Helping safeguard miners in over 40 countries, across six continents, the MineARC MineSAFE Series is the world s most trusted refuge chamber in metal (hard rock) and non-metal mines. Emergency refuge forms an integral part of an underground mine s wider Emergency Response Plan (ERP). Fires, explosions, rock-falls, flooding, and the release of smoke and other forms of toxic gas are the types of incidents that occur all too frequently, despite the high levels of planning and the safety precautions in place. In these types of emergencies, when evacuation is nolonger safe or practical, emergency refuge is designed to provide a safe and secure go-to area for personnel to gather and await extraction. MineARC Refuges have been successfully used around the world in multiple mine and tunnelling emergencies to save lives. Refuge chambers should be deployed throughout the mine to create a refuge 'network' accessible to all underground personnel whilst on foot. Depending on the country/region, regulations usually state acceptable 'safe distances' between refuge chambers. MS-CD1-04-ELVP-36 3

Standard Configurations In consultation with the world s leading mining companies and regional mining authorities, the MineARC MineSAFE Range has been continuously re-engineered and refined to create a safe-refuge alternative that is fully integrated with today s modern underground mining environment. The MineSAFE Compact Design (CD) is designed specifically for tight mining confines, such as single-entry development headings. This small, compact, ultra-portable refuge chamber is easy to manoeuvre and position around site. The Compact Design is designed for optimum autonomy. The chamber s extra-low-voltage control system means it can sit stand-alone for extended periods without requiring connection to mains (mine) power (around 6 weeks). MS-CD1-04-ELVP-36 4 Person, Standard Model Ultimately a MineSAFE CD's dimensions and its rated occupancy can be custom-engineered to site specifications, without compromising on safety or performance. Standard configurations are based on 4, 6 and 8 person occupancies, with a range of optional features.

INTERIOR LIGHTING 8watt fluorescent Inside a MineSAFE Compact Design Refuge Chamber, a number of vital life support systems combine to create a safe, ongoing environment for occupants. Systems include primary and secondary oxygen supplies, air conditioning systems, positive pressure systems, electrical systems, gas detection and CO/ CO2 absorption systems (referred to as scrubbing systems). The MineSAFE Compact Design uses active chemicals and MineARC's ELVP (extra-low-voltage-portable) Scrubbing System to scrub the build up of harmful CO2 (carbon dioxide) and CO (carbon monoxide) from the air inside the refuge chamber. AIR (OXYGEN) SUPPLY #1: COMPRESSED MINE AIR Low pressure air supply (120psi; 830kPa) In high enough concentrations, both CO2 and CO can cause serious injury leading to a loss of consciousness and eventually death. CO2 and CO are expired by the occupants as part of their normal breathing activity. Carbon monoxide can also enter the main chamber via the compressed air intake (if it becomes compromised), and as occupants enter and/ or exit the main entrance, making CO/CO2 scrubbing a vital necessity. Air Conditioning Air conditioning is vital to combat the potentially fatal effects of heat stress caused by a build up in occupant s own metabolic activity, as well as any ambient (external) heat affecting the refuge chamber s internal temperature. Extra-Low-Voltage Controller Interface The controller interface is the operational hub of the refuge chamber. From here all power, lighting and scrubbing systems can be managed with the flick of a switch. MARCISORB Chemical Cartridges AURA-FX DIGITAL GAS MONITOR The ELVP Scrubbing System uses pre-packaged MARCISORB chemical absorber cartridges. MineARC s MARCISORB CO and MARCISORB CO2 cartridges provide superior scrubbing capacity, are easy to load, safe to handle, and can store for long periods. 7

GuardIAN enables real-time monitoring; providing confidence that an operation s fleet of refuge chambers are emergency ready at all times. GuardIAN is an on-board system that continuously monitors all vital refuge operating systems. During standby mode GuardIAN checks for component faults and monitors refuge chamber usage or entry to the chamber. GuardIAN's secure online interface is hosted on an internal server within the refuge chamber so that no client software installation is required. The responsive webpage is easily accessible from any computer, tablet or smartphone and features a summary of your entire refuge chamber fleet and overall operational status, with the ability to drill down to a detailed report of each chamber. GuardIAN is an optional upgrade for the MineSAFE Compact Design.

MineARC System Intelligence Aura-FX Digital Gas Monitoring Diagnostics MineARC's new Aura-FX Digital Gas Monitoring System is a proprietary fixed gas monitoring unit, designed specifically for use in MineARC refuge chambers and safe havens. A vast improvement on current digital gas monitors (DGMs) on the market, Aura-FX provides a refuge chamber specific solution to gas monitoring. Aura-FX has the ability to individually monitor up to 11 gases via a series of user-friendly, digital screens. Audible voice alarms will prompt occupants to replace scrubbing chemicals or adjust oxygen supply levels in the refuge chamber as required. When utilised as part of the MineARC System Intelligence network, Aura-FX provides real-time gas monitoring data and analysis via the GuardIAN dashboard. GuardIAN System Monitoring, Event Logging and Fault Diagnostics Aura-FX-CM (Compact Model) is a standard feature of the MineSAFE Compact Design and can monitor three gases at any one time. MineARC's Digital Controller links directly to GuardIAN, streaming realtime system data to a surface control room(s). Data includes automated system checks, battery fault logging, system diagnostics, internal and external temperature measurements, and system actions such as scrubber activation. System faults, events and scheduled service notifications can be sent to designated personnel as email alerts; notifying them of upcoming service requirements, potential emergencies or mal-use as they occur. GuardIAN Live Video Monitoring and VOIP Video Phone Live video streaming can greatly assist in evacuation planning during an emergency; providing the capability to determine the capacity of the refuge chamber and monitor the well-being of occupants. Internal video monitoring is provided by a remote controlled, motion activated GuardIAN IP camera. When activated, the camera will send out a live, recorded stream of the interior of the refuge chamber. External video monitoring is also available as an optional upgrade to the GuardIAN System. To assist occupants during an emergency or safety drill, GuardIAN also equips your refuge chamber with a VOIP video phone. This facilitates face-to-face communication between the refuge chamber and the surface; improving the psychological well-being of chamber occupants during an emergency, providing assistance to perform any difficult or technical procedures and facilitating face-to-face trouble shooting for service staff in order to reduce the need for multiple surface visits during a maintenance run. Compressed Air Management System Diagnostics The MineARC Compressed Air Management System (CAMS) is a dedicated air management unit designed specifically for use in refuge chambers. The unique air management system monitors and regulates compressed air flow into the chamber. When utilised as part of the MineARC System Intelligence network, vital information relating to the integrity of the internal refuge chamber atmosphere is communicated in real-time via the GuardIAN dashboard. An increase in CAMS activity would indicate a breach of the refuge chamber seal, thus sending an alert to designated personnel that the chamber is compromised. CAMS is a standard feature of the MineSAFE Compact Design. 9

Chamber Exterior Rear The rear of a MineSAFE Compact Design Refuge Chamber houses important air filtration, electrical and backup power supply systems. A secure cabinet at the base houses the refuge chamber s UPS battery back up (Uninterruptible Power Supply). The UPS is a failsafe system that can power the refuge chamber s internal life support systems for a minimum of 36hrs, should mine power become cut-off. The Compact Design's unique dual UPS battery bank configuration enables the chamber to sit standalone from mains power for extended durations. When on standby the refuge chamber s external strobe lights and siren will still operate, alerting personnel to the refuge chamber s position. When the chamber is used in an emergency situation, the primary battery bank is activated; powering the refuge chamber s entire life support systems for a minimum of 36 hours. LIFTING LUGS TRANSFORMER (Optional) CAMS FIRE EXTINGUISHER Optional for non-australian orders. Supplied separately as Dangerous Goods SIDE ESCAPE HATCH AIR CONDITIONING CONDENSER FORKLIFT SLOTS BATTERY UPS 36hr emergency backup power supply Further options available for up to 72hrs MS-CD1-04-ELVP-36 The CAMS air pressure sensor and a shut off valve allow air flow into the chamber to be regulated, automatically emitting periodic bursts of compressed air into the refuge chamber when the pressure inside drops below 200Pa. This process optimises mine air usage and guarantees against over-pressurisation of the refuge chamber. Over a 12 month period this can equate to significant financial savings. The system's gas toxicity monitor automatically diverts mine air if oxygen levels in the airline fall below a set level (19% oxygen in free air), signifying air contamination. Additionally, the incorporated flood protection valve automatically shuts down mine air to avoid catastrophic damage due to ingress of water into the mine air or accidental hook-up to mine water. 10 MineARC Systems
