China issues new rules for export management of silver
The Transformation of Design Possibilities
China has issued new rules for the export management of silver, which include a quota system for qualified companies for 2026-2027. This follows a period where quota management for silver exports had been suspended.
The new rules, announced by the Chinese Ministry of Commerce (MOFCOM) on October 30, 2025, aim to “step up the protection of resources and the environment, and enhance the export management” of rare metals including silver, tungsten, and antimony.
Quota System: Export quotas have been reintroduced for silver and certain other rare metals.
Eligibility: The rules specify requirements for domestic manufacturers and traders applying for export qualifications, including criteria related to credit loan quotas and export levels from 2022-2024.
Goal: The measure is intended to ensure only qualified and responsible companies are granted export rights and to strengthen state control over strategic resources.

Rio Tinto’s Diamond Division Posts $79 Million EBITDA Loss in 2025
Higher output from Canada’s Diavik Diamond Mine offsets revenue decline, but end-of-life pressures continue to weigh on performance.
Rio Tinto reported a challenging year for its diamond business in 2025, posting an underlying EBITDA loss of $79 million despite improved revenues. While the loss narrowed compared to the $115 million deficit recorded in 2024, the division remained under pressure amid a global diamond market slowdown and the nearing closure of its last active mine.
Annual revenue rose 19% to $332 million, supported by stronger production at the Diavik mine in Canada, Rio Tinto’s only remaining diamond operation. Output climbed 61% to 4.4 million carats, driven by the ramp-up of mining activities in the underground section of the A21 deposit, which began scaling up in late 2024.
However, the A21 underground ore body is expected to be depleted by the end of the first quarter of 2026, marking the end of Diavik’s operational life. The company plans to spend approximately $1 billion this year on closure activities related to Diavik, as well as rehabilitation work at the former Argyle Diamond Mine, which ceased production in 2020, and other non-diamond projects.
