Entrée Gold Enters into Agreement to Explore for Porphyry Copper in Southwestern U.S.A.
July 18, 2007
Vancouver, B.C., July 18, 2007 - Entrée Gold Inc. (TSX:ETG; AMEX:EGI; Frankfurt:EKA – “Entrée” or the “Company”) announces that, subject to TSX acceptance, the Company has entered into an agreement with Empirical Discovery LLC to explore for and develop porphyry copper targets in southeastern Arizona and adjoining southwestern New Mexico. The principals of Empirical have extensive experience in exploration for copper porphyries in the Americas, as well as access to proprietary geophysical interpretation techniques of particular application to large regional datasets. These techniques have been modeled using a number of known deposits, and the criteria developed will be used to identify buried targets from the regional database.
Initial targeting is underway, and applications for eleven contiguous mineral exploration permits in southeastern Arizona totaling approximately 8.5 square miles (22 square kilometres) have recently been approved. The permits cover several buried porphyry copper targets interpreted from regional geophysical and geological data. Surface work will commence in the fall. Additional property acquisitions may occur as further targets are defined.
Under the terms of the agreement, Entrée has the option to acquire an 80% interest in any of the properties by incurring exploration expenditures totalling a minimum of US $1.9 million and issuing 300,000 shares within 5 years of the anniversary of TSX acceptance of the agreement. If Entrée exercises its option, Empirical may elect within 90 days to retain a 20% participating interest or convert to a 2% NSR royalty, half of which may be purchased for US $2 million.
2007 Exploration Update
Sol Dos, Arizona
Three diamond drill holes totaling 2,386 m have been completed on the Sol Dos copper porphyry target and assays have been received for the first two holes. These holes were drilled to explore untested portions of the Sol Dos copper porphyry system judged to have potential to host higher-grade copper mineralization. Drill hole locations were based on a geological analysis of existing drill data and the results of deep penetrating IP/resistivity and ground magnetic surveys conducted in late 2006.
Drill hole EG-SD-07-001 was collared in the center of the Sol Dos system to test a zone of interpreted strong potassic alteration defined by the strongest ground magnetic response. This hole encountered long intervals of anomalous copper values (378 m averaging 0.06% Cu), with short intervals of higher grade material in highly altered breccia and monzonite porphyry cut by pyrite, pyrite-magnetite, and magnetite veins. Hole EG-SD-07-002 tested a strong IP target coincident with a magnetic low located on the northeast periphery of the porphyry system. No significant copper values were encountered. Hole EG-SD-07-003 was drilled to test the contact between the outer phyllic alteration assemblage and the central potassic zone of alteration on the southwest margin of the Sol porphyry system. Strong pyrite mineralization is present in silicified and brecciated siltstones and conglomerates that are cut by monzonite porphyry dykes. Assays are pending for EG-SD-07-003.
The initial planned program is now complete. Additional exploration will be decided upon, after assays are received for the final hole and all data has been compiled and reviewed.
Entrée commenced the 2007 exploration season in May. To date the field crews have conducted 3,093 m of drilling on several targets including the Moly Zone, Ring Dyke and Zone III. Additionally, the grid-based ground geological, geochemical (3,468 samples) and geophysical coverage (17 x 18 km) has been greatly expanded.
Four holes (EG-07-050 to 053) were drilled to an average depth of 170 metres in the Moly Zone. Hole EG-07-052 intersected 43 metres (from 59 m to 102m) of 0.048% Mo, including 29 m of 0.068% Mo. Hole EG-07-053 encountered 0.01% Mo over 10 m. The other hole did not encounter significant mineralized intervals. Exploration, including drilling, is on-going and is planned to continue through to the end of the fall season.
At the Manlai Project in Mongolia 1,960 m of diamond drilling has been completed in two holes on the East Target area. This target is centred on coincident magnetometer and induced polarization anomalies, and anomalous copper and molybdenum in soil geochemistry, with surface exposure of stockwork quartz veining containing chalcopyrite and bornite over an area of 500 x 150 m. Hole EGU07013B (968 m) contained variable quartz stockwork veining with minor visible copper and molybdenum sulphides over a length of 510 m. Complete assays for this hole are pending. No significant mineralization was intersected in the second hole (EGU07014).
A decision on additional exploration will be made once all data has been received, compiled and reviewed.
Entrée - Ivanhoe Agreement Area
Ivanhoe Mines Ltd. (TSX: IVN, NYSE: IVN; NASDAQ: IVN – “Ivanhoe”) continues its exploration of the joint Entrée-Ivanhoe agreement area both to the north and south of the Oyu Tolgoi mining licence.
Mongolian Government Initiatives
The Mongolian parliament has reconvened for approximately one month to continue consideration of outstanding issues, including the ratification of the draft Investment Agreement between the Mongolian government, Ivanhoe Mines and Rio Tinto. This agreement will facilitate long-term investment in major development projects such as Oyu Tolgoi.
