industrial development. Gold is one such mineral, and in regions like Magallanes, it is predominantly extracted from deposits known as \u201cplacers.\u201d These placers consist of mineralized zones formed by sediments of varying grain sizes, typically loose gravel and sand, that contain gold fragments or nuggets deposited by rivers or other natural processes. The gold in these deposits originates, for example, from quartz veins containing gold. When these veins are exposed on the surface, they undergo weathering, erosion, transport, and sedimentation processes. Gold is commonly found in sediments along active riverbeds or streams, but it can also be located in ancient riverbeds or paleochannels. These paleochannels, often situated near the surface, are easier to identify and extract compared to other types of gold deposits. The extraction of gold from placers is relatively straightforward. At its simplest, it requires only a pan or &#8220;chaya,&#8221; into which raw material and water are added. When the mixture is shaken, lighter materials float to the surface and are discarded, while the denser gold settles at the bottom of the pan.     <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-5dff4a1 e-con-full e-flex wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no wpr-column-slider-no wpr-equal-height-no e-con e-child\" data-id=\"5dff4a1\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-a2282f8 e-con-full e-flex wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no wpr-column-slider-no wpr-equal-height-no e-con e-child\" data-id=\"a2282f8\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-73a5df7 elementor-widget elementor-widget-text-editor\" data-id=\"73a5df7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>This simplicity has kept gold placer mining largely artisanal, requiring minimal technical planning or investment.

Second, the lack of prior knowledge about gold locations results in widespread environmental disturbance, as miners disrupt areas that could have been exploited more sustainably.

Their approach focuses on creating a &#8220;geo-mining-metallurgical&#8221; model during the early exploration stages, integrating geological, mining, and metallurgical data. This model was tested through a pilot project at a gold placer in Tierra del Fuego, located in the Cord\u00f3n Baquedano Mining District, approximately 35 km from Porvenir in the Magallanes Region. <\/p>\n<p>The process began with a series of drillings or wells to collect soil samples and analyze their gold concentration, measured in milligrams per cubic meter.<\/p>\n<p>For each 2 x 2 meter well, surface vegetation was carefully removed, a 1.5-meter-deep hole was drilled, and soil samples were collected. After sampling, the vegetation was replanted to ensure minimal environmental impact. The data gathered from these wells served as the foundation for the geo-mining-metallurgical analysis, which was conducted in three stages: <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-06376ac e-con-full e-flex wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no wpr-column-slider-no wpr-equal-height-no e-con e-child\" data-id=\"06376ac\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-3d87294 elementor-widget elementor-widget-image\" data-id=\"3d87294\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"718\" height=\"720\" src=\"https:\/\/divulgacion.ing.uc.cl\/wp-content\/uploads\/2024\/11\/Imagen3-1.png\" class=\"attachment-large size-large wp-image-5530\" alt=\"\" srcset=\"https:\/\/divulgacion.ing.uc.cl\/wp-content\/uploads\/2024\/11\/Imagen3-1.png 718w, https:\/\/divulgacion.ing.uc.cl\/wp-content\/uploads\/2024\/11\/Imagen3-1-300x300.png 300w, https:\/\/divulgacion.ing.uc.cl\/wp-content\/uploads\/2024\/11\/Imagen3-1-150x150.png 150w\" sizes=\"(max-width: 718px) 100vw, 718px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-8051ae3 e-flex e-con-boxed wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no wpr-column-slider-no wpr-equal-height-no e-con e-parent\" data-id=\"8051ae3\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;gradient&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-f235581 e-con-full e-flex wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no wpr-column-slider-no wpr-equal-height-no e-con e-child\" data-id=\"f235581\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-618034a e-con-full e-flex wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no wpr-column-slider-no wpr-equal-height-no e-con e-child\" data-id=\"618034a\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-280974d elementor-widget elementor-widget-heading\" data-id=\"280974d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Geological Mapping:<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-38689af elementor-widget elementor-widget-text-editor\" data-id=\"38689af\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>This stage involved creating detailed geological models through fieldwork and data collection.

The first model tested was the &#8220;Polygon Model,&#8221; a simple and widely used method in artisanal mining. In this approach, polygons are drawn around each sampling point, dividing the area into zones based on the samples collected. The gold concentration from each sample is then assigned to the entire polygon, assuming uniform mineral distribution within each zone. The second model, known as the &#8220;Inverse Distance&#8221; method, is more sophisticated. It calculates gold concentration at a specific point based on its distance from known values derived from samples. The closer the point is to the sample, the more similar its value will be. Lastly, the most complex model they analyzed is the &#8220;Kriging model.&#8221; Here, in addition to the factors considered in the previous models, the estimation error for each projection is also calculated.       <\/p>\n<p>After conducting these tests, the researchers concluded that the Inverse Distance and Kriging models are the most accurate and effective for planning the extraction process.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-3c15657 e-flex e-con-boxed wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no wpr-column-slider-no wpr-equal-height-no e-con e-parent\" data-id=\"3c15657\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;gradient&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-96613d0 e-con-full e-flex wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no wpr-column-slider-no wpr-equal-height-no e-con e-child\" data-id=\"96613d0\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-918865b e-con-full e-flex wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no wpr-column-slider-no wpr-equal-height-no e-con e-child\" data-id=\"918865b\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-88e5c5e elementor-widget elementor-widget-heading\" data-id=\"88e5c5e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Metallurgical Variables<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3a706c4 elementor-widget elementor-widget-text-editor\" data-id=\"3a706c4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>This last stage focuses on how to process the material to extract the gold.
