May 4 2022Porphyry copper deposits play an important role in the global economy. These deposits provide over 60 of the world s copper and include other important metals such as molybdenum gold and silver
Dec 1 2021The discovery of copper and gold bearing quartz stockwork mineralization which extend over at least 100m strike length (Figure 4) and which are similar to those seen on surface at the recently discovered Jaca porphyry copper project in the same district supports Altamira s belief that the Santa Helena project has the potential to host a
Oct 21 2021Vancouver Canada October 21 2021 Torq Resources Inc. 1. The belt is characterized by gold epithermal and gold copper porphyry deposits that are Oligocene Miocene in age including worldclass multimillionounce deposits such as Salares Norte La Coipa Cerro Maricunga Marte Lobo La Pepa El Volcan Caspiche and Cerro Casale (Figure 1).
porphyry copper deposit large body of rock typically a porphyry of granitic to dioritic composition that has been fractured on a fine scale and through which chalcopyrite and other copper minerals are disseminated. Porphyry copper deposits commonly contain hundreds of millions of metric tons of ore that averages a fraction of 1 percent copper by weight although they are lowgrade the
The Star Project is an Alkalic CopperGold Porphyry in the Golden Triangle of. CAVU owns 49 of the Star CopperGold porphyry project and has an LOI in place to option the remaining 51 from Prosper Gold Corp. The Property is subject to a 2 NSR and fully permitted for drilling and advanced exploration until 2026. The Star Project is an Alkalic
Copper in Porphyry Cabochons from New Mexico. Showing all 7 results. Cab144 Copper in Porphyry Cabochon. Measures (approx) long x wide x thick. Weighs ct. Add to cart. Cab1448 Copper in Porphyry Cabochon. Measures (approx) long x wide x thick.
Large Size Low Grade Porphyries typically have 100 million to 5 billion tonnes of ore with a lower grade ( to >1 copper). It is the size of these deposits that allow for bulk mining and economies of scale. Long Mine Life The size of porphyry systems usually mean that the life of the mine can be multidecades long.
4 days agoThe BP Zone is a km x km area of porphyry coppergold mineralization surrounded by a 4 km x 3 km propylitic alteration halo (see Figure 7). Historical drilling on the project has been
Oct 31 2022The mineralised porphyry shows encouraging potassic alteration within quartz diorite porphyry generally in association with the better copper grades. Retrograde sericite alteration overprinting is evident. It is anticipated that even higher copper grades may be present at depth below the sericite overprint zone.
Porphyry copper deposits are typically verylow grade with between and 1 copper. The main mineral is chalcopyrite which is finely disseminated through the host porphyritic rocks. The only reason these ore bodies are economic is because porphyries are huge with hundreds of millions of tonnes available in a fairly lowcost mining setting.
Oct 31 2022The mineralised porphyry shows encouraging potassic alteration within quartz diorite porphyry generally in association with the better copper grades. Retrograde sericite alteration overprinting is
In this report we have added 84 new porphyry copper deposits and removed 12 deposits. In addition some errors have been corrected and a number of deposits have had some information such as grades tonnages locations or ages revised. This publication contains a computer file of information on porphyry copper deposits from around the world.
6 days agoLibero Copper s district scale holdings cover over 1 000 km 2 encompassing most of the Jurassic porphyry belt in southern Colombia. Mocoa was discovered in 1973 when the United Nations and the
Porphyry copper deposits are best developed in association with the Laramide intrusive centers of northern Mexico and the midTertiary intrusions in southern Mexico. Other intrusionrelated deposit types occur within the same magmatic framework but they have different temporal and spatial correlations related to their igneous composition and
Jun 7 2022The Andes Mountains of South America host significant porphyry copper deposits. The region is the major global source of copper and an area of active mining exploration and development. The Andes region was included in USGS global compilations of porphyry deposits published by Singer and others in 2005 and 2008. Since that time many new discoveries and new resource data have become available.
Copper porphyry deposits range in size from 100 million tonnes to upwards of 10 billion tonnes of ore. Geologically the copper mineralization within porphyry systems can extend vertically for
Jan 27 2021In a similar way to our vast sedimenthosted coppersilver project in San Martin we have once again opened a new search space in Ucayali this time for coppergold porphyry systems. Big systems have big footprints and in a rare event field teams were able to sample up to copper in creeks within the first day or so of visiting the
Oct 14 2022The transition to new and green technologies is increasing the need for metals 1 2 such as copper for which demand is forecast to increase by 140350 from 2010 to 2050 3 4. Porphyrytype
6 days agoCopper Fox Metals Inc (TSXV CUU OTCQX CPFXF) has provided an update on its 100 owned Eaglehead polymetallic porphyry copper project approximately 50 kilometers (km) east of Dease Lake in British Columbia. "The 2022 program eliminated legacy data issues with the project database expanded the area of surface copper mineralization and revised the geology of the southwest portion of the
PROJECT OVERVIEW. Located close to the port city of Arica the Cristal Copper Project is situated in northernmost Chile adjacent to the Peruvian border. Covering the northern end of the famous West Fissure fault also known as the Domeyko Fault the claim area is highly prospective for large buried porphyry copper deposits.
Grasberg is the world s largest gold mine and secondlargest copper mine. It was originally discovered by geologists looking for the source of the rich alluvial gold deposits in the lowlands of Irian Jaya. Between 1990 and 2019 the Grasberg district produced 33 billion pounds of copper and 53 million ounces of gold.
