Neita Concession, Candelones Project, Restauración, Dominican Republic; Au deposit. Main achievement: Timely completion of the Feasibility Study for the Candelones Oxide Project, an open pit heap leach gold mine project. Responsibilities include: Working together with the COO to complete the Feasibility Study of the Candelones Oxide Project in time. Close interaction with geological, mine planning, metallurgical, geotechnical, and construction consultants and contractors to define the project parameters in the context of the feasibility study, in preparation for the detailed engineering study, and further for the construction activities. Prepare simple financial models for the capital and operational costs of the construction of the mine to estimate project costs. Create timelines for the oxide project execution and the next phase of the concession (Candelones Sulfides project). Review and reorganization of all existing exploration data of the Neita Concession. Planning of the next drilling program at the Candelones Extension orebody to increase and upgrade the mineral resources of this deposit, which is part of the second phase of the development plan of the Candelones Project.

Minera Media Luna, Media Luna Project, Guerrero State, Mexico; a Au-Cu-Ag skarn deposit. Main achievement: Reduction of time and money invested to complete the first stage of the Infill Drilling Program. The program upgraded inferred resources of the Media Luna deposit to indicated category by drilling 165 diamond drill holes. To complete this drilling program in time and budget alternative drilling methods had to be evaluated and implemented. This included the use of wedges for corrective and directional purposes and the implementation of Directional Drilling with the Azidrill tool. The time needed to complete the infill program was reduced significantly implementing these alternative drilling methods (compared to the originally planned standard drilling). By changing the drilling methods, the cost for the drilling program was also reduced on a price per target. Responsibilities include: Leading the Exploration Team (in cross shift with Chief Geologist). Direct supervision and mentoring of up to 4 Project and 5 Junior Geologists. Analyze geochemical and geometallurgical data (in collaboration with consultants working on the feasibility study) to improve mineralogical and geological understanding of the deposit and use gained knowledge to create 3D models for mine planning. Communicating with and guide drilling contractors and external consultants involved in the feasibility study. Assist to project management with due consideration to Safety, Environment, and Community Relations. Develop and maintain procedure manuals and constantly audit executed works. Ensure proper data collection according to industrial standards. Elaborate weekly and monthly reports for senior management. The work involves the use of various software programs including Leapfrog, ioGAS, and Microsoft Office. Show less

Breakwater Resources LTD – cum Nyrstar since 08/2011 American Pacific Honduras, El Mochito Mine, Honduras; a 2000+ tpd Zn-Pb-Ag skarn deposit mined underground since 1948. Major achievements: Main responsible for the biannual Resource and Reserve Estimation of the El Mochito Mine. This task included the review and preparation of the drill hole database, the creation of new and update of existing geological models, the actualization of the block model, and the application of mining parameters. Responsible for the implementation and follow up of operational improvements in the diamond drilling department. Planning and supervision of drilling campaigns. Responsibilities included (focus changed over time): Exploration: Administration of exploration projects including planning and supervision of diamond drilling and soil sampling programs. Geological field mapping. Communication with and project coordination of geophysical and geochemical consultants. Creation of a historic exploration database. Training of Junior Geologists and management of technical and field staff. Modelling: 3D geological modeling and elaboration of resource estimations according to international standards, geostatistical analysis, maintenance of databases and supervision of the QA/QC program. Production: Mine geologist responsible for core logging, ore control, face sampling, back and face mapping. Working closely with mine engineering and operation departments. Since 2010 I enjoyed a Senior position. During 2012/13 I visited other mines within the company to provide support in special projects (e.g. 3D geological modeling, geostatistic studies). All tasks involved the use of various computer software programs, mainly GEMS, but also AutoCAD, Surfer, Isatis, ArcGIS, and Microsoft Office. Show less
