Jul 2020 - Present
Responsible for managing and leading training and consulting projects in mining exploration for the development and discovery of new mineral deposits through the application of various techniques such as Geological Mapping, Remote Sensing (processing of multispectral and hyperspectral satellite images), Multi-element Geochemistry (2D, 3D, EDA, lithogeochemistry, rock, stream sediment and soil geochemical sampling), Geophysics, Spectral Geology (reflectance spectroscopy for mineral vectorization), Geostatistics, Structural Geology, Machine Learning, among others. Training and consulting services primarily provided in Latin America and Canada. Since May 2022, I have been in charge of developing research projects focused on improving conventional exploration methods (geology, geophysics, geochemistry, remote sensing, spectral geology, structural geology, geostatistics, economic geology, socio-environmental aspects) and developing new non-conventional exploration methods through the application of machine learning and supervised and unsupervised multivariate analysis for the determination of new exploration targets associated with porphyry, high and low sulfidation epithermal, VMS, IOCG and New Economic Minerals Deposits (NEM) such as rare earths (REE), cobalt (Co), copper (Cu), nickel (Ni), and uranium (U).Research projects developed:-Assessment of New Economic Minerals (NEM) Potential in the North West province, Queensland - Australia.-Application of conventional and non-conventional exploration methods for the discovery of new mineral deposits in the Plateu Region of the Yukon state, Canada.In addition, several trainings have been carried out on the management of geological, geochemical, geostatistical, geophysical, remote sensing, spectral data, mineral deposits, and exploration tools for exploration geologists throughout Latin America.

Geologist specialized in copper porphyry deposits with emphasis on research, metallogeny, and recognition of vein types for mineral vectorization. Conducted geological logging activities for diamond drilling of Cu-Mo porphyry systems (Santo Tomás Project) and Skarn systems (Brasiles Project) in Sinaloa - Mexico, with over 30,000 meters logged, sampling and QA/QC of diamond drilling, measurements taken from ASD TerraSpec Halo to define mineralogical alteration assemblages and obtain spectral indices for mineral vectorization towards mineralized centers. Interpreted regional and drilling geophysical data (chargeability, electrical resistivity, and gamma ray), exploratory data analysis (EDA) and geostatistical analysis of geochemical data for geochemical modeling. Additionally, conducted geological modeling (lithology, hydrothermal alteration, mineral zone, and structure), and supervised the logging and sampling team. Technical reports developed and presented for the Exploration department, reporting directly to the Exploration Manager, Exploration President, and Qualified Person (QP). Research projects developed: -The Santo Tomas Project, Sinaloa and Chihuahua Mexico: A Particularly Elongated Porphyry Copper Deposit. Show less
