Sample Preparation:


  • The purpose of sample preparation is to produce a homogeneous sub-sample, representative of the initial material submitted by the client.
  • Taking under consideration that sample preparation is the most critical step in the entire laboratory operation, we at DAL Mining handle the sample with care to prevent any possible contamination. We also follow the standard Quality Control procedures to monitor the quality of our crushing and pulverization processes.

Onsite Analytical Services:


Under strict compliance with the Health, Safety and Environment, DAL Mining services include:


  • Design, building and management of mine site laboratories, including custom equipment design and manufacturing (benches, samplers, etc.) and installation and servicing of equipment.
  • Update and optimization of existing laboratories.

Our testing capabilities and include but not limited to: AAS, ICP-OES, ICP-MS, Advanced Microwave Digestion System, UV-visible Spectroscopy, Conductivity, pH, etc. Below is a short list of analytical packages we offer:
  • Determination of gold in rocks, ores and other geological materials by aqua regia digestion followed by atomic absorption techniques finish
  • Determination of gold and silver in geological samples by aqua regia digestion with AA finish
  • Determination of gold and multi-elements package by aqua regia digestion with ICP-OES finish

Our Internal and External Quality Control Scheme:


  • The Analytical Laboratory Services of DAL Mining have a comprehensive QA/QC program to monitor and control all aspects of laboratory processes in order to provide the most reliable and defensible analytical results.
  • During the process of analysis, quality control samples, which include certified reference materials, internal control samples, procedure blanks and duplicates, are inserted in each analytical run.
  • The following summarizes the frequency QC samples processed:
    • 5% Method Blanks (MB) – one analysed within each process lot of 20 samples.
    • 10% Laboratory Duplicates (Dups) – two analysed within each process lot of 20 samples.
    • 5% Laboratory Internal Control Samples (LICS) – one analysed within each process lot of 20 samples.
    • 5% Certified Reference Samples (CRS) – one analysed within each process lot of 20 samples.
  • Dal Mining Laboratories regularly participate in international round robin programs for gold and precious metals analysis.
