Porphyry copper deposits result from the complex interactions and feedbacks of many processes. Owing to the complexity, ... study of the Questa porphyry molybdenum deposit in New Mexico suggests that the ore fluid was probably derived from a source reservoir or reservoirs as deep as the middle crust (Klemm and others, 2008). Eight- to 15- or 20 ...
The oldest porphyry copper deposits (~77-74 Ma), which are coeval with the El Espíritu and Tresoro gold deposits, are distributed along a strip of land between the north coast of Sonora and the ...
Silver Ore Type and Mineral Deposit in the World. Abstract. The world mineral resources of silver ores are mainly located in Russia, Mexico, Canada, USA, Australia and Peru. major silver deposits can be …
In August 2024, Oroco announced a revised Preliminary Economic Assessment ("PEA") and updated Mineral Resource Estimate ("MRE") for the North Zone and South Zone of …
A 3D gravity model of the Copper Flat Mine was performed as part of the exploration of new resources in at the mine. The project is located in the Las Animas Mining District in Sierra County, New Mexico. The mine has been producing ore since 1877 and is currently owned by the New Mexico Copper Corporation, which plans o bringing the …
General Characteristics of Porphyry Deposits: Large scale: Porphyry deposits are large in size, often covering several square kilometers.; Age: Porphyry deposits typically form in a relatively short time period, typically 1 to 5 million years after the formation of the associated intrusive igneous rock.; Mineralization: Porphyry deposits …
site location #2 (mexico): copper, gold and silver in porphyry ore This concentrator processes 8,000 t/d of ore containing 0.9 – 1.1% copper, 48-53 g/t of silver, and 1.5 – …
The Suaqui Verde porphyry copper deposit is a small ore body of about 20 million tons of oxide ore grading 0.29% copper, located ~ 8 km E-NE of the town of Suaqui Grande in east-central Sonora, northwestern Mexico.The largest and better-known deposits occur in northern Sonora, whereas those from central and southern Sonora are smaller …
[1] The Questa porphyry Mo deposit in New Mexico provides a unique opportunity to study the relationship between pluton assembly and mineralization in a long-lived volcanic field. Magmatism along the caldera margin initiated at ~ 25.20 Ma and continued for ~ 770 ka. During this time, the emplacement of mineralizing intrusions …
The mass of porphyry deposits ranges over four orders of magnitude, with the mean size of a deposit ordered Cu > Mo ~ Au > Sn > W. Hydrothermal alteration is a guide to ore because it produces a ...
Re-evaluating genetic models for porphyry Mo mineralization at Questa, New Mexico: Implications for ore deposition following silicic ignimbrite eruption: QUESTA PORPHYRY MOLYBDENUM GEOCHRONOLOGY
- Fine crushed ore reclaimed and conveyed to the grinding circuit; - Grinding ore in a conventional ball mill circuit prior to processing in a flotation circuit. The ball mills will operate in closed circuit with hydro-cyclones to deliver an ore size of 80 percent passing 105 microns to the flotation circuit.
