Themac Resources Group Limited Announces New Mexico State Engineer's Decision on Santa Teresa Water Transfer

MWN-AI** Summary

THEMAC Resources Group Limited (TSXV: MAC) announced on September 5, 2025, that the New Mexico State Engineer has denied its application for transferring water rights associated with the Copper Flat Project. This decision follows an administrative hearing held in August 2023, after the company had originally filed the application in August 2019. The application sought to divert 2,400 acre-feet of existing Santa Teresa water rights for use at the Copper Flat Mine, managed through THEMAC's subsidiary, New Mexico Copper Corporation.

In light of the denial, THEMAC is reviewing the decision and contemplating its next steps. The company has also been exploring alternative water management strategies to mitigate reliance on the Santa Teresa water rights. Among these alternatives is the implementation of dry stack tailings technology, which promises a more sustainable and safer waste management approach. THEMAC is currently in the advanced stages of assessing the feasibility of this technology, awaiting more detailed analyses for both its implementation and related permitting processes.

Investors and stakeholders are advised to stay informed as the situation develops, given the potential impact of this decision on the Copper Flat Project and the company's broader operational strategies. The press release includes cautionary statements about forward-looking information, underscoring the inherent risks and uncertainties that could influence outcomes. Stakeholders should consider these uncertainties while making informed decisions regarding THEMAC’s future actions and overall viability. For more details, the company encourages visiting their official website or reviewing filings on SEDAR+.

MWN-AI** Analysis

The recent announcement by THEMAC Resources Group Limited regarding the New Mexico State Engineer's denial of the water transfer application has significant implications for investors considering the Copper Flat Project. With the denial, the anticipated operational rollout could experience delays, thereby affecting production timelines and potential cash flows.

Investors should focus on two key areas: the implications of the water rights denial and the ongoing exploration of alternative water management strategies. The denial not only poses immediate operational challenges but may also increase regulatory scrutiny and add further uncertainties to the project.

However, the Company's proactive approach to researching alternative environmentally sustainable water solutions, such as dry stack tailings technology, highlights a positive pivot. This strategy offers potential long-term benefits, including enhanced risk management regarding water scarcity and improved project sustainability. If successfully implemented, these innovations could strengthen the Company's position in a resource-driven economy, thereby enhancing investor appeal.

In the short term, market sentiment may lean towards cautiousness, given the negative regulatory outcome. Investors should closely monitor the Company’s subsequent actions and the feasibility studies on dry stack technology, as shifts here can alter perceptions of the project's viability. Additionally, fluctuations in copper prices and evolving regulatory landscapes in mining should inform investment decisions.

As always, potential investors are encouraged to conduct thorough due diligence and consider long-term growth prospects against immediate setbacks. Revisiting the fundamentals of THEMAC, including production capacity, commodity price projections, and strategic pivots in technology adoption, will provide a clearer picture of the stock's future performance. Therefore, adopting a wait-and-see approach might be prudent until further clarity emerges from the ongoing reviews and technical evaluations.

Vancouver, British Columbia--(Newsfile Corp. - September 5, 2025) - THEMAC Resources Group Limited (TSXV: MAC) ("THEMAC" or the "Company") provides the following update in relation to its Copper Flat Project and application for the transfer of water rights:

In April 2019, an agreement to lease 2,400 acre-feet (AF) of existing Santa Teresa water rights for use at the Copper Flat Mine by the Company's wholly owned New Mexico Copper Corporation was entered into. An application to change the point of diversion to the Copper Flat production wells and the place and purpose of use to the Copper Flat Mine was filed in August 2019 with the New Mexico State Engineer's Office (NMSEO), and an administrative hearing was held in August 2023.

The New Mexico State Engineer has now handed down her decision denying the Application. The Company is currently reviewing the decision and considering its next steps in the process.

Since the Application was originally filed with the NMSEO, the Company has been investigating alternative options for more economically favourable and sustainable water management systems for implementation at the Copper Flat Project that would alleviate the need to access any of the Santa Teresa water rights. Those options include dry stack tailings technology allowing for safer and more sustainable waste management at the Copper Flat site. The feasibility of the dry stack technology is now at an advanced stage of evaluation by the Company, and is subject to ongoing further detailed analysis in respect to both the implementation of the technology and permitting.
