Rome Resources Reports High-Grade Tin Intercepts at Kalayi as Drilling Confirms Depth Potential

• Rome Resources has reported high-grade tin assay results from two diamond drill holes at its Kalayi prospect in the Democratic Republic of Congo. The drilling was part of an ongoing exploration program at the company's flagship Bisie North Project.
• The results confirm the presence of high-grade tin mineralization across multiple sub-parallel ore shoots at Kalayi. Intercepts include grades of up to 1.98% tin (Sn).
• The tin mineralization at Kalayi remains open at depths beyond 250 meters based on the recent drilling. These results significantly expand the known extent of the mineralized system.
• The drilling to date covers only 30% of an identified 2,000-meter-long tin-in-soil geochemical anomaly at Kalayi. Rome Resources is planning to define a maiden inferred mineral resource estimate for the prospect.
• Rome Resources is fully funded to accelerate its exploration program in 2025 following a £4.2 million strategic investment. The company is well-positioned to rapidly advance the Kalayi prospect and its other assets in the DRC.

Rome Resources (AIM:RMR) is a tin explorer focused on the Democratic Republic of Congo (DRC). The company's flagship asset is the Bisie North Project, which includes the highly prospective Kalayi tin prospect located in North Kivu province. Rome is actively advancing Kalayi with the goal of defining a maiden inferred mineral resource estimate.

High-Grade Tin Intercepts Expand Depth Potential

Rome Resources announced further assay results from two diamond core drill holes at Kalayi, confirming the presence of high-grade tin mineralization across multiple sub-parallel ore shoots. Highlights include:

• KBDD015: 3.3m at 1.77% Sn from 96.85m; 5.7m at 1.35% Sn from 147.90m (including 2.85m at 1.98% Sn)
• KBDD016: 9.5m at 0.60% Sn from 126.45m (including 1.7m at 1.61% Sn)

These results validate Rome's geological model and reinforce the potential for tin as drilling moves closer to the interpreted granitic source. Tin mineralization has been confirmed from surface and remains open at depths beyond 250m, with visible cassiterite observed in the deepest hole to date approximately 220m below surface.

Paul Barrett, CEO of Rome Resources, expressed in the news release,

"With tin trading at near-record levels of ~US$34,000/t, our latest results further reinforce Kalayi's economic potential.These new results build on our confidence in the project's growing scale and the continuity of high-grade tin mineralization at depth."

Drilling Confirms Strong Mineralization Continuity

Assay results from KBDD015 and KBDD016 confirm a pinch-and-swell system at Kalayi, with tin mineralization remaining open beyond 250m depth. Two additional shallower holes will complete the current drill program, with assay results from the southernmost hole and the deepest drilled to date expected to show continuity of mineralization on strike and at depth.

The confirmation of tin mineralization 80m below KBDD015 and KBDD016 significantly expands the known mineralized system. This depth extension is expected to materially enhance the resource potential, reinforcing the geological model and supporting further growth as drilling continues.

Kalayi Shares Similarities with World-Class Tin Deposits

The Kalayi tin system continues to show characteristics similar to Alphamin's nearby Mpama South deposit, with potential for deeper high-grade mineralized zones. Ongoing deeper drilling is testing this mineralization zonation model, also seen in world-class tin mines like San Rafael in Peru, where grades have strengthened significantly at depth.

"We now have clear evidence of a strong system extending across multiple zones, improving widths and grades as we drill deeper towards the granite source," noted Barrett. "The combination of high tin grades, growing scale, and Rome's strategic positioning within one of the world's most prospective tin belts places us in a strong position to unlock further shareholder value."

Fully Funded for Accelerated Exploration

Rome remains fully funded for its current program following a £4.2 million strategic investment from Stanvic Mining, enabling an accelerated exploration program in 2025. Drilling continues at both Kalayi and the nearby Mont Agoma copper prospect, with a focus on extending high-grade tin zones and advancing towards a maiden inferred mineral resource estimate at Kalayi.

To date, drilling covers only 30% of the identified 2,000m tin-in-soil anomaly at Kalayi. With over 4,135m drilled, Rome is moving rapidly towards defining this initial resource, which will be a major step in demonstrating the full potential of this emerging tin asset.

As stated in the news release,

"The drill rig at Kalayi was mobilized to Mont Agoma to improve productivity where adverse drilling conditions have resulted in delays. The rig will be returned to Kalayi in due course to complete the remaining holes, ensuring the partial extent of the tin system is captured in the upcoming maiden inferred resource estimate."

Advancing Towards a Maiden Resource

Assay results from the final Kalayi drill holes, KBDD017A and KBDD018, will be sent from Kisangani to Lubumbashi for sample preparation prior to onward transportation to Johannesburg. Results for the bulk of the Kalayi drilling program are expected in the first quarter of 2025, contributing to the proposed maiden inferred mineral resource estimate.

Drill results to date confirm economic-grade tin mineralization at Kalayi and support the potential for open-pit development, with mineralization now confirmed across multiple zones. The deposit remains open for further expansion, with additional results expected to provide greater insight into its full scale.

Exploration Update and Looking Ahead

In addition to ongoing drilling at Kalayi, Rome anticipates assay results shortly from hole MADD018 at its Mont Agoma copper prospect. MADD018 intersected over 100m of visible copper mineralization and will be a critical test for the potential scale of copper associated with the 2,000m copper-in-soil anomaly at Mont Agoma.

Rome's exploration activities remain unaffected by recent unrest in the DRC cities of Goma and Bukavu. The company proactively relocated its logistical base to Kisangani, ensuring full operational capacity and continuity of its drilling programs. The remote location of Rome's projects and limited surrounding infrastructure reduces exposure to regional instability.

For Investors

With its latest high-grade tin drilling results from Kalayi, Rome Resources continues to demonstrate the significant potential of its DRC exploration assets. The confirmation of strong tin mineralization continuity and the expansion of the known mineralized system at depth reinforce the prospect of defining a substantial maiden resource.

Fully funded following a strategic investment, Rome is well-positioned to rapidly advance Kalayi while concurrently evaluating the copper potential at Mont Agoma. As the company moves towards a maiden inferred mineral resource estimate at Kalayi, investors can anticipate a steady flow of news as Rome unlocks the value of its strategic land package within a world-class tin jurisdiction.
