Lookout Hill West (100% Entrée) |
Lookout Hill West covers an area of approximately 49,272 hectares and includes the western portion of the Shivee Tolgoi mining licence (Shivee West) which is not subject to the Entrée-Ivanhoe Joint Venture and all of the Togoot mining licence.
Exploration of Lookout Hill West since 2002 has comprised satellite image interpretation, reconnaissance exploration, geophysical surveys (IP and airborne and ground magnetic), detailed geological mapping, rock sampling, conventional and MMI soil sampling, trenching, diamond and reverse-circulation drilling. This work identified and drill tested numerous prospective copper, gold, molybdenum and deep IP targets at Shivee West. In addition to metal targets, coal targets have been evaluated on the Togoot licence.
Shivee West
Shivee West includes areas geologically similar to the Devonian-aged setting of the Entree-Ivanhoe Mines joint venture deposits, Hugo North Extension and Heruga, and Ivanhoe Mines’ nearby Oyu Tolgoi deposits. It is common in very large porphyry copper-gold systems, such as those found in South America, for mineralization to occur along parallel structural trends and be comprised of numerous separate ore bodies. Strong geophysical signatures, in combination with copper-gold-molybdenum geochemical evidence, make Shivee West highly prospective.
The 2010 Lookout Hill Exploration Program is currently underway on Shivee West. Previous deep penetrating geophysical work has been re-evaluated over the 2009-2010 winter period. This re-evaluation will be combined with further geochemical, geophysical and geological surface work to generate new drill targets. Approximately 5,000 metres of follow-up drill testing is planned for later in 2010.
Togoot Licence
Coal was discovered in 2008 in the northwest corner of the Togoot licence. Nomkhon Bohr is the most advanced target and features a number of near-surface north dipping coal seams in carbonaceous stratigraphy believed to be of similar age to the Permian-hosted Tavan Tolgoi deposits, located approximately 75 kilometres to the northwest. Extensive drilling and trenching carried out in 2008 and 2009 traced Nomkhon Bohr over a strike length of 1200 m. Sufficient drilling data now exist to calculate a resource for the deposit.
The Nomkhon Bohr area has been divided into east and west zones. Two near continuous seams were intersected in the west and possibly four seams occur in the east. The seams are predictable from hole to hole and section to section with some fault offset of the seams. Coal in the eastern half is generally thicker and has lower ash content than that of the western half.
Nomkhon Bohr coal is medium rank bituminous, high in ash with variable sulphur. Coal-bearing horizons in drill holes can be up to 57 metres in apparent thickness; within these, multiple coal seams are usually present, with drill intercepts from 0.2 metres to 4.5 metres. Most of the coal seams dip moderately to the north. Due to the recessive nature of the coal seams, they often come to surface in shallow valleys where they are concealed by a thin veneer of desert sands. The geology has similarities to the Tavan Tolgoi coal deposits, although the coal at Nomkhon Bohr is of thermal quality.
