YORK HARBOUR METALS PROVIDES PROJECT UPDATES & REPORTS ON CHANNEL SAMPLING AT ITS RECENTLY DISCOVERED BOTTOM BANK RARE EARTH ELEMENTS ZONE

York Harbour Metals Inc. has released positive results from channel sampling at its rare-earth elements Bottom Brook project's newly discovered Bottom Bank REE prospect, Newfoundland and Labrador.

Bottom Bank prospect channel sampling program

The company is pleased to report assay results from its late summer 2023 channel sampling program. The company previously reported (July 31, 2023, press release) high-grade grab sample values from the newly discovered Bottom Bank showings (BB showings), which are situated over 750 metres to the south-southwest of the U3 showings on its Bottom Brook project. A total of 17 channel samples of 0.2 to 1.5 metres in length were collected for a total of 16.9 metres of channel sampling from two separate trenches. Samples were sent to Activation Laboratories Ltd. (Actlabs) for REE-niobium-zirconium-yttrium-tantalum-uranium-thorium-beryllium-phosphate-tin assay inductively coupled plasma optical emission spectroscopy and inductively coupled plasma mass spectrometry package.

Highlights include:

• Samples 116676 to 116678: three m at 1.38 per cent TREO (total rare-earth oxide) (including one m at 2.28 per cent TREO);
• Samples 116679 to 116682: four m at 0.87 per cent TREO;
• Sample 116686: 1.5 m at 1.07 per cent TREO.

York Harbour's chief executive officer and president, Blair Naughty, comments: "We are encouraged by these promising results from our recent channel sampling at the Bottom Bank rare-earth elements prospect. These outcomes not only affirm the potential of our Bottom Brook project but also start a new chapter under my leadership. I recognize the challenges our shareholders have navigated through, and while acknowledging areas for improvement, I remain optimistic as many of you about our future. As the largest shareholder, deeply committed to our collective success, I am focused on steering York Harbour towards sustained growth and value creation. Our commitment is to leverage the strengths of our core projects and enhance shareholder value through meticulous exploration and strategic planning. With additional technical expertise now on board and a renewed understanding of our key projects, we are poised to aggressively pursue development. Thank you for your continued trust and support as we advance our promising projects and build a robust future together."

Bottom Brook rare-earth elements (REE) 2023 sampling program

Diamond drilling at the 100-per-cent-owned Bottom Brook REE project in Newfoundland concluded in early December, 2023. A total of 1,701 metres of drilling was completed over 10 drill hole locations.

The drill program aimed to test the depth and strike extent of the high-grade mineralization identified by the company's spring/summer 2023 trenching, geological mapping and channel sampling program.

The 2024 York Harbour Metals geological team has recently completed a review and re-examination of the Bottom Brook REE diamond drill program data and drill core. The review determined that additional sampling was warranted, resulting in an extra 120 samples being identified and cut from the drill core, in addition to the 447 previously cut core samples. Samples have been sent to Actlabs for REE-niobium-zirconium-yttrium-tantalum-uranium-thorium-beryllium-phosphate-tin assay ICP-OES and ICP-MS package. Assays are pending.

Update from the York Harbour copper/zinc/silver VMS project

York Harbour Metals' copper/zinc/silver volcanogenic massive sulphide (VMS) project technical team has been actively assessing and reinterpreting the York Harbour project. The team has compiled, digitized and remodelled the historical and recent project data collected to date. The team is currently consulting and collaborating with geological and other professionals from other disciplines to assess the project and determine the best way forward to unlock the project's value for the company's shareholders.
