IWT SENTINEL™: DATA ANALYTICS - MINING FOR DATA

• Increase business intelligence and drive KPI’s !

• Productivity is enhanced through capture and analysis of operational data !

• Operational improvement requires the data to be: – Useful: the right information – Accurate: reliable information – Consumable: easily understood – Actionable: easy to act on !

• Capture – Data integrity is a must to be useful – Auto capture whenever possible !!

• IWT Goal: • Enable accurate data capture for customers to run their operations more

efficiently, with improved safety and better cost effectiveness.

IWT SENTINEL™: TESTIMONIALS

• Arch – • “Best communications apparatus we have seen, it exceeded

our expectations” & “the technology used today will revolutionize mine rescue” !

• CONSOL Energy – • “If I could replace my current C&T system today with this I would do

it. Best comms/coverage we have seen even against other wireless (vs. leaky feeder) systems.”

• “Having clear voice communications between the command center and the active team underground is a game changer” and “If it isn’t easy to use, we don’t want it”. Note - Deployed to support CONSOL MERD without notice to mine personnel. Teams went “wireless” with 3 minutes of training.

!• Alpha –

• “Best system on the market, high quality product and low maintenance/support cost. IWT is an innovator who is setting a new benchmark for C&T in mining.”

!• Rosebud –

• “Superior system we have used for 4+ years in 25 of our mines. IWT is a great company to work with, stands behind its products and has a strong service/support network.”

!• MetInvest –

• “IWT SENTINELTM extends our communications coverage area; it’s a lot faster and it may reduce our set up time by 50%”

IWT SENTINEL™: MINE OPERATION CHALLENGES

• Challenging market with tight capital equipment budgets !

• Increasing # of disparate networks to be managed – Communications

– Tracking !

• Increased regulation and compliance support – Higher soft costs = maintenance, sustainment and support expenses

!• High “hard cost” of quality, replacement & maintenance of C&T systems

– Leaky feeder cable, amps and troubleshooting be compliant – Tracking devices are throw away/disposable – 4x cost impact for wiring alone, miles of underground cable – 2x Voice and 2x Tracking

!• Continuous improvement of operational efficiency a must

– Achieve lowest production costs to overcome market price fluctuations

– Predictable and low life cycle management and compliance costs

2x increase in Cu since ‘09
