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 Property 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, four samples collected from a spodumene rich part of the dyke returned 1.77 % to 4.03% Li2O.

Highlights of Recent Exploration By Previous Operator

Channel Samples assays

During Medaro Mining Corp.'s (“Medaro”) previous exploration of 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: 
    1. Channel #1 - 0.43% Li2O across 3.2 meters; 
    2. Channel #2 - 0.65% Li2O across 3.8 meters; 
    3. Channel #3 - 2.47% Li2O over 3.2 meters; and 
    4. Channel #4 - 1.29% Li2O over 2.9 meters.

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 well 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 (VTEMTM 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.
