NVA Nova Minerals Limited

Nova Minerals Limited (“Nova” or the “Company”) (NASDAQ: NVA) (ASX: NVA) (FRA: QM3) is pleased to announce soil and rock chip assay results from its 2024 exploration season confirming a continued abundance of high-grade antimony at its Styx prospect, within its over 500km2 flagship Estelle Gold and Critical Minerals Project located in the Tintina Gold Belt in Alaska.

Highlights

• Follow-up reconnaissance mapping and sampling has proven an extensive antimony rich quartz-stibnite vein system with grades up to 54.1% Sb.
• Best 2024 surface sampling results at Styx include (Table 1 and Figures 5 and 6):
  • 54.1% Sb
  • 39.1% Sb
  • 28.0% Sb, 2.8 g/t Au
  • 20.7% Sb
  • 3.0% Sb, 5.6 g/t Au
  • 1.0% Sb, 5.5 g/t Au
  • 0.3% Sb, 9.8 g/t Au
• The main Styx occurrence is a ~1m thick quartz-stibnite vein (50% stibnite) with excellent outcrop exposure over 20m (Figure 2).
• Samples from the main vein occurrence in 2023 measured 19% and 21.7% Sb (ASX Announcement 10 October 2023). Additional sampling of splays around this occurrence show the anomaly likely extends over a 150m strike length (Figure 5).
• A 500kg bulk sample was also collected for metallurgical test work (Figure 4).
• Nova Minerals, through its 100% owned subsidiary Alaska Range Resources LLC, became a member of the Defense Industrial Base Consortium (DIBC) over 6 months ago, 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.

Nova Head of Exploration, Mr Hans Hoffman commented: “Field crews visited the Styx prospect this year to follow-up on the initial Antimony discovery made in 2023. There was so much stibnite just sitting on surface that we soon realized this would be too much to carry out, but it was also too impressive to leave behind. We were sitting on 500kg of potentially high-grade material in no time and brought it back to camp for metallurgical test work. We believe that plenty more remains as we look deeper into the Styx occurrence.”

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 1).

Assay results from soil and rock chip samples collected from the Styx prospect have all been received and are 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.

Styx Surface Sampling

Field crews collected a total of 11 rock samples at Styx, 6 of which were greater than 1 g/t Au or 1% Sb, including a high of 9.8 g/t Au and 54.1% Sb. 10 soil samples were also collected in the vicinity of Styx. Table 1 provides a summary of the gold, antimony, and gold equivalent grades for the 11 rock samples collected.

The majority of the sampling focused on the main vein occurrence (Figure 2) and splays running oblique to it. The quartz-stibnite veins are hosted in the hornfelsed Kahiltna flysch sedimentary rocks. A quartz diorite intrusive rock (E406939) containing mm-scale quartz calcite veins was sampled close to the main stibnite occurrence. Quartz monzonite dikes were sampled further to the west and to the south (E406797) of occurrence but were weakly mineralized.

Figure 2. Styx quartz-stibnite vein (~1m x 20m exposure)

Sample E406941 had the highest antimony content at 54.1%. As shown in Figure 3, it exhibits well-developed crystals with shiny metallic luster. This sample was from a newly discovered outcropping quartz vein located approximately 130 meters southwest and 100 meters in elevation below the main occurrence. This may be an extension of the main occurrence, but is difficult to determine due to the undulating nature of both the veins (Figure 5).

Figure 3. Sample E406941: 54.1% Sb

In addition to the sampling shown above, a 500kg bulk sample was collected for metallurgical testing. It was collected from surface material at the main vein and from splays above it. This sample material is shown in Figure 4 below.

The 2024 sampling results - along with 2023 shown as transparent - are shown below in Figure 5 (antimony) and Figure 6 (gold equivalent). Gold equivalent values were calculated using updated metals prices described below.

Gold Equivalent Calculation

Gold equivalent (AuEq) values were calculated using the formula below:

AuEq g/t= Au g/t + (Ag_ppm* XAg) + (Cu_ppm* XCu) + (Sb_ppm* XSb)

AuEq values were calculated using a gold price of $2,500/oz, a silver price of $30/oz, a copper price of $4/lb, and an antimony price of $25,000/ton, all with recovery rates of 90% as shown below.

Gold Equivalent Factors (XXx):

(XAg)= [US$30/oz silver price x 0.90 silver recovery] / [US$2,500/ troy ounce gold price x 0.90 gold recovery] = 0.012

(XCu)= [US$4/lb copper price x (1lb/14.583 troy ounces) x 0.90 copper recovery] / [US$2,500/ troy ounce gold price / 31.10348 grams per troy ounce x 0.90 gold recovery] = 0.000109715

(XSb)= [US$25,000/tonne antimony price x (1tonne/1000000grams) x 0.90 antimony recovery] / [US$2,500/ troy ounce gold price / 31.10348 grams per troy ounce x 0.90 gold recovery] = 0.000311035

Cautionary Statement: For many projects at the exploration results stage, metallurgical recovery information may not be available or able to be estimated with reasonable confidence. In such cases reporting of metal equivalents may be misleading.

Defense Industrial Base Consortium (DIBC) Membership and Grant Application Progress

Nova Minerals, through its 100% owned subsidiary Alaska Range Resources LLC, has been a member of the DIBC for over 6 months and has positively progressed with the resources and synergies it provides. The DIBC enables rapid research, access to commercial solutions for defense requirements, and innovations from industry, academia, and non-traditional contractors. DIBC members focus on identifying, developing, and testing cutting-edge capabilities at the speed of innovation.

Recognizing the potential of its antimony discovery early on, Nova is now well advanced within the Dept of Defense (DoD) grant application process to potentially rapidly develop its antimony and other critical minerals prospects identified across the Estelle Gold and Critical Minerals District. The Company looks forward to keeping the market updated on this progress.
