13 Newmont BODDINGTON GOLD MINE Leica Geosystems - JigSaw Position System

14 Jassist - Positioning System Tightly Integrated GNSS+Locata Measurements in Leica s Core Algorithm Library (CAL). Co-located GNSS and Locata antennas. Well-aligned phase centres Multipath mitigating reception patterns

15 Boddington Gold Mine Current Network North Pit Current Depth: 250m 140 kms (90 miles) SE of Perth Planned Depth: 850m 4 Semi-permanent LocataLite sites 12 mobile trailers South Pit Current Depth: 300m

16 Boddington Gold Mine JPS Performance Accuracy vs GNSS only Horizontal Difference Vertical Difference

17 Boddington Gold Mine JPS Performance - Typical availability over 1 week North Pit GPS only North Pit With Locata GNSS only 75.3% Availability GNSS+Locata 99.5% Availability Began running 2 JPS receivers in April 2012 on 2 production drill rigs. Newmont now mandated all high-precision machines in mine must be fitted with Locata
