Eureka Lithium Crews Advancing Quickly Across the Tundra in Quebec’S Far North

Vancouver, British Columbia, July 18^th, 2023 – Eureka Lithium Corp. (CSE: ERKA) (OTC: SCMCF) (FSE: S580) (“Eureka Lithium” or “Eureka” or the “Company”), owner of the largest lithium-focused land package in the top third of Quebec known as Nunavik, is pleased to report that field crews are making swift progress in Phase 1 exploration, focused on mapping and initial sampling, while encountering far more pegmatites than were mapped historically across more than 736 sq. km of Eureka claims in the New Leaf Lithium Camp (refer to July 6, 2023 news release) featuring the 326 sq. km ZigZag Property (see Figure 1) and three other claim blocks.

Mr. Jeffrey Wilson, Eureka President and CEO commented: “Our 15-person field crew, directed by our contracted GroundTruth Exploration partner, is off to a flying start across the tundra in Nunavik. Logistics, extremely important for this region, are being handled with military-style precision and the first major batch of samples is being submitted for assaying in the coming days. Pegmatites are abundant. We’re thrilled with the start of the program which bodes well for the upcoming first phase in the Raglan area, starting this month, where we hold highly strategic ground at Raglan West and Raglan South (see Figure 2).  Phase 1 across each area will prioritize potential lithium-bearing pegmatite zones for aggressive Phase 2 follow-up including initial drilling of the best targets.”

Technology-Driven Exploration

GroundTruth is utilizing a highly trained and experienced team of LCT Pegmatite prospectors who are investigating and sampling all known and newly located pegmatites in this under-explored region. Prospectors are navigating traverse routes using GPS enabled tablets loaded with all available data including Quebec geology, geochemistry, ArcticDEM and Multispectral Sattelite Imagery to vector precisely to outcrops and zones of highest potential.  Samples are being analyzed onsite with LIBS and XRF for lithium and pathfinder geochemistry for real-time follow-up during the program. Priority pegmatite zones encountered are being surveyed with UAV drone for Orthoimagery and DEM for a High Resolution 3D map of the pegmatite systems.  

Zig Zag Highlights:

• ZigZag is roughly 35 km SW/NE and averages 7 km SW/NE wide, increasing up to 20 km wide in the south part of the property;
• The claim block was only lightly mapped in the late 1990’s, indicating five major rock types;
• Intense lithium anomaly in lake sediments: 80 out of 140 (57%) historical samples (report GM6582) from non-government exploration returned >37.3 ppm lithium including 5 samples >70.6 ppm which would be in the top 21 of the Quebec government database comprising more than 30,000 samples. Eighteen of 30 government samples (60%) were in the 99^th percentile (>37.3 ppm) for lithium, coupled with strong cesium and rubidium footprints;
• Historical mag data for ZigZag shows prominent NW trending regional scale structures and an overall structural setting considered prospective for lithium-bearing pegmatite emplacement.

Cautionary Statement: Investors are cautioned that the lake bottom sediments information is taken from the publicly available sources in the Quebec government database. The Company has not been able to independently verify the information contained. The information is not necessarily indicative of the mineralization on the Property, which is the subject of this news release. There is no guarantee that significant discovery will be made as a result of its current exploration efforts.
