Riverside Resources' La Union Project Stands at Crucial Inflection Point as Bull Market Tailwinds Build for Polymetallic Payoff

The La Union project sits within a long-established mining district in Sonora, Mexico, built on a geological foundation of carbonate replacement deposits (CRDs). This type of system, where mineralizing fluids replace carbonate rock, is known for hosting high-grade polymetallic mineralization. The project's potential is underscored by its proximity to major developments like South32's Hermosa Project, where similar CRD-style deposits are being advanced with significant capital.

Phase 1 of the exploration program, completed earlier this year, delivered a suite of high-grade discoveries that validate the target model. The standout result came from a 30-meter chip-channel sample at Union Mine, which returned an impressive 20.2 g/t Au and 226 g/t Ag. This oxide zone provides a clear surface expression of the system. More broadly, the drilling program successfully intersected gold in six different targets, confirming the widespread nature of the mineralization. Critically, the program also found zinc-related mineralization at all three key areas-Union Mine, Union Norte, and El Cobre-further supporting the CRD model.

Beyond the drill results, the company has secured the operational foundation for Phase 2. In March, Riverside completed the consolidation of key mineral concessions, finalizing the purchase of three strategic claims. This move secures long-term, fully titled land for the project district with no royalty burden, providing clear title and greater flexibility for follow-up exploration. The combination of these high-grade surface samples, widespread CRD-style drilling hits, and a consolidated land position sets a solid stage for the next phase of drilling.

The Phase 2 Exploration Program: Objectives and Targets

The spring 2026 exploration program is now set to build directly on the Phase 1 findings. The primary objective is to test the continuity and lateral extent of the high-grade CRD system, with a specific focus on the Union Mine trend where the most compelling surface expression was found.

The key target remains the Union Mine area, where a 30-meter chip-channel sample returned 20.2 g/t Au and 226 g/t Ag. This oxide zone provides a clear surface target for follow-up drilling. The program will aim to drill from the upper mine workings or from surface to expand upon this high-grade interval and define its true three-dimensional geometry.

Parallel to this, the company will continue to evaluate the zinc-related mineralization identified at the other two core zones. Drilling in Phase 1 successfully found zinc-related CRD-style mineralization at all three key areas-Union Mine, Union Norte, and El Cobre. These zones represent important extensions of the system and will be prioritized for testing in the upcoming program.

The timing is critical. With the consolidation of key mineral concessions completed in March, the company now has a fully titled, royalty-free land position to execute the spring program. Results from this drilling are expected to define the next steps, whether that means expanding the resource base through further drilling or moving towards a more detailed feasibility study for potential development.

The Macro Backdrop: Sustained Bull Market for Precious Metals

The stage for polymetallic exploration is set against a powerful, multi-year bull market in precious metals. This isn't a fleeting rally but a sustained re-rating driven by fundamental shifts in monetary policy, global uncertainty, and robust demand. For projects like La Union, this macro backdrop provides a critical tailwind, as the value of any discovered resource is directly tied to these elevated price environments.

Gold has led the charge. Prices soared over 55% in 2025, breaching the psychological $4,000 per ounce threshold for the first time in October. The momentum is expected to continue, with forecasts pointing toward prices pushing toward $5,000/oz by the fourth quarter of 2026. This sustained advance is underpinned by a historic combination of factors: a weaker U.S. dollar, reduced demand for the greenback, and explosive central bank buying that averaged 585 tonnes a quarter in 2026. Geopolitical instability and economic uncertainty have further cemented gold's role as a safe-haven asset, with its low correlation to other markets making it a sought-after hedge.

Silver has followed a similar, even more dramatic, trajectory. The metal shattered its decade-long ceiling, posting a remarkable gain of 147% in 2025 to close the year above $72 per ounce. This historic repricing was fueled by a fifth straight year of supply deficits and surging industrial demand from sectors like solar and electronics. The momentum has carried into 2026, with the market expected to remain in deficit for a sixth consecutive year, a structural tightness that supports higher prices. While volatility has returned, with the metal trading above $100 earlier this year, the underlying supply-demand fundamentals remain supportive.

The bottom line is that the current bull market is built on durable trends, not temporary sentiment. The combination of monetary policy shifts, geopolitical friction, and a structural deficit in silver creates a favorable, high-price environment for polymetallic projects. For La Union, this means that high-grade discoveries in gold, silver, and zinc are being evaluated against a backdrop where the value of each metal is being redefined upward. The exploration program is not just seeking ounces; it is assessing potential within a market that is structurally priced for higher returns.

Valuation and Risk: The Trade-Offs in a High-Price Environment

The investment case for La Union is now a function of two powerful, yet volatile, forces: the project's geological promise and the macroeconomic environment. The high-grade discoveries from Phase 1, like the 30-meter chip-channel sample returning 20.2 g/t Au and 226 g/t Ag, provide a tangible foundation. But their ultimate value is entirely contingent on the sustained bull market for precious metals. The project's economics are built on a high-price model, making it inherently sensitive to any reversal in this trend.

The primary risk is a shift in the macro backdrop. Gold and silver prices have been re-rated higher by structural forces-central bank buying, geopolitical uncertainty, and supply deficits. Yet, these are cyclical drivers. A significant change in monetary policy, a resolution of global tensions, or a sudden surge in supply could deflate the premium. For a polymetallic project, this creates a dual vulnerability. While the focus is on gold and silver, the economics also rely on zinc and lead. These base metals have been under pressure, and their prices remain suppressed compared to the precious metals rally. This creates a downside drag on the overall polymetallic economics, even if gold and silver perform as expected.

The trade-off is clear. The high-price environment justifies the exploration risk and the capital required for Phase 2. But it also sets a high bar for success. The project must not only confirm the scale of the high-grade zone but also demonstrate that the polymetallic nature of the system can generate returns that are resilient to base metal weakness. The value of the zinc and lead mineralization, while supportive, is currently a secondary factor in the equation.

The key catalyst for moving the investment thesis forward is the successful execution of the Phase 2 exploration program. The company has secured its land position and has a clear target in the Union Mine trend. The upcoming drill results must confirm the continuity and lateral extent of the high-grade CRD system. This is the single most important test. Positive results would validate the initial promise and provide the data needed to justify a more detailed feasibility study and further investment. Negative or inconclusive results, however, would highlight the project's dependence on a specific, high-grade target within a broader geological system, potentially limiting its upside in a less favorable market. For now, the project's fate is tied to the next set of drill holes and the resilience of the bull market that makes them valuable.
