Gratomic Provides Drilling Update on Capim Grosso Graphite Project

TORONTO, June 27, 2022 - Gratomic Inc. ("Gratomic", "GRAT," or the "Company") (TSXV:GRAT)(OTCQX:CBULF)(FSE:CB82) announces that an additional 778.2 m of drilling (for a total of 3,162.8 m to date (the press release dated May 25, 2022 erroneously reported 2,177.7 m for 18 holes but the actual number was 2384.6 m)) of the 5,000-meter drilling campaign on its Capim Grosso graphite project has been completed. 22 diamond drillholes (DD) have been completed to date, with two additional holes in progress. Included in this press release are assay details on holes 14, 15 and 16, outstanding assay results on the remaining completed holes will follow at a later date. The project is located in the Bahia State of Brazil, with the Company holding a 100% controlling interest in the property.

The fourth batch of its drillhole assays from the Capim Grosso Project has been received from SGS Geosol in Brazil which included the following:

• 50 assays, which includes three internal Certified Reference Materials (CRM)

Table 2: Table 2 highlights intervals from holes CGD014, CGD015 and CGD016 on the Capim Grosso Project in Brazil (1 % TGC cut-off grade and 3 % minimum TGC grade used). More detailed information of the assay results from the 2 holes is set out in Table 3 below. Internal QA/QC was performed by Gratomic inserting a Certified Reference Material (CRM) every 20 samples, (OREAS 725) which assayed within 98 % of the expected graphitic carbon value of the CRM. The QP therefore accepts the values of the laboratory assays. The intervals are regarded as true width (or as close as possible to) due to the dip of drillholes being perpendicular on measured dip of geology.

SGS Geosol's graphitic carbon assay methods and equipment include the LECO carbon-sulphur analyzer and high temperature combustion infrared detection. During this procedure, the carbon in the sample is converted to carbon dioxide CO2, which is then measured by infrared (IR) detectors.

Once the drilling is complete and all drillholes are assayed, the Company intends to process the obtained data in order to generate a Maiden Mineral Resource Estimate in accordance with the requirements of National Instrument 43-101 - Standards of Disclosure for Mineral Projects (" NI 43-101 ") for the Capim Grosso asset, which will be combined with pilot metallurgical testing data and other relevant information in order to generate a Feasibility Study (FS) and fast track the project development.

Table 3: Graphitic carbon assays from a further 3 drillholes completed to date on the Capim Grosso Project in Brazil (all drillholes to date have intersected graphite). Drill core was halved, and samples taken according to visual grade estimation in one meter increments. Where visual grade was regarded as continuous, sampling was completed up to a maximum of 2 m increments. Internal QA/QC was performed by Gratomic inserting a Certified Reference Material (CRM) every 20 samples, (OREAS 725) which assayed within 98 % of the expected graphitic carbon value of the CRM. The QP therefore accepts the values of the laboratory assays. The intervals are regarded as true width (or as close as possible to) due to the dip of drillholes being perpendicular on measured dip of geology.

About Gratomic

Gratomic is a multinational company with projects in Namibia, Brazil, and Canada. The Company is focused on becoming a leading global graphite supplier and aims to secure a strong position in the EV (Electric Vehicle) battery supply chain. With the continued development of its flagship Aukam project and further exploration on the Company's Capim Grosso property, Gratomic sets itself apart by seeking out unique top-quality assets around the world. True to its roots, the Company will continue to explore graphite opportunities displaying potential for development. The Company ranked third place in the top 10 preforming mining stocks on the 2022 TSX Venture 50™.

Large quantities of high-quality vein graphite have been shipped for testing to confirm its viability as an anode material. Gratomic is confident that the test results will provide a unique competitive advantage in its desired target markets. The Company will continue to update the public on the status of these tests and will provide results as soon as they become available.

The Company has formed a collaboration agreement with Forge Nano. With its patented ALD (Atomic Layer Deposition) coating, this cooperation with Forge Nano is a key element to support Gratomic's strategies towards the value-added phases of production of graphite for anode applications, namely micronization, spheronization and coating, making Gratomic graphite a preferred choice for use in lithium-ion batteries.
