15Km east of Wandoan, Queensland
Target Coal:
44.6Mt Indicated & Inferred (Thorn Hill Deposit) according to JORC guidelines


The East Wandoan Project comprises three granted permits. The granted permits are EPC 1955 covering 124 sub-blocks, EPC 2237 comprising 138 sub-blocks and EPC 1987 covering 115 sub-blocks.

The area occurs in a strip which trends in a South Easterly direction, approximately 25km northeast of Wandoan town, which is 400km northwest of Brisbane. The area is gently undulating and largely open with some remnant patches of native vegetation.  Shown in the diagram below is a cross section for the Thorn Hill Deposit located in the southern end of EPC 1955.

The Thorn Hill Deposit has a total coal resource of 44.6Mt, identified in its 2012 drilling campaign (22.1Mt in the Indicated Resource category, and 22.5Mt in the Inferred Resource category).


Over the period June-October 2011, Cuesta carried out a 17 open hole, 3 core hole program in the southern corner of EPC 1955 immediately to the north of the Bottle Tree Deposit held by Cockatoo Coal. All holes were geophysically logged and core samples were sent away for analysis and an Inferred JORC resource of 23.9Mt was announced by the Company on 6th of February 2011.  In March/April 2012 Cuesta completed 39 holes for a total of 59 holes drilled in the southern section of EPC 1955. The drilling has resulted in the delineation of 44.6Mt (22.1Mt Indicated, 22.5Mt Inferred) of resource calculated in accordance with JORC guidelines and is now referred to as the Thorn Hill Deposit.


Exploration of the Surat Basin commenced in the late 1960s by major companies including Exoil Limited, Shell, Griffin Coal and MIM/Xstrata Coal. Historic early exploration work identified the following first order coal deposits:

  • Wandoan Coal Deposits (>1,000 Mt) currently owned by Xstrata Coal;
  • Collingwood Deposit (229 Mt) recently acquired from Anglo American by Cockatoo Coal Limited.

A combination of historic poor coal prices and lack of infrastructure in the region hindered the development of the above coal deposits. Recent increased coal demand and prices reactivated strong interest in the region targeting lesser explored coal areas with immediate success.   Inferred and Indicated Mineral Resources defined adjacent to the Cuesta Coal tenements include:

  • Bottle Tree Deposit (~36Mt) currently owned by Cockatoo Coal Limited
  • The Range Deposit (~290Mt) currently owned by Stanmore Coal Limited.

This affords Cuesta Coal an opportunity on these EPCs to identify significant shallow thermal coal deposits.
