Uranium values are obtained from gamma-ray spectrometry measurements and reflect near-surface lithology and alteration patterns.

The final raster was projected to NB Stereographic double (NAD83) and delivered as individual grid.</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>
