NUVAU MINERALS STRENGTHENS ITS BOARD AND TECHNICAL TEAM WITH THE APPOINTMENT OF DAVID PALMER AS A DIRECTOR AND MICHAEL SUTTON AS TECHNICAL ADVISOR TO THE BOARD

Nuvau Minerals Inc. has appointed Dr. David Palmer to its board of directors and Michael Sutton, PGeo, as a technical adviser to the board, effective immediately.

The additions of Dr. Palmer and Mr. Sutton -- two of Canada's most accomplished exploration geologists, each with a record of company-defining mineral discoveries -- significantly deepen the technical and strategic strength of Nuvau's board as the company advances the past-producing Matagami mining district, in Quebec's prolific Abitibi region, toward a production restart while pursuing new base-metal and gold discoveries.

Dr. Palmer is a successful exploration geologist, having led the discovery of the multimillion-ounce Borden gold deposit and the Black Creek chromite deposit before the sale of Probe Mines Ltd. to Goldcorp Inc. Most recently, Dr. Palmer advanced the Novador gold deposit from 700,000 ounces to over 10 million oz before selling Probe Gold Inc. to Fresnillo PLC in an all-cash transaction valued at approximately $780-million.

Mr. Sutton is a founding member of Kirkland Lake Gold and one of two geologists credited with the discovery of the South mine complex at Kirkland Lake -- one of the highest-grade gold systems in Canadian history. Both Mr. Sutton and Dr. Palmer bring more than four decades of exploration experience across the Abitibi greenstone belt and other world-class gold camps. Their combined discovery pedigree aligns directly with Nuvau's district-scale exploration strategy in one of Canada's premier mining camps. They join at a pivotal moment for Nuvau -- perfectly positioned to help shape exploration across the company's Matagami land package of 1,380 square kilometres, shortly after the company completed its earn-in with Glencore in March, 2026, to acquire the district-scale project on a 100-per-cent basis.

"I have had the privilege of working alongside both David and Mike for several years, collaborating closely on the technical review and due diligence of numerous exploration and development opportunities as we evaluated potential acquisitions. Having worked shoulder to shoulder with them, I have seen firsthand how rigorously they assess an opportunity, the depth of their technical judgment and the value they bring to every decision -- and I am confident they will be equally invaluable to Nuvau," said Christina McCarthy, chief executive officer of Nuvau. "David is one of the most successful discovery geologists of his generation, an explorationist who has found and helped build real deposits and delivered real value to shareholders. Mike is an Abitibi exploration authority whose name is synonymous with one of the great high-grade gold discoveries in Canadian history at Kirkland Lake Gold, and understands both exploration and production geology deeply. Their technical depth and discovery instincts will be invaluable as we advance the Matagami district toward a production restart while unlocking new base-metal and gold discoveries."

"Nuvau holds something genuinely rare in the resource sector -- a permitted, past-producing, base metal district with real infrastructure and meaningful untapped discovery potential given the limited exploration that has been done historically," said David Palmer. "Matagami is one of Canada's largest base metals camps, and also a camp which has never been systematically explored for gold. A district like this requires a disciplined and methodical exploration approach, and I am happy to support the technical team on advancing the exploration upside."

"I've spent a large part of my career chasing high-grade discoveries in the Abitibi and the world's great gold camps, and Matagami has all the geological ingredients I look for: a prolific, proven district that remains remarkably underexplored with modern tools," said Michael Sutton. "The chance to help this team target the next generation of base metal and gold discoveries in a camp of this quality is right up my alley and, having built my career in the Abitibi, this is right in my own backyard."

About Dr. David Palmer -- director

Dr. Palmer is an economic geologist and one of Canada's most decorated mineral explorers. As president and chief executive officer of Probe Mines Ltd. from 2003 to 2015, he led his team to two major Canadian discoveries: the multimillion-ounce Borden gold deposit near Chapleau, Ont., and the Black Creek chromite deposit (2009) in Ontario's Ring of Fire. Probe Mines was acquired by Goldcorp Inc. in 2015.

Following that transaction, Dr. Palmer founded and led its successor, Probe Metals Inc. (subsequently renamed Probe Gold Inc.), as president, chief executive officer and director, advancing the multimillion-ounce Novador gold project and assembling one of the larger exploration land packages in Quebec's prolific gold belts. In early 2026, Probe Gold was acquired by Fresnillo PLC for cash consideration of approximately $780-million ($3.65 per share, a 39-per-cent premium). Together, the Goldcorp and Fresnillo transactions underscore Mr. Palmer's repeated ability to identify, define and unlock value-building exploration companies into assets that attract premium acquisitions by senior producers.

In recognition of his discovery record, Dr. Palmer was awarded the Ontario Prospector Award by the Ontario Prospectors Association (2013), named The Northern Miner's Mining Person of the Year (2014), and received the Prospectors & Developers Association of Canada (PDAC) Bill Dennis Award as Prospector of the Year (2015). He holds a BSc in geology from St. Francis Xavier University, and MSc and PhD degrees in economic geology from McGill University, and is a member of the Association of Professional Geoscientists of Ontario. He also serves as chairman and a director of Angus Gold Inc.

About Michael Sutton, PGeo -- technical adviser to the board

Michael W. Sutton, PGeo, is a geologist bringing more than four decades of exploration and mine-production expertise across the Abitibi greenstone belt (Kirkland Lake, Timmins and Malartic) and other world-class gold camps, including the Witwatersrand of South Africa. As chief geologist and assistant manager of Kirkland Lake Gold Inc. from 2001 to 2007, Mr. Sutton is credited with the discovery of the South mine complex -- the high-grade gold system that revitalized the historic Macassa mine and helped establish Kirkland Lake Gold as one of the world's premier high-grade gold producers. For that discovery he was awarded (along side Stew Carmichael) the Ontario Prospectors Association's Prospector of the Year award (2006).

He subsequently served as vice-president of exploration of Vault Minerals Inc., which he guided to a takeover by Queenston Mining Inc., and as a director and head of exploration of Galway Resources Ltd., where he played a significant role in its approximately $340-million (U.S.) acquisition by AUX. From 2014 to 2016, he was senior geologist at Canadian Malartic Corp. (operator of one of Canada's largest gold mines) within the Abitibi region of Quebec. Mr. Sutton serves as a director and chief geologist of Galway Metals Inc. and serves as a director of Rupert Resources Ltd., the company behind the district-scale Ikkari gold discovery in Finland (recently acquired by Agnico). Over his career he has worked for or consulted to leading producers and explorers including Osisko Mining, Kinross Gold, Barrick Gold, Queenston Mining, Lac Minerals and Corona.

Mr. Sutton holds an honours, BSc, in geology from the University of Toronto, is a member of the Association of Professional Geoscientists of Ontario, and has been a member of the Prospectors & Developers Association of Canada since 1982. He is a qualified person as defined under National Instrument 43-101. His deep Abitibi expertise is directly relevant to Nuvau's district-scale exploration of the Matagami camp.

As Nuvau enters its next stage of exploration and development, Ewan Downie has graciously elected to step down from the board to make room for new directors and additional operational and technical talent that will further strengthen the team for this phase of growth. Importantly, Mr. Downie is not stepping away from Nuvau. He will transition to an adviser to the board, remaining closely involved and continuing to lend his experience, relationships, and strategic counsel. One of Nuvau's founding directors, Mr. Downie has been integral to establishing the company and positioning it for its current growth phase, and the board and management are grateful for his continued partnership and guidance in this new role.
