RT MINERALS CORP. HIGHLIGHTS GROWING INTEREST IN THE CASE BATHOLITH REGION AMID INCREASED GLOBAL INVESTMENTS

RT Minerals Corp. has highlighted the growing exploration and development activity in the Case Batholith region, a large intrusive geological formation spanning approximately 150 kilometres by 60 kilometres in Northeastern Ontario. The Case Batholith includes the Case Lake area, which has seen significant investment from multiple major mining companies focused on exploring its rich mineral potential, particularly for lithium, cesium and rare earth elements. RT Minerals holds a strategic property position adjacent to several of these key industry players. A neighbouring company to RT Minerals holds a market capitalization exceeding $200-million, while another nearby company has an approximate market capitalization of $70-million. The presence of well-capitalized exploration and development firms in the Case Batholith region underscores the growing investment interest and potential of this emerging critical mineral district.

The Case Batholith has become a focal point for critical mineral exploration, with a growing number of major mining companies securing substantial investments aimed at advancing exploration and development. This influx of capital highlights the increasing global demand for resources such as lithium and cesium, and RT Minerals is strategically positioned to capitalize on the momentum building in the region.

Strengthening demand for exploration in the Case Batholith area

The surge of global capital into neighbouring properties reflects the rising demand for battery metals and rare earth elements, which are key to the transition to a low-carbon economy. As large-scale exploration and development projects gain momentum in the area, RT Minerals is well positioned to benefit from the increased interest and advancing infrastructure in the region.

Chief executive officer Alson Niu commented: "The Case Batholith is rapidly becoming a critical region for the exploration of essential minerals. With several major players already heavily invested in the area, RT Minerals is well positioned to leverage this growing momentum. We believe our property holds significant potential for lithium and cesium mineralization, and we are actively refining our exploration plans to unlock its full value."

Cesium: a critical mineral with limited global supply

Cesium is designated as a critical mineral by Canada and the United States, meaning it is essential for economic and national security but has a vulnerable supply chain. This soft, silvery-gold alkali metal is primarily extracted from pollucite, a rare mineral found in pegmatitic formations similar to those within the Case Batholith. Cesium's applications are specialized and essential across multiple high-technology industries:

• Aerospace and defence: Cesium-based compounds are used in spacecraft, satellite technology and military-grade positioning systems.
• Telecommunications and GPS: Cesium atomic clocks provide the world's most precise timekeeping standards, critical for GPS navigation and telecommunications networks.
• Medical and industrial uses: Cesium compounds are used in radiation therapy for cancer treatment and in drilling fluids for oil and gas exploration.
• Quantum computing and artificial intelligence: Emerging technologies are increasingly utilizing cesium in next-generation computing and artificial intelligence advancements.

Global investment in cesium development

With China and Canada historically controlling the majority of cesium production, new discoveries are crucial for diversifying global supply chains. The significant investments pouring into the Case Batholith area, including the Case Lake region, emphasize the importance of securing North American cesium resources and reducing dependency on foreign supply.

Future outlook: RT Minerals and the Case Batholith opportunity

The Case Batholith, including the Case Lake area, is emerging as a key region for cesium exploration, and RT Minerals is well positioned to take advantage of the growing demand for this scarce and strategically important element:

• Expanding global demand and restricted supply make cesium one of the most valuable critical minerals.
• The Case Batholith, including Case Lake, is an underexplored region with significant potential for cesium-bearing pegmatites.
• RT Minerals' property in the area aligns with recent industry trends and government initiatives to secure domestic supplies of critical minerals.
