Ex-Proof Mobile Phone in Timika Mining
The Grasberg mine lies in Mimika Regency, Central Papua, near Puncak Jaya, and the original mine was built at about 4,100 metres above sea level, with the open pit rim at roughly 4,270 metres. Concentrate goes by 166-kilometre slurry pipeline to the port at Amamapare, so hazardous areas include fuel, power, process plant and underground workings. This page explains what to look for in an Ex-proof mobile phone for Timika and the Grasberg mining district, and where the IS-04Z1 stands against that list today.

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 term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Timika and the Grasberg mining district. A marking check would first confirm whether an area is gas or dust, then compare zone, gas group and temperature class. Fuel storage is gas. The IS-04Z1 target marking, II 2 G Ex ib IIC T4, is unapproved and does not cover underground rules the operator may apply.

Questions · Timika Mining
Frequently asked questions
Can we buy an Ex-proof mobile phone in Timika Mining today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an Ex-proof mobile phone in Timika Mining cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Timika and the Grasberg mining district would use it?
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.
Is intrinsically safe the same as explosion proof?
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.
Do underground mines at Grasberg use block caving and what does that mean for equipment?
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.
Does the move to LNG power affect hazardous-area planning in Timika?
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.
Are underground areas at Grasberg covered by the same rules as surface plant?
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.
