Instead, recreational gold panning enthusiasts are interested in where to find gold in rivers, creeks and streams in what are called "placer" deposits. Placer deposits are created when gold is weathered out of rock over the aeons and moved by flowing creek water.
Whether you're a would-be prospector or just naturally curious, knowing which rocks contain gold can be something of a challenge. The unique properties of the yellow metal have made it prized, and it's also led to many techniques being used to find it in the various formations that have auriferous potential.
Placer Gold. Placer deposits of gold are formed by the concentration of the gold from the debris of gold veins and other deposits of gold in rock.

The Diggings™ is the most comprehensive free mining claim reference online. Search 3,921,409 up-to-date gold, silver, and other mining claim maps within the USA.
Gold deposits can be grouped into different geological or metal-association types with differing contributions to reserves, resources and production (Table 2). In Australia, the two most important are lode-gold deposits and copper-gold deposits, of which the latter includes iron oxide-copper-gold and porphyry deposits. ...
Mining companies employ a range of strategies to locate potential gold-bearing ground. These methods include both conventional prospecting strategies and complex geological and geophysical studies.
Successful gold prospectors don't just depend on luck. They use natural indicators to identify gold geology that has a high likelihood of producing gold.
Gold Maps Online™ contains over 438,870 active gold claims and 3,094,906 abandoned gold claims. All are located on public lands spread across twelve western states. Our abandoned gold claim maps reveal …
The problem is that gold occurs in so many different types of deposits. The indicators to look for in one place for one type of deposit don't always work very well for another. As an example, visible vein quartz on the ground …
Gold is either the only economically important metal or a major by-product in 11 well-characterized deposit types—paleoplacer, orogenic, porphyry, epithermal, Carlin, placer, reduced intrusion related, volcanogenic massive sulfide (VMS), skarn, carbonate replacement, and iron oxide-copper-gold (IOCG), arguably more than for those of any …
Gold occurs in two basic deposit types: lode gold and placer gold. A knowledge of how these types of deposits form and where they occur is essential for finding gold.
The problem is that gold occurs in many types of deposits, and what indicators work great for one type of deposit don't always work well for another. As an example, in some places the presence of vein quartz on …
Background Our client, Ground Truth Exploration, Inc., used AGI instruments and software to prove that gold deposits exist in areas of the Yukon Territory in Canada. The company had already ground truthed the gold deposit, but they wanted to prove that they could map any gold deposit locations in the Yukon frontier, and they used our tools to show how it …
Prospecting and exploration that is a search for precious metals deposits is not a simple process because big deposits were discovered a long time ago. There are several places with important content of precious metals waiting for skill prospectors. The large mining companies of the world are focused in big deposits and the small deposits …
The gold-telluride association was explained as an indication of melting of Te-rich sediments and subsequent mixing with mantle-sourced magma under subduction settings around the Pacific Rim (Cook ...
The goal has been primarily to map structure or contacts between lithologies where ore deposits are known to accumulate. The Matagami project (figure 2) was successful in mapping structural elements and in locating and identifying the Bell Allard sulfide orebody.
The regional settings of gold deposits are equally diverse, although attempts have been made (e.g. Mitchell and Garson, 1981) to simplify or categorize them. Guides, ... locating igneous and structural controls; host beds may give direct resistivity, magnetic or gravity signatures; clay alteration, fracturing provide VLF and resistivity
This study not only provides a new insight into the interpretation of gold distribution and aggregation in pyrite that has significant indication for gold deposit formation in the world, but also provides important evidences for geochemical exploration for concealed deposits based on nanoscale gold.
Hidden beneath American soil lies valuable deposits of rhodium, a precious metal with a price tag surpassing even that of gold. In this article, we'll delve into the world of rhodium to review the historical significance of rhodium in the US, pinpoint current locations of these valuable deposits, and explore the promising opportunities for …
The application of deposit-scale structural targeting to orogenic gold deposits is primarily concerned with locating volumes of higher-grade mineralisation (ore shoots) within a broader, host ...
NEW DATABASE POINTING WAY TO LOCATING GOLD, SILVER DEPOSITS COLUMBUS, Ohio -- Researchers here have built a database of maps covering a massive area in three western states which may help geologists locate concentrations of five different metals, including gold and silver. The new database, developed as part of a …
The quantitative and qualitative assessment of gold grains from samples of glacial till is a well-established method for exploring gold deposits hidden under glaciated cover. This method, which is widely used in the industry and has resulted in numerous successes in locating gold deposits in glaciated terrain, is still based on artisanal …
Surveys highlight the presence of shale and clay, which are indicators of coal deposits. Researching land history is a vital component to locating profitable coal deposits. The most successful areas were once swamplands, which contained peat.
Gold, a precious metal revered for its beauty and value, has captivated human interest for centuries. Prospecting for gold requires an understanding of the geological indicators that can hint at its presence in the soil. By recognising these indicators, prospectors and geologists can increase their chances of locating gold deposits.
9.3.2.1 Porphyry Deposits Figure 9.84: The mine workings at Morenci, Arizona. Porphyry deposits are a special kind of hydrothermal deposit. They form when hydrothermal fluids, derived from magmas at depth, carry metals toward the surface and deposit minerals to create disseminated ore deposits.
Nevada currently produces almost 75 percent of the annual U.S. gold yield. While this is primarily through professional mining, the state still allows people to recreationally pan—or more frequently, metal detect—for pieces of gold on publicly owned land. The highest-yielding land parcels are mostly claimed for private use…
