Gold Assaying

We provide expert mineral assay services for gold, covering both exploration and ore reserve samples. At LINDENMEYR MUNROE SHIELDS, we deliver accurate, reliable, and timely assay data to clients worldwide, supporting informed decisions in gold exploration and production.

Selecting the most suitable and cost-effective assay method depends on several key factors:

  • Type of sample

  • Sample mineralogy

  • Presence of coarse gold

  • Additional elemental testing requirements

We offer a comprehensive range of techniques to meet the needs of gold explorers and miners, including:

  • Lead collection fire assay for precise gold analysis

  • Screen fire assay and accelerated cyanide leach for coarse gold deposits

  • Target generation analysis using aqua regia or BLEG

  • Partial digest geochemistry

  • Multi-element and pathfinder testing

  • Lithogeochemical packages

  • Bullion assays and on-site mine laboratories

Our structured approach ensures that every assay is performed with accuracy, efficiency, and the highest industry standards, giving clients confidence in their exploration and production strategies.

Precious Metal Assay Services

At LINDENMEYR MUNROE SHIELDS, we offer specialized fire assay services, the trusted standard for accurate and quantitative gold determination. Our carefully formulated assay fluxes are designed to maximize precious metal recovery across a wide range of mineralogical matrices.

While aqua regia digestion can process many minerals, certain silicates and refractory minerals remain largely undissolved. Aqua regia remains an effective and cost-efficient method for preliminary exploration and as a screening tool for gold and other elements.

Our team of experienced mineral assay professionals combines years of expertise in the mining and mineral industry, ensuring precise, reliable results. Contact us today to learn more about our services and how we can support your mineral evaluation needs.
