ABOUT US
Committed to continued innovation in blasting technology
We are the global leaders in the research, development and commercialization of alternative explosive technology offering a safer, environmentally friendly and more cost-effective replacement for explosives.
Our research and development team remains unmatched, having developed the world-patented, novel self-stemming technology and the safety switch in AutoStem Generation III.
Primary and Secondary Blasting System | Integrates any Centralized Blasting System | Sequential Ignition | Continuous Blasting Cycle | Self-Stemming | Non-Detonating | No Airblast | Low Vibration | No Overbreak | Controlled Fly Rock | Decreased Danger Area | No Noxious Emissions | No Evacuation Of Personal and Equipment Necessary | No Explosive Registered Delivery Vehicle Required
AUTOSTEM MEETS INTERNATIONAL SAFETY REQUIREMENTS
ALL AUTOSTEM PRODUCTS ARE ACCREDITED AND ENDORSED FOR USE BY ALL MAJOR EXPLOSIVE REGULATORY BODIES GLOBALLY.
HIGH PERFORMANCE, SELF-STEMMING, NON-DETONATING CARTRIDGES
Self-Stemming. Safety Switch Technology. Gen III Booster. Auto Sequential.
Power
AutoStem delivers twice the power than conventional high explosives so less is required.
Transportation
AutoStem does not require special vehicles with security escorts for transportation, and storage is simplified.
Manufacturing
AutoStem production processes are more simplified, greener and less expensive.
Safety
Using AutoStem does not require clearing of equipment and personnel for more than 50m and in a mining environment re-entry is immediate.
Accessories
AutoStem products do not require expensive accessories such as detonators, which also does away with the requirement for strict stock control and inventory of these products.
Storage
Shelf-life of AutoStem is years, so if not used immediately it is not wasted – explosive are months.

Energy content
2.0 x more powerful than the next best packaged explosive at 5,121 j/g energy capacity
Speed of deflagration
340 m/s – Ensuring minimal vibration impact to surrounding environment
Pressure
500 MPa – With reaction runaway, AutoStem Cartridges reach maximum pressure within milliseconds sufficient to break out the hardest rock
Density
1.1 g/cm3 – Highest packing and mix density makes Gen III Cartridges the most powerful blasting cartridge available worldwide
Vibration
PPV reduction relative to conventional explosives by up to 90% (depending on cartridge size, rock competency and application type)
Water resistant
Water resistant as a standard to a depth of 50m (6 bar)
SUMMARY TECHNICAL INFORMATION
AUTOSTEM VS. CONVENTIONAL EXPLOSIVES
66% reduction in vibration using Gen III
4.8kg of AutoStem used versus 10.0kg of conventional packaged explosives for a 1.2m advance, 90% reduction in dust, and vibration at 6m, 12m and 18m markedly reduced. Immediate re-entry possible with no toxic gas concentration
