Remote highland site
Grasberg sits at about 4,100 metres elevation, and Timika's Mozes Kilangin airport handles domestic flights and interior routes.
Timika, capital of Mimika Regency in Central Papua, is the service base for the Grasberg copper and gold mine run by PT Freeport Indonesia. Concentrate goes by 166-kilometre slurry pipeline to the port at Amamapare, so hazardous areas include fuel, power, process plant and underground workings. If you are specifying an ATEX and IECEx mobile phone for Timika and the Grasberg mining district, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Timika and the Grasberg mining district: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Timika Mining. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Grasberg sits at about 4,100 metres elevation, and Timika's Mozes Kilangin airport handles domestic flights and interior routes.
Grasberg has three active underground mines (Grasberg Block Cave, Deep Mill Level Zone and Big Gossan) alongside the former open pit.
Flotation reagents separate a copper-gold concentrate, which is piped as slurry through three pipelines about 100 km to the port of Amamapare, where it is dewatered, dried and shipped to smelters.
The port facilities include a coal-fired power station that is to be replaced by 2027 with a 265 megawatt liquefied natural gas combined cycle plant, which will add an LNG supply chain to the site.
Grasberg held proven and probable reserves of 14.0 million tonnes of copper, 808 tonnes of gold and 3,773 tonnes of silver at the end of 2022, so mining is expected to continue for decades.
PT Freeport Indonesia runs Grasberg, with Indonesian state interests through MIND ID holding 51.23 percent and Freeport-McMoRan 48.77 percent, and mining rights were extended to 2041.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Timika and the Grasberg mining district. A reviewer at Grasberg or Timika would expect certificate evidence matched to the marking, with its schedule of conditions. The IS-04Z1 evidence is in progress. A dual ATEX and IECEx route helps a large operation whose contractors and suppliers come from many countries.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are concentrator and process plant, fuel storage and distribution, concentrate port and dewatering, underground mine areas. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Grasberg has block-cave and other underground operations with large ore flows and ventilation. Equipment in underground areas typically needs the approvals the operator specifies, and the mine controls access, so ask for its underground device and communications requirements.
A planned 265 MW LNG-fired plant by 2027 would add natural gas storage and handling near the port, which sites usually classify as hazardous areas. Check with the operator for updated classification drawings if you will work near new power facilities.
Not necessarily. Underground mines have their own classification and approval rules set by the operator. A device accepted at the concentrator may not be accepted underground. Ask the operator's central safety team about each area.
