[{"type":"text","content":"Aztec Reviews Geological Highlights of Phase 1 RC Drill Program from Tombstone Project, ArizonaVANCOUVER, BC / ACCESSWIRE / January 12, 2021 / Aztec Minerals Corp. (TSXV:AZT)(OTCQB:AZZTF) reviews the geological highlights of the recently completed Phase 1, reverse circulation (RC) drill program conducted at the Tombstone project in Southeastern Arizona from August to November 2020.The Phase 1, 21-hole, 2,993 meter drill program tested the potential for shallow, broad, bulk tonnage gold-silver mineralization around and below the Contention open pit and underground mine workings. The Contention Mine was historically the largest and highest grade silver mine in the Tombstone silver district (32 million oz past production) in the late 1800's-early 1900's. More recent Contention open pit mining in the early to mid-1980's focused on gold-silver mineralization to approximately 60m depth entirely hosted within the Cretaceous Bisbee group sandstones. Most other mines in the district were much smaller veins and mantos hosted within the lower Bisbee and partially within the underlying Paleozoic limestones.Three drill centers, North, Central, and South, were drilled along the Contention open pit in spoke patterns to minimize the amount of road building and maximize the potential to intersect mineralization. The main Contention structures that host the mineralization trends north-south and dips vertical to steeply west.Coherent, widespread gold-silver mineralization associated with narrow, porphyritic felsic dikes was consistently intersected in 18 of 19 drill holes along the main Contention structure and parallel structures over an 800 meter strike length. The mineralized structures cut through outcropping Cretaceous Bisbee sediments to around 200 meters in depth where they cross an unconformity down into the underlying Paleozoic limestones. As such, management believes the Bisbee sediments and Contention mineralization are contained within a circular, down-dropped graben fault bounded basin.View: Tombstone Longitudinal Section and Tombstone 2020 RC Drill Program Plan Map Higher-grade intervals include 6.18 grams per tonne (gpt) gold and 77.2 gpt silver, or 7.15 gpt gold equivalent (using an 80:1 silver:gold ratio), over 15.14 metres (m) in hole TR20-09 and 4.18 gpt gold plus 174.2 gpt silver, or 6.36 gpt gold equivalent, over 7.62 m in hol...
