Yono Gold Project: A High-Potential Gold Exploration Opportunity in Guyana

Overview of a Tier 1 Gold District Asset

The Yono Gold Project is located in Guyana’s Cuyuni-Mazaruni Mining District, a region recognized for its significant gold potential. Yono is strategically positioned adjacent to over 8.9 million ounces of indicated and inferred gold resources from G2 Goldfields’ Oko Main Zone (OMZ) and Ghanie deposits, and G Mining Ventures’ Oko West deposit. Tajiri closed on the previously announced acquisition of a 65% interest in the project in September 2025.

Project Highlights

Exploration Targets

• Ridgeline Structure: The largest anomaly, extending up to 4 km in strike (1.5 km within Yono), with gold values exceeding 100 ppb Au. It aligns with OMZ’s high-grade resources and a major magnetic contact, suggesting a significant mineralizing shear zone, further supported by artisanal workings to the south.

• Ghanie West Extension: 780m strike, 50–100ppb Au, extending from the Ghanie West vein zone working, immediately adjacent to the Project – trending SW-NE through the south of the Project and associated with a distinct magnetic contact.
  
• The Splay: 580m strike with peak auger values of 5.1 g/t and 1.6 g/t Au.  The zone parallels the gross orientation of the magnetic high whose contacts host Ghanie West and Ridgeline. The Splay follows co-incident magnetic (weak internal) and strong topographic lineaments.
  
• ‘Tweener: 1,000m strike, 30–375ppb Au, apparent source of significant alluvial & colluvial gold workings, located within a region of low magnetic susceptibility, located between Ridgeline and High Road.
  
• High Road (Down-dip extensions): 950m strike, located on GMin’s tenure, immediately west of Yono, comprised of anomalous soil and shallow scout RC samples, likely dipping into the property.[i]
   

Investment Case

Yono’s proximity to proven gold resources, combined with compelling geophysical and geochemical data, positions it as a high-value exploration asset in a mining-friendly jurisdiction.

• Alignment with Neighboring Deposits: It aligns with the center line of the Oko Main Zone (OMZ) open pit and high-grade resource, located about 700 meters to the north, as well as the average measured S2 foliation at OMZ. This positioning places the Ridgeline anomaly within the same gold-enriched domain as the adjacent gold resources.
• Geophysical Features: Exploration targets coincide with a major magnetic contact traversing central Yono, identified from prior airborne magnetic surveys. This contact is interpreted as a potential shear zone or structural corridor conducive to gold mineralization.
• Extension and Artisanal Evidence: Ridgeline extends southward beyond Yono’s boundaries to a substantial artisanal gold working, highlighting its continuity and historical mining interest in the area.
• Yono’s Unique Location Provides a Valuation Floor or Put Option due to:
• Ounce Sterilization –  Yono is close enough that it will be needed for waste stripping at some point.
• OKWD-GHANIE SUPER PIT .  Potentially another OKWD Block 4 Main Shoot which pulls OKWD pit down to 640m @ USD1950/oz.  Yono may  prevent OP mining of a lot of ounces in this new discovery zone.
• New splay zones strike directly into or along Yono
• Will make Mine planning easier :
• Surface Water Control;
• In the blast radius of the Open pits;
• Allow waste stripping scheduling;
• Potential hanging wall lodes will improve economics of Ops on neighbours resources;
• Additional near mine infrastructure;
• Only ~10% of current G2 & GMIN resources are oxides any new finds on Yono will help mill blending.
• Yono is a medium scale Mining Permit-  We can start mining (gravity recovery) without further approvals.

The highest-grade section of OKWD could fit between Tajiri’s current auger line spacing along the Ridgeline Anomaly. The potential to discover a similar high-grade shoot within the Yono Project is excellent.

Exploration Strategy and Next Steps

The next phase of exploration is planned to include follow-up trenching and deeper auger sampling below the duricrust to refine targets, followed by drilling to test priority zones like Ridgeline and High Road. Ongoing sampling results are expected to further guide planning of phase II.
