ASX-listed Artemis Resources has appointed Simon Lill as nonexecutive chairperson and Dr Matthew Greentree as an executive director, further bolstering the company’s leadership team as it advances its discovery-focused exploration strategy in the Pilbara, in Australia.

Executive director Jozsef Patarica will transition off the board at the end of March.

The company says these appointments bring together a proven capital markets leader and a highly credentialled gold discovery specialist – significantly enhancing Artemis’ capacity to create shareholder value through disciplined exploration, resource growth and strategic execution.

Lill served on the board of ASX-listed De Grey Mining from 2013 and as chairperson from 2015, overseeing the discovery and rapid advancement of the world-class 11.2-million-ounce Hemi gold deposit in the Pilbara.

During his tenure, he was closely involved in capital raisings exceeding $1-billion, guiding De Grey’s transformation from a sub-$1-million explorer into an ASX 200 company and ultimately through its about $5-billion acquisition by ASX-listed Northern Star Resources.

Artemis says Lill brings more than 30 years’ experience across corporate finance, capital markets and resources leadership, adding that he has extensive experience scaling exploration companies through discovery and into development, and in attracting institutional capital to support growth.

In addition to his previous role at De Grey Mining, Lill currently serves as a director of ASX-listed companies Ballard Mining, Evergreen Lithium and Kairos Minerals.

“Simon’s record in guiding a Pilbara gold discovery from early-stage exploration through to a multibillion-dollar outcome speaks for itself. His experience in corporate growth, capital markets and strategic execution materially strengthens Artemis at a pivotal stage in our development,” says Patarica.

Meanwhile, Artemis describes Greentree as a highly experienced geologist and mining executive with more than 25 years’ global industry experience and a strong track record of discovery and resource growth.

As former MD and CEO of ASX-listed Ausgold, he led the discovery and systematic expansion of the Katanning gold project, growing the mineral resource to 3.04-million ounce of gold and defining a 1.28-million-ounce ore reserve through structurally targeted exploration and drilling.

Artemis points out that, during his tenure, Ausgold’s market capitalisation increased from about $10-million to over $200-million.

The company says Greentree brings deep expertise in structurally controlled gold systems — directly relevant to Artemis’ evolving geological model at Titan East and the broader Carlow system.

Artemis says he will provide strategic geological oversight across the company’s Pilbara gold portfolio, with a focus on refining structural interpretations, prioritising high-impact drill targets and systematically testing extensions and repetitions across multiple centres.

“Matthew has repeatedly demonstrated an ability to convert geological insight into scalable gold systems. His experience in structurally controlled deposits is highly aligned with our strategy at Titan and Carlow, where we are targeting resource growth across multiple centres,” says Patarica.

STRATEGIC CONTEXT

Artemis explains that it is entering a focused and accelerated exploration phase across its Pilbara gold assets.

The company says the addition of Lill and Greentree significantly strengthens both the company’s corporate and technical depth at a time when disciplined capital allocation and geological precision are critical to unlocking scale.

Together, the company says, these appointments align Artemis’ exploration ambition with experienced leadership capable of driving discovery success and translating it into shareholder value.

“The board also thanks Mr Patarica for his contribution to the company and wishes him well in his future endeavours,” the company says.
