[{"type":"text","content":" VANCOUVER, CANADA / ACCESSWIRE / June 6, 2020 / Aztec Minerals Corp. (TSXV:AZT) (OTCQB:AZZTF) announces that data inversion and interpretation of a recently completed NSAMT geophysical survey (natural-source audio-frequency magneto-telluric) has identified strong conductive bodies underlying the Company's Tombstone silver-gold-copper-lead-zinc property in southeastern Arizona. Such conductive bodies can be related to buried sulfide mineralization such as CRD polymetallic high-grade massive sulphide drilled by Santa Fe Mining in 1989. Host rocks to the historic silver mines at Tombstone were primarily clastic sediments of the Cretaceous Bisbee Formation. Below around 200 meters (m) in depth, the Bisbee is underlain by the same Paleozoic limestone formations that host the massive Taylor CRD zinc-lead-silver deposit located 60 km southwest of Tombstone. Taylor was discovered by Arizona Mining in 2015 who accepted a takeover bid from South32 in 2018. (view Tombstone Map - Location, Regional Geology, and Mines here). The 4-line, 7.1 km AMT geophysical survey data was put through an inversion model and interpreted into 4 horizontal depth slices (depth slices) at 1,200 m, 1,000 m, 800 m, and 600 m elevations above sea level (asl). However, the town of Tombstone is at the 1385 m elevation so the depth slices are approximately 400, 600 and 800 m below surface. East-west pseudo-sections (pseudo-sections) were also generated for each line across the property down to the 500 m elevation. Aztec CEO, President and Chief Geologist Joey Wilkins commented, \"On the 1200 m depth slice (Depth-slice-1200m), a series of 3 resistivity highs (conductive lows) mark the major north-south trending structure underlying the Contention pit. We interpret this feature to be related to the alteration, silicification and intrusive dikes associated with the epithermal gold-silver mineralization mined at Contention.\" \"A strong conductive body west of the mid-pit appears to be related to a small intrusion with surrounding incipient hornfels and skarn alteration on surface. This is the exactly the geological environment we want to see for potential CRD massive sulfide mineralization in the underlying Paleozoic limestone sequence. A weak conductive body immediately east of the north-pit may indicate the potential for more epithermal mineralization in an area neve...
