Nova Minerals Finds Gold up to 141 g/t Au from Rock Samples at the Stibium Antimony-Gold Prospect on its Estelle Gold and Critical Minerals Project, in Alaska

/EIN News/ -- Anchorage, Alaska, Dec. 11, 2024 (GLOBE NEWSWIRE) -- Nova Minerals Limited (“Nova” or the “Company”) (NASDAQ: NVA) (ASX: NVA) (FRA: QM3) is pleased to announce gold rock chip assay results from its 2024 exploration season confirming an extensive 800m long by 400m wide gold and antimony rich zone at its Stibium prospect, within its over 500km2 flagship Estelle Gold and Critical Minerals Project located in the Tintina Gold Belt in Alaska..

Highlights

• Assay results for gold on the rock chip samples taken as part of the 2024 follow-up reconnaissance mapping and sampling program has now proven that the Stibium prospect is an extensive gold and antimony rich zone with grades up to 141 g/t Au and 60.5% Sb (ASX Announcement: 10 October 2023).
  
• Seven samples greater than 20 g/t Au, and 16 samples greater than 5 g/t Au.
  
• Best 2024 rock sampling results for gold at Stibium include (Table 1 and Figure 1):
  
  
  • 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 2024 rock sampling results for antimony previously reported at Stibium include (ASX Announcement: 20 November 2024 and Figure 2):
  
  
  • 56.7% Sb
  • 55.7% Sb
  • 54.8% Sb
  • 54.5% Sb
  • 46.2% Sb
  • 45.9% Sb
  • 43.3% Sb

• Samples from the initial discovery in 2023 measured up to 12.7 g/t Au and 60.5% (ASX Announcement: 10 October 2023).
• 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.
• Awaiting further soil sample assay results for Stibium.
• Results incoming on the remainder of the 2024 sampling, including further regional exploration from the broader RPM and Stoney areas.

Nova CEO, Mr Christopher Gerteisen commented: “We are delighted to now report both high-grade antimony and gold at the Stibium prospect. Both antimony and gold are currently at record high prices and continuing on a clear upward trajectory, potentially marking the beginnings of a bull market for both. This is an exciting time for the Company with the Estelle Gold and Critical Minerals project in the right place, at the right time, with the right commodities.”

Nova Head of Exploration, Mr Hans Hoffman commented: “As we have stated in the past, we were looking for gold and the antimony found us, but in the case with Stibium in 2024, we were delineating the impressive antimony discovery from 2023, and it looks like the gold found us. These high-grade gold and antimony values occur over approximately 200m of vertical relief which makes Stibium a top drill target for 2025.”

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 been received and 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), and
  

Assay results for gold from rock samples collected at the Stibium prospect have now been received and 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, 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.

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. 180 soil samples were also collected from the area, with assay results still outstanding for both gold and antimony. 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.

Table 1 provides a summary of the gold and antimony grades in all rock samples greater than 5 g/t Au..

Table 1. Top gold rock sample results at Stibium

A 2,500kg bulk sample was collected at the location of the inset shown in Figures 1 and 2 above (ASX Announcement: 10 September 2024 and 5 December 2024). This sample was collected in a hydrothermal breccia hosted in hornfels near the contact with a quartz diorite. A total of 8 rock chip samples were collected over a 3.5m wide zone which is representative of the bulk sample material (Insets in Figures 1 and 2, and Figure 3) returning a high of 17.6 g/t Au with an average composite grade of 10.3 g/t Au and 0.5% Sb, as evidenced in Table 2 below. It should be noted that the location for the bulk sample was selected from geological observations indicating the coincidence of antimony with high-grade gold which has been proven in the assay results. Zones of more intense Stibnite veining yielding significantly higher antimony grades up to 56.7% Sb were later identified across the prospect area (Figure 2). The company plans to collect further bulk samples from these additional high-grade antimony zones.

Sample E406756 (17.6 g/t Au) was the second sample collected in the composite chip sample through the hydrothermal breccia zone shown above. Figure 5 below shows a similar style of mineralization found 130 meters to the south in samples E406779 (18.1 g/t Au, 0.6% Sb) and E406780 (62.3 g/t Au). Mapping the extent of the hydrothermal breccia was difficult due to the nature of the terrain, but 2025 drilling will seek to intercept these gold-rich structures.
