Maiden gold resource of 2.5 million ounces confirms immense potential of Nova Mineral’s Estelle Gold Project
Investment highlights:
-
Independent Maiden Inferred JORC Resource of circa 2.5 million ounces of gold at Oxide Korbel (Blocks A and B) one of fifteen known occurrences at Nova Mineral’s Estelle Gold Project
-
The Oxide Korbel deposit (Blocks A and B) remains open at depth and along strike
-
Resource starts from less than 2 m from surface (ASX announcement: 2 September 2019 - Hole SE12-004)
-
Resource occurs on less then 1 % of the total project area
-
Future plans include multiple diamond drill rigs on site operating 24 hours 7 days a week, with a focus on increasing the drill density of the maiden resource, plus extensional drilling to grow the global resource
-
Further exploration drilling to test RPM and Shoeshine planned
-
Aggressive drilling campaign to continue upon receiving permits and approvals
Minerals explorer and developer Nova Minerals Limited (ASX:NVA FSE:QM3)(‘Nova’ or ‘the Company’) is pleased to announce its maiden Inferred Gold resource estimate for the Oxide Korbel prospect from the phase 1 resource drill programme at the Company’s Estelle Gold Project (‘the Project’).
An Independent Maiden inferred JORC Resource (‘the Resource’) of circa 2.5 million ounces of gold has been confirmed at the Project. The Oxide Korbel deposit (Blocks A and B), which is one of fifteen known occurrences, remains open at depth and along strike.
The Resource Estimate starts from less than 2 m from surface and occurs on less than 1 % of the total project area. The mineral deposit type is comparable to Kinross’ Fort Knox Gold and Victoria Gold’s Dublin Gulch Eagles Gold Mine.
Nova Minerals plans include multiple diamond drill rigs on site operating 24 hours 7 days a week, with a focus on increasing the drill density of the maiden resource, plus extensional drilling to grow the resource. Further drilling to test RPM and Shoeshine is also being planned.
NVA Managing Director, Mr Avi Kimelman said: “With credit to the team, the Oxide Korbel maiden Inferred Resource and represent a major milestone to Nova and highlights the immense potential of the Estelle Gold project as this is only one of multiple major occurrences. The Oxide Korbel Blocks A and B also remain open at depth and along strike. This is just a start and we have literally only scratched the surface.
Our aggressive drilling efforts will continue upon receiving permits and approvals, with exploration planning around the existing resource already underway. We intend to use multiple diamond drill rigs to define the footprint of Oxide Korbel deposit, expand the resource and test additional gold targets on the Estelle property (Figure 5) .
The Oxide Korbel deposit is a textbook example of a potentially bulk mineable, large scale, near surface, low strip Intrusion-Related Gold System (IRGS) mirroring that of Kinross’ Fort Knox Gold and Victoria Gold’s Dublin Gulch Eagle Gold Mine systems. The Estelle project is well located (Figure 6) for future development and the project receives strong government body and local support.”
Mineral Resource Estimate
This Mineral Resource Estimate has been prepared for Oxide Korbel gold deposit one of several gold targets on the Estelle Property. The Mineral Resources were estimated using drill hole data. The Mineral Resource estimate is summarized in JORC Table 1, Sections 1 to 3.

Geologic Interpretation - The property is situated within the Koyukuk terrane, one of several arc assemblages accreted late into the North American Cordillera. The
Nova Minerals Ltd. Level 17, 500 Collins Street, Melbourne, VIC, 3000. Phone: +61 3 9614 0600 Fax: + 61 3 9614 0550
property straddles the north-south trending axis of the Late Cretaceous / Early Tertiary Mt Estelle plutonic suite that intrudes the Latest Jurassic to Early Cretaceous Kahilltna Assemblage sediments. The Kahiltna Assemblage includes units of volcaniclastic sediments, siltstone and local conglomerate interpreted as flysch deposits deposited in a continental margin setting.
The Mount Estelle composite pluton is the southern-most pluton in the Yentna trend and has isotopic ages ranging from 68 – 78 Ma with many crystallization ages averaging 70 Ma. The Mount Estelle pluton is zoned from a granite core to more mafic marginal phase. Xenoliths of the country rocks and of the various intrusive phases occur throughout the pluton. Sheeted joint sets and unusual spherical, onion-skin-like features occur in core areas of the pluton. Adjacent to the Mount Estelle pluton, the country rock is hornfelsed and locally exhibits red staining and sericite-clay alteration, and pyrite in disseminations and along fractures.
The Estelle gold deposit is interpreted to be a reduced intrusion-related gold system (IGRS). The main geologic characteristics of the Estelle deposit are remarkably similar to those of the Fort Knox and Dublin Gulch gold deposits which are also located in the Tintina Gold Belt (Nova Minerals News Release June 19, 2019)
A satellite image study of the entire Estelle property was completed by Michael Baker in 2019 (Figure 5) . At the property scale the structural pattern is dominated by an orthogonal set of northwest and northeast trending faults that are interpreted to have originated above the rising Estelle pluton. The northwest faults are interpreted to truncate the earlier northeast fractures but are themselves cut by a later set of northeast trending minor faults. The northwest trending structures are inferred to have an extensional component. At the property scale (Figure 5) , the 2 general structural trends are about 125 and 55 degrees.
Extensive zones of argillic and or phyllic alteration were mapped in the central Oxide deposit area Bundtzsen (2018). The alteration is characterized by a quartz-sericitepyrite assemblage with minor to trace amounts of biotite, kaolinite and potassium feldspar. The alteration is most commonly observed in the Alaskite and in the enveloping quartz monzonite intrusive rocks. Within the altered zones, sulfide mineralization was mapped and sampled.
The sulfide mineralization occurs as:
-
1) Sulfide blebs in within mm-scale sheeted quartz vein arrays;
-
2) Sulfide coatings on joint and fracture surfaces;
-
3) Sulfide blebs within hydrothermally altered quartz-carbonate infillings; and,
-
4) Finely disseminated sulfides in bleached altered intrusive rock.
In hand sample, sulfide minerals include arsenopyrite, pyrite and chalcopyrite. Of these, arsenopyrite is most abundant and occurs as mm-scale grains in veins and pervasively disseminated grains throughout the hydrothermally altered, sugary
Nova Minerals Ltd. Level 17, 500 Collins Street, Melbourne, VIC, 3000. Phone: +61 3 9614 0600 Fax: + 61 3 9614 0550
textured, intrusive host rocks. Sulfide mineralization is most abundant in the Alaskites.
An M.Sc. study completed in 2014 on the Oxide mineralization established the vein assemblages and cross-cutting relationships, identified minerals associated with gold mineralization and determined the relative timing of mineral and vein formation.
Type 1 veins are a quartz-only vein that commonly has sinuous contacts with the host rock. The quartz is typically milky in appearance and is coarse grained (>5 mm). Sparse molybdenite is locally present. Quartz is the only alteration mineral associated with Type 1 veins and silicification adjacent to veins is pervasive.
Type 2 are quartz-sulfide-Au-feldspar veins with albite-sericite alteration selvages and are locally sheeted; Coexisting pyrite, pyrrhotite, and arsenopyrite are the sulfides observed in Type 2 veins. Arsenopyrite contains inclusions of loellingite and/or Au-Bi-Te alloys. Albite is a common alteration mineral associated with the Type 2 veins, and it commonly occurs within the 1 to 30 mm bleached vein selvages. Albite forms rims on igneous orthoclase and plagioclase crystals proximal to the veins forming a “secondary” porphyry-like texture in which the crystals appear larger than their primary size.
Type 3 quartz-sulfide-Au-chlorite veins, which appear to host most of the gold at the Estelle Property, with chlorite-sericite alteration selvages; Type 3 veins are polymetallic with coexisting chalcopyrite, pyrrhotite, and arsenopyrite forming the most common sulfides with lesser galena, argentiferous galena, and bismuthiferous galena occur free in veins and as inclusions in pyrrhotite, chalcopyrite, and arsenopyrite. The most significant gold mineralization occurs as inclusions of gold, bismuth, and tellurium within arsenopyrite. Chlorite is the main alteration mineral associated with Type 3 veins. Chlorite forms 0.2 to 10 cm vein selvages adjacent to Type 3 veins, and is also present within the veins, where it partially or completely replaces biotite. Pyrite is commonly present along chlorite cleavage planes. Sericite and carbonate alteration are also associated with Type 3 veins. Plagioclase adjacent to Type 3 veins has altered to sericite and very fine crystalline calcite is present in the groundmass adjacent to Type 3 veins.
Type 4 veins are calcite-only veins that are typically branching in nature, fine to coarsely crystalline, and iron-oxide stained. Type 4 calcite veins formed last.
Drill Spacing - Based on the above geological interpretation the 2019 RC drilling campaign for the Inferred Resource was planed using a drill spacing of 150 m centers. This is an appropriate spacing for the geometry and footprint of an IRGS style deposit.
Inferred Mineral Resource (Figure 2 and 3) - Supac software using an inversed distance squared interpolation was employed to estimate the Inferred Mineral Resource.
The estimation technique and parameters used are well suited to the data, style of mineralization and the deposit type. The parameters are summarized below: *
-
Interpolation Block Size = 5 m x 5 m x 5 m,
-
Bearing = 0 degrees,
-
Dip = 0 degrees,

-
Plunge = 0 degrees,
-
Minimum Samples = 2,
-
Maximum Samples 15,
-
Cap Grade = No Cap,
-
Search Ellipse Orientation:
-
Azimuth = 0 degrees,
-
Dip = 0 degrees,
-
Plunge = 0 degrees,
-
Anisotropic Search = 140 m for Inferred.
-
Search Ellipse:
-
Semi-Major to Major Axis = 1,
-
Minor to Major Axis = 1,
-
Rotation Type = Surpac ZXY LRL
*** Note** - that the maximum distance that the resource is extrapolated beyond the sample points = 140 m. All of the data is extrapolated using the Inverse Distance Squared Method of interpolation between samples. If the proportions of the blocks that search 140 meters without intersecting another sample are sued then approximately 64 % of the resource tonnes are extrapolated. A shell that outlines the geophysical anomaly that most likely indicates where the gold mineralization exists was used as a cut for any search that would go beyond this shell. However, a 140 m search limit was used even if it did not reach the grade shell boundaries as a conservative measure to limit the Inferred Resource Estimate. Other companies that have conducted resource estimates of on this type of gold deposit in Alaska generally use larger search limits, but a more conservative 140 m search limit was used to limit the tonnes in the Oxide Korbel Resource Estimate. Once more drilling is completed and more data becomes available a full variography study will be completed on the Oxide Korbel deposit
Geological mapping, drill hole data and IP/Chargeability Anomalies were used to create a 3D domain to constrain areas of anomalous mineralization.
Resource Block A trends northwest, measures 700 m 200 m in plan (Figures 1 and 2) and has been projected to a vertical depth of about 585 m. Resource Block A is interpreted to be constrained by parallel bounding faults. The Block B Mineral Resource measures 500 m 500 m in plan (Figures 1 and 2) and has been projected to a maximum depth of about 280 m below surface (Figure 3) . Resource Blocks A and B are interpreted to be part of the same hydrothermal system and likely off-set by the Valley Fault (Figures 1) . Targets C and D (Figure 1) display IP/Chargeability responses very similar to Resource Blocks A and B. Targets C and D have not been drill tested and have not been included in the Oxide Korbel Resource Estimate.
The entire block model is constrained and enveloped by a more extensive 10 mS/S, IP/Chargeability anomaly. The size of the block model was selected to be about the size that average open pit mining equipment would use.
A downhole sample composite size of 2 m was selected based on the average sample size.
A variography study indicates the data is heavily partitioned and the results were considered unsatisfactory. As a result, a maximum spherical search of 140 m for the Inferred category was selected based on the Competent Person’s experience.

In order to evaluate whether cutting or grade capping of higher-grade values is appropriate a decile analysis was performed on the samples above the background of 0.02 g/t Au. This is a quick study of the mean distribution as related to the assay frequency distribution using raw assay data multiplied by sample length. Cutting of high assays should be seriously considered if the top decile has more than 40% of the metal. In this case, the top decile contains about 25% of the metal distribution so no grade capping was conducted.
Depth of Overburden – the first sample in hole SE12-001 (1.83 to 4.24 m) returned a value of 0.243 g/t Au. This value is well above the Inferred Resource Estimate’s lower cut-off grade and demonstrates that mineralization starts at surface in the Oxide Krobel deposit area. The average depth of overburden for the entire drill campaign was 10.0 m.
Cut-off Grades – The Oxide Korbel Resource Estimate was prepared using cut-off grades ranging from 0.5 to 0.50 g/t Au (Table 1) . Similar deposits types to Oxide Korbel include the Fort Knox and Dublin Gulch Eagle deposits which have cut-off grades between 0.10 – 0.15 g/t Au (Table 2) . It is suggested that 0.10 to 0.20 g/t Au is an appropriate cut-off grade to evaluate the future economics of this project.
Bulk density – Based on mapping data collected by Pacific Rim Geological Consulting in 2018 the main host rock type for the mineralization at Oxide Korbel consists dominantly of granite. Most of the rock types in the Oxide Korbel map area (Figure 1 ) plot in the granite Field on Normative QAPF diagram Plot (Figure 4) . Alteration that is overprinting the granites in the Oxide Korbel deposit area is minimal and has limited effect on the bulk density. There is no significant oxide mineralization present at this deposit. The Inferred Resource estimate falls 100% within the sulphide domain and is represented by fresh rocks only. The average bulk density of granite is between 2.65 and 2.75 g/cm[3] . A density of 2.68 g/cm[3] was selected for the Oxide Korbel Resource estimate, as no density data of the hosting granite is available. This estimate for dry bulk density compares favourably for that used in similar deposits types such as Fort Knox and Dublin Gulch (Table 2) .

Sample Collection and Analytical Techniques - The drilling during the 2018 and 2019 campaign consisted of Reverse Circulation drilling, or RC drilling. This is a method of drilling which uses dual wall drill rods that consist of an outer drill rod with an inner tube. These hollow inner tubes allow the drill cuttings to be transported back to the surface in a continuous, steady flow.
For 2018 and 2019 RC drilling each 1.52 m interval sample run was riffle split to

obtain a 4 - 6 kg sample, which were sent to ALS laboratory in Fairbanks for pulverization to produce a 250 g sub-sample for analysis. For RC drilling each 4 – 6 kg sample that was sent to ALS Fairbanks and an off cut of chips were generated and provided to Pacific Rim Geological Consulting for detailed chip logging. RC data was logged digitally into Excel templates and validated. Remaining half cores from historical drill holes (2011 to 2012) were sampled at ~3.05 m intervals. Samples were sent to ALS laboratory in Fairbanks for pulverization to produce a 250 g subsample for analysis. Sample prep consisted of ALS Prep 31 - Crush to 70% less than 2 mm, riffle split off 250 g, pulverize split to better than 85% passing 75 microns. Sample analysis consisted of ALS Au-ICP21 Fire Assay with 30 g sample charge using ICP-AES finish. Detection Limits range from 0.001 - 10 g/t Au. For sample exceeding the upper detection limit of 10 g/t Au the material was re-run using ALS method Au-GRA21. This Fire Assay technique utilizes a charge size of 30 g and a gravimetric finish. Detection Limits range from 0.05 -10,000 g/t Au.

Internal prioritised systematic exploration strategy
The Company’s ranked and prioritised systematic exploration strategy and activities at Estelle are guided by an exploration “Project Pipeline” process to maximise the probability of multiple major discoveries ( Table 3 ). Each Milestone is defined by a specific deliverable and has each criteria needs to be ticked to determine which prospect must pass through before moving to the next Milestone. Economic criteria and probability of success increase as projects move along the pipeline (Figure 4) . The methodology helps to ensure work is carried out across all stages of the process, cost are kept minimal and that focus is kept on the best quality targets and that the pipeline is kept full with early Milestone projects.
