Pinnacle’s US Focus Raises Questions on Drill Permits and Resource Potential

• Commencement of on-ground exploration at key US projects including Thunder Mountain and Antimony Queen
• Trading initiated on the OTCQB Market to enhance North American investor access
• Strong cash balance of A$2.8 million supports ongoing exploration and corporate activities
• Focus on critical minerals such as antimony alongside gold and silver credits
• Planning resumed for Canadian lithium project amid US portfolio expansion

Strategic Shift to North America

Pinnacle Minerals Ltd has marked a significant milestone in its evolution from asset acquisition to active exploration, focusing on critical minerals in the United States. The December 2025 quarter saw the company mobilise field crews to several promising projects across Idaho and Washington State, signalling a hands-on approach to validating and expanding its mineral portfolio.

Key among these is the Thunder Mountain Gold Project in Idaho, where early-stage evaluations of the historic Lightning Peak Open Pit have confirmed extensive historical workings and mineralisation continuity. This project taps into a rich mining heritage dating back to the late 19th century, offering a compelling foundation for renewed exploration efforts.

Expanding Critical Minerals Footprint

Alongside gold, Pinnacle is targeting antimony; a mineral designated as critical by the US government; through its Yellow Pine and Antimony Queen projects. These sites are strategically located near Perpetua Resources’ Stibnite Gold-Antimony Project, allowing Pinnacle to leverage geological analogues and existing infrastructure. Early reconnaissance and data compilation at these sites have reinforced the potential for significant discoveries, with assay results and geophysical data eagerly awaited.

In Washington State, the Justice Mine Project adds silver and base metals to the company’s diverse portfolio, while in Canada, planning activities have resumed at the Adina East Lithium Project in Québec. This lithium project complements Pinnacle’s US focus, positioning the company within the broader North American critical minerals supply chain.

Corporate Developments and Market Access

Corporate governance remained a priority, with board changes and shareholder meetings successfully conducted during the quarter. Notably, Pinnacle commenced trading on the OTCQB Market under the ticker PIMLF, enhancing its visibility and accessibility to North American investors; a strategic move aligned with its operational focus.

Financially, the company ended the quarter with a robust cash balance of approximately A$2.8 million, underpinning its exploration programs and corporate activities. Expenditure was primarily directed towards project acquisition, early-stage exploration, and technical consulting, reflecting a disciplined capital management approach.

Looking Ahead

Looking forward to the March 2026 quarter, Pinnacle plans to interpret ground exploration data, define priority drill targets, and commence permitting processes. The company also intends to continue strategic reviews of its Australian assets, potentially streamlining its portfolio to sharpen focus on North American opportunities.

Chairman Stephen Ross emphasised the company’s commitment to disciplined capital management while positioning Pinnacle as a key player in the US critical minerals sector, highlighting the importance of these minerals to national supply chains.

Bottom Line?

Pinnacle Minerals’ decisive move into North American critical minerals exploration sets the stage for a pivotal year ahead, with early results and strategic market positioning poised to shape its trajectory.

Questions in the middle?

• When will assay results from the Antimony Queen and Yellow Pine projects be released, and what might they reveal about resource potential?
• How will Pinnacle’s board changes influence the execution of its North American growth strategy?
• What are the prospects and timelines for obtaining drilling permits across the US projects?
