Grid Metals Announces Positive Mineralogical Results at Falcon West, Engages SGS Canada for Ore Sorting Test Work, and Announces Investor Relations Agreements

Grid advances Falcon West cesium evaluation with ore sorting tests while expanding investor relations efforts via two new TSXV‑subject agreements.

Rhea-AI Summary

Grid Metals (MSMGF) reported positive mineralogical results from the Lucy South pegmatite at its Falcon West Property in Manitoba, confirming pollucite as the dominant cesium-bearing mineral and initiating ore sorting test work. An initial >300 kg composite sample is being shipped to SGS Canada for grinding, blending and assay, with three size fractions to be tested by Tomra in Germany using XRT ore sorting to evaluate Cs2O recoveries and concentrate grades. Mineralogical analyses of 28 drill core samples show a strong positive correlation between Cs2O grade and pollucite content in the Lucy South pollucite zone, with about 30% Cs2O corresponding to roughly 80% pollucite. Pollucite is also identified at Lucy North. Grid aims to assess the potential to produce a saleable 10–20% Cs2O pollucite concentrate. The company also signed 12‑month and 6‑month investor relations agreements with Peterson Capital and Capital Analytica, respectively, involving cash fees and 200,000 stock options, both subject to TSXV approval.

Positive

• Pollucite confirmed as dominant cesium mineral at Lucy South, supporting potential cesium concentrate production
• Strong Cs2O–pollucite correlation (R=0.98) in Lucy South pollucite zone, with ~30% Cs2O equating to ~80% pollucite
• >300 kg composite sample being tested by SGS and Tomra to evaluate Cs2O recoveries and concentrate grades
• Ore sorting study targets 10–20% Cs2O saleable pollucite concentrate range
• Falcon West joint venture structure gives Grid 85% interest in a cesium‑focused project in a critical metal

Negative

• Peterson Capital investor relations contract costs C$100,000 over 12 months, paid from cash reserves and subject to TSXV approval
• Capital Analytica agreement costs C$150,000 for six months, with an optional C$75,000 extension and 200,000 stock options
• Ore sorting and metallurgical work are early‑stage tests with no disclosed economic study or production decision

News Explained

The agreements specify $100,000 and $150,000 cash fees plus 200,000 options, subject to TSXV approval and future grant terms.

The agreements disclose cash fees of CDN$100,000 for Peterson Capital and $150,000 for Capital Analytica, adding specified company spending to the previously disclosed investor-relations arrangements and a prospective ownership-related item.

Peterson's fee is $65,000 up front and $35,000 after six months, while Capital Analytica's fee is payable in two tranches and may be followed by a six-month $75,000 renewal.

Capital Analytica is entitled to 200,000 stock options within two months, with terms still to be determined; both agreements remain subject to TSXV approval, so the option grant is not yet a completed issuance.

The named checkpoints are TSXV approval, the two-month option-grant window and Peterson's deferred payment after six months; these resolve the timing of the disclosed approval, ownership and cash-payment items.

TORONTO, ON / ACCESS Newswire / September 8, 2026 / Grid Metals Corp. (TSXV:GRDM)(OTCQB:MSMGF) ("Grid" or the "Company") is pleased to report positive mineralogical results from the Lucy South pegmatite at its Falcon West Property (the "Property") in southeastern Manitoba. The results confirm pollucite, the preferred mineral for cesium processing, as the main cesium host mineral at Lucy South. Accordingly, Grid has engaged SGS Canada to complete an initial >300 kg ore sorting test program to determine the potential of producing a marketable cesium-bearing pollucite concentrate. Ore sorting using X-Ray Transmission ("XRT") is the preferred method to recover pollucite from ore and is a well-proven approach in the industry. This ore sorting test work will allow Grid to supply pollucite concentrate to potential end users to test the amenability of the concentrate for cesium chemical production.

Highlights

• Pollucite is the dominant cesium-bearing mineral in the Lucy South pegmatite.

• Strong liberation performance from the planned ore sorting (XRT) tests are expected based on the mineralogical and grain size data.

• A strong positive correlation within the Lucy South pollucite zone exists between Cs₂O grade and pollucite content (linear regression correlation coefficient = 0.98) with 30% Cs₂O equating to 80% pollucite.

• Pollucite is also present in the Lucy North pegmatite.

• A metallurgical study applying ore sorting technology will soon commence. The study will help constrain the potential of producing a saleable Cs₂O (pollucite) concentrate having a grade in the range of 10-20% Cs₂O.

Mineralogical Results

A total of 28 drill core samples from the Artdon and Lucy pegmatites have been analyzed using QEMSCAN and MLAS semi-quantitative analysis. The analyses were performed at two different laboratories over a period of 12 months. Twenty-four samples are from Lucy South. Of these, 15 samples are from the pollucite zone, one from the spodumene zone, one from the lepidolite zone, one from the aplite zone, one from the wall zone, and 5 from the external contact zone where it features intense biotite alteration and enhanced cesium contents. Three samples were analyzed from the Lucy North pegmatite. One sample was analyzed from the Artdon pegmatite. Results are presented in Table 1 below.

Results for the Lucy South pegmatite samples indicate that pollucite is by far the dominant Cs-bearing phase in the pollucite zone. The only other Cs-bearing phases identified within the pollucite zone are muscovite and, to a lesser extent, biotite. Samples from Lucy South from the adjacent spodumene, wall, aplite and lepidolite zones do not carry significant quantities of pollucite. In contrast, some samples from the biotite-rich portions of the contact zones can locally contain pollucite.

Ore Sorting Test Work

• With its high concentration of cesium (can contain greater than 30% cesium oxide), pollucite is the mineral of choice for extraction of cesium for processing into value-added cesium chemicals.

• An initial >300 kg composite sample is being shipped to SGS Canada (Lakefield, Ontario) for grinding, blending and assay. Three size fractions will be produced. These will be shipped to the Tomra ore sorting test facility in Germany in order to determine Cs₂O recoveries and concentrate grades for each fraction.

• Additional mineral concentration test work is being considered for the fall.

• A microprobe study to determine the chemistry and chemical variability of the pollucite in the concentrates is also being considered.

About Falcon West

• The focus of the Falcon West joint venture between Grid (85%) and Avenir Minerals Limited (15%) is to establish a producing cesium operation at the Lucy South cesium zone. Cesium is a rare critical metal with a number of forward-facing industrial uses. The scope of the project is to establish a small footprint operation that uses crushing and XRT ore sorting (no water utilized or extensive infrastructure) in the production of a cesium-bearing pollucite concentrate to be sold to downstream cesium chemical producers.

• Falcon West consists of 124 unpatented mining claims located 130 km east of Winnipeg and is transected by the Trans Canada Highway. Most of Grid's exploration efforts have focused on the Lucy claims in the northeastern part of the property.

• Starting in October 2025, Grid commenced resource delineation drilling for cesium and lithium targeting the core zone of the Lucy South pegmatite located at the eastern end of the ADL trend. This campaign concluded in February 2026.

• The Lucy South pegmatite is a ~10 metre-thick, near surface, highly fractionated cesium-lithium-tantalum-enriched pegmatite body containing a discrete pollucite-rich zone (Lucy South cesium zone). Resource drilling has defined this cesium zone over an area of ~120 metres x ~50 metres. The known pollucite mineralization occurs over a true thickness of <1m to 4 metres. The zone remains partially open to the north, east and south.

• The pollucite mineralization is interpreted to have formed in the partially crystallized core zone during the last stages of solidification of the host Lucy South pegmatite, post-dating an overlapping and more continuous zone of spodumene mineralization.

• Exploration potential in the project area remains high with a number of occurrences of spodumene and pollucite mineralization noted in the immediate project area of >1 km by ~250 metres. Of note is a large gap in historical drilling between the Artdon LCT pegmatite occurrence in the west and the Lucy South and Lucy North pegmatites in the east. This 800-metre-wide gap remains a high priority target for the next phase of drilling at the Property.

About Cesium and the Cesium Market

Cesium is defined as a critical metal by both Canada and the U.S. It is used in a number of important energy and security related applications. There are currently no western controlled cesium producing operations in the world. There is currently believed to be a significant shortage of cesium feedstock globally¹. Pollucite has historically been the mineral of choice for cesium extraction given its high cesium content.

Quality Assurance and Quality Control

The Company's ongoing exploration program at the Falcon West cesium/lithium property is being supervised by Dave Peck, P.Geo. Grid Metals applies best practice quality assurance and quality control ("QAQC") protocols on all of its exploration programs. For the current program, all core was logged and sampled at the Company's core facility located on its Makwa nickel property. Generally, 1.0 metre sample lengths were used. Samples were bagged and tagged and then transported by secure carrier to the Activation Laboratories facility in Ancaster, Ontario for sample preparation and analysis for lithium, cesium, rubidium, tantalum and selected major and trace element abundances using a sodium peroxide fusion total digestion method followed by ICP-OES and ICP-MS analysis. The Company is using two rare metal certified reference materials ("CRMs") and an analytical blank for the program to monitor analytical accuracy and check for cross contamination between samples. The blank and CRM results for the reported intervals were determined to fall within the accepted range of deviation from the certified values. A check assay program using a similar sodium peroxide fusion digestion method has recently been initiated with check samples being analyzed at AGAT Laboratories in Thunder Bay, Ontario.

FAQ

What specific ore sorting and metallurgical work is Grid Metals planning at Falcon West?

An initial composite sample exceeding 300 kg from Falcon West is being shipped to SGS Canada in Lakefield, Ontario for grinding, blending and assay. Three size fractions will be produced and sent to the Tomra ore sorting test facility in Germany to determine Cs2O recoveries and concentrate grades for each fraction. The company is also considering additional mineral concentration test work in the fall and a microprobe study to assess pollucite chemistry and variability in the concentrates.

Capital Analytica is also entitled to a grant of 200,000 stock options within two months of entering into the agreement, and the agreement remains subject to TSXV approval.

What is the development concept for the Falcon West cesium project?

The Falcon West joint venture, owned 85% by Grid and 15% by Avenir Minerals, focuses on establishing a producing cesium operation at the Lucy South cesium zone. The project concept is a small‑footprint operation using crushing and XRT ore sorting without water or extensive infrastructure to produce a cesium‑bearing pollucite concentrate for sale to downstream cesium chemical producers.

How extensive is the exploration work and resource delineation at Lucy South so far?

Resource delineation drilling for cesium and lithium at the Lucy South pegmatite started in October 2025 and concluded in February 2026. The Lucy South pegmatite is approximately 10 metres thick, near surface, and highly fractionated, with a discrete pollucite‑rich cesium zone defined over an area of about 120 metres by 50 metres. Additional occurrences of spodumene and pollucite mineralization have been noted over an area exceeding 1 km by ~250 metres, including an 800‑metre drilling gap between the Artdon and Lucy pegmatites that is a high‑priority target for the next phase of drilling.

What quality assurance and quality control measures are applied to Falcon West drilling samples?

Grid’s exploration program at Falcon West is supervised by a Qualified Person, Dr. Dave Peck, P.Geo. Core is logged and sampled at the company’s core facility, generally in 1.0 metre intervals, then sent to Activation Laboratories in Ancaster, Ontario for sodium peroxide fusion total digestion followed by ICP‑OES and ICP‑MS analysis for lithium, cesium, rubidium, tantalum and selected elements. The company uses two rare metal certified reference materials and an analytical blank to monitor accuracy and contamination, and has initiated a check assay program at AGAT Laboratories in Thunder Bay using a similar digestion method.
