Read Identification of Lithology & Base Metal Anomalies – Pathfinders for Gold Exploration Using Thermo Scientific Portable XRF Analyzers to learn about the successful use of portable XRF analyzers in gold exploration.There has been tons of gold found in Colorado over the years, but it isn’t particularly well-known for producing large gold nuggets. Although these geophysical methods can be crucial for gold exploration, geochemical methods, including XRF, are the only methods that can measure concentrations of gold and other associated elements. It’s much easier to find the pathfinder elements than it is to find gold and once found, they can help determine if gold is nearby. XRF sampling techniques are aimed at mapping the distribution of gold and in particular, the various pathfinder elements associated with gold (silver, copper, zinc, nickel, mercury, arsenic and barium). Modern gold mining takes advantage of technological advancements including Portable X-ray fluorescence (XRF) analyzers. The Ironstone nugget is now on display at a heritage museum in Ironstone Vineyards in California.

profiles the top five largest ‘named’ gold nuggets which are still in one piece and on display to the public: Most were melted down into gold bars or gold coins.
Many discoveries of large gold nuggets have been recorded, but few remain. CNN reports that members of the Association of Gold Seekers of Biella, Italy, are searching the banks of the Elvo river for gold that has washed down from the melting glaciers of the Alps. An LA Times article describes modern-day prospectors in the Mother Lode region of California searching for gold the old-fashioned way, using buckets and classifiers, hog pans and cradles. Today, the idea of finding gold holds the same allure. In 1848, the discovery of a gold nugget in northern California sparked the California Gold Rush, the largest mass migration in U.S.
