Overview
Orica is an Australian-based multinational focused on products and services used in mining, quarrying, construction, tunnelling, oil and gas, and related infrastructure activities. It is best known as one of the world's major suppliers of commercial explosives and blasting systems, but its portfolio also includes initiation systems, bulk and packaged explosives, blasting data and analytics, ground-support technologies, seismic systems, and sodium cyanide used in gold extraction. The company serves surface and underground mines, construction contractors, quarries and other industrial customers across more than 100 countries. The business traces its origins to Jones, Scott and Co, established in 1874 to supply explosives during Victoria's gold-rush era. The enterprise was later acquired by Nobel Industries, which became part of Imperial Chemical Industries through a series of chemical-industry mergers. Imperial Chemical Industries of Australia and New Zealand was incorporated in 1928 to coordinate the group's Australasian interests. The Australian operation became independent in 1997 after Imperial Chemical Industries sold its controlling interest. Because the former ICI Australia name could no longer be retained, the company adopted the Orica name in February 1998. Orica subsequently reshaped itself around mining and industrial services. It separated Dulux in 2010, reducing its exposure to consumer and building coatings, and sold its chemicals business to Blackstone in 2014–2015. That divested business became Ixom. The transactions left Orica more concentrated on blasting, mining chemicals and specialist technologies rather than operating as a broad chemicals conglomerate. Acquisitions have expanded its technology and geographic capabilities. GroundProbe, a provider of slope-stability monitoring and measurement systems for mining, joined the group in 2018. Orica acquired Essa, an industrial explosives business in Peru, in 2020, and acquired Terra Insights and Cyanco in 2023. These transactions strengthened its position in geotechnical monitoring, sample-preparation and explosives activities, as well as sodium cyanide supply for gold processing. Orica's commercial proposition combines consumable products with engineering, field services, automation, measurement and technical support. Its blasting offering includes contracted services, electronic and other initiation systems, boosters, bulk explosives, packaged explosives, seismic systems and data-driven reporting. Its cyanide business supports gold producers with sodium cyanide, analyzers, sparging equipment, technical services and training. The company has also marketed technologies intended to improve blast outcomes, productivity, safety and environmental performance. Orica remains an ASX-listed company headquartered in Melbourne. It has historically reported a workforce of approximately 15,000 employees and contractors. Its public profile has been shaped both by its role as a critical supplier to the global resources sector and by scrutiny of environmental incidents, industrial accidents and safety practices at Australian and overseas facilities. The company publishes sustainability reporting and has been associated with sustainability benchmarks including the Dow Jones Sustainability Index, the Australian SAM Sustainability Index and FTSE4Good. Orica House in East Melbourne, a prominent historic headquarters building, reflects the company's long industrial history in Australia.
History
Orica began in 1874 as Jones, Scott and Co, an explosives supplier serving the Victorian gold rush. It was later acquired by Nobel Industries. Nobel subsequently became part of Imperial Chemical Industries, and the Australasian operations were coordinated through Imperial Chemical Industries of Australia and New Zealand, incorporated in 1928. The Australian company became independent in July 1997 when Imperial Chemical Industries sold its 62.4 percent interest. Because the ICI Australia name was no longer available, the company was renamed Orica on 2 February 1998. The new identity marked the transition from an Australasian arm of a British chemical group to an independent public company with a strong regional industrial heritage. During the following decade Orica repositioned its portfolio toward mining and industrial services. Dulux was separated in 2010. The chemicals division was sold to Blackstone in November 2014, with the transaction completed in March 2015; the divested operation became Ixom. Orica consequently focused more clearly on commercial blasting, mining chemicals, ground support and related technologies. The company expanded through technology and geographic acquisitions. GroundProbe joined Orica in 2018, adding monitoring systems used to identify movement and stability risks in mining environments. Essa was acquired in 2020, strengthening the company's explosives presence in Peru. In 2023, Orica acquired Terra Insights and Cyanco, broadening its monitoring and measurement portfolio and its sodium-cyanide business. Orica's history has also included significant environmental and safety controversies. A series of incidents at Australian plants in 2011 involved releases or spills of hexavalent chromium, arsenic, mercury, ammonia, ammonium nitrate and sulphuric acid. These events produced public criticism, investigations, regulatory action and temporary operational restrictions. The company also faced scrutiny over groundwater contamination associated with historic chlorinated-solvent production at Botany, New South Wales, where it built a groundwater treatment plant. In Mexico, an explosives-transport accident in 2007 caused multiple fatalities and injuries. In 2015, chief executive Ian Smith departed after a bullying controversy. Today Orica is headquartered in East Melbourne and operates internationally as a specialist supplier to the resources, construction and infrastructure sectors. Its model combines physical products with technical services, automation, analytics, monitoring and customer-site support. The company reports sustainability performance and has been included in sustainability-related investment indexes, while continuing to manage the environmental, safety and regulatory responsibilities associated with explosives and industrial chemicals.

Products and positioning
A global mining-services and blasting-technology specialist combining explosives, field engineering, digital blast optimization, geotechnical monitoring and mining chemicals.
Mining and construction blasting
Commercial explosives and blasting systems
Orica supplies bulk and packaged explosives, boosters, initiation systems and related blasting services for surface mining, underground mining, quarrying, construction, tunnelling, oil and gas and infrastructure projects. The offering is supported by blast design, field execution, reporting, analytics and supplementary technical services intended to improve fragmentation, productivity, safety and control of blasting outcomes.
Mining technology
Digital blasting, data and seismic systems
Orica's technology services collect and analyze information about blast performance and ground response. These systems support planning, measurement, reporting and optimization, while seismic capabilities help customers understand blast effects and manage operational risks in mining and construction environments.
Gold-processing chemicals
Sodium cyanide solutions
Orica supplies sodium cyanide used in gold extraction and provides associated technical capabilities. The offering includes cyanide handling and sparging solutions, analyzers, data and reporting, professional services and training for customers operating gold-processing facilities.
Geotechnical monitoring · 2018
GroundProbe monitoring technologies
GroundProbe technologies monitor movement and stability in mining environments, particularly slopes and other geotechnical structures. Integrated measurement and reporting help operators identify changing conditions and support decisions concerning mine safety, productivity and asset management.
Ground support
Minova ground-support products
Historical Orica offerings associated with Minova included steel and polymer bolts, plates, mesh, resin capsules, injectable chemicals, foams, grouts, coatings, pumps, anchoring systems and engineering services. Minova is no longer part of the Orica Group, so these products should not be treated as current Orica offerings.
