Copper Fox Announces Mineral Mountain Copper Project in Arizona
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jan 25, 2016) - Copper Fox Metals Inc. ("Copper Fox" or the "Company") (TSX VENTURE:CUU) (OTC PINK:CPFXF) and its wholly owned subsidiary, Desert Fox Copper Inc. ("Desert Fox") are pleased to announce that it has developed a new exploration stage porphyry copper project located in the Mineral Mountain area of central Arizona.
Location:
The Laramide porphyry copper province in Arizona is one of the most prolific copper mineralized districts in the world. The Globe-Miami, Resolution, Florence and Casa Grande copper districts are located in Central Arizona and occur along a northeast trend; essentially in a straight line (see table below). The Mineral Mountain copper project is located on this trend between the Florence copper deposit and the Resolution copper deposit. Public information on the copper resources in each of the above listed districts is set out below:
District | tonnes | copper (%) | contained copper (lb) |
Globe-Miami | 1,594,000,000 | 0.64 | 22,484,326,400 |
Resolution | 1,624,000,000 | 1.47 | 52,615,651,200 |
Florence* | 490,000,000 | 0.33 | 3,234,000,000 |
Casa Grande* | 740,000,000 | 0.90 | 14,678,640,000 |
In-Situ Leach ("ISL") project. Only oxide portion* of the deposit.
The porphyry copper deposits in the Globe-Miami and Resolution deposits are reported to contain significant concentrations of molybdenum.
Elmer B. Stewart, President and CEO of Copper Fox stated, "The discovery of new porphyry copper districts in geopolitical stable areas is fundamental to the future of the copper industry. The discovery of new porphyry copper deposits in jurisdictions such as Arizona requires an integrated more scientific approach including deep exploration such as the Resolution copper deposit. The Mineral Mountain project exhibits the surface characteristics of a buried porphyry copper deposit and provides Copper Fox considerable exposure to copper exploration in the Laramide porphyry copper province of Arizona in an easily accessible location".
Mineral Mountain Project:
The Mineral Mountain copper project consists of 209 mineral lode claims covering the interpreted surface expression of a buried porphyry copper system. This interpretation is based on published geology and geochemical data collected by Copper Fox.
The initial focus on the Mineral Mountain area was primarily due to several factors being;
- it was a former gold-silver mining district with numerous small underground mines and
- numerous occurrences of copper mineralization in outcrop.
The published geology for the area showed that the majority of the known mineralized fissures, veins etc. are exposed over an area that measures approximately 3 kilometres by 3 kilometres.
The Mineral Mountain area is underlain by Precambrian rocks that include Pinal schist, diabase and granite that have been intruded by Laramide age quartz monzonite, granodiorite and hornblende dacite dikes. Laramide age intrusive rocks and their associated country rocks are the host to the porphyry copper deposits in Arizona. The center of the property is cut by a prominent northwest trending system of faults along which the Laramide age quartz monzonite and granodiorite have intruded. North of this structural feature the area is primarily underlain by Precambrian rocks.
A preliminary geochemical stream sediment sampling survey completed by Copper Fox returned trace to abundant copper oxide mineralization with a suite of pathfinder minerals typically indicative of a porphyry copper environment (epidote, rutile, tourmaline, and pyrite) over an area that measured approximately 7 kilometres by 15 kilometres.
A follow-up systematic outcrop sampling program within the area outlined by the stream sediment sampling delineated three separate, stacked copper-molybdenum-gold-silver-tungsten geochemical anomalies within a maximum area of approximately 6 kilometres long and 3.0 kilometres wide. Metal values greater than copper 100 ppm, gold 10 ppb, silver 2 ppm, molybdenum 2ppm and tungsten 5ppm are considered anomalous. The range of values and Median Value for each element are set out below.
Element | Minimum | Maximum | Median Value |
Copper | 6 | 90,570 | 50 |
Molybdenum | 0.7 | 345 | 2 |
Gold | 2.5 | 7,030 | 10 |
Silver | 0.1 | 169 | 3 |
Tungsten | 0.2 | 444 | 1 |
Note: All values expressed in parts per million ("ppm") except gold which is expressed in parts per billion ("ppb").
The first zone shows more gold-silver enrichment and is underlain by Precambrian age Pinal Schist. The second zone is copper-molybdenum dominant and is underlain primarily by Laramide age quartz monzonite and granodiorite. The third zone is copper-molybdenum dominated and is underlain by Laramide age quartz monzonite and Precambrian granite and diabase. The project covers all three zones.
Alteration Assemblages:
The crude alteration assemblages observed in outcrop suggests a porphyry environment and consists of a central core of sericite that show good correlation with zones 2 and 3. Epidote alteration was observed on the periphery of zones 2 and 3. Specularite hematite and fluorite exhibits a correlation with zone 1.
A considerable number of vein assemblages typical of a porphyry environment were also observed during the field work. Sheeted biotite, epidote-quartz-hematite, quartz-hematite, quartz with sericite and albite selvages, chlorite, epidote-chlorite, quartz-magnetite, quartz-pyrite-jarosite, siderite-barite, fluorite-quartz with sericite selvages, quartz-tourmaline, hematite-quartz with potassic selvages and D veins were noted to occur in bedrock.
Supergene Mineralogy:
Supergene copper minerals consisting of malachite, chryscolla, chalcocite, melaconite and aurichalcite occur primarily in quartz veinlets hosted in the Precambrian rocks and Laramide intrusive rocks.
Analytical and Sampling Procedures:
A total of 171 outcrop samples were collected during the field work. Approximately one kilogram of selected rock chips was collected from mineralized outcropping material on a rough 400 meter by 400 meter grid to characterize the metals present in veins and other mineralized structures. Significant mine workings that did not fall near a grid sample site were also sampled. The samples were transported to Skyline Laboratories in Tucson, Arizona and delivered in person.
Samples were crushed to plus 75% -10 mesh, split and pulverized with standard steel 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.
Quality Control
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 13 blanks and standards were inserted with the sample batches for analysis. All standards were certified for copper, silver, and molybdenum, and one standard was certified for gold. All analytical results of standard pulps were within ±5% of accepted values.
