New Nadina Finds Porphyry Target at Silver Queen
July 21, 2011 GREENWOOD, BRITISH COLUMBIA – New Nadina Explorations Limited (TSX VENTURE: NNA) announces they have completed an aeromagnetic and ZTEM airborne geophysical survey and a follow up Titan 24 ground survey over its mineral claim group at the Silver Queen project, south of Houston BC. A preliminary interpretation of the data has identified two new geophysical targets south and east of the former producing No 3 Vein at the Silver Queen mine. An image showing locations can be viewed on the Company website: www.nadina.com.
The first – the Titan A target – is part of a two and half kilometer long trend mapped by the ZTEM survey. The known Silver Queen vein system sits at the north-west end and central part of the trend and the Titan A target sits close to the south-east end of this trend. The Titan A target is characterized as electrically resistive and chargeable and is interpreted to be a potential vein type system of the Silver Queen type.
Close to the Titan A target, to the east and below it, is the Titan B target. This is a conductive zone, with an associated high chargeability. The geophysical character of the Titan B target indicates that it could be a buried porphyry type bulk tonnage deposit. Preliminary depth estimates to the top of the Titan B target are on the order of 350 meters. This target is a blind geophysical target and can only be tested by drilling. The geophysical interpretation of the geological setting of the Titan B target is that it is close to an intrusive stock-like body that sits below the Silver Queen Vein system, and that it is located in a jog of a large regional fault zone. This jog may be a zone of accommodation where the regional structure passes close to the stock-like body.
Both the Titan A and Titan B targets are untested by historical drilling to the best knowledge of the New Nadina Exploration team. There were eight Titan 24 lines run, results from the four lines (3.6km each) has resulted in these two targets. Two lines extending over the south end of Owen Lake have not shown target potential. Modeling of the two lines covering George and Cole Lake areas are pending.
ZTEM is a new natural source airborne electromagnetic method operated by Geotech airborne of Mississauga, Ontario. It can routinely penetrate to depths in excess of one kilometer and is particularly suited to the exploration for bulk tonnage disseminated porphyry type targets. It is also sensitive to large resistive zones such as silicified vein systems. Titan24 is a high powered, state of the art, deep penetrating induced polarization and magnetotelluric ground based system operated by Quantec Geoscience of Toronto Ontario. Depths of investigation greater than 300 meters are routinely achieved with the Titan24 system.
Interpretation of the new geophysical data acquired over the Silver Queen project is ongoing at the Advanced Geophysical Interpretation Centre of Mira Geoscience in Vancouver, British Columbia for New Nadina. The ZTEM, aeromagnetic, and Titan24 data will be used in conjunction with the ongoing geological mapping and surface prospecting program at the Silver Queen project to direct the 8,000 meter summer drill program planned for this year at the Silver Queen project by New Nadina Explorations Ltd.
