15 Years Remaining: PT Timah Tbk Reports 800,000 Tonnes of Total Tin Resources

PT Timah Tbk (TINS) has recorded a total tin resource of 800,000 tonnes, with reserves amounting to 300,000 tonnes. However, this reserve volume is projected to support the company’s production operational needs for only the next 10 to 15 years.

Ilhamsyah Mahendra, Director of Production and Commercial at TINS, explained that the company is currently pushing exploration activities to secure long-term resource availability. He emphasised that adding new reserves is a priority to ensure the company’s business continuity.

“From exploration, we are now conducting truly aggressive exploration. This is one of PT Timah’s main focuses. We need to secure resource and reserve deposits. Currently, we have approximately 800,000 for resources and around 300,000 for reserves. And we need a longer mine life,” he stated during the Indonesia Critical Minerals Conference & Expo 2026 in Jakarta, as reported on Thursday (4/6/2026).

The company considers the current availability of reserves to be less than ideal compared to its vision of dominating the global market over the long term. To accelerate the discovery of new reserve points, the issuer—a member of the MIND ID mining industry holding company—has begun relying on digital mapping technology and aerial monitoring within its concession areas.

“I believe those figures are only for 10-15 years. We need far more deposits for more than a hundred years. Therefore, we are supported by various technologies for exploration activities; we use GIS platforms and drone monitoring to increase exploration accuracy and speed,” he added.

On the other hand, the company is also looking at opportunities for overseas expansion to find strategic mining assets. This strategy is being adopted so that the company does not rely solely on domestic resources, while simultaneously strengthening Indonesia’s bargaining position in the global critical minerals supply chain.

“We are now seeking global expansion, not only expanding capacity on the refining side, but we are looking for mining assets outside of Indonesia, and we are very open to seeking opportunities for partnerships and collaborations with global tin companies,” he concluded.
