Highland Copper Announces the Successful Completion of the White Pine North Winter Drilling Program

VANCOUVER, April 24, 2024 - Highland Copper Company Inc. (TSXV: HI; OTCQB: HDRSF) ("Highland" or the "Company") is pleased to announce that White Pine Copper LLC., its joint venture with Kinterra Copper USA LLC, has successfully completed its winter drilling program on the White Pine North Project.

The goal of the drilling program was primarily to collect samples for geotechnical and metallurgical testing to support Feasibility Study work. The drilling program was carried out by Timberline Drilling Inc. with geological support from Dahrouge Geological Consulting Ltd. The program ran from mid-January through March and was completed as planned, drilling a total of 6,593 meters in 10 holes focusing on the first ten years of the mine plan area. The program was completed with no reportable safety or environmental incidents.

All holes received geophysical and geotechnical surveys and ore zone material will undergo further metallurgical testing to support engineering studies and permitting requirements. Four of the holes will be revisited this summer for hydrogeological testing. Plans are also underway for a summer drilling program that will focus on infill and resource definition.

In addition to drilling, multiple environmental baseline programs will be conducted throughout the summer to support future permitting efforts.

Barry O'Shea, CEO of Highland Copper, stated, "We are pleased with the success of this drilling campaign and progress the Joint Venture is making on the White Pine North project. Highland's 34% interest in White Pine represents a significant component of asset value in Highland Copper, nicely complementing our fully permitted, 100%-owned Copperwood project. Our partnership with Kinterra Copper USA LLC, has provided White Pine Copper with the capital and technical focus required to continue advancing the project through permitting and study development."
