American Creek Resources Announces Results from Magnetotelluric Survey on its Treaty Creek Property
(via Thenewswire.ca)
American Creek Resources is pleased to announce the results from a Magneto-telluric survey carried out by Quantec Geoscience on its Treaty Creek property in the summer of 2011. The survey was commissioned by Seabridge Gold (SEA: TSX-V) to survey along its proposed tunnel route for engineering purposes. American Creek authorized the survey (PR - May 30, 2011) as the survey will also detect porphyry rich mineralization and/or associated alteration zones to depth.
The proposed tunnel route crosses the Treaty Creek property over a distance of approximately 13 kilometers. A total of 40 (MT) sites were originally proposed to cover the length of the transect, however only sixteen sites were completed in the middle stretch of the tunnel route. The remaining 24 sites have been postponed to 2012.
The survey revealed a large conductive body at depth which extends upward to the surface and can be mapped between MT sites 214 and 216

This area contains gossanous outcrops along with surface mineralization and also includes the previously explored Orpiment zone.
The survey also shows a more prominent feeder extending over 3km from the large conductive body at depth. This feeder is approximately 750m wide and extends to the location of the Copper Belle zone where another large conductive body (less than 200ohm-m) appears on the survey. The north east tip of Copper Belle, a bulk-tonnage type gold-copper-molybdenum porphyry, appears to be located at the north east tip of this lowly resistive anomaly.
Highlights from the 2007 drilling on the Copper Belle zone included intersections of 0.93 g/t gold and 8.78 g/t silver over 76m; 0.76 g/t gold and 4.91 g/t silver over 70.5m; 0.83 g/t gold and 6.39 g/t silver over 46m; and 0.81 g/t gold and 3.8 g/t silver over 65m. Significant intersections from 2009 drilling included 241m of 0.80g/t gold ending in mineralization; 65.3m of 0.84 g/t gold; and 100m of 0.5 g/t gold.
This mineralization found in the Copper Belle drill results appears to coincide with the area of low resistivity found in the MT survey. As can be seen in the diagram below

the postponed sites LS 207 - LS 204 will show how far south west this conductive body extends down the West Nunatak once the survey is completed. These MT sites coincide with other mineralized zones identified as the Goat Trail zone, the Konkin zone, the AW zone, and the SW zone. Each of these zones contains strongly anomalous to high-grade gold values on surface. While the Konkin zone has historic high-grades including a trench sample taken in 1987 with 969 g/t gold over 1.2 meters (this appears to be an anomaly associated to a skarn), elevated gold values of 1.0- 5.0 g/t are more typical of surface mineralization along the West Nunatak.
The large conductive body at depth may also be the likely source for the Treaty Gossan (Eureka zone) which extends over 1 square kilometer. This massive gossan sits between MT sites LS 214 and LS 217 and is located 2km to the south of the MT array. The MT survey measures the ground in an inverted cone shape. Therefore the readings at depth cover an area much further to the north and south of the MT array.
American Creek President Allan Burton states "we were pleased that Quantec Geoscience conducted this survey as they are known for their imaging quality and have been used on a number of projects in the area. It is unfortunate that the West Nunatak portion of the survey was postponed given its extensive mineralization on surface and in historical drilling. However, the feeder system shown in the MT survey may help explain why American Creek has had exceptional results on the Copper Belle porphyry."
"Quantec Geoscience has the technology to greatly improve resolution closer to the surface, which when used in conjunction with the deep MT survey, can help identify targets and focus future drilling on the property. We look forward to using technologies like this to advance our Treaty Creek project as soon as we have resolved legal issues with our option partner."
