Blackstone Minerals Unlocks Mankayan Copper-Gold Potential with SPP and Strategic Backing

How Blackstone Plans to Use the Funds Raised Through Placement and SPP
Blackstone Minerals Limited has announced that proceeds from its recent A$22.6 million Placement and up to A$2 million Share Purchase Plan (SPP) will support the next phase of development at its flagship Mankayan Copper-Gold Project in the Philippines—one of Southeast Asia’s most promising undeveloped copper-gold systems.
Planned Use of Funds
According to the company’s announcement, capital will be allocated to:
- 50,000m Drilling Program – Launching in July with two rigs, expected to deliver consistent news flow.
- Geophysics and Field Work – Including IP surveys, magnetics, and exploration follow-up.
- Metallurgical and Geotechnical Work – Key to development strategy and feasibility.
- Working Capital and Offer Costs – Supporting ongoing corporate and operational activities.
Mankayan: A Tier-1 Copper-Gold Asset with Global Significance
Blackstone reports that Mankayan is among the largest undeveloped porphyry systems globally:
- JORC Resource: 793Mt @ 0.65% CuEq 9.7Moz gold, 2.8Mt copper, 20.4Moz silver
- High-Grade Core: 170Mt @ 0.93% CuEq, potentially enabling early-stage development
- Mining Lease: Granted through to 2046
Strategic Location: Proximity to Major Discoveries
The Mankayan project is situated on the same tectonic belt as tier-1 discoveries like Grasberg (Indonesia), Escondida (Chile), and Cadia (Australia). Additional highlights:
- Surrounded by 12+ porphyry targets within a 10km radius
- Adjacent to the FSE porphyry (891.7Mt @ 0.7g/t Au & 0.5% Cu)
- Strong upside from district-scale development and infrastructure sharing
Operating in a Proven Mining Jurisdiction
The Philippines is recognised for its long history of successful mining operations:
- Notable operations include B2Gold and OceanaGold
- 25-year Mineral Production Sharing Agreement (MPSA) renewed in March 2022
- Blackstone, through its merger with IDM International, holds an established social licence to operate
Global Demand Drivers for Copper and Gold
Copper: Supply Crunch Meets Rising Demand
Copper is positioned for sustained long-term growth due to:
- Historically low global inventories
- Underinvestment in new supply and project delays
- Demand from electrification, data centres, and green infrastructure
- Goldman Sachs’ outlook: copper could surpass US$15,000/tonne
Gold: The Hedge of Choice
Forecasts remain bullish due to:
- Ongoing central bank buying
- Geopolitical instability and inflation concerns
- Weak USD boosting demand
- Goldman Sachs predicts: gold could rise to US$3,700/oz by end of 2025
