MINERAL RESOURCE AND ORE RESERVE STATEMENT AS AT 31 MARCH 2016
HIGHLIGHTS
- Group Ore Reserves increased by 6% from 2.01 million ounces to 2.13 million ounces after accounting for mining depletion of 330,000 ounces.
- Group Mineral Resources increased by 5% from 7.63 million ounces to 8.01 million ounces after accounting for mining depletion of 330,000 ounces.
- Group JORC compliant Ore Reserves estimate updated to 60.8 million tonnes at 1.09 g/t gold for 2.13 million ounces compared with the estimate of 59.1 million tonnes at 1.06g/t gold for 2.01 million ounces as at 31 March 2015. This is a 119,000 ounce (6%) increase on the 2015 Reserve and a 445,000 ounce (22%) increase on the 2015 Reserve depleted for 2016 mining.
- Group JORC compliant Mineral Resources estimate updated to 261.7 million tonnes at 0.95g/t gold for 8.01 million ounces compared to 249.1 million tonnes at 0.95g/t gold for 7.63 million ounces as at 31 March 2015. This is a 380,000 ounce (5%) increase on the 2015 Resource and a 710,000 ounce (10%) increase on the 2015 Resource depleted for 2016 mining.
- The Ore Reserves support robust mining schedules and a long mine life at Duketon (Garden Well 7+ years, Rosemont 5+ years, Moolart Well 4+ years). Regis is confident that with the current Ore Reserves and other highly prospective target areas within trucking distance of existing operations, the 10 million tonne per annum processing capacity at Duketon will be fully utilised for many years to come.
- The major contributors to the increase in Ore Reserves net of depletion of 445,000 ounces were:
- o Maiden Ore Reserves of 226,00 ounces at Gloster and 136,000 ounces at Baneygo;
- o Addition of 81,000 ounces at Rosemont through extensional drilling and improved optimisations; and
- o Addition of 27,000 ounces at Moolart Well through infill drilling.
- The Moolart Well mine life has been extended by the nearby Gloster deposit which is currently being developed with a maiden Ore Reserve of 7.0MT at 1.00g/t for 226,000 ounces.
- An aggressive exploration programme at the Duketon project continues to be focussed on high potential areas for Mineral Resource expansions with a view to delivering further extensions to the mine life of the current operations. Current targets yielding highly encouraging results include the Tooheys Well deposit south of Garden Well (refer separate ASX announcement (14th June 2016), and extensions to Baneygo (Idaho) and Dogbolter (Coopers).

RESOURCE AND RESERVE UPDATE SUMMARY
Group Mineral Resources
The JORC compliant Group Mineral Resources as at 31 March 2016 are estimated to be 261.7 million tonnes at 0.95g/t Au for 8.01 million ounces of gold, compared with the estimate at 31 March 2015 of 249.1 million tonnes at 0.95g/t Au for 7.63 million ounces of gold. The change in the Group Mineral Resources is primarily the result of addition of new deposits.

Mineral Resources are reported inclusive of Ore Reserves and include all exploration and resource definition drilling information, where practicable, up to 31 March 2016 and have been depleted for mining to 31 March 2016.
Mineral Resources are constrained by optimised open pit shells developed with operating costs and a long term gold price assumption of A$2,000 per ounce for the purpose of satisfying "reasonable prospects for eventual extraction" (JORC 2012).

Group Ore Reserves
The JORC compliant Group Ore Reserves as at 31 March 2016 are estimated at 60.8 million tonnes at 1.09g/t Au for 2.13 million ounces of gold, compared with the estimate at 31 March 2015 of 59.1 million tonnes at 1.06g/t Au for 2.01 million ounces of gold.
The change in the Group Ore Reserve from March 2015 to March 2016 is as follows:
| Total Ore Reserve | |||
|---|---|---|---|
| Tonnes(Mt) | Gold Grade(g/t) | Gold Metal(koz) | |
| 31 March 2015 | 59.1 | 1.06 | 2,006 |
| Depleted by Mining to 31/3/16 | -10.6 | 0.96 | -326 |
| 31 March 2015 Net of Depletion | 48.5 | 1.08 | 1,680 |
| 31 March 2016 | 60.8 | 1.09 | 2,125 |
| % Variation net of Depletion | 21% | 22% |
The re-estimation of Group Ore Reserves resulted in a 21% increase in tonnes and 22% increase in ounces after allowing for depletion by mining. This was primarily the result of:
- The inclusion of maiden Ore Reserves from Gloster and Baneygo deposits;
- a review of current pit design parameters including costs, metallurgical and geotechnical performance of mining projects to date; and

• the inclusion of further drilling results.
A long term gold price of A$1,400 per ounce was used in Ore Reserve pit optimisations. Ore Reserves have been depleted for mining to 31 March 2016.

COMMENTARY ON CHANGES BY PROJECT
Garden Well
The Garden Well JORC compliant Mineral Resource as at 31 March 2016 is 75.8 million tonnes at 0.88g/t Au for 2.14 million ounces, compared to 86.7 million tonnes at 0.89g/t Au for 2.47 million ounces at 31 March 2015.
The Garden Well JORC compliant Ore Reserve as at 31 March 2016 is 28.8 million tonnes at 0.89g/t Au for 0.83 million ounces, compared to 34.5 million tonnes at 0.91g/t Au for 1.01 million ounces at 31 March 2015.
The change in the Garden Well Ore Reserve from March 2015 to March 2016 is as follows:
| Total Ore Reserve - Garden Well | |||
|---|---|---|---|
| Tonnes(Mt) | Gold Grade(g/t) | Gold Metal(koz) | |
| 31 March 2015 | 34.5 | 0.91 | 1,009 |
| Depleted by Mining to 31/3/16 | -5.6 | 0.87 | -158 |
| 31 March 2015 Net of Depletion | 28.9 | 0.92 | 851 |
| 31 March 2016 | 28.8 | 0.89 | 827 |
| % Variation Net of Depletion | 0% | -2% |
The reoptimisation and subsequent pit redesign at Garden Well resulted in a minor decrease in tonnes and 2% decrease in ounces after allowing for depletion by mining. This was primarily the result of review of 2016 reconciliation data against the March 2015 Ore Reserve and update of current pit design parameters including costs, metallurgical performance and infill drilling.
Rosemont
The Rosemont JORC compliant Mineral Resource as at 31 March 2016 is 28.0 million tonnes at 1.48g/t Au for 1.33 million ounces, compared to 28.3 million tonnes at 1.33g/t Au for 1.21 million ounces at 31 March 2015.
The Rosemont JORC compliant Ore Reserve as at 31 March 2016 is 11.6 million tonnes at 1.51g/t Au for 0.56 million ounces, compared to 13.2 million tonnes at 1.35g/t Au for 0.57 million ounces at 31 March 2015. The change in the Rosemont Ore Reserve from March 2015 to March 2016 is as follows:
| Total Ore Reserve - Rosemont | |||
|---|---|---|---|
| Tonnes(Mt) | Gold Grade(g/t) | Gold Metal(koz) | |
| 31 March 2015 | 13.2 | 1.35 | 574 |
| Depleted by Mining to 31/3/16 | -2.3 | 1.24 | -91 |
| 31 March 2015 Net of Depletion | 10.9 | 1.38 | 484 |
| 31 March 2016 | 11.6 | 1.51 | 564 |
| % Variation Net of Depletion | 5% | 14% |
The reoptimisation and subsequent pit redesign at Rosemont resulted in a 5% increase in tonnes and 14% increase in ounces after allowing for depletion by mining, primarily due to:
- a review of current pit design parameters including costs, metallurgical and geotechnical performance plus an updated Mineral Resource estimate guided by reconciliation data that better reflects high-grade mineralisation ; and
- the inclusion of further drilling results.

Moolart Well
The Moolart Well JORC compliant Mineral Resource as at 31 March 2016 is 36.1 million tonnes at 0.71g/t Au for 0.82 million ounces, compared to 47.3 million tonnes at 0.72g/t Au for 1.09 million ounces at 31 March 2015.
The Moolart Well JORC compliant Ore Reserve as at 31 March 2016 is 4.8 million tonnes at 0.93g/t Au for 0.14 million ounces, compared to 6.5 million tonnes at 0.92g/t Au for 0.20 million ounces at 31 March 2015. The change in the Moolart Well Ore Reserve from March 2015 to March 2016 is as follows:
| Total Ore Reserve - Moolart Well | |||
|---|---|---|---|
| Tonnes(Mt) | Gold Grade(g/t) | Gold Metal(koz) | |
| 31 March 2015 | 6.5 | 0.92 | 194 |
| Depleted by Mining to 31/3/16 | -2.7 | 0.89 | -77 |
| 31 March 2015 Net of Depletion | 3.8 | 0.95 | 117 |
| 31 March 2016 | 4.8 | 0.93 | 144 |
| % Variation Net of Depletion | 15% | 14% |
The reoptimisation and subsequent pit redesign at Moolart resulted in a 15% increase in tonnes and 14% increase in ounces after allowing for depletion by mining. This was primarily the result of additional drilling in and around known Mineral Resources to expand and improve confidence.
Duketon Satellite Deposits
The combined JORC compliant Mineral Resource for Duketon satellite deposits as at 31 March 2016 is 48.7 million tonnes at 0.96g/t Au for 1.50 million ounces, compared to 13.6 million tonnes at 1.46g/t Au for 0.64 million ounces at 31 March 2015.
The material change in total Mineral Resource ounces for the combined Duketon satellite deposits are as follows:
Gloster:
• Mineral Resource purchased during the year and therefore not previously quoted by Regis. Updated to JORC 2012 utilising drilling completed by Regis in the past year.
Baneygo:
• Mineral Resource has been updated from JORC 2004 to JORC 2012 utilising new drilling completed by Regis Resources in the past year.
The combined JORC compliant Ore Reserve for Duketon satellite deposits as at 31 March 2016 is 15.5 million tonnes at 1.18g/t Au for 0.59 million ounces, compared to 4.8 million tonnes at 1.47g/t Au for 0.23 million ounces at 31 March 2015.
The change in the combined satellite deposits Ore Reserve from March 2015 to March 2016 is as follows:
| Total Ore Reserve - Satellite Deposits | |||
|---|---|---|---|
| Tonnes(Mt) | Gold Grade(g/t) | Gold Metal(koz) | |
| 31 March 2015 | 4.8 | 1.47 | 229 |
| Depleted by Mining to 31/3/16 | 0.0 | - | 0 |
| 31 March 2015 Net of Depletion | 4.8 | 1.47 | 229 |
| 31 March 2016 | 15.5 | 1.18 | 590 |
| % Variation net of Depletion | 221% | 158% |

There has been a 221% increase in tonnes and 158% increase in ounces at the Duketon satellite deposits. This was primarily the result of the inclusion of maiden Ore Reserve estimates based on the revised Mineral Resource estimates for Gloster and Baneygo utilising pit optimisation parameters based on nearby operating Duketon Projects. Refer to separate ASX announcement on 1st January 2016 (Baneygo Mineral Resource estimate) and 14th March 2016 (Gloster maiden Mineral Resource estimate and Ore Reserve and maiden Baneygo Ore Reserve).

Garden Well
Mineral Resource
Geology and Geological Interpretation
Garden Well is located on the eastern limb of the Erlistoun syncline of the Duketon Greenstone Belt. The gold of the Garden Well Deposit occurs as supergene mineralisation within upper Archaean regolith and as hypogene mineralisation in fresh rock. No significant amounts of gold occur in the transported quaternary clay sequence.
The gold is associated with intensely sheared and folded ultramafic and shale units that have been hydrothermally altered to a silica-carbonate-fuchsite-chlorite-pyrite-arsenopyrite assemblage, and underlying chert units.
The gold mineralisation trends roughly north-south over a distance of 2,100m and dips 50º to 60º east which is sub-parallel to the ultramafic-sediment contact.
Sampling and Sub-sampling
The Garden Well deposit was sampled using reverse circulation (RC), aircore (AC) and diamond drill holes (DD) on a nominal 40m by 40m grid spacing.
Beneath the transported horizon (waste overburden, considered devoid of gold mineralisation and regularly not sampled) 1m AC samples were obtained by riffle splitter and 1m RC samples were obtained by cone splitter, with both being utilised for lithology logging and assaying.
Diamond core was used for geotechnical and density measurements as well as lithology logging and assaying. HQ diameter diamond coring has been used through chert and has been whole core sampled, NQ2 diameter coring has been used through ultramafic and shale and half core sampled with half of the core being kept in storage. The core has predominantly been sampled at 1m intervals, with some sampling on geological intervals.
All samples were dried, crushed and pulverised to achieve 85% passing 75µm.
Sample Analysis Method
All gold assaying was completed by commercial laboratories utilising a 30g, 40g, or 50g charge for fire assay analysis with AAS finish.
Drilling Techniques
In the resource area AC drilling with an 89mm diameter AC blade accounts for 13% of the drilling metres with an average hole depth of 91m. RC drilling with a 139mm diameter face sampling hammer accounts for 56% of the drilling meters in the resource area with an average hole depth of 151m.
Diamond drilling comprising HQ triple tube and NQ2 sized core accounts for 27% of the drilling meters in the resource area with an average hole depth of 376.2m. RC Pre-collar drill holes

with NQ2 diamond tails account for 4% of the drilling meters in the resource area with an average hole depth of 371.6m. Core orientations were completed using orientation tools.
Estimation Methodology
The estimation methodology used was Multiple Indicator Kriging (MIK) with block support adjustment to estimate gold resources into blocks with dimensions of 20m (east) by 40m (north) by 5m (elevation). MIK of gold grades used indicator variography based on the two metre resource composite sample grades.
Gold grade continuity was characterised by indicator variograms at 14 indicator thresholds spanning the global range of grades. A block support adjustment was used to estimate the recoverable gold resources at Garden Well. The shape of the local block gold grade distribution has been assumed lognormal and an additional adjustment for the "Information Effect" has been applied to arrive at the final resource estimates.
Exploratory data analysis, variogram calculation and modelling, and resource estimation have been performed using software designed specifically for estimation of recoverable resources.
The sample data set containing all available assaying were composited to two metre intervals each located by their mid-point co-ordinates and assigned a length weighted average gold grade. A combination of outlier high grade composites being ignored for each sub-domain for the generation of the indicator statistics, and selection of the median instead of mean for the highest indicator threshold were used to guard against a few higher grades within the population from having a disproportional influence on the gold estimation.
Resource Classification
The resource model uses a classification scheme producing a resource code based on the number and location of gold composites used to estimate proportions and gold grade of each block. This is based on the principle that larger numbers of composites, which are more evenly distributed within the search neighborhood, will provide a more reliable estimate.
The strategy adopted in the current study uses Category 1 and 2 from the 3 pass octant search strategy as Indicated resource and Category 3 as Inferred resource. This results in a geologically sensible classification whereby Category 1 and 2 are surrounded by data in close proximity. Category 3 blocks occur on the peripheries of drilling but are still related to drilling data within reasonable distances. No Measured resource has been applied in the classification method apart from stockpiled ore.
Cut-off Grade
The cut-off grade of 0.4g/t for the stated Mineral Resource estimate is determined from economic parameters and reflects the current and anticipated mining practices. The model is considered valid for reporting and open pit mine planning at a range of lower cut-off grades up to a lower cut-off grade of 1.0g/t Au.
Mining and Metallurgical Methods and Parameters and other modifying factors considered to date
The Mineral Resources utilise standardised operating parameters and a gold price of $2,000 per ounce to optimise an open pit shell. It assumes open cut mining practices with a moderate level of mining selectivity achieved during mining. It is also assumed that high quality grade control will be applied to ore/waste delineation processes. This is consistent with current mining practices at Garden Well.
A gold recovery of 93% was used to determine Mineral Resources which has been based on potential recoveries indicated by metallurgical testwork in the Duketon area by Regis, production data and ongoing testwork to determine cyanidable gold recoveries.
Where metallurgical testwork and actual recovery data exists it will be applied in the relevant Ore Reserve but is not back applied to the Mineral Resource estimate.

Ore Reserve
Material Assumptions for Ore Reserve
The following material assumptions apply to the Ore Reserve:
- Gold price of $1,400 per ounce;
- Current operational capital and operating cost structure;
- Current operational mining and metallurgical performance; and
- Current operational geotechnical and hydrogeological performance.
Ore Reserve Classification
The classification of the Garden Well Ore Reserve has been carried out in accordance with the recommendations of the JORC code 2012. It is based on the density of the drilling, estimation methodology, the orebody experience and the mining method employed.
All Probable Ore Reserves have been derived from Indicated Mineral Resources. No Measured Mineral Resources were contained within the block model and no Proved Ore Reserves have been established apart from stockpiled ore.
Mining Method
The mining method assumed in the Ore Reserve study is the same as that currently employed at the Garden Well Gold Mine, which utilises drill and blast, excavator and truck open pit mining. The existing pit has been designed to be developed in a series of progressive cutbacks.
Geotechnical and hydrogeological recommendations have been applied during pit optimisation and incorporated in design with ongoing reviews. A 5% grade dilution factor has been used on the Resource model. A mining recovery factor of 60% has been applied to the lower confidence estimation pass 2 blocks.
Processing Method
The existing Garden Well crushing, grinding and CIL Processing facility will be utilised to treat the Ore Reserve. Based on feasibility testwork, actual data and testwork since the commencement of production broad recovery variations have been reflected in domains applied to the Resource model for use in the Ore Reserve estimation. Each domain applies a fixed tail gold grade during the Ore Reserve estimation process. The resultant average recovery factor of the Ore Reserve is approximately 87% based on final tonnages and grades of ore types.
Cut-off Grade
Variable lower MIK block cut-off grades have been applied to the resource block model in estimating the Ore Reserve. The lower cuts have been selected with consideration to mineability and cash operating margins. No upper cut has been applied to the Ore Reserve as this has been adequately dealt with in the Mineral Resource estimation stage.
Estimation Methodology
Refer to Mineral Resource section.
Material Modifying Factors
There are no material modifying factors that need to be highlighted with the Ore Reserve. Garden Well is an operating mine. All regulatory leasing, approvals, licensing, agreements and current infrastructure are in place, which considers this estimation higher than that of a feasibility study.

Rosemont
Mineral Resources
Geology and Geological Interpretation
Rosemont gold deposit is hosted in a quartz dolerite zone of a dolerite sill intruding ultramafic and argillaceous sedimentary units of the western limb of the Erlistoun Syncline in the Duketon Greenstone Belt.
Gold mineralisation is associated with moderately sheared quartz dolerite with carbonatepyrite-chlorite alteration. Most gold occurs below the weathered profile in saprock and fresh rock with the upper saprolite being leached of gold.
The mineralisation trends NNW over a strike length of 4.9km and dips steeply at 85º west.
Sampling and Sub-sampling
The Rosemont deposit was sampled using reverse circulation (RC), aircore (AC) and diamond drill holes (DD) on a nominal 40m by 40m initial grid spacing. Infill drilling in the main zone has reduced the effective spacing between holes to 10m to 20m (east) by 20m (north) to a depth of 100m from surface. Infill drilling in the north zone has reduced the effective spacing between holes to 20m (east) by 20m (north) to a depth of 200m from surface.
For the Regis managed drilling 1m RC samples were obtained by cone splitter and were utilised for lithology logging and assaying. Diamond core was used for geotechnical and density measurements as well as lithology logging and assaying. HQ diameter triple tube diamond core was used for bulk density and geotechnical measurements as well as assaying. Half of the core was sampled with half of the core being kept in storage. The core has predominantly been sampled at 1m intervals, with some sampling on geological intervals.
The Regis managed drilling samples were dried, crushed and pulverised to achieve 85% passing 75µm.
Sample Analysis Method
The Regis managed drilling samples were predominantly fire assayed using a 50g charge with some fire assay using a 40g charge at commercial laboratories. For historical drilling the samples were dried, crushed and pulverised to achieve 80% passing 75µm and were predominantly fire assayed using a 50g charge, with the 4m field composites assayed via aqua regia on 50g pulps using an AAS finish.
Drilling Techniques
In the resource area AC drilling with an 89mm diameter AC blade accounts for <1% of the drilling metres with an average hole depth of 31.6m, RC drilling completed with a 139mm diameter face sampling hammer accounts for 78% of the drilling meters in the resource area (inclusive of RC pre-collars) with an average hole depth of 120.2m.
Diamond drilling (comprising HQ triple tube for the Regis managed drilling and unknown for the historical drilling) accounts for 21% of the drilling meters in the resource area with an average hole depth of 291.8m. Core orientations were completed using orientation tools at the end of each run for Regis managed drilling, and unknown for the historical drilling.
Estimation Methodology
The estimation methodology used was Multiple Indicator Kriging (MIK) with block support adjustment to estimate gold resources into blocks with dimensions of 15m (east) by 20m (north) by 5m (elevation). MIK of gold grades used indicator variography based on the two metre resource composite sample grades.
Gold grade continuity was characterised by indicator variograms at 14 indicator thresholds spanning the global range of grades. A block support adjustment was used to estimate the recoverable gold resources at Rosemont. The shape of the local block gold grade distribution has been assumed lognormal and an additional adjustment for the "Information Effect" has been applied to arrive at the final resource estimates.

Exploratory data analysis, variogram calculation and modeling, and resource estimation have been performed using software designed specifically for estimation of recoverable resources using MIK.
The sample data set containing all available assaying were composited to two metre intervals each located by their mid-point co-ordinates and assigned a length weighted average gold grade. The selection of the median instead of mean for the highest indicator threshold were used to guard against a few higher grades within the population from having a disproportional influence on the gold estimation. Reconciliation studies have shown that the truncation of outlier high grade composites for the generation of indicator statistics in the previous estimate is not required.
Resource Classification
The resource model uses a classification scheme producing a resource code based on the number and location of gold composites used to estimate proportions and gold grade of each block. This is based on the principle that larger numbers of composites, which are more evenly distributed within the search neighborhood, will provide a more reliable estimate.
The strategy adopted in the current study uses Category 1 from the 3 pass octant search strategy as Measured resource, Category 2 as Indicated resource and category 3 as Inferred resource. This results in a geologically sensible classification whereby Category 1 and 2 are surrounded by data in close proximity. Category 3 blocks may occur on the peripheries of drilling but are still related to drilling data within reasonable distances.
Cut-off Grade
The cut-off grade of 0.4g/t for the stated Mineral Resource estimate is determined from economic parameters and reflects the current and anticipated mining practices. The model is considered valid for reporting and open pit mine planning at a range of lower cut-off grades up to a lower cut-off grade of 1.0g/t Au.
Mining and Metallurgical Methods and Parameters and other modifying factors considered to date
The Mineral Resources utilise standardised operating parameters and a gold price of $2,000 per ounce to optimise an open pit shell. It assumes open cut mining practices with a moderate level of mining selectivity achieved during mining. It is also assumed that high quality grade control will be applied to ore/waste delineation processes. This is consistent with current mining practices at Rosemont.

Where metallurgical testwork and actual recovery data exists it will be applied in the relevant Ore Reserve but is not back applied to the Mineral Resource estimate.
Ore Reserve
Material Assumptions for Ore Reserve
The following material assumptions apply to the Ore Reserve:
- Gold price of $1,400 per ounce;
- Current operational capital and operating cost structure;
- Current operational mining and metallurgical performance; and
- Current operational geotechnical and hydrogeological performance.
Ore Reserve Classification
The classification of the Rosemont Ore Reserve has been carried out in accordance with the recommendations of the JORC code 2012. It is based on the density of the drilling, estimation methodology, the orebody experience and the mining method employed.

All Proved and Probable Ore Reserves have been derived from Measured and Indicated resources respectively.
Mining Method
The mining method assumed in the Ore Reserve study is the same as that currently employed at the Rosemont Gold Mine, which utilises drill and blast, excavator and truck open pit mining. The existing pit has been designed to be developed in a series of progressive cutbacks. The Ore Reserve pit is designed as a further series of extensional cutbacks to the existing pit.
Geotechnical and hydrogeological recommendations have been applied during pit optimisation and incorporated in design with ongoing reviews. Mining dilution and ore loss factors have been dealt with in the estimation of the MIK Mineral Resource.
Processing Method
The existing Rosemont crushing and grinding Plant and the Garden Well CIL Processing facility will be utilised to treat the Ore Reserve and a recovery factor of 93% has been assumed in the estimation of the Ore Reserve.
Full feasibility level metallurgical testwork was completed on the original Rosemont resource prior to the construction and commissioning of the Rosemont Crushing and Grinding Plant and the expansion of the Garden Well CIL Processing Plant. The metallurgical results from the full scale Rosemont crushing and grinding facility and the Garden Well CIL Processing Plant have been incorporated into the Ore Reserve estimation.
Cut-off Grade
A lower MIK block cut-off grade of 0.4g/t has been applied to the resource block model in estimating the Ore Reserve. The lower cut has been selected with consideration to mineability and cash operating margins. No upper cut has been applied to the Ore Reserve as this has been adequately dealt with in the Mineral Resource estimation stage.
Estimation Methodology
Refer to Mineral Resource section.
Material Modifying Factors
There are no material modifying factors that need to be highlighted with the Ore Reserve. Rosemont is an operating mine. All regulatory leasing, approvals, licensing, agreements and current infrastructure are in place, which considers this estimation higher than that of a feasibility study.

Moolart Well
Mineral Resource
Geology and Geological Interpretation
Moolart Well is a blind gold deposit with several styles of gold occurring within the regolith profile. In transported regolith extending to 20m depth, a laterite zone is defined by a coherent sub-horizontal gold blanket consisting of colluvial ironstone and pisolites in a clayey iron rich matrix. The laterite zone has an average thickness of 4m, extends over 5km N-S and 1km E-W and in some areas extends within 2m of the surface.
Below the laterite zone in the residual regolith is the oxide zone extending from 20m to 70m vertical depth with a similar lateral extent to the laterite zone.
Oxide mineralisation consists of numerous primary moderate to steep 60° east dipping gold bearing structures preserved in the clay rich residual profile and sub-horizontal supergene gold developed in the lower part of the profile. Host rocks for the oxide zone are a sequence of moderate to steep east dipping archaean mafic rocks, including basalt and dolerite sills, and ultramafic flow sequence, intruded by late stage high level diorite and quartz-diorite sills and dykes.
Sampling and Sub-sampling
The Moolart Well deposit was sampled using reverse circulation (RC), aircore (AC) and diamond drill holes (DD) on a nominal 50m by 50m initial grid spacing. Infill drilling in the highest potential oxide/fresh areas has reduced the effective spacing to 25m by 25m. Shallow AC grade control drilling has been included for the laterite estimation and is spaced at 12.5m by 12.5m.
One metre AC samples were obtained by riffle splitter and half metre samples via cone splitter for the laterite AC grade control and 1m RC samples were obtained by cone splitter, with all being utilised for lithology logging and assaying.
Diamond core was used for geotechnical and density measurements as well as lithology logging and assaying. The core has predominantly been sampled at 1m intervals, with some sampling on geological intervals. RC sampling prior to 2005 involved taking a speared 4m field composite, with the 1m cone split sample only assayed for the 4m field composites returning a gold value above 0.1g/t.
AC sampling prior to 2005 involved taking a speared 4m field composite, with any 4m field composites returning a gold value above 0.1g/t being re-sampled via spearing the 1m samples. All samples were dried, crushed and pulverised to at least 85% passing 75µm.
Sample Analysis Method
All gold assaying was completed by commercial laboratories. The laterite grade control samples were assayed via a 40g charge aqua regia digest with AAS finish, with the remainder of the assaying using either a 40g or 50g charge for fire assay analysis with AAS finish.
Drilling Techniques
In the resource area AC drilling was completed with an 89mm diameter AC blade, RC drilling was completed with a 139mm diameter face sampling hammer and DD was completed at PQ sized core. Core orientations were completed using chalk and spear.
Estimation Methodology
The estimation methodology used for both the laterite and oxide/fresh estimates was ordinary kriging (OK) with no change of support. Block model dimensions used in the laterite estimate are 6.25m (east) by 6.25m (north) by 1m (elevation) with no sub-blocking. Block model dimensions used in the oxide/fresh estimate are 5m (east) by 10m (north) by 2.5m (elevation), with no sub-blocking.
The laterite OK estimation was constrained within 0.4g/t Au mineralisation zone interpretation (top and bottom of ore) accurately defined from the vertical half-meter-sampled grade control drilling.

The oxide/fresh OK estimation was constrained within manually generated 0.1g/t Au mineralisation domains defined from the resource drillhole dataset and grade control data where available, and guided by a geological model.
Detailed statistical and geostatistical investigations have been completed on the captured estimation data set (1m composites for laterite and oxide). This includes exploration data analysis, boundary analysis and grade estimation trials. Appropriate high grade cuts were applied to the 1m composites for all domains in the laterite and oxide/fresh Resource estimates. A three-pass search strategy was employed for each estimate, with the oxide/fresh estimate also employing a high-grade restriction method to reduce the influence of highergrade data beyond a set distance.
Resource Classification
The laterite and oxide/fresh resource models use a classification scheme producing a resource code based on the number and location of gold composites used to estimate the gold grade of each block. This is based on the principle that larger numbers of composites, which are more evenly distributed within the search neighborhood, will provide a more reliable estimate.
For the laterites category 1 from the 3 pass search strategy is assigned as Measured and represents the grade control drilled portion of the deposit, category 2 is assigned as Indicated and category 3 as Inferred. This results in a geologically sensible classification whereby category 1 and 2 are surrounded by data in close proximity. Category 3 blocks may occur on the peripheries of drilling but are still related to drilling data within reasonable distances.
For the oxide/fresh estimation category 1 and 2 from the 3 pass search strategy are assigned as Indicated, and category 3 is assigned as Inferred. This results in a geologically sensible classification whereby category 1 and 2 are surrounded by data in close proximity. Category 3 blocks may occur on the peripheries of drilling but are still related to drilling data within reasonable distances. Other factors such as data quality, geological continuity and visual validation are also taken into account when applying the Resource classification.
Cut-off Grade
The cut-off grade of 0.4g/t for the stated Mineral Resource Estimate is determined from economic parameters and reflects the current and anticipated mining practices. The laterite and oxide/fresh Resource models are considered valid for reporting and open pit mine planning at a range of lower cut-off grades up to a lower cut-off grade of 0.8g/t.
Mining and Metallurgical Methods and Parameters and other modifying factors considered to date
The Mineral Resources utilise standardised operating parameters and a gold price of $2,000 per ounce to optimise an open pit shell. It assumes open cut mining practices with a moderate level of mining selectivity achieved during mining. It is also assumed that high quality grade control will be applied to ore/waste delineation processes. This is consistent with current mining practices at Moolart Well.
A gold recovery of 93% was used to determine Mineral Resources which has been based on potential recoveries indicated by metallurgical testwork in the Duketon area by Regis, production data and ongoing testwork to determine cyanidable gold recoveries.
Where metallurgical testwork and actual recovery data exists it will be applied in the relevant Ore Reserve but is not back applied to the Mineral Resource estimate.
Ore Reserve
Material Assumptions for Ore Reserve
The following material assumptions apply to the Ore Reserve:
- Gold price of $1,400 per ounce;
- Current operational capital and operating cost structure;

- Current operational mining and metallurgical performance; and
- Current operational geotechnical and hydrogeological performance.
Ore Reserve Classification
The classification of the Moolart Well Ore Reserve has been carried out in accordance with the recommendations of the JORC code 2012. It is based on the density of the drilling, estimation methodology, the orebody experience and the mining method employed.
All Proved and Probable Ore Reserves have been derived from Measured and Indicated resources respectively.
Mining Method
The mining method assumed in the Ore Reserve study is the same as that currently employed at the Moolart Well Gold Mine, which utilises drill and blast, excavator and truck open pit mining. The laterite pits are pre-stripped and then mined to the horizontal geological contacts. The oxide pits are designed to be developed in a series of progressive cutbacks.
Geotechnical and hydrogeological recommendations have been applied during pit optimisation and incorporated in design with ongoing reviews.
No mining loss or recovery factor has been considered in the estimation of the oxide/fresh Ore Reserve, and a 5% dilution has been applied in the estimation of the laterite Ore Reserve. This is considered consistent with the latest grade control and reconciliation data available from the existing operation and is consistent with the suitability of earthmoving equipment to the orebody type (low to moderate grade and wide mineralized zones).
Processing Method
The existing Moolart Well CIL Processing facility will be utilised to treat the Ore Reserve and a recovery factor of 90.5% has been assumed in the estimation of the Ore Reserve.
Full feasibility level metallurgical testwork was completed on the original Moolart Well resource prior to the construction and commissioning of the Moolart Well Processing Plant. The metallurgical results from the full scale Moolart Well Processing Plant have not displayed any significant differences to that predicted from the feasibility metallurgical testwork.
Cut-off Grade
Variable lower OK block cut-off grades have been applied in estimating the Ore Reserve. The lower cuts have been selected with consideration to mineability and cash operating margins. No upper cut has been applied to the Ore Reserve as this has been adequately dealt with in the Mineral Resource estimation stage.
Estimation Methodology
Refer to Mineral Resource section.
Material Modifying Factors
There are no material modifying factors that need to be highlighted with the Ore Reserve. Moolart Well is an operating mine. All regulatory leasing, approvals, licensing, agreements and current infrastructure are in place, which considers this estimation higher than that of a feasibility study.

APPENDIX 1: JORC COMPLIANT GOLD RESOURCES (INCLUSIVE OF RESERVES)
The following information is provided in accordance with Table 1 of Appendix 5A of the JORC Code 2012 – Section 1 (Sampling Techniques and Data), Section 2 (Reporting of Exploration Results), Section 3 (Estimation and Reporting) and Section 4 (Estimation and Reporting of Ore Reserves).
MOOLART WELL
JORC Code 2012 Edition – Table 1
Section 1 - Sampling Techniques and Data
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Samplingtechniques | Nature and quality of sampling (e.g. cut channels, random chips, orspecific specialised industry standard measurement tools appropriate tothe minerals under investigation, such as down hole gamma sondes, orhandheld XRF instruments, etc). These examples should not be taken aslimiting the broad meaning of sampling. | The Moolart Well deposit was sampled using Reverse Circulation (RC), Aircore(AC) and Diamond Drill Holes (DD) on a nominal 50m by 50m initial grid spacing.Infill drilling in the highest potential oxide/fresh areas has reduced the effectivespacing to25m by 25m. Shallow AC grade control drilling has been included forthe laterite estimation and is spaced at 12.5m by 12.5m. The oxide/fresh studyused the sampling from 5,012 holes (1,619 RC holes for 177,988 m, 3,252 ACholes for 224,543 m, 141 DD holes for 16,997 m) which were drilled mainly angled-60 degrees to grid west.The laterite study also used the vertical 12.5m by 12.5mgrade control holesmentioned above (an extra 12,023 AC GC holes for 122,683m). |
| Include reference to measures taken to ensure sample representivity andthe appropriate calibration of any measurement tools or systems used. | Pre 2009 drill hole collar locations were picked up using a Sokkia DGPS localisedto onsite datum (expected accuracy 300mm). 2009 onwards drill hole collarlocations were picked up by site-based authorised surveyors using Trimble RTKGPS. Downhole surveying was measured by the drilling contractors usingEastman Single Shot Camera for DD holes, Pathfinder survey instrument andEastman Single Shot Camera for RC holes and Eastman Single Shot Camera forthe AC holes. The surveys were completed every 30m down each drill hole.Manyof theAC holes did not have downhole surveys completed with the unsurveyedholes having a surface compass measurement applied (average depth of AC holesis 33m). | |
| Certified standards and blanks were inserted every 25th sample to assess theaccuracy and methodology of the external laboratories, and field duplicates wereinserted every 20th sample to assess the repeatability and variability of the goldmineralisation. Laboratory duplicates were also completed approximately every15th sample to assess the precision of the laboratory as well as the repeatability |

|---|---|---|
| and variability of the gold mineralisation. Results of the QAQC sampling wereconsidered acceptable for an Archaean gold deposit. | ||
| Aspects of the determination of mineralisation that are Material to thePublic Report. In cases where 'industry standard' work has been done thiswould be relatively simple (e.g. 'reverse circulationdrilling was used toobtain 1 m samples from which 3 kg was pulverised to produce a 30 gcharge for fire assay'). In other cases more explanation may be required,such as where there is coarse gold that has inherent sampling problems.Unusual commodities or mineralisation types (e.g. submarine nodules)may warrant disclosure of detailed information. | 1m AC samples were obtained by riffle splitter (1.5kg –2.0kg) and half metresamples via cone splitter for the laterite AC grade control (2kg –2.5kg) and 1m RCsamples were obtained by cone splitter (2.5kg –3.0kg), with all being utilised forlithology logging and assaying. Diamond core was used for geotechnical anddensity measurements as well as lithology logging and assaying. The core haspredominantly been sampled at 1m intervals, with some sampling on geologicalintervals. RC sampling prior to 2005 (256 drill holes) involved taking a speared4m field composite, with the 1m cone split sample only assayed for the 4m fieldcomposites returning a gold value above 0.1 g/t. AC sampling prior to 2005 (1,086drill holes) involved taking a speared 4m field composite, with any 4m fieldcomposites returning a gold value above 0.1 g/t being re-sampled via spearing the1m samples. | |
| All samples were dried, crushed and pulverised to get at least 85% passing 75µm.The laterite grade control samples were assayed via a 40g charge Aqua RegiaDigest with AAS finish, with the remainder of the assaying being completed byeither a 40g or 50g charge for fire assay analysis with AAS finish. Ultratrace,Amdel, Minanalytical, Aurum and Kalassay have all been used. | ||
| Drillingtechniques | Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast,auger, Bangka, sonic, etc) and details (e.g. core diameter, triple orstandard tube, depth of diamond tails, face-sampling bit or other type,whether core is oriented and if so, by what method, etc). | In the resource area AC drilling was completed with an 89mm diameter AC blade,RC drilling was completed with a 139mm diameter face sampling hammer and DDwas completed at PQ and HQ3 sized core. Core orientations were completedusing chalk and spearfor PQ and REFLEX ACT III toolfor HQ3. |
| Drill samplerecovery | Method of recording and assessing core and chip sample recoveriesandresults assessed. | Diamond core recovery was logged and recorded in the database, with nosignificant core loss issues occurring in the mineralised zones. Average corerecovery is 99% for the mineralised zones. |
| RC recovery was visually assessed, with recovery being excellent except in somewet intervals which are recorded on logs. <1% of the overall mineralised zoneshave been recorded as wet. | ||
| Measures taken to maximise sample recovery and ensure representativenature of the samples. | Diamond core was reconstructed for orientation and marking on V-channelorientation racks, and depths are checked and measured against those marked bythe drilling contractors on core blocks. | |
| RC samples were visually checked for recovery, moisture and contamination. Thedrilling contractors utilised a cyclone and splitter to provide uniform sample size,and these were cleaned routinely (cleaned at the end of each rod and more |

| frequently in wet conditions). A booster was also used in conjunction with the RCdrill rig to ensure dry samples are achieved. | ||
| Whether a relationship exists between sample recovery and grade andwhether sample bias may have occurred due to preferential loss/gain offine/coarse material. | Sample recoveries for diamond and RC holes are high, especially within themineralised zones. No significant bias is expected. | |
| Logging | Whether core and chip samples have been geologically and geotechnicallylogged to a level of detail to support appropriate Mineral Resourceestimation, mining studies and metallurgical studies. | Lithology, alteration, veining, mineralisation, recovery, RQD, density andgeotechnical/structure were all logged for the diamond core and saved in thedatabase. Core photographs were taken on whole core, and all half core isretained in a core yard for future reference. |
| Lithology, alteration, veining, mineralisation and magnetic susceptibility werelogged from the RC chips and saved in the database. Chips from every intervalare also placed in chip trays and stored in a designatedbuilding at site for futurereference. | ||
| Whether logging is qualitative or quantitative in nature. Core (or costean,channel, etc) photography. | All logging is qualitative except for density and magnetic susceptibility. Both wetand dry core photography was completed prior to sampling. | |
| The total length and percentage of the relevant intersections logged. | All drill holes are logged in full. | |
| Sub-samplingtechniques andsamplepreparation | If core, whether cut or sawn and whether quarter, half or all core taken. | The majority of the core was cut in half onsite with a core saw, with the half coresamples for analysis collected from the same side in all cases. |
| If non-core, whether riffled, tube sampled, rotary split, etc and whethersampled wet or dry. | The RC drilling utilised a cyclone and cone splitter to consistently produce 2.5kgto 3.0kg dry samples. Sampling for the majority of the AC drilling utilised a cycloneand single tier riffle splitter to consistently produce 1.5kg to 2.0kg dry samples. Insome rare cases when the sample was wet, a spear sample of the sample intervalwas used. | |
| For all sample types, the nature, quality and appropriateness of the samplepreparation technique. | Samples are dried, crushed to 10mm, and then pulverised to 85% passing 75µm(80% passing 75µm for the historical drilling). This is considered acceptable foran Archaean gold deposit. | |
| Quality control procedures adopted for all sub-sampling stages tomaximise representivity of samples. | Field duplicates were inserted every 20th sample to assess the repeatability andvariability of the gold mineralisation. Laboratory assay duplicates were alsocompleted roughly every 15th sample to assess the repeatability and variability ofthe gold mineralisation. |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Measures taken to ensure that the sampling is representative of the in situmaterial collected, including for instance results for field duplicate/secondhalf sampling. | Field RC duplicates were taken at the rig from a second chute on the cone splitterallowing for the duplicate and main sample to be the same size and samplingtechnique. Field duplicates for the AC drilling were taken at the rig by spearing theriffle split non-sample fraction, and by the second chute on the cone splitter for thelaterite AC grade control. Diamond core field duplicates were taken by cutting thehalf core sample into two quarters. Field duplicates were taken every 20th sample.The results of the field duplicates show an acceptable level of repeatability for anArchaean gold deposit. | |
| Laboratory duplicates (sample preparation split) were also completed roughlyevery 15th sample to assess the analytical precision of the laboratory. Acceptablelevel of repeatability and precision was noted for all laboratories. | ||
| 60 of the diamond holes are close enough to RC/AC holes to be considered twinholes. These "twin" DD holes support the location and size of the mineralisationzones, as well as the tenor of the intercepts. The average gold grade of themineralised intercepts shows no bias towards either DD or percussion drillingmethods and is broadly split between being higher for diamond and the RC/ACdrilling. The differences between the drill "twins" is consistent with the high levelsof short scale variability common in most Archaean gold mineralisation systems. | ||
| Whether sample sizes are appropriate to the grain size of the materialbeing sampled. | Sample sizes (1.5kg to 3kg) at Moolart Well are considered to be a sufficient sizeto accurately represent the gold mineralisation based on the mineralisation style(hypogene associated with shearing and supergene enrichment), the width andcontinuity of the intersections, the sampling methodology, the coarse goldvariability and the assay ranges for the gold. | |

| Nature of quality control procedures adopted (e.g. standards, blanks,duplicates, external laboratory checks) and whether acceptable levels ofaccuracy (ie lack of bias) and precision have been established. | Certified Reference Material (CRM or standards) and blanks were inserted every25th sample to assess the assaying accuracy of the external laboratories. Fieldduplicates were inserted every 20th sample to assess the repeatabilityfrom thefield and variability of the gold mineralisation. Laboratory duplicates were alsocompleted approximately every 15th sample to assess the precision of assaying. | |
| Evaluation of both the resource definition drilling submitted standards, and theinternal laboratory quality control data, indicates assaying to be accurate andwithout significant drift for significant time periods. Excluding obvious errors, thevast majority of the CRM assaying report shows an overall mean bias of less than5% with noconsistent positive or negative bias noted.

| Discuss any adjustment to assay data. | Any samples not assayed (i.e. destroyed in processing, listed not received) havehad the assay value converted to a -9 in the database. Any samples assayedbelow detection limit (0.01 ppm Au) have been converted to 0.005 ppm (halfdetection limit) in the database. | |
| Location of datapoints | Accuracy and quality of surveys used to locate drill holes (collar and downhole surveys), trenches, mine workings and other locations used in MineralResource estimation. | Pre 2009 Regis drill hole collar locations were picked up using a Sokkia DGPSlocalised to onsite datum (expected accuracy 300mm). 2009 onwards Regis drillhole collar locations were picked up by site-based authorised surveyors usingTrimble RTK GPS, calibrated to a base station (expected accuracy of 20mm). |
| Downhole surveying (magnetic azimuth and dip of the drill hole) was measured bythe drilling contractors in conjunction with Regis personnel using Reflex EastmanSingle Shot for DD holes, Pathfinder survey instrument and Eastman Single ShotCamera for RC holes and Eastman Single Shot Camera for the AC holes. Thesurveys were completed every 30m down each DD and RC drill hole.SomeACholes did not havedownhole surveys completed with the unsurveyed holes havinga surface compass measurement applied (average depth of resourceAC holes is33m).

| Whether sample compositing has been applied. | RC sampling prior to 2005 (256 drill holes) involved taking a speared 4m fieldcomposite, with the four 1m cone split samples only assayed for any fieldcomposites returning a gold value above 0.1 g/t. AC sampling prior to 2005 (1,086drill holes) involved taking a speared 4m field composite, with any 4m fieldcomposites returning a gold value above 0.1 g/t being re-sampled via spearing the1m samples. From 2005 no further field compositing has taken place. | |
| Orientation ofdata in relationto geologicalstructure | Whether the orientation of sampling achieves unbiased sampling ofpossible structures and the extent to which this is known, considering thedeposit type. | The drilling is predominantly orientated west (grid 270°) with a 60 degree dip, whichis roughly perpendicular to both the strike and dip of the oxide/fresh mineralisation,therefore ensuring intercepts are close to true-width. The AC laterite grade controldrilling is all vertical and therefore perpendicular to the sub-horizontal lateritemineralisation. Project to date mining confirms this is thecase. |
| If the relationship between the drilling orientation and the orientation of keymineralised structures is considered to have introduced a sampling bias,this should be assessed and reported if material. | Diamond drilling, mining and reconciliation confirm that drilling orientation has notintroduced any bias regarding the orientation of the mineralised domains. | |
| Sample security | The measures taken to ensure sample security. | Samples are securely sealed and stored onsite, until delivery to Perthvia contractfreightTransport, who then deliver the samples directly to the laboratory. Samplesubmission forms are sent with the samples as well as emailed to the laboratory,and are used to keep track of the sample batches. |
| Audits orreviews | The results of any audits or reviews of sampling techniques and data. | A site visit was completed in 2007 (Golder) to review sampling procedures, and aQAQC/data audit was completed in 2007 (Golder) which both concluded thesampling/data to be at industry standard, and of sufficient quality to carry out aMineral Resource estimation.

| Data validation procedures used. | Following importation, the data goes through a series of digital and visual checks forduplication and non-conformity, followed by manual validation by a company geologistand database administrator. | |
| Site visits | Comment on any site visits undertaken by the Competent Person and theoutcome of those visits. | The competent personhas made numerous site visits to Moolart Well. No issues havebeen noted and all procedures were considered to be of industry standard. |
| In addition to the above site visit, all exploration and resource development drillingprogrammes are subject to review by experienced senior Regis technical staff. Thesereviews have been completed from the commencement of drilling and continue to thepresent. | ||
| If no site visits have been undertaken indicate why this is the case. | Not applicable. | |
| Geologicalinterpretation | Confidence in (or conversely, the uncertainty of) the geologicalinterpretation of the mineral deposit. | The confidence in the geological interpretation is high. Locally at Moolart Well thegeology consists of a series of dolerite and diorite intrusions, minor sedimentarypackages and ultramafic volcanics all overlaid by a moderately thick transported unit.The area has undergone deep weathering which has propagated deeper in shear zones.The basement geology dips moderately to the east. Quartz-sulphide veining hosts thehypogene gold mineralisation. The transported cover (laterite) contains the lateritesupergene ore which is a 4m thick horizontal zone of high goethite/hematite content.Mining to date supports the original geological constraints and this model has beenupdated with the knowledge gained during the mining at Moolart Well. |
| Nature of the data used and of any assumptions made. | The geological data used to construct the geological model includes regional anddetailed surface mapping, in pit wall mapping, and logging of RC/diamond core drilling,and to a lesser degree multi-element assaying. | |
| The effect, if any, of alternative interpretations on Mineral Resourceestimation. | The geology of the deposit is relatively simple, and the interpretation is consideredrobust. There is no apparent alternative to the interpretation in the company's opinion. | |

| The factors affecting continuity both of grade and geology. | A broad zone of shearing and quartz-sulphide veining localises and controls the goldmineralisation in the more hypogene-controlled transitional and fresh horizons. In theoxide horizon, the gold mineralisation is also influenced by the redox fronts, where it issometimes spread in a more flat-lying manner in a westerly direction. In the overlyinglaterite horizon, the gold mineralisation is restricted to a 4m to 6m thick pisolitic ore zone. | |
| Dimensions | The extent and variability of the Mineral Resource expressed as length(along strike or otherwise), plan width, and depth below surface to theupper and lower limits of the Mineral Resource. | The approximate dimensions of the deposit are 5,000m along strike (N-S), 700m across(E-W) for both laterite and oxide/fresh. The laterite mineralisation extends 25mmaximum from surface, and the oxide/fresh mineralisation has been drilled up to 430mbelow surface. |
| Estimation andmodelingtechniques | The nature and appropriateness of the estimation technique(s) applied andkey assumptions, including treatment of extreme grade values, domaining,interpolation parameters and maximum distance of extrapolation from datapoints. If a computer assisted estimation method was chosen include adescription of computer software and parameters used. | Laterite: The laterite Resource estimate has been generated via Ordinary Kriging (OK)with no change of support. The OK estimation was constrained within a 0.4g/t Aumineralisation zone interpretation (topand bottom of ore) accurately defined from thevertical half-meter-sampled grade control drilling, created in Surpac. OK is consideredan appropriate grade estimation method for the laterite mineralisation at Moolart Wellgiven current drilling density and mining history/reconciliation, which has allowed thedevelopment of robust and high confidence mineralisation constraints. |
| The grade estimate is based on 1m down-the-hole composites created in Surpac eachlocated by their mid-point co-ordinates and assigned a length weighted average goldgrade. The composite length of 1m was chosen because it is a multiple of the mostcommon non-grade-control sampling interval (1.0 metre), whilst still giving enoughvertical detail (perpendicular to mineralisation) to provide an accurate estimation of thethin sub-horizontal blanket. High grade cuts (as described below) have been applied tocomposites to limit the influence of higher grade data. | ||

| The grade estimate is based on 1m down-the-hole composites of the resource datasetcreated in Surpac each located by their mid-point co-ordinates and assigned a lengthweighted average gold grade. The composite length of 1m was chosen because it is amultiple of the most common l sampling interval (1.0 metre), and is also an appropriatechoice for the kriging ofgold into the model blocks assuming open pit mining willcontinue to occur on approximately 2.5 metre benches. A high-grade populationidentified through statistical analysis was first flagged in the model, allowing a high-graderestriction to be used. This involves those flagged blocks being estimated by the totaldomain composite file cut to a higher upper-cut, with the remaining portions of thedomain being estimated with total domain composite file cut to a lower uppercut. Thehigh-grade restriction andhigh grade cuts (as described below) have been applied tocomposites to limit the influence of higher grade data. | ||

| Discuss assumptions for bulk density estimates used in the evaluationprocess of the different materials. | Little spatial variation is noted for the bulk density data within lithological and weatheringboundaries and therefore an average bulk density has been assigned for tonnagereporting based on weathering coding. | |
| Classification | The basis for the classification of the Mineral Resources into varyingconfidence categories. | The laterite and oxide/fresh Resource models use a classification scheme producing aresource code based on the number and location of gold composites used to estimatethegold grade of each block. This is based on the principle that larger numbers ofcomposites, which are more evenly distributed within the search neighbourhood, willprovide a more reliable estimate. |
| Laterite: The strategy adopted in the current study uses category 1 from the 3 passsearch strategy as Measured and represents the grade control drilled portion of themineralisation, category 2 as Indicated and category 3 as Inferred. This results in ageologically sensible classification whereby category 1 and 2 are surrounded by data inclose proximity. Category 3 blocks may occur on the peripheries of drilling but are stillrelated to drilling data within reasonable distances. | ||
| Oxide/fresh: The strategy adopted in the current study uses category 1 and 2 from the3 pass search strategy as Indicated, and category 3 as Inferred. This results in ageologically sensible classification whereby category 1 and 2 are surrounded by data inclose proximity. Category 3 blocks may occur on the peripheries of drilling but are stillrelated to drilling data within reasonable distances. |

Section 1 - Sampling Techniques and Data
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Samplingtechniques | Nature and quality of sampling (e.g. cut channels, random chips, orspecific specialised industry standard measurement tools appropriate tothe minerals under investigation, such as down hole gamma sondes, orhandheld XRF instruments, etc). These examples should not be taken aslimiting the broad meaning of sampling. | The Garden Well deposit was sampled using Reverse Circulation (RC), Aircore(AC) and Diamond Drill Holes (DD) on a nominal 40m by 40m grid spacing. Thecurrent study used the sampling from 977holes for 164,007m (611RC holes for91,986m, 230 AC holes for 20,943 m, 118 DD holes for 44,389 m and 18 RC precollared diamond holes for 6,689m), which were drilled mainly angled -60 degreesto grid west. |
| Include reference to measures taken to ensure sample representivity andthe appropriate calibration of any measurement tools or systems used. | Regis drill hole collar locations were picked up by site-based authorised surveyorsusing Trimble RTK GPS. Downhole surveying was measured by the drillingcontractors using Reflex EZ-Shot Downhole Survey Instrument for DD holes,Pathfinder survey instrument for RC holes and Eastman Single Shot Camera forthe AC holes. The surveys were completed every 30m down each drill hole. | |
| Certified standards and blanks were inserted every 25th sample to assess theaccuracy and methodology of the external laboratories, and field duplicates wereinserted every 20th sample to assess the repeatability and variability of the goldmineralisation. Laboratory duplicates were also completed approximately every15th sample to assess the precision of the laboratory as well as the repeatabilityand variability of the gold mineralisation. Results of the QAQC sampling wereconsidered acceptable for an Archaean gold deposit. | ||
| Aspects of the determination ofmineralisation that are Material to thePublic Report. In cases where 'industry standard' work has been done thiswould be relatively simple (e.g. 'reverse circulation drilling was used toobtain 1 m samples from which 3 kg was pulverised to produce a 30 gcharge for fire assay'). In other cases more explanation may be required,such as where there is coarse gold that has inherent sampling problems.Unusual commodities or mineralisation types (e.g. submarine nodules)may warrant disclosure of detailed information. | Beneath the transported horizon (waste overburden, considered devoid of goldmineralisation and regularly not sampled) 1m AC samples were obtained by rifflesplitter (1.5kg –2.0kg) and 1m RC samples were obtained by cone splitter (2.5kg–3.0kg),with both being utilised for lithology logging and assaying. Diamond corewas used for geotechnical and density measurements as well as lithology loggingand assaying. HQ diameter diamond coring has been used through chert and hasbeen whole core sampled, NQ2 diameter coring has been used through ultramaficand shale and half core sampled with half of the core being kept in storage. Thecore has predominantly been sampled at 1m intervals, with some sampling ongeological intervals (0.2m –1.0m). | |
| All samples were dried, crushed and pulverised to get 85% passing 75µm, anddepending on the external laboratory either a 30g (31% of assays), 40g (55% of |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| assays) or 50g (14% of assays) charge for fire assay analysis with AAS finish.Ultratrace, Kalassay, Minanalytical and SGS have all been used. | ||
| Drillingtechniques | Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast,auger, Bangka, sonic, etc) and details (e.g. core diameter, triple orstandard tube, depth of diamond tails, face-sampling bit or other type,whether core is oriented and if so, by what method, etc). | In the resource area AC drilling with an 89mm diameter AC blade accounts for13% of the drilling metres with an average hole depth of 91m. RC drilling with a139mm diameter face sampling hammer accounts for 56% of the drilling meters inthe resource area with an average hole depth of 151m. Diamond drillingcomprising HQ triple tube and NQ2 sized core accounts for 27% of the drillingmeters in the resource area with an average hole depth of 376.2m. RC Pre-collardrill holes with NQ2 diamond tails account for 4% of the drilling meters in theresource area with an average hole depth of 371.6m. Core orientations werecompleted using Reflex Act 2 and Reflex Act 3 RD orientation tools at the end ofeach run. |
| Drill samplerecovery | Method of recording and assessing core and chip sample recoveries andresults assessed. | Diamond core recovery was logged and recorded in the database, with nosignificant core loss issues occurring in the mineralised zones. Average corerecovery is 96% for the mineralised zones. |
| RC and AC recovery were visually assessed, with recovery being excellent exceptin some wet intervals which are recorded on logs. 1.1% of the overall mineralisedzones have been recorded as wet. | ||
| Measures taken to maximise sample recovery and ensure representativenature of the samples. | Diamond core was reconstructed for orientation and marking on V-channelorientation racks, and depths are checked and measured against those marked bythe drilling contractors on core blocks. | |
| RC samples were visually checked for recovery, moisture and contamination. Thedrilling contractor utilised a cyclone and splitter to provide uniform sample size,and these were cleaned routinely (cleaned at the end of each rod and morefrequently in wet conditions). A booster was also used in conjunction with the RCdrill rig to ensure dry samples are achieved. | ||
| Whether a relationship exists between sample recovery and grade andwhether sample bias may have occurred due to preferential loss/gain offine/coarse material. | Sample recoveries for diamond and RC holes are high, especially within themineralised zones. No significant bias is expectedalthough no recovery and gradecorrelation study was completed. | |
| Logging | Whether core and chip samples have been geologically and geotechnicallylogged to a level of detail to support appropriate Mineral Resourceestimation, mining studies and metallurgical studies. | Lithology, alteration, veining, mineralisation, magnetic susceptibility, recovery,RQD, density and geotechnicalinformationwere all logged for the diamond coreand saved in the database. Core photographs were taken, and all half core isretained in a core yard for future reference. |
| Lithology, alteration, veining, mineralisation andon some holesmagneticsusceptibility were logged from the RC chips and saved in the database. Chips |

| Whether logging is qualitative or quantitative in nature. Core (or costean,channel, etc) photography. | All logging is qualitative except for density and magnetic susceptibility. Both wetand dry core photography wascompleted prior to sampling. | |
| The total length and percentage of the relevant intersections logged. | All drill holes are logged in full. | |
| Sub-samplingtechniques andsamplepreparation | If core, whether cut or sawn and whether quarter, half or all core taken. | The majority of the core was cut in half onsite (NQ2) with a core saw, with the halfcore samples for analysis collected from the same side in all cases. Corecontaining lithology chert proved to be very difficult to cut by core saw thereforewhole core sampling was utilised for the chert to quicken the process. Whole coresampling as opposed to interval sampling was chosen to eliminate any intervalsampling bias. |
| If non-core, whether riffled, tube sampled, rotary split, etc and whethersampled wet or dry. | The RC drilling utilised a cycloneand cone splitter to consistently produce 2.5kgto 3.0kg dry samples. The AC drilling utilised a cyclone and single tier riffle splitterto consistently produce 1.5kg to 2.0kg dry samples. | |
| For all sample types, the nature, quality and appropriateness of the samplepreparation technique. | Samples are dried, crushed to 10mm, and then pulverised to 85% passing 75µm.This is considered acceptable for an Archaean gold deposit. | |
| Quality control procedures adopted for all sub-sampling stages tomaximise representivity of samples. | Field duplicates were inserted every 20th sample to assess the repeatability andvariability of the gold mineralisation. Laboratory duplicates were also completedroughly every 15th sample to assess the repeatability and variability of the goldmineralisation. | |
| Measures taken to ensure that the sampling is representative of the in situmaterial collected, including for instance results for field duplicate/secondhalf sampling. | Field RC duplicates were taken at the rig from a second chute on the cone splitterallowing for the duplicate and main sample to be the same size, field AC duplicateswere taken at the rig by spearing the riffle split non-sample fraction and diamondcore field duplicates were taken by cutting the half core sample into two quarters.Field duplicates are taken every 20th sample. Laboratory duplicates (samplepreparation split) were also completed roughly every 15th sample. Two diamondholes were drilled to twin RC holes and supported the location of the mineralisedzone, with the average gold grade being higher for diamond in one case, andhigher for RC in the other, further demonstrating the nugget effect consistent withArchaean gold mineralisation. | |
| Whether sample sizes are appropriate to the grain size ofthe materialbeing sampled. | Sample sizes (1.5kg to 3kg) at Garden Well are considered to be a sufficient sizeto accurately represent the gold mineralisation based on the mineralisation style(hypogene associated with shearing and supergene enrichment), the width and |

| Field duplicates have routinely been collected to ensure monitoring of the subsampling quality.Acceptable precision and accuracy is noted in the fieldduplicates albeit the precision is marginally acceptable and consistent with acoarse gold Archaean gold deposit. | ||
| Quality of assaydata andlaboratory tests | The nature, quality and appropriateness of the assaying and laboratoryprocedures used and whether the technique is considered partial or total. | All gold assaying was completed by commerciallaboratories (Ultratrace, Kalassay,SGS and MinAnalytical) using either a 30g, 40g or 50g charge for fire assayanalysis with AAS finish. This technique is industry standard for gold andconsidered appropriate. |
| For geophysical tools, spectrometers, handheld XRF instruments, etc, theparameters used in determining the analysis including instrument makeand model, reading times, calibrations factors applied and their derivation,etc. | A handheld magnetic susceptibility meter (KT-10) was used to measure magneticsusceptibility for some RC and diamond samples, and is recorded in the loggingspread sheets. The results were not used inthe delineation of mineralised zonesor lithologies. | |
| Nature of quality control procedures adopted (e.g. standards, blanks,duplicates, external laboratory checks) and whether acceptable levels ofaccuracy (ie lack of bias) and precision have been established. | Certified Reference Material (CRM or standards) and blanks were inserted every25th sample to assess the assaying accuracy of the external laboratories. Fieldduplicates were inserted every 20th sample to assess the repeatability from thefield andvariability of the gold mineralisation. Laboratory duplicates were alsocompleted approximately every 15th sample to assess the precision of assaying. | |
| Evaluation of both the Regis submitted standards, and the internal laboratoryquality control data, indicates assaying to be accurate and without significant driftfor significant time periods. Excluding obvious errors, the vast majority of the CRMassaying report shows an overall mean bias of less than 5% with no consistentpositive or negative bias noted.Duplicate assaying shows high levels ofcorrelation and no apparent bias between the duplicate pairs. Field duplicatesample show marginally acceptable levels of correlation and no relative bias. | ||
| Results of the QAQC sampling were considered acceptable for an Archaean golddeposit. Substantial focus has been given to ensuring sampling procedures metindustry best practise to ensure acceptable levels of accuracy and precision wereachieved in a coarse gold environment. | ||
| Verification ofsampling andassaying | The verification of significant intersections by either independent oralternative company personnel. | No independent personnel have visually inspected the significant intersections incore or RC chips. Numerous highly qualified and experienced company personnelfrom exploration and production positions have visually inspected the significantintersections in core and RC chips. |

| The use of twinned holes. | Two diamond holes were drilled to twin RC holes and supported the location(width) of the mineralised zone, with the average gold grade being higher fordiamond in one case, and higher for RC in the other, further demonstrating thenugget effect consistent with Archaean gold mineralisation. | |
| Documentation of primary data, data entry procedures, data verification,data storage (physical and electronic) protocols. | All geological and field data is entered into excel spreadsheets with lookup tablesand fixed formatting (and protected from modification) thus only allowing data tobe entered using the Regis geological code system and sample protocol. Data isthen emailed to the Regis database administrator for validation and importationinto a SQL database using Datashed. | |
| Discuss any adjustment to assay data. | Any samples not assayed (i.e. destroyed in processing, listed not received) havehad the assay value converted to a -9 in the database. Any samples assayedbelow detection limit (0.01 ppm Au) have been converted to 0.005 ppm (halfdetection limit) in the database. | |
| Location of datapoints | Accuracy and quality of surveys used to locate drill holes (collar and downhole surveys), trenches, mine workings and other locations used in MineralResource estimation. | Pre 2012 Regis drill hole collar locations were picked up using a Sokkia DGPSlocalised to onsite datum (expected accuracy 300mm). 2012 onwards Regis drillhole collar locations were picked up by site-based authorized surveyors usingTrimble RTK GPS, calibrated to a base station (expected accuracy of 20mm). |
| Downhole surveying (magnetic azimuth and dip of the drill hole) was measured bythe drilling contractors in conjunction with Regis personnel using Reflex EZ-ShotDownhole Survey Instrument for DD holes, Pathfinder survey instrument for RCholes and Eastman Single Shot Camera for the AC holes. The surveys werecompleted every 30m down each drill hole, except for the AC holes, which weresurveyed at the collar and then 80m down the hole.

The gold of the Garden Well Deposit occurs as supergenemineralisation within upper Archaean regolith and as hypogene mineralisation infresh rock. No significant amounts of gold occur in the transported Quaternary claysequence. The gold is associated with intensely sheared and folded ultramaficand shale units that have been hydrothermally altered to a silica-carbonatefuchsite-chlorite-pyrite-arsenopyrite assemblage, and underlying chert units.

| If no site visits have been undertaken indicate why this is the case. | Not applicable. | |
| Geologicalinterpretation | Confidence in (or conversely, the uncertainty of) the geologicalinterpretation of the mineral deposit. | The confidence in the geological interpretation is high. Locally at Garden Well theshear zone is located on the footwall side of an east dipping sedimentary packageunderlain by an ultramafic unit. The shear zone is several hundred metres wideand dips moderately to steeply east and is sub-parallel to the sedimentary contact.The intense shearing along the sedimentary contact is contained within a mixedultramafic-sedimentary package that is the host unit for the gold mineralisation. Inthe southern extension the mineralisation takes a slight jog to the east and ispredominantly within a thin shale horizon along the hanging wall of the sedimentarypackage, and also within a chert unit that overlies the sedimentary package.Mining to date supports the original geological constraints and this model has beenupdated with the knowledge gained during the mining at Garden Well. |
| Nature of the data used and of any assumptions made. | The geological data used to construct the geological model includes regional anddetailed surface mapping, in pit wall mapping, and logging of AC/RC/diamond coredrilling, and to a lesser degree multi-element assaying, has been applied ingenerating the mineralisation constraints incorporating the geological controls. Anominal 0.1g/t Au lower cut-off grade was applied to the mineralisation modelgeneration. Five broad mineralisation zones have been defined that represent a |

| The effect, if any, of alternative interpretations on Mineral Resourceestimation. | The geology and interpretation of the deposit is considered robust. There is noapparent alternative to the interpretation in the company's opinion. | |
| The use of geology in guiding and controlling Mineral Resource estimation. | A model of the lithology and weathering was generated prior to the mineralisationdomain interpretation commencing, and has been updated with the logging ofgrade control drilling in this 2015 Resource update. The mineralisation geometryhas a very strong relationship with the lithological interpretation and structure,especially in transitional and fresh material. In weathered zones the redox frontsand base of alluvium also become important factors in mineralisation controls andhave been applied to guide the mineralisation zone interpretation. | |
| The factors affecting continuity both of grade and geology. | A broad zone of shearing localises and controls the gold mineralisation in the morehypogene-controlled transitional and fresh horizons. In the oxide horizon, the goldmineralisation is also influenced by the redox fronts, where it is sometimes spreadin a more flat-lying manner in a westerly direction. | |
| Dimensions | The extent and variability of the Mineral Resource expressed as length(along strike or otherwise), plan width, and depth below surface to theupper and lower limits of the Mineral Resource. | The approximate dimensions of the deposit are 2,100m along strike (N-S), 600macross (E-W), and 500m below surface. |
| Estimation andmodelingtechniques | The nature and appropriateness of the estimation technique(s) applied andkey assumptions, including treatment of extreme grade values, domaining,interpolation parameters and maximum distance of extrapolation from datapoints. If a computer assisted estimation method was chosen include adescription of computer software and parameters used. | MPR used the method of Multiple Indicator Kriging (MIK) with block supportadjustment to estimate gold resources into blocks with dimensions of 20m (east)by 40m (north) by 5m (elevation). MIK of gold grades used indicator variographybased on the two metre resource composite sample grades. Gold grade continuitywas characterised by indicator variograms at 14 indicator thresholds spanning theglobal range of grades. A block support adjustment was used to estimate therecoverable gold resources at Garden Well. The shape of the local block goldgrade distribution has been assumed lognormal and an additional adjustment forthe "Information Effect" has been applied to arrive at the final Resource estimates. |
| MIK was used as the preferred method for estimation of gold resources at GardenWell as the approach has been demonstrated to work well in a large number ofdeposits of diverse geological styles. The gold mineralisation seen at Garden Wellis typical of that seen in most structurally controlled gold deposits and where theMIK method has been found to be of most benefit. | ||

| Discussion of basis for using or not using grade cutting or capping. | A combination of outlier high grade composites being ignored for each sub-domainfor the generation of the indicator statistics, and selection of the median instead ofmean for the highest indicator threshold were used to guard against a few highergrades within the population from having a disproportional influence on the goldestimation. | |
| The process of validation, the checking process used, the comparison ofmodel data to drill hole data, and use of reconciliation data if available. | The grade estimate was checked against the input resource developmentdrilling/composite data both visually on section (cross and long section) and in planat the time of creation. The MP3 grade control study described above was anotherform of validation used, where the agreement between the predicted MIKResource and MP3 GC model is good. To investigate potential impact on miningschedules the Resource estimate and GC model have been compared onquarterly basis since the commencement of ore mining in the Garden Well.

Section 1 - Sampling Techniques and Data
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Samplingtechniques | Nature and quality of sampling (e.g. cut channels, random chips, orspecific specialised industry standard measurement tools appropriate tothe minerals under investigation, such as down hole gamma sondes, orhandheld XRF instruments, etc). These examples should not be taken aslimiting the broad meaning of sampling. | The Rosemont deposit was sampled using Reverse Circulation(RC), Aircore (AC)and Diamond Drill Holes (DD) on a nominal 40m by 40m initial grid spacing. Infilldrilling in the main zone has reduced the effective spacing between holes to 10 to20 metres (east) by 20 metres (north) to a depth of 100 metres from surface. Infilldrilling in the north zone has reduced the effective spacing between holes to 20metres (east) by 20 metres (north) to a depth of 200 metres from surface. Thecurrent study used the sampling from 1,299holes for 176,377m (1,151RC holesfor138,402m, 14 AC holes for 443 m, 10 DD holes for 1,345 m and 124RC precollared diamond holes for 36,186m, whichwere drilled bothangled -60 degreesto mine grid east and mine grid west. The additional drillingcarried out in 2016amountsto 36RC holes for 1,941metres and 6 RC/DC holes for 2,043m of drilling. |
| Include reference to measures taken to ensure sample representivity andthe appropriate calibration of any measurement tools or systems used. | Regis drill hole collar locations were picked up bysite-based authorised surveyorsusing Trimble RTK GPS. Downhole surveying was measured by the drillingcontractors using Reflex EZ-Shot Downhole Survey Instrument for DD and RCholes. The surveys were completed every 30m down each drill hole. | |
| Historical drill hole collar location pick up method is unknown. Collar locationswere viewed against a surface DTM created by photogrammetry and against Regisdrill hole collars. 30% of the historical collar locations were deemed to beinaccurate for RL and outby an average of 3.19m. These collars were draped tothe surface DTM before use in the Resource estimate.Post-draping themineralisation, lithological logging and weathering logging conformed to theaccurately picked up drill holes. Downhole survey method is also not recorded forthe historical drilling. 40% of the holes only have planned dip and azimuthrecorded. These holes without proper dip and azimuth are generally shallower(average 59m) and therefore are unlikely to deviate much,as the drill holes thathave downhole survey generally have minimal deviation, especially at theshallower depths. | ||
| Regis drill hole sampling had certified standards and blanks inserted every 25thsample to assess the accuracy and methodology of the external laboratories, andfield duplicates were inserted every 20th sample to assess the repeatability andvariability of the gold mineralisation.

| Historical drill hole sampling had field duplicates inserted every 20th sample for allsamples that returned>1g/t Au to assess the repeatability and variability of thegold mineralisation. ALS and Analabs tested standards and blanks as well asassay duplicates to assess the precision of the laboratory as well as therepeatability and variability of the gold mineralisation. Field composite values werecompared to the single metre re-split values. Screen fire assay and fire assayresults were compared as were LeachWell and fire assay. Some mineralised coresamples were also sent to other laboratories for umpire assaying. Results of allthe historical QAQC sampling were considered acceptable for an Archaean golddeposit. | ||
| Aspects of the determination of mineralisation that are Material to thePublic Report. In cases where 'industry standard' work has been donethiswould be relatively simple (e.g. 'reverse circulation drilling was used toobtain 1 m samples from which 3 kg was pulverised to produce a 30 gcharge for fire assay'). In other cases more explanation may be required,such as where there is coarse gold that has inherent sampling problems.Unusual commodities or mineralisation types (e.g. submarine nodules)may warrant disclosure of detailed information. | For the Regis managed drilling 1m RC samples were obtained by cone splitter(2.5kg –3.0kg) and wereutilised for lithology logging and assaying. Diamond corewas used for geotechnical and density measurements as well as lithology loggingand assaying. HQ diameter triple tube diamond coring was drilled as the holeswere used for bulk density and geotechnical measurements as well as assaying.Half of the core was sampled with half of the core being kept in storage. The corehas predominantly been sampled at 1m intervals, with some sampling ongeological intervals (0.2m –1.0m). | |
| The Regis managed drilling samples were dried, crushed and pulverised to get85% passing 75µm and were predominantly Fire Assayed using a 50g charge(MinAnalytical, Kalassay, Aurum and SGS), with some Fire Assay with a 40gcharge (Kalassay). | ||
| For historical drilling the samples were dried, crushed and pulverised to get 80%passing 75µm and were predominantly Fire Assayed using a 50g charge (ALS andAnalabs), with the 4m field composites being assayed via Aqua Regia on 50g pulpsusing an AAS finish. | ||
| Drillingtechniques | Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast,auger, Bangka, sonic, etc) and details (e.g. core diameter, triple orstandard tube, depth of diamond tails, face-sampling bit or other type,whether core is oriented and if so, by whatmethod, etc). | In the resource area AC drilling with an 89mm diameter AC blade accounts for<1% of the drilling metres with an average hole depth of 31.6m, RC drillingcompleted with a 139mm diameter face sampling hammer accounts for 78% of thedrilling meters in the resource areawith an average hole depth of 120.2m.Diamond drilling (comprising HQ triple tube for the Regis managed drilling andunknown for the historical drilling) accounts for 1% of the drilling meters in theresource area with an averagehole depth of 134.5m. RC/DD drill holes accountfor 21% of the drilling metres with an average hole depth of 291.8m. Coreorientations were completed using Reflex Act 2 and Reflex Act 3 RD orientation |

| Drill samplerecovery | Method of recording and assessing core and chip sample recoveries andresults assessed. | Diamond core recovery was logged and recorded in the database for Regismanaged drilling, with no significant core loss issues occurring in the mineralisedzones. Average core recovery is 99% for the mineralised zones. Core recoveryfor the historical drilling is not known. |
| RC recovery was visually assessed, with recovery being excellent except in somewet intervals which are recorded on logs. <1% of the overall mineralised zoneshave been recorded as wet. | ||
| Measures taken to maximise sample recovery and ensure representativenature of the samples. | Diamond core was reconstructed for orientationand marking on V-channelorientation racks, and depths are checked and measured against those marked bythe drilling contractors on core blocks. | |
| RC samples were visually checked for recovery, moisture and contamination. Thedrilling contractor utilised acyclone and splitter to provide uniform sample size,and these were cleaned routinely (cleaned at the end of each rod and morefrequently in wet conditions). A booster was also used in conjunction with the RCdrill rig to ensure dry samples are achieved. | ||
| Whether a relationship exists between sample recovery and grade andwhether sample bias may have occurred due to preferential loss/gain offine/coarse material. | Sample recoveries for diamond and RC holes are high, especially within themineralised zones. No significant bias is expectedalthough no recovery and gradecorrelation study was completed. | |
| Logging | Whether core and chip samples have been geologically and geotechnicallylogged to a level of detail to support appropriate Mineral Resourceestimation, mining studies and metallurgical studies. | Lithology, alteration, veining, mineralisation, recovery, RQD, density andgeotechnical/structure were all logged for the diamond core and saved in thedatabase. Core photographs were taken on whole core, and all half core isretained in a core yard for future reference. |
| Lithology, alteration, veining, mineralisation and magnetic susceptibility werelogged from the RC chips and saved in the database. Chips from every intervalare also placed in chip trays and stored in a designated building at site for futurereference. | ||

| For all sample types, the nature, quality and appropriateness of the samplepreparation technique. | Samples are dried, crushed to 10mm, and then pulverised to 85% passing 75µm(80% passing 75µm for the historical drilling). This is considered acceptable foran Archaean gold deposit. | |
| Quality control procedures adopted for all sub-sampling stages tomaximise representivity of samples. | For the Regis managed drilling field duplicates were inserted every 20th sample toassess the repeatability and variability of the gold mineralisation. Laboratoryduplicates were also completed roughly every 15th sample to assess therepeatability and variability ofthe gold mineralisation. | |
| Historical drill hole sampling had field duplicates inserted every 20th sample for allsamples that returned >1g/t Au to assess the repeatability and variability of thegold mineralisation.

Some mineralised coresamples were also sent to other laboratories for umpire assaying. Results of allthe historical QAQC sampling were considered acceptable for an Archaean golddeposit. | ||
| Measures taken to ensure that the sampling is representative of the in situmaterial collected, including for instance results for field duplicate/secondhalf sampling. | Field RC duplicates were taken at the rig from a second chute on the cone splitterallowing for the duplicate and main sample to be the same sizeand samplingmethodand diamond core field duplicates were taken by cutting the half coresample into two quarters.Field duplicates are taken every 20th sample.Laboratory duplicates (sample preparation split) were also completed roughlyevery 15th sample. Two diamond holes were drilled to twin RC holes andsupported the location of the mineralised zone, with the average gold grade beinghigher for diamond in one case, and higher for RC in the other, furtherdemonstrating the nugget effect consistent with Archaean gold mineralisation. | |
| Whether sample sizes are appropriate to the grain size of the materialbeing sampled. | Sample sizes (1.5kg to 3kg) at Rosemont are considered to be a sufficient sizetoaccurately represent the gold mineralisation based on the mineralisation style(hypogene associated with shearing and supergene enrichment), the width andcontinuity of the intersections, the sampling methodology, the coarse goldvariability and the assay ranges for the gold. | |

| Quality of assaydata andlaboratory tests | The nature, quality and appropriateness of the assaying and laboratoryprocedures used and whether the technique is considered partial or total. | All gold assaying was completed by commerciallaboratories (Kalassay, SGS,Aurum and MinAnalytical) using either a 40g or 50g charge for fire assay analysiswith AAS finish. This technique is industry standard for gold and consideredappropriate. |
| For geophysical tools, spectrometers, handheld XRF instruments, etc, theparameters used in determining the analysis including instrument makeand model, reading times, calibrations factors applied and their derivation,etc. | A handheld magnetic susceptibility meter (KT-10) was used to measure magneticsusceptibility for some RC samples, and is recorded in the logging spread sheets.The results were not used in the delineation of mineralised zones or lithologies. | |
| Nature of quality control procedures adopted (e.g. standards, blanks,duplicates, external laboratory checks) and whether acceptable levels ofaccuracy (ie lack of bias) and precision have been established. | Certified Reference Material (CRM or standards) and blanks were inserted every25th sample to assess the assaying accuracy of the external laboratories. Fieldduplicates were inserted every 20th sample to assess the repeatability from thefield and variability of the gold mineralisation. Laboratory duplicates were alsocompleted approximately every 15th sample to assess the precision of assaying. | |
| Evaluation of both the Regis submitted standards, and the internal laboratoryquality control data, indicates assaying to be accurate and without significant driftfor significant time periods. Excluding obvious errors, the vast majority of the CRMassaying report shows an overall mean bias of less than 5% with no consistentpositive or negative bias noted.Duplicate assaying shows high levels ofcorrelation and no apparent bias between the duplicate pairs. Field duplicatesamples show marginally acceptable levels of correlation and no relative bias. | ||

| Verification ofsampling andassaying | The verification of significant intersections by either independent oralternative company personnel. | No independent personnel have visually inspected the significant intersections incore or RC chips. Numerous highly qualified and experienced company personnelfrom exploration and production positions have visually inspected the significantintersections in core and RC chips. |
| The use of twinned holes. | Two diamond holes were drilled to twin RC holes and supported the location(width) of the mineralised zone, with the average gold grade being higher fordiamond in one case, and higher for RC in the other, further demonstrating thenugget effect consistent with Archaean gold mineralisation. |

| The factors affecting continuity both of grade and geology. | A brittle sub-vertical quartz dolerite localises and controls the gold mineralisationin the more hypogene-controlled transitional and fresh horizons. In the oxidehorizon, the gold mineralisation is also influenced by the redox fronts, where it issometimes spread in a more flat-lying manner. There is also a direct correlationbetween gold and veining, particularly with laminated and cloudy quartz carbonateveins. | |
| A major regional flexure in the Baneygo Shear offsets the mineralisation andseparates it into a main and north zone. | ||
| Dimensions | The extent and variability of the Mineral Resource expressed as length(along strike or otherwise), plan width, and depth below surface to theupper and lower limits of the Mineral Resource. | The approximate dimensions of the deposit are 4,900m along strike (N-S), 60macross (E-W), and 500m below surface. |
| Estimation andmodelingtechniques | The nature and appropriateness of the estimation technique(s) applied andkey assumptions, including treatment of extreme grade values, domaining,interpolation parameters and maximum distance of extrapolation from datapoints. If a computer assisted estimation method was chosen include adescription of computer software and parameters used. | MPR used the method of Multiple Indicator Kriging (MIK) with block supportadjustment to estimate gold resources into blocks with dimensions of 15m (east)by 20m (north) by 5m (elevation). MIK of gold grades usedindicator variographybased on the two metre resource composite sample grades. Gold grade continuitywas characterised by indicator variograms at 14 indicator thresholds spanning theglobal range of grades. A block support adjustment was used to estimate therecoverable gold Resources at Rosemont. The shape of the local block gold gradedistribution has been assumed lognormal and an additional adjustment for the"Information Effect" has been applied to arrive at the final Resource estimates. |
| MIK was used as the preferred method for estimation of gold Resources atRosemont as the approach has been demonstrated to work well in a large numberof deposits of diverse geological styles. The gold mineralisation seen at Rosemontis typical of that seen in most structurally controlled gold deposits and where theMIK method has been found to be of most benefit. |

| In the MPR study data viewing, compositing and wire-framing have beenperformed using Micromine software. Exploratory data analysis, variogramcalculation andmodelling, and Resource estimation have been performed usingFSSI Consultant (Australia) Pty Ltd (FSSI) GS3M software. GS3M is designedspecifically for estimation of recoverable Resources using MIK. The grade controlmodelling undertaken in the current study is grade control 'as mined', which isdetermined via end of month topographic surfaces (including the ROM) and millproduction figures. | ||
| The sample data set containing all available assaying were composited to twometre intervals each located by their mid-point co-ordinates and assigned a lengthweighted average gold grade. The composite length of two metres was chosenbecause it is a multiple of the most common sampling interval (1.0 metre) and isalso an appropriate choice for the kriging of gold intothe model blocks assumingopen pit mining will occur on approximately 2.5 metre benches. | ||
| The availability of check estimates, previous estimates and/or mineproduction records and whether the Mineral Resource estimate takesappropriate account of such data. | An internal check Ordinary Kriged (OK) estimate was completed which reconcilesclosely with the MPR MIK for both material mined and remaining. | |
| Regis provided grade control drilling data and reconciliation data as part of theMineral Resource estimate update. Grade control drilling is not utilised in theestimation although it is used for validation purposes. | ||
| The assumptions made regarding recovery of by-products. | No by-products are present or modelled. | |
| Estimation of deleterious elements or other non-grade variables ofeconomic significance (e.g. sulphur for acid mine drainagecharacterisation). | No deleterious elements were estimated or assumed. | |
| In the case of block model interpolation, the block size in relation to theaverage sample spacing and the search employed. | Block dimensions are 15m (east) by 20m (north) by 5m (elevation) and was chosenas it approximates the average drill hole spacing in the horizontal direction, withthe 5m elevation being a multiple of the mining bench height of 2.5m. Theinterpolation utilised a 3 pass octant search strategy with category 1 searching15m in the x, 20m in the y direction and 15m in the z direction, 16 minimumcomposites used, a maximum of 4 composites per octant and a minimum of 4octants with data. Category 2 uses a 50% search distance increase but otherwisethe same parameters and category 3 uses the same search distance as category2 but only requires 8 minimum composites and only 2 octants require data. Thesearch on each category is orientated 15 degrees around z (345 degrees in localgrid) and 50 degrees around y (-50 degrees) to align the search ellipse to theorientation and dip of the mineralisation. |

| Description of how the geological interpretation was used to control theresource estimates. | The 2m composites were coded by the 0.1g/t primary domain wireframes, but thenthe weathering profiles were used to split the primary domains into sub-domainsfor the univariate statistics study and indicator statistics study. | |
| Discussion of basis for using or not using grade cutting or capping. | Mine to mill reconciliations suggest that grade truncation is not required prior togenerating conditional statistics as was completed in the previous model. Selectionof the median instead of mean for the highest indicator threshold wasused toguard against a few higher grades within the population from having adisproportional influence on the gold estimation. | |
| The process of validation, the checking process used, the comparison ofmodel data to drill hole data, and use of reconciliation data if available. | The grade estimate was checked against the input resource developmentdrilling/composite data both visually on section (cross and long section) and inplan. The 'as mined' grade control study described above was another form ofvalidation used, where the agreement between the predicted MIK Resource and'as mined' GC model is good. The tonnes and grade predicted by both models at0.4 g/t Au cut-off are comparable with less than 10% difference in ounces for alltimeframes. | |

| Cut-offparameters | The basis of the adopted cut-off grade(s) or quality parameters applied. | The cut-off grade of 0.4g/t for the stated Mineral Resource estimate is determinedfrom economic parameters and reflects the current and anticipated miningpractices. |
| Mining factorsor assumptions | Assumptions made regarding possible mining methods, minimum miningdimensions and internal (or, if applicable, external) mining dilution. It isalways necessary as part of the process of determining reasonableprospects for eventual economic extraction to consider potential miningmethods, but the assumptions made regarding mining methods andparameters when estimating Mineral Resources may not always berigorous. Where this is the case, this should be reported with anexplanation of the basis of the mining assumptions made. | The Resource model assumes open cut mining is completed and a moderate tohigh level of mining selectivity is achieved in mining. It has been assumed thathigh quality grade control will be applied to ore/waste delineation processes usingAC/RC drilling, or similar, at a nominal spacing of 8m (north –along strike), 5m(east –across strike), by 1.5m downhole, and applying a pattern sufficient toensure adequate coverage of the mineralisation zones.This is similar to the current mining practises at Rosemont, which applies a patternof 10m (north –along strike), 5m (east –across strike), by 1m downhole. |
