The U/Th ratio highlights variations between uranium and thorium abundances within the survey area and supports interpretation of lithological variations and alteration patterns.

The underlying survey data were microlevled and interpolated to produce seamless 200 m grids prior to ratio calculation. The final raster was delivered as a .ers file in NB Stereographic double (NAD83).</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>
