ANFO.jpg
JOHNEX ANFO is a free flowing mixture of porous prilled Ammonium Nitrate and Fuel Oil, formulated to be oxygen balanced for use in dry blastholes.
Megadrive_product.PNG
MEGADRIVE® cartridged emulsion explosives are a detonator sensitive, emulsified AN-based explosive specifically formulated for use in surface or underground rock blasting operations.
IED.png
JOHNEX INSTANTANEOUS ELECTRIC DETONATORS contain a priming composition of RDX base charge inside a cylindrical aluminium alloy shell, with red and grey lead wires and have been designed for use in the mining industry.
mighty_atom.png
JOHNEX MIGHTY ATOM is a high density 75g supersonic velocity primer consisting of pentolite which provides the ultimate in primer performance. The JOHNEX MIGHTY ATOM provides directional firing with 4 times the detonation pressure of cartridged emulsion.
stope_charge.png
JOHNEX STOPE CHARGE is a free flowing silver/grey mixture of porous prilled Ammonium Nitrate and Fuel Oil, formulated to be oxygen balanced for use in moderately wet blastholes.
MEGASplit_Joined_LR.jpg
JOHNEX MEGASPLIT® is a Pre-split watergel explosive presented in a continuous cartridge internally traced with detonating cord. Specifically designed for perimeter blasting in open pit applications.
Interdet.png
INTERDET® (inter-hole/inter-row) detonators consist of a single low strength, aluminium delay detonator, attached to a length of hollow plastic shock tube. The detonator is housed within a colour coded plastic connector block.
megaprime.png
JOHNEX MEGAPRIME is a Pentolite cast booster with a plastic protective outer shell.
MEGAGEL.jpg
MEGAGEL® cartridged water gel explosives are a detonator sensitive, AN-based explosive specifically formulated for use in surface or underground rock blasting operations.
Megadet.png
MEGADET® detonators are a series of high strength non-electric detonators with millisecond delay intervals ranging from 0 ms (instantaneous) to 1000 ms.
New-EziPrime-50-HiRes-Final.png
JOHNEX EZIPRIME provides directional firing with twice the detonating pressure of cartridge emulsion.
Echidna_Pair.png
JOHNEX ECHIDNA is a product retention device for all production charging applications. The semi-rigid spines flex and tighten upon insertion into a production hole, giving superior retention of both ANFO and emulsion.
SC_Detonators.png
SC (inter-hole/inter-row) detonators consist of a single low strength, aluminium delay detonator, attached to a length of plastic shock tube.
EZIPRIME_ProductShot_Revised.png
JOHNEX MIGHTYPRIME® is a high density supersonic velocity primer consisting of pentolite which provides the ultimate in primer performance. JOHNEX MIGHTYPRIME® provides directional firing with four times the detonating pressure of cartridged emulsion.
MS-detonators.png
MS detonators are a series of high strength nonelectric detonators with millisecond delay intervals ranging from 25 ms to 1000 ms.
MegaprimeBlade.png
JOHNEX MEGAPRIME BLADE is a high performance, easy to use alternative to traditional primers such as small diameter cartridge explosives.
