SLR International

What SLR International does

SLR International is a small environmental and permitting consulting firm that operates as lead permitting manager for mining and energy projects, with its primary documented engagement being Eagle Nuclear Energy Corp.'s Aurora Uranium Project on the Oregon-Nevada border. The company's service portfolio comprises Environmental Permitting Services, Environmental Baseline Studies (hydrology, wetlands delineation, flora/fauna assessments), and Archaeological and Cultural Resource Consulting. It coordinates multi-stakeholder field programs including meteorological station installation and cultural/archaeological surveys, occasionally subcontracting specialist firms such as Native-X, Inc. for archaeological work. The legal entity servicing the US project is SLR International Corporation, a US-incorporated entity; the firm's broader footprint is described as North America serving the USA, while firmographics list Whitby, Canada as the headquarters city, founded in 2001 with 1-10 employees.

The business model is project-based environmental consulting — fees are earned through specialized, labor-intensive permitting and field services rather than a software or product offering. Go-to-market is direct-to-enterprise, with the only disclosed customer being Eagle Nuclear Energy Corp., an enterprise uranium mining and nuclear energy company. The firm is led by Rob McCardle (Founder and President). Note: a data conflict exists between firmographics describing the company as a wood-fire-oven manufacturer providing sustainability services and the detailed product/customer data describing an environmental permitting consultancy; the latter characterization is supported by multiple consistent sources and is treated as authoritative.
