High Gold Recoveries Achieved at RPM

Ore sorting test work upgrades material by 4.33 times in one pass Gold recoveries of up to 68.7% achieved via heap leach

Highlights

• RPM conceptual flowsheet outlines clear path to high gold recoveries (Figure 6).

• High-grade ore over 2 g/t Au fed directly into the carbon in pulp (CIP)/carbon in leach (CIL) circuit to optimize gold recovery.

• Ore below 2 g/t Au will be processed through the ore sorter, where a 1,000 kg bulk test with Steinert Mining upgraded 1.32 g/t Au material to 5.72 g/t Au — an increase of 4.33 times in a single pass (Figures 1, 2 and 3).

• Lower-grade ore rejected by the sorter will undergo heap leaching, with column tests showing potential gold recoveries as high as 68.7% (Figure 4 and 5 and Table 1).

• Advanced sorting technology expect to increase the volume of high-grade feed to processing circuits, optimizie resources and maximize orebody value.

• Ongoing CIP/CIL test work for the Pre-Feasibility Study (PFS) aims to advance this part of the flowsheet.

• High pressure grinding rolls (HPGR) crushing test work is in progress to further optimize the flowsheet and provide power cost efficiencies in the PFS.

Nova Minerals CEO, Mr Christopher Gerteisen commented: “We are extremely pleased with the results emerging from our ongoing metallurgical test work program at the RPM Deposit, which we believe continues to demonstrate the exceptional quality and scalability of the Estelle Project.

The ability to extract up to 68.7% gold recovery from lower-grade material through heap leaching, combined with a 4.33 times upgrade using ore sorting technology, is a significant technical breakthrough, in our opinion. These results underscore the economic potential through innovative processing methods as we continue to refine our development pathway.

This multi-pronged flowsheet approach — incorporating ore sorting, heap leaching, and CIP/CIL processing has the potential to be a best-in-class strategy for maximum gold recovery, efficient capital deployment, and lower processing costs. We believe RPM has the hallmarks of a low-cost, high-margin gold producer.

With CIP/CIL test work well underway and further optimization on ore sorting and HPGR crushing still to come, we believe the upside could be significant. These preliminary results strengthen our

Nova Minerals Limited ( Nova or the Company ) ( ASX: NVA, NASDAQ: NVA, FRA: QM3 ) is pleased to announce results from the ongoing RPM gold prefeasibility metallurgical test work program which is showing exceptional recoveries , in our opinion, with potential further opportunities to optimize for even higher recoveries.

Ore Sorting Test Work Results

Particle density X-Ray Transmission (XRT) ore sorting is a proven technology which has been successfully implemented as part of the pre-treatment concentration process in many mines around the world. X-rays are used to examine the density of the rock being sorted in order to separate a target mineral, ore or element from waste prior to the haulage, crushing and processing mining stages. By rejecting a considerable proportion of the lower grade rock before processing through the mill, the mill feed grade is effectively increased and energy requirements and tailings generation are reduced, resulting in a more environmentally friendly mining operation with improved overall mine efficiencies and economic benefits.

The process starts with raw ore being scanned with X-rays and data collected from the detector. With the help of big data and intelligent algorithms, the ore and waste rock is separately identified and a high-pressure blower sprays the waste rock away to realize efficient automatic intelligent sorting.

Nova and METS Engineering (METS) partnered with Steinert Mining (Steinert) to evaluate RPM orebody amenability to sensor-based ore sorting.

Test work at Steinert was conducted in 2 stages with sighter test work undertaken followed by a large 1,000 kg bulk test. The result from the bulk test work program demonstrated the Estelle RPM ore is amenable to ore sort upgrading with a XRT and 3D-laser combination algorithm. Figure 2 illustrates the three stage test work process undertaken by Steinert to evaluate the amenability of the ore. Figure 3 presents the cumulative recovery, mass pull and grades obtained from the test work.

The results presented in Figure 2 demonstrated that a high density fraction can be recovered through ore sorting in which 48.8% Au is recovered in a mass yield of 11.3% in the first pass. This generated a concentrate of 5.72 g/t Au from a 1.32 g/t feed – a 4.33 times upgrade in the first pass through the

Heap Leaching Metallurgical Test Work Results

Heap leaching is a low capital and operating cost alternative to conventional mill processing techniques for gold recovery from lower grade ore sources. It is a well-proven and cost-effective approach used by the majors including Barrick Gold, Newmont, Kinross Gold’s Alaskan Fort Knox and Eldorado Gold’s Kışladağ mine to name a few.

Heap leaching can potentially recover the gold from 100’s of millions of tons of lower grade material, and the reject material from the ore sorters, which otherwise would be regarded as waste. This has the potential to significantly increase the gold production from the project.

Figure 4 below shows how a typical heap leach process works with ore put through an optional preapplication phase before being stacked on an impermeable heap pad. The pad is then irrigated with a leaching agent for an extended period of time which chemically reacts with the ore to dissolve the gold into a solution as it percolates through the heap. The impregnated solution is then collected at the bottom of the heap and the gold is recovered though a gold processing plant, with the barren solution recycled to start the process again.

Figure 4. A typical heap leach process

Heap leaching has a number of benefits including:

• Recovers low grade gold from ore that was previously sent to waste, resulting in higher potential gold production.

• Lower capital cost relative to other methods of gold recovery, as with only higher-grade ore now going through the plant, a smaller plant is required.

• Simple process with lower operating costs than conventional processing techniques (lower energy consumption, less equipment configuration).

• Can move a project to cashflow at a quicker pace and generate the capital required to finance the more expensive processing facilities.

• Suitable for all climates eg: The Fort Knox gold mine in Alaska uses heap leaches to extract gold.

Nova engaged METS Engineering to undertake test work to evaluate the amenability of RPM to heap leaching. METS undertook a comprehensive prefeasibility heap leaching test work program on low grade RPM ore. The program consisted of crush size sensitivity testing, agglomeration and percolation testing and culminated in four heap leach column tests. The material used in the column test was crushed using High Pressure Grinding Rolls (HPGR).

Table 1 presents the results of the column leach test work which shows that at an achievable crush size of 3.35 mm after 59 days of leaching 68.7% gold extraction can be achieved from RPM low grade ore. Cyanide consumption ranged from 0.61 to 0. 92 kg per ton of ore. Lime consumption ranged from 0.081 to 0.139 kg per ton of ore. Both reagent consumptions are reasonable for heap leaching.

RPM Conceptual Flowsheet

Based on the positive test results Nova is pleased to present a high level conceptual flowsheet for RPM processing that is being further developed with test work and engineering underway.

This flowsheet demonstrates the capability to fully utilize the RPM resource combining Steinert Ore Sorting Technology, Heap Leaching and CIP/CIL. The high-level conceptual flowsheet is presented in Figure 6.

The implementation of ore sorting technology is designed to allow for the upgrading of low-grade RPM mined ore to high grade concentrate appropriate to feed a CIP/CIL plant. The rejects from the ore sorter will then be heap leached in a suitably sized operation to maximize the recoverable gold from the RPM deposit. Additional engineering and economic trade-off studies will be conducted to determine the optimum size of the heap leach operation and CIP/CIL plant to achieve the best economic outcomes for the Estelle project.

Section 1 Sampling Techniques and Data

Criteria	JORC Code Explanation	Commentary
Sampling techniques	• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse Au that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.	• Core is systematically logged from collar to EOH characterizing rock type, mineralization, and alteration. Oriented core measurements of structural features are taken where appropriate. Geotechnical measurements such as recoveries and RQDs are taken at 10-foot (3.05 m) intervals. Samples are taken each 10 feet (3.05m) unless there is a change in lithology, whereby <3.05m selective samples may be taken. In these cases samples are broken to lithologic boundaries. Samples are then half cut with one of the half cuts being sent to the ALS lab in Fairbanks Alaska for processing. The remaining half core is returned to the box and safely stored as reference material..
Drilling techniques	• Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type,	• HQ diamond core triple tube, down hole surveys every 150 feet (~50m), using a Reflex ACT-III tool.

Criteria	JORC Code Explanation	Commentary
Data aggregation methods	• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated.	• Widths are report as core length. Future true widths will be calculated by measuring the distance perpendicular to the dip of the mineralized zone on any given cross section that the intercept appears on. Two holes per section are required to calculate true thickness. No “Top Cap” has been applied to calculation of any intercepts. A “Top Cap” analysis will be completed during a future Resources Study and applied if applicable. Widths of intersection are calculated by applying a weighted average (Sum [G x W] / Sum [W]) to the gold values and reported widths within any given intercepts. The CP will visually select the intercept according to natural grouping of higher-grade assays. Zones of internal dilution my vary depending on the CP discretion as to what is geologically significant. Sub intersection of higher grades within any given intercepts may be broken out if present. • An overall average grade cut-off of 0.1g/t and a maximum of 6 meters of internal dilution was used.
Relationship between mineralisation widths and intercept lengths	• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’)..	• See above.
