Nova Minerals (NVA) reports Korbel drilling and 4.05 Moz resource
Rhea-AI Filing Summary
Nova Minerals Limited reports new shallow drilling results from the Korbel Main Deposit at its Estelle Gold and Critical Minerals Project in Alaska, confirming a near-surface higher-grade core that could support a starter pit. The work targets part of Korbel Main’s pit-constrained resource of 275 Mt at 0.3 g/t gold for 2.70 Moz within the broader Korbel Gold Deposit, which totals 4.05 Moz including the Cathedral Deposit.
The 2025 reverse circulation program drilled 14 short holes and returned intercepts such as 19 metres at 0.6 g/t gold from surface, 25 metres at 0.5 g/t from 1 metre, and 22 metres at 0.7 g/t from surface, with grades locally up to 1.2 g/t. Nova highlights the potential for a pilot starter pit of about 250 metres by 80 metres by 20 metres to supply material for ore sorting, building on prior test work where 0.4 g/t material was upgraded to over 6 g/t, which could lower processing costs and increase production. The company notes that, at gold prices around US$4,600/oz, the combined Korbel resource is expected to be important to the ongoing feasibility study and overall Estelle project economics.

Exhibit 99.1
Nova Confirms Higher-Grade Starter Pit Potential within the 4.05 Moz Pit-Constrained Korbel Gold Deposit
Anchorage Alaska, January 21, 2026 - Nova Minerals Limited (“Nova” or the “Company”) (NASDAQ: NVA) (ASX: NVA) (FRA: QM3) ) is pleased to announce shallow reverse circulation drilling results within a proposed starter pit at the Korbel Main Deposit within the Company’s flagship Estelle Gold and Critical Minerals Project (Estelle or the Project), located in the prolific Tintina Gold Belt in Alaska.
Highlights
| ● | 2025 shallow RC drilling defines a near-surface higher-grade core at the bulk-tonnage Korbel Main Deposit, with grades up to 1.2 g/t Au. |
| ● | Results indicate a pilot starter pit approximately 250m long by 80m wide may be suitable within Korbel Main, with drilling identifying a higher-grade core within its bulk-tonnage pit-constrained resource of 275 Mt @ 0.3 g/t Au for 2.70 Moz Au (Table 3). |
| ● | Korbel Main forms part of the broader Korbel Gold Deposit, which includes the Cathedral Deposit, currently hosting a pit-constrained 1.35 Moz Au resource (150 Mt @ 0.3 g/t Au – Table 3). |
| ● | With gold prices currently around US$4,600/oz, the combined 4.05Moz Au (Table 3) Korbel bulk-tonnage pit-constrained resource is anticipated to materially contribute to Project economics under evaluation in the ongoing feasibility study (FS). |
| ● | Highlights from the 2025 shallow, closely spaced, infill 14-hole reverse circulation (RC) drill program at Korbel include (Table 1 and Figure 4): |
| ○ | KBRC_001 |
| ■ | 19m @ 0.6 g/t Au from surface including; | |
| ■ | 6m @ 1.0 g/t Au from 9m |
| ○ | KBRC_006 |
| ■ | 25m @ 0.5 g/t Au from 1m including; | |
| ■ | 8m @ 0.8 g/t Au from 13m |
| ○ | KBRC_010 |
| ■ | 9m @ 1.2 g/t Au from 1m |
| ○ | KBRC_011 |
| ■ | 26m @ 0.7 g/t Au from 1m |
| ○ | KBRC_013 |
| ■ | 22m @ 0.7 g/t Au from surface including; | |
| ■ | 9m @ 1.1 g/t Au from surface |
| ● | While RC drilling is significantly shallower than diamond core drilling, with average hole depth ~20m, the results highlight the potential for a pilot pit to further test ore sorting, building on previous work where 0.4 g/t Au material was successfully upgraded to over 6 g/t Au - more than a tenfold increase - potentially reducing processing costs and increasing mine production (ASX Announcement: 15 March 2021). |
| ● | The 2025 RC drill program focused on adding resource confidence to intercepts identified in previous diamond drilling campaigns, including: |
| ● | KBDH-002: 540m @ 0.3 g/t Au from 2m, incl. 158m @ 0.5 g/t Au (ASX Announcement: 22 June 2020) | |
| ● | KBDH-004: 517m @ 0.3 g/t Au from 1m, incl. 106m @ 0.7 g/t Au (ASX Announcement: 14 July 2020) | |
| ● | KBDH-012: 429m @ 0.6 g/t Au from (ASX Announcement: 19 August 2020) |
| ● | To view a commentary video from Nova’s CEO, Christopher Gerteisen, discussing the significance of these latest drill results, please click here. |
| ● | All drill results from Korbel have now been reported. |
| ● | 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:
“We are pleased with the 2025 RC drilling results at Korbel Main, which have defined a near-surface, higher-grade core. The results highlight the potential for a pilot starter pit within Korbel Main’s 2.7 Moz bulk-tonnage pit-constrained resource and demonstrate strong potential to test ore sorting on a larger scale, building on previous work where material was upgraded more than tenfold, potentially lowering processing costs and increasing gold production.
“At current gold prices of around US$4,600/oz, the combined 4.05 Moz Korbel pit-constrained resource is expected to play a key role in the ongoing Estelle Project PFS, with additional material currently outside the US$2,000/oz pit shell anticipated to be included in the in-pit resource.
“We look forward to keeping the market informed as Korbel continues to progress towards production.
2025 Korbel Drilling Summary
A total of 14 RC holes were drilled at the Korbel Main Deposit (Figure 3) to provide infill definition to the core of the existing 2.7 Moz (275 Mt @ 0.3 g/t Au) pit-constrained resource (Table 3) for a potential higher-grade starter pit. Despite challenges from a shallow water table, sufficient sampling was achieved to increase confidence in the near-surface higher-grade mineralization. This will support planning for a potential early-stage pilot pit (~250m long x 80m wide x 20m deep) to produce ore for further ore sorting analysis (Figure 3). With gold concentrated in arsenopyrite-bearing quartz veins, previous test work has shown that Korbel ore is highly amenable to ore sorting, with the potential to upgrade material from 0.4 g/t Au to over 6 g/t Au, which could reduce processing costs and increase mine production (ASX Announcement: 15 March 2021).
Although grades at Korbel are lower than at RPM, it remains a significant bulk-tonnage deposit, and with gold near US$4,600/oz, Korbel is expected to make a meaningful contribution to the economics of the ongoing FS.
Figure 1 below shows a typical RC drilling site at Korbel. At each site, -60 degree holes were drilled at 230 and 050 azimuths, crosscutting the dominant northwest structural trend of the steeply-dipping sheeted veins.
Figure 1. Korbel RC drill site
All 2025 RC holes targeted the granodiorite of the main Estelle pluton, which is crosscut by mineralized quartz veins. Nova believes these results highlight a zone of increased vein density, the main driver of gold mineralization
RC chips were preserved in chip trays for microscope analysis, and some notable chalcopyrite, pyrite, and arsenopyrite were observed (Figure 2).

Data Verification
Where possible each 1.52m to 3.05m RC interval was riffle split (dry) to obtain 3-5 kg samples at the drill site, these samples were 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. Due to the presence of a water table, wet samples were bulk sampled at the drill and placed in a drying facility. After drying, samples were crushed to achieve >90% passing a 2mm sieve and split down to 225 g to 275 g samples. Samples were then sent to ALS Fairbanks for additional prep and chemical analysis. Field duplicates (RC) for recent data 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. 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.
