Melonjaknya laba bersih itu disebabkan tingginya harga jual rata-rata logam timah serta lebih besarnya volume produksi dan penjualan logam timah, demikian siaran pers yang diterima Antara di Jakarta, Kamis.
The net profit increase was attributed to higher average selling price of refined tin as well as higher production and sales volumes of refined tin, PT Timah said here on Thursday.
