Integra Underground is 100% Glencore owned.
On 18 December 2015, HV Coking Coal Pty Limited (HVCC) (a 100% Glencore-owned company) purchased the Integra Complex.
Summary:
The Integra Underground Project Area is predominantly covered by shallow hillslope-based colluvium, with alluvial based sedimentary deposits in the valley floors. These are in turn sequentially underlain by coal measures of the Vane Subgroup, Archerfield Sandstone and Jerrys Plains Subgroup of the Whittingham Coal Measures. The sequence contains interlayered sandstone, conglomerate, mudstone, siltstone and coal.
Summary:
Underground mining operations are approved at a maximum extraction rate of 4.5 million tonnes per annum (Mtpa) of run-of-mine (ROM) coal until 31 December 2035 under PA 08_0101. This approval allows longwall mining of the Hebden, Barrett and Middle Liddell seams to produce high quality, semi-hard coking coal for export.
Integra Underground completed secondary extraction of Longwall 16 in April 2021 and commenced mining Longwall 17 in May 2021. Development of first workings in 2021 continued in Longwall 17, Longwall 18, and Longwall 19.

Summary:
PA 08_0101 (as modified) allows for the extraction, processing, and transportation of up to 4.5 Mtpa until 31 December 2035.
All ROM coal was stockpiled by Integra Underground before being hauled by Bloomfield operations
along their internal haul roads to Rix’s Creek North (owned by Bloomfield) CHPP for processing.
