Snapshot	The Albany Graphite Project hosts an igneous-hosted, fluid-derived graphite deposit and is strategically located near key infrastructure such as roads, rail, power lines, and a natural gas pipeline. On January 8, 2025, Zentek Ltd. announced that its subsidiary, Albany Graphite Corporation achieved five-nines (99.9991%) purity directly from a flotation concentrate sample using a pilot-scale fluidized bed reactor (FBR). The FBR purification process will be further optimized, for Albany graphite, followed by a techno-economic analysis. Achieving five nines purity directly from flotation concentrate marks a major milestone, simplifying the purification process by eliminating intermediate hydrometallurgical steps.

Deposit type

• Breccia pipe / Stockwork
• Hydrothermal

Summary:

Deposit Type
The Albany graphite deposit is a globally 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).

Mineralization
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 pyritepyrrhotite 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 and thirty centimetres. Dyke and graphite fragments range from one centimetre to five centimetres.
