(TSXV:AZT)(OTCQB:AZZTF) ("Aztec" or the "Company") announces it has engaged Kappes, Cassiday & Associates ("KCA") to conduct initial bottle-roll NaCN leach testing on samples from the Tombstone Project as a continuation of shake tests completed earlier this year. The bottle-roll tests will be conducted on drill samples from multiple lithologic types and grade levels of oxidized gold-silver mineralization found at the Tombstone Project. This testing is expected to advance the metallurgical characterization of the various mineralization types of the Project.Simon Dyakowski, President & CEO of Aztec Minerals, commented: "Metallurgical testing of our extensive intercepts of oxide gold-silver mineralization represents a key stepping-stone to de-risking the brownfield gold-silver Tombstone Project. This work, in combination with the upcoming maiden Mineral Resource Estimate (MRE), is expected to demonstrate the Tombstone Project's potential to become of greater economic significance to the local economy and the State of Arizona."Tombstone Drilling Program UpdateThe current Tombstone Project drilling campaign has completed a combined 17,927 metres of reverse circulation ("RC") and core drilling across 87 drill holes that commenced last year, and is continuing to drill test the Northern Exploration area. Since January 1, 2026, Aztec has drilled 42 RC drill holes and 5 core holes, and has reported the results from the initial 19 RC holes drilled. A further 23 RC holes and 3 core holes have been shipped to analytical labs in Hermosillo, Mexico and Tucson, Arizona, and are awaiting final geochemical analytical results which the company expects to release in batches over the next 60 days.Aztec Launches New WebsiteAztec also announces the launch of its new website now live at https://aztecminerals.com/.
