Kingman Reports 82.3% Gravity-Recoverable Gold and 93.5% Preliminary Gold Recovery from Rosebud Metallurgical Testing
Kingman’s high recovery metallurgy validates Rosebud processing potential while the company’s cash runway remains tight.
Kingman Minerals Ltd. announced preliminary metallurgical test results from Sepro Laboratories on its Rosebud Gold Property in Arizona. Tests achieved a preliminary 93.5% overall gold recovery using a combined gravity and rougher flotation flowsheet. Gravity Recoverable Gold (GRG) was identified at 82.3% at a P80 grind size of 75 microns.
The Master Composite sample graded 12.52 g/t Au, with significant grade variability attributed to the "nugget effect." Flotation kinetics showed rapid recovery, with 36.9% of gold entering a concentrate in the first four minutes. Silver recovery was approximately 63.1% from a composite grading 60.5 g/t Ag.
Next steps include cleaner flotation optimization, mineralogical investigation, and potential leaching of flotation tailings to further improve recovery.
Kingman Minerals Ltd. (KGS) released metallurgical results that align with prior expectations established by historic underground sampling, which returned grades up to 688 g/t Au, and previous Phase III drilling that identified high-grade, albeit discontinuous, mineralization. The findings serve as a logical follow-up to the March 2026 underground sampling program and the April/May 2026 drilling updates, validating the processing route without altering the company's exploration-stage status.
No new resource estimate, economic study, or financing was announced alongside the results. The impact on the stock is incremental and expected by the market. Prior-period financial context for Q1 2026 shows a net loss of $748,493 and cash of $796,580. The company remains fully exploration-stage with no revenue, and the metallurgical data does not immediately change the capital intensity or dilution risk profile.
Kingman Minerals Ltd. is a pre-revenue exploration company focused on the Mohave Project in Mohave County, Arizona. The flagship asset includes the historic Rosebud Mine and surrounding lode claims, totaling 192 claims (1,216 hectares). The project sits in a historic gold-silver district with over 140 years of mining activity.
The project is currently in the Exploration/Brownfield stage. No NI 43-101 compliant resource has been defined to date. Historical data suggests potential for up to 664,000 oz Au and 2.6M oz Ag, but these are non-verified estimates. Recent work has focused on underground sampling, drone magnetic surveys, 3D structural modeling, and Phase III drilling to test deeper extensions.
