Abasca Resources Releases Graphite Intersection Assays at its Loki Flake Graphite Zone Including 60 m at 9.09 % Cg.

SASKATOON, SK / ACCESS Newswire / March 3, 2025 / Abasca Resources Inc. ("Abasca" or the "Company") (TSX V:ABA) is pleased to release assay results of the remaining fourteen drillholes at its Loki Flake Graphite Zone (Loki Zone) from its 2024 summer exploration program at its 100%-owned Key Lake South (KLS) Project (Figure 1; For the assay results of the first six drillholes, see the Company's news release dated November 27, 2024). The twenty drillholes totaling 5,499 m were designed at a 100 m x 100 m grid spacing to delineate a 600 m section of the Loki Zone. The Loki Zone remains open along strike and at depth. The 2025 winter drill program is underway to continue the delineation of this emerging 2 km graphite zone (Figure 2). Locations and orientations of drillholes included in this release are listed in Table 1 and their assay results are shown in Table 2.

"The assay data, consistent with on-site drill core logs, confirm our geological interpretation of the Loki Zone. Abasca has provided these data to Understood Mineral Resources Ltd. (UMR), the independent mineral resource consulting firm engaged to complete an initial flake graphite resource estimate for the Loki Zone. Abasca is encouraged by the progress of the KLS project and remains dedicated to creating shareholder value and supporting Saskatchewan's strategy to double the production of critical minerals in the province," stated Dawn Zhou, President and CEO.

Loki Flake Graphite Zone - 2024 Summer Assays

The 2024 summer drill program included 20 holes, totaling 5,499 m, that were drilled at the Loki Zone as part of an initial delineation program. All drillholes intersected graphite mineralization which was encountered at the overburden-basement contact and dips toward the southwest (Figures 3 - 7). The graphite mineralization is hosted in metapelitic rocks of the Wollaston Domain along a northwest-trending fault zone. Pegmatite and local calc-silicate rocks are observed in the hanging wall interlayered with the metapelitic gneiss and also contain local graphite mineralization.

Brian McEwan, Vice-President of Exploration commented "We continue to be excited about this new emerging graphite zone. The results are consistent with our observations, and we are looking forward to extending the zone by further delineation of the Loki Flake Graphite Zone this year."

Results from the remaining 2024 exploration and resampling program are pending, as well as metallurgical testing of samples from KLS-24-052.

Collected samples were sent to SRC Geoanalytical Laboratories in Saskatoon, Saskatchewan, an independent laboratory accredited under ISO/IEC 17025:2017 for preparation and ICP-MS multi-element analysis, boron by fusion as well as graphite content (% Cg) and total sulphur by LECO. Samples were collected in accordance with industry-standard quality assurance / quality control practices and included the insertion of blanks, standard reference materials, and repeats into the sample stream at regular intervals. Samples were also collected for in-field and lab density measurements at regular intervals and through the mineralized zones.
