On July 12, 2012, Aquila completed the sale of its 50% joint venture interest in Isaac Plains to Ocean Coal Mining, a wholly owned subsidiary of Sumitomo Corporation.

Eagle Downs’ first cluster of gas drainage wells were completed in the 100 series longwall area, consisting of nine vertical wells and nine horizontal holes covering three seams and four monitoring holes.

The well infrastructure was nearly completed in the quarter and pre-work to establish the drainage systems has commenced.

Pumping has started on the holes to remove water prior to initiating the gas drainage.

The holes will be used to understand the Eagle Downs gas reservoir characteristics and assist the design of the gas drainage program.

The quality drilling program which involved large diameter holes in the target seams to confirm the coal coking properties is complete.

Construction of staff housing is nearly complete.

The concrete arch sections have been delivered to site in preparation for the establishment of the drift portals.

Construction of the site powerlink substation continued and the construction of the site access road was completed.

The sealed road, which includes a security point and carpark, is approximately 6km long and provides all weather access to the site.

The site construction office was completed.
