Entrée Gold completed the acquisition of 100%, royalty-free ownership of the Lookout Hill property in November 2003. Title to the property, which comprises three mineral exploration licenses (Nos. 3136, 3148, and 3150) covering 179,590 hectares, has been registered in Entrée Gold's name by the Mongolian government's Geological and Mining Cadstre office and can be viewed on the Cadastre website at http://www.mram.mn/l_reg12.xls.
The property is underlain by mainly Silurian to Devonian volcanic rocks that have been intruded by a number of Carboniferous, and younger, intrusions. The most important intrusions appear to be a series of small, hydrothermally altered, fine grained quartzose stocks, quartz-feldspar porphyries and syenite dykes. Large structurally bounded zones of advanced argillic quartz-alunite alteration grade laterally out into quartz-sericite, sericite/illite, clay and chlorite zones and appear to be associated with the small intrusive bodies. In other areas there are widespread siliceous, leached rocks with sericite and sericite/illite alteration passing outward into peripheral propylitic zones. Pyrite occurs locally but overall the rocks are severely weathered and leached at surface. In a few places in the zones of alteration quartz stockworks are present indicating a porphyry copper style of mineralization. A chip sample from one quartz vein near the margin of one of the altered zones returned 8.05 grams gold per tonne.
Reconnaissance geochemical sampling has identified zones with anomalous gold values in soils and rock samples. Induced polarization geophysical surveys have outlined large zones of high chargeability that are coincident in most areas with the highly altered rocks.
In total, seven zones of exploration interest have been identified from combined geological, geochemical and geophysical studies. A drilling programme was conducted in 2004 that consisted of 18 drill holes, totaling over 4,000m. The drilling programme for 2005 was originally planned for 8,000m but will likely expand because of the private placement made by Rio Tinto and Ivanhoe that closed in July 2005.
LOOKOUT HILL - SOUTHERN MONGOLIA
-
One of the premier frontier exploration properties in the emerging South Gobi gold-copper camp, Mongolia.
-
Entrée’s 179,590 hectare Lookout Hill property completely surrounds Ivanhoe’s approximately 8,500 hectare Turquoise Hill property.
-
Lookout Hill hosts probable extensions to Ivanhoe’s porphyry gold-copper mineralized system.
-
The extension of the Hugo North Deposit mineralization was confirmed (see press release - April 14, 2005).
-
Hugo North Deposit mineralization was confirmed to extend 625m onto Copper Flats (see press release – September 28, 2005).
-
The Hugo North extension, onto Entrée’s ground, contains an intercept of 608 metres averaging 3.24% copper and 0.82 gm/t gold (Cu equivalent – 3.77%) – see the June 6, 2005 press release.
-
An Inferred Resource estimate was released February 1, 2006. This initial Copper Flats inferred resource is estimated to be 190 million tonnes at an average grade of 1.57% copper and 0.53 grams of gold per tonne (g/t) for a copper equivalent grade* of 1.91%, at a 0.6% copper equivalent cut-off. (see press release – February 1, 2006).
-
Mineralization is believed to extend 1,300 metres, based on the results of Hole EGD081B, also released on February 1, 2006.
-
The company recently acquired three additional mineral licenses: Oyut Tolgoi, Asgat Uul and Onts Uul, all located in northwestern Mongolia.
