Introduction:
Fire assaying is the industry-standard method for accurately determining the content of gold, silver, and platinum-group metals (PGMs) in high-grade ores. While modernized, this process has been in use for centuries due to its precision and reliability.
Fire assaying is widely used for analysing gold in various sample types, including:
✔ Drill core samples
✔ Soil samples
✔ Chip samples
This technique remains the most trusted and accurate method for assessing precious metal content in hallmarking and refining operations.
