Generation Mining’s Marathon Palladium-Copper Project

Estimated to have One of World’s Lowest Operational

Carbon Intensity

Toronto, Ontario – December 13, 2021 – Generation Mining Limited (TSX: GENM; OTCQB:

GENMF) (“Gen Mining” or the “Company”) is pleased to announce receipt of an independent

report on the operational carbon footprint of the Company’s Marathon palladium-copper project

which, once producing, is estimated to rank as one of the lowest in both Canada and the world

per tonne of copper-equivalent produced.

The report shows that the Marathon project would have the second lowest operating footprint in

Canada, at only 1.5 tonnes of carbon dioxide equivalent (CO2 eq) per tonne of copper equivalent

produced. The comparison was made with 13 producing copper mines across the country. On a

worldwide basis, the Marathon project would be in the bottom 4%. Skarn Associates estimates

that carbon emissions worldwide average 4.65 tonnes of carbon dioxide equivalent (CO2 eq) per

tonne of copper equivalent (Cu eq) produced, with the Marathon project less than one third of

that average. The carbon dioxide equivalent per tonne of copper equivalent produced is as

estimated by Skarn.

“Not only will the Marathon deposit produce minerals that are critical to the energy transition,

but as the operation is currently modeled in the Feasibility Study, these minerals will also be

produced at one of the world’s lowest carbon footprints. Within the dynamics of changing metals

markets and increased consumer awareness, Gen Mining is well positioned to produce a

premium product. We are proudly located in a world class and stable mining jurisdiction with

access to green energy, adding significant value to what is an already robust economic

proposition”. said Jamie Levy, President and CEO

The report was prepared by Skarn Associates Limited, a metals and mining ESG research

company based in the United Kingdom. The report estimates the carbon intensity per tonne of

copper equivalent to be produced by Gen Mining’s Marathon palladium-copper project on

average over all production years, and compares it with other Canadian and worldwide copper

producers for the year 2020.

The curves above represent individual mining operations. The height of the stacked bars representing the CO 2 eq

intensity and the width of the bar representing the relative Cu equivalence production. Cu equivalence calculations

are from Skarn and based on 2020 metal prices. Scope 1 (emissions arising from on-site activities) and Scope 2

(emissions from purchased energy, in this case electrical power required for site operations being generated by grid

power providers) represent direct on site mining and processing CO2 intensity. Other components and contributors

for the estimation of the bar graphs are as described in the chart legends and are reflective of the emissions for the

overall project value chain. The bar graph for Gen Mining is intended to represent the CO 2e intensity of the

operating site as defined in the Feasibility Study (March 3, 2021 and published the NI43-101 Technical Report

dated March 25, 2021.)

As part of the currently underway detailed engineering and procurement processes, the Company

will continue to investigate means to further reduce the carbon footprint of the Project.

About the Company

Gen Mining’s focus is the development of the Marathon Project, a large undeveloped platinum

group metal mineral deposit in Northwestern Ontario. The Company released the results of the

Feasibility Study on March 3, 2021 and published the NI43-101 Technical Report dated March

25, 2021. The Marathon property covers a land package of approximately 22,000 hectares, or

220 square kilometres. Upon closing of the Transaction noted above, Gen Mining will own a

100% interest in the Marathon Project.

The Feasibility Study in respect of the Marathon Project estimated that at US$1725/oz

palladium, and US$3.20/lb copper, Marathon’s Net Present Value (at 6% discount rate) is

approximately C$1.07 billion with a payback of 2.3 years and an Internal Rate of Return of 30%.

Up front capital costs were estimated at C$665 million. The mine would produce an estimated

245,000 palladium equivalent ounces per year over a 13-year mine life at an All-In Sustaining

Cost of US$809 per palladium-equivalent ounce. For more information, please review the

detailed Feasibility Study dated March 25, 2021, filed under the Company’s profile at

SEDAR.com.
