Red Rock Canyon Gold Project IP Report | Sub Rosa Monitoring LLC, July 2025
Sub Rosa Monitoring LLC performed a resistivity and induced polarization (IP) survey over a small grid within the Redrock Canyon site located approximately 5 miles southeast of Tombstone, Arizona, July 24 – 30, 2025. The survey was conducted over an area previously tested with drilling. “The primary purpose of the survey was to determine the correlation, if any, between the areas of known gold mineralization and the electrical geophysics.” A good correlation between both resistivity and IP with the jasperoidal veining, associated sulfides and gold assays in the drillholes was confirmed. The veins produced diagnostic signatures that were readily traceable to specific locations. The combination of mineralized veins and diffuse mineralization within the adjacent limestones provided easily identifiable drilling targets. The results of the survey provide confirmation that the known gold mineralization, previously determined from geochemistry and drilling, was readily manifested in the geophysical data. Structural features, either mineralized or not, and their orientations were detected and mapped by the electrical geophysics.” (Liberty Star Minerals Redrock Canyon IP and Resistivity Field Survey, p.3)

The Red Rock Canyon target consists of 6,653 acres of Arizona MEPs and 320 acres of unpatented Federal Lode Mining Claims. The area has been segregated from the larger Hay Mountain Project block after the examination of jasperoids bodies that displayed gold values. In the Technical Report:
- Compilation of previous drilling results, by others as noted in The Technical Report, indicates that 12 of 17 intercepts reported gold at grades above what is considered current cut off grades, 0.022 oz per ton (0.68 gpt).
- These historical intercepts range from five (5) to forty-five (45) feet in vertical extent and reveal multiple mineralized zones. Grades in the larger intercepts are reported up to 0.182 ounces per ton (5.66 gpt).
- In addition to three field visits (2020, 2021) tech team investigated previous findings including geochemical studies, geophysical surveys, field notes and drill logs.
- Given surface study results combined with previous drilling information, Mr. Guarnera concludes that new drilling aimed at expanding the areal extent of economic gold concentrations certainly has merit.
Dr. Alan Wilson’s Hay Mountain Project Presentation Jan 2020
Liberty Star’s 2011 technical report over the larger area.The Hay Mountain Exploration Report was compiled by SRK Consulting under Qualified Persons Corolla K. Hoag & Jan C. Rasmussen. This 195-page Canadian NI 43-101 compliant document relied on extensive field visits and detailed research of previous exploration studies of the area.
Outside Expert Source UVF Study November 2020 In late November 2020 Liberty Star received a second UVF study from an outside expert source (under confidentiality agreement) using a more powerful shortwave UVF light that utilizes a wavelength of 254 nanometers Vs 365 nanometers that was used in July on the Field Mapping 2020 collected samples completed by contract Geologist Daniel Koning. The outside higher-powered equipment verifies what Liberty Star presented in the initial offering, Hay Mountain Project July 2020 Field Mapping Report. The presentation includes the outside expert source’s map and data table, formatted according to Koning’s July 2020 data table.

Hay Mountain Project July 2020 Field Mapping Report – Prepared by Daniel Koning Contract Geologist From July 14th to August 5th, 2020 Geologist Daniel Koning conducted field mapping over the Hay Mountain Project. “The purpose of the mapping was to identify alteration and veining associated with an inferred porphyry copper system at depth, determine the extent of hydrothermal alteration, and comment on the possible timing of mineralization.” Dr. Alan Wilson (Hay Mountain: a large, undrilled Cu-Mo-Au Porphyry – Skarn target in the Laramide Copper Province, AZ, USA) notes,”of particular importance is the observation of increased vein intensity in outcrops surrounding the already identified targets, which suggests proximity to a large, potentially copper-bearing hydrothermal system.” Mapping was conducted at 1:10,000 scale and a total of 183 carbonate vein samples were taken for pXRP analysis and UV fluorescence response.” This report contains over 50 new field images and maps.”
