Nova Minerals Limited (NASDAQ: NVA) (ASX: NVA) (FRA: QM3)  is pleased to announce further broad, near-surface gold results from its RPM North deposit, within the Company’s flagship Estelle Gold and Critical Minerals Project, located in the prolific Tintina Gold Belt in Alaska.

Highlights

• 2025 drilling extends the halo around the high-grade core zone at RPM North with further broad intercepts and a new eastern discovery. RPM Valley results from the high-grade zone expected shortly.
• Broad near-surface gold intersections continue at RPM North, with the 2025 drill program confirming the eastern strike extension and infill results expected to support potential upgrades to the existing Measured and Indicated Mineral Resources at the main deposit, in support of the Feasibility Study (FS). Significant results include (Table 1, and Figures 3 and 5):

• RPM-080
  • 180m @ 0.7 g/t Au from 4m, including;
  • 108m @ 1.1 g/t Au from 4m
  • 27m @ 2.5 g/t Au from 11m, and
  • 7m @ 8.1 g/t Au from 11m
  • 2m @ 19.7g/t Au from 15m

• RPM-078
  • 162m @ 1.0 g/t Au from 3m including;
  • 54m @ 1.6 g/t Au from 109m
  • 7m @ 6.6 g/t Au from 147m, and
  • 2m @ 15.1 g/t Au from 147m
• RPM-068
  • 167m @ 0.7 g/t Au from 187m, including;
  • 123m @ 0.9 g/t Au from 201m
  • 75m @ 1.1 g/t Au from 242m

• RPM-070
  • 165m @ 0.6 g/t Au from 3m

• These strong results follow previous drilling and support the continuity of mineralization to the east, highlighting potential resource upside, where earlier drilling (RPM-004) intersected 259m @ 0.5 g/t Au from surface (ASX Announcement: 18 October 2021).

• Additional drill results will be released once received and reviewed under Nova’s QA/QC procedures, after which an updated Mineral Resource Estimate (MRE) will incorporate results from the 2023–2025 drill programs.
• FS-level studies are ongoing, with METS Engineering undertaking additional metallurgical test work to build on the high gold recoveries achieved at RPM to date (ASX Announcement: 5 August 2025), Rough Stock Mining is conducting mining studies, and Whittle Consulting is completing optimization studies.
• Results from the extensive soil and rock chip surface samples taken from across the project area in 2025 will also be reported once received and processed.

Nova CEO, Mr Christopher Gerteisen, commented:

“The latest drilling results at RPM North are excellent and importantly, support the continuity of mineralization across the deposit and indicate that a zone of further mineralization extends to the east, which remains open along strike. This eastern extension has the potential to significantly increase the resource at RPM and will be a focus of the 2026 RPM resource drilling program.

RPM continues to demonstrate the exciting potential of Estelle as a future, tier-one North American gold project. We plan to build on the successes achieved to date, with further exploration aimed at identifying additional mineralization in 2026. All results will be incorporated into an updated resource estimate for the upcoming FS.

“Technical studies and optimization work are progressing to advance the project towards commercial production, and we will keep shareholders informed as relevant studies are completed to realize further value from the Estelle Gold and Critical Minerals Project.”

2025 RPM North Drilling Summary

A total of seven diamond core holes were drilled at RPM North in 2025, designed to:

• Follow-up previous drilling to the East, where hole RPM-004 intersected 259m @ 0.5 g/t Au from surface (ASX Announcement: 18 October 2021)
  •  Conduct infill drilling at the main RPM North deposit to increase resource confidence
  •  Add definition to the southern boundary of the ore zone
  •  Test the connection with RPM Valley to the west

The latest diamond core drill results continue to increase resource confidence at RPM North, as well as adding new resource potential to the east. Holes RPM-068, RPM-070, and RPM-080 all intersected approximately 20m or so of granodiorite before transitioning to hornfels predominantly for the remainder. Mineralization occurs within sheeted to stockwork quartz and quartz-tourmaline veins. A large portion of these holes exhibited moderate to strong fractures with clay gouge and healed brecciated zones. These fractured zones contain moderate to strong argillic alteration. Hole RPM-080 had a high-grade intersection of 19.7 g/t Au from 15.2m to 17.6m, which can be attributed to the patchy and disseminated arsenpyrite shown in the two photos below.

Hole RPM-074 tested the southwestern extension of the mineralized intrusive and intersected hornfels at approximately 80m.

Hole RPM-076 was abandoned at 37m due to being set at the wrong dip, it was redrilled as hole RPM-078, which was designed to provide infill to the main deposit. The hole was collared in granodiorite and reached the northern contact with hornfels at approximately 125m, which remained the dominant lithology to the end of the hole.

RPM-072 was designed to test the connection between RPM North and RPM Valley and will be presented with the Valley results.

Detailed structural mapping, geophysical surveying, and geochemical sampling were conducted to vector towards the source intrusive. RPM North has exciting resource upside to the east, where drill holes RPM-004, RPM-068, and RPM-070 show extensive intervals of moderate-grade gold hosted in the Kahiltna flysch sedimentary rocks.

Data Verification

For the 2025 diamond core drilling program, core samples were cut in half and crushed to achieve >90% passing a 2mm sieve and split down to 225 g to 275 g samples at Nova’s on-site prep facility. Samples were then sent to ALS Fairbanks for additional prep and chemical analysis. Duplicates were collected every 1 in 20 samples at the same time using the same method (riffle split) as the parent sample. Blank material was inserted 1 in 40 samples. Standard Reference Material (SRM) was inserted 1 in 20 samples. Three different SRMs at three different grades levels were used.

ALS is a certified commercial laboratory and is independent of Nova Minerals. Samples are tested for gold using ALS Fire Assay Au-ICP21 technique. This technique has a lower detection limit of 0.001 g/t with an upper detection limit of 10 g/t. If samples have grades in excess of 10 g/t then Au-GRA21 is used to determine the over detect limit. Au-GRA21 has a detection limit of 0.05 g/t and an upper limit of 10,000 g/t. Four acid digestion with ICP-MS finish (ME-MS61) was used to evaluate 48 different elements.
