Arizona Gold & Silver strengthens exploration leadership with Dr Lex Lambeck appointment as Senior VP of Exploration

Arizona Gold & Silver Inc has announced a major leadership update designed to support the next stage of growth at its flagship exploration asset, the Red Hills project in the US state of Arizona. In a move the company describes as a natural evolution, Dr Lex Lambeck has been appointed Senior Vice President (SVP) of Exploration, while long-time technical leader Greg Hahn transitions to the role of Vice Chair.

This news matters because exploration success isn’t only about drills and geology—it’s also about decision-making, prioritization, and technical leadership. With Red Hills showing signs of scale and long-term potential, Arizona Gold & Silver is positioning its team to manage bigger programs, interpret growing datasets, and pursue high-impact targets with discipline.

What the company announced—and why it matters now

According to comments shared by CEO Mike Stark in a recent interview, the leadership change has been in the works for years. Stark explained that the Red Hills system is extensive and requires experienced technical leadership to unlock its full value—especially as drilling continues and the exploration model becomes more detailed.

The company’s announcement includes two linked moves:

• Dr Lex Lambeck joins as SVP of Exploration, taking a hands-on role in shaping exploration strategy and execution.
• Greg Hahn moves to Vice Chair, a change that keeps his experience close to the business while enabling day-to-day exploration leadership to scale.

In many early-stage and growth-stage mining companies, exploration leadership can make or break outcomes. When a project is small and early, teams can operate with a “tight circle” approach. As a project expands, the company often needs more specialized support—leaders who can run multiple targets, manage teams, and keep a consistent technical standard across programs. That’s the backdrop to this decision.

Who is Dr Lex Lambeck? A closer look at the new SVP of Exploration

While investors often focus on drill results, experienced shareholders know that people are a company’s most valuable “asset” in exploration. Dr Lambeck’s appointment stood out because of his background and the level of confidence expressed by management.

Experience tied to major value creation

CEO Mike Stark highlighted Lambeck’s background and referenced his involvement with MAG Silver, including a high-profile transaction valued at US$2.1 billion, as evidence of the caliber of experience Lambeck brings.

In plain terms: a leader who has seen what “big success” looks like can help a smaller company build the habits and systems needed to grow responsibly. This can include:

• Setting clear technical priorities for drilling and targeting
• Building consistent processes for sampling, logging, and interpreting results
• Communicating exploration logic in a way investors can understand
• Keeping programs focused, rather than chasing every possible idea

A practical, get-it-done style

Stark described Lambeck as someone who can handle multiple projects and is known as a “get-the-job-done” type of technical leader.

That kind of reputation can matter a lot when a project starts moving faster. Exploration has many moving parts—field crews, drill contractors, lab turnaround times, geology interpretation, permitting, and investor updates. A strong SVP can help coordinate these pieces so the company isn’t simply busy, but productive.

Greg Hahn’s transition to Vice Chair: continuity without bottlenecks

Just as important as the new appointment is the way the transition was structured. Instead of stepping away, Greg Hahn is moving to Vice Chair. That matters because it suggests the company wants:

• Continuity—keeping deep project knowledge inside leadership
• Mentorship and support—helping the new SVP integrate quickly
• Better division of labor—so day-to-day exploration can scale without overloading one person

Stark said the company has been preparing for this transition for several years and that Hahn had indicated early on the company would eventually need additional support because Red Hills is a big system.

Investors often worry when leadership changes happen suddenly. In this case, the messaging suggests a planned handoff: measured, deliberate, and aimed at supporting growth rather than reacting to a problem.

Red Hills project: the flagship asset driving the leadership upgrade

At the center of the story is Red Hills. Stark emphasized that Red Hills continues to demonstrate scale and long-term potential, which is a key reason the company is upgrading technical leadership now.

The “3-kilometre strike” detail investors should notice

One of the most striking details shared in the interview was the size of the system at surface. Stark said he, Hahn, and Lambeck walked the entire three-kilometre strike length of the project during a recent site visit.

Even more important: Stark noted that the company has drilled only about half of that strike so far (roughly 1.5 kilometres).

For non-technical readers, here’s a simple way to think about it: if early drilling has confirmed promising mineralization across a long trend, but only part of the trend has been tested, there may still be a lot of room to find additional zones or extend what’s already known.

Why “scale” changes how exploration is managed

Small targets can be explored with a few holes and quick decisions. Large systems—especially those with multiple zones or changing geology—require more structured planning. A project with real scale can lead to:

• More drilling phases (step-outs, infill, deeper tests)
• Multiple target areas being tested in parallel
• More data requiring interpretation (geology, geochemistry, geophysics)
• A stronger need for quality control and consistent methods

That’s one reason companies often add senior technical leadership when a project starts to “graduate” from early-stage curiosity to a more serious, longer-term exploration effort.

Inside the site visit: “He saw the big picture”

Management also shared insight into how Lambeck responded during the site visit. Stark said Lambeck quickly recognized the scale of the opportunity and asked detailed technical questions—something Stark interpreted as a strong signal that Lambeck understood what the company has and what it could become.

Stark described Lambeck’s reaction in plain, enthusiastic language, indicating that Lambeck could see “huge potential” after walking the trend.

While excitement is not the same as proof, it can still be meaningful when it comes from someone with a strong technical background. It suggests that the project’s surface expressions, geology, or early drilling evidence are compelling enough to impress an experienced exploration professional—especially during an on-the-ground inspection.

Drilling continues: what “hands-on” leadership could change

Arizona Gold & Silver said drilling continues at Red Hills, and Stark indicated Lambeck is expected to play a hands-on role as exploration advances.

“Hands-on” matters because it implies Lambeck won’t only be reviewing reports from an office. In active exploration, close involvement can improve:

• Real-time decisions on drill targeting
• Adjustments to hole orientation, depth, and step-out distances
• Prioritization of follow-up holes based on geology observed in the field
• Consistency in how the geological model is built and updated

Over time, these improvements can help a company allocate capital more efficiently—testing the best ideas first, while still keeping optionality for additional targets.

Why hole 159 was mentioned

Stark also noted that recent results and visuals from hole 159 have generated strong enthusiasm internally and among shareholders.

When management highlights a specific drill hole by number, it usually means that hole produced something important—such as encouraging mineralization, better-than-expected geology, or visual indicators that support the broader exploration model. While investors should still wait for full technical details and assay results where applicable, leadership calling out a hole suggests the team believes it supports the project’s bigger story.

7 key takeaways for investors watching Arizona Gold & Silver

1) The company is planning for growth, not just reacting

Stark’s comments frame this transition as something prepared over multiple years—implying a longer-term vision for Red Hills.

2) The Red Hills system appears large at surface

A three-kilometre strike length is meaningful, and only about half has been drilled so far, according to the CEO.

3) Technical leadership is being strengthened at a critical time

As drilling continues, experienced oversight can help convert promising geology into a clear, testable model.

4) Continuity is maintained through Greg Hahn’s Vice Chair role

Keeping Hahn close supports stability, even as daily exploration leadership evolves.

5) Lambeck’s background signals serious exploration intent

Management highlighted Lambeck’s prior experience and deal-related credentials, suggesting confidence in his ability to drive value.

6) Field-level involvement can speed up learning

When a senior technical leader is hands-on, the exploration team can refine targeting faster and reduce “trial-and-error” drilling.

7) Market attention may increase when leadership upgrades align with active drilling

Investors often watch for catalysts. Leadership upgrades combined with ongoing drilling can keep attention focused on upcoming updates.

What happens next: practical milestones to watch

In exploration, the “next step” usually isn’t one single event—it’s a chain of milestones. Based on the company’s comments, here are practical developments investors often track in situations like this:

• Updated exploration strategy: With a new SVP, the company may refine or restate its target priorities.
• Drilling updates: Continued results from Red Hills, including step-outs along the strike length.
• Interpretation improvements: A clearer geological model as data accumulates.
• Communication cadence: More frequent or more detailed technical disclosure as leadership expands.

It’s worth noting that exploration is inherently uncertain. Strong leadership improves odds and efficiency, but it doesn’t guarantee outcomes. The most useful approach for investors is to compare company claims to future technical data over time.
