Snapshot	February 15, 2023 Zentek Ltd. and 1329307 BC Ltd. are pleased to announce that they have signed a non-binding letter of intent dated February 13, 2023 (the “LOI”), pursuant to which the parties have agreed to negotiate a transaction (the “Transaction”) involving the transfer of Zentek’s Albany Graphite Deposit in northern Ontario to an entity (“SpinCo”) to be listed on a recognized Canadian stock exchange. Zentek believes that transferring the Albany Graphite Deposit asset to a separate entity will enable the Albany Graphite project to move forward with the second year of environmental baseline and hydrogeology studies, with the aim to eventually complete a prefeasibility study.

Deposit type

• Breccia pipe / Stockwork
• Hydrothermal

Summary:

The Albany graphite deposit is a unique example of an epigenetic graphite deposit in which a large volume of highly crystalline, fluid-deposited graphite occurs within an igneous host. The deposit is interpreted as a vent pipe breccia that formed from CO2-rich fluids that evolved due to pressure-related degassing of syenites of the Albany Alkalic Complex and is described in the following subsections (Conly, 2014a; Conly, 2014b; Conly and Moore, 2015).

Preliminary petrography indicates that the graphite-hosting breccias range in composition from diorite to granite, and are generally described as “syenite”. Graphite occurs both in the matrix, as disseminated crystals, clotted to radiating crystal aggregates and veins and along crystal boundaries, and as small veins within the breccia fragments. In addition to graphite, the matrix consists primarily of quartz, alkali feldspar, and plagioclase feldspar with minor phlogopite and amphibole and trace amounts of pyrite-pyrrhotite and magnetite. Alteration is minor, and is most pronounced as a paleo-weathering profile in the upper 20 m of the breccia pipes where bleaching and late, carbonate-filled fractures are common. The stockwork graphitic veins can be several centimetres wide while the veinlets and hairline fractures are millimetre and submillimetre scale. Breccia fragments are dominantly massive to weakly foliated AAC syenite (>95%) with minor to trace chlorite-biotite-rich schist fragments, and mafic to intermediate dyke fragments. Occasional solid graphite fragments and rare altered fragments of unknown origin were also observed. Breccia fragments are angular to subangular to subrounded and range in size from subcentimetre to approximately one metre, most being between three centimetres and 30 cm. Dyke and graphite fragments range from one centimetre to five centimetres.
