A – distribution <strong>of</strong> <strong>the</strong> assigned permeabilities; B – distribution <strong>of</strong> temperature; C – Darcy fluxes andvectors; D – distribution <strong>of</strong> <strong>the</strong> tracer. A, B, and D show fluid flow lines. The red box in (C) outlines <strong>the</strong> area <strong>of</strong> <strong>the</strong> maximal fluid flow that is pertinent for all <strong>the</strong> subsequentfigures. The model does not represent <strong>the</strong> present-day hydrogeological regime in areas proximal to <strong>the</strong> Four Mile and Beverley deposits.Page 90 <strong>of</strong> 151
