Stingray Copper Inc.: Positive Drill Results Continue to Define Oxide Copper Resource at El Pilar Property

TORONTO, ONTARIO--(Marketwire - Dec. 11, 2007) - Peter Mordaunt, CEO and Chairman of Stingray Copper Inc. ("Stingray") (TSX:SRY)(TSX:SRY.WT) is pleased to report the results of seven (7) additional drill holes completed at the Company's El Pilar Copper Property located in Sonora, Mexico. Stingray has now reported 49 drill holes completed on 8 drill sections from 9200 North to 8500 North This aggressive, in-fill drilling campaign has completed an additional 50 drill holes on 100 meter section spacing continuing to the south and also in the "Starter Pit Area" defined at the north end of the resource (See News Release 2007 -16). Three drill rigs are testing the oxidized copper mineralization that occurs as a flat lying to gently dipping horizon with vertical, HQ sized drill holes. The 43-101 compliant inferred mineral resource of 180 million tonnes grading 0.37% total copper calculated at a cutoff of 0.25% total copper is being systematically drilled at minimum 100 meter drill centers along its current 1.2 kilometer length and approximate 400 meter width. At a lower cut-off of 0.20% total copper, the inferred mineral resource is 237 million tonnes grading 0.33% total copper. The resource is open ended to the south and earlier drilling has outlined adjacent horizons of oxidized copper mineralization (See News Release 2007 -13, Table 2).

All holes reported from this central area of the resource continue to intersect wide intervals of significant oxidized copper mineralization similar in character to the previous wide spaced (200 meter) drill results completed by former property owner, Noranda Exploracion Mexico S.A. de C.V. These holes are posted at the Company's website and a map of the hole locations can be found at the link below or at the Company's website;

Copper intervals reported in Table 1 reflect approximate true widths and the principal copper mineral intersected is chrysocolla occurring as intrusive fragments in the host conglomerate. All drill core samples are split by the Company's staff under the direction of the Company's geologists and are delivered for assaying to ALS Chemex, Hermosillo, Sonora, Mexico.

(i)Ends in copper mineralization.


Stingray is working to reclassify the inferred mineral resource and develop the El Pilar as an open pit, heap leach, solvent extraction-electrowinning (SX-EW) copper mine. The oxidized copper mineralization as reported may appear lower in percentage copper than reported by sulphide copper developers and miners, however the capital and operating costs of heap leach, SX-EW operations are significantly lower. Additionally, such SX-EW copper operations produce a cathode copper product and not an intermediate concentrate that must be treated by a smelter and refiner.

Advanced metallurgical testwork has started at the Starter Pit Area where 15 drill holes have been shipped to Metcon Research Inc. in Tucson, Arizona. Sample preparation is underway on drill core that will be utilized for ore characterization and column leach testing. An additional 15 holes will be shipped prior to year end that will allow composite samples to be prepared in January 2008 for the column testwork.

Exploration to the north of the known resource at the 10 square kilometer El Pilar property is yielding encouraging copper and molybdenum results from recent surface work. Geological mapping, approximately 2.5 kilometers from the northern limit of the El Pilar resource, at the Arriba Zone, displays a strong fracture system that is oriented in a Northwest-Southeast trend. This trend is parallel to the regional structure that hosts many of the large, known porphyry copper deposits in Southern Arizona and Northern Sonora. Surface mapping of an area 2200 meters by 400 meters has identified many old workings within three distinct areas where high grade copper and molybdenum were mined historically for direct shipment to local smelters. Veins and silicified disseminations of fractured, acid intrusive rocks reveal malachite, azurite, chrysocolla (copper minerals) and molybdenite (molybdenum mineral).

In the central area of the Arriba Zone, 5 surface grab samples in waste dumps at the Old El Pilar Shaft area averaged 0.95% copper and 0.74% molybdenum. Although not overly meaningful in the context of where the samples came from, it is evidence that there is high grade metal in this structural system. 300 meters south of the Old El Pilar Shaft area is an outcrop of intrusive breccia that is observed on surface covering 15 by 20 meters. This breccia, the "HD Breccia", occurs as an intrusive penasco that extends 12 meter high (See Photo Gallery at website). Fragments within the matrix of this breccia are cemented with quartz, malachite and azurite (both, copper minerals). Follow up work in this area will consist of trenching and then diamond drilling.

Stingray is fully financed to complete the technical assessments, including extensive metallurgical column testing of the resource material at the El Pilar project, that will lead up to the preparation of a Feasibility Study. The Company has approximately $24 million in cash and cashable GIC's on deposit at the CIBC and no debt.
