COPPER FOX ANNOUNCES IP SURVEY FOR MINERAL MOUNTAIN COPPER PROJECT
Copper Fox Metals Inc. and its wholly owned subsidiary, Desert Fox Copper Inc., plan to complete a deep penetrating induced polarization (chargeability/resistivity) survey on its 100-per-cent-owned Mineral Mountain copper project located approximately 15 miles east of Florence, Ariz.
Highlights
- 12.5 kilometres of geophysical survey to test the continuity at depth of the copper mineralization in target No. 1 and target No. 2. The survey will map the chargeability and resistivity signatures to an average depth of 600 metres below surface. Target No. 1 is hosted in Laramide age mineralized multiphase intrusive stock and measures 4,500 metres long by up to 2,000 m wide;
- Target No. 2 is hosted in Precambrian granite and diabase, measuring 2,800 m long by 400 m wide, located approximately 800 m southeast of target No. 1.
Elmer B. Stewart, president and chief executive officer of Copper Fox, stated: "The objective of the geophysical survey is to advance the project to the drill-ready stage by mapping the chargeability/resistivity signatures below the copper mineralization exposed in outcrop on both targets. Assuming positive results, the data will be combined with previous work to select drill hole locations."
Geological model
The geological model centres on a multiphase Laramide age intrusive with mineralized and non-mineralized granodiorite phases and a mineralized quartz monzonite phase intruding the Precambrian Pinal schist. The intrusive has been age dated at 69.7 million annum plus or minus 400,000 million annum utilizing uranium/lead zircon age dating and is cut by a series of syn-mineralization and late-stage dikes of varying composition. Porphyry copper style of mineralization and alteration occurs in a large portion of the stock.
Petrographic studies
Petrographic studies indicate an early potassic phase, overprinted by pervasive sericite and late-stage propylitic alteration and transformation of primary chalcopyrite to secondary malachite, covellite and chalcocite due to weathering/oxidization/enrichment processes that were active after the Laramide hydrothermal event.
Mineralization
Target No. 1 consists of three overlapping styles of copper mineralization occurring as disseminations, and in northeast- and northwest-striking quartz vein/veinlet stockwork and fractures.
In target No. 2, copper mineralization occurs in quartz vein/vein stockworks and fractures hosted in Precambrian Pinal schist, diabase and the Ruin granite with similar strike and dip directions to that observed in target No. 1.
Analytical results
The copper mineralization exposed in outcrop is interpreted to represent the lower portion of the supergene zone that resulted from cycles of weathering/oxidization/metal enrichment that occurred after the Laramide hydrothermal event. The supergene process increases certain metal concentrations at the bottom of the weathered zone which suggests that the samples used to determine average concentrations, median values and range of metal concentrations shown in the attached table are not necessarily representative of the mineralization on the property.

Analytical and sampling procedures
Analytical results used in this news release represent selected rock chip samples of the three styles of mineralization from the Mineral Mountain project. The samples were collected to characterize the base metals and trace element geochemistry present in veins, other mineralized structures and outcrops. The samples were picked up from the site by Skyline Laboratories of Tucson, Ariz.
The samples were crushed to plus 75 per cent minus 10 mesh, split and pulverized to plus 95 per cent minus 150 mesh. Pulps were subjected to a multiacid digest (HNO3, HF and HClO4). Gold was analyzed on a 30-gram charge by fire assay (FA-01) with an atomic absorption finish. Skyline's package code TE-5 was used to analyze the samples for the base and other trace elements. Metal concentration in samples exceeding the upper limit of detection was assayed for copper using (MEA) and silver (FA-04). Skyline has an ISO/IEC 17025/2005 accreditation.
