The company is fundamentally running on schedule to unlock the Estelle Gold Project, which sits within the much larger Estelle Gold Trend, in a Tier 1, safe jurisdiction
Nova CEO, Mr Christopher Gerteisen commented: “Unlocking the Estelle gold district and discovering new opportunities in one of the most favourable mining jurisdictions in the world was a key milestone Nova achieved in 2022. With full credit to our field crew and team, we are actively building a pipeline of deposits to continue to increase the life of mine, with more potential discoveries on the horizon.
The RPM deposit continues to be the jewel in the crown with 340 koz @ 2.3 g/t Au Measured and Indicated resources ( including a super high-grade Measured component of 180 koz @ 4.1 g/t Au ) now defined at RPM North, which remains open in several directions. This broad and continuous high-grade zone at surface will be the initial focus of any future mining scenario, potentially generating value for the company through project return and a reduced payback period. As is, this zone already constitutes one of the largest high-grade undeveloped open pit gold deposits from surface. However, with the geological observations to date and the 2023 drilling program to commence shortly, real potential exists for the starter pit at RPM to yield a much higher gold resource.
While the current MRE interpretation has taken a very conservative approach, in terms of model parameters and resource classification by a new independent geologist, which conforms with the Reasonable Prospects for Eventual Economic Extraction (RPEEE) principles, the global MRE update nonetheless provides an improved platform for the upcoming Phase 2 Scoping Study which aims to improve the overall economic metrics, annual gold production rate, and mine life across the Estelle Gold Project relative to the February 2022 Phase 1 Scoping Study of 1.9 Moz over 15 years.
PFS level trade-off studies have also continued in parallel, and these studies, along with further potential increases in Measured and Indicated resources from the planned 2023 drill campaign at RPM and in the highly prospective Train area, which will also be incorporated in to the PFS, are expected to provide a strong basis for project development and financing.
With long-term opportunity and the prospect of multiple mining complexes across the single project, we continue on our path to becoming a world class, tier 1 global gold producer.”
Nova Minerals Limited ( Nova or the Company ) ( ASX: NVA, OTC: NVAAF, FSE: QM3 ) is pleased to announce an independent global JORC Resource (‘the Resource’) of 9.9 Moz of gold has been estimated at the Estelle Gold Project. The Resource, which is based on the assay results from ~ 85,000m of RC and high quality oriented diamond core drilling completed up to 9 March 2023, starts from surface, and is on less than 3% of the total project area.

Diamond drilling over the last 12 months has delivered on four key aspects:
-
Extending the open pit mining potential at RPM and Korbel
-
Identifying a sizable high-grade M&I core at surface at RPM North suitable for early mining
-
• Infill drilling to convert further Inferred to Indicated and Measured Resources
-
Geotechnical, metallurgical, and hydrology drilling to enable the PFS economic and environmental studies to advance
The current MRE is based on tighter spaced infill drilling with the new independent geologist mandated to take a relatively conservative approach in terms of model parameters and resource classification to demonstrate that all of the resource being reported accords with the prospects for eventual economic extraction (RPEEE) principles as the company now advances into Phase 2 Scoping Study, and upon its completion the PFS.
All deposits remain open with significant potential upside and with almost 24 hours of daylight in Alaska in the coming months Nova plans to operate multiple diamond rigs drilling on site 24 hours 7 days a week, with PFS stage drilling focusing on both increasing the drill density of the resource, plus extensional drilling to further grow the resource.
While the exploration focus over the next 12 months will pivot to resource growth at the RPM Mining Complex along strike and at down dip extensions at RPM, and the high priority untested targets within the Train area prospects, it is however important to also note that a high-grade mineralized zone also sits within the Korbel resource.

Resource Modelling
General
Resources were estimated for the Korbel Main, Cathedral and RPM North and South deposits by Multiple Indicator Kriging with block support correction to reflect open pit mining selectivity, a method that has been demonstrated to provide reliable estimates of resources recoverable by open pit mining for a wide range of mineralisation styles.
The estimates are based on information from RC and diamond drilling data supplied by Nova in February and March 2023 and are reported below a triangulation representing natural surface provided by Nova. Nova specified that Matrix were not required to review the reliability of the supplied information, or consider the potential for economic extraction of the estimates, with Nova nominating Competent Persons to take responsibility for these aspects of the estimates. With the exception of modifying comparatively few erratic down-hole survey entries and some adjustments to give drill hole collars more consistent with the supplied topographic triangulation, Matrix used the sampling data on an as-supplied basis.
Micromine software was used for data compilation, domain wire framing and coding of composite values and GS3M was used for resource estimation. The resulting estimates were imported into Micromine for resource reporting. The estimation methodology is appropriate for the mineralisation style.
The MIK modelling is based on 3.048 metre (10 foot) down-hole composited gold grades from RC and diamond drilling. The selected composite length represents the dominant sample length. Modelling of each deposit area incorporated a generally low gold grade background domain and between one and three mineralised domains interpreted by Matrix which capture composites with gold grades of generally greater than 0.1 g/t and delineate zones within which the tenor and spatial trends of mineralisation are similar.
For each deposit, grade continuity was characterised by indicator variograms modelled at 14 indicator thresholds. For determination of variance adjustment factors a variogram was modelled from composite gold grades. The modelled variograms are consistent with geological interpretations and trends shown by composite gold grades.
Class grades used for MIK modelling were derived from class mean grades with the exception of upper bin grades which were generally derived from the class median, class mean excluding a small number of outlier composites or rarely the bin threshold grade.
For each deposit area, the MIK modelling utilised between and three and six progressively relaxed search passes which were selected on the basis of the drill hole spacing and mineralisation trends to inform a reasonably large proportion the mineralised domains while allowing blocks to be estimated by reasonably close data where possible.
The estimates include a variance adjustment to give estimates of recoverable resources above gold cut-off grades for comparatively large scale open pit mining with selectivity of around 10 by 10 by 5 metres for Korbel and Cathedral and around 5 by 10 by 5 metres for the RPM North and South deposits. The Mineral Resource estimates can be reasonably expected to provide appropriately reliable estimates of potential mining outcomes at the assumed selectivity without application of additional mining dilution or mining recovery factors.
The estimates include densities of 2.65 tonnes per bank cubic metre (t/bcm) reflecting the average of calliper density measurements undertaken by Nova on diamond drill core.

Korbel Mining Complex
Korbel Main Modelling
Modelling of the Korbel Main deposit includes a main, northwest trending, sub-vertical mineralised domain and two subsidiary mineralised domains designated as Block C and Block D respectively (Figure xx). The Main zone domain trends northwest over around 2.6 kilometres with an average width of around 370 metres. The Block C and D domains have extents of around 140 by 180 and 400 by 370 metres respectively. The modelling also included a surface representing the base of unmineralized overburden interpreted from drill hole geological logging which averages around 7 meters thick.
The estimation dataset comprises 20,126 composites with gold grades ranging from 0.001 g/t to 14.1 g/t and averaging 0.19 g/t.
The block model, which is rotated 40o from north south, aligning model axes with the mineralised trends and drill traverses, comprises panels with dimensions of 50 by 50 by 10 metres One set of indicator variograms modelled from the main domain composites was used for the modelling.
Estimates for mineralisation tested by drilling spaced at around 100 metres, including more some more broadly sampled areas to give a consistent distribution are classified as Indicated. Estimates for more broadly sampled mineralization, extrapolated up to around 120 meters from general drilling areas are classified as Inferred. The estimates extend to around 820 meters depth with around 80% from depths of less than 500 meters.

Cathedral Modelling
Modelling of the deposit utilised two steeply west dipping mineralised domains designated as the West and East Domains respectively. The West Domain, which contributes the majority of estimated resources is interpreted over around 780 metres of strike with an average horizontal width of around 340 metres. The East domain, which captures comparatively low average drill hole gold grades trends over around 420 metres of strike with an average width of around 110 metres.
The block model used for MIK modelling comprises 50 by 100 by 40 metre panels. The estimation dataset comprises 1,345 composites with gold grades ranging from 0.00 to 2.72 g/t and averaging 0.21 g/t.
Cathedral drilling includes too few regularly gridded drill holes for reliable variogram modelling and variogram models used for MIK modelling were derived from those used for the Korbel estimates rotated to reflect interpreted Cathedral mineralization trends.
The estimates include a bulk density of 2.65 t/bcm, which is consistent with the density applied to estimates for the Korbel deposit.
All estimates for Cathedral are classified as Inferred reflecting the comparatively broad and irregularly spaced drilling. The estimates are reported below the supplied topographic wire-frame and are extrapolated to generally around 120 metres along strike and below drill holes. Estimated panels extend above drill holes to surface, on the basis of rock chips and geological observations of surface exposures reported by Nova, both of which show mineralisation at surface. The estimates extend from surface to around 500 metres depth with around 90% from depths of less than 380 metres.

RPM Mining Complex
RPM North Modelling
RPM North modelling utilized three, subvertical east-west trending mineralised domains (Figure 5) comprising a subsidiary southern domain of comparatively lower gold grades, and a northern domain with an internal core of notably higher composite gold grades.
The northern zone is interpreted over around 550 metres of strike with an average width of around 75 metres, encompassing the high grade core domain which comprises an ovoid shaped zone around 130 by 60 metres in plan extending to around 250 metres depth. The southern domain trends over around 600 metres of strike averaging approximately 120 meters thick.
Nova Minerals Ltd | ASX Announcement

==> picture [71 x 45] intentionally omitted <==
The available drilling comprises 30 fan holes from three drill pads, including 21 from the eastern most pad, giving locally closely spaced drilling within the high grade core domain. The drilling provides an estimation dataset of 3,336 composites with gold grades ranging from 0.0004 to 79.15 g/t and averaging 0.82 g/t.
One set of indicator variograms modelled from the combined northern domain composites was used for the modelling. The block model comprises 20 by 20 by 10 metre panels reflecting the drill spacing for closely drilled portions of the deposit.
The estimates include a bulk density of 2.65 t/bcm, which is consistent with the density applied to estimates for the Korbel deposit.
Estimates for the RPM North deposit area classified as Measured, Indicated and Inferred utilising a set of plan-view polygons outlining areas of relatively consistent drill spacing. These polygons classify estimates tested by drilling spaced to around 25 metres and 50 metres respectively as Measured and Indicated, and estimates for more broadly sampled mineralisation extrapolated to around 120 metres from drilling as Inferred.
Model estimates extend to around 360 metres depth with around 90% from vertical depths of less than 280 metres.

RPM South Modelling
Modelling of the RPM South deposit utilised a steeply southerly dipping mineralised domain interpreted over around 360 metres of strike with an average width of around 170 metres. The available drilling which comprises eight fan holes from a single drill pad provides 870 composites with gold grades ranging from 0.003 to 6.26 g/t and averaging 0.40 g/t. There is too few data for reliable variogram modelling and variograms modelled for RPM North were used for the RPM South estimation.
The MIK modelling utilised 60 by 30 by 15 metre panels and four progressively relaxed search passes. The estimates include a bulk density of 2.65 t/bcm, which is consistent with the density applied to estimates for the Korbel deposit.
All estimates for RPM South are classified as Inferred reflecting the comparatively broad and irregularly spaced drilling. The estimates are reported below the supplied topographic wire-frame and are extrapolated to generally around 120 from drilling. The mineralisation cross cuts a prominent northerly trending ridge, and outcrops at between 1,775 mRL on the western flank of the ridge to around 1,960 mRL around the ridge crest. Model estimates extend to around 400 metres depth with around 90% from depths of less than 250 meters.

Unlocking Multiple Potential Mining Centers
The significant scope for major resource development across the Estelle Gold Project, with four mineral resource deposits already identified, and possibly another deposit in the Train area as well (subject to drilling to commence in 2023), has now given the company optionality to investigate the case for potentially developing two standalone mining operations within the single project – A northern mining center around the Korbel Mining Complex and a southern mining center around the RPM Mining Complex (Figure 12).
Upon the completion of Phase 2 Scoping Study, PFS level trade off studies will be used to investigate the possibility of establishing an initial standalone processing plant within the RPM Mining Complex, for the initial years, with another processing plant within the Korbel Mining Complex to be commissioned in later years, as outlined in the previously released Phase 1 Scoping Study (ASX Announcement 28 February 2022).
West Susitna Access Road Progresses to Permitting
An independent economic study prepared for the Alaska Industrial Development and Export Authority (AIDEA), and fully supported by the Alaska State Governor, recommends the West Sustina Access Road begins the permitting process with construction proposed to start in 2025.

==> picture [71 x 45] intentionally omitted <==
AIDEA has submitted the CWA 404 permit application to the USACE for the West Susitna Access project, initiating the environmental review process through compliance with the National Environmental Policy Act. Field studies will begin this summer with further evaluation of cultural and historical sites, fish and wildlife habitat, engineering refinement, and alternative route analysis. (Figure 11).
Alaska Governor, Mike Dunleavy, who fully supports the roads construction said “The West Susitna Road is important for local residents and gaining fair access to hunting, fishing, and potential jobs.
My administration is constantly looking at ways to grow our economy and this project is a great opportunity for not only south-central Alaska but the entire state. I am committed to this project and unlocking resources that benefit all Alaskans.“
Construction of the road will scientifically decrease the capital and operating cost of a future mine at Estelle thereby allowing the Mineral Resource cut-off grade to be lowered to the Fort Knox and Dublin Gulch cut-off level.

Appendix 1: Project Technical Information
The property is situated within the Koyukuk terrane, one of several arc assemblages accreted late into the North American Cordillera. The 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 (ASX Announcement 19 June 2019)
A satellite image study of the entire Estelle property was completed by Michael Baker in 2019. 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, the 2 general structural trends are about 125 and 55 degrees. Extensive zones of argillic and or phyllic alteration were mapped in the central deposit area
Bundtzsen (2018). The alteration is characterised by a quartz-sericite-pyrite 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 mineralisation occurs as:
-
Sulfide blebs in within mm-scale sheeted quartz vein arrays;
-
Sulfide coatings on joint and fracture surfaces;
-
Sulfide blebs within hydrothermally altered quartz-carbonate infillings; and,
-
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 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. 8 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 AuBi-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.
Density Measurements
Bulk density - The average density of 2.65 g/cm[3] was selected for this estimate. This estimate for dry bulk density compares favourably for that used in similar deposit types such as Fort Knox, Dublin Gulch and the nearby Korbel.
Pulp sample method: Density of competent rocks that have very low porosity and low natural water content may be measured using a gas pycnometer and rock pulp samples (finely milled rock) but this method is not suitable for porous rocks, as the fabric is destroyed by the milling process. The gas pycnometer method determines volume within the sample chamber from which an inert gas is excluded. The pycnometer gives volumes for samples weighed into plastic vials (Figure 3), which are in turn dropped into the sample chamber. Best precision is obtained from the largest possible volume of sample which is typically around 30 grams. Pulps samples were measured by ALS using method OA-GRA08b.

Sample Collection and Analytical Techniques
Diamond Drilling sampling is completed on sawing half HQ core. Sampling is based along lithological contacts and is sampled at 3.05 meter (10 ft.) intervals (run block to run block). Core was sampled at 3.05 m intervals. Samples were sent to ALS laboratory in Fairbanks for pulverization to produce a 250 g sub-sample for Au analysis.
Whole HQ core is logged in a qualitatively and quantitatively manner and recorded into a running Excel spreadsheet.
The following data was collected:
-
Major units and samples follow lithological changes.
-
Primary, secondary, and tertiary alteration types and intensity
-
Mineralization type (arsenopyrite, pyrite, and chalcopyrite), percentage mineralization, and texture Structures including veins, faults, and shears. Orientation recorded (alpha/beta).
-
Prep or reject duplicates were collected every 1 in 20 samples.

Blank material was inserted 1 in 40 samples and consist of Pea Gravel obtained from Alaska Industrial Hardware. Certified Reference Material (CRM) was inserted 1 in 20 samples. Three different CRMs at three different grades levels were used. Prep or reject duplicates were collected every 1 in 20 samples. Acceptable levels of precision and accuracy were obtained.
Samples were sent to the 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.

Appendix 2: JORC Code, 2012 Edition – Table 1 Estelle Gold Project - Alaska
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, whether core is oriented and if so, by what method, etc.). |
• HQ diamond core triple tube, down hole surveys every 150 feet (~50m), using a Reflex ACT-III tool. |

| Criteria | **JORC Code Explanation ** | Commentary |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material |
• Core is processed at the on- site certified crush/split prep- lab with ~250g sample being sent of site to the ALS analytical lab in Reno Nevada. Recoveries were recorded for all holes, into a logging database to 3cm on a laptop computer by a qualified geologist using the drillers recorded depth against the length of core recovered. No significant core loss was observed. • Triple tube HQ to maximise core recovery and enable orientation of core. • No known relationship between sample recovery and grade. As no samples have been taken as yet, no assay results are reported, visual results only. |
| Logging | • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. • The total length and percentage of the relevant intersections logged. |
Core logging is carried out by qualified geologists using a project specific logging procedure. Data recorded includes, but is not limited to, lithology, structure, RQD, recovery, alteration, sulphide mineralogy and presence of visible gold. This is supervised by senior geologists familiar with the mineralisation style and nature. Inspection of the drill core by the site Chief Geologist is monitored remotely using photographs and logs. Rock codes have been set up specifically for the project. Logging is to a sufficient level of detail to support appropriate Mineral Resource estimation and mining studies. • Drill logging is both qualitative by geological features and quantitative by geotechnical parameters in nature. Photographs are taken |

| of all cores trays, (wet) of whole coreprior to cutting. |
||
| Sub- sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
• Samples are taken each 10 feet (3.05m) unless there is a change in lithology. 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. Three different types of SRM are inserted each 20 samples. Duplicates of the reject are taken each 20 samples. One blank is inserted each 40 samples. Data is plotted and evaluated to see if the samples plot within accepted tolerance. If any “out of control” samples are note, the laboratory is notified. |
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
• Samples are tested for gold using ALS Fire Assay Au- ICP21 technique. This technique has a lower detection limit of 0.001 g/t with an upper detection limit of 10 g/t. If samples have grades in excess of 10 g/t then Au-AA25 is used to determine the over detect limit. Au-AA25 has a detection limit of 0.01 g/t and an upper limit of 100 g/t. Three different types of SRM are inserted each 20 samples. Duplicates of the reject are taken each 20 samples. One blank is inserted each 40 samples. Data is plotted and evaluated to see if the samples plot within accepted tolerance. If any “out of control” samples are note, the laboratory is notified. |

| Drill hole Information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: - easting and northing of the drill hole collar - elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar - dip and azimuth of the hole - down hole length and interception depth -hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
• See Table 3 summary table of drill hole results. |
| 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 brokenoutifpresent. |

| Estimation and modelling techniques |
• The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by-products. • Estimation of deleterious elements or other non-grade variables of economic significance (eg sulphur for acid mine drainage characterisation). • In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed. • Any assumptions behind modelling of selective mining units. • Any assumptions about correlation between variables. • Description of how the geological interpretation was used to control the resource estimates. • Discussion of basis for using or not using grade cutting or capping. • The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available. |
•Resources were estimated for the Korbel Main, Cathedral and RPM deposits by Multiple Indicator Kriging with block support correction to reflect open pit mining selectivity, a method that has been demonstrated to provide reliable estimates of resources recoverable by open pit mining for a wide range of mineralisation styles. The modelling technique is appropriate for the mineralisation style, and potential mining method. •The MIK modelling is based on 3.048 m (10 foot) down- hole composited gold grades from RC and diamond drilling. The selected composite length represents the dominant sample length. •Micromine software was used for data compilation, domain wire framing and coding of composite values and GS3M was used for resource estimation. The resulting estimates were imported into Micromine for resource reporting. •Grade continuity was characterised by indicator variograms modelled at 14 indicator thresholds. Class grades were derived from class mean grades with the exception of upper bin grades which were generally derived from the class median, class mean excluding a small number of outlier composites, or rarely the bin threshold grade. This approach reduces the impact of small numbers of extreme gold grades on estimated resources and in the Competent Person’s |

| Moisture | • Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content. |
All tonnages are estimated on a dry basis. |
| Cut-off parameters |
• The basis of the adopted cut-off grade(s) or quality parameters applied. |
The cut-off grades selected for resource reporting reflect Nova’s interpretation of potential project economics. The Mineral Resource has been reported at a 0.15 for Korbel and 0.2 g/t Au grade cut-off for the RPM deposit. This cut-off was chosen using current economic parameters applicable for open cut mining for similar deposit types. Similar deposits to Estelle include the Fort Knox and Dublin Gulch Eagle deposits which have cut-off grades between 0.10 – 0.5 g/t Au. Note: With positive results from Ore-Sorting testing at TOMRA Nova is now confident in dropping the Cut-Off Grade from 0.18 (historic) to 0.15 g/t and reasonable prospects of eventual economic extraction at deeper depths left in inferred and util;ising other mining methods. |
| Mining factors or assumptions |
• Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made. |
•Estimates for the Korbel Main and Cathedral deposits include a variance adjustment to give estimates of recoverable resources above gold cut-off grades for open pit mining with selectivity of around 10 by 10 by 5 m with grade control sampling on a 10 by 20 by 3.0 m pattern. •Estimates for the RPM North and South deposits include a variance adjustment to give estimates of recoverable resources above gold cut-off grades for open pit mining with selectivity of around 10 by 5 by 5 m with grade control sampling on a 10 by |

| 8 by 3.0 m pattern. The only mining method envisaged over 20 year mine life for the extraction of gold from Korbal, Cathderal and RPM North and South deposit is anticipated to involve large- scale open pit, truck and shovel mining methods. Grade control of mining blocks will be based on sampling from high quality reverse circulation grade control drilling holes. Block cave mining method is envisaged for the later years. |

| Metallurgical factors or assumptions |
• The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made. |
• Extensive test work has shown that gold resources within the RPM and Korbel deposits can be liberated and economically recovered utilizing conventional technology. A robust process flow sheet has been developed through test work whereby crushing-milling- gravity-flotation-leaching are employed. >95% recovery has been achieved through the flotation test work. >96% recovery has been achieved from leach test work. • Lower grade portions of the resources have been shown to be amenable to ore sorting through extensive test work at TOMRA. Grade control through ore sorting improves the economic viability of lower grade resources by upgrading ore and rejecting waste. The results of test work have shown the ability to ore sort 0.3 g/t Au material and upgrade up to 6 g/t Au with the optimal upgrade lying somewhereinbetween |

| Environmental factors or assumptions |
• Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made. |
•Economic evaluation of the project is at an early stage. It is assumed that development of the Estelle project would include construction of camp, milling, processing, waste rock and tailings disposal facilities constructed. Power and road access would also likely be required. Processing operations may utilise a dry stacked tailings storage facility which combines a waste landform with filtered tailings in a lined facility and subsequently covered by mine waste material. Subaqueous settlement beneath a pit lake (water cover) may be used to prevent the oxidation of tailings. |
| Bulk density | • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluation process of _the different materials. _ |
•Bulk were densities assigned to the estimates on the basis of caliper measurements of drill core, including 105 from Cathedral, 1,359 Korbel and RPM |

Estimates for more broadly sampled mineralisation, extrapolated up to around 120 m from general drilling areas are classified as Inferred. •All Cathedral resource estimates are classified as Inferred reflecting the comparatively broad and irregularly spaced drilling. The estimates are extrapolated to generally around 120 m along strike and below drill holes. Estimated panels extend above drill holes to surface, on the basis of rock chips and geological observations of surface exposures reported by Nova, which show mineralisation extending to surface. •Estimates for the RPM North deposit area classified as Measured Indicated and Inferred utilising a set of plan-view polygons outlining areas of relatively consistent drill spacing. These polygons classify estimates tested by drilling spaced to around 25 m and 50 m respectively as Measured and Indicated, and estimates for more broadly sampled mineralisation extrapolated to around 120 m from drilling as Inferred. •All RPM South estimates are classified as Inferred reflecting the comparatively broad and irregularly spaced drilling. The estimates are extrapolated to a maximum of generally around 120 m from drilling. |

For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could affect the relative accuracy and confidence of the estimate. • The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation. Documentation should include assumptions made and the procedures used. • These statements of relative accuracy and confidence of the estimate should be compared with production data, where _available. _ |
