 A fundamentally differentiated contribution to existing explosive products

 No shock combined with high energy delivery, classified as 1,4S

 Cartridge products suitable for all borehole sizes from 9mm – 87mm across power

charges from 3g – 1.7kg

 Significant factors influencing adoption include:

─ Classification: Benefits from 1,4S accreditation in transport, storage and use

─ Legislation shifts: No mass detonation hazard or malicious application favors non-

explosive solutions in sensitive blasting and/or built-up areas

─ Productivity: Avoided shock means minimal scatter rock, no site downtime,

immediate re-entry

─ Cost effectiveness: Lower than the cost of a detonator

─ Safety: 1,4s accredited. No deflagration without confinement. World’s first safety

switch in Gen III

 More appropriate solution for certain rock breaking applications

 Turkey, 2017 - present

 Marble stone quarrying where the shockwave from conventional explosives would otherwise compromise the value of the marble

 Traditional methods include mechanical pecking as well as diamond wire cutting, but no high explosive use is permissible by quarrying management due to degradation of stone

 Bench heights range from 4m to 10m

 AutoStem use in Turkey set to change the economics of marble stone industry globally due to radically reduced recover costs of AutoStem vs. traditional mining methods

 Advantages of using AutoStem over conventional alternatives include:

— Site safety

— No shockwave damage to high value stone and minimal vibration

— Very low cost relative to conventional pecker methods of stone removal or diamond cutting wire

 USA, California, 2017 - present

 High explosive use in road side blasting in built up areas create numerous challenges, infrastructure-damage risks and safety implications

 Particularly in high-traffic areas, conventional explosives will typically cause significant road-way congestion and disruption

 Underground infrastructure (piping, etc) and overhead power lines risks being compromised by conventional blasting due to shockwaves, fly-rock and high vibration

— Site safety

— No interruption to vehicular traffic flow, allowing for blasting on an as-you-need-to basis.

— No risk at all to nearby infrastructure or utilities due to shockwave or fly-rock

 AutoStem, since 2016, has been used in the safe removal of hardened concrete in concrete mixers and storage drums, large boulders in crushers and tree trunk blasting

 Our 9mm (3g, 6g and 9g) products cause no damage to drum or mixer equipment, and is safely used in basement removal settings, pillar or concrete beam removal

 10mm boreholes can be drilled with an electric hand- held Hilti-drill (or equivalent), requiring no compressed air or other power sources

 No equivalent solution to the AutoStem micro-range exists in the hydraulic breaker or explosive sector today

 USA and Europe, 2016 - present

 High explosive use presents vibration damage risk, noise pollution, safety risks and permitting challenges

 More and more, in-city regulators reluctant to permit explosive use in built up areas

 Per high explosives are permitted, time-of-day restrictions slow down site development adding substantially to development costs

 AutoStem products eliminate these limitations allowing for any-time blasting, elimination of noise, site safety and administrative ease

— Site safety, elimination of detonators, administrative ease

 In the above comparison, 10kg of conventional packaged explosive product was compared to 4.6kg of AutoStem product

 The conventional packaged explosive achieved an advance of only 1.2m with significant vibration at 10m and 22m. Re-entry was permitted after 2 hours to allow for ventilation of dust

 In the AutoStem blast, no sequential firing was required for an advance of 1.4m. Vibration was 66% less in comparison and no ventilation was required with an immediate re-entry.

 High explosive use invariably causes harm and risk to sea/ocean/river life, which is entirely avoided by use of AutoStem products

 AutoStem products are effortless to use in comparison to conventional explosives particularly in difficult underwater applications

— No environmental concern arising from risk to sea life (due to avoided shockwave

— Ease of use as well as general user safety

— No requirement to evacuate ships, barges and other infrastructure due to avoided shockwave

A G L O B A L M A R K E T

 Global use of AutoStem continues to expand with a brand presence on every continent

 The application range of AutoStem products continues to expand as blasters integrate AutoStem products into applications previously blasted with conventional explosives

 AutoStem competes directly with the hydraulic breaker market. For example, inclusion of AutoStem in the Spokane (Washington) tender of 2018, reduced the cost of a conventional hydraulic breaker solution by 53%

 The global explosive market is estimated at US$22 billion per annum with packaged explosives constituting 40% of that market. Mining accounts for 75% of these economics
