    Cratón Amazónico como posible origen de la ocurrencia aurífera tipo placer en el Oriente Colombiano
    (Universidad EAFIT, 2022) Restrepo Rios, Nicolás; Gómez Gutiérrez, Diego Felipe
    Through a complete work of collecting mineralogical, geochemical, geochronological data from previous studies, together with the compilation of geological interpretations made in Proterozoic rocks in southeastern Colombia, a preliminary evaluation is made about the possibility that these rock units may host gold mineral depositsthat have been hosted during the early stages of formation of these bodies, to identify possible primary sources that are contributing secondary gold manifestations in placers on the riverbanks.

    El sector energético como activo refugio : un análisis del XLE tras la invasión de Rusia a Ucrania
    (Universidad EAFIT, 2025) Vera Cortés, Alfonsina del Mar; Puerta Álvarez, Henry Daniel
    This study analyzes whether the U.S. energy sector, represented by the XLE ETF, can be considered a safe haven asset in the context of disruptive geopolitical and economic events, such as the Russia-Ukraine war and the COVID-19 pandemic. Using daily data from 2019 to 2025, the behavior of XLE, the S&P 500, gold (XAU/USD), oil prices (WTI and Brent), and inflation expectations (sourced from the FRED database) are examined. Through statistical and graphical tools, the analysis shows that XLE experienced a significant recovery after the onset of the conflict, remaining relatively stable compared to the volatility of other assets such as oil and gold. In contrast, gold—traditionally viewed as a safe haven—lost stability after the war began, with a delayed recovery. The differing behavior of WTI and Brent highlights the influence of regional geopolitical factors. Inflation expectations also played a key role in shaping asset dynamics. The results suggest that, although gold remains relevant as a safe haven, the U.S. energy sector—particularly the XLE—has gained prominence as a potential defensive alternative for investors during periods of high uncertainty.

    The "Feasibility Study for the Creation of a Gold Refinery in Antioquia" is a report that analyzes the feasibility of building a gold refinery in the Antioquia region of Colombia. The study is divided into several sections that address different aspects, such as market analysis, technical feasibility, financial analysis, and environmental impact. In the market analysis, the demand for gold and supply in the international and national markets is examined. The competition in the sector is also studied, and the main potential customers are identified. Regarding technical feasibility, the availability of raw materials and the processes necessary for gold refining are analyzed. Available technologies are studied, and an assessment of construction and operation costs is made. In the financial analysis, an investment study is conducted, and the profitability of the project is evaluated. Projected revenues and costs are examined, and the investment payback period is calculated. Finally, in the environmental impact analysis, possible environmental impacts are evaluated, and measures are proposed to mitigate them. In conclusion, the study concludes that the construction of a gold refinery in Antioquia is viable and profitable and has the potential to generate significant economic benefits for the region.

    Metalogénesis en depósitos tipo placer asociados genéticamente con áreas ígneo-metamórficas en el Bajo Cauca : caso de estudio Mina Lucky (Antioquia – Colombia)
    (Universidad EAFIT, 2023) Chávez Arrieta, María Alejandra; Gómez Gutiérrez, Diego Felipe
    Historically, mineral extraction in Colombia has taken place on a small scale and in an artisanal manner, serving as a means of livelihood for some communities in the country. Gold has been considered an economic driver in the development of the northeastern Antioquia region, particularly in the Mining District of Bajo Cauca-Nechí, renowned for gold exploitation in Quaternary age placer deposits associated with terraces and alluvial formations, generated by the fluvial dynamics of the Cauca and Nechí rivers. However, over time, petrographic analysis has not been conducted to identify the mineralogical composition of the exposed lithological units in the area. Petrographic/metallographic characterization enables the establishment of transport conditions and deposition mechanisms for gold particles. This approach will provide detailed information on the compositional and textural features of mineralization present in the alluvial deposit of the study area. The mineralogy of the analyzed deposit in its concentrates of black sands is composed of oxides such as Magnetite (Mt), Ilmenite (Ilm), and Hematite (Hm), accompanied by laminarly arranged fractions of gold. From a petrographic perspective, the mineralogical relationship was analyzed, revealing a significant presence of Magnetite with small inclusions of sulfides like Pyrite (Py) and the existence of silicate group minerals such as Zircons (Zir), Garnet (Gnt), and Epidote (Ep). This study focused on analyzing the mineralogical composition and textural features of the paleoplacer-type deposit in Bajo Cauca. This allowed the establishment of information regarding the geological conditions during the formation of the observed mineralogy in the deposit. The information will serve as a foundation to establish specific aspects of the genetic model of the deposit, which is crucial in the exploration and exploitation of mineral deposits, facilitating an understanding of the conditions in their source areas that favored their formation.

    Minería mecanizada en el Departamento del Chocó : ¿fuente de crecimiento económico y bienestar?
    (Universidad EAFIT, 2022) Albornoz Torres, Sandra Vanessa; Cújar Couttin, Darío; Muñoz Mora, Juan Carlos
    This article takes a descriptive approach to the relationship between the increase in mechanized gold mining and the evolution of economic growth and social welfare in the department of Chocó. The consolidation of gold production in the region has generated extra income to the municipalities through the General Royalties System (SGR), which increases the funds available for social investment and growth. To verify this intuition, the paper uses descriptive statistics to analyze trends in mining production in Chocó and the various social investment projects financed with royalty revenues. In addition, information is presented on the behavior of socioeconomic indicators related to education, health, employment and poverty, with the purpose of observing whether the social investment from royalty revenues is reflected in the variation of the behavior of these variables. The descriptive analysis shows that despite the increase in production and SGR revenues in Chocó, the results in education, employment and poverty do not show a significant improvement. However, despite this, the contribution from royalties is not considered ineffective, because the behavior of these indicators is linked to structural problems of the different governmental entities that make up the department, which is beyond the scope of this work.

    Predicción del precio del oro en el mercado spot y el tipo de cambio USD–COP para la optimización del rango de cobertura en derivados de las compañías exportadoras del sector minero
    (Universidad EAFIT, 2024) Gallego Panesso, Cristian Alexander; Almonacid Hurtado, Paula María
    This study addresses the implementation of various time series regression and machine learning models, such as: ARIMA, ARIMAX, SARIMA and Random Forests with the objective of accurately predicting the price of gold in the spot market and the USD–COP exchange rate. Precision in these predictions is crucial for export companies in the mining sector, as it allows them to establish optimal coverage ranges in the use of financial derivatives. Throughout the study, different machine learning algorithms were evaluated and compared, selecting those that provided the most accurate and consistent results. The findings offer a valuable tool for financial risk management and strategic decision making in the context of gold price volatility and exchange rate fluctuations. At the end of the study, it is indicated that the ARIMAX Rolling Forecast model applied in a parameterization (1,1,0) was the most accurate and consistent model over time for the price forecasts of both assets.
