Ryan has 20 years of geomechanics experience specializing in mass mining project development, strategic planning and operational support. After being stationed at the Grasberg operation, Ryan has returned to work within PT Freeport Indonesia’s corporate geotechnical group. Prior to Freeport, he worked with SRK Consulting where experience was gained in open pit and underground mass mining operations in Canada and abroad. Recent areas of focus at Freeport include optimization of cave and development sequencing, rock mass characterization, excavation design, ground control, open pit/underground interaction, fragmentation forecasting and risk management.
