Northern Tiger Resources Inc. confirms that a number of high-priority targets have been identified by a deep-penetrating geophysical survey done by Quantec Geosciences Ltd. (the Titan 24 survey) at Sonora Gulch in the Dawson Range, Yukon. Two holes have been completed in a planned 3,000-metre diamond drilling program that commenced on June 29.
“This is a large and attractive target based on the results of the Titan 24 Survey combined with the Cu-Mo-Au-Ag geochemical signature and similar age of intrusive host rocks to the nearby Casino copper-gold-molybdenum porphyry deposit,” says Greg Hayes, President of Northern Tiger. “An intense IP response mantling around a non-chargeable core in our target area is very encouraging and further supports our porphyry exploration model.”
As disclosed in a previous news release (February 25, 2010), many common indicators of a porphyry system have been identified on the project, including a large potassic alteration zone, a copper-molybdenum soil anomaly, and flanking gold and base metal mineralization.
Based on analysis of the Titan 24 Survey and in consultation with Northern Tiger’s geologists, Quantec has recommended 14 drill holes to test 9 separate but spatially related high priority chargeability anomalies. These anomalies cover a 2 by 1-kilometre area, surrounding and draping over a less chargeable core. Chargeable zones are also associated with more conductive areas within the resistivity data. Many of the chargeability anomalies are related to a zone of intersecting structures that may be important for ground preparation. In addition, an airborne magnetic survey defined an arcuate magnetic anomaly at the contact between Cretaceous intrusions and the surrounding country rock.
The Titan 24 Survey consists of 6 lines (each 2.4 kilometres long) spaced 400 metres apart, covering an area of approximately 4.8 square kilometres. Direct current resistivity and induced polarization data are mapped to depths of approximately 750 metres. A presentation of the Titan 24 results will be posted on Northern Tiger’s website.
