HIGHLIGHTS 

• New spodumene bearing pegmatites zone discovered at the Ear Falls Project with grab samples up to 4.54% Li₂O. 

• Favorable geology and a highly fractionated sample located 2 km northeast of the new discovery spodumene zone suggest the potential for a minimum 3-km-long trend for exploration of spodumene bearing pegmatites. 

• The discovered spodumene-bearing pegmatites are located along a structurally controlled zone of 1 km in strike length, open in all directions. 

• Exploration plan has been submitted to Ontario's Ministry of Mines for a stripping and a drilling program in October. 

• Ear Falls Project was expanded from 3,375 ha to 20,623 ha (~600% expansion) upon the successful discovery of the new spodumene bearing pegmatites zone for a cash cost per hectare of only $7.98. 

• The eastern expansion of the project provides a new exploration opportunity to search for a potentially identical geological system.

Winnipeg, Manitoba--(Newsfile Corp. - September 17, 2023) - Beyond Lithium Inc. (CSE: BY) (OTCQB: BYDMF) (the "Company" or "Beyond Lithium") is pleased to announce the discovery of a new spodumene-bearing pegmatite zone at its 206 sq. km Ear Falls Project in Northwest Ontario. Grab samples have assayed up to 4.54% Li₂O and a minimum 3-km-long prospective trend has been identified. A highly fractionated sample located 2 km northeast of the spodumene pegmatite zone establishes a minimum of 3-km-long trend for spodumene bearing pegmatites exploration.

Upon making this new discovery, Beyond Lithium strategically expanded the Ear Falls Project from 3,375 ha to 20,623 ha (~600% expansion) in area (Figure 1).

The Ear Falls Project, previously referred to as the Wenasaga Property, is located right outside the town of Ear Falls, 70 km south of Red Lake and 145 km north of Dryden in Northwest Ontario. Ear Falls has excellent infrastructure including highway and logging road access, power lines, services, and local labour.

Mr. Lawrence Tsang, VP Exploration for Beyond Lithium, commented, "This spodumene discovery is significant as it occurs within a 13-km-long metasedimentary-granite structural corridor where there's opportunity for more discoveries as we ramp up exploration. We are targeting subparallel spodumene pegmatite dykes along the main metasedimentary-batholith structure and the major regional fault. Exploration on the eastern expansion of the project also provides an opportunity to search for a potentially identical geological system."

Mr. Tsang added that, "Exploration at the Ear Falls Project is ongoing, and we have already submitted an exploration plan with Ontario's Ministry of Mines to carry out a stripping and a drilling program to further delineate the spodumene pegmatites zone. The stripping and drilling program is targeted to commence in October."

Allan Frame, President & CEO, commented that, "This exciting news supports that new discoveries are possible outside of the remote regions of northern Quebec and Ontario. With just three months into our 2023 exploration program trying to cover all 64 projects with over 150,000 ha in area, Beyond Lithium has made two major discoveries in Ontario: the Allen Graeme pluton at Cosgrave and this new high grade spodumene bearing pegmatites zone at the Ear Falls Project. This early success shows the effectiveness of our exploration program. Many assay results remain to be received and announced and we are confident in delivering additional positive results before the end of the year."

Mr. Frame added, "In a recent news release I mentioned that it is important for our shareholders to keep in mind that while we are as anxious as they are to share all assay results as they come in, it is sometimes a better course of action to first consolidate our land position either through staking, optioning or both in certain districts. I am proud to report that this approach has allowed us to acquire 17,233 additional hectares around the discovery announced today at an average cash cost of $7.98 per hectare and the issuance of only 300,000 shares."

The finding of the spodumene pegmatites zone by Beyond Lithium at the Ear Falls project is a brand-new discovery in this region. Beyond Lithium recognized the potential of this area and was able to stake most of the prospective open grounds around the original claims and consolidated additional claims from a few prospectors to assemble a contiguous project of 20,623 ha in area.

The expansion has delineated two high priority areas for exploration associated with the labels in Figure 3 below:

1. Explore along the main metasedimentary-batholith structure and the major regional fault and look for subparallel spodumene pegmatite dykes.

2. Explore for additional prospective structure along the newly mapped metasedimentary-batholith in the northwest and look for additional spodumene pegmatite dykes.

Background of the spodumene discovery

The Phase 1 exploration program at the Ear Falls Project was completed in June. We have since updated the geology of the project and more significantly located the batholith-metasedimentary contact within the project as this contact is probably the preferential structure for LCT pegmatites (Figure 4). After discovering the spodumene pegmatites zone, Beyond Lithium's field team further explored along this metasedimentary-batholith contact and was able to locate three new beryl bearing pegmatites (Figure 4).

Subparallel spodumene bearing pegmatites along a minimum of 1 km strike length were discovered along the main logging road of the Ear Falls Project up to 6 meters wide in exposed outcrops (Figure 6). The spodumene pegmatites are hosted in both granite and metasediment trending generally at 40 to 60 degrees following the regional foliation with local variabilities. These spodumene pegmatites are covered by a thin layer of vegetation. A follow-up stripping program has been planned to include the removal of the overburden to further outline the true thickness and the density of these spodumene pegmatites.

Sampling and assay results

A total of 205 individual pegmatite outcrops have now been mapped along the main structural corridor to date illustrated as blue dots in Figure 8 and we have collected 68 samples at the project. So far, 48 of the samples have received assays. From the 48 assays, four samples were taken from the spodumene pegmatites zone with Li₂O ranging from 0.76% to 4.54% and cesium ranging from 32.83 ppm to 68.97 ppm (Table 1). More samplings including channel sampling are planned on the beryl and the spodumene pegmatites by the end of September to early October to further outline the lithium bearing zone.

A couple of samples, E00105586 and E00105888, were collected just meters away from the spodumene pegmatites in the granite and metasediment host rocks. These two samples in the host rocks show significantly elevated Cs, 134 ppm and 636 ppm, and Li ,408 ppm and 1407 ppm, respectively (Table 2). In addition, the Cs values in the host rock or the alteration halo of the spodumene mineralization (134 and 636ppm Cs) are much higher than the Wenasaga Lake batholith (average of 7ppm Cs) implies the melt is highly enriched in incompatible rare elements and volatiles for the formation of lithium bearing pegmatites which has gone through a high level of fractionation (Breaks 2003) (Figure 7). This geochem baseline in the host rock with elevated Cs and Li could be the alteration halo signature of the spodumene pegmatites at the Ear Falls Project. This signature would be a great exploration tool for exploring blind target in the area.

Geological interpretation

Cesium versus K/Rb variation in samples is a common and convenient diagram to display the fractionation trend or the relative degree of evolution of S-type, peraluminous granites and related pegmatite granites and the rare-element pegmatite groups that fractionated from the parent granitic rocks. With increasing fractionation of the pegmatite-forming melt, the compositions of the potassium feldspar and mica become more enriched in rubidium and cesium thus the fractionation trend point to the lower right corner in the plot as the higher fractionated area. By plotting up the K/Rb vs Cs values of the 48 completed assays, a distinctive fractionation trend progresses from the SW to the NE orientation with an increase in Cs and a decrease in K/Rb ratio (Figure 7). One sample, E00105574, is plotted in the higher fractionated quadrant of the plot and this sample is located 2 km northeast on trend of the spodumene zone (Figures 2 & 3).

Regional geological context

The Ontario Geological Survey's released collected data in 2002 and outlined a couple of 1.1% and 1.2% A/CNK ratio samples in the eastern expansion of the Ear Falls project which suggested the presence of a nearby fertile pluton (Tindle 2002). Based on LCT pegmatites literature, a molecular ratio [Al2O3/(CaO + Na2O + K2O)] is commonly used to indicate whether a sample or a stock/pluton is mildly peraluminous (A/CNK = 1.0 to 1.1) or strongly peraluminous (A/CNK > 1.2) (Tindle 2006). These mildly to strongly peraluminous A/CNK samples also coincide with an area of elevated deep lake sediment in lithium just situated northeast from the Ear Falls project (Figure 8). This eastern expansion could be a new area to explore for a separate system than the new spodumene pegmatites zone associated with the Wenasaga Lake batholith and the Sandy Creek beryl pegmatites group.

Beyond Lithium acknowledges the effort and work preformed by the project vendors, Bounty Gold Corp and Last Resort Resources, that led to the first discovery of its kind around the fertile Wenasaga Lake batholith and provides a proof of concept for the methodology used to assemble for the 64 prospective projects. Notably, Beyond Lithium's Ogani Lake Project is located just 30 km northeast of the Ear Falls Project and 65 km west of Green Technology Metals' Root and McCombe Lithium deposits. The Ogani Lake Project was also recently expanded from 1,427 hectares to 5,177 hectares after beryl was found in several white tourmaline-muscovite pegmatites up to 10 meters wide during Beyond Lithium's phase 1 program (Figure 9).

Regionally, the Wenasaga Lake batholith was described as a S-type fertile pluton which is likely the parental pluton of the Sandy Creek beryl pegmatites. The Sandy Creek beryl bearing pegmatites that were discovered in the early 1960s are located 7 km southwest of the new spodumene pegmatites zone (Breaks 1993). Very limited to no exploration work was done in the area since the discovery of the Sandy Creek beryl pegmatites for over 60 years. Beyond Lithium recognized this area to be favourable for LCT pegmatites because there are a well-established Wenasaga Lake batholith as the potential source of LCT pegmatites of the area and the higher fractionated Sandy Creek beryl occurrence in the area that led Beyond Lithium's field crew discovering the new spodumene pegmatites zone.

Based on the geochem plot of the 2023's collected samples in comparison with the batholith and the Sandy Creek beryl pegmatites (Figure 7), the Wenasaga Lake batholith is likely the parental pluton of the new spodumene bearing pegmatites zone. The batholith was mapped concordant to the Uchi-English River sub provincial boundary covering approximately 260km2 in area (Breaks 2003). The Sandy Creek beryl bearing pegmatites were noted to follow this regional foliation orientation of the host metasedimentary rock (Breaks 1993). This regional NE structure is an ideal host and fluid pathway for the formation and fractionation of LCT pegmatites as most LCT pegmatites deposits in the world have some sort of structural control for its formation (Bradley 2017).

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). Samples with lithium overlimit (>10,000 ppm Li) are analyzed with another Four-Acid Digestion with higher detection limit of up to 10% Li. Batches of samples with overlimit >10,000 ppm or 1% Li are analyzed with Sodium Peroxide Fusion for validation. 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.
