Grounded Lithium Upgrades 1.0 Million Tonnes of LCE to Measured & Indicated

Rhea-AI Summary

Grounded Lithium Corp. has announced the advanced recognition of 63 sections of the Company's holdings from Inferred mineral resources to Measured mineral resource and Indicated mineral resource. This upgrade represents approximately 1.0 million tonnes of lithium carbonate equivalent within the Kindersley Lithium Project area. The upgrade confirms the overall 4.2 million tonnes of LCE across the KLP.

Positive

• Grounded Lithium Corp. has upgraded 1.0 million tonnes of lithium carbonate equivalent to Measured and Indicated mineral resources. This represents approximately 24% of the total Inferred mineral resource and confirms the overall 4.2 million tonnes of LCE across the Kindersley Lithium Project area.

Negative

• None.

CALGARY, AB, Oct. 24, 2023 /PRNewswire/ - (TSXV: GRD) (OTCQB: GRDAF) - Grounded Lithium Corp. ("GLC" or the "Company") is pleased to announce the advanced recognition of 63 sections of the Company's holdings from Inferred mineral resources to Measured mineral resource and Indicated mineral resource ("M&I"). These category improvements represent approximately 1.0 million tonnes of lithium carbonate equivalent ("LCE") within our 4.2 million tonnes of reported Inferred resource within the Kindersley Lithium Project ("KLP") area. GLC is the first company in the Province of Saskatchewan to be recognized by an independent third party for Measured mineral resource in a lithium from brine project.

The breakdown of the reclassification of the Company's total resource base is detailed in Table 1 below. Additionally, Figure 1 outlines which Company controlled sections were reclassified to either Measured mineral resources or Indicated mineral resources.

Table 1 – Resource Classification by Category

Category	Sections	Pore Volume (106 M3)	Li (tonnes)	LCE (tonnes)	LHM  (tonnes)
Measured	31	1,310	96,940	516,000	586,000
Indicated	32	1,175	86,950	463,000	526,000
Total M&I	63	2,485	183,890	979,000	1,112,000
Inferred	237	8,085	598,292	3,184,000	3,620,000
Total	300	10,570	782,182	4,163,000	4,732,000

This current upgrade to M&I only involves 21% of the total sections comprising the KLP, yet the independent technical report upgrades 24% of the total Inferred mineral resource which speaks to the quality of the resource and the Company's vision to accumulate focused landholdings. This upgrade further confirms the overall 4.2 million tonnes of LCE across the KLP. This change to resource categories requires higher confidence levels in the resource estimation process that can typically result in an overall reduction in total volumes. This outcome supports our confidence in our original analysis and mapping, together with the quality of the resource. 

"From our inception, GLC's vision was to secure focused high quality resource rights in areas which aligned with our extensive geological model, incorporating a low-cost structure to drive compelling economics," commented Gregg Smith, President & CEO. "By moving only a minor portion of our overall resource base to the M&I categories, we have passed a key step in the overall commercialization of Phase 1 of the KLP. Quality resource produces quality economics, which also supports our project's resilience to volatility in commodity price."

The Measured portion of the resource is 516,000 tonnes LCE or 586,000 tonnes lithium hydroxide monohydrate ("LHM"). A Measured Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of Modifying Factors to support detailed mine planning and final evaluation of the economic viability of the deposit.

The Indicated portion of the resource is 463,000 tonnes LCE or 526,000 tonnes LHM. An Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.

Technical information contained in this press release comes from the technical report dated October 23, 2023 prepared by certain qualified persons at Sproule Associates Limited in compliance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101") (the "Updated Technical Report"). The Updated Technical Report will be filed on SEDAR+ and the Company's website within 45 days.

Upgrading a percentage of the Company's total LCE resource base to M&I provides further confidence in our efforts to commercialize the KLP. A critical next step in that regard is the preparation of a pre-feasibility study which under NI 43-101 requires the resource base, or portions thereof, to be independently assessed as M&I. Another key component of the pre-feasibility study will be the results of our field pilot, which the Company is currently advancing the concept and design.
