Provincia De Santiago, Chile

Collaborated on a numerical modeling aimed to study the slope stability of an open pit mine in northern Chile. To model the groundwater flow, constructed hydrogeological cross-sections of the advancement of the pit per year using the SEEP/W software (Geoslope).

Conducted a pilot test in the Atacama Desert of Chile to assess the usefulness of OreHound® gas passive collectors as an exploration technique in areas dominated by post-mineral overburden.Used R and MATLAB to:• Manage and analyze data, perfom thorough data quality control and quality assurance (QA/QC) analysis• Execute univariate and multivariate EDA methods to identify data populations, background and anomalies.• Run geochemical transects to study analyte concentrations with distance, identify patterns and visualize data populations in depth.• Conducted Principal Component Analysis (PCA), Factor Analysis (FA) and Cluster Analysis to investigate key interactions and patterns; and Ordinary Cokriging to interpolate analyte concentrations spatially.• Core logged a section comprised of 4,500 meters diamond core and 500 meters reverse circulation drilling.• Organized and implemented the installation and removal of gas collectors in the field. Prepared samples for laboratory analysis.• Combined soil gas insights, geology and known gas transport mechanisms knowledge to make meaningful data interpretations.• Authored a graduate thesis entitled ‘Gas-Transported Elements as an Exploration Technique under Post-Mineral Cover: Atlántida Deposit and Surroundings’.• Presentated technical results to teachers and students.• Attended a geochemistry course led by Scott Halley, attending an in-field course for core logging led by Richard Sillitoe and Scott Halley, and participating in a lithocap surface mapping campaign in northern Chile.

Santiago, Chile

Instructed students in the basic visual identification of minerals and alteration rocks through hand samples.

Chile

Internship II. Conducted fieldwork in base metals. Explored greenfield projects in the Miocene metallogenic belt of Northern Chile by mapping the geological surface of two different area projects and logging diamantine drillcores. Integrated field and drillhole data to produce geological sections and interpreted seismic data to identify target generation maps. Utilized reflectance spectroscopy analysis by Terraspec to identify minerals.

Santiago, Chile

Performed research and created a geochronology database. Utilized GIS to obtain coordinates by georeferencing.

Chile

Internship I. Worked closely with geologists on multiple projects in Northern and Central Chile. Lifted old drillcore surface data, collected and mapped cuttings. Mapped surface and logged drillcores to finally interpret the geological data at different targets.
