Blackstone Minerals Limited (ASX: BSX) has confirmed a major leadership change following the resignation of its Managing Director, Scott Williamson. The Company said Mr Williamson will step down from his role on 31 January 2026.
The update is the centre of current market attention around the Blackstone Minerals MD resignation, which marks a key shift for the ASX-listed copper and gold explorer. The Company operates in the Philippines through its Mankayan Copper-Gold Project, one of its most strategic development assets.
Blackstone Minerals Limited stated that the transition will be managed through interim executive leadership while a permanent replacement is appointed. The announcement is considered material for shareholders given the Company’s growth-stage Project portfolio.
Blackstone Minerals board changes confirmed
Following the Blackstone Minerals MD resignation, the board has acted to ensure leadership stability. The Company has appointed current Non-Executive Director Geoff Gilmour as Executive Chairman with immediate effect.
Mr Gilmour will take on executive responsibilities while the board runs a formal recruitment process for a new Chief Executive Officer or Managing Director.

In addition, Blackstone Minerals Limited has strengthened its board by appointing Greg Cunnold as a Non-Executive Director. Mr Cunnold is a geologist with direct experience at the Mankayan Copper-Gold Project.
The board stated that his appointment enhances technical oversight during the transition period.
Leadership transition and management comments
The board acknowledged the contribution of the outgoing Managing Director.
“The Board thanks Mr Williamson for his contribution to the Company during his tenure and wishes him well in his future endeavours,” the Company said.
The appointment of Mr Gilmour is intended to provide continuity as operational and corporate activities continue.
“Mr Gilmour will perform an executive leadership role while the Board undertakes a process to identify and appoint a replacement,” the Company confirmed.
The Blackstone Minerals board changes come at a time when the Company is working to advance its flagship Philippine asset.
Strategic importance of the Mankayan project
Blackstone Minerals Limited holds interests in the Mankayan Copper-Gold Project in the Philippines. The Project is considered a large-scale development opportunity within a region known for porphyry copper-gold systems.
Copper remains a core metal for global electrification and renewable energy growth. Gold continues to provide revenue diversification and price stability for mining groups.
Mr Cunnold’s experience at Mankayan is expected to support ongoing technical and development decisions. His background in geology and Project evaluation is considered valuable as Blackstone Minerals Limited moves through its leadership change.
Market and industry context
The Blackstone Minerals MD resignation occurs against a backdrop of rising global interest in copper assets. Copper demand is driven by electric vehicles, renewable energy, and grid upgrades.
The Philippines remains one of Asia’s major copper-gold jurisdictions. Its proximity to Chinese and Southeast Asian markets gives miners logistical and supply chain advantages.
Companies operating in the region also benefit from access to established mining infrastructure and skilled labour. Blackstone Minerals Limited continues to position itself within this competitive landscape.
Leadership continuity is seen as important for maintaining Project momentum and investor confidence.
