VANCOUVER, BC / ACCESS Newswire / February 27, 2025 / Rio Grande Resources Ltd. (CSE:RGR) ("Rio Grande" or "RIO" the "Company"), an emerging North American gold and silver exploration company is pleased to announce the successful completion of a high-resolution LiDAR and magnetic survey over its Winston Group of Gold and Silver Properties ("Winston" or the "Winston Project") located in the Black Range Mountains in the Chloride Mining District of Sierra County, New Mexico, USA. The magnetic survey, conducted by KLM Geoscience, ("KLM") Las Vegas, Nevada, a leading geophysical services provider, was carried out to advanced specifications and marks a significant milestone in the company's exploration program.
Magnetic Survey
Magnetic surveys provide detailed geophysical data to assist in identifying subsurface structures and magnetic anomalies associated with mineralization. KLM utilized advanced equipment including a Gem Systems GSM-19W rover magnetometer with integrated GPS. This cutting-edge technology ensures high-quality data collection, enabling precise interpretation of magnetic anomalies. The scope of the magnetic survey at the Winston Project included the following parameters:
Grid Azimuth: 90°
Line Spacing: 50m, 100m, 200m
Coordinate System/Datum: UTM Zone 13T / WGS84
Line Length: 1km - 2.6km
Number of Lines: 31
Total Line Kilometers per Grid: 66km
"We are extremely excited about the completion of these surveys," said Jason Barnard, CEO of Rio Grande Resources. "The combination of LiDAR and magnetic data provides us unique insights into the property's geology and mineralization potential. The company remains committed to advancing its exploration efforts in a systematic and data-driven manner, with the goal of delivering value to shareholders"
Magnetic surveys measure the local variations in the Earth's magnetic field caused by magnetic minerals in the rocks. Variable magnetic susceptibility in the local host rocks (rhyolite-andesite-limestone) provides good contrast and the identification of rock units and structural zones. The maps highlight the boundaries of magnetic bodies, making it easier to identify geological structures like faults or contacts between rock types. The gold and silver veins of the Winston Project have emplaced along these structural zones, which can be delineated from a magnetic signature (see figure 1 below).

Interpreting the Data: RTP (reduce to pole) Maps and Magnetic Survey Colors
Magnetic Survey maps correct for the inclination of the Earth's magnetic field, making magnetic anomalies align directly over their sources. The colors reference indicate:
Warm Colors (red, orange): strong magnetic responses, often associated with magnetic minerals present in Andesite or intrusive rocks
Medium Colors (yellow-green: intermediate response that generally correlates with rhyolite, that locally cover andesites of variable thickness
Cool Colors (blues): represent weak magnetic responses, which indicate non-magnetic rocks such as limestone; or alteration zones that may be associated with gold and silver mineralization
LiDAR Survey
LiDAR (Light Detection and Ranging) data was acquired over 42 square miles, providing detailed topographic control of the area. By emitting laser pulses, LiDAR can create a highly accurate representation of the terrain and surface elevation. The LiDAR-derived elevation data collected from Winston, enabled the remote identification of historic mining activities (e.g., prospect pits) and structural features, while also facilitating precise measurements for targeting and drill planning in a 3D space. The Company was able to produce very detailed digital elevation models and better maps to use in structural geology studies for identification of stockpile ore and dumps, and historical mineral exploration sites (see figure 2 below).

This data is invaluable for identifying geological features, such as faults, fractures, and outcrops. It will assist in assessing features of the property with considerable precision and flexibility, and in turn, be able to determine which veins and holes to target with higher degree of accuracy, which may influence gold deposition. The data will be integrated with magnetic data to generate a comprehensive geological model of the project.
Next Steps
Rio Grande Resources is analyzing and integrating all data to identify high-priority targets for follow-up exploration, including soil sampling, geochemical and geophysical analysis, and future drilling. The integration of LiDAR and magnetic data will guide exploration activities.
Equity Grants
Rio Grande would also like to announce that it entered into an investor relations consulting agreement with MZHCI, LLC ("MZHCI") to provide investor relations and corporate communications services for an initial twelve-month term commencing on February 26, 2025, which shall automatically renew for successive twelve-month terms until terminated by either party on providing sixty days' notice, in consideration of USD$3,500 per month and 1,278,453 stock options of the Company, exercisable at $0.065 per share and valid for a 5 year term. MZHCI does not currently own any interest, directly or indirectly, in the Company or its securities aside from the option grant. MZHCI's address is Aliso Creek Road, Suite 250, Aliso Viejo, CA, 92656 (phone: (262) 357-2918, email: RGR@mzgroup.us). MZHCI and its directors and officers are arm's length from the Company.
Further, the Company announces that it has granted an aggregate 20,000 stock options to an officer and consultants of the Company, exercisable at $0.065 and valid for a 2 year term.
All stock options issued are subject to a statutory hold period of four months and one day and have been granted in accordance with the Company's Omnibus Long-Term Incentive Plan dated December 20, 2024 and the policies of the Canadian Securities Exchange.
