Rock Edge Confirms Spodumene Pegmatite at Superb Lake Project

Vancouver, British Columbia, July 18, 2023: Rock Edge Resources Ltd. (the “Company” or “Rock

Edge”) (CSE:REDG) is pleased to announce that Dahrouge Geological Consulting Ltd. (“Dahrouge

Geological”) has completed the follow-up field program for Lithium-Cesium-Tantalum (LCT) type

pegmatite(s), announced June 21, 2023, on our Superb Lake Property (the “Project”), situated in

northwestern Ontario.

The program has yielded exciting results, including the sampling of spodumene bearing pegmatite

and the discovery of a significant extension to the known spodumene-bearing trend extension.

During the field program, a total of 24 samples were collected from across the Superb Lake

Property. Among these, four-4 pegmatite samples were confirmed as spodumene bearing.

Spodumene is a key lithium rich mineral, highlighting the Property’s potential for LCT -type

pegmatites. Additionally, the known trend of spodumene-pegmatites has been extended to an at

least 200 metres (Figure 1).

CEO Charles Desjardins expressed his enthusiasm about the results, stating, "The completion of

our work program at the Superb Lake Property has provided us with encouraging findings. The

discovery of spodumene -bearing pegmatite samples, along with the extension of the known

mineralized trend and the appearance of additional showings, significantly enhance the Property's

potential. We look forward to further exploration efforts in this highly promising area."

All samples have been submitted to an independent, ISO accredited analytical laboratory for

analysis. Rock Edge will now focus on a comprehensive review of results from the field program

and determine the next steps for exploration of the Superb Lake Property.

The Superb Lake P roperty encompasses approximately 2,378 hectares in the O’ Sullivan Lake /

Maun Lake Area of the Thunder Bay Mining District of Northwestern Ontario, Canada.

Geologically, the property is situated in the eastern part of Wabigoon Subprovince of the Superior

Geological Province. The Superb Lake area has historical exploration carried out since the 1950s

with the discovery of lithium along the shores of Superb Lake. The discovery outcrop was reported

to have a minimum outcrop exposed length of 16 m, while its exposed width varies from 2.5 m to

a maximum of 3.7 m. In 2020, f our samples collected from a spodumene rich part of the dyke

returned 1.77 % to 4.03% Li2O.

Channel Samples assays

During Medaro Mining Corp.'s (“Medaro”) previous exploration o f the Superb Lake Lithium

Property, Medaro collected channel samples to assess the potential of the area. These samples

(see press release dated December 14, 2022), which yielded significant results, were collected by

Medaro prior to the completion of option agreement with Rock Edge.

The highest grades obtained from the sample program included 5.84 % Li2O over 1.1m, which was

from a 3.2 m wide exposed portion of the dyke. Highlights follow:

• The main Superb Lake Pegmatite is 3 to 3.8m wide in surface outcrop and can be traced

for about 100 m along strike. It appears to continue undercover at both ends.

• The pegmatite varies from fine grained to very coarse grained spodumene, with local

zones of aplite. Surface assays suggest overall better grades within its western portion.

• A total of 13 channel samples, with lengths from 0.3 m to 1.5 m, were cut in four channels:

o Channel #1 - 0.43% Li2O across 3.2 meters;

o Channel #2 - 0.65% Li2O across 3.8 meters;

o Channel #3 - 2.47% Li2O over 3.2 meters; and

o Channel #4 - 1.29% Li2O over 2.9 meters.

Superb Lake Lithium Property Review:

Airborne Survey Highlights - Airborne geophysical survey news release March 02, 2023

• Superimposition of the 2021-22 soil sampling contours (Li ppm) on the magnetic tilt map

highlights four areas of interest ( “AOI”) with good potential for spodumene

mineralization. Areas of P1, P2, P3, and P4 are categorized as exploration targets with

LOW magnetic responses and LOW VTEM conductivity (see Figure 2),

• The northwesterly trend of lithium assay contours implies that LOW magnetic, LOW

conductive zones adjacent to mafic dykes or veins may be associated with spodumene -

bearing lithium mineralization, and

• The superimposition of the dB/dt Calculated Time Constant (Tau) and the Fraser filtered

VTEM responses on Magnetic Tilt Derivative contours also reflects four AOI (T1 to T4 ,

Figure 2) with the highest potential for sulphide and graphite mineralization as we ll as

base polymetallic deposits within the property. The result clearly indicates zones of

potentially high concentration of sulphide mineralization with anomalous magnetic /

conductive features that are spatially coincident with existing major faults/fractures, and

the boundaries of the metavolcanics with pegmatitic granite and metasedimentary rocks.

In 2022, Medaro contracted Geotech Ltd. of Ontario, Canada , to complete a Versatile Time

Domain Electromagnetic (VTEM TM Plus) and horizontal magnetic gradiometric survey on the

Superb Lake Property. A total of 883-line kilometers at 50 m line spacing was completed on the

property.
