GOLDHAVEN ENGAGES NORTHTECH DRILLING FOR INAUGURAL DRILL PROGRAM AT THE MAGNO PROJECT

Goldhaven Resources Corp. has executed a drilling services agreement with Northtech Drilling Ltd. to conduct the company's fully financed inaugural diamond drill program at its 100-per-cent-owned Magno project, located in the prolific Cassiar district of Northern British Columbia.

Highlights:

• Goldhaven engages Northtech Drilling for its inaugural drill program at the Magno project;
• Initial 5,000-to-7,000-metre diamond drill program planned, subject to final permitting;
• Program to test historical tungsten mineralization and high-priority targets generated from the recently completed airborne QMAGT survey;
• Northtech has completed over 600,000 metres of drilling with more than 300 years of combined crew experience;
• Northtech has successfully drilled for major and junior mining companies, including De Beers, Anglo American, BHP and MMG Resources.

The upcoming drill program is expected to commence upon receipt of final exploration permits and will initially comprise approximately 5,000 to 7,000 metres of diamond drilling, with a minimum commitment of 3,000 metres, targeting the company's priority tungsten, silver, zinc, lead, copper and indium mineralization. The agreement contemplates mobilization around Aug. 1, 2026, subject to permitting and mutually agreed scheduling.

The drill program has been designed to verify and expand historical tungsten mineralization at the Kuhn zone while testing additional high-priority targets generated through the recently completed district-scale airborne QMAGT geophysical survey, which covered more than 2,300 line kilometres across the company's expanded Magno project.

Experienced Northern Drilling contractor

Northtech Drilling is a Northern Canadian drilling contractor with more than two decades of operational experience and has completed over 600,000 metres of diamond drilling across Canada. The company brings over 300 years of combined crew experience and has successfully completed exploration programs for numerous major and junior mining companies, including De Beers, Anglo American, BHP, Kennady Diamonds, Yukon Zinc, NorZinc, MMG Resources, North Arrow Minerals, Blue Star Gold and others.

Rob Birmingham, president and chief executive officer of Goldhaven, commented:

"Securing Northtech is another important milestone as we continue preparing for our inaugural drill campaign at Magno. Their extensive experience operating in Northern Canada, combined with a proven track record on technically challenging exploration projects, makes them an excellent partner as we begin testing what we believe is one of the most compelling critical minerals exploration opportunities in the Cassiar district.

"With financing complete, our district-scale airborne survey now finished and a drilling contractor in place, we are entering the final stages of preparation ahead of drilling. We look forward to mobilizing as soon as permits are received."

2026 drill program

The inaugural drill campaign is expected to focus on several priority target areas across the Magno project, including:

• Verification and expansion of the historical Kuhn tungsten skarn mineralization;
• Testing interpreted extensions of known tungsten-bearing skarn horizons;
• Initial drill testing of targets generated from the recently completed airborne QMAGT magnetic survey;
• Evaluation of additional silver-lead-zinc CRD (carbonate replacement deposit) and intrusion-related targets identified across the district-scale land package.

The company believes the combination of historical drilling, high-grade surface sampling, extensive airborne geophysics and geological modelling provides a strong foundation for the upcoming exploration program.
