Borden Mine is in the early stages of an Advanced Exploration Project

Underground mine with ramp access from surface

Mobile equipment primarily electric/battery powered Two boom jumbo, 14 ton LHD, MacLean Bolters and Service carrier, Orica emulsion

loaders

Trucking from u/g to surface will be handled with 40T diesel trucks (will convert to battery as

soon as technology is in place. Currently ahead of schedule

Safe – Simple – Green – Silent – Invisible

3 3 Eliminating Compressed Air Lines

Goldcorp and many other mining

companies have experienced serious

injuries to employees in events related to

compressed air based on the stored

energy hazard throughout the mine

workings

Borden Mine plans to eliminate this risk by

operating without compressed air lines in

the underground workings

A risk assessment is open and

active, ensuring that we identify and

mitigate all hazards

4 4

Potential concerns created by eliminating

compressed air lines underground

1. Delivery of stench gas

2. Source of emergency ‘fresh’ air in

the event of underground smoke

or ambient air contamination

Eliminating Compressed Air Lines

5 5

Without compressed air, this traditional method of

delivering stench gas in a mine emergency is

eliminated.

Notification in the Event of a Mine Emergency

Emergency notification will be accomplished by:

1. Delivering stench via the mine ventilation system

2. Voice notification via mine radio

3. Borden is investigating electronic alarm systems such as flashing cap lamps, mobile vehicle lights, radio alarm systems, etc.

Without compressed air, this traditional source of

‘fresh’ air in a mine emergency is eliminated.

Emergency ‘Fresh’ Air in a smoke or gas event

Measures to offset this condition

are:

• Portable Self Contained Refuge

Chamber

• Drager ChargeAir system

• Self Contained Breathing Apparatus

• Storage cache of SCBA units

• SCBA re-fill stations

• PAS Colt personal breathing air units

or Self Contained Self Rescuers

Fully self-contained

48 hour capacity (expandable to 72 hrs)

Inclusions – mine radio, gas monitoring, etc.

Located as per Goldcorp guidelines – example every 60m vertical

or 600m along tunnel (to be confirmed)

Portable Self Contained Refuge Chamber

8 8 Worker Protection Strategy

To accomplish this goal: Emergency hardware will be placed in

specific and key locations

Everyone going underground will be

trained in it’s use

Personnel would have immediate

access to breathing apparatus (if

required) during an event, and then

proceed to a refuge station

Goldcorp Borden Mine intends to have breathing

protection available to every person underground,

within moments of an underground event.

9 9 Drager ChargeAir system – what is it?

• System consists of:

• Self Contained Breathing Apparatus – SCBA

• SCBA Storage Cache Units

• SCBA Recharge Stations

• Proven technology

• Drager is reputable and has a long

history in emergency equipment

• System used extensively in US coal

mines

10 Drager ChargeAir system

Self Contained Breathing Apparatus (SCBA)

Fully enclosed

Highest level of respiratory

protection

Good visibility & communication

Comfortable to wear

No lifespan or shelf life – except

bottles (carbon fiber has 15yr life)

Simple use

Parallels Mine Rescue & Fire

Fighting

11 Drager ChargeAir system

SCBA Storage Cache Units

Sealed for apparatus protection

Basic unit holds 10 SCBA’s

Located 2nd or 3rd re-muck back from the face

Spacing from Refuge Chamber or Refill Station maximum 850m **

12 Drager ChargeAir – SCBA Storage Cache Units

13 Drager ChargeAir system

SCBA Recharge Station

Sealed for component protection

Good for 36 full refills

Placed in strategic locations for refilling

Spaced 850m ** max. from SCBA cache, or another refill station

14 Drager ChargeAir – SCBA Recharge Station

Emergency

Mask

Emergency masks available at each recharge station

Available if someone reaches a recharge station without an SCBA

Mask is plugged directly into recharge station

Substantial amount of air supply

15 Drager ChargeAir – SCBA Recharge Station

16 Drager ChargeAir – SCBA Recharge Station

17 Personal Protection

Personal Airline System PAS Colt

Bridge unit from face to SCBA cache unit

10 minute capacity

Similar to SCBA use

Units to be stored at SCBA Cache locations

& on mobile equipment

Personnel take one with them to the face

Hook-up availability at recharge stations

NIOSH recommends this unit for use within

100m of fresh air based on entry & escape,

and maintenance tasks

Our use dictates escape only and maximum

ramp travel distance is set at 285m **

18 Personal Protection

Self Contained Self Rescuer - Drager Oxy box K25

Personal emergency self rescuer

Bridge unit from face to SCBA cache unit

30 minute capacity (850m of travel in

ramp)**

Robust case

Relatively light unit

Personnel carry one at all times

19 PAS Colt vs Self Rescuer

Drager PASColt

PROS • Infinite shelf life

• Same training as SCBA

• Good visibility/communication

• Can be connected to

recharge station

CONS • $1,875 each

• 10 minutes of protection

• One scenario is the need to pick up & return unit to cache location each time (or could store a few in a box near the face)

20 PAS Colt vs Self Rescuer

PROS • 10 year life

• $1000 each

• 60 minutes of protection

• Strong, robust case

CONS • Require one for everyone

• Single use then useless

• Different training

• Poor visibility/communication

• Larger/heavier than Oxy K25

Drager Oxy 6000 SCSR

Drager Oxy box K25

PROS

• 5 years before service

• $850 each

• 30 minutes of protection

• Strong, robust case

• Lighter/smaller than 6000

CONS • Require one for everyone

• Single use then useless

• Different training

• Poor visibility/communication

21 21 National Institute of Occupational Safety and Health

** According to NIOSH standards, travel

distances under air are based on:

• 30 minute walk on level ground or 5,600 feet

• Assume ½ that distance in ramp or 2,800 feet

• 2,800 feet is equivalent to 853 meters

• Assume 30 minutes = 853 meters in a ramp

• Then 10 minutes = 285 meters in a ramp
