PRODUCTS

Quincy Materials produces high-value, market-ready materials recovered from legacy mining tailings — delivering critical minerals for U.S. industry and low-carbon materials for modern construction.

Our products are engineered to meet rigorous performance standards, support domestic supply chains, and deliver measurable environmental benefits at commercial scale.

High-Purity Copper Concentrate

Copper is essential to electrification, renewable energy, transportation, data infrastructure, and national defense. Quincy Materials recovers copper from historic tailings using proven beneficiation and separation technologies — converting a long-standing environmental liability into a strategic domestic resource.

Key Attributes

  • Recovered from legacy copper-bearing stamp sands

  • Produced using established industrial mineral processing methods

  • Suitable for downstream refining and smelting

  • Supports U.S. supply chain resilience and import reduction

Critical Metal for a Modern Economy

  • Electrical wiring and transmission

  • Renewable energy systems

  • Transportation and electric vehicles

  • Infrastructure and defense applications

QuinCEM™ 2.0

Next-Generation Supplementary Cementitious Material (SCM)

QuinCEM™ 2.0 is a finely ground, basalt-derived Supplementary Cementitious Material engineered for modern concrete applications. Produced without combustion or chemical activation, QuinCEM delivers high performance with a dramatically reduced carbon footprint.

    • Natural pozzolanic activity

    • Alkali-Silica Reaction (ASR) mitigation

    • Improved compressive strength and durability

    • Consistent particle size and mineralogy

    • Independent testing confirms:

      • Strength Activity Index (SAI) ≥85

      • ≥75% strength at 20% cement replacement (ASTM benchmark)

      • Compatibility with ready-mix and blended cement systems

    • Replaces a portion of carbon-intensive Portland cement

    • Avoids combustion-based SCM processing

    • Each ton of cement replaced avoids ~0.8 tons of CO₂

    • Ready-mix concrete

    • Precast and prestressed concrete

    • Infrastructure and transportation projects

    • Low-carbon and high-durability construction

Future Product Streams

Quincy Materials’ platform is designed for expansion as additional mineral streams are characterized and commercialized.Together, we outline a path forward that’s realistic, strategic, and tailored to your specific needs.

Potential Future Products Include

  • Metal and mineral fractions

  • Engineered fine aggregates

  • Specialty mineral blends for construction and industrial use

Each product stream is evaluated through a rigorous process of materials characterization, performance testing, and market validation.

Built for Scale

Our products are developed using proven industrial technologies and scalable processing methods, enabling repeatable deployment across multiple legacy mining sites.

  • Planned commercial facilities designed for 200+ TPH throughput

  • Logistics optimized for rail, truck, and Great Lakes shipping
