2025 Work Program

Eagle Plains has recently completed over 32-line kilometres of soil geochemical sampling at the Hearne Hill South Project. Samples were collected at ~50m spacing on east/west oriented lines between 200m and 800m apart. The survey was designed to be reconnaissance in scale with the goal of identifying and prioritizing targets for future exploration. 12 rock samples were collected during the program including a grab sample (LWHHR001) from outcrop consisting of very fine-grained granodiorite exhibiting malachite staining on fracture surfaces and mineralized with chalcopyrite, both as fracture fill and disseminations. The sample displays pervasive chlorite alteration with veinlets of epidote and specular hematite. In late January 2025 the company also completed a high-resolution airborne magnetic survey with Precision GeoSurveys Inc. consisting of 286-line kilometres at 100m spacing. Analytical results and interpretation of the 2025 work are pending. All work was designed and executed by TerraLogic Exploration Inc. of Cranbrook, British Columbia.

"We are very pleased to have assembled a significant land position in such an endowed porphyry district in just a couple of years." said Jesse Campbell, Vice President of Exploration. "The Hearne Hill South Project is another example of our corporate goal to increase porphyry copper and gold discovery exposure in our generative portfolio. We are eagerly anticipating results and interpretation from the 2025 work program. I commend the TerraLogic crew on their ability to efficiently execute the work and to identify new mineralization in the first field program."
