Graphano Encouraged by Positive Developments at Black Pearl Graphite Discovery

Vancouver, British Columbia--(Newsfile Corp. - May 28, 2025) - Graphano Energy Ltd. (TSXV: GEL) (FSE: 97G0) ("Graphano" or the "Company") is pleased to announce the completion of the current phase of exploration on the Black Pearl graphite property in Québec, Canada. The program has successfully advanced Black Pearl to drill-ready status and expanded its size potential. Current interpretations indicate a folded trend approximately 1.2 kilometres in length, containing multiple graphite related conductive zones over surface widths of up to 300 metres (Figure 1). The mineralized trend remains open to the north. Graphano's next step will be to conduct additional ground geophysical surveys to further delineate the potential of this significant discovery prior to first-phase drilling.

The Black Pearl discovery was made by Graphano in 2024 through basic prospecting methods. Channel sampling from the initial discovery returned significant grades and thicknesses of graphite mineralization such as 15.1% Cg over 14 metres (m) and 17.9% Cg over 9 m (see Graphano news release of July 16, 2024). The geologic setting of this previously unexplored area is similar to the major graphite deposits of the Lac des Iles region.

The current exploration program carried out by St-Pierre Exploration of Amos, Québec, consisted of line cutting, ground electromagnetic surveys (Max-Min II and VLF-EM), prospecting and mechanical stripping of bedrock. To date, approximately 7 kilometres of line cutting and ground geophysics have been completed. Bedrock stripping during the current program has uncovered high grade graphite zones, ranging from 0.5 to 2.0 m in thickness, over an approximate strike length of 100 metres between L400N and L500N (Figure 1). Channel sampling results are currently pending for this mineralization.

Luisa Moreno, CEO of Graphano, stated: "We are very encouraged by the continued progress at Black Pearl. Advancing the project to drill-ready status and identifying multiple conductive graphite zones confirms the strong potential of this discovery. Our team will now focus on further defining the mineralization through geophysics and drilling. Black Pearl is shaping up to be a valuable asset in our growing portfolio and strengthens our strategy to become a key supplier of high-quality graphite for the electric energy transition and expansion."
