Zephyr Provides Dawson Gold Update
Zephyr awaits Colorado permit resubmission for its Colorado project amid tight cash runway and dilution risks.

Executive Summary
- Zephyr Minerals provided an operational update on its Dawson Gold project in Colorado, confirming the successful completion of the third quarter of its groundwater monitoring and analytical program.
- The fourth quarter of monitoring is scheduled for September 2026, with the full five-quarter program targeted for completion by year-end 2026.
- The company plans to resubmit its mining permit application to the Colorado Division of Reclamation, Mining and Safety (DRMS) in January 2027, contingent upon receiving and reviewing all analytical data.
- The release reiterates the historical July 2013 inferred resource estimate of 343,000 tonnes grading 12.11 g/t Au for 133,500 oz at a 5 g/t cut-off.
- A 2017 Preliminary Economic Assessment (PEA) indicated an all-in sustaining cost (AISC) of $692/oz using a $1,250/oz gold price.
- Management highlighted exploration upside at depth, along the 700-metre Sentinel zone, and in the Windy Gulch and Windy Point areas.
- The company is awaiting Zimbabwean Government approval for two Exclusive Prospecting Orders (EPOs) covering 124,000 hectares applied for in 2021.
Material Impact
- The update is a standard operational milestone confirming that the groundwater monitoring program remains on schedule.
- No new drilling results, resource updates, or changes to the permitting timeline were disclosed.
- The financial and operational implications remain unchanged from prior announcements. The company continues to rely on the 2013 resource estimate and 2017 PEA, which are dated and do not reflect current gold prices or modern exploration data.
- The news is expected and incremental, providing no material catalyst for immediate price appreciation or downside protection.

Company Overview
- Zephyr Minerals Ltd. is a junior mining company focused on advancing its 100% owned Dawson Gold property in Fremont County, Colorado, while pursuing exploration licenses in Zimbabwe.
- The flagship Dawson Gold deposit holds a historical inferred resource of 343,000 tonnes grading 12.11 g/t Au for 133,500 oz at a 5 g/t cut-off.
- A 2017 PEA modeled an underground mine with an AISC of $692/oz at a $1,250/oz gold price. Current gold prices significantly improve the project's theoretical economics, but the resource has not been updated since 2013.
- The company is conducting a five-quarter groundwater monitoring program to satisfy Colorado regulatory requirements for a mining permit resubmission.
- Additional exploration targets include the Sentinel zone, Windy Gulch, and Windy Point, alongside placer gold evaluation on the Judith Patented Placer Claim.
- The company is also awaiting approval for two EPOs in Zimbabwe covering 124,000 hectares for gold and lithium exploration.
