CHRIS MONTEIRO

Delivering weekly Grade Control models using Conditional Simulation for multiple mining areas and structurally controlled gold orebodies. Supporting Resource Model updates and MRE reporting under QP oversight. Interpreting structural controls including shearing, veining and structurally controlled mineralisation across multiple pits. Supporting short- and long-term planning through geological interpretation, model outputs and budget development. Integrating Grade Control modelling with mining requirements and production workflows.

Performed geostatistical analysis and estimation for Grade Control models, including compositing, variography, KNA, Ordinary Kriging and Inverse Distance estimation, with model validation using swath plots and global bias analysis. Interpreted geological, geochemical and structural controls on mineralisation and developed/maintained wireframes for fault, PFM and PAF domains. Applied drill-spacing and geological confidence criteria to assess model confidence and support mining decisions.

Applied QA/QC, drill-spacing studies and geological confidence criteria to support Measured, Indicated and Inferred resource classification and annual Resource updates. Performed geometallurgical domain validation and statistical analysis to support resource confidence and reporting. Developing 2WP and 3MP ore delivery targets for pit-to-port, aligning with engineering, planning, and port constraints. 

Performing geological stope assessments and modeling, stope reconciliation and stope inspections. Designing a stope re-development program that contributes to the definition, implementation & monitoring of short, medium and long-term mine exploration programs to Extend the Life of Mine (LOM) and increase reserves and resources at Mount Isa Mines, Mount Isa. 

Assist in the generation of high-quality grade control and resource models by performing data validations. Reconciled Resource Models against Grade Control and production data, investigated model-to-mine variances and supported technical validation of geological assumptions. Assisting  external consultants for technical reviews on orebody knowledge and validations.

Project planning and target generation that contributed towards adding to the site's Reserve and Resource base through discovery, extension, and delineation of high-value gold deposits that meet the company’s strategic objectives at Frogs Legs, Kalgoorlie. 

Interpreting and analyzing the results of drilling and other geological and geotechnical information to delineate current and future exploration targets, and support evaluations of ore reserves/resources to effect efficient mining operations at Hope Downs, Pilbara. 

Monitoring post-mining operations for rehabilitation purposes at Western Coalfields, NSW. UAV based evaluation and spatial distribution of land degradation at Ivanhoe, NSW.
