Aztec Minerals Acquires Late 1980’s-Early 1990’s Drilling and Trenching Data
for the Tombstone Project, Arizona
Historic Drill Results Include 1.61 gpt Gold, 91.2 gpt Silver over 44.2 meters, and
32 gpt Silver, 0.61% Copper, 6.5% Zinc, 2.6% Lead over 7.2 meters,
Historic Trench Results Include 8.15 gpt Gold, 386 gpt Silver over 9.45 meters,
and 74.6 gpt Gold, 3,135 gpt Silver over 1.83 meters
Vancouver, Canada – September 18, 2018 - Aztec Minerals Corp. (AZT: TSX-V) announces it has acquired
late 1980’s-early 1990’s drilling and trenching data for the Tombstone project in Arizona. Aztec holds an
option to acquire a 75% interest from Baroyeca Gold & Silver Inc. in most of the old patented claims (163
hectares) constituting the famous Tombstone silver mining district located 100 km southeast of Tucson,
Arizona.
Historic drilling by USMX totalled 7,350 meters in 86 reverse circulation drill holes primarily around the
old Contention mine open pit in 1993. MPV Capital drilled another 1,867 meters in 14 holes in 1994.
Aztec reviewed the USMX and MPV reports, located the drill collars for the USMX holes, and the general
areas of the MPV drill collars (gravel mining since the 1990’s has disturbed some areas).
Highlights of the USMX drilling include 1.61 grams per tonne (gpt) gold and 91.2 gpt silver over 44.2
meters (m) length in hole TR-001 and 1.42 gpt gold and 28.6 gpt silver over 68.58 m in hole TR-002. The
Contention mine open pit-heap leach mine operated from 1980 to 1985, and intermittently from 1986
to 1989, exploiting shallow, bulk tonnage, epithermal gold-silver stock-work mineralization around the
Contention dike and fault. The Contention Mine is within the Tombstone Property under option from
Baroyeca Gold. USMX drill highlights are shown in the table below and drill hole true widths of
mineralization were not provided nor interpreted.

Historic drilling by Santa Fe Pacific between 1988 and 1990 targeted deeper (below 200 m) carbonate
replacement deposits (CRD) in the Paleozoic limestones underling the Bisbee Group sandstones that host
most of the historic silver mines and veins in the Tombstone district. Aztec reviewed the Santa Fe reports
and located the drill collars for the Santa Fe drill holes.
Highlights of the Santa Fe drilling include high grade, massive sulfide intercepts related to both carbonate
replacement deposits (CRD), skarn, and manto mineralization such as 32 gpt silver, 0.61% c opper, 6.5%
lead, 2.6% zinc over 7.2 m in hole T-8 and 2,407 gpt silver, 0.8% lead and 1.1% zinc over 0.3 m in hole T-1.
Santa Fe drill highlights are shown in the table below. True widths of these intercepts were not provided
nor interpreted from the Santa Fe drill hole data.

Historic trenching by Cowichan Mines Ltd. in 1989 in the pit floor at the south end of the Contention mine
open pit totalled 12 sample lines over an 85 m length. Aztec reviewed their report but was not able to
locate the trenches because the south pit is covered by shallow fill related to recent gravel mining.
Highlights of the Cowichan trenching include 8.15 gpt gold and 386 gpt silver over 9.45 meters in trench
10200N and 74.56 gpt gold and 3,135 gpt silver over 1.83 meters in trench 10075N. There are no records
of any drilling in the area of the south Contention open pit , highlights in the table below. True widths of
mineralization from the trench data was not provided in the historic reports.

Joey Wilkins, President and CEO of Aztec commented, “These historic drill and trench results give us a
great head start on defining high priority targets for future drilling, and a solid foundation to work from
going forward at Tombstone. Our Phase 1 exploration program now underway of detailed mapping,
sampling, airborne magnetic survey and machine trenching should help to refine our targeting.”
“The USMX and Cowichan data clearly show significant epithermal mineralization remains to be drilled
around the old Contention mine open pit and the Santa Fe holes intersected high grade massive sulfide
mineralization in the west part of the district quite distal from more optimal structural locations for CRD
mineralization based on our work to date.”
Historic production in the Tombstone district from 1878 to 1939 was estimated at 32 million ounces (oz)
silver and 240,000 oz of gold from several small vein and manto CRD deposits. Aztec management views
the district as highly prospective for the discovery of both near surface, epithermal gold-silver and
deeper, silver-gold-copper-lead-zinc carbonate replacement deposits.
The Tombstone district is underlain by the s ame Paleozoic limestone formations that host the massive
Taylor zinc -silver-lead deposit of Ariz ona Mining Inc. , located only 65 kilometers west of Tombstone .
Arizona Mining Corp and shareholders have accepted a friendly $1.8-billion takeover bid by South32 on
August 1 0, 2018 . Similarly, the Bisbee porphyry copper -gold complex 33.5 kilometers southeast of
Tombstone contained impressiv e copper -silver-gold CRD deposits in the same Paleozoic limestone
formations as Tombstone.
