The Loza GPR survey successfully detected and mapped magnetite ore in confined structures:
fractures and displacements due to the block structure of the deposit are clearly visible on the GPR profiles the shallow dipping magnetite deposit is shown on the GPR profile as areas of physico- lithological
heterogeneities in near-surface and deeper levels (15 to 90m). According to the GPR profiles the upper boundary of the anomaly shifts to the west with depth consistent with the general dip trend of the deposit;
the estimate depth of detection of magnetite deposits with Loza GPR can reach over 100 meters four types of anomalies were detected according to the GPR data: 1) with boulder iron ore; 2) with high mineralization of water; 3) with vein-disseminated ore and mineralized wallrock serpentine, metasomatite and hydrothermally altered rocks; and 4) with rich parts of magnetite (primarily massive) ore
The results of the GPR survey on the Kruglogorski deposit show that Loza GPR can be used for preliminary prognostic evaluation of prospective magnetite mineralization at depths of over 100m and for further appraisal of flanks of known magnetite deposits.
