Sirios Hires Daniel Deschênes to Drive the Cheechoo PEA

Sirios Resources Inc. (TSXV: SOI) has appointed mining engineer Daniel Deschênes, Eng., MBA, as Vice President, Projects, with a mandate to lead execution of the Preliminary Economic Assessment for its Cheechoo gold project in Québec's Eeyou Istchee James Bay region.

Sirios Resources Inc. (TSXV: SOI) has filled a job that tells you where the company thinks it is in its life cycle. The Québec explorer said it has appointed Daniel Deschênes, Eng., MBA, as Vice President, Projects, with a mandate to lead execution of the Preliminary Economic Assessment on the Cheechoo gold project and to oversee the stages that follow it.

Companies do not usually create a projects vice-presidency to keep drilling. They create one when the drilling has produced enough to be modelled, costed and scheduled — and when someone has to be accountable for turning a geological picture into an engineering document. Sirios, which also trades over the counter in the United States as SIREF and in Frankfurt as 377A, is signalling that transition with a single hire.

Why a project engineer, and why now

A Preliminary Economic Assessment is the first formal study that attaches money to a deposit: an early-stage estimate of capital cost, operating cost, mining method, throughput and the price assumptions that decide whether any of it works. It is not a construction decision, and it is not bankable. But it is the document that determines whether a project graduates into pre-feasibility work or stalls in the exploration bucket, and it is the point at which generalist exploration teams typically need someone who has actually built and commissioned things.

That is the gap Deschênes is being brought in to close. According to the company's announcement carried by INN Precious Metals, he is a mining engineer with more than 15 years of experience in the development and operation of both open-pit and underground mines across Québec, Ontario, Africa and South America.

The open-pit and underground point matters more than it might read. Cheechoo's eventual economics depend heavily on which of those two approaches — or which combination — the study settles on, because the choice drives strip ratio, capital intensity, cut-off grade and the size of the mineable resource. Hiring someone fluent in both, rather than a specialist in one, keeps that question genuinely open rather than pre-answered by the team's habits.

A résumé assembled in the right postal code

Deschênes has held senior management positions at Newmont, IAMGOLD, Nemaska Lithium and Windsor Salt, where the company says he led multidisciplinary teams and contributed to engineering, construction and commissioning work. That sequence spans major gold operators, a lithium developer and an industrial minerals producer — a mix that tends to produce managers who are comfortable with schedules and contractors rather than only with orebodies.

The more locally relevant detail is his time in Eeyou Istchee James Bay. He worked at the Éléonore mine and, most recently, served as Infrastructure Director at Nemaska Lithium's Whabouchi mine. Both sit in the same northern Québec region as Cheechoo, and the company explicitly cites his extensive knowledge of it.

For a junior, regional familiarity is not a soft credential. In James Bay the binding constraints on a project are frequently not the rock: they are road and power access, winter logistics, camp and workforce arrangements, permitting sequences, and relationships with the Cree communities whose territory the projects sit on. Someone who has run infrastructure at a nearby operation arrives with a working knowledge of all of it, and with contacts who answer the phone.

His academic background is unusual — degrees in the medical field alongside a Bachelor's degree in Mining and Metallurgical Engineering and an MBA in Strategic Projects. The metallurgical half of the engineering degree and the project-strategy MBA are the parts that map most directly onto running a PEA, which is as much a coordination exercise across consultants as it is a technical one.

Where the shares sit going in

Sirios' US over-the-counter line, SIREF, last traded at 0.14 as of the close on Friday, 4 September 2026, up 0.94% on the day, with a session range of 0.13 to 0.14 and a previous close of 0.14. That is penny-stock territory and thin tape, which is the normal condition for a pre-development explorer and also the reason single announcements can move the quote disproportionately.

The broader market that day gave juniors no particular tailwind. The S&P 500 tracker (SPY) closed at $770.19, down 0.39%; the Dow 30 tracker (DIA) finished at $534.08, down 0.53%; only the Nasdaq 100 tracker (QQQ) advanced, closing at $718.96, up 0.18%. Small resource names generally take their direction from metal prices and their own news flow rather than from index moves, and a management appointment sits firmly in the second category.

What to watch from here

The company has not published a timetable for the PEA in this announcement, and no capital cost, throughput figure or resource number accompanies the hire. Those are the things the study itself will produce, and they are the things worth waiting for. In the meantime, three markers are worth tracking.

Consultant appointments and scope. A PEA is executed largely by outside engineering firms; who is retained, and for which workstreams, will indicate how far along the internal work already is.
The mining-method question. Any disclosure that leans toward open pit versus underground, or a combination, will reshape expectations for capital intensity before a single number is published.
Infrastructure and permitting steps. Given the incoming VP's background, movement on access, power and community agreements would be a natural early area of activity — and in James Bay those items often set the critical path more than the metallurgy does.

The company has not published a timetable for the PEA in this announcement, and no capital cost, throughput figure or resource number accompanies the hire.

Executive hires are among the cheapest signals a junior can send, and they are easy to over-read. But the specific combination here — an engineer with build-and-commission experience, regional depth and an explicit mandate to deliver a study and "oversee the next stages of its development" — is the staffing pattern of a company preparing to be judged on numbers rather than drill intercepts.

Frequently asked questions

Who is Daniel Deschênes?

He is a mining engineer with more than 15 years of experience developing and operating open-pit and underground mines in Québec, Ontario, Africa and South America. He has held senior management roles at Newmont, IAMGOLD, Nemaska Lithium and Windsor Salt, and holds a Bachelor's degree in Mining and Metallurgical Engineering, an MBA in Strategic Projects and degrees in the medical field.

What is a Preliminary Economic Assessment?

A PEA is the first formal economic study of a mineral deposit. It provides early-stage estimates of capital and operating costs, mining method, production rate and commodity price assumptions to test whether a project could be viable. It is not a bankable document, but it determines whether a project advances to pre-feasibility work or stays in exploration.

Where is the Cheechoo project?

Cheechoo is Sirios Resources' gold project in the Eeyou Istchee James Bay region of northern Québec. The company highlighted the new appointee's extensive knowledge of that region, noting he worked at the Éléonore mine and served as Infrastructure Director at Nemaska Lithium's Whabouchi mine, both located in the same part of the province.

How does Sirios Resources trade?

Sirios Resources Inc. is listed on the TSX Venture Exchange under the symbol SOI, quoted over the counter in the United States as SIREF including on the OTCQB, and listed in Frankfurt under 377A. The SIREF line last traded at 0.14, up 0.94% on the day, at the close on 4 September 2026.

Did the company disclose a timeline for the PEA?

No. The announcement stated that Deschênes will lead execution of the Cheechoo PEA and oversee the next stages of development, but it did not include a completion date, capital cost estimate, throughput figure or resource statement. Those details would normally be published with the study itself rather than with an executive appointment.

Why does regional experience matter for a James Bay project?

In northern Québec, the practical constraints on a mining project are often infrastructure rather than geology: road and power access, winter logistics, camp and workforce arrangements, permitting sequences, and relationships with Cree communities. A manager who has already run infrastructure at a nearby operation brings established knowledge of those systems and local working relationships.
