HIGHLAND COPPER PROVIDES UPDATE ON MICHIGAN STATE GRANT AND OTHER CATALYTS AT THE

COPPERWOOD PROJECT

Vancouver, Canada, July 2, 2025 – Highland Copper Company Inc. (TSXV: HI; OTCQB: HDRSF) (“Highland”

or the “Company”) is pleased to provide an update on its 100% -owned Copperwood Project

(“Copperwood”), which continues to make significant progress toward a near-term construction decision.

Michigan State Grant: As previously announced, the Copperwood project is under consideration for a $50

million grant from the Michigan Economic Development Corporation (“MEDC”). The proposed grant is

awaiting final approval from the Senate Appropriations Committee. Highland con tinues to discuss the

merits of the regional infrastructure grant with the Committee.

In parallel, Wakefield Township, where the Copperwood project resides, has taken the proactive step of

directly requesting a $50 million infrastructure grant from the Michigan legislature . This is a strong

demonstration of local support for the Copperwood Project. This request creates a separate path for the

potential approval of the regional infrastructure funding. If one path is successful, the other will no longer be

required. For clarity, the total grant request will not exceed $50 million.

The proposed grant has the potential to unlock important economic development in Gogebic County, aimed

at upgrading local roads, power, and telecommunications , infrastructure that will also support the

development of the Copperwood project . The grant is in the form of a state budget request for Wakefield

township, sponsored by Rep resentative Greg Markkanen, and is viewed by the local community as a

generational opportunity to attract much-needed jobs and opportunities in the Western Upper Peninsula.

"The people of Wakefield Township and the Western Upper Peninsula are squarely behind the Copperwood

Project. It will create jobs and opportunities while balancing the environment," stated Wakefield Township

Supervisor Mandy Lake. This direct appeal from Wakefield township highlights the project's broad support,

which also extends to state and federal leaders . This includes federal Congressman Jack Bergman and all

key Upper Peninsula state legislators who emphasize Copperwood's critical role in domestic cop per

production, national security, and creating sustainable American jobs while upholding stringent

environmental safeguards.

Detailed Engineering: Following the announcement that Highland awarded the Front-End Engineering and

Design (“FEED”) contracts for mine engineering and process plant engineering to DRA Global, the company

has now finalized the resourcing for its other engineering workstreams. Specifically, Highland awarded the

FEED contract for overall site water management to Foth Infrastructure and Environment LLC ( “Foth”) and

the FEED contract for the Tailings Disposal Facility ( “TDF”) to Tetra Tech. Each engineering team has

completed a comprehensive review of all historical project data and is progressing toward finalizing the

engineering design criteria by Q3 2025 . Concurrently, several opportunities to de -risk and optimize the

project are being evaluated through trade -off studies. Further updates will be provide d as the trade-offs

studies are concluded.

Highland plans to transition into Phase 2 of its engineering program during Q3 2025. The objectives for Phase

2 include advancing mine engineering, process plant engineering, and water management engineering to

approximately 35% completion, while achieving an 85% engineering completion level for the TDF. This

critical phase is scheduled for completion by Q1 2026, positioning the Copperwood Project for project

financing and a subsequent construction decision.

Metallurgical Test Work: In May 2025, Highland announced the successful completion of its metallurgical

drill program, with 400 kilograms of core samples sent to Base Metallurgical Laboratories Ltd. As the

samples were collected from the same locations as the 2018 SGS test work ca mpaign, the initial objective

was to produce rougher kinetic results within the same confidence interval as the 2018 results, which has

been successfully achieved. This outcome provided confidence to proceed with the metallurgical and

reagent optimization phase.

Preliminary optimization results suggest potential for a mill -float-mill-float (MF2) circuit configuration

combined with a simplified reagent scheme. The next steps include evaluating ultrafine flotation technology

for both rougher and cleaner applications , followed by lock -cycle variability testing on the finalized circuit

configuration. The key purpose of evaluating ultrafine flotation is to determine the potential to enhance the

grade-recovery curve, a significant driver of project economics. This technology is also capable of delivering

cost savings by reducing the physical footprint of the processing plant and further minimizing the project’s

environmental impact. Highland remains on track to announce the final metallurgical test results in Q3

2025.

2025 Site Work: The primary objective of Highland’s 2025 construction season is to fulfill its remaining

obligations related to mitigation activities under the Wetlands and Streams Permit. The Company is pleased

to announce the substantial completion of on -site mitigatio n construction, marked by the successful

planting of nearly 20,000 trees in the newly constructed wetland and streams areas. The work has been

subject to numerous visits from Michigan’s environmental authorities. The mitigation project will now

transition into the monitoring phase.

Additionally, the off-site stream mitigation project, undertaken in partnership with a local road commission,

remains on track to replace several undersized culverts with a 50-foot-span bridge. This initiative is designed

to enhance fish habitat across man y miles upstream and is progressing within both budget and schedule

parameters. Similar to the wetland project, construction of this bridge meets our mitigation obligations to

offset site impacts. These efforts reinforce Highland’s operational presence, demonstrate its commitment

to environmental stewardship, and strengthen relationships with local authorities and stakeholders. The

2025 work program represents the final site activities required before a construction decision.

Barry O’Shea, President and CEO of Highland Copper, commented: "Highland is focused on key work

programs that should enable a construction decision for Copperwood in 2026. This includes early site work

to prepare for construction, progress on detailed engineering and metallurgical optimization, and continued

advancement on state and federal funding opportunities. I am pleased that we are making significant

progress in all of these areas, providing increased visibility to a construction decision. We are particularly

pleased with the support demonstrated by the Wakefield township regarding the state grant , a powerful

testament to this project's transformational potential for the region . At the same time, we are advancing

discussions regarding potential financial support at the federal level”.
