ROCK EDGE ASSAYS RETURN 2.47% LITHIUM OXIDE OVER

3.2 METERS AT SUPERB LAKE LITHIUM PROPERTY,

ONTARIO

Vancouver, British Columbia, December 14 th, 2022 : Rock Edge Resources Ltd. (the "Company"

or "Rock Edge") (CSE: REDG) is pleased to announce results as received from Medaro Mining Corp. (CSE:

MEDA) for channel samples from the Phase 2 exploration program on its Superb Lake Lithium Property

(the “Property”), located in Northwestern Ontario, Canada. The Company recently optioned the Property

and has the right to acquire an undivided 70% interest (see PR dated November 29, 2022).

The highest-grade zone from the sample program was 5.84 % Li2O over 1.1m, which was across a 3.2 m

wide 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 under glacial cover 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 15 channel samples from 0.3 m to 1.5 m were cut in four channels (see Table 1 below)

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

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

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

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

Each channel sample from this work varies from a 0.3 to 1.5 meter long, 5 cm wide and 3-5 cm deep cut of

the bedrock. Samples were bagged and tagged using best practices and were delivered to Activation

Laboratories (“ACTLABS”), Ancaster, Ontario for sample preparation and analyses using their code

Ultratrace 7. ACTLABS is an independent commercial, accredited ISO Certified Laboratory.

Airborne Geophysical Survey Update

The Company is also pleased to announce the completion of a Versatile Time Domain Electromagnetic

(VTEMTM Plus) and horizontal magnetic gradiometric survey on the Superb Lake Property. 883 -line

kilometres of survey at 50 m line spacing was contracted in August 2022 to Geotech Ltd. of Ontario, Canada.

The survey has been flown and Geotech Ltd. is currently in the process of compiling the airborne survey

data and reporting. The survey type is an exclusive technology of Geotech Ltd. and is suitable to identify

deeper geophysical targets and structures.

Charles Desjardins, CEO of Rock Edge stated that, “We are very pleased with exploration results on the

Superb Lake Property and are looking forward to the next phases of exploration, which will help identify

additional pegmatites in the area and help trace the known dyke along strike. Until defined by drilling, the

dimensions of the spodumene bearing pegmatite as observed on surface may represent a minimum, given

the nature of the surrounding till cover.”
