2012 Integrated Development and Operations Plan Technical Report

The 2012 IDOP Technical Report, was prepared for Turquoise Hill Resources in March 2012, based on the technical, production and cost information contained in the OT LLC study titled Integrated Development and Operations Plan (IDOP). IDOP was completed by the Rio Tinto PLC appointed management of OT LLC in March 2011 as the basis for the proposed project financing.

IDOP used only Measured and Indicated Mineral Resources and is a complete study of all aspects of the Project. The IDOP Technical Report analyzes a reserve case only and is based on a pre-feasibility quality level study complying with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects, although some parts of the Oyu Tolgoi Project are further advanced and are at feasibility level. The IDOP Technical Report meets the standards of US SEC Industry Guide 7 requirements for reporting Mineral Reserves.

The analysis in the 2012 IDOP Technical Report has been called the IDOP Reserve Case in order to distinguish it from the cases in previous studies of Oyu Tolgoi. IDOP is an update of the previous comprehensive project study Integrated Development Plan 2010.
