Pre-Feasibility Drilling At The Ann Mason Project

 

VANCOUVER, BC - Entree Gold Inc. has received complete assay results from the first 20 holes of the previously announced pre-feasibility drill program at its 100% owned Ann Mason project in the Yerington district of Nevada.

Highlights from initial drill results include: EG-AM-14-041 with 390 meters of 0.35% copper, EG-AM-14-050 with 176 meters of 0.35% copper, EG-AM-14-046, the eastern-most drill hole, with 112.3 meters of 0.34% copper, EG-AM-14-057 with 327.4 meters of 0.38% copper, and EG-AM-14-065 with 150 meters of 0.38% copper.

Greg Crowe, President and CEO of Entree stated, "The assay results received to date from our in-fill drill program look very promising, and will be used to upgrade the current mineral resources to the Measured and Indicated categories. Ann Mason is revealing itself to be a large, uniform copper deposit with very consistent grades, located in one of the best mining jurisdictions in the world. This drill program represents a significant step towards pre-feasibility, and advances Ann Mason along a development timeline. The next step will be to complete an updated resource estimate and PEA in the first half of 2015, and commence updated metallurgy studies."

The infill drill program commenced in August 2014 and, with the final hole in progress, will be completed by the end of January 2015. The program comprised 40 holes and a total of approximately 19,200 meters combined reverse circulation ("RC") pre-collars and core. Assay results on the last 20 holes are pending. The work is designed to upgrade the mineral resources contained in the 2012 Preliminary Economic Assessment Phase 5 pit ("2012 PEA" - see News Release of October 24, 2012) from Indicated and Inferred to a mix of Measured and Indicated categories. An updated drill plan and a table of detailed drill hole information is available on www.entreegold.com.

The 2012 PEA envisions a 24 year conventional open pit mine and sulphide flotation mill operating at a throughput rate of 100,000 tonnes per day and is based on mineralization contained within the Phase 5 pit. Over the life of mine, the 2012 PEA estimates average copper recovery of approximately 93%, producing a clean, 30% copper concentrate with average annual production of 214 million pounds of copper. There is potential to increase the mine life of Ann Mason through additional drilling and engineering studies.

The 2012 PEA is preliminary in nature and includes Inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the 2012 PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
