Do Not Vote Yet: Statement from Ljubo Mikulic on Behalf of the Shareholders for Accountability of Lincoln Gold Mining Inc.

Rua Gold Inc. (TSXV: RUA,OTC:NZAUF) (OTCQB: NZAUF) (WKN: A40QYC) ("Rua Gold" or the "Company") is pleased to announce the commencement of an expanded drilling program at its Reefton Project on the South Island of New Zealand, and outlines the strategy for its fully funded 12-month exploration program. 

Robert Eckford, CEO of Rua Gold commented: "We closed Q2 2025 with $14 million in the treasury, placing us in a strong position to execute on our aggressive exploration plan in New Zealand. Over the past month, our Board and Management team have been focused on shaping the Company's strategy to transition us from an explorer to a developer.

With New Zealand's highly supportive permitting regime, our goal is to rapidly build ounces on our balance sheet and enter the "Fast Track Permitting Process" in 2026.

As our gold-antimony resource continues to grow rapidly - and with antimony at the top of every nations' critical minerals lists - the significance of this resource expansion and accelerated permitting is substantial for both Rua Gold and New Zealand"

Reefton Goldfield Exploration Overview

The Reefton Goldfield is an orogenic district that produced 2Moz of gold at grades up to 50g/t up to the early 1900s. Rua Gold has assembled 120,000 hectares within this district that has seen limited drilling in the last 30 years. This goldfield is analogous in age, geology, mineralization style, and geological structure to that of Southern Cross Gold and the Fosterville Gold mine.

Auld Creek: Rua Gold commenced drilling at Auld Creek in December 2024 and has completed ~2,800 metres of drilling. The targeted program aims to add a further 4,000 metres of drilling across four mineralised shoots identified from surface exploration work (Figure 1). Following this, the resource will be refreshed and updated into the 43-101 report.

The Company is targeting an increase of the Auld Creek resource to over 300,000 gold-equivalent ounces by the end of 2025. This target is a global estimate based on current resource surface extension of 350 metres being extended over a 1km on surface at similar depths of 280 metres. Insufficient exploration to define a mineral resource has been completed to date and there is uncertainty if a mineral resource estimate will be delineated, therefore economic decisions should not be made on this target.

Auld Creek is situated between two past producing mines, Globe Progress mine, and the Crushington Group of mines which collectively produced 933,000oz at 14.0g/t Au (Barry 1993).

Cumberland: Initial drilling from Rua Gold confirms the consistency of the near-surface gold mineralization and supports the strong potential of this target. Ongoing drilling is targeting the southern surface extension 100m along strike and at depth. Intensified surface exploration is underway to delineate additional drill targets along the 2.5 km long gold mineralized shear zone.

Additional targets are currently being modelled and surveyed across the Reefton Goldfield, including Caledonia in the north, and Alexander River in the south. Caledonia represents a historical mine recording the highest grade production (9 oz/ton gold) in the Reefton Goldfield. It was abandoned early and represents a shallow development target.

"The first crushing yielded at the rate of 9 oz. per ton, with subsequent crushings averaging about 4 oz. per ton. The ore-shoot had a steep easterly dip, and pitched to the north at about 30°. It had an average length of about 180 ft. and a width of 3 ft." * Henderson 1917.

Alexander River returned historical production of 41Koz @ 26g/t Au, mining ceasing in 1942 due to WWII. Mineralization outcrops over 1.2kms, comprises high-grade quartz reefs and disseminated sulfides; predecessor Siren Gold drilled extensively along the structure, and intersected some exceptionally high-grade zones which remain open at depth (Figure 2 Alexander River long-section schematic).

An Inferred Resource 130koz @ 4.1g/t Au* has potential to develop along strike and at depth, remodeling and further drilling is a priority of the strategic plan.

Glamorgan Exploration Overview

Glamorgan on the North Island is an exciting new epithermal gold target. Rua Gold has completed extensive surface exploration over the past 12 months as a precursor to drill targeting. Four significant gold-arsenic soil anomalies trending north, north-east and north-northwest strike out individually over 4 kms in length. Drill applications have now been submitted and drilling is expected to commence in Q4 2025.

Results from the work to date indicate the classic features of a major epithermal gold-silver system and are identical to the surface features of neighboring OceanaGold Project, Wharekirauponga, which is currently in New Zealand's Fast Track Permitting process with a decision expected in Q4 2025.

Importantly, Rua Gold's Chief Operating Officer, Simon Henderson was a member of the exploration team that led to the discovery of Wharekirauponga and has more the 25 years working in the region.
