Sunstone Environmental Solutions
Finding the Path and Guiding the Way Forward in Mining

No two mining projects are alike. Each comes with its own terrain, timeline, investment pressures, and regulatory landscape. In this complex environment, what companies need most isn’t just technical guidance—they need a strategic partner who can adapt to shifting priorities, understand the full scope of a project, and help shape a realistic path forward.

That’s exactly what Sunstone Environmental Solutions delivers.

Based in the Western U.S., Sunstone is a full-service environmental consulting firm specializing in metals mining, permitting, and land management. But what sets the company apart isn’t just its range of services—it’s the way the team approaches each client’s situation as uniquely their own.

“We don’t use a cookie-cutter approach. We sit down with our clients, understand what really matters to them at this point in their project—whether it’s time, funding, or compliance—and craft a solution that actually fits,” says Joseph Martini, president of Sunstone Environmental Solutions.

This flexibility is backed by decades of dual-sided experience. Both Martini and Vice President Eric Dougherty have worked on both sides of the industry—as in-house project leads at mining companies and as consultants navigating agency requirements. That perspective allows them to anticipate risks, manage stakeholder expectations, and move projects forward with precision and integrity.

“We’ve worked the sites, sat at the investor table, and we understand what these projects really require—not just from a regulatory standpoint, but from an operational and financial one,” says Dougherty.

A Company Built for Complexity

Sunstone supports clients across the full life cycle of mining projects—from early-phase exploration and permitting to long-term compliance, land ownership, and claims management.

Its client base spans operators working with precious and industrial metals, and increasingly, those engaged in critical mineral development. With mine exploration on the rise, Sunstone has become a go-to partner for miners balancing urgency with regulatory complexity. Over the years, it has built strong working relationships with regulatory agencies and stakeholders across the Western U.S., enabling the company to navigate permitting processes more effectively and advocate for balanced, practical solutions.

Sunstone understands that what clients often need isn’t always what they initially ask for. Some seek speed, trying to get a greenfield project into operation before funding windows close. Others juggle competing priorities across multiple sites. Many face pressure from investors to produce timelines that don’t always reflect regulatory realities.

To address these challenges, the company establishes clear, honest communication with clients, ensuring that solutions are realistic, compliant, and on track.

Another key strength is its adaptability. When priorities shift or directions change, Sunstone adjusts accordingly—helping clients pause one project without losing ground while accelerating another. It thrives in a fluid environment where collaboration is constant and strategy evolves alongside the client’s needs.

This approach has helped clients overcome serious roadblocks and stay on course, even in high-pressure situations. In one recent case, a mining operator faced uncertainty after failing to meet certain regulatory requirements. With agency enforcement looming, the project risked stalling entirely.

Sunstone stepped in—not with prepackaged answers, but with a clear, strategic process. The team reopened communication between the client and the agency, clarified expectations, and helped both sides find common ground. Within weeks, the project resumed—compliant, realigned, and back on schedule. Situations like this demonstrate why clients trust Sunstone not just as a consultant but as a long-term partner in progress.

Looking Ahead, Staying Grounded

The company is growing with purpose. It’s expanding its work in lithium and critical mineral exploration while adding more engineering capabilities, including civil and mining disciplines. It also recently hired a land and claims management specialist to deepen its support for clients navigating property ownership and permitting requirements.

Sunstone recognizes that mining plays a vital role in the nation’s economic future. It approaches its work with responsibility, technical depth, and long-term vision. By aligning regulatory understanding with industry goals, Sunstone Environmental Solutions helps move essential projects forward—efficiently, strategically, and with integrity.
