Potassium values are obtained from gamma-ray spectrometry measurements and reflect near-surface lithology and alteration patterns. The dataset is provided in NB Stereographic double (NAD83) for consistent province-wide coverage.</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:0 0 0 0;"><SPAN>The potassium grid was produced by compiling individual NRCan radiometric survey grids, microlevelling line-to-line variations, and interpolating the results to a seamless 200 m grid. 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>
