Production and Development

Mining activity remains active across the region through artisanal and small-scale mining (ASM) operations, which represent a significant portion of current mineral output.

• The broader eastern DRC region produces several thousand tonnes of cassiterite annually, with Maniema Province contributing approximately 3,000–4,000 tonnes per year .
• Additional production includes columbite–tantalite (coltan) and wolframite (tungsten) from alluvial and near-surface deposits
• Mining is primarily focused on:
  • Alluvial cassiterite
  • Coltan (Nb–Ta)
  • Wolframite (W)

           Ongoing artisanal production confirms:

•      Continuity of mineralization across the belt
•      Economic viability at current market conditions
•     Wide distribution of mineralized material
•  

Historical Dumps & Reprocessing Potential

Extensive historical mining has resulted in the accumulation of mine dumps, tailings, and partially processed gravels across the project areas.

These materials:

• Were processed using historically low-efficiency methods
• Retain recoverable quantities of cassiterite and associated minerals
• Are accessible and suitable for modern reprocessing techniques

      PKMSA recognizes these materials as an important component of its development strategy.

 

ASM Reprocessing Opportunity

Current artisanal operations typically recover only a portion of the contained minerals, resulting in the loss of fine and unrecovered material.

PKMSA aims to enhance recovery through:

• Application of modern gravity concentration techniques
• Processing of tailings and stockpiled material
•  Improved recovery of fine cassiterite and columbite–tantalite

   This approach provides a low-capital, near-term production pathway, while improving overall resource efficiency and reducing               environmental impact.

Alluvial Deposits

• Typical grades: 0.5 – 1.5 kg/m³ SnO₂
• Shallow and laterally extensive
• Suitable for mechanized and artisanal mining
•  

Primary Deposits

• Hosted in pegmatites, quartz veins, and greisen systems
• Associated with granitic intrusions
• Contain Sn–Ta–Nb–W polymetallic mineralization
•  

Development Approach

      PKMSA’s strategy integrates historical knowledge with modern techniques to unlock value across multiple resource types:

• Optimization of existing artisanal mining areas
• Reprocessing of historical dumps and tailings
• Expansion of mechanized alluvial operations
• Evaluation and development of primary deposits

     This phased approach supports efficient resource development and sustainable long-term growth.

Revenue Potential

PKMSA’s project areas offer a unique opportunity to generate revenue through a combination of existing artisanal production, reprocessing of historical materials, and ongoing resource development.

Near-Term Production (ASM & Reprocessing)

Ongoing artisanal mining across the region demonstrates active production of cassiterite, coltan, and wolframite, with Maniema Province contributing approximately 3,000–4,000 tonnes of cassiterite annually.

PKMSA’s approach focuses on enhancing this existing production base by:

• Formalizing and optimizing artisanal mining zones
• Improving recovery through modern processing methods
• Reprocessing historical dumps and tailings containing recoverable minerals

      This creates an opportunity for:

•  Immediate production
•  Low capital entry
•  Improved recovery and value realization
•  

Value from Dumps & Tailings

Historical mining operations have left behind significant volumes of partially processed material, which often contain unrecovered mineral fractions due to inefficient historical methods.

By applying modern techniques, PKMSA can:

• Recover fine cassiterite and heavy minerals
• Increase overall recovery efficiency
• Generate additional revenue without primary mining costs

      These materials represent a low-risk, high-efficiency production opportunity.

Medium-Term Growth

      Expansion of mechanized alluvial mining will enable:

• Increased production volumes
• Improved operational efficiency
• Consistent supply of mineral concentrates

      This phase builds on existing mining activity while scaling production capacity.

Long-Term Value Creation

     Primary hard rock deposits associated with granitic systems offer:

• Large-scale resource potential
• Multi-commodity revenue streams (Sn, Ta, Nb, W)
• Opportunities for long-term mine development
•  

Strategic Advantage

PKMSA’s assets benefit from a multi-layered revenue model:

1. Scalable production through mechanized alluvial operations

2.Long-term growth from primary resource development
