As exploration is time-consuming, costly, and risky, determination of the erosion surface a metalliferous deposit before geophysical surveying drilling might be very helpful. Geochemical haloes can used to determine whether supra-ore or sub-ore thus reduce risk operations. The aim this investigation North ROK porphyry (NRPD) in northwestern British Columbia Canada using linear productivity (LP)...

The Ascutita porphyry Cu-Mo prospect is located in the SW Poiana Rusca Mountains, Romania. Current assessment estimates a resource of 110 Mt @ 0.15 % Cu-equivalent. In relatively low-grade deposits such as this, by-products Ag (2–3 ppm) are important determining economic feasibility overall orebody. Assayed Cu and have clear downhole correlation. absence other silver-bearing minerals, or correl...

Porphyry copper ore is a vital strategic mineral resource. It often associated with significant hydrothermal alteration, which alters the original mineralogical properties of rock. Extracting alteration information from remote sensing data crucial for porphyry exploration. However, current method extracting ASTER does not consider influence disturbing factors, such as topography, and ignores we...

Abstract Porphyry-type deposits are the main global source of copper and molybdenum. An improved understanding most favorable structural settings for emplacement these is necessary successful exploration, particularly considering that future discoveries will be made under cover based on conceptual target generation. A common view porphyry preferentially emplaced in pull-apart basins within stri...

The copper ore in Chilean porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide generally mined from various locations the mining site; thus, mineral composition, oxidation degree, particle size, and grade vary. Therefore, operation, it common to blend ores spots then process them using flotation. In this study, floatability of five types Cu–Mo b...

Heap leaching accounts for a fifth of global copper production, sourced primarily from porphyry ores, yet metal recoveries are often not optimal. Gangue, and its interaction with acid, plays an important role in such processes. Thus, a proper understanding of gangue minerals present in the ore, their textural relationships relative to particle size distribution, reactivity with acid under diffe...
