52 Attachment 2 – Mine Access Tunnels Predictive Risk Based Assessment Zones are identified to reflect the grouting effort required based on anticipated inflows to tunnel: - Zone 1 Low inflow (seepage) Q <10L/min 2 probe holes ahead of tunnel face advancement (as required) - Zone 2 Moderate inflow 10 <Q< 20L/min 4 probe holes. Remedial grouting may or may not be required - Zone 3 High inflow 20 <Q< 100L/min 4 probe holes. Remedial grouting required - Zone 3B Very high inflow Q >100L/min 4 or more probe holes. Such zones have yet to be identified but may be present within the ore body. Significant redial grouting likely required
