Gold Grain Counts from Surficial Sediment Samples from Alberta (tabular data, tab-delimited format)

This digital data release includes gold grain counts from 874 surficial sediment samples collected across Alberta. The surficial sediment samples include: 423 stream sediment samples, 417 glacial till samples, 21 glaciofluvial sediment samples, 8 lacustrine sediment samples, 4 diamicton samples, and 1 pre-glacial sand sample.

The bulk glacial till and stream sediment samples were collected in 2022 and 2023 as part of the regional till and stream sediment sampling program funded by the Mineral Grant provided by the Government of Alberta. The program focused on three general areas in Alberta (southwestern, north-central, and northwestern) to support the evaluation of critical mineral potential in the province.

The archived sample fractions represent preserved fractions from surficial sediment samples collected across northern Alberta in the 1990s that were previously analyzed for kimberlite indicator minerals (KIMs). With the primary focus of past programs on KIMs, the fractions from individual samples were recombined and reprocessed for gold grains.
