Freeport Indonesia and Stania Sign Heads of Agreement for Silver and Lead Sales
Jakarta, July 11, 2025 – President Director of PT Freeport Indonesia (PTFI) Tony Wenas and Director of PT Solder Tin Andalan Indonesia (Stania) An Sudarno signed a Heads of Agreement (HoA) for the sale and purchase of lead and silver produced from PTFI's Precious Metal Refinery (PMR) facility. The signing was witnessed by Deputy Minister of Investment and Downstream Todotua Pasaribu, and President Director of PT Arsari Tambang Aryo Djojohadikusumo in Batam, Thursday, July 10, 2025.
Tony explained that in this agreement, PTFI will supply raw materials in the form of silver and lead produced from PTFI's PMR facility to Stania for solder tin production. "PTFI produces silver and also other by-products such as lead. That's what we will then supply to Stania for solder tin mixture. The quantity is approximately 10 tons of silver per year and 250 tons of lead per year," said Tony.
According to Tony, domestic demand for refined metals from PTFI is very important. "We hope domestic industries will absorb and now it's proven there is demand and we will continue to promote it. Not only PT Stania but we also hope there are others who need refined metals from us for domestic consumption, so that the downstream ecosystem related to further products and also the EV ecosystem can be quickly achieved in accordance with government expectations," said Tony.
PTFI's Precious Metal Refinery (PMR) is one of the producers of gold and silver bars in Indonesia with a refining capacity of around 50 tons of gold and 200 tons of silver per year as well as Platinum Group metals of 30 kg platinum, 375 kg palladium.
"In July, PTFI's PMR has produced silver bars. Current estimates until the end of 2025, PTFI will produce 100 tons of silver. Meanwhile, for lead production it's 2 thousand tons per year," said Tony.
Tony added that the signing of the HoA between Freeport Indonesia and Stania is a commitment to realizing domestic downstream development. Strengthening this statement, Stania Director Sudarno explained that the synergy between PTFI and Stania is an important step in realizing Indonesia's independence in the mining sector, especially in silver downstream development.
"Silver and lead are needed as alloys to produce solder tin. Stania's current need for lead is 250 tons per year. Meanwhile, at this initial point, the need for silver is 10 tons per year," said Sudarno. He said this step is in line with the government's efforts to reduce dependence on imported products and encourage the use of domestic products. "This synergy of silver and lead absorption from PTFI is Stania's commitment to strengthening business. In addition, with strengthening domestic raw material procurement, the company is not dependent on imports," said Sudarno.
In this HoA, PTFI and Stania will conduct further negotiations to establish business relations in the form of a Definitive Agreement, including conducting studies.
Through this strategic partnership, PTFI and Stania are committed to continuing to contribute to building a competitive national mining industry. Domestic downstream development is key to creating greater added value, so as to accelerate the realization of Golden Indonesia Vision. (Corporate Communications)
