Updated on Nov. 6, 2026 in Public Companies
On March 13, 2025, the board of Medellin-based gold miner Mineros S.A. authorized directors and management to buy or sell Mineros shares in the market. The authorization, announced March 14, 2025, runs seven calendar days and concludes March 20, 2025.
Why it matters
The authorization was granted in the context of the Amended Sun Valley Offer, a relevant corporate transaction affecting the company's shareholder base. The board conditioned the approval on the absence of privileged information held by any board or management member.
The board's authorization covers a seven-calendar-day trading window ending March 20, 2025, as recorded in Minute No. 583. The filing does not disclose whether any insider intends to buy or sell during that window.
