Northern Graphite Charts Path to Carbon Neutral Project at Bissett Creek

14.02.2022  |  Newsfile

Ottawa, February 14, 2022 - Northern Graphite Corp. (TSXV: NGC) (OTC Pink: NGPHF) (FSE: 0NG) (XSTU: 0NG) (the "Company" or "Northern") is pleased to announce that Minviro Ltd. ("Minviro") has completed an ISO-compliant Life Cycle Assessment ("LCA") on the production of graphite concentrate and lithium-ion battery anode material ("BAM") from the Company's Bissett Creek deposit in order to guide the Company in developing a carbon neutral project. Additionally, Minviro benchmarked the potential carbon footprint of Bissett Creek against the production of Chinese natural and synthetic graphite and their upgrade into battery anode material.

Minviro estimated that by powering the mining fleet with natural gas rather than diesel, and replacing the planned natural gas fired generating plant with hydroelectric power, the Global Warming Potential ("GWP") of the Bissett Creek project could be reduced by more than half, from 2.2 kilograms ("kg") of CO2 eq. per kg of graphite produced to 1.0 kg of CO2 eq. Minviro is undertaking an additional study to quantify the benefits of an electric mining fleet to further reduce the project's carbon footprint.

Minviro estimated that Li-ion battery anode material, also known as coated spherical purified graphite ("CSPG"), manufactured from Bissett Creek mine concentrates under the optimized scenario would have a carbon footprint of 7.3 kg of CO2 eq. per kg of product. In comparison, the carbon footprint of Chinese CSPG produced from natural graphite is estimated at 16.8 kg of CO2 eq. and 17 kg of CO2 eq. if produced from synthetic graphite.

Gregory Bowes, CEO commented that, "the Minviro report indicates that the carbon footprint of the Bissett Creek project can be reduced to levels that create a clear and economic path to carbon neutrality by investing in the creation of credits or purchasing carbon offsets. Very few mining projects can achieve this status." He added that, "the report also highlights the substantially higher carbon footprint of Chinese production, particularly of synthetic graphite."

Minviro's estimate for the carbon footprint of synthetic Chinese CSPG production is based on a plant in Fujian Province where the regional power grid mix has a lower environmental impact than Inner Mongolia where many plants are located and where the grid is largely coal based. Accordingly, synthetic graphite produced in Inner Mongolia has an even higher GWP due to the large volumes of electricity required. ESG concerns as well as shutdowns due to high emissions or power shortages/rationing all create significant supply concerns with respect to Chinese synthetic BAM production.

The EV and battery industries need to be transparent about the environmental impacts of producing both natural and synthetic graphite and manufacturing battery anode material therefrom as graphite is the largest single component of a lithium-ion battery. The evolution from internal combustion engines to EVs will require multiples of current graphite production and the environmental implications need to be well understood. As part of Northern's policy of transparency and full disclosure, and to foster further discussion on this important issue, Minviro's report will be made publicly available here in the coming weeks after the effect of electrifying the mining fleet has been estimated.

Life Cycle Analysis is a cradle-to-gate study meaning that the product life cycle impact is assessed from the point of resource extraction to the end-gate, which in this case, is the production of graphite concentrate and CSPG from the Bissett Creek Project. The study follows the Greenhouse Gas ("GHG") Protocol which identifies three types of GHG emissions. Scope 1 are all direct GHG emissions, Scope 2 are indirect GHG emissions from the consumption of purchased electricity, heat or steam and Scope 3 are embodied emissions, such as the extraction, production and transport of purchased materials and fuels, outsourced activities, waste disposal, etc. The study has been conducted according to the requirements of the ISO-14040:2006 and ISO-14044:2006, including a third-party review from LCA experts to ensure that it is scientifically robust. A number of parameters were calculated using high level assumptions and further testing, data collection and analysis will be conducted.

The goal of Northern's LCA was to identify the major parameters contributing to the global warming impact of producing graphite concentrate, quantify them in different impact categories, and then estimate the impact of various alternatives for reducing the carbon footprint of the Bissett Creek Project. In addition to global warming potential, four other impact categories were evaluated. These categories and the implications of the study results are as follows:

  1. Acidification potential ("AP") relates to the release of SO2 and NO2 into the atmosphere which causes acid rain and ecosystem impairment. The total freshwater and terrestrial AP of the project is calculated to be 1.4E-2 mol H+ eq. per kg of graphite concentrate produced. Approximately 70% relates to the consumption of diesel fuel in mining operations and 20% to natural gas used for power generation. These numbers will be substantially reduced if natural gas or electricity is used to power the mining fleet and hydroelectric power is used to run the processing plant.
  2. Disease incidence ("DI") measures the effect on human health from the release of particulate matter and was calculated to be 3.2E-7 DI per kg of graphite concentrate. Over 80% relates to the consumption of fuel on site, which can be mitigated through the use of natural gas and/or electricity. Dust emissions from vehicles on unpaved roads are minimal due to the low surface silt content and high rainfall.
  3. The total water use for the project is 60.6 kg water eq. per kg of graphite concentrate. The potential for water deprivation to humans or ecosystems is not considered significant as the project is located in an area with a low water scarcity index.
  4. Land use transformation calculates the project's effect on biotic production, erosion potential, groundwater regeneration, infiltration reduction and physicochemical filtration. The tailings dams and waste rock piles will initially create a loss in biotic production and reduce the rate of water infiltration into the soil as well as its physiochemical filtration capacity. These effects will moderate and recover as the areas are revegetated and reclaimed. Tailings dams and waste rock piles contribute to a net reduction in erosion potential but they also reduce the amount of ground water infiltration into aquifers, an effect which is partially offset by increased infiltration in the open pit.

About the Bissett Creek Project
An independent study has rated Bissett Creek the highest margin graphite project in the world including existing producing mines. This is due to its very high percentage of valuable large flake graphite, simple metallurgy and favorable location which provides ready access to equipment, supplies, labor, natural gas and markets.

The Bissett Creek deposit is located in the southern part of Canada between the cities of North Bay and Ottawa and approximately 15 kms from the Trans Canada Highway. A full Feasibility Study has been completed for the construction of a graphite mine producing 20-25,000 tonnes per year of concentrate. However, measured and indicated resources are large enough to support a much higher production rate and the Company is currently re-evaluating its development plans in light of the substantial growth in EV/battery markets. The results of this process are expected to be announced in the coming months.

About Northern Graphite
