Rua Gold INC. (TSX: RUA,OTC:NZAUF) (NZX: RGI) (OTCQX: NZAUF) ("Rua Gold" or the "Company") is pleased to announce the filing on SEDAR+ of independent Technical Reports for its Reefton Project ("Reefton Technical Report") on the South Island and Glamorgan Project ("Glamorgan Technical Report") on the North Island of New Zealand.
Highlights:
- The updated resource profile demonstrates increases in all four MRE prospects.
- The updated Auld Creek MRE includes an Indicated Mineral Resource of 0.3Mt @ 3.18g/t Au and 12% Sb, containing 31koz of gold and 3kt antimony (54koz AuEq2). Also, an Inferred Resource of 1.25Mt @ 2.0g/t Au and 0.8% Sb, containing 79koz of Au and 10kt of Sb (148koz AuEq2).
- 19,000 meters of drilling in the next 7 months is focused on expanding the MRE northwards and at depth. · The Company is currently undertaking planning, environmental and social studies to support a Fast-track Referral application in the first quarter of 2026.
- Rua Gold will be undertaking a Preliminary Economic Assessment (PEA) study during the first half of 2026 precursor to a Pre-Feasibility Study (PFS) in the second half of the year.
The Mineral Resource Estimate ("MRE") for the Reefton Project included in the Reefton Technical Report provides a strong starter resource to initiate the mine permitting process in New Zealand via the Fast-track1 process on its Auld Creek target while providing the foundation for technical and economic studies. An aggressive 19,000-meter drill program is underway with 4 drill rigs in operation from 2 March 2026.
The Reports, titled "Technical Report on the Reefton Project, New Zealand, Report for NI 43 - 101 on the Reefton Project, New Zealand" and "Technical Report on the Glamorgan Project, Report for NI-43-101 on the Glamorgan Project, New Zealand" respectively, with effective dates of February 27, 2026, are available on SEDAR+ under the Company's profile at www.sedarplus.ca and on the Company's website at www.ruagold.com. Each report was prepared by RSC Consulting Ltd. ("RSC") and authored by Abraham Whaanga, BSc, MAusIMM (CP) of RSC, a "qualified person" as defined in National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). RSC and Mr. Whaanga are independent of the Company, as determined in accordance with NI 43-101.
The Company's COO Simon Henderson said, "Since November 2024 drilling has prioritised the Auld Creek gold-antimony project to advance one project toward a mine development phase. With gold-antimony mineralisation outcropping at surface, and continuing unconstrained at depth and along strike northward, Auld Creek presents a compelling opportunity to establish a central processing hub for high grade gold and gold -antimony projects within a 30 km range.
"The 19,000m drill program, and additional regional projects at Alexander, Big River, Golden Treasure and Fiery Cross to be tested in the 2026 year provide both resources and excitement in the exploration team to revitalise the Reefton gold district."

Auld Creek 2026 Drill Program
Following the well supported financing in January 2026, an expanded drill program was launched at Auld Creek targeting step out drilling and resource expansion. 19,000 metres of planned drilling is underway across ten drill pads, with the goals of infilling and increasing confidence in the current inferred resource, and extending the current resource, which remains open 400 m to the north and unconstrained at depth.
The 19,000m of drilling will provide detail for the Pre-Feasibility Study (PFS) that is planned for H2 2026 ahead of the anticipated mine permit application.
