| ABSTRACT: | Toronto, Canada… Seabridge Gold announced today that its search for large new porphyry targets within the KSM Mining District has identified four prospects with signatures matching the established deposits where reserves and resources have been delineated. These new targets (see map) are under the Sulphurets Thrust Fault (STF) and are therefore ‘blind’, unlike the known deposits which were exposed at surface by erosion. Ongoing exploration at KSM since 2005 has recognized the potential for undiscovered porphyry deposits west of the exposed deposits and below the STF system. Criteria were selected to limit the search to the most prospective and realistic targets based on our extensive knowledge of the known deposits: (1) Strong magnetic susceptibilities associated with potassic alteration at depth and low susceptibilities for shallow phyllic altered shells: (2) Proximity to deep east-west trending, steeply-dipping structures reflected in magnetics: (3) Distinct high resistivity features coincident with deep, sodic-calcic altered, sulfide depleted sub-porphyry cores contrasting with low resistivity in adjacent and capping sulfide-rich shells; (4) Proximity to the Sulphurets Thrust Fault which tracks the TriassicJurassic regional unconformity in the KSM district; and (5) High induced chargeability effects in variable geometries related to high pyrite content in surrounding hornfels and skarns with overprinted phyllic shells. Deep penetrating geophysical techniques were employed in 2019 to improve resolution on targets and generate discrete zones for testing in the future. New Z-Tipper Axis Electromagnetic (ZTEM) surveys and 3D IP surveys were completed. Data was integrated into a digital 3D earth model by Mira Geoscience. These results are now being integrated with historical MT surveys, airborne high-resolution magnetic survey, bore hole geophysical surveys and geological mapping. Geophysical profiles indicate that these targets can be tested from surface but would likely be evaluated as bulk underground opportunities. | |
