30 Second Briefing
Stantec has been appointed by St Augustine Gold & Copper to lead the definitive feasibility study and engineering for the US$2.37 billion Kingking copper-gold project in Pantukan, Davao de Oro, Mindanao, a major greenfield open-pit development. The mandate covers mine planning, process plant design and infrastructure for what is expected to be one of the Philippines’ largest copper-gold operations, requiring detailed geotechnical, tailings and water management solutions in a high-rainfall, seismically active setting. For contractors and consultants, the DFS will define scope for bulk earthworks, pit slope design and large-scale materials handling systems.
Technical Brief
- Stantec’s mandate spans mine planning, process plant, tailings, water management and site-wide infrastructure engineering.
- Scope includes geotechnical design for large open-pit slopes in a high-rainfall, seismically active setting.
- Engineering services will define bulk earthworks quantities and haul road geometries for large-scale materials movement.
- Tailings storage facility options must address tropical storm events, erosion control and downstream community exposure.
- Water management design will need high-capacity diversion, storage and treatment to handle intense monsoonal runoff.
- DFS outputs are expected to fix major packages for plant construction, pit development and offsite infrastructure contracts.
- For contractors, early engagement around earthworks, slope stabilisation and materials handling systems will be critical to pricing.
Our Take
Stantec’s role at the Kingking copper-gold project aligns with its growing presence in complex infrastructure and design mandates, as seen in our database entries where it also leads major water and transport design frameworks for Scottish Water and the Shetland subsea fixed link.
Within our 1102 Mining stories, copper–gold projects like Kingking tend to be among the larger capex items, signalling that St Augustine Gold & Copper is positioning this Mindanao asset in the same investment bracket as long-life, multi-decade operations rather than smaller, incremental builds.
For Mindanao-based copper and gold developments, a DFS led by an international consultant such as Stantec typically helps when seeking international project finance, as lenders often benchmark study quality and risk disclosure against work done on comparable global-scale projects in our coverage.
