Table 1. Lucky Draw and Hackney’s Creek Mineral Resources by model and resource category
The Lucky Draw and Hackney’s Creek deposits occur along strike from each other about 1km apart and 5km northeast of the village of Burraga.
Geology and Geological Interpretation
The Lucky Draw and Hackneys Creek gold deposits occur in metasomatised sediments of the Ordovician Triangle Formation immediately below the contact with mafic volcanic rocks inferred to belong to the Rockley Volcanics and very close to the contact with the Carboniferous Burraga Granite. The skarn-like ore displays a gold – bismuth - tellurium association (an “intrusion-related gold” signature) but is generally sulphur-poor with a very low sulphide mineral content. Skarn-like mineral assemblages (including garnet and gedrite), alteration and mineralisation at Lucky Draw including are considered by Sheppard et al . (1995) to be the product of contact metamorphism and hydrothermal activity associated with the intrusion of the Burraga Granite.

Weathering and associated oxidation of sulphide minerals extends to about 30m below surface.
The Lucky Draw deposit comprises multiple 2 m to 15m thick zones within an overall package about 70 m thick. Both the individual zones and the package strike north south and dips gently (20° - 30°) to the west. Gold mineralisation at Lucky Draw has been defined by drilling over a strike length of 400 m and 200 m down dip to a depth of about 100 m below surface.
At Hackney’s Creek gold mineralisation also occurs in multiple 2 m to 20m thick zones within an overall package about 120 m thick. Mineralisation also strikes north and dips 50° to 60° to the west. Drilling has defined gold mineralisation over a strike length of 220 m and 250 m down dip to about 250 m below surface.
Sampling and Sub Sampling Techniques
DD core was cut using a diamond core saw and half core sub-sampled. The procedure was to take DD core samples geological contacts to a maximum of 1.0 m.
The RC sub-sampling method was not recorded.
The trenches were logged and sampled at 2.5 intervals.
Drilling Techniques
These resources have been estimated from trenching, reverse circulation (RC) drilling and diamond drilling (DD) carried out by Renison Goldfields (RGC) from 1986 until 1993 and by Werrie Gold in 1999 as described in the table below.

Table 2 Drilling data used in resource estimates by company and drilling method
DD drilling (including holes with RC pre-collars) comprises 78.1 % of Lucky Draw and 38.2% of Hackney’s Creek data. All DD drilling used a triple tube core barrel which maximises core recovery. The hole size data has only been located for 19% of the Lucky Draw and 54% of the Hackney’s Creek DD drilling. At Lucky Draw where hole size was recorded, 62% of the DD drilling was HQ, 10% “HQNQ” and 28% PQ. At Hackney’s Creek the recorded DD hole sizes were 58% HQ and 42% NQ.
RC drilling was not well described. The hole diameter was 4.5 inches. When dry sample could not be maintained the hole was stopped and finished with a DD tail. There is no information on the hammer type, rod size or compressor capacity.
Surface Ditchwitch trenches at Hackney’s Creek were dug to about 1 m depth. The trench locations were surveyed by tape and compass from grid pegs.
Criteria Used for Classification
All resources reported were classified as inferred.
The Lucky Draw resource estimate was classified largely taking into account the limited data available to assess sample quality and also the limited understanding of the geological controls on gold mineralisation. The drill spacing is very close in places and so a small amount of additional drilling has the potential to re-classify some of the resources as measured or indicated if the data quality can be demonstrated.
The current drill spacing at Hackney’s Creek is quite wide relative to the variogram model ranges and so further infill drilling will be required to upgrade the deposit to Indicated and Measured resources categories.
Sample Analysis Method
All samples were dried, crushed, milled to 150um, a 500g riffle split taken and further milled to 100um. A 50g charge was then assayed for Au by fire assay with AAS finish. The lower detection limit was 0.01 g/t.
Estimation Methodology
Lucky Draw Resource Estimation
The data was domained using a wireframe interpreted at a nominal 0.2 g/t Au.
A regularised block model was constructed using blocks of 10 m by 10 m by 2.5 m (XYZ). This model was in turn coded for proportions of blocks below / inside the topography and inside the gold grade domain.
The maximum extrapolation at Lucky Draw was 22.5m and at Hackney’s Creek 25m. In both deposits this was half the section spacing. With the resource estimation software package used it is not possible to calculate (or even define) the proportion of extrapolated resource. A visual estimate is that no more than 10 % of the resource estimates are based on extrapolated grades.
All raw assay samples were composited to 2.5 metres prior to statistical analysis and grade interpolation.
The Lucky Draw resource was estimated by ordinary kriging of composited gold grades cut to 25 g/t Au within the gold grade domain as a hard boundary. No other elements were estimated due to a lack of data.
An assumed bulk density of 2.6 t/m[3] was assigned globally because there was no density data available at the time the resource estimate was made. The bulk density value was based on a typical bulk density of the mineralisation host rock (predominantly unweathered garnet schist).
The Lucky Draw resources were reported from below both a wireframe of the final mine survey and a topographic surface constructed by triangulating pre-mining drill collars.
The block model was validated visually and against alternative interpolation methods. The resource estimate was also reconciled to the Lucky Draw open pit production data.
Hackney’s Creek Resource Estimation
The Hackney’s Creek resource estimate largely followed the methods used at Lucky Draw, however no top cut was applied as there was no statistical evidence that is was necessary.
Cut Off Grade
The Mineral Resource cut-off grade for reporting of global gold resources for the Lucky Draw and Hackney’s Creek deposit chosen as 0.5g/t gold for open cut mining. This was based upon economic parameters utilised at comparable projects where deposits of the same style, commodity, similar size and mining methodology are currently being extracted.
Mining and Metallurgical Methods and Parameters
Open pit mining is assumed based on the width and near surface location of the mineralisation. Current gold prices would likely result in a significantly deeper optimal pit at Lucky Draw than the pit design mined by RGC during the early 1990’s.
High metallurgical recovery (>90%) is assumed at Lucky Draw based on the successful operation of the Lucky Draw gold processing plant (conventional crushing and milling followed by CIP leach and electrowinning).
Preliminary metallurgical test work was carried out on 3 samples of ore from the Hackney’s Creek Deposit by RGC NSW Ltd, showing a work index ranging from 7.4-8.0 kWh/t and a potential gold extraction of 89-95% in a 24 hour cyanide leach. These results compared favourably to the Lucky Draw ore, with slightly higher recoveries potentially indicated.

Report on an Estimate of Gold Mineral Resources at Hackneys Creek and Luck Draw.
16 April, 2020.

1 Summary
An estimate was made of gold mineral resources at the Lucky Draw and Hackney’s Creek deposits for Elysium Resources Ltd (EYM) in 2011. Following a re-structure EYM has changed name to Paterson Resources Ltd (PSL). This report describes the 2011 resource estimate.
The Lucky Draw and Hackney’s Creek deposits occur along strike from each other about 1km apart and 5km northeast of the village of Burraga.
The Lucky Draw and Hackneys Creek gold deposits occur in metasomatised sediments of the Ordovician Triangle Formation immediately below the contact with mafic volcanic rocks inferred to belong to the Rockley Volcanics and very close to the contact with the Carboniferous Burraga Granite. The skarn-like ore displays a gold – bismuth - tellurium association (an “intrusion-related gold” signature) but is generally sulphur-poor with a very low sulphide mineral content. Skarn-like mineral assemblages (including garnet and gedrite), alteration and mineralisation at Lucky Draw including are considered by Sheppard et al . (1995) to be the product of contact metamorphism and hydrothermal activity associated with the intrusion of the Burraga Granite.
Weathering and associated oxidation of sulphide minerals extends to about 30m below surface.
These resources have been estimated from trenching, reverse circulation drilling and diamond drilling carried out by Renison Goldfields (RGC) from 1986 until 1993.
There is limited data describing the drilling, sampling and assaying methods used in these resource estimates. There is almost no QAQC data to confirm the quality of these data. All the mineral resources reported here are classified as inferred because of the uncertainty regarding the data quality into account
RGC mined an open pit at Lucky Draw from December 1988 until 1991, producing 1.48 million tonnes grading 3.53 g/t gold.
1.1. Lucky Draw Resource Estimation
The data was domained using a wireframe interpreted at a nominal 0.2 g/t Au.
A regularised block model was constructed using blocks of 10 m by 10 m by 2.5 m (XYZ). This model was in turn coded for proportions of blocks below / inside the topography and inside the gold grade domain,
All raw assay samples were composited to 2.5 metres prior to statistical analysis and grade interpolation.
The Lucky Draw resource was estimated by ordinary kriging of composited gold grades cut to 25 g/t Au within the gold grade domain as a hard boundary. No other elements were estimated due to a lack of data.
An assumed bulk density of 2.6 t/m[3] was assigned globally because there was no density data available at the time the resource estimate was made. The bulk density value was based on a typical bulk density of the mineralisation host rock (predominantly un-weathered garnet schist).
The Lucky Draw resources were reported from below both a wireframe of the final mine survey and a topographic surface constructed by triangulating pre-mining drill collars.
The block model was classified in accordance with the JORC (2012) code largely taking into account the limited data available to assess sample quality and also the limited understanding of the geological controls on gold mineralisation. The drill spacing is very close in places and so if the data quality can be demonstrated and the geology well understood then it could be possible to re-classify some of the resources as measured or indicated.
The block model was validated visually and against alternative interpolation methods. The resource estimate was also reconciled to the Lucky Draw open pit production data.

1.2. Hackney’s Creek Resource Estimation
The Hackney’s Creek resource estimate largely followed the methods used at Lucky Draw.
The only significant difference in method is that no top cut was applied as there was no statistical evidence that a top cut may be necessary.
The current drill spacing at Hackney’s Creek is quite wide relative to the variogram model ranges and so there is no possibility of indicated resources without infill drilling as well as demonstrating the data quality and developing a sound understanding of the geology.
1.3. Results
The Lucky Draw and Hackney’s Creek mineral resources are presented in Table 1.
The gold resources are reported at a cutoff of 0.5 g/t Au.

2.2. Context
This resource estimate will be used for public reporting of mineral resources by Paterson Resources Limited (PSL).
The mineral resource estimates reported on here were completed by GML in 2011 for Burraga Copper Ltd, at that time controlled by Elysium Resources Ltd. (EYM). This work was not publicly announced at the time and so no supporting report describing the resource estimation processes was made at the time. This report describes the work completed in 2011 and is intended to support the public reporting of the gold mineral resource estimates at Lucky Draw and Hackney’s Creek by PSL.
2.3. Tenement
The Lucky Draw and Hackney’s Creek deposits are located within EL6463, held by BC Exploration Propriety Limited (BCEL). BCEL is a 100% owned subsidiary of PSL.
2.4. Other
2.4.1. Software
All the geological and block modelling was completed using Minesight software.
Statistical and geostatistical analysis was completed using Minesight MSDA software.

3 Geology
3.1. Regional Geology
The recent discovery of substantial gold mineralisation at McPhillamys Hill between Blayney and Bathurst has altered the perspective of key structural controls on gold mineralisation and the prospectivity of sections of the Lachlan Fold Belt. The McPhillamys deposit (2.3 million ounces gold resource) lies on the southwestern margin of the Hill End Trough adjacent to the Godolphin Fault within strongly deformed sediments and acid volcanics (Anson Formation) belonging to the Late Silurian Mumbil Group. The Godolphin Fault separates the Mumbil Group rocks that host the McPhillamys deposit on the northeastern side of the fault from Late Ordovician volcanics, sediments and intrusives of the Blayney Volcanics to the west.
3.1.1. Stratigraphy
Bedrock within the area covered by EL 6874 is dominated by Middle and Late Ordovician meta-sediments and the Carboniferous Burraga Granite. Figure 3-1 shows the geology of EL6463 and is based on the geological mapping of the Oberon 1:100,000 geological sheet area by the Australian Geological Survey Organisation and the NSW Geological.

The stratigraphy of EL6463 is poorly understood with different workers providing substantially different interpretations, especially with respect to the relationship of the Burraga sequence to the rest of the stratigraphy. The following descriptions of the rocks with EL6463 is a summary of the ‘consensus’ stratigraphy.
The oldest rocks in the tenement are the middle Ordovician Adaminaby Group which is comprised mainly of variably deformed quartz sandstone and carbonaceous shale. The Adaminaby Group underlies the south eastern parts of the licence area, east of the ‘Lloyds syncline’.
Conformably overlying the Adaminaby Group is the Triangle Formation of the middle Ordovician Kenilworth Group. The Triangle Formation consists of mafic volcaniclastic sandstone, meta-basalt, slate, phyllite, schist, siliceous carbonaceous slate, chert, quartzite and sandstone. The Triangle Group is host to the Lucky Draw and Hackney’s Creek gold deposits in the north eastern part of EL6463.
Geomodelling Limited - PSL NSW Gold Resources 2016 resource report final 20200422.docx
Page 3 of 66
The Triangle Formation rocks are unconformably overlain by the Middle to Late Silurian Campbells Formation of the Mumbil Group. Typically, the formation comprises siltstones overlain by interbedded slate and fine to coarse grained feldspathic meta-sandstone. The Campbells Formation is broadly correlatable with the Anson Formation; host to the McPhillamys Hill gold deposit in the Blayney-Orange district to the northwest.
In faulted contact above the Triangle Formation are sediments of the Early Devonian Crudine Group. The Crudine Group comprises the Dunchurch Formation (feldspathic quartz sandstone with minor slate, ashstone and dacite) and the Buckburraga Slate (laminated silty slate).
Within the ‘Lloyds syncline’ is a sequence of strongly deformed rocks with complex structural and stratigraphic relationships. This sequence comprises a basal slate mapped as the Buckburraga slate overlain by the Excelsior Porphyry. Petrographic analysis of the Excelsior Porphyry shows that is in fact a highly altered volcanic tuff. Above the Excelsior Porphyry is the Hanrahan’s Agglomerate which is actually a polymict breccia of tectonic origin. The Hanrahan’s Agglomerate includes clasts of limestone, amorphous silica and Excelsior Porphyry. Most of the Burraga copper mineralisation occurs in the Hanrahan’s Agglomerate. Fine grained schist, phyllite and minor limestone of the Lovett’s Formation occurs above the Hanrahan’s Agglomerate.
The age and stratigraphic relationship of the ‘Lloyds syncline’ sequence to rocks outside the ‘syncline’ have not been resolved. The sequence is variably interpreted as part of the Late Ordovician Rockley Volcanics or as part of the Silurian Mumbil Group.
In the northeast of EL 6463 is the western margin of the Carboniferous Burraga Granite that has intruded rocks of the Adaminaby Group and Triangle Formation. The Burraga Granite is described as a medium to coarse-grained leucocratic biotite granodiorite that comprises two phases; a massive medium-grained two mica I-type granodiorite and a mediumgrained garnet-muscovite granodiorite that has S-type affinities. The garnet-muscovite phase occurs in the northwest part of the pluton (within EL 6463) adjacent to the Lucky Draw gold deposit. Intruded Ordovician Adaminaby Group sediments have been contact metamorphosed to micaceous quartzite and pelitic quartz-mica schists containing quartz-albite-biotite + cordierite and quartz-biotite-muscovite-albite-andalusite-cordierite assemblages. Intruded Ordovician Triangle Formation sediments have been contact metamorphosed to quartz-feldspar-biotite schist and tremolite-chlorite schist (Rockley Volcanics?). The contact metamorphic aureole associated with the intrusion of the Burraga Granite is reported to be 75100 metres wide.
Minor Quaternary alluvium and gravels are located adjacent to streams in the central part of the tenement where these streams drain part of the Burraga Granite.
3.1.2. Structure
The tenement area has undergone a complex structural and metamorphic history.
Recent re-interpretation of airborne magnetic data suggests that the Godolphin Fault, (a significant control on the 2.3 Moz McPhillamys gold deposit) extends through EL6463 where it juxtaposes Silurian Campbells Formation (to the west) and Ordovician Triangle Formation (to the east; see Figure 3-1 Geological Map of EL6463 and surrounding tenements.).
3.1.3. Gold Mineralisation
The Lucky Draw gold deposit occurs in metasomatised sediments of the Ordovician Triangle Formation immediately below the contact with mafic volcanic rocks inferred to belong to the Rockley Volcanics and very close to the contact with the Carboniferous Burraga Granite. The skarn-like ore displays a gold – bismuth - tellurium association (an “intrusion-related gold” signature) but is generally sulphur-poor with a very low sulphide mineral content. Skarn-like mineral assemblages (including garnet and gedrite), alteration and mineralisation at Lucky Draw including are considered by Sheppard et al . (1995) to be the product of contact metamorphism and hydrothermal activity associated with the intrusion of the Burraga Granite.
3.2. Local Geology
3.2.1. Lucky Draw
The Lucky Draw deposit occurs within Triangle Group sediments, just below the contact with the overlying Rockley Volcanics.
Geomodelling Limited - PSL NSW Gold Resources 2016 resource report final 20200422.docx
Page 4 of 66
The primary control on gold mineralisation is modelled as gently west dipping which is presumably bedding / foliation parallel.
It is not visually clear if there are ore shoots and, if so, what the plunge of such ore shoots is.
The controls on the high grade gold zones at Lucky Draw are also unclear. It may be that the high grade zones are structurally controlled, possibly by east striking, moderately south dipping structures although steep east – west structures and steep north south structures may also be important. Alternatively, structure may be unimportant and high grade zones are following some sort of chemical (carbonate rich zones?) or physical (grain size?) zones within a stratigraphically favourable unit.
The gold mineralisation is intruded by an un-mineralised granitoid stock and associated dykes / sills.
3.2.2. Hackneys Creek
The geology of gold mineralisation at Hackney’s Creek is very similar to that at Lucky Draw. The main difference is that the Hackney’s Creek mineralisation dips more steeply (40° - 70°) to the west.
3.3. Previous Mining and Exploration
Lucky Draw was discovered by Renison Goldfields Consolidated Ltd (RGC) in the mid-1980s and that company mined a total of 1.48 million tonnes grading 3.53 g/t gold between 1988 and 1991. The current resource at Lucky Draw is largely contained in the pod of un-mined mineralisation to the northwest of the pit. This material was not economic in the gold price and cost environment of the early 1990’s. The pit remains open and is reported to be in good condition.
RGC drilled 111 RC holes totalling 3,416.1 metres, 151 DD holes totalling 11,444.3 metres and 7 DD holes with RC precollars for 707.26 m at Lucky Draw.
RGC also drilled a large number of RAB holes and tool hand augur samples for a regional geochemistry survey as well as carrying out ground and aerial magnetic surveys and ground gravity surveys.
Mining grade control was by 1 m deep ditchwitch trenches 5 m apart in oxide material on 2.5 m flitches. Below about 25m below surface grade control was by blasthole sampling initially on a 4 m by 4 m grid and later on a 3 m by 3 m grid.
Similar mineralisation to Lucky Draw was also discovered by RGC in the late 1980’s at the Hackneys Creek prospect, located some 800 metres north of the Lucky Draw deposit. Hackney’s Creek was discovered by drilling a Au-Bi soil geochemistry anomaly. RGC drilled 127 RC totalling 4,101.85 metres, 35 DD holes totalling 5,833.62 metres, 16 DD holes with RC pre-collars for 2242.97m and also dug 59 surface trenches totalling 11,033.7m.
After RGC ceased mining Werrie Gold drilled 9 holes to test for down dip extensions to mineralisation at Hackney’s Creek.

4 Data
4.1. Data Provided
4.1.1. Databases
EYM provided the Lucky Draw and Hackney’s Creek drilling data as a series of excel spreadsheets which had originally been compiled by Brewer Geological Services in 2002 for Marlborough Resources NL from publicly available data held by the NSW Department of Resources and Energy (now Resources and Geoscience NSW; Brewer, 2002). These spreadsheets included collar information (coordinates, total depth, azimuth and hole dip), assays (holeID, from, to, Au and Bi), downhole surveys (holeID, depth, azimuth and dip) and summary geology (HoleID, from, to, lithology). No meta-data such as hole type, hole size, QAQC data, assay method, laboratory, sampling method etc was provided.
GML was able to establish some meta-data from reports and inference of HoleID.
4.1.2. Topography
No topographic data was provided.
The local topography at Lucky Draw and Hackney’s Creek areas is (at least prior to mining) subdued. Therefore, a premining topography surface was created by triangulating hole collar coordinates (excluding holes clearly drilled from within the Lucky Draw pit).
The topographic surfaces are considered acceptable for the resource category reported here (inferred) but would need to be upgraded for higher resource categories.
4.1.3. Lucky Draw Open Pit final survey
EYM provided a text file of points digitised from the pit closure survey plan.
GML triangulated these points to create a final pit surface wireframe used to constrain the Lucky Draw resource.
GML is not aware of any back-fill in the Lucky Draw pit.
4.2. Drilling and Trenching Programmes
4.2.1. RGC
The vast majority of the data used in these resource estimates was completed by RGC.
All downhole surveys were by Eastman single shot.
4.1.2.1 Diamond Drilling
All DD drilling was wireline drilling. All PQ and HQ drilling utilised triple tube core barrels.
The LXD Series holes were NQ DD holes with RC pre-collars. The pre-collars were drilled to the ‘water table’ and then the holes were converted to NQ DD drilling.
The LDD holes were a series vertical PQ/HQ DDs drilled 1987-89, mostly at Lucky Draw but also at Hackney’s Creek. A few LDD holes had short (< 20 m) RC pre-collars. Downhole surveys (unknown method) were taken every 50 m and at the end of hole.
4.1.2.2 Reverse Circulation Drilling
The LRC & LDR series were RC holes.
RC drilling used a 4.5 inch hammer, presumably with a cross-over as face sample hammers had not been invented at this time. There is no other information recorded about the RC drilling methods. Note that RC drilling was a relatively recent development in the late 1980s and many technologies common today were not in use including mast dump, rod carousels, face sample hammers, high capacity compressors, high pressure boosters and dust suppression / sampling.

4.1.2.3 Ditchwitch Trenching
The HAK series are surface ditchwitch trenches at Hackney’s Creek dug to about 1 m depth. The trench locations were surveyed by tape and compass from grid pegs. The trenches were logged and sampled at 2.5 intervals.
HAK041-059 were closely spaced ditchwitch trenches designed to test grade control methods and to inform the short range parts of the variogram.
4.2.2. Werrie Gold
Werrie Gold drilled 6 DD holes (HXD005-HXD010) and 3 RC holes (HRC011-HRC013)

4.3. Drilling Recovery
RC drilling recovery was not recorded.
RC sample moisture content was not recorded.
Diamond drilling recovered was reported to be logged, but no diamond drilling recovery data has been located for Lucky Draw to date. RGC (1988) state that core recovery was poor in the oxide zone within 30m of the surface. RGC (1988) reported 26 intervals of diamond drilling recovery less than 90%.
Four intervals of diamond drilling recovery at Hackney’s Creek of less than 90% was reported by Arundell (1989). It is assumed that all other diamond drilling at Hackney’s Creek was greater than 90%.
4.4. Sub-Sampling Methods
DD core was cut using a diamond core saw and half core sub-sampled. The procedure was to take DD core samples geological contacts to a maximum of 1.0 m.
The RC sub-sampling method was not recorded.
Table 4 shows that within the gold domains the samples are predominantly DD samples.

4.5. Assay Methods
RGC (1988) reported that the assays were all carried out by Australian Assay Laboratories Ltd Orange (AAL, later Analabs, now SGS), however the available data sheets (not laboratory certificates) in various RGC annual EL returns to the NSW mines department show that while the majority of the assays were carried out by Analabs, with some Genalysis assays and a very small number of SGS results (see Table 5).
At Analabs / AAL / SGS the samples were dried on receipt, crushed, if necessary riffle split to – 4kg, hammer milled to 150um, riffle split a 500g sub-sample, milled to -100um. After sample preparation a 50g charge was fire assayed and Au determined by AAS (presumably after aqua regia digest). The lower detection limit for Au was 0.01 ppm.
Geomodelling Limited - PSL NSW Gold Resources 2016 resource report final 20200422.docx
Page 8 of 66
The sample preparation and analytical methods used by Genalysis are not known, but likely very similar to Analabs given that Genalysis were used as an umpire laboratory.
A separate SGS laboratory carried out umpire laboratory check (pulp?) duplicates.

4.6. Surface Survey methods
All RGC drill collars were surveyed to a precision of +/- 0.01 m by Geospectrum (Australia), but the method was not stated. Given the timing it is likely that either a theodolite or a total station instrument was used.
All RCG surveying was to the AGD66 datum.
Collar locations are considered to be accurate to +/- 0.1 m.
4.7. Assay QAQC
No QAQC data have been located for the Lucky Draw or Hackney’s Creek data. Therefore, no conclusions can be made about the quality of data used in these resource estimates.
RGC (1988) report that a standard was submitted every 10 samples. These results have not been located to date.
Arundell, (1989) reports umpire laboratory check samples for 235 pairs of coarse rejects for Hackney’s Creek. The Check laboratory was Analabs (Perth). The original samples (AAL) average 2.17 g/t Au and the check results 2.16 g/t Au. The data reported on by Arundell have not been located to date.
It is known that the Lucky Draw drilling data was used as the input data for the reserve estimate used to design the RGC open pit mined 1988-93 and that this reserve model reconciled adequately to grade control data. This shows that the drilling assays are not significantly biased and were of adequate precision for mine planning.
The resource categorisation reflects the lack of QAQC data.

4.8. Data Validation and Import into Minesight
Prior to use in Minesight software, all the data was compiled from the provided spreadsheets into collar, downhole survey, assay and logging spreadsheets. Checks were performed for minimum values, maximum values, out of range values (e.g. azimuth > 360°) and overlaps. Any such flagged data were checked against the original data (log sheets, downhole surveys, assay certificates) and fixed as appropriate.
Any values provided as -9999 or -99 (missing data) were converted to -1 (null) on import into the Minesight. Below detection limit data were imported as half the detection limit.
Minesight performs additional checks for out of range data, overlapping and missing intervals on import.

5 Domaining
5.1. Lucky Draw Gold Grade Domain
The geological controls on gold mineralisation at the Lucky Draw not well understood. It is known that gold mineralisation is restricted to quartz absent Mg-Fe-Al rich schists and is associated with a chlorite-geedrite-garnet-biotitie-staurolitehercynite assemblage. The controls on the orientation and intensity gold mineralisation are poorly understood.
In view of this very limited understanding of the controls on gold mineralisation it was decided to interpret gold grade domains from gold grade data only. The lack of geological understanding of the gold mineralisation increases the risk that the gold grade domains are poorly / incorrectly interpreted. This risk is reflected in the resource classification (see section 8).
The Luck Draw gold grade domain was modelled at a nominal 0.2 g/t to a minimum width of 2 m and a maximum internal dilution of 2 m. 0.2 g/t was selected as the nominal interpretation grade purely on economic grounds because visual inspection of the drilling data and cumulative probability plots show no natural lower cutoff to gold mineralisation. 0.2 g/t is approximately 50% of a likely open mining cut off grade (~0.5 g/t Au) and so the domain interpretation should be robust at such a mining cutoff grade.
There is only one Au grade domain. Higher grade mineralisation (above 0.5 g/t to 2.0 g/t) is continuous and could be interpreted as a high grade domain. There is no statistical evidence of mixed populations. With additional data and / or improved geological understanding it may be that more than one gold grade domain may be interpreted.
The gold grade domain was not interpreted in the granitoid stock.
The gold grade domain was interpreted as polygon strings on drill sections. The strings were snapped to assay intervals so that later coding of the assay data would honour the interpreted domain boundary.
The strings were later linked to form the domain wireframe. Not all strings were linked as an assessment in 3D showed that the continuity observed in section did not extend between sections.
5.2. Hackney’s Creek Gold Grade Domain
The Hackney’s Creek gold domain interpolation largely followed the methods used for Lucky Draw.
The Hackney’s Creek gold mineralisation is generally lower grade than at Lucky Draw.
The primary control on gold mineralisation is modelled as moderately (~50°) west dipping which is presumably bedding / foliation parallel. Secondary control is a series of inferred north striking, steeply east dipping faults with normal movement offsetting stratigraphy and mineralisation and also commonly bounding mineralisation.
5.3. Oxidation Domains
No oxidation domains were interpreted at Lucky Draw or Hackney’s Creek because no weathering or oxidation logging was available.
5.4. Assay coding
The raw assays were coded for DOM (gold grade domain) from the domain wireframes,
The coding of the assays was validated using the filtering function in the Minesight drillview to show all samples meeting the domain criteria (i.e. > 0.20 g/t Au) and not coded as in the gold grade domain wireframe. The visible samples were investigated to ensure that they had been deliberately excluded from the wireframe (usually because they did not show sufficient geological continuity for inclusion in a resource). Similarly, all samples not meeting the domain criteria and coded as inside the domain wireframe were viewed and checked.

6.1.3. Extreme Values
Cumulative probability plots of the composite data within the Lucky Draw gold domain show a slope change above about 25 g/t Au, suggestive of a separate high grade population (see Figure 6-2).

A histogram of the gold composites within the Lucky Draw gold domain is continuous to about 21 g/t Au.
Visual examination of the gold grades showed that the very high (> 25 g/t Au) zones do not form continuous zones and so may not be estimated separately.

6.1.4. Variography
All the experimental variograms were correlograms of the composited data with no top cut. The lag tolerance was always set to half the lag.
Initially a downhole variogram was generated using 2.5 m lags and used to determine the nugget from a single sill spherical model largely honouring the first two lags.
Geomodelling Limited - PSL NSW Gold Resources 2016 resource report final 20200422.docx
Page 13 of 66
Next a fan of experimental variograms at 10° increments was created in the plane of the mineralised vein. The variogram with the maximum continuity in this plane was designated the major axis. A second fan of experimental variograms was then created in the plane normal to the major axis and the minor axis designated as the direction of least continuity with the semi-major axis being the direction normal to both the major and minor axes.
The lag distance and angular tolerance (maximum 22.5°) were then varied for each axis in order to get the best structured experimental variogram for each axis.
MSDA was then used to simultaneously view the experimental variograms in the major, semi-major and minor axes. The nugget as determined from the downhole variogram was fixed and spherical variogram models manually fitted. It was found that only a single sill was necessary to model the experimental variograms.
The experimental variograms (Figure 6-4 to Figure 6-7 ) show shoots plunging gently towards the southwest (240°), but fairly isotropic within the plane of mineralisation (240/20W).

A composite length of 2.5 m was selected as this requires the splitting of few raw samples (6 or 0.7% of the 894 raw samples; see Figure 6-8).

6.1.3. Extreme Values
Cumulative probability plots of the composite data within the Hackney’s Creek gold domain show a straight line indicative of a single log normally distributed population with no extreme values (see Figure 6-2).
Similarly, the histogram of the gold composites within the Hackney’s Creek gold domain is continuous to about 10 g/t Au.
In view of these observations no topcut was applied to the gold composites prior to geostatistical analysis or grade interpolation.

6.1.4. Variography
All the experimental variograms were correlograms of the composited data with no top cut. The lag tolerance was always set to half the lag.
Initially a downhole variogram was generated using 2.5 m lags and used to determine the nugget from a single sill spherical model largely honouring the first two lags.
Next a fan of experimental variograms at 10° increments was created in the plane of the mineralised vein. The variogram with the maximum continuity in this plane was designated the major axis. A second fan of experimental variograms was then created in the plane normal to the major axis and the minor axis designated as the direction of least continuity with the semi-major axis being the direction normal to both the major and minor axes.
The lag distance and angular tolerance (maximum 22.5°) were then varied for each axis in order to get the best structured experimental variogram for each axis.
Geomodelling Limited - PSL NSW Gold Resources 2016 resource report final 20200422.docx
Page 18 of 66
MSDA was then used to simultaneously view the experimental variograms in the major, semi-major and minor axes. The nugget as determined from the downhole variogram was fixed and spherical variogram models manually fitted. It was found that only a single sill was necessary to model the experimental variograms.
The experimental variograms (Figure 6-4 to Figure 6-7 ) show that most of the variance occurs within the first 10 m.
The minor axis variogram was very poorly structures, so the downhole variogram model was used as a proxy for the minor axis.

No density data was available for Lucky Draw.
At Hackney’s Creek density data of 260 samples from 24 Diamond holes have been reported in aggregate by Arundell (1989; see Table 11). The density values were determined by core immersion, but the exact equipment used, the laboratory used and whether the core was wax coated were not recorded.

In both the Lucky Draw and Hackney’s Creek models a density of 2.6 t/m[3] has been assumed, based on a typical mineralisation lithology (quartz and schist) and the vague memories of Russell Hooper, the processing manager for RGC.
It is likely that the bulk density varies significantly with weathering and also to a lesser degree varies with lithology and depth.

8 Resource Classification
8.1. Method
Both the Lucky Draw and Hackney’s Creek gold resource estimates are classified as inferred in accordance with the JORC 2012 code.
While the (drilling) data density would commonly allow higher resource categories at Lucky Draw, the lack of geological understanding, QAQC data to demonstrate the sampling and assay quality and density data preclude the possibility of higher confidence resource categories.
8.2. Economic Justification
Open pit mining is assumed based on the width and near surface location of the mineralisation. Current gold prices would likely result in a significantly deeper optimal pit than the pit design mined by RGC during the early 1990’s.
High metallurgical recovery (>90%) is assumed at Lucky Draw based on the successful operation of the Lucky Draw gold processing plant (conventional crushing and milling followed by CIP leach and electrowinning).
Preliminary metallurgical test work was carried out on 3 samples of ore from the Hackney’s Creek Deposit by RGC NSW Ltd, showing a work index ranging from 7.4-8.0 kWh/t and a potential gold extraction of 89-95% in a 24 hour cyanide leach. These results compared favourably to the Lucky Draw ore, with slightly higher recoveries potentially indicated.

10 Validation
10.1. Comparison to Historical Production records
The Lucky Draw model was compared to historical production from the open pit reported by RGC (RGC, 1992). and the RGC pre-mining reserve estimate (Arundell, 1989). RGC did not report the cutoff grade used for mining and so a cutoff grade of 0.5 g/t Au has been assumed). The resource estimate was reported from between a pre-mining topographic surface and the final pit survey surface. The pre-mining topographic surface was created by triangulating the collars of drillholes drilled prior to mining.
The current resource estimate compares favourably to the RGC grade control
