Expanded Copper-Molybdenum Footprint At Mineral Mountain
VANCOUVER, BC - Copper Fox Metals Inc. reported the results of the compilation of the 2015 and 2016 rock sampling programs on its 100% owned Mineral Mountain property, a Laramide age copper-molybdenum-gold project located in central Arizona. Elmer B. Stewart, President and CEO of Copper Fox, stated, "The compilation work indicates that a large area of porphyry style copper-molybdenum-gold mineralization hosted in Laramide age rocks has been identified at Mineral Mountain. This porphyry copper environment is located in the same northeast trending structural lineament that hosts the porphyry copper deposits at Casa Grande, Florence, Resolution and in the Globe-Miami district, Arizona."
The Mineral Mountain project is located in the northeast trending Jemez structural lineament, the same trend that hosts the porphyry copper deposits at Casa Grande, Florence, Resolution and in the Globe-Miami district in Arizona. In 2015 Copper Fox conducted a bedrock mapping and sampling program on a 400m spaced sampling grid. The results of the 2015 and 2016 bedrock sampling programs were compiled and interpreted.
The portion of the project discussed displays a classical porphyry style alteration pattern consisting of a potassic core, an intermediate phyllic zone and an outer more extensive propylitic alteration. The mineralized trend identified as a result of the compilation work is located within potassic and phyllic altered rocks. The area of copper-molybdenite-gold mineralization outlined in 2016 is hosted in potassic altered Laramide age rocks. The potassic alteration zone (potassic envelopes, secondary biotite) measures approximately 1,200m by 900m and is terminated to the northeast by an interpreted graben. The potassic alteration is restricted to Laramide age rocks and follows the same trend as the Laramide age hornblende diorite dikes located within the mineralized area.
The phyllic zone (quartz-sericite +/- pyrite) surrounds the potassic zone and is terminated to the north by the same graben that terminated the potassic alteration zone. Phyllic alteration extends to the southwest over a horizontal distance of approximately 3.0km and ranges in width from 1.4 to 2.0km. At the south end of this zone, sericitic alteration extends a considerable distance into the Precambrian rocks. This alteration (hematite-epidote-late stage epidote veining) is not mineralized and surrounds the zone of sericitic alteration.
The compilation of the 2015 bedrock sampling results has outlined two areas of mineralized rock located to the northeast and southwest of the mineralized zone outlined in 2016. These two areas of mineralized rock plus the area of mineralization outlined in 2016 define the mineralized trend. The delineation of this zone is based on 10 samples located northeast of the mineralized area identified in 2016. The mineralized samples are hosted in potassic and phyllic altered Laramide age granodiorite and quartz monzonite. The zone covers an area of approximately 1,000m by 500m and terminates against the interpreted graben. The mineralization in this zone is hosted in classical "A" veins, as well as in veins with sericitic and potassic envelopes. Hematite is common to the veins. Jarosite, pyrite and secondary biotite have also been observed in association with the mineralized quartz veins. This zone is located to the southwest of the 2016 sampled area and is defined by 18 samples, 12 of which contain either greater than 1,000 ppm copper or greater than 60 ppm molybdenum. The mineralization is hosted in steeply dipping quartz veins with sericitic envelopes. Chlorite and late stage epidote veinlets have been observed at several sample sites. Hematite is common to the mineralized veins. The average and median copper concentration for this zone is strongly influenced by the sample that contained 90,570 ppm copper. Assigning a zero value to this sample, the average copper content of the zone is reduced by 50% to 5,052 ppm copper and the median value is reduced by 45% to 221 ppm copper.
The addition to the metal assemblage and alteration, the mineralized trend is characterized by a rhenium-bismuth-tellurium geochemical association, porphyry style "A" and "D" veins and chalcocite veins (with minor covellite). The main copper minerals are chalcocite, chrysocolla and malachite.
