Thorium values are derived from gamma-ray spectrometry measurements and reflect near-surface lithology and alteration patterns within the survey area. The dataset is provided in NB Stereographic double (NAD83) for consistent integration with provincial datasets.</SPAN></SPAN></P><P><SPAN STYLE="font-size:16pt"><SPAN>The NBWesternBorder_Th raster was produced by microlevelling line-to-line variations in the original survey data and interpolating the results to a seamless 1000 m grid. The final raster was delivered as a .ers file in NB Stereographic double (NAD83).</SPAN></SPAN></P><P><SPAN>The dataset is not updated regularly. Updates occur only if new reprocessing, corrections, or additional surveys become available. As of now, the compilation represents the most recent processing as of December 2025.</SPAN></P></DIV></DIV></DIV> |
