Copper Fox Metals Inc. ("Copper Fox" or the "Company") and its wholly owned subsidiary, Desert Fox Copper Inc. ("Desert Fox") are pleased to announce the results of a recently completed geochemical survey (Niton XRF) on its Sombrero Butte copper project. The Sombrero Butte project is located at the southern end of the Copper Creek (Bunker Hill) mining district in the Laramide porphyry copper province of southwestern Arizona.
The Copper Creek district is located 65 km North of Tucson, Arizona. This survey was completed in conjunction with the recent Quantec Titan-24 DCIP ("IP") survey (see news release dated September 8, 2015).
The 2015 Titan-24 DCIP survey identified chargeability and resistivity signatures that extended a considerable distance to the southeast beyond the limits of the large surface exploration target outlined in 2013. The objective of this geochemical survey was to explore the southeast portion of the project for the presence of geochemical anomalies that may indicate the presence of buried copper-molybdenum mineralization.
- The geochemical survey locating a number of coincident multiple element anomalies that occur within an area that measures approximately 2,500 metres (m) long by 800m wide,
- The geochemical anomalies show a positive correlation with the chargeability signature outlined in the recently completed Titan-24 DCIP survey, and
- The geochemical anomalies are underlain by the rocks of the Copper Creek granodiorite, Gray porphyry, Glory Hole Volcanics, Pinal Schist and breccia pipes.
Mr. Elmer Stewart, President of Copper Fox stated, "Our initial exploration target focused on the central and northern portion of the property where a significant number of mineralized breccia pipes are located. Since 2013 our exploration programs have identified a large surface exploration target that extends to the southeast which exhibits a positive correlation with the large chargeability/resistivity signatures defined by the 2015 Titan-24 DCIP survey. The combination of the surface target and the chargeability/resistivity signatures suggests the presence of a porphyry copper environment."
The geochemical survey was completed over the southeast portion of the area covered by the recent Titan-24 DCIP survey. The median values for copper and molybdenum was used as the threshold for anomalous values. The geochemical survey consisted of five lines (oriented northeast to southwest with line spacing of between 400m to 600m) and two additional lines oriented north-south located at the ends of the northeast-southwest lines. The northeast-southwest oriented lines range in length from 800m to 1,200m and the north-south lines were approximately 1,600m long and 2,400m long respectively. A total of 350 samples were collected during the survey. Each sample consisted of approximately 40 grams of leaves from a mesquite tree. The mesquite tree was selected as the sample medium due to their deep root systems. The samples were tested for a suite of 16 elements including copper, molybdenum, sulfur, iron, zinc and potassium with element concentrations measured in parts per million using a Niton XRF unit. Prior to commencing the survey, a sample from one mesquite tree was collected and analyzed daily at the start and end of each survey line to test calibration of Niton XRF unit.
No independent laboratory confirmation of the Niton XRF geochemical results from these sample sites will be undertaken. Niton XRF values reported are only indicative of the introduction of metals. They are not intended to be comparable to standard laboratory assays and should not be relied upon.
