Lake Victoria Gold Announces Additional Drill Results at Imwelo, Extending Mineralization Below and to the East and West of the Current Pit Design

Vancouver, British Columbia--(Newsfile Corp. - December 15, 2025) - Lake Victoria Gold Ltd. (TSXV: LVG) (OTCQB: LVGLF) (FSE: E1K) ("LVG" or the "Company") is pleased to announce additional analytical results from the ongoing 4,000-metre drill program at the fully permitted Imwelo Gold Project in northern Tanzania's Lake Victoria goldfield. Assays from nine new holes further confirm the down-dip continuation of the primary mineralized zone below the current pit design and, importantly, define extensions to both the west and east that had not been previously drill-tested.

The program utilizes RC pre-collars with diamond-core tails to maximize geological, geotechnical, metallurgical, and mineralogical data for final pit-shell optimization, processing design, and evaluation of future underground mining potential.

Highlights

• IMWDR003: 3.56g/t Au over 1.21m from 83.04m including 7.16g/t Au over 0.41m;
• IMWDR011: 8.55g/t Au over 1.30m from 93.34m including; 20.77g/t Au over 0.31m
• IMWDR012: 2.49g/t Au over 2.56m from 79.20m;
• IMWDR013: 9.31g/t Au over 2.45m from 130.00m including 21.65g/t over 0.96m;
• IMWDR017: 11.19g/t Au over 0.90m from 91.8m including 32.84g/t over 0.30m and 2.97g/t Au over 3.01m from 100.52m;

Key Technical Takeaways

Depth extension:

• Drilling continues to confirm mineralization down-dip along the entire pit design, with geological continuity now demonstrated to over 250 m vertical depth, compared to historical resource limits of ~200 m. Current holes average ~120 m depth, more than double historical drilling (~50 m), providing new information below the previous modelled limits.

Lateral expansion (east and west):

• IMWDR012 confirms mineralization beyond the eastern pit margin.
• Drilling west of the interpreted NNE-trending structure has intersected new mineralization west of the fault zone, opening a new area for potential resource growth

Footwall & hanging-wall zones: Additional mineralized intervals outside the primary lode suggest opportunities to add internal ounces within the current design envelope.

Resource conversion potential: Results mirror the grades and widths of holes that support the existing historical resource model, improving confidence in both Inferred-to-Indicated upgrades and the potential for increased Measured resource classification.

Underground optionality: Depth extensions and consistent structural continuity support ongoing evaluation of a potential underground development scenario beneath the planned shallow open pit.
