Nova Minerals Identifies Stibium Gold-Antimony Resource Drill Targets on its Estelle Gold and Critical Minerals Project, in Alaska

Anchorage Alaska, Jan. 13, 2025 (GLOBE NEWSWIRE) -- Nova Minerals Limited ("Nova" or the "Company") (NASDAQ:NVA) (ASX: NVA) (FRA: QM3) ) is pleased to announce assay results for gold and antimony from soil samples collected at the Stibium prospect have now been received and have identified high-grade resource targets within the previously identified 800m long by 400m wide zone at Stibium within the Company's over 500km2 flagship Estelle Gold and Critical Minerals Project located in the Tintina Gold Belt in Alaska.

Highlights

• New drill-ready broad structurally controlled gold and antimony zones identified at Stibium through systematic ground exploration.

• US grant applications for antimony and critical minerals development progressing

• Assay results for soil and rock chip samples taken as part of the 2024 follow-up reconnaissance mapping and sampling program have now proven the Stibium prospect is an extensive gold and antimony rich zone with grades up to 141 g/t Au and 60.5% Sb (Announcements: 10 October 2023, and 5 and 11 December 2024).

• 180 soil samples collected to delineate the mineralized zone. 35 soil samples greater than 1 g/t Au with a high of 25.6 g/t Au. 10 soil samples greater than 0.1% Sb with a high of 2.8% Sb. For soil samples, grades > 1 g/t Au and > 0.1% Sb are considered high-grade (Table 1 and Figures 1 and 2).

• Best rock sampling results for gold previously reported at Stibium include (Announcement: 11 December 2024, and Figure 2):

	141.0 g/t Au
	64.7 g/t Au
	62.3 g/t Au
	42.8 g/t Au
	34.8 g/t Au
	29.1 g/t Au
	22.3 g/t Au

• Best rock sampling results for antimony previously reported at Stibium include (Announcements: 10 October 2023 and 5 December 2024, and Figure 1):

	60.5% Sb
	56.7% Sb
	55.7% Sb
	54.8% Sb
	54.5% Sb
	46.2% Sb
	45.9% Sb
	43.3% Sb

• The Stibium gold-antimony occurrence is hosted in quartz diorite intrusive rocks and hornfels sedimentary rock over an approximately 800m long by 400m wide zone, and remains open.

• Results incoming on the remainder of the 2024 sampling, including further regional exploration from the broader RPM and Stoney areas.

• Nova Minerals, through our 100% owned subsidiary Alaska Range Resources LLC, is a member of the Defense Industrial Base Consortium (DIBC), and as an early mover is well advanced with the Dept of Defense (DoD) grant application process.

• Antimony is listed as a critical and strategic mineral to US economic and national security interests by the US Department of Interior. The European Union also has antimony on their critical materials list and both are 100% import reliant.

• China, which produces ~54% of the worlds antimony, recently banned all exports of the critical mineral to the US (See news article here).

Nova Head of Exploration, Mr Hans Hoffman commented: "With the final soil results received we can clearly see from the heat map the extent of this impressive gold and antimony anomaly. The main ridge at Stibium offers great access to the north and the south where we intend to drill the identified high-grade stibnite veins, gold-bearing quartz veins, and the mineralized hydrothermal breccia. The ridge will provide for easy startup in 2025 requiring minimal drill pad construction and easier access to water due to its lower altitude than other Estelle prospects."

Nova CEO, Mr Christopher Gerteisen commented: "The Stibium prospect now has a very well defined high-grade gold-antimony target that is ready for resource drilling. Defining a gold-antimony resource at Stibium and advancing towards antimony production is a top priority for the company which is seeking U.S. government grant funding to aggressively pursue this opportunity. We are currently preparing and gearing up to commence 2025 field activities as soon as possible, which includes resource drilling programs at Stibium and RPM. The Estelle Gold and Critical Minerals Project is in the right place, at the right time, with the right commodities."

2024 Exploration Mapping and Sampling Program Results

During the 2024 field season Nova's Head of Exploration, Mr. Hans Hoffman, continued the surface exploration mapping and sampling program across the Estelle claim block with a particular focus on following up results at prospects identified in the 2023 season. 511 soil samples, 225 rock samples, and approximately 5 tons of bulk sample material were collected across the property (Figure 3).

As a result of that program, and reported to date:

• Assay results from soil and rock chip samples from the Styx prospect identified high-grade antimony (Sb) and gold in outcrop, with grades up to 54.1% Sb and 9.8 g/t Au (ASX Announcement: 22 November 2023).
  
  
  
  
• Assay results from soil and rock chip samples collected from the Muddy Creek prospect, with a high of 128.5 g/t Au, have extended the high-grade gold mineralization zone by a further 400m to 800m in length now. Muddy Creek is considered to be one of the most impressive gold anomalies on the claim block to date (ASX Announcement: 27 November 2024).
  
  
  
  
• Assay results for antimony from rock samples collected at the Stibium prospect have identified an 800m long by 400m wide antimony rich zone with results of up to 56.7% Sb and 11 samples grading > 30% Sb (ASX Announcement: 5 December 2024).
  
  
  
  
• Assay results for gold from rock samples collected at the Stibium prospect show the previously identified 800m long by 400m wide zone is rich in both gold and antimony, with gold results of up to 141 g/t Au and seven samples greater than 20 g/t Au (ASX Announcement: 11 December 2024), and
  
  
  
  

Assay results for gold and antimony from soil samples collected at the Stibium prospect have now been received and have identified high-grade resource targets within the previously identified 800m long by 400m wide zone, as reported in this announcement.

Further results from the soil and rock chip samples taken from across the project area in 2024 will be reported once received and processed.

Figure 1 below highlights the antimony targets identified in both rock and soil samples. Previously reported high-grade antimony results from rock samples are labeled on this figure, and a heat map was interpolated from the soil samples. Sample density was sufficient to interpolate between points, however, a gap in samples to the southwest exists due to terrain challenges. This zone could improve with additional sampling, as quartz vein stockwork in hornfels was noted in float below along the lowest traverse. The interpolation of the soils data highlights three main pods of high-grade antimony (> 1000 ppm Sb). High-grade antimony was observed in stibnite veins in outcrop above the two southern anomalies. It is anticipated these veins will be intersected in the proposed 2025 drill core while targeting the soil geochemical anomalies.

Figure 2 below highlights the gold targets identified in both rock and soil samples. As with Figure 1, high-grade rock samples (> 10 g/t Au) are labeled, and a heat map was interpolated from the soil samples. The heat map shows gold mineralization is wide-spread at the Stibium prospect, and that the anomalous gold coincides with the high-grade antimony targets.

Also to note on Figures 1 and 2 are the proposed drill pad locations on the top of the ridge as well as an access trail that has been designed from the LiDAR and air photo data collected in the summer of 2024.

Stibium Surface Sampling

Field crews conducted an extensive surface sampling program over the Stibium area in 2024 which specifically targeted gold and stibnite, which is the primary ore source for antimony. A total of 80 rock samples were collected, 7 of which were greater than 20 g/t Au, including a high of 141 g/t Au, and 11 of which were greater than 30% Sb, including a high of 56.7% Sb. 180 soil samples were also collected from the area. 35 soil samples returned values greater than 1 g/t Au with a high of 25.6 g/t Au. 10 soil samples returned values greater than 0.1% Sb with a high of 2.8%. The Stibium occurrence is hosted in quartz diorite intrusive rocks and hornfels sedimentary rock over an approximately 800m long by 400m wide zone, and remains open. Of particular interest is soil sample E397212 which measured 2.0 g/t Au which was the last sample along the traverse and a couple hundred meters southwest of the previously identified anomalous zone. Sampling above this area was difficult due to the topography, but 2025 reconnaissance will seek to expand on this zone where stockwork quartz veining in hornfels was noted.

Table 1 below provides a summary of the gold and antimony grades in the 35 soil samples greater than 1 g/t Au and the 10 samples greater than 1,000 ppm Sb which includes one sample at 0.56 g/t Au.
