HAR Harfang Exploration Inc

Harfang Exploration Inc. (“Harfang” or the “Company”) (TSX-V: HAR) is pleased to announce its field crew began exploration work on its Lemare lithium property in the central part of Eeyou Istchee James Bay, Québec (Figure 1). The property is located to the southeast of the Whabouchi lithium deposit and is accessible by the Route du Nord. With recent lithium discoveries, new advances in already existing resources and the Québec strategy on Critical and Strategic Minerals (“CSM”), this region has taken centre stage for lithium exploration in Canada.

Commented Ian Campbell, President and CEO, “We are pleased to report that the recent restrictions imposed by the Québec government as a result of the regional forest fire situation have been lifted in most of the Eeyou Istchee James Bay region and our field crew has been mobilized to resume the exploration program. This program is a “boots on the ground” approach including both a prospecting and geological evaluation. Access to our properties in the northwest of the region (Lake Menarik, Serpent-Radisson, Ewart, Sakami, Taiga, La Passe and Menarik East) is not yet authorized, but we are hopeful this situation will be resolved in the near future. We wish to acknowledge the continuing efforts to suppress forest fires and express our gratitude to those involved for their hard work under difficult conditions.”

Lithium Exploration Program

Harfang intends to conduct a first-phase surface exploration program (prospecting, mapping, rock sampling) on its assets favourable for the discovery of spodumene bearing pegmatites. This program includes prospecting on the Serpent-Radisson, La Passe, Lemare, Ewart, Sakami, Ross and Conviac claims. The main objective of this program is to find Lithium-Cesium-Tantalum Pegmatite (“LCT Pegmatite”) warranting more advanced exploration, including drilling.

The Company acquired Lemare claims by map designation as a result of geological assessment combined with a statistical processing of more than 13,400 analyses of lake bottom sediments extracted from the Québec government digital database (SIGÉOM) (see news releases dated on January 19 and February 8, 2023). Ewart, Sakami, Conviac and Ross claims were staked following the same evaluation.

The Lemare Property consists of 269 claims located approximately 22 kilometres southeast of the Whabouchi lithium deposit owned by Nemaska Lithium (“Nemaska”). Nemaska recently signed a long-term agreement with the Ford Motor Company for the supply of lithium products, including lithium hydroxide, as North American automakers race to secure supplies of battery materials to meet the electric vehicle output. The Lemare Property contains several strong calculated lake bottom sediment lithium residual anomalies of which four are ≥99.5th percentile of the entire SIGÉOM database (Figure 2). Some of these anomalies form a tight cluster in an area dominated by granite and pegmatite of the Opatica Subprovince.

Once the restrictions are lifted in the northwestern part of Eeyou Istchee James Bay, Harfang will resume its exploration program on its gold and lithium projects in this region.
