5. Case Study of Mt. Milligan PorphyryBy Dianne Mitchinson and Nigel Phillips5.1. Summary of Results Presented at Roundup WorkshopTerrane Metals Ltd. contributed 12,541 measurements from 180 boreholes along with geologicaldescriptions and corresponding 2D and 3D models. Samples were measured every 1 to 2 metersdown each borehole. From this data and local geophysical surveys an analysis was done of theapplication of magnetic susceptibility. The recommended steps of analysis are summarized alongwith representative illustrations.Step 1 – Assemble Local and Regional Magnetic Surveys. High resolution surveys
