Kingman Completes Drilling at High-Grade Mohave Project and Historic Rosebud Mine; Intersecting Thickest Intervals to Date

Rhea-AI Summary

Kingman Minerals (OTCQB: KGSSF; TSXV: KGS) completed eight Phase III core holes at the Mohave project targeting the historic Rosebud Mine area on April 21, 2026. Phase III focused southeast of a newly mapped NE-SW fault (“Rosebud South”) and intersected thicker projections of the Southwick veins, with visual intercepts up to 26 feet (7.9 m) (not true width). Core samples were sent to Skyline Laboratories in Tucson for assay and results are pending. Standard NI 43-101 protocols and Qualified Person review were applied.

Vancouver, British Columbia--(Newsfile Corp. - April 21, 2026) - Kingman Minerals Ltd. (TSXV: KGS) (OTCQB: KGSSF) (FSE: 47A) ("Kingman" or the "Company") is pleased to announce that the Company has completed its 8-hole Phase III core drilling using Altar Drilling of Tucson, Arizona. Phase III drilling targeted a previously untested area near the historic Rosebud Mine, which produced high-grade gold approximately 100 years ago. The target area lies southeast of a fault identified through the Company's recent drone magnetic survey. The survey was flown by Storm Exploration LLC and interpreted by Fathom Geophysics LLC.

The survey revealed the location of several faults on the property and the magnetic properties of each fault block. The Phase III drilling focused on the southeast side of a major NE-SW trending fault, herein named the "Rosebud South" fault. The fault was previously undetected because recent gravel deposits hid it. Veins on the northwest side of the fault, the two parallel Southwick veins, were mined 100 years ago and have been confirmed by the Company's underground sampling program and two phases of drilling. These veins are high-grade (up to several hundred g/T Au) but narrow structures. The veins were traced across the Rosebud South fault by the magnetic survey.

Image (Left): Observed iron-oxide staining in surface runoff reflects oxidation of iron-bearing minerals exposed during drilling, consistent with hydrothermal alteration processes commonly associated with gold systems. While not indicative of mineralization on its own, the feature supports ongoing geochemical activity and warrants further analysis.

Image (Right): Observed drill core displays intervals of alteration and variable mineralization textures, including zones of oxidation and veining consistent with hydrothermal processes.

The initial four holes of the Phase III program have intersected projections of the two Southwick veins and several other structures. The veins are much thicker than anything seen in the Rosebud Mine workings or in the first two drilling phases but appear to consist of the same type of mineralization as in the mine workings. Intercepts of visually encouraging alteration/mineralization up to 26 feet (7.9 meters) (not true width) have been recorded and are being sampled.

The first samples have been delivered to Skyline Laboratories in Tucson, Arizona, for analysis. Assays are pending. Standard NI 43-101 protocols are being used for the handling and sampling of the core.

Brad Peek, Consulting Geologist and a Kingman Minerals Director, stated, "We are very excited by the widths of the structures, the intensity of the mineralization, and the number of structures intersected by these first drill holes."

ABOUT

Kingman Minerals Ltd. (TSXV: KGS) is a publicly traded exploration and development company focused on precious metals in North America. The Company's flagship Mohave Project includes the historic Rosebud Mine, located in the Music Mountains, Mohave County, Arizona. High-grade gold and silver veins were discovered in the area in the 1880s and were mined mainly in the late 1920s and 1930s. Underground development on the Rosebud property included a 400-foot main shaft and approximately 2,500 feet of drifts, raises and crosscuts.

FAQ

What did Kingman Minerals (KGSSF) announce about Phase III drilling at Mohave on April 21, 2026?

Kingman completed eight Phase III core holes targeting the Rosebud Mine area and Rosebud South fault, intersecting thicker vein projections. According to Kingman, visual intercepts reached up to 26 ft (7.9 m), and core samples were sent to Skyline Laboratories for assay.

How significant are the reported 26 ft (7.9 m) intercepts in KGSSF's April 2026 drilling update?

The 26 ft intercepts are visually encouraging but are not reported as true width and remain unassayed. According to Kingman, these intervals show alteration and veining consistent with hydrothermal gold systems and are being analyzed under NI 43-101 protocols.

What role did the drone magnetic survey play in KGSSF's Mohave drilling program?

The drone magnetic survey identified several fault blocks and traced the Southwick veins across the Rosebud South fault, guiding Phase III targets. According to Kingman, the survey was flown by Storm Exploration and interpreted by Fathom Geophysics.

Where were KGSSF's drill samples sent and when will assay results be available?

Core samples from Phase III were delivered to Skyline Laboratories in Tucson for analysis and assays are pending. According to Kingman, standard NI 43-101 handling and sampling protocols are being followed while results remain outstanding.

Who reviewed and approved the technical information in Kingman's April 21, 2026 drilling release (KGSSF)?

The technical information was reviewed and approved by Brad Peek, M.Sc., CPG, a Qualified Person and director of Kingman Minerals. According to Kingman, Mr. Peek certified the release under NI 43-101 standards.
