[{"type":"text","content":"Aztec Minerals Confirms Five CRD Target Areas on the Tombstone Property, Arizona by 3-D Modelling of Recent Airborne Magnetic Survey DataVANCOUVER, CA / ACCESSWIRE / March 27, 2019 / Aztec Minerals Corp.(AZT: TSX-V, OTCQB: AZZTF) confirms the identification of five prospective, buried CRD target areas on the Tombstone Property, Cochise County, Arizona, USA by 3-D modelling of Aztec's recent airborne magnetic survey data.3-dimensional modelling of the airborne magnetic data was undertaken by geophysical consultants CompGeoInc of Vancouver, BC who produced a UBC modeled inversion as well as multiple depth and horizontal slices (link1, link 2). This modelling work is very useful inidentifying subsurface massive sulphide CRD (Carbonate ReplacementDeposits) targets or other styles of sulfide mineralization.Aztec previously identified three target areas based on its recent geological mapping and sampling and analysis of historic exploration and mining data. The new 3-dimensional magnetic modelling confirmed and better defined the potential of the three target areas and identified two more, as follows: The north-northeast trending Contention Pit area veins and dikes are marked by a linear magnetic high/low contact and appear to extend below the historic mines, which typically bottomed at the water table around 200 metres depth, down into the underlying Paleozoic limestone formations which are similar rocks that host the Taylor zinc-silver-lead CRD deposit of Arizona Mining Inc., subsequently purchased by South32 (located only 65 kilometres west of Tombstone). A possible south extension of the Contention Pit area, offset 100 meters to the west by a southeast trending cross fault or anticlinal structure A parallel zone to the Contention Pit approximately 350 meters to the southeast that is mostly covered by thin alluvium thus not explored in historic times, also marked by a linear north-northeast magnetic high/low contact Two northwest-southeast trending anticlinal structures, marked by a series of weak magnetic highs, host silver-lead-zinc replacements in the Bisbee Group and appear to extend into the underlying Paleozoic limestone formations A circular magnetic high with a central low occurs at the northern end of the Contention Pit, possibly separate from the dikes and veins, and could represent a pipe-like feature related to limeston...
