Cheechoo Gold Project: Mineral Resource Estimate Update Underway Based on New Model
Montreal, Quebec--(Newsfile Corp. - May 28, 2025) - Sirios Resources Inc. (TSXV: SOI) (OTCQB: SIREF) ("Sirios") is pleased to announce that an update of the Mineral Resource Estimate (MRE) for its flagship Cheechoo Gold Project in Eeyou Istchee James Bay, Québec, is well underway, with results anticipated as soon as this summer. This update is driven by the adoption of a new game-changing geological and structural model that significantly redefines the deposit's potential.
A Transformative Geological ModelDeveloped in collaboration with leading consultants in resource modeling and applied structural geology, the new model is grounded in a comprehensive analysis of drilling data and geological structures. This work has uncovered previously unrecognized structural controls on gold mineralization, resulting in a redefinition of key mineralized zones and corridors. An interactive 3D viewer of the new model will be made available on Sirios' website upon publication of the updated MRE.
Key Anticipated ImpactsFor the first time, the forthcoming resource estimate is expected to include an underground component—representing a major advancement over the December 2022 estimate. This addition paves the way for expanded resource development through future drilling initiatives.
"Our team's dedication over the past year is coming to fruition as we integrate new insights and data into the upcoming Mineral Resource Estimate," stated Dominique Doucet, President and CEO of Sirios Resources. "We are confident that the new estimate will showcase Cheechoo's substantial resource development potential and reinforce its status as a premier gold project in Québec."
The MRE update is being conducted by PLR Resources Inc., a trusted geological consulting firm founded by Pierre Luc Richard, a recognized expert in mineral resource estimation who has authored and coordinated more than 100 technical reports under National Instrument 43-101.
Livestream Event: May 28To provide further details on developments at the Cheechoo Gold Project and the ongoing resource estimate update, Sirios will host a livestream event later today.

Four-day work week trend blasted by multi-millionaire businessman Kevin O'Leary: ‘Stupidest idea'
A multi-millionaire businessman has ripped into the growing trend of four-day work weeks, calling them the 'stupidest idea' he has ever heard. Shorter working weeks are becoming increasingly popular around the world, with big names like Medibank and Bunnings in Australia among those trialling the change. Kevin O'Leary, best known as one of the investors on Shark Tank, criticised the push for a reduced work week. The outspoken businessman, who is worth an estimated $US400 million, was asked about his thoughts on the push during a recent appearance on Fox News, following the popularity of the four-day week in France. 'That's the stupidest idea I have ever heard,' he said. 'I think we should let the French go to a two-day work week and then kick their ass internationally.' RELATED Four-day week 'wave' coming to Australia: '80 per cent hours for 100 per cent pay' Centrelink cash boost over 400,000 Aussies have weeks left to confirm: 'Get what's yours' Right to disconnect warning as worker sues former employer for $800,000: 'People are nervous' France announced plans to trial four-day working weeks for parents sharing custody of kids last year. The country introduced a 35-hour work week in 2000. Roughly 10,000 workers are already thought to be working four-day weeks. O'Leary, who has also been critical of Australia's right to disconnect laws, was against following in the country's footsteps. 'There is no such thing as a work week anymore anyways in a digital economy post-pandemic,' he said. 'I look at my staff, 40 per cent of them work remotely, all around the world. It's project-based. 'Can you get it done by the 15th of June? Yes, I can. I don't care when you do it, four-day, three-day, five-day.' His comments have divided people online, with some agreeing with him that results rather than work time was the most important thing. 'It's not about days or weeks anymore. It probably never was. It's about productivity in whatever period of time the business decides,' one said. 'Very true. Norms surrounding work are slowly going away between remote work and everything being digital,' another wrote. Others said they supported four-day work weeks and had experienced the benefits themselves. 'I have a four-day work week. I can't express the difference in how much better my work week is given one extra day to decompress,' one said. 'I have been running my company on a four-day work week for a few years now. I can't imagine going back to a five-day week,' another added. The four-day work week has been gaining traction in Australia, with major companies like Medibank and Bunnings testing out the working model. One common approach is the 100:80:100 model, where workers retain 100 per cent of their salary while reducing their hours to 80 per cent and committing to 100 per cent productivity. Medibank announced it would be moving another 250 employees to the trial in October, bringing the total number of participants to 500. Medibank head of people and sustainability Kylie Bishop said it had helped cut down on unnecessary meetings and workloads as staff were committed to getting everything done in the new timeframe. 'We've seen significant and sustained improvements in employee engagement, job satisfaction and the health and wellbeing of participants, while maintaining business performance and customer outcomes,' she said. A Robert Half poll of 1,000 workers and 500 hiring managers last year found 65 per cent of employees wanted a four-day work week with retention of their full salary.

EXCLUSIVE: Sustainable Couture Label ArdAzAei Taps Ulrik Garde Due as CEO
PARIS — Sustainable couture house ArdAzAei is ramping up for its next step of development, with the nomination of Ulrik Garde Due as chief executive officer. 'Ulrik is a seasoned executive with a deep understanding of how to translate creative excellence into market opportunity,' says Johannes Falk, cofounder of ArdAzAei. 'This marks a pivotal evolution for our maison. His leadership will allow us to balance our uncompromising artistic standards with the operational strength required for growth.' More from WWD Balenciaga, Maison Margiela Among Highlights of Provisional Paris Couture Schedule StockX Taps Frequent Nike, LeBron James Collaborator Daniel De Jesus Krueger as Head of Creative EXCLUSIVE: Kizik Names Former Nike Exec Gareth Hosford as Its New CEO A trained gemologist, Iranian Swedish cofounder and creative director Bahareh Ardakani came to couture while taking a technical look at the supply chain combined with an old-world French craftsmanship. She and Falk founded the brand in 2018 in Stockholm and established it in Paris in 2022, with an off-schedule couture show followed by the opening of a showroom and atelier on Rue Saint-Florentin in the 1st arrondissement. From the start, the goal was to build a house complete with couture, ready-to-wear, accessories and high jewelry, all while making it sustainable. For her first Paris show, Ardakani told WWD her ready-to-wear would 'eschew trend-based consumption' — tackling the overconsumption problem of multiple 'must-have' collections a year — and be released in small, in-season drops. ArdAzAei became a guest member of the couture federation starting with the fall 2024 couture season. Its fall 2024 ready-to-wear was its first fully Global Organic Textile Standard (GOTS)-certified collection. For Garde Due, who has served as strategic advisor to ArdAzAei since 2024, the company is 'building something truly exceptional.' 'ArdAzAei is answering a global demand for fashion that carries meaning — crafted with precision, driven by purpose,' the veteran executive declared. 'We're entering a chapter where emotionally intelligent design must meet commercial scale, and I'm excited to bring this vision to the global consumer.' On his roadmap is the brand's expansion into a 'complete wardrobe of ready-to-wear,' slated to be unveiled during October's Paris Fashion Week. Garde Due has extensive experience in the fashion and luxury space, most recently as operational chairman of the board of Cecilie Bahnsen, a position he has held for over nine years. He is also chairman of the board at sustainability reporting and consulting firm Positive Luxury. Previously, the executive served stints as president and CEO of American leather goods brand Mark Cross; president of the living division of Fiskars Corp., which operates Wedgewood, Waterford and Royal Doulton and other home labels; CEO of Temperley London, and president and CEO of Georg Jensen. Earlier in his career, he served as senior vice president of Burberry; global director of marketing and sales at Cerruti, and vice president of North America at Celine.
