Tombstone Project Overview

Aztec Minerals holds a 85.0% interest in the Tombstone Property Joint Venture, which includes most of the original patented mining claims in the main district as well as some recently acquired properties

The main target of the current drilling is to continue testing the shallow, bulk tonnage, potentially heap leachable, mesothermal gold-silver oxide mineralization adjacent and below the previously mined Contention pit by step-out drilling. Future drilling is expected to focus on follow-up on the current program's results. It is anticipated that possible targeting could include strike and dip extensions of the shallow oxide mineralization, and move along those trends deeper into the sulfide zone as historically there was significant production to 300 m depth^*2.

The Tombstone project is located 100 kilometers (km) southeast of Tucson, Arizona and covers much of the historic Tombstone silver district. Tombstone is renowned for its high grade, oxidized, silver-gold mesothermal stringer lode veins, hydrothermal breccias and manto CRD orebodies that were mined in the late 1800's and early 1900's. The historic silver production in the Tombstone district from 1878 to 1939 was estimated at 32 million ounces and 250,000 ounces of gold^*2.

The district geology consists of a mix of shallow-level, oxidized Au-Ag and base metal deposits related to CRD and skarns hosted in folded and thrusted sediments, intrusive dikes, and lode veins, and as well the under explored, sulfide versions located below the water table.

Host rocks to the mineralization are primarily the clastic sediments of the lowest portion of the Cretaceous Bisbee Formation. Between 50 and 300 meters (m) in depth, the Bisbee is underlain by approximately two kms thick of the same Paleozoic carbonate formations that host the Hermosa-Taylor zinc-lead-silver deposit of South32 located 60 km southwest of Tombstone.

Aztec believes that the historic silver mines at Tombstone could be related to a much larger mesothermal system with CRD mineralization below the old mines. Since 2017, Aztec has completed geological mapping, geochemical sampling and geophysical surveying to identify the most prospective areas for Au-Ag mineralization around and below the Contention open pit, and CRD zinc-lead-copper-silver-gold mineralization below the entire district. Aztec management views the district as highly prospective for the discovery of mesothermal and CRD mineralization.

Summary Tombstone Project Highlights

• Well located property on patented (46) and unpatented (73) claims (833 hectares / 2058 acres), covers much of the historic Tombstone silver mining district, great infrastructure, local town, road access, full services, water, power

• Historic silver district^*2 produced 32 million ounces of silver and 250,000 ounces of gold from 1878-1939, in high grade, oxidized, silver-gold-lead-zinc-copper vein, breccia and CRD deposits, and small open pit heap leach production in late 1980's

• Drilling by Aztec in 2020-25 has demonstrated that the Contention Pit target has significant, shallow, oxidized Au-Ag bulk tonnage mineralization which is open in all directions

• Multiple other prospective targets in Cretaceous and Paleozoic rocks related to major NW and NNE trending structures hosting porphyritic intrusions crosscutting a possible caldera ring structure

^* Aztec has not verified these historic results and is not relying on them. Aztec has in its possession the historic drill logs, maps and reports but does not have any information on the quality assurance or quality control measures taken in connection with these historical exploration results.
