Copper Fox Metals Inc. ("Copper Fox" or the "Company") (TSX VENTURE:CUU)(OTC PINK:CPFXF) is pleased to announce preliminary sampling results (51 samples) from its 100% owned Mineral Mountain porphyry copper project, located in central Arizona. The results for additional samples from the project are pending.
Elmer B. Stewart, President and CEO of Copper Fox, stated, "The preliminary results are defining what looks like a large zone of porphyry style copper-molybdenum-gold-silver mineralization; the extent of which has yet to be defined. These results are encouraging and significantly advance our understanding of the copper potential of the project and will be used to establish the next work program to be completed. An interpretation of the results of the sampling program will be provided when all results are received and reviewed."
- The average metal concentrations for the samples within the mineralized zone are: 0.884% copper, 0.011% molybdenum, 0.122 g/t gold, and 29.8 g/t silver.
- The high copper concentration is interpreted to be due to the presence of chalcocite within the seventeen samples that assayed over 1% copper.
- The mineralized area outlined by these sample results covers approximately 800m by 600m and is open in three directions.
- Host rocks to the mineralization are Granodiorite, Aplite/Quartz Monzonite dikes, and Hornblende Diorite dikes, all of Laramide age.
- The mineralized area coincides with the previously reported historical chargeability anomaly.
- The mineralization exhibits a positive rhenium-tellurium association.
Mineral Mountain Project:
The Mineral Mountain project is located in a northeast trending structural lineament that hosts the porphyry copper deposits at Casa Grande, Resolution and in the Miami-Globe district in Arizona. The program was completed in that area of the project where historical exploration reports indicated the presence of a large area of copper +/- molybdenite mineralization and a coincident positive chargeability anomaly hosted in a Laramide age Granodiorite intrusion.
Analytical results for 51 samples from the area of reported mineralization have been received. The results for an additional 70 samples are pending. The range of values from within the sampled area for the 51 samples is shown below:
Seventeen of the 51 outcrop samples contain over 1% copper. The high grade nature of these samples is attributed to the presence of chalcocite. Chalcocite is a product of supergene leaching, a process common in porphyry copper systems in arid environments. Ten of the 51 samples contain between 0.5% - 1.0% copper. The average concentrations of the molybdenum-gold for these samples are in the range expected in a porphyry copper system. The relatively high silver concentration, although a positive parameter, is higher than would be expected in a porphyry copper system and is being further investigated.
Analytical and Sampling Procedures:
Outcrop and trench sampling (where applicable) as well as mapping lithologies, alterations, and vein assemblages were completed. Rock chip samples (approximately one kilogram) were collected from outcropping material to characterize the metals present in veins and other mineralized structures. Outcrop exposures within the sampled area are estimated to 10-15%. The samples were transported and delivered in person to Skyline Laboratories in Tucson, Arizona.
Samples were crushed to plus 75% -10 mesh, split and pulverized to plus 95% -150 mesh. Pulps were subjected to a multi-acid digest (HNO3, HF, HClO4) followed by analysis by ICP/OES. Gold was analyzed on a 30-gram charge by fire assay with an atomic absorption finish. Fluorine was analyzed by an ion-selective electrode. The Skyline's package code Te-5 was used to analyze the samples for the base and other trace elements. Skyline has an ISO/IEC 17025/2005 accreditation.
The first sample of each batch was a field blank. One certified standard pulp was inserted into the sample stream for each laboratory batch of twenty samples. A total of 4 blanks and certified reference standards were inserted with the sample batches for which analysis have been received.
