Kingman Begins Phase III Drilling to Test Southwick Vein Step-Out at Mohave

Rhea-AI Summary

Kingman Minerals (OTCQB: KGSSF) has started Phase III diamond drilling at the Mohave Project, mobilizing a drill rig to collar P3-05/P3-06 on February 27, 2026. The program comprises four locations and 814.7 metres of HQ drilling planned to test the Southwick vein step-out beyond the historic Rosebud mine area.

The program follows the company's structural interpretation and magnetic vector inversion model and uses paired holes to target the projected vein extension at depth.

Positive

• 814.7 metres of planned HQ diamond drilling
• Phase III targets Southwick vein step-out beyond historic mine area
• Four drill locations including paired southeast holes to test depth continuity

Negative

• Program just mobilized; there are no assay results reported yet
• Planned drilling is exploratory and outcome is uncertain

Vancouver, British Columbia--(Newsfile Corp. - February 27, 2026) - Kingman Minerals Ltd. (TSXV: KGS) (OTCQB: KGSSF) (FSE: 47A) ("Kingman" or the "Company") is pleased to announce that the Altar Drilling crew has mobilized to site and assembled the drill rig at the first planned collar location (P3-05 / P3-06) for Phase III diamond drilling at the Mohave Project in Arizona.

Brad Peek, QP and Director of the Company states: "Phase III comprises four drill locations - three locations southeast of the Rosebud Mine and one to the northwest. All holes are designed to intersect the projected step-out extension of the Southwick vein system beyond the historic mine area. At the southeastern pads, paired holes at -45° and -60° are oriented to intersect the projected vein extension at depth."

The HQ diamond drill holes are totaling 814.7 metres (2,673 feet) of planned drilling. The Phase III drill collar locations are summarized in Table 1.
