Star Metro - Tocvan Announces Multiple Silver Zones In Debut Drill Results From The Gran Pilar Project North Block

Results include multiple wide Ag‑bearing intervals, strong quartz-vein and alteration intensity, and clear structural‑lithological controls that together establish a compelling framework for expansion drilling.

Highlights

• Three of five drillholes intersected greater than 1 oz/t Ag, across two targets 1.8 km apart. Multiple additional intervals delivering 3-5 m composites grading 15-20+ g/t Ag, with coincident Au, Zn, Pb, and Sb enrichments. Includes 1.5 meters of 54.3 g/t Ag (JES-25-125) and 1.5 meters of 37.2 g/t Ag, 1.2% Pb and 0.4% Zn (JES-25-127).

• Second drill rig secured with CANMEX Drilling for February to accelerate follow-up drilling on priority targets.

Why This Matters

• Demonstrates a new mineralized system separate from the South Block/Main Zone.

• Silver mineralization correlates with strong sericite-chlorite-carbonate alteration and silicified dikes acting as fluid pathways.

• Geochemistry (Ag-Zn-Pb-Sb-As) and alteration place the discovery in the core of a low‑sulfidation epithermal system, supporting significant depth and strike potential (see Figure 3.).

Next Steps for North Block

• Step‑out drilling around the JES‑25‑124 dike corridor to test continuity along strike and down‑dip.

• Systematic follow‑up on JES‑25‑126's shallow polymetallic intervals.

• Expanded alteration mapping to refine vectors using AI-CCPI zonation.

• Correlation to recently completed drone magnetic survey.

• 3D geologic modeling integrating structure, lithology, and multi‑element geochemistry.

"These first holes at the North Block immediately confirm a new silver discovery over five kilometers from our Main Zone. The combination of high-grade silver, strong polymetallic support, and textbook hydrothermal alteration signals we are into a significant mineralized system. Particularly exciting is the discovery of a high-grade silver zone hosted within a silicified dike, structures like this are known to focus mineralizing fluids in productive epithermal environments. With multiple stacked intervals across several holes, we are rapidly building confidence that Gran Pilar has the grades, continuity, and scale potential to make this an exciting new growth area for Tocvan. With a second drill rig arriving in February, we are positioned to rapidly build on these results" - Brodie Sutherland, CEO

Technical Discussion

Strong Silver Grades with Polymetallic Support

The maiden program identified 25 Ag‑rich composite intervals above the 10 g/t Ag threshold. The strongest interval, 4.58 m at 35.7 g/t Ag, including 1.5 meters of 91.6 g/t Ag, also carries supportive Cu, Pb, Zn, Sb, and As values. The accompanying geologic indicators reinforce the grade significance.

The shallow interval in JES‑25‑126 (79.3-82.35 m), yielding 3.1 meters of 28 g/t Ag (85.5 Ag‑ppm·m), is enriched in Sb and Zn and occurs within moderately to strongly silicified andesite, consistent with the zoned alteration halos expected around epithermal feeder zones.

Alteration Index Vectoring

Alteration mapping using Ishikawa Alteration Index (AI) and Chlorite-Carbonate-Pyrite Index (CCPI) highlights zones of intense sericite-chlorite-carbonate alteration. Several of the top composite intervals plot in the high‑AI, high‑CCPI quadrant, indicative of proximity to mineralized fluid pathways. These zones will guide next‑phase drilling.

Lithological & Structural Controls

The integration of lithology logs shows a strong correlation between grade and silicified dikes and andesitic hosts. No significant Ag intervals were found directly within fault gouge zones, but faults may act as feeder structures for the mineralized dikes and veins.

A particularly important control is the silicified andesitic dike in JES‑25‑124, which hosts the highest‑ranked target and represents an excellent structural corridor for follow‑up drilling.

Exploration Model Placement and Potential

The Gran Pilar North Block drilling intersects the central portion of a low‑sulfidation epithermal system, positioned within the quartz-sericite-sulfide stockwork and feeder‑vein zone. Alteration (AI-CCPI) and lithology indicate strong silicification and sericite-illite assemblages, while metal associations (Ag-Zn-Pb-Sb-As ± Cu) correspond to the mid‑level Ag‑rich epithermal environment shown in the model-between the shallow argillic cap and deeper base‑metal zones.

Quality Assurance / Quality Control

Rock and Drill samples were shipped for sample preparation to ALS Limited in Hermosillo, Sonora, Mexico and for analysis at the ALS laboratory in North Vancouver. The ALS Hermosillo and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. Gold was analyzed using 50-gram nominal weight fire assay with atomic absorption spectroscopy finish. Over limits for gold (>10 g/t), were analyzed using fire assay with a gravimetric finish. Silver and other elements were analyzed using a four-acid digestion with an ICP finish. Over limit analyses for silver (>100 g/t) were re-assayed using an ore-grade four-acid digestion with ICP-AES finish. Control samples comprising certified reference samples and blank samples were systematically inserted into the sample stream and analyzed as part of the Company's robust quality assurance / quality control protocol.

Over limit analyses for silver (>100 g/t) were re-assayed using an ore-grade four-acid digestion with ICP-AES finish. Control samples comprising blank samples and certified reference materials were systematically inserted into the sample stream and analyzed as part of the Company's robust quality assurance / quality control protocol.

Notes & limitations

• Alteration indices (Ishikawa AI and CCPI) follow the Alteration Box Plot definitions

(AI =100·(K₂O+MgO)/(Na₂O+CaO), CCPI = 100·(FeO+MgO)/(Na₂O+K₂O)); they're standard tools for mapping sericite-chlorite-carbonate-pyrite development near epithermal systems
