Aztec Minerals Options Historic Tombstone Silver Mining Properties in Arizona

Vancouver, Canada – December 18, 2017 - Aztec Minerals Corp. (AZT: TSX -V, OTCQB: AZZTF) (“Aztec”)

announces it has signed an option a greement with Baroyeca Gold & Silver (and its US subsidiaries

Tombstone Gold & Silver Inc. and Tombstone Resources Inc ., collectively “Baroyeca” ) to acquire a 75%

interest in a package of mineral properties (the “ Properties”) containing many of the historic silver

mining properties in the famous Tombstone mining district , Cochise County, Arizona.

The Properties include the historic Contention Mine and surrounding patented claims totalling 404 acres

(163.5 hectares) with an addit ional 24 acres (9.7 hectares) of unpatented claims .

http://www.aztecminerals.com/_resources/2-Tombstone-Land-and-Mines.jpg. Aztec can acquire the 75%

interest by spending an aggregate of CAD$1,000,000 on exploration , making an aggr egate of

CAD$100,000 in cash payments, and issuing an aggregate of 1,000,000 Aztec common shares to

Baroyeca over a 3 year period, as follows:

Exploration Expenditures Cash Payments Share Issuances

On signing $Nil $10,000 $Nil

Total $1,000,000 $100,000 1,000,000

The Tombs tone Mining District, located 65 miles southeast of Tucson, Arizona and accessed by State

Highway 80, is well known for its high grade, oxidized, carbonate replacement deposits (“CRD”) of silver-

gold-lead mineralization hosted in veins, mantos, pipes and disseminated orebodies. The original silver

discovery was in 1877 and historic production in the district from 1878 to 1939 is reported at 32 million

ounces silver from 1.5 million tons averaging 21.3 ounces per ton, 240,000 ounces gold, 65 million

pounds lead, 2.5 million pounds copper and 1.1 million pounds zinc.

Some of the richest production in the district was from the Grand Central and Contention Mines, both

located on the Baroyeca properties. Historic underground oxide ore grades in the district reportedly

averaged 26 oz per ton (“opT”), equal to 892 grams per tonne (“gpt”), silver, 0.21 opT (7.2 gpt) gold and

2.25% lead. Sporadic underground mining continued until 1980 , when open pit , heap leach mining

commenced at the Contention Pit. The Contention Pit operated until 1985 with two brief attempts to

restart the mine in the late 1980’s and early 1990 ’s. Open pit, heap leach m ine production totaled

around 1.86 million to ns, grading 1.25 opT silver and 0.02 opT gold, for metal production of

approximately 1.1 million oz silver and 20,000 oz gold. Although there are several reports about the

historic production from the district and the Baroyeca Properties, Aztec has not verified these historic

results and is not relying on them. The main source of historical information referred to herein is the

Baroyeca NI 43 -101 report on the Properties by Linda Caron dated August 23, 2011. Historical

production grades are not an indication of existing mineral resources or grades of any existing mineral

deposits.

In the 1990’s, the properties underwent two shallow RC drill programs, primarily near the Contention

Pit. USMX drilled 20,040 feet (6,108 meters) in 63 drill holes in 1993 and MPV Capital drilled 6,125 feet

(1,867 meters) in 14 holes in 1994. One of USMX’s better drill intercepts assayed 0.062 opT ( 2.1 gpt)

gold and 1.23 opT 42.2 gpt) silver over 125 feet in length in hole TR8 and on e of MPV’s better drill

intercepts returned 0.176 opT (6.0 gpt) gold and 6.39 opT (219 gpt) silver over 25 feet (7.6 meters).

Although there are several reports about the historic exploration results on the properties, Aztec has not

verified these histori c results and is not relying on them. Aztec does not have any information on the

quality assurance or quality control measures taken in connection with these historical exploration

results, or other exploration or testing details regarding these results.

The option agreement with Baroyeca remains subject to certain conditions precedent, including the

approval of the TSX Venture Exchange.

Aztec Minerals CEO Joey Wilkins commented, “ Tombstone adds a second district -scale exploration

project to our property portfolio. We are acquiring these Tombstone properties because we see an

entire district with a prolif ic history of small scale, high -grade mining and a significant lack of modern

exploration to discover new orebodies. We have identified several shallow oxide and deeper sulphide

precious and base metal exploration targets in the Property, including in and around the Contention Pit.

“We believe t he Baroyeca P roperties have substantial untapped potentia l, especially below the water

table around 600 feet deep, because that is where the oxide ores stopped and sulfide ores could start.

CRD deposits are typically related to granitic intrusions where the source of gold -silver mineralization

could be a porphyry type system. We will take a systematic approach to exploring the properties by

digitizing all histor ic work, evaluating available data on small historic gold -silver deposits, and

completing detailed surface work such as structural and alteration mapping, geochemical sampling and

geophysical surveying followed by drilling.”

Joey Wilkins, B.Sc., P.Geo., is the Qualified Perso n who reviewed the historic data, visited the property

and approved the technical disclosures in this news release.
