RUA GOLD Reports Extensions Along Strike and at Depth at the Auld Creek Gold-Antimony Project, Reefton Goldfield
Rhea-AI Summary
Rua Gold (NZAUF) reported step-out drilling at Auld Creek that extends mineralization along strike and to depth, with high-grade intercepts and a fully funded 19,000m drill program currently operating four rigs and a fifth rig planned for April.
Highlighted intercepts include 1.4m @ 29.1 g/t AuEq and multiple multi-meter gold-antimony zones; key assays for northern and deep step-outs remain pending.
Positive
- Resource extension by 400m north, extending deposit beyond 1,000m
- Depth continuity demonstrated to 540m below surface (ACDDH065/063 pending assays)
- High-grade intercept 1.4m @ 29.1 g/t AuEq (ACDDH058)
- Fully funded 19,000m drill program with four rigs active and a fifth rig planned in April
Negative
- Key step-out assays for ACDDH064 and ACDDH065 are pending, delaying confirmation of extensions
- Some intercepts reported as narrow true widths, requiring further drilling to define mineable continuity

Vancouver, British Columbia--(Newsfile Corp. - March 17, 2026) - Rua Gold Inc. (TSX: RUA) (NZX: RGI) (OTCQX: NZAUF) (WKN: A40QYC) ("RUA GOLD" or the "Company") is pleased to provide an exploration update on its Auld Creek gold-antimony Project located in the Reefton Goldfield on the South Island of New Zealand.
Highlights:
Recent drilling provides strong evidence for expansion of the gold-antimony resource:
ACDDH064 intercepted mineralization 400m north of the resource envelope, confirming surface extension beyond 1,060 meters (previously 870m length).
ACDDH065 intercepted mineralization 550m downhole, demonstrating continuity to 540m below surface (previously 300m depth).
Assays are pending for both holes. The resource remains open along strike to the north and at depth, with mineralization occurring in plunging shoots.
Highlighted assay results from recent step-out drilling at Auld Creek include:
ACDDH058: 1.4m @ 29.1 g/t AuEq1 (25.5 g/t Au &
1.6% Sb) from 173mACDDH059: 1.2m @ 14.3 g/t AuEq1 (7.6 g/t Au &
3.1% Sb) from 270mACDDH060: 2.8m @ 3.8 g/t AuEq1 (2.5 g/t Au &
0.6% Sb) from 128mACDDH062: 4.3m @ 2.5 g/t Au from 349m
The project remains on track with mine planning, environmental, and social studies to support submission of a Fast-track2 Referral application at the end of the month.
All drill-holes in the recent campaign have reliably intersected the structure, supporting its interpretation as a continuous, district-scale feature.
The higher gold grade intersected in ACDDH058 helps delineate the orientation and continuity of high-grade mineralized shoots, confirming the deposit's potential to host high-grade gold zones.
Scout drilling has been mobilized to test the full 2,500m length of the surface gold-arsenic-antimony soil geochemical anomaly.
The Company's CEO, Robert Eckford, commented, "The decision to prioritize the Auld Creek gold-antimony project for a major development drilling program is already delivering encouraging results, with both resource step-out drilling, and scout drilling of outlying targets demonstrating consistent geological and structural continuity. The early results support our decision to simultaneously undertake a Preliminary Economic Assessment ("PEA") as part of a Fast-Track referral application for a mining permit expected to be submitted at the end of the year."

AULD CREEK EXPLORATION UPDATE
Recent drilling provides strong evidence supporting expansion of the Auld Creek gold-antimony resource over 1,000m length and more than 500m of depth; together with several higher-grade gold intercepts that highlight the potential for high-grade mineralization hosted within orogenic-style quartz veins.
These results provides early evidence and support the Company's focus on its fully funded 19,000m drill program, with four diamond drill rigs currently operating on site.
Details on each reported intercept:
- Hole ACDDH058 in the northern end of the Fraternal resource envelope returned high gold grades, 0.5m @ 20.5 g/t Au, 0.2m @ 83.4gm/t Au and 0.7m @ 12.6 gm/t Au +
3.3% Sb (estimated true width of 7.3m). This is the highest individual gold assay grade in the Auld Creek deposit to date and importantly assists in delineating the orientation and continuity of high-grade mineralized shoots.
Approximately 65m down dip of ACDDH058, hole ACDDH060 intersected 2.8m @ 2.5 g/t Au &0.6% Sb (estimated true width of 10.8m). This intercept confirms structural continuity and suggesting the high-grade mineralized shoot plunges moderately south.
- ACDDH059 and 062 provide better understanding of the central Fraternal zone.
ACDDH059: 1.2m @ 7.6 g/t Au + 3.07 % Sb including 0.55m @ 14.1 g/t Au +3.3% Sb (estimated true width 2.6m)
ACDHH062: 8.5m @ 1.73 Au including 0.2m 11.8 g/t Au, and 0.3m 5.8 g/t Au (estimated true width 5.0m)
- ACDDH063 and 065 provide definitive proof of depth continuity in the northern and southern Fraternal zone, driving the resource envelope down 540m below surface (pending assays).
- ACDDH064 has intercepted a strong mineralized zone 400 meters north of the current resource extending it over 1,000m (pending assays).
- Surface geochemistry continues to provide a strong vector toward mineralisation, the signature continues over 2,500m (1,500m beyond the current resource envelope).
- Scout drilling targeting northerly extensions of the Fraternal and Bonanza lodes is planned along with the intensive resource development drilling of the central Fraternal deposit.
All drill-holes in the recent campaign have successfully intersected the Fraternal structure, supporting its description as a continuous and district size feature. Further infill and extensional drilling is planned, along with geological modelling and geochemical fingerprinting of the lodes and host greywacke/argillites to provide improved geological and structural understanding of the deposit.
Collectively, these results materially advance the Company's understanding of the Auld Creek system providing clear vectors to guide subsequent drilling focused on expanding higher-grade mineralization along plunge toward the north and at depth.
