Vancouver, British Columbia--(Newsfile Corp. - June 4, 2026) - Graphano Energy Ltd. (TSXV: GEL) (FSE: 97G0) (" Graphano" or the " Company") is pleased to report high-grade graphitic carbon assay results from grab samples collected during the Company's spring exploration program at the newly identified Black Jack graphite showing, located approximately one kilometre northwest of the Company's Black Pearl graphite discovery in Québec.
A total of 28 grab samples collected from the exposed graphite-bearing horizon returned values ranging from 12.0% Cg to 26.5% Cg, with an average grade of 19.8% Cg. Twenty-five of the 28 samples returned grades greater than 15.0% Cg, and 15 samples returned grades of 20.0% Cg or higher.
Dr. Luisa Moreno, Chief Executive Officer of Graphano, commented: " These results confirm the presence of high-grade graphite mineralization at Black Jack and further strengthen our view that this new discovery is an important addition to the broader Black Pearl graphite trend. The consistency of the grab sample results across the exposed horizon is particularly encouraging, with all samples returning strong graphitic carbon values. While grab samples are selective by nature, the results provide a strong basis for the next phase of work, including mapping, stripping, and systematic channel sampling to better define the continuity, width, and scale of the graphite-bearing horizon ."
The samples were collected from an exposed, visually continuous graphite-bearing horizon measuring approximately 100 metres long and up to 15 metres wide. Field observations indicate that the exposed zone represents a single, laterally continuous graphite horizon with homogeneous graphite mineralization. Systematic channel sampling will be required to confirm grade continuity across the exposed width and along strike. The new Black Jack graphite showing is situated along a cluster of airborne conductive anomalies having an indicated strike length of more than 1,100 metres. Further work is required to evaluate this larger scale potential and to determine how it correlates with the nearby Black Pearl graphite discovery.
Highlights
-
The 28 grab samples averaged 19.8% Cg.
-
All 28 grab samples returned grades of 12.0% Cg or higher.
-
25 of 28 samples returned grades greater than 15.0% Cg.
-
15 of 28 samples returned grades of 20.0% Cg or higher.
-
The exposed graphite-bearing horizon measures approximately 100 metres long and up to 15 metres wide.
-
The newly discovered Black Jack graphite mineralization occurs along a cluster of airborne conductive anomalies having an indicated strike length of more than 1.1 kilometres.

Average Grade of all 28 samples is 19.8% Cg
The prospecting samples collected are grab samples which are selective by nature
Sampling and Analytical Method
The samples reported in this news release are grab samples collected from exposed graphite mineralization during the spring exploration program. Grab samples are selective in nature and are not necessarily representative of the average grade of the mineralized zone. All samples were stored and shipped using industry best practices and were delivered to Activation Laboratories (" ACTLABS"), Ancaster, Ontario, for sample preparation and analyses using laboratories' Code 4F-C Graphitic, analyzing C-Graphite (infrared) where the sample is subjected to a multistage furnace treatment to remove all forms of carbon with the exception of graphitic carbon; and C-Total (infrared). ACTLABS is an independent commercial, accredited ISO Certified Laboratory.
