Generation Mining Receives Approval to Submit Closure Plan Permit

TORONTO--(BUSINESS WIRE)--September 6, 2023--Generation Mining Limited

(TSX:GENM)(OTCQB: GENMF)(“Gen Mining” or the “Company”) is pleased to announce

that, following consent by the Biigtigong Nishnaabeg (“BN”) Chief and Council of the Closure

Plan for the Marathon Palladium-Copper Project (the “Closure Plan”), the Company has been

issued a letter from the Ministry of Mines (“MINES”) inviting the Company to submit the

Closure Plan. Upon submission of the Closure Plan, supporting documentation, and financial

assurance the Director of Mine Rehabilitation has up to 45 days to approve the plan or return it

for further revisions. This represents another significant milestone in the permitting process for

the Marathon Palladium-Copper Project and reflects the contributions of BN and other

Indigenous groups that were consulted and participated in the overall development of the plan.

The Company expects additional permits and approvals to be received during the fall of 2023.

Jamie Levy, President and Chief Executive Officer of the Company said, “We want to thank

Chief Michano, the Biigtigong Nishnaabeg Band Council and the BN leadership team members

for their support and collaboration with our team on developing the Closure Plan. This is the

conclusion of months of working together to define the social, environmental, and technical

elements of the Closure Plan to achieve the land use envisioned for the property after mining

concludes, including establishing a self-sustaining ecosystem, re-establishing access through the

area for traditional land use and providing future economic development opportunities. The

Closure Plan reflects the significant amount of work undertaken by all parties to produce a plan

that achieves the objectives of all stakeholders.

Forward-Looking Information

This news release contains certain forward-looking information and forward-looking statements,

as defined in applicable securities laws (collectively referred to herein as "forward-looking

statements"). Forward-looking statements reflect current expectations or beliefs regarding future

events or the Company’s future performance. All statements other than statements of historical

fact are forward-looking statements. Often, but not always, forward-looking statements can be

identified by the use of words such as "plans", "expects", "is expected", "budget", "scheduled",

"estimates", "continues", "forecasts", "Projects", "predicts", "intends", "anticipates", "targets"

or "believes", or variations of, or the negatives of, such words and phrases or state that certain

actions, events or results "may", "could", "would", "should", "might" or "will" be taken, occur or

be achieved, including statements related to the anticipated timing for government approvals

and permitting, and the life of mine, mineral production estimates, payback period, and financial

returns from the Marathon Project. All forward-looking statements, including those herein, are

qualified by this cautionary statement.

Although the Company believes that the expectations expressed in such statements are based on

reasonable assumptions, such statements are not guarantees of future performance and actual

results or developments may differ materially from those in the statements. There are certain

factors that could cause actual results to differ materially from those in the forward-looking

information. These include the timing for a construction decision; the progress of development at

the Marathon Project, including progress of project expenditures and contracting processes, the

Company's plans and expectations with respect to liquidity management, continued availability

of capital and financing, the future price of palladium and other commodities, permitting

timelines, exchange rates and currency fluctuations, increases in costs, requirements for

additional capital, and the Company's decisions with respect to capital allocation, and the

impact of COVID-19, inflation, global supply chain disruptions and the war in Ukraine on the

Company, the project schedule for the Marathon Project, key inputs, staffing and contractors,

commodity price volatility, continued availability of capital and financing, uncertainties involved

in interpreting geological data, environmental compliance and changes in environmental

legislation and regulation, the Company’s relationships with First Nations communities,

exploration successes, and general economic, market or business conditions, as well as those

risk factors set out in the Company’s annual information form for the year ended December 31,

decisions with respect to capital allocation. The Company has begun submitting the permit

applications to start preliminary construction activities late in the third quarter of 2023 or as

soon as possible thereafter.

development and production schedule and related costs; the supply and demand for, and the

level and volatility of commodity prices; timing of the receipt of regulatory and governmental

approvals for development Projects and other operations; the accuracy of Mineral Reserve and

Mineral Resource Estimates, production estimates and capital and operating cost estimates; and

general business and economic conditions.
