Casa Grande, AZ and Toronto, ON, February 28, 2022 – Arizona Sonoran Copper Company Inc. (TSX:ASCU) (“ASCU” or the “Company”), an emerging US-based copper developer and near-term producer is pleased to announce a positive review of the jurisdictional waters on the Company’s newly rezoned LKY, ARCUS and Merrill by the United States Army Corps of Engineers (“USACE”). As a result, all future permitting processes at Cactus will continue to be driven by State and County levels.

USACE evaluated ASCU’s plans for the reopening of the Cactus Mine, located 4km west of Casa Grande. The government agency determined that the mine is not located within the jurisdictional Waters of the United States (“WOTUS”) and therefore does not require a federal permit under Section 404 of the Clean Water Act.

ASCU VP Sustainability and External Relations, Travis Snider commented “This is a tremendous step forward for the Project. With this final determination by the Army Corps, State and County are the only remaining permits needed to re-open the Cactus Mine. As we advance towards our prefeasibility study, gain a better understanding of the site characteristics, and move closer to making a construction decision, having this certainty is key.”

The approved jurisdictional determination (“JD”) was issued by the USACE under the statutes regulating WOTUS within the Clean Water Act (“CWA”). In the United States, the CWA is the primary federal law regulating water and the language of the act defines WOTUS as navigable waterways. USACE is the lead agency in evaluating which waterways are navigable.

Neither the TSX nor the regulating authority has approved or disproved the information contained in this press release.
