About cesium and the cesium market

Cesium is the heaviest stable alkali metal with a unique set of characteristics due to its position on the periodic table. It is highly reactive, has excellent photoelectric properties and has a large ionic radius. It is the metal of choice across a number of applications, including atomic clocks, 5G infrastructure, defence targeting optics and next-generation green tech.

Cesium is defined as a critical metal by both Canada and the United States owing to its supply chain vulnerability. There is currently believed to be a significant shortage of cesium feedstock globally. The industry revolves around extreme supply concentration with the United States and several European allies being 100 per cent net import reliant for their cesium needs. Pollucite has historically been the mineral of choice for cesium extraction given its high cesium content.

About Lucy South:

• The Lucy South cesium deposit contains an open-pit measured resource for the lithium-cesium-tantalum zone of 51,500 tonnes at 2.58 per cent Cs2O and 1.47 per cent Li2O2; the LCT zone encloses a higher-grade cesium-rich pollucite zone containing a measured resource of 15,600 tonnes at 5.19 per cent Cs2O and 1.76 per cent Li2O:
  • Total contained metal in the measured category of 1,322 tonnes Cs2O.
• This resource is believed to be the second-largest cesium resource in active development in the Western world.
• The resource is contained within a highly fractionated LCT pegmatite, the Lucy South pegmatite, and covers an area of approximately 120 metres by approximately 50 metres, and has an average depth from surface of approximately 20 metres.
• It is located 130 kilometres east of Winnipeg and 500 metres north of the TransCanada Highway. It is proximal to the intracontinental railway system and Manitoba's low-cost hydro-electric power grid.
• The resource is partly open along strike and downdip.

About Falcon West:

• The focus of the Falcon West joint venture between Grid (85 per cent) and Avenir (15 per cent) 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 kilometres 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.
• Exploration potential in the project area remains high with a number of occurrences of spodumene and pollucite mineralization noted in the immediate project area (the Artdon-Lucy target area) that extends for greater than one km along strike and greater than 500 metres across strike. 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 LCT pegmatites in the east.
• The company is also eyeing the potential for outlining additional cesium resources in the project area. Drilling is expected to commence in January, 2027, focused on expansion of the Lucy South resource and identifying new LCT pegmatites with cesium potential. A strong magnetic low anomaly interpreted to reflect a large volume of near-surface granitic pegmatite coincides with the Artdon-Lucy pegmatite trend and extends several km along strike in both directions.

Quality assurance and quality control

The company's continuing exploration program at the Falcon West cesium/lithium property is being supervised by Dr. Dave Peck, PGeo. Grid Metals applies best practice quality assurance and quality control 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, tagged and then transported by secure carrier to the Activation Laboratories facility in Ancaster, Ont., 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 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, Ont.

About Grid Metals Corp.

The company is one of the largest mineral rights holders in the province of Manitoba with over 250,000 hectares of mineral claims and exploration licences registered to Grid. The current focus of Grid is its Falcon West property, which is advancing toward commercial production following the release of a maiden cesium resource at the Lucy South deposit. A summary of Grid's mineral properties in Manitoba includes:

1. The Falcon West property (lithium-cesium) is located 130 km east of Winnipeg along the Trans-Canada Highway and contains an open-pit measured mineral resource at the Lucy South deposit of 51,500 tonnes grading 2.58 per cent Cs2O and 1.47 per cent Li2O2. The property is subject to a joint venture agreement with Avenir, which has a 15-per-cent interest in the property.
2. The Makwa property (nickel-copper-platinum-group-metal-cobalt), which is subject to an option and joint venture agreement with Teck Resources Ltd. Teck can earn an up-to-70-per-cent interest in Makwa by incurring a total of $17.3-million, comprising project expenditures ($15.7-million), and cash payments or equity participation ($1.6-million) with Grid. Makwa is located on the south arm of the Bird River greenstone belt and contains an open-pit indicated mineral resource of 14.2 million tonnes grading 0.48 per cent nickel, 0.11 per cent copper and 0.37 gram per tonne palladium.
3. The Mayville property (Cu-Ni) is located on the north arm of the Bird River greenstone belt. Grid owns a cumulative 89-per-cent interest in the project. The project contains an open-pit indicated mineral resource of 32.0 million tonnes grading 0.40 per cent copper, 0.16 per cent nickel and 0.13 g/t palladium.
4. The Donner property (Li-Cs) is adjacent to the Mayville property, and Grid owns 75 per cent of the project. The project contains an open-pit inferred mineral resource of 2.1 million tonnes grading 1.42 per cent Li2O and an underground inferred mineral resource of 4.7 million tonnes grading 1.37 per cent Li2O5.
5. The Thompson East (Cu-Ni-PGM) property is located east of the city of Thompson in north-central Manitoba and captures a number of high-tenor Cu- and PGE-rich magmatic sulphide occurrences that are interpreted to be related to the development of the adjacent Thompson nickel belt. The property is subject to an option and joint venture agreement with Boliden Mineral Canada Ltd. Boliden is currently sole-financing early-stage exploration on the property.
6. The 100-per-cent-owned Fox River (Cu-Ni-PGM-Au) property located in the Gillam region of northeastern Manitoba and covering 90 km of strike of the highly prospective Fox River belt -- a direct analogue to the Raglan nickel district in Northern Quebec.

All of the company's southeastern Manitoba projects are located on the ancestral lands of the Sagkeeng First Nation with which the company maintains an exploration agreement.
