Kingman Finalizes 3D Magnetic Model and Engages Altar Drilling for Phase III at Mohave

Vancouver, British Columbia--(Newsfile Corp. - February 13, 2026) - Kingman Minerals Ltd. (TSXV: KGS) (OTCQB: KGSSF) (FSE: 47A1) ("Kingman" or the "Company") is pleased to announce that it has completed a project-scale, three-dimensional magnetic vector inversion ("3D MVI") model and has engaged Altar Drilling Inc. ("Altar") to carry out the proposed Phase III diamond drill program for its high-grade gold-silver Mohave Project ("Project") in Arizona.

3D Magnetic Vector Inversion ("MVI")

Magnetic data were collected over the Project area in December 2025 using a high-resolution drone-based airborne magnetic ("MAG") survey (see Kingman news release dated November 20, 2025, for additional details).

Subsequently, the Company retained Ohio-based Fathom Geophysics LLC to process the magnetic data and complete the 3D MVI interpretation. Work included staged filtering and inversion steps, including standard magnetic data filtering, two-dimensional structural detection, magnetic vector inversion, three-dimensional structural detection, and integrated structural and lithological interpretations.

Based on this workflow, the 3D MVI model outlines the geometry and orientation of interpreted magnetic lineaments and boundaries across the Mohave Project area, including a population of northwest-trending lineaments broadly parallel to mapped vein orientations. Three-dimensional edge detection of the magnetization-vector amplitude (Figure 1) was used to sharpen these boundaries and help constrain the continuity of the northwest-trending lineaments.

"The 3D magnetic vector inversion highlights a coherent set of northwest-trending magnetic features that align closely with mapped vein structures and the footprint of historic workings at the Rosebud Mine" said Daniel Core, PhD, Principal Geophysicist and Geologist of Fathom Geophysics LLC. "These features define clear structural vectors that can be tested for continuity along strike and at depth within the Phase III target corridor and provide a robust framework for broader exploration targeting at the property scale."
