De Grey Mining Limited announce an updated Mineral Resource for the Mt Berghaus Gold Prospect forming part of the 100% owned Turner River Project, located near Port Hedland in the Pilbara region of Western Australia. The update was completed to include the results of RC drilling recently completed by De Grey. Modelling and estimation was completed by Payne Geological Services Pty Ltd, an external and independent mining consultancy. Previous Resource: The previous resource estimate was 0.9Mt @ 1.4g/t for 43,000oz using a 0.5g/t cut-off. The new resource shows an overall 227% increase in reported ounces. This increase is due to the definition of extensions to the known mineralisation at Mt Berghaus and the discovery of new mineralised zones at North Lode and West Berghaus Prospects. The Mt Berghaus Central, North Lode and Berghaus West deposits are controlled by the Mallina Shear Zone and occurs within deformed metasediments of Archean age. Mineralisation is developed within a NE-SW striking, sub-vertical zone with resource grade mineralisation defined to date in three separate areas. The Mt Berghaus zone has a strike extent of 1.4 km while the North Lode and West Berghaus zones have strike extents of 160m and 350m respectively. All zones have been reported above a depth of 120m. Approximately half of the resource drill holes at the Mt Berghaus project were completed by DEG in 2016. Previous drilling was largely completed by DEG in 2004 and 2005. An additional nine diamond holes were drilled by a joint venture partner in 2014. The main Mt Berghaus zone has now been drilled at 20m hole spacings on 40m spaced cross sections. The West Berghaus and North Lode mineralisation has been drilled with a small number of holes at 20m hole spacings on 80-100m spaced cross sections. A total of 114 RC holes and 10 diamond holes define the Mineral Resource.
