During the last few months, our team has been evaluating the potential of copper oxides and its corresponding enrichment zones. This video summarizes the 2 main highly prospective zones with copper oxides near surface. Some samples returned up to 9% Cu in oxides (>90% of soluble Cu) and >3%Cu in the enriched zone. Both zones follow the N-S structural trend along the skarn altered volcaniclastics + limestone unit. The Western zone extends approximately 400 x 20m and the Eastern zone extends 240 x 50m. The expected oxide and enrichment profile is about 40m. Compañía Minera Mohicano #IOCG #copper #mineralexploration #oredeposits

Australasian Metals Limited Identifies Additional Drill Targets at the Capella Project #AustralasianMetalsLimited (ASX: A8G) (Australasian Metals or the Company) has announced the successful completion of a comprehensive data review for the Ayres Rock Prospect, part of the #CapellaGoldProject in #CentralQueensland, Australia. The #AyresRockProspect is interpreted as a structurally controlled, epithermal-style quartz vein breccia system, hosted within rhyolitic ignimbrites of the Silver Hills Volcanics. The widespread alteration in the volcanic units is characterized by quartz, albite, chlorite, carbonate, pyrite, and occasional epidote, with rare occurrences of orthoclase.

⛏ Types of Gold Deposits Gold deposits can be classified into several main types based on their geological characteristics and mode of formation: ⛏ Magmatic-Hydrothermal Deposits ⚒ Porphyry Deposits Hydrothermal deposits associated with felsic to intermediate intrusions, characterized by low to medium gold grades but very high tonnages. Mineralization occurs in stockworks, fractures, faults or disseminated in the host rock. ⚒ Epithermal Deposits Formed at shallow depths from boiling hydrothermal fluids, these deposits have a wide range of gold grades. They are often associated with volcanic rocks. ⚒ Skarn Deposits Formed by the interaction of hydrothermal fluids with carbonate-rich rocks, producing gold-bearing calc-silicate mineral assemblages. ⚒ Iron Oxide-Copper-Gold (IOCG) Deposits A diverse group of hydrothermal deposits with iron oxides as a major component, found in various tectonic settings.

Our new geological model gave us clarity to continue exploring the potential of the San Martin ore body to depth. Although the #gold & #silver is in carbonaceous ore, the high tonnage we have available & the high potential shown from the new model led us to begin an intensive #exploration program focused on increasing the reserves of the economical carbonaceous ore. 👉 https://lnkd.in/gMdwKgQa

#skarn deposits skarn are calc -silicate rocks formed by replacement of carbonate lithologies either during reginal metamorphism or by contact metasomatic processes related to igneous intrusions, the word skarn was originally used by swedish miner's to indicate fe-rich calc -silicate gangue mineral. The skarn type alteration mineralization related to porphyry environment, A classification of skarn should take into consideration both the rock type and the mineralogical association of the replaced lithologies, the term Endo and exo skarn refer to the skarnification of igneous or aluminous rocks and carbonate rocks respective. Tectonic setting: skarn occur in most tectonic setting where there is magmatism and development of carbonate lithologies particularly of the porphyry related types are related to convergent boundaries ranging from oceanic island arcs to continental margins. The formation of skarn involves stages iso chemical metamorphism and metasomatism, towards the final phases cooling a retrograde stage occurs. Minerals assemblage: calcite, diopside, k-feldspar, graphite, following the cooling of quartz monoznite pluton. Economic interest: skarn are classified in term of their metal (fe,cu,pb,zn), and mo,w,sn. Gold is present by product of base metal.

THE PRIMARY GOLD FORMATION Primary gold refers to gold in its natural state, unaltered by geological or chemical processes. It is often extracted directly from gold deposits in the form of nuggets, glitter or wires. Primary gold is considered pure and untainted by other minerals It begins its formation in the Earth's crust through complex geological processes that often involve hydrothermal fluids. It is formed from MAGMATIC ROCKS rich in gold such as granite intrusions or porphyry-type volcanoes. These rocks are rich in elements such as iron, sulphur, and arsenic, especially sulphur that allows for differentiation or accumulation and its transport. Hydrothermal fluids, which are mineral-rich hot solutions, move through fractures and faults in casing rocks to form systems of transporting gold. These hydrothermal fluids often contain dissolved gold that is then deposited in weak areas along fractures and faults when it comes into contact with minerals that reduce the gold's solubility. Minerals such as quartz, calcite and sulfur often play an important role in the rush of gold creating veins and wires from a few centimeters to several kilometers long.#geology #structuralgeology #miningengineering

#Petrography of #gold-bearing quartz #veins involves studying their mineral composition, texture, and structure under a petrographic microscope. This includes identifying minerals like quartz, sulfides (such as pyrite and chalcopyrite), and gangue minerals. #Paragenesis refers to the sequence of mineral formation, which can be determined by studying the relationships between minerals and their textures, such as cross-cutting relationships or zoning patterns. By studying the paragenesis of gold deposits, #geologists can identify the sequence of mineral deposition, including the formation of gold-bearing quartz veins and associated sulfide minerals. This helps in delineating #mineralization zones within a geological area.

Types of gold deposits 1. Orogenic Gold Deposits: These are among the most common types, formed during mountain-building processes. They are typically found in metamorphic belts and are associated with quartz veins. 2. Epithermal Gold Deposits: Formed at shallow depths, these deposits are associated with volcanic and geothermal activity. They are typically found in zones with hot springs and are characterized by high-grade, low-sulfidation or high-sulfidation mineralization. 3. Carlin-Type Gold Deposits: These sediment-hosted deposits are characterized by fine-grained gold and occur in carbonate rocks. They are unique due to their invisible gold content and complex geochemistry. 4. Porphyry Gold Deposits: These deposits are associated with large igneous intrusions and are often found alongside copper deposits. They are known for their large size and low to medium-grade gold content. 5. Placer Gold Deposits: Formed by weathering and erosion of primary gold sources, placer deposits are found in riverb

Gold-bearing quartz veins and stringers are common features in many gold deposits. These veins and stringers are often formed by the hydrothermal deposition of gold from hot fluids circulating in cracks and fractures in the earth's crust. The gold is often associated with quartz and other minerals such as pyrite, arsenopyrite, and chalcopyrite. Exploration geologists often look for these quartz veins and stringers as they can be indicators of gold mineralization. Mapping the extent and orientation of these veins, along with sampling for gold content, can help geologists identify potential areas for further exploration and development. Is there a specific aspect of gold-bearing quartz veins and stringers you'd like to discuss? #gold #quartz #chalcopyrite #stringers #pyrite #exploration #geologists #sampling #alteration https://t.me/OreZone
