mt in 2018) and marketable reserves to 872Mt (892Mt). Resources grew; reserves slipped, consistent with a year of mining depletion (inference).
Hong Kong version of the 2018 coal resources and reserves statement: attributable resources 6,442Mt, recoverable reserves 1,240Mt, marketable reserves 891Mt. Duplicate of the ASX release.
Year-end 2018 coal statement: attributable resources 6,442Mt, recoverable reserves 1,240Mt and marketable reserves 891Mt, after depletion by production. Covers the enlarged asset base including Hunter Valley Operations and Mount Thorley Warkworth; no prior-year totals appear in the text provided.
The 51:49 Hunter Valley Operations joint venture with Glencore completed. Glencore bought a 16.6% interest from Yancoal for about US$429m (subject to adjustments) and 32.4% from Mitsubishi, leaving Yancoal with 51%. Resolves a thread open since July 2017.
End-2017 attributable coal resources are 6,396Mt, recoverable reserves 1,304Mt and marketable reserves 923Mt, up from 2,879Mt, 555Mt and 402Mt a year earlier. The rise follows the Coal & Allied acquisition (its resources are as at end-2016).
Yancoal agreed a 51:49 Hunter Valley Operations joint venture with Glencore, which pays US$1,139m for 49%: US$710m to Mitsubishi and US$429m to Yancoal. Glencore replaces Yancoal's Mitsubishi tag-along and will take up to US$300m of any entitlement offer shortfall. Conditional on Coal & Allied completing.
Mitsubishi accepted the US$710m offer for its 32.4% of HVO JV. It also granted Yancoal a call option over its 28.9% of Warkworth for US$230m and exclusive agency for thermal sales to Japanese utilities. Conditional on Coal & Allied completing.
Year-end 2016 attributable resources are 2,879Mt, with recoverable reserves of 555Mt and marketable reserves of 402Mt. Annual JORC statement; excludes the proposed Coal & Allied assets.
Yancoal released its JORC-compliant coal resource and reserve statements for the year to December 2014, covering Ashton, Austar, Moolarben, Middlemount, Yarrabee, Donaldson and the Gloucester Basin. The visible text contains no tonnage figures, so the changes are not stated here.
Annual coal resource and reserve statements for December 2013, reported under the JORC Code. The extract does not show the totals, so any change from the February 2013 figures (3,824Mt resources, 799.7Mt reserves) cannot be confirmed. Some projects will move to the 2012 Code during 2014.
Revised JORC resources total 3,824Mt and reserves 799.7Mt, down 1.7% from 813.9Mt in the scheme booklet. Changes are described as minor. Moolarben resources rose 38Mt to 1,222Mt; Donaldson fell 58Mt to 827Mt.
