The key areas subject to QA/QC auditing prior to mineral resource estimation are project-specific protocols and available sample data from QA/QC sampling and analysis. Project-specific protocols, often in the form of Standard Operations Procedures (SOPs), should be in place before any sampling commences.
This set of protocols is the first established for Canadian till sampling and analysis and represents a contribution to the GSC's Geo-mapping for Energy and Minerals (GEM) Program.

The sample preparation method often depends on the element like gold, or group of elements of interest including, major and minor elements and specialized groups of trace elements such as PGE. Following are some popular methods of sample decomposition selectively used for these special groups for use in geochemical and …
Soil sampling in mineral exploration is the process of taking soil samples from an area to determine the soil's mineral makeup. In the mining industry, these soil samples are used to help determine …
The next step after sampling protocol has been optimised is to add the quality control procedures. At this stage it is necessary to decide how many duplicates will be collected and how they are taken. ... Roden S, Smith T (2001) Sampling and analysis protocols and their role in mineral exploration and new resource development. In: …
Because of the altered nature of the till due to soil formation and the possibility that 'soil' samples may include other glacial or non-glacial sediment types, 'B-horizon soil sampling' regardless of the substrate (Fig. 9a–c) is not recommended for mineral exploration or publicly funded surveys.
Soil geochemical survey data are used in multiple industries including mineral exploration or environmental investigations. The scale of a geochemical survey may be relatively localized, regional, or at a national level depending on the study objectives. ... The NASGLP established common sampling protocols to ensure …
For Canadian companies, and for holders of title to mineral properties in Canada, all exploration work must be designed and carried out under the …
Soil color is an easily observed property, related to soil composition, and it would appear intuitively obvious that it would be wise to collect material of the same color, if possible, at all sites on a soil grid. Soil color and similar obvious differences in composition can be important indicators of variations in metal content.
