Case Lake District Projects
Summary
The Case Lake District Projects are comprised of three projects, the Case Lake North (7,476 ha), the Case Lake South (2,711 ha), and the Stimson (1,631 ha), totaling 11,818 ha in area. The three projects have good access to most parts of the properties.
All three projects are located around the prospective Case Lake Batholith which is a fertile source for the rare-earth (lithium, cesium, and tantalum) mineralization in the Case Lake District; A/CNK of the Case Lake Batholith ranges from 1.0 to as high as 3.0 where A/CNK = 1.0 to 1.1 is mildly peraluminous and >1.2 is strongly peraluminous the higher the aluminum content, and the greater the abundance of AL-rich minerals, such as garnet and muscovite.
In addition, the Case Lake North and the Case Lake South Projects are situated along trend of Power Metals Corp. (PWM.V) discovered spodumene-bearing pegmatites and next to RT Minerals (RTM.V) announced east-west trending pegmatitic dykes.
The Stimson Project has nine historical drill holes completed in the southern part of the project hosted in the metavolcanic with one of the holes, PT 94-11, intercepted two intervals of 30m wide noting with “Pegmatite contains green feldspar (spodumene or microcline)”.
(note: no historical drill cores available for relog and require relocation of the historical collar for further review and confirmation)
Exploration
- Continue to prospect and explore the three projects with mapping and sampling to establish a background geochemical database to key into areas with higher exploration potential.
- Relocate the historical drill holes at the Stimson Project and prospect around the area where the historical “pegmatites” would project on surface.
Gathering Lake Project
Summary
The Gathering Lake Project is comprised of three properties, the Gathering Lake South (3,864 ha), the East (986 ha), and the West (2,098 ha) properties, totaling 6,948 ha; the three properties are less than five kms from each other that can be accessed by trucks and ATVs. The Gathering Lake Project is located in the Georgia Lake District that is well known for lithium and spodumene mineralization next to:
- Balkan Mining’s (ASX: BMM) Gorge Lithium Project with spodumene mineralization up to 3.22% Li2O at Nelson and up to 2.88% Li2O at Koshman showings.
- Tearlach Resources’ (TEA.V) Georgina Property with spodumene mineralization up to 4.04% Li2O over 0.70m from a channel sample (see press release dated November 28, 2023 from Tearlach Resources (https://www.accesswire.com/viewarticle.aspx?id=810467&token=82fito391y0i58fbeufi)
Exploration
In the 2023 exploration program completed by Beyond Lithium, a total of 56 samples were collected in the Gathering Lake area with 12 samples are still pending for results. Two muscovite samples yielded up to 1,477 and 2,075ppm Li with 31 and 35 K/Rb ratio respectively in the northwest corner of the Gathering South Property and another muscovite sample returned 865ppm Li and 51 K/Rb ratio in the southern pegmatite of the Property. To date, over 640 data waypoints have been collected and compiled from the Phase 1 program to further map out the area and define the metasedimentary contact with the Glacier Lake Batholith as the contact acts as the structural conduit for pegmatites formation.
The overall lithium values in pegmatites collected from the 2023 exploration program range from 100 to 200ppm Li and up to 1,477 and 2,075ppm Li in two muscovite samples from pegmatite with K/Rb ratio ranges at about 50-60 show significant elevated lithium program to warrant for a follow up exploration program:
- More sampling and mapping across the Gathering Lake South Property keying in along trend of the highly elevated lithium samples in muscovite-bearing pegmatites.
- Establish a lithium zonation or trend in the Gathering South area.
- Continue to prospect along other metasediment-granite contact structures.
- Explore along the metasediment-granite contact structure that extends to Tearlach Resources’ (TEA.V) spodumene-bearing pegmatites.
Wisa Lake Project
Summary
The Wisa Lake Project comprises of 6,666 ha in area is located in the southwest part of Ontario that can be accessed by trucks and atvs. The Project is also next to Green Technology Metals’ (ASX: GT1) Wisa Project and to Libra Lithium Corp.’s Flanders Project.
- Green Technology Metal’s (ASX: GT1) pegmatites generally run E-W orientation that have been mapped for 1.5 km along strike with widths exceeding 20 m locally. Initially, the mapping and sampling delineated the pegmatite with elevated tantalum in the west and lithium in the east.
- Libra Lithium Corp announced the discovery of spodumene-bearing pegmatites at the Flanders South Project with surface grab samples returning up to 2.86% Li2O within the newly named Homer pegmatite, which spans up to 35 m in width and is located less than 3 km from an all-season road.
Exploration
The 2023 Phase 1 exploration program was shortened due to forest fire in Ontario. Yet, the few days the field crew spent at the Wisa Lake Project were able to locate several pegmatites and a few of them were beryl-bearing. It is recommended that a follow up program should be carried out to further map out and sample across the project area to define and narrow down areas with higher exploration potential. Also, a LiDAR survey was completed in 2023 to outline topographic high features for the follow up exploration program to prospect.
Mavis Lake District Projects
Summary
Beyond Lithium has six projects as the Mavis Lake District Projects totaling 11,711 ha in area in the Dryden-Mavis Lake District including the Webb West (625 ha), the Webb East (2,934 ha), the Laval (1,042 ha), the Gullwing-tot (645 ha), the Satellite (1,287 ha), and the Temple Bay (5,178 ha) projects located next to the Mavis Lake Lithium Project owned by Critical Resources (ASS: CRR) that has a defined resource of 8Mt at 1.07% Li2O. Projects in this district can be easily accessed by trucks via nearby highway and are close to the town of Dryden, Ontario, with excellent existing infrastructures. In addition, the Mavis Lake District Projects are located within 100km to Beyond Lithium’s two spodumene projects – the Ear Falls Spodumene Project and the Victory Spodumene Project.
Exploration
The Mavis Lake District Projects are located along the subprovince boundary and subparallel regional fault structure associated with the regional Glacier Lake Batholith. The Glacier Lake Batholith is the main source of several fertile plutons identified in the areas including the Bottle Bay Stock at the Temple Bay Project, the Laval Lake Stock at the Laval Project, and the Gullwing Lake Batholith in between the Webb West, the Webb East, and the Gullwing-Tot Projects.
In 2023, Beyond Lithium’s technical team visited all six projects in the Mavis Lake District. All projects returned with mapped pegmatites and grab samples with elevated lithium up to 402ppm Li and 99ppm Cs and K/Rb as low as 40. More importantly, most of the elevated lithium samples (>50ppm Li) coincides with the overall regional mineralization trend at NE-SW signifying the correlation between the regional and the property scale mineralization trend. Based on the results and data collected from the 2023 exploration program, several exploration targets or trends are delineated at the six projects for follow up in the next exploration program.
Superb District Projects
Summary
The Superb District Projects are comprised of the Superb Project (2,321 ha), the Maytham Project (9,825 ha), the Sollas Project (6,521 ha), and the Linklater Project (2,504 ha) with access via logging roads. Regionally, the Superb District Projects are located along the English River and Winnipeg River subprovinces boundary as the main regional structure which has several fertile plutons and lithium occurrences identified along this region. This boundary zone has rare-element mineralization discovered over a 130 km long corridor between the Linklater Lake Project and the Superb Lake Project including Green Technology Metals (ASX: GT1) Seymour Lake and Junior Lake Projects and Rockedge’s (RDGE.V) Superb Lake Project with spodumene pegmatites grading 1.77% to 4.03% Li2O.
More importantly, the rare-element mineralization in this region has not been investigated in detail since the 1950s with the exception of the Superb Lake spodumene pegmatite (Stott and Parker 1997). In the 2023 exploration season, Beyond Lithium deployed field team prospecting all four projects and was able to identify pegmatites on each of them. The pegmatites samples returned with elevated anomalous lithium >50ppm clusters running subparallel to the regional structure (subprovince boundary).
Exploration
The Superb Lake and the Maytham Lake Projects including the nearby the Linklater Project and the Sollas Project all have elevated Li and Cs samples collected along the similar trend of the regional spodumene pegmatite trend generally striking NE-SW. This elevated Li and Cs should be re-visited in the next exploration program.
Superb Lake Project
- Re-examine the highly fractionated area in the NE corner of the project with detailed mapping and more sampling.
- Follow up areas that are on trend of Rockedge’s spodumene pegmatite.
- Follow up on the potential subparallel elevated Cs and Rb samples area.
Maytham Lake/Sollas Lake/Linklater Projects
- Re-examine the elevated Li, Cs, and Rb samples area.
Frontier District Projects
Summary
The Frontier District Projects is comprised of Borland East** (175 ha), Borland North** (1,012 ha), Borland West (351 ha), Favourable Lake (682 ha), North Trout (3,490 ha), Margot Lake (1,393 ha), and MacDowell Lake (4,137 ha) located in the northwest Ontario along the same regional structure that hosts the Pak and Spark lithium deposits owned by Frontier Lithium (FL.V). The PAK deposit has a probable mineral reserve of 4 MT averaging 1.79% Li2O; the deposit hosts a rare technical/ceramic grade spodumene with low inherent iron (below 0.1% Fe2O3). The Spark Deposit has a probable mineral reserve of 18 MT averaging 1.5% Li2O.These projects are mainly accessed by helicopter with local logging roads.
**Optioned to Patriot Lithium (ASX: PAT), please see press release dated January 10, 2024, for details: https://beyondlithium.ca/beyond-lithium-enters-property-sale-agreement-with-patriot-lithium-for-borland-claims
Exploration
The Bear Head Lake Fault Zone appears to be the locus for a peraluminous suite of granitic plutons. To date based on research in the region, nine major plutons consisting of two mica granites (fertile granites) are documented over the 140 km strike length of the fault; fertile granites are interpreted to be the parental rocks that give rise to rare metal pegmatites. Also, the Bear Head Lake Fault Zone also acts as a subprovince boundary between the Berens River and Sachigo Subprovinces, two of the greenstone belts are located and divided by this structure. The Favourable Setting Net Lakes greenstone belt is hosted to the northeast of the boundary and the North Spirit Lake greenstone belt is hosted to the southwest of the boundary.
The presence of the regional Bear Head Lake Fault Zone and of the two greenstone belts has made this region to be favorable for LCT pegmatites exploration. The seven projects in the Frontier District are located along this structure. Beyond Lithium’s field team only prospected the Margot Lake Project for 2 field days in 2023 due to the shortage of helicopter access from forest fire in Ontario. Prospecting programs are planned to explore the Frontier District Projects in the next exploration program.
