Golden Minerals Co (AUMN) CEO Resignation; Board Appoints David H. Watkins

What Happened

• Golden Minerals Company (AUMN) filed an 8-K on Sept 10, 2026 reporting that President and CEO Pablo Castanos notified the company on Sept 4, 2026 that he will resign as CEO effective Sept 30, 2026. Castanos will remain on the Board and his resignation was not due to any disagreement with the company.
• The Board appointed long-time director David H. Watkins (age 81) as President and Chief Executive Officer effective Sept 30, 2026. Watkins has served on the Golden Minerals board since March 2009 and has over 50 years’ experience in mining and exploration.

Key Details

• Resignation notice dated: Sept 4, 2026; effective date: Sept 30, 2026.
• New CEO: David H. Watkins — director since March 2009; extensive senior roles at Atna Resources, Cyprus Amax, and other mining companies; holds B.A. and M.S. in Geology.
• Compensation and employment terms: No employment agreement or compensation has been determined; the company will file an amendment to the 8-K if material terms are set.
• The company issued a press release on Sept 4, 2026 regarding these changes (furnished as Exhibit 99.1 under Regulation FD disclosure).

Why It Matters

• Management leadership changes can affect company strategy, operational focus and investor confidence. Golden Minerals is transitioning from an external CEO to an internal long-serving director with deep mining experience.
• There is no immediate change to director composition (both Castanos and Watkins will remain on the Board), and no material compensation details have been announced yet — investors should watch for the amendment disclosing any compensation arrangements and for any further operational updates tied to the new CEO.
