Results of field works using the controlled source radiomagnetotelluric sounding method on a site in the Yakutia kimberlite province are considered. Kimbertite pipes on this site are covered with terrigeneous sediments of 60-80 m thickness. The possibility of mapping the roof of kimberlite hosting carbonate rocks and studying the structure of the overlying strata were shown. The information on the detailed separation and correlation of terrigenous sediments covering pipes can be used for the study of redeposited residual soils, containing buried aureoles of diamond accessory minerals, and the interpretation of data of mineralogical methods for searching kimberlites.
