Phase 2 Exploration on 11km Prospective Corridor Underway
HIGHLIGHTS
Beyond Lithium discovers new LCT pegmatite intrusive stock - also known as a fertile pluton - at its Cosgrave Lake project.
Named the Allen Graeme ("AG") Pluton in recognition of those who contributed to the discovery.
Important implications:
Anomalous rare earth elements of the AG Pluton have similarities to other plutons in the Georgia Lake District (the Pine Portage pluton, the MNW pluton, and the Barbara Lake pluton). These three fertile plutons all have well established lithium pegmatites belts association1.
The AG Pluton is over 266 hectares in size which is comparable to the Pine Portage and the MNW plutons located in the Georgia Lake District.
Results from channel samples of two beryl pegmatites at the AG Pluton show (i) comparable geochemical values to other known fertile plutons, (ii) have similar Cs, Li, and Be values to those of the Tanco fertile pluton located at Bernie Lake, Manitoba2 and (iii) are elevated compared to the Glacier Lake batholith.
The size of the AG Pluton directly implies that it generated large amounts of concentrated fluids and volatiles and is the source of lithium and rare earth minerals in lithium pegmatite formations in the vicinity.Â
Cosgrave Lake project expanded through staking from 7,388 ha to 9,424 ha.
Phase 2 exploration program at Cosgrave currently underway. Focused on main NE and SW corridor that spans 11km of prospective ground around the AG Pluton.
Winnipeg, Manitoba--(Newsfile Corp. - August 1, 2023) - Beyond Lithium Inc. (CSE: BY) (OTCQB: BYDMF) (the "Company" or "Beyond Lithium") is pleased to announce the discovery of a new LCT pegmatite intrusive stock - also known as a fertile pluton - at its Cosgrave Lake project. The new discovery was named the Allan Graeme ("AG") Pluton in recognition of those individuals who played a significant role in its discovery. The Cosgrave Lake project was one of the earlier projects being prospected as part of Beyond Lithium's Phase 1 program. The discovery of the AG Pluton at the Cosgrave Lake project unlocks tremendous lithium exploration opportunities for Beyond Lithium.
Mr. Frame, President and CEO of Beyond Lithium, commented: "This discovery shares similarities with three significant lithium discoveries in the Georgia Lake District, namely the MNW pluton, the Barbara Lake pluton, and the Pine Portage pluton. These well-known fertile plutons in the district are associated with prolific lithium pegmatite belts. The AG Pluton at Cosgrave Lake therefore presents a significant opportunity for Beyond Lithium. The size and geochemical characteristics of the AG Pluton indicate its potential as a source of concentrated fluids, volatiles, lithium, and rare earth minerals, making it an exceptionally promising area for further exploration."
The Georgia Lake District illustrated in Figure 1 is the host of several well-known fertile plutons namely the MNW pluton, the Barbara Lake pluton, and the Pine Portage pluton. These well-established fertile plutons in the Georgia Lake district are associated with several prolific lithium pegmatite belts including the Imagine Lithium MNW, as well as the Georgia Lake belts and Rock Tech Lithium lithium belt.

"Beyond Lithium's technical team relied on field observations, assay results and other data to make this important new discovery," said Lawrence Tsang, Beyond Lithium VP of Exploration. "During a recent site visit with Technical Advisor and Sr. Geologist Graeme Evans, and Sr. Field Geologist Paul Baxter, we recognized that a distinctive beryl pegmatitic zone with an irregular and lobate contact to the Glacier Lake batholith located in the western part of the Cosgrave Lake project was essentially a complex and zoned pegmatitic fertile centre. These very coarse grained complex zoned muscovite and K-feldspar rich pegmatites contain beryl, alluaudite, fluorapatite and other good indicators like cordierite as the feeders for the potential of lithium pegmatites formation from the centre. These minerals demonstrate the exsolution of pegmatites forming melts from the parental pluton."
The AG Pluton covers an area of over 266 hectares, which is comparable in size to the MNW pluton (351 ha) and the Pine Portage pluton (311 ha). The analogous size of the AG Pluton to other fertile plutons strongly suggests that the AG Pluton has generated substantial amounts of concentrated fluids and volatiles, serving as the source of lithium and rare earth minerals in lithium pegmatite formations in the vicinity.

During the Phase 1 exploration program completed last month at the property, two beryl bearing pegmatites at the AG Pluton site were found and channel sampled for a total of 14 one-meter-wide samples.
"The channel sample results, and the AG Pluton's values are typical of the other fertile pluton located in the Georgia Lake District and are elevated compared to the Glacier Lake batholith," said Lawrence Tsang. He added, "The assay results also show that these channel samples are relatively anomalous even though located within the fertile pluton. Worthy of note is that the results are quite similar to the concentration in the Tanco granite pluton located at Bernie Lake, Manitoba2 (Figure 3)."

Allan Frame: "Following this important discovery at the Cosgrave Lake project, in order to secure the entire area, we expanded our footprint by 2,036 hectares through additional staking. With this expansion of the Cosgrave Lake project on the west side of the original property, we currently have an area of 9,424 hectares exploration with an 11 km prospective corridor along the NE and SW trend." He added: "Beyond Lithium's Sr. Field Geologist, Paul Baxter, is currently leading our team that is focused on detailed mapping and grid sampling around the AG Pluton."
The 11 km prospective corridor trends conformably to the sediments contact in the area mapped out by Paul Baxter (Figure 2). The main objectives of the Phase 2 exploration program at Cosgrave Lake project are:
- To define the limits of the new AG Pluton;
- To do step out and cross section traverse to outline the higher density of pegmatite trends;
- To utilize the LIBS analyzer to provide the field crew with instantaneous field data to locate the "hotter" or higher LIBS's Li, Cs, Ta, lower K/RB values to find the spodumene productive zone.

A total of 74 samples were collected as part of Phase 1 prospecting field program at Cosgrave Lake with the results shown in Table 2. Lawrence Tsang commented: "There is plenty of exploration potential to follow up especially around low K/Rb areas and elevated Li anomalies delineated in the NE part of the project (Figure 4)."
Mr. Tsang concluded: "The anomalous values of Li/Cs/Ta published today when combined with the visual observations during our recent site visit allow us to connect the different pieces of data together and correlate the Cosgrave Lake project's geological model with the classic petrogenesis model of LCT pegmatites. This model provides a fundamental trend for the field crew to continue exploring for the spodumene productive zone at the Cosgrave Lake project."

Quality Assurance/Quality Control
All collected rock samples were put in sturdy plastic bags, tagged, and sealed at site. Sample bags were then put in rice bags and kept securely before being sent by road transport or delivered by the crew supervisor to SGS's preparation facility in Red Lake or Sudbury, Ontario, for sample preparation. Pulps are analyzed at the SGS facility in Burnaby, BC. All samples are analyzed with Four-Acid Digestion/Combined ICP-AES/MS package (49 elements). The QA/QC protocol included the insertion and monitoring of appropriate reference materials, in this case high concentration and low concentration certified OREAS and CDN lithium standards to validate the accuracy and precision of the assay results.
