Rio Grande Resources Completes LiDAR and MAG Survey s on its
Winston Group of Gold/Silver Properties in New Mexico, USA
VANCOUVER, British Columbia, 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.

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.
