Lake Victoria Gold Launches Multi-Purpose Drill Program at Imwelo Area C to Support Mine Readiness

Vancouver, British Columbia--(Newsfile Corp. - June 25, 2025) - Lake Victoria Gold Ltd. (TSXV: LVG) (OTCQB: LVGLF) (FSE: E1K) ("LVG" or the "Company") is pleased to announce a 7,750 metre, multi-purpose drilling campaign at the Area C zone of its fully permitted Imwelo Gold Project in northwestern Tanzania. The program is designed to support short-term production readiness, resource conversion, and final pit design optimization, with completion targeted for Q3 2025. This campaign forms a key component of LVG's strategy to initiate a low-capex open-pit operation at Imwelo, with future underground development to be evaluated as part of ongoing high-grade exploration and resource growth.

Strategic Context
The Imwelo Project, located just 12 km from AngloGold Ashanti's Geita Gold Mine, is fully permitted under a 10-year mining license. Backed by a simple development plan and metallurgical recoveries >90%, the Company is targeting first gold within 12 months of commencement of construction.

Area C is the first zone planned for production and has an average grade of 3.7 g/t Au. It also represents one of the highest-grade zones within the Imwelo historical resource envelope. Previous intercepts include:

2m @ 5.06 g/t Au from 15m and; 6.8m @ 14.6 g/t Au from 33.2m (IMWRC-037)
7m @ 3.22 g/t Au from 27m (IMRC-014)
2m @ 7.5 g/t Au from 22m (IMWRC-038)

Reported intercepts are downhole lengths; true widths are unknown. (Source: MEASURED GROUP PTY LTD (MG) Geology and Resource Estimate Report - Imwelo Project, Tanzania, May 2017

Marc Cernovitch, President & CEO of Lake Victoria Gold, commented: "We've designed this program to maximize Imwelo's short-term production readiness while extending the upside case. The drill data will help us finalize early mine scheduling, validate pit design, and potentially unlock high-grade extensions. With Area C now fully defined as our initial production zone, we're making meaningful progress toward becoming Tanzania's next gold producer."

Program Highlights:

• Grade Control Drilling (3,750m RC):
  Designed on a 10x10 metre grid to a vertical depth of 20 metres, this work will define the initial ore/waste interface across the planned Area C open pit. The results will provide critical input for the early-stage mine plan and ore scheduling.

• Strike & Depth Extension Drilling (2,500m RC + 1,500m DD):
  • Strike Extension Drilling (2,500m RC):
    This portion of the program will test extensions along strike to the west of Area C. Faulting identified in previous drilling suggests the mineralized zone may continue beyond the currently defined limits. These holes are designed to assess the continuity and potential expansion of the open pit resource envelope.
  • Depth Extension Drilling (1,500m DD):
    The deepest drilling at Area C to date has only reached approximately 70 metres. This diamond drilling will test the ore zone at depths of 100 and 200 metres, aiming to upgrade existing Inferred resources and evaluate the potential for future underground development targeting high-grade zones at depth.

• Geotechnical & Metallurgical Work:
  Select diamond drill holes will support slope stability assessments for the final pit shell design, while additional core samples will be collected for confirmatory metallurgical test work. These inputs are essential to the final engineering and plant commissioning process.

Seth Dickinson, P. Eng., Chief Operating Officer, added: "We've optimized this program to deliver multiple layers of value-from detailed grade control to geotech validation and deeper exploration. The step-out and depth targets are especially compelling given the structural complexity we've seen to the west. The team is focused on accelerating toward a clean construction start with maximum technical confidence."

The Imwelo Project
The Imwelo Project is gold project located in northern Tanzania immediately to the west of Geita Gold Mine of Anglogold Ashanti. An updated pre-feasibility study ("PFS") was completed in 2021 by Measured Group Pty Ltd of Australia, incorporating mine design, mine planning, scheduling, reserve estimation and costing. The 3.85km² Project is held under a Tanzanian mining licence ML538/2015. The Project is subject to a 2% royalty to a previous owner. The ML is fully permitted for mine construction and production to commence. The Project resource comprises seven mineralized locations that have been drilled and includes 42,000oz Au measured mineral resources at 3.15g/t, 95,700oz Au indicated mineral resources at 1.95g/t and 153,900oz inferred mineral resources at 1.53g/t for a total 291,600oz Au (the "Historical Resource Estimate"). Further information on the Historical Resource Estimate can be found below. The gold occurs as typical quartz vein shear hosted gold deposits suitable for open pit mining. The Project ML provides 'bluesky' potential. Drilling to date has only been down to 80m below surface. A number of areas were not drilled as they were not accessible at the time, and extensions to the known mineralisation remain untested, both along strike and certainly downdip. The Company anticipates it may define a current mineral resource on the Project and, eventually, mineral reserves that will allow expansion of production and extension of the mine life; however, there is no assurance that further exploration will result in the definition of current mineral resources or mineral reserves.

The Historical Resource Estimate is derived from a report entitled "Geology and Resource Estimate Report - Imwelo Project, Tanzania, Lake Victoria Gold Limited" dated May 31, 2017 (the "Report") prepared by Measured Group Pty Ltd. The Historical Resource Estimate presented in the Report was carried out in accordance with the "Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves" (2012 Edition) prepared by the Joint Ore Reserves Committee of the Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Minerals Council of Australia. The Report includes the following

The above noted Historical Resource Estimate dated 31 May 2017 is the last historical mineral resource estimate on the Project and no more recent data is available to the Company. The Historical Resource Estimate is based on a detailed review completed by LVG and Measured Group Pty Ltd. of local conditions. It has incorporated LVG's view of long-term metal prices, foreign exchange and cost assumptions, plus mining and metallurgy performance to select cut-off grades and physical mining parameters. The cut-off grade is based on a gold price of US$1,500 and an 88% metallurgical recovery is assumed in the calculation of the cut-off grade.

A qualified person has not done sufficient work to classify the Historical Resource Estimate as current mineral resources, and the Company is not treating the Historical Resource Estimate as current mineral resources or mineral reserves. The Company believes that the Historical Resource Estimate is relevant to an appraisal of the merits of the Project and forms a reliable basis upon which to develop future exploration programs. The Company will need to conduct further exploration, and there is no guarantee that the results obtained will reflect the historical estimate. In order to verify the Historical Resource Estimate to a current mineral resource estimate, the Company will need to retain a qualified person to verify historical drilling and assaying methods and validate historical results, add any drilling and assaying or other pertinent geological information generated since the last estimation, and complete an updated resource estimate and a new technical report. Significant data compilation, drilling, sampling and data verification may be required by a qualified person before the Historical Resource Estimate can be classified as a current resource. There can be no assurance that any of the historical mineral resources, in whole or in part, will ever become economically viable. In addition, mineral resources are not mineral reserves and do not have demonstrated economic viability. Even if classified as a current mineral resource, there is no certainty as to whether further exploration will result in any inferred mineral resources being upgraded to an indicated or measured mineral resource category.
