SIGNIFICANT EXPLORATION DRILLING RESULTS AT DUKETON
HIGHLIGHTS
Further High Grade Gold Intercepts at Baneygo
-
Further excellent gold results were received from a 190 hole RC programme completed during the September 2015 quarter at Baneygo, 12km south of Rosemont. Significant gold results greater than 50 gram-metres include:
-
10m @ 6.36g/t Au from 95m in hole RRLBYRC142
-
o19m @ 4.31g/t Au from 76m RRLBYRC162o18m @ 3.36g/t Au from 12m RRLBYRC166o13m @ 10.8g/t Au from 29m RRLBYRC178o14m @ 5.46g/t Au from 22m RRLBYRC201o8m @ 10.7g/t Au from 13m RRLBYRC220o4m @ 24.0g/t Au from 39m RRLBYRC229o10m @ 6.11/t Au from 147m RRLBYRC243o11m @ 16.7g/t Au from 208m RRLBYRC278o18m @ 4.73/t Au from 69m RRLBYRC315o7m @ 12.01g/t Au from 94m RRLBYRC319oRRLBYRC322 -
18m @ 4.73/t Au from 69m
-
o7m @ 12.01g/t Au from 94mo25m @ 3.27g/t Au from 82m -
These results over a three kilometre strike are from 40m spaced infill traverses and continue to confirm a much larger mineralised system than previously identified in limited drilling in four discrete areas (small historical Resource of 43Koz in these areas).
-
A new Resource is expected to be estimated by the end of the December 2015 quarter.
First Pass Drilling at Idaho Confirms Prospectivity of Rosemont-Baneygo Trend
-
First pass reconnaissance RC drilling at Idaho prospect (2.2km north of Baneygo) returned significant results:
-
5m @ 3.22g/t Au from 24m in hole RRLIHRC002
-
o6m @ 3.16g/t Au from 46m RRLIHRC004o6m @ 5.16g/t Au from 44m RRLIHRC008o5m @ 2.97g/t Au from 49m RRLIHRC011 -
This drilling has confirmed the significant further exploration potential on the 12km Rosemont-Baneygo shear.

Further High Grade Results at Tooheys Well Gold Deposit
-
Further RC drilling at Tooheys Well (2.5km south of Garden Well) has confirmed a new structure with high grade gold mineralisation. Significant new drilling results greater than 20 gram-metres at Tooheys Well include:
-
54m @ 3.55g/t Au from 55m in hole RRLTWRC036
-
o39m @ 3.86g/t Au from 53m RRLTWRC044o44m @ 1.18g/t Au from 52m RRLTWRC028o15m @ 2.95g/t Au from 54m RRLTWRC043o20m @ 2.98g/t Au from 78m RRLTWRC032o35m @ 1.11g/t Au from 71m RRLTWRC033o27m @ 1.65g/t Au from 58m RRLTWRC040o24m @ 1.78g/t Au from 124m RRLTWRC035 -
The structure is open down dip and along strike to the south for 750 metres. Further RC drilling is planned along strike in the December 2015 quarter to continue to define the extent of gold mineralisation along strike and down dip.
High Grade Gold Intercepts at Coopers Gold Deposit
-
Significant gold results were returned from a 40 hole AC and 9 hole RC drilling programme completed at Coopers, 11km south of Moolart Well. Results greater than 20 gram-metres from significant RC and AC holes include:
-
9m @ 2.31g/t Au from 70m in hole RRLCPRC013
-
8m @ 3.68g/t Au from 77m RRLCPRC014
-
o11m @ 2.05g/t Au from 50m RRLCPAC076o5m @ 14.1g/t Au from 53m RRLCPAC077o4m @ 5.73g/t Au from 56m RRLCPAC082 -
A programme of RC and Aircore drilling is planned to fully define gold mineralisation along strike to the north and south and a gold Resource estimate will be completed in the December quarter.
Drilling of Rosemont South Underground Panel
-
Results from a 6 hole diamond drilling programme to test the geological model on an area immediately to the south of the Rosemont Main pit, approximately 250 metres below surface returned significant results including:
-
15.0m @ 2.11g/t Au from 341m in hole RRLRMRCD006
-
o0.74m @ 11.5g/t Au from 156.74m RRLRMRCD004o22.5m @ 1.61g/t Au from 384.2m RRLRMRCD003o66.6m @ 1.39g/t Au from 246m RRLRMRCD005o0.85m @ 4.48g/t Au from 380.15m RRLRMRCD003 -
Results are encouraging as they show strong continuation of the mineralised structure but are not as high grade as some of the surrounding earlier intercepts. On interpretation of results it is now thought the high grade zone is plunging moderately north as opposed to the south plunging interpretation on which these holes were planned.
-
Further diamond drilling is planned to test the northerly plunge in this area and another programme is being designed to test another high grade shoot (also north plunging) under the central part of the Rosemont Main pit.
Drilling Commences at Gloster
- A 20,000m infill and extensional RC drill programme has commenced at the recently acquired Gloster Gold Deposit (26km west of Moolart Well) to facilitate an updated Resource estimate planned for the December 2015 quarter.

ANNOUNCEMENT
Baneygo Gold Project
Background
The current Baneygo gold Resource is located 12 kilometres south of the Rosemont gold mine and is hosted in a quartz dolerite unit believed to be the same unit hosting gold at Rosemont. The current JORC 2004 gold Resource at Baneygo of 43,000oz occurs in 4 small deposits namely Baneygo (8,000oz), Baneygo Beacon (14,000oz), Baneygo South (15,000oz) and Sydney Mint (6,000oz) over a strike distance of 3km. Regis has been drilling the four small deposits and along strike over the past two quarters.

Historical drilling at Baneygo is generally only to 50 metres and in some places to 100m vertical depth. Very little drilling has been completed between the four small deposits with up to 250m between drill traverses.
Recent Drilling
Further RC drilling (190 holes RRLBYRC141-330 for 18,465m) was completed in the September 2015 quarter to further define the strike extent of mineralisation and to expand the historical Resource by drilling to approximately 100m depth and testing for gold mineralisation between the four small deposits. Initial RC drilling in the June 2015 quarter focused on testing the quartz dolerite host on 20m spaced holes on 80m spaced east west traverses. The recent September 2015 quarter drilling has reduced the drill spacing to 20m spaced holes on 40m spaced east west traverses in areas where significant gold mineralisation was encountered.
Highly encouraging gold results were received from holes in the 40m spaced east west drilling traverses. Significant gold results greater than 8gm are shown below.

Geology & Cross Sections
Two cross sections with updated RC drill results showing the nature of gold mineralisation in the quartz dolerite unit are shown below.
==> picture [405 x 287] intentionally omitted <==
Baneygo drilling on oblique cross sections 6906700mN and 6907450mN. Holes drilled towards 254°.
The geology is similar to Rosemont with gold hosted in a steeply east dipping 345° trending quartz-dolerite unit intruding an ultramafic sequence. Gold mineralisation is associated with quartz-carbonate-chlorite-sulphide alteration and is restricted to the quartz dolerite unit which is generally approximately 80m wide. Weathering depths vary from 20m to 50m vertical depth.

Work Programme
No significant drilling programmes are planned in the December 2015 quarter as geotechnical, metallurgical and bulk density test work is completed on diamond drill core with a view to completing an updated Resource estimate by the end of December 2015 quarter. A Mining Lease application has been lodged over the Baneygo Gold Deposit and is expected to be granted in the first half of calendar 2016.
Regional Opportunity Rosemont – Baneygo Trend
The gold mineralisation at Baneygo is still open to the south for 4km and to the north for 12km to Rosemont. The same prospective quartz-dolerite unit continues to the south and the north and drilling along this unit is sporadic. First pass reconnaissance RC drilling of this prospective unit continued to the north of Baneygo during the quarter and significant gold mineralisation was intersected at a new prospect called Idaho.
Idaho Gold Prospect
Background
The Idaho Gold Prospect is located 2.2km to the north along strike of the existing Baneygo Beacon pit. A first pass RC drill programme was completed to test the economic potential of gold mineralisation within the quartz-dolerite. This unit is the strike continuation of the gold mineralised quartz-dolerite at Baneygo. Results have highlighted the potential for further drilling along strike.
Recent Drilling
Reconnaissance RC drilling commenced north of Baneygo at Idaho early in the September 2015 quarter. A total of 15 holes were drilled (RRLIHRC001-015) for 1,350m. Gold results were encouraging and hence a further 25 RC holes (RRLIHRC016-040) were drilled for 2,001m to reduce the drill spacing to 40m traverses near Idaho and 80m traverses further north.
Assay results for holes RRLIHRC016-040 are pending. Significant gold results for holes RRLIHRC001-015 greater than 8gm are shown below:

Geology & Cross Section
The geology at Idaho is similar to Baneygo and Rosemont with gold hosted in a steeply east dipping 345° trending quartz-dolerite unit intruding in an ultramafic sequence. Gold mineralisation is associated with quartz-carbonate-chlorite-sulphide alteration and is restricted to the quartz-dolerite unit which is generally approximately 80m wide. The weathering depth at Idaho is approximately 50m vertical depth.

Work Programme
Further drilling will be planned once all gold assay results have been returned. The current expectation is that RC drilling will be extended on 80m spaced lines to test the mineralised trend continuation further to the north of Idaho.
Tooheys Well Gold Prospect
Background
The Tooheys Well gold prospect is located on a granted Mining Lease, 2.5km south of the Garden Well gold mine. Gold mineralisation was previously defined in two North South trending shear zones 100m apart hosted in chert and fine grained sediments.

==> picture [67 x 21] intentionally omitted <==
Recent Drilling
A further programme of 21 RC holes (RRLTWRC025-045) was drilled for 2,294m in the September 2015 quarter to follow-up anomalous gold mineralisation in the eastern shear zone defined last quarter. Gold analytical results were received for holes RRLTWRC025-045. The recent drilling has confirmed new significant gold mineralisation in the Eastern shear zone which is mineralised over a strike length of 280m from 6909220mN to 6909500mN.
==> picture [360 x 461] intentionally omitted <==

The eastern shear zone was initially intersected by holes RRLTWRC014, 015 and 018 and followed up with holes RRLTWRC025-028 and 035 on section 6909260mN and appears to have a moderately steep dip of 60° to the east. Host rocks are chert and shale and weathering extends to 80 to 100m vertical depth. The Eastern shear zone is untested for 750m to the south and is open down dip. The Western shear zone was not drilled in the September 2015 quarter and is also untested to the south and north.

Work Programme
Further RC drilling will continue in the December 2015 quarter to determine the continuity of gold mineralisation in the eastern shear zone 750m to the south of 6909220mN, initially on 80m spaced East-West sections in the oxide zone and to target gold mineralisation in the fresh rock zone. Further RC drilling is also planned to test the Western shear zone.
Coopers Gold Prospect
Background
The Coopers gold prospect is located on a granted Mining Lease 11km south of Moolart Well and 600m north of Dogbolter, and is located on the same shear zone hosting those two deposits. An earlier programme of Aircore drilling and a limited 10 hole RC programme by Regis on 40m and 80m spaced E-W traverses defined gold mineralisation in the oxide zone over a strike distance of 400m. The gold mineralised zone is weakly mineralised to the north and still requires further drilling.
A small programme of RC drilling and a more extensive programme of Aircore drilling was completed in the September 2015 quarter to test the strike continuation of gold mineralisation at Coopers.
Recent Drilling
Regis drilled 9 RC holes (RRLCPRC011-019) and 40 Aircore holes (RRLCPAC071-110) at Coopers during the September 2015 quarter. Analytical results were received for all the holes.

These results will provide enough data to complete a preliminary Resource estimation and review of the Coopers Prospect in the December 2015 quarter. Further drilling is planned to fully define the northern and southern extent of gold mineralisation.
Geology & Cross Section

Coopers geology and drilling showing the main gold mineralised zone and significant September Quarter results.
Gold mineralisation at Coopers is located in a moderately east dipping shear zone hosted in dolerite and diorite intrusive units near a basalt contact that also dip at 45° to the east. A 5m to 10m transported cover sequence conceals the gold mineralisation and weathering of the basalt and dolerite units extends to 90m depth. Most drilling to date has defined the gold mineralisation in the oxide zone and only two RC holes have tested the fresh rock zone.

Rosemont Underground Potential
Geological Modelling of Rosemont Underground Zones
In the June 2015 quarter a gold mineralised envelope with drilling intercepts greater than 0.5g/t gold was modelled for the mineralised quartz dolerite unit along the extent of the Rosemont deposit. During this process several high grade steeply south plunging shoots were defined. The first area modelled was at the south end of Rosemont and this is shown in the boxed area of the isometric long section below.

Recent Drilling
As a preliminary step towards advancing more detailed underground studies at Rosemont, a first pass, six hole diamond drilling programme RRLRMRCD001-006 was completed in the southern area for 2,043m to test the geological model as well as geotechnical and hydrogeological conditions.

Interpretation of results
Gold analytical results from the six hole diamond drilling programme are encouraging as they show continuity of the gold mineralised structure. The gold grades are not as high as some of the surrounding intercepts, however it is now thought that the high grade shoot is plunging moderately north and not south as was earlier interpreted. This is shown in the long section below where other Rosemont high grade shoots are plunging north.

Rosemont contoured drill hole gold gram-metre assays Long Section showing final Main pit design and location of the 6 hole RRLRMRCD001-006 diamond drilling programme at the Southern high grade gold shoot.
Early indications from this 6 hole diamond drilling programme are that geotechnical and hydrological conditions in the area drilled would be amenable to underground mining.
Work Programme
Further assessment of the Southern and Central high grade shoot under Main pit is planned in the December quarter. This will allow the design of a diamond drilling programme to test the northerly plunge interpretation of the high grade Southern and Central shoots. Other high grade shoots will also be assessed. Further drilling will be prioritised between these targets.
RC Drilling Commences at Gloster Gold Deposit
Background
The Gloster gold deposit located 26km west of Moolart Well was acquired by Regis in the June 2015 quarter. Gloster was historically mined from 1902-1908 and was extensively drilled from 1984-1996. A Resource estimate was completed in 1997 (in compliance with the 1996 JORC Code and Guidelines) for 8.28MT at a grade of 1.37g/t Au for 365,000oz.
Work Programme
Regis has commenced RC drilling at Gloster to infill the existing gold Resource and to test for extensions of gold mineralisation below the current historical level of drilling in the fresh rock zone. A total of 177 RC holes are planned for 20,000m of drilling in the December 2015 quarter. The drilling will enable an update of the Resource estimate and will form the basis of mining feasibility studies.
A Mining Lease application has been lodged over the Gloster gold deposit and is expected to be granted in the December 2015 quarter.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation Commentary |
|---|---|
| Sampling techniques |
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. Baneygo: The Baneygo gold deposit was sampled using Reverse Circulation (RC) Drill Holes on a nominal 20m east by 40m north initial grid spacing. The current study used the sampling from 140 holes for 12,634 m, which were drilled angled -60 degrees to 254 degrees. Coopers: The Coopers gold prospect was sampled using Reverse Circulation (RC) drill holes on a nominal 20m east by 40m north initial grid spacing. The current study used the sampling from 10 holes for 998 m which were drilled angled -60 degrees to 270 degrees. Tooheys Well: The Tooheys Well gold prospect was sampled using Reverse Circulation (RC), drill holes on a nominal 40m east spaced holes on 80m north initial grid spacing. The current study used the sampling from 19 holes for 2,377 m, which were drilled angled -60 degrees to 270 degrees. Rosemont: 6 RC-precollar and diamond tails (DD - NQ3 or HQ3) were drilled to verify the continuity of high grade mineralisation at depth and to gain geotechnical information relevant for underground mining and infrastructure. The current study used the sampling from 6 holes for 2,043 m which were drilled angled -60 degrees to 270 degrees. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

| Regis drill hole sampling had certified standards and blanks inserted every 25th sample to assess the accuracy and methodology of the external laboratories, and field duplicates (RC only) were inserted every 20th sample to assess the repeatability and variability of the gold mineralisation. Laboratory duplicates were also completed approximately every 15th sample to assess the precision of the laboratory as well as the repeatability and variability of the gold mineralisation. Results of the QAQC sampling were considered acceptable for an Archaean gold deposit. |

| Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. Baneygo, Coopers and Tooheys Well: For the Regis RC drilling 1m samples were obtained by cone splitter (2.5kg – 3.0kg) and were utilised for lithology logging and assaying. The drilling samples were dried, crushed and pulverised to get 85% passing 75µm and were all Fire Assayed using a 50g charge (Bureau Veritas, Min Analytical and Aurum). Rosemont: Diamond drilling completed to industry standard using varying sample lengths (0.3 to 1.2m) based on geological intervals, which are then dried, crushed and pulverised to get 85% passing 75µm and were all Fire Assayed using a 50g charge (Bureau Veritas, Min Analytical and Aurum). |
|
| Drilling techniques |
Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). Baneygo, Coopers and Tooheys Well: RC drilling completed with a 139mm diameter face sampling hammer accounts for 100% of the drilling meters in the project area with an average hole depth of 90.2m for Baneygo, 99.8m for Coopers and 125.1m for Tooheys Well. Rosemont: Surface diamond drilling carried out by using both NQ3 or HQ32 (triple tube) and NQ2 or HQ2 (standard tube) techniques. Core is routinelyorientated byREFLEX ACT III tool. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. Baneygo, Coopers and Tooheys Well: RC recovery was visually assessed, with recovery being excellent except in some wet intervals which are recorded on logs. <1% of the overall mineralised zones have been recorded as wet. Rosemont: DD core was measured and compared to the drilled intervals, and recorded as a percentage recovery. |

|---|---|
| Measures taken to maximise sample recovery and ensure representative nature of the samples. Baneygo, Coopers and Tooheys Well: RC samples were visually checked for recovery, moisture and contamination. The drilling contractor 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 RC drill rig to ensure dry samples are achieved. Rosemont: The target zones were highly competent fresh rock, so the DD method provides high recovery. |
|
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. Baneygo, Coopers and Tooheys Well: Sample recoveries for RC drilling are high, especially within the mineralised zones. No significant bias is expected although no recovery and grade correlation study was completed. Rosemont: The DD drill sample recovery is very high, and no significant bias is expected. |
|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Baneygo, Coopers and Tooheys Well: Lithology, alteration, veining, mineralisation and on some holes magnetic susceptibility were logged from the RC chips and saved in the database. Chips from every interval are also placed in chip trays and stored in a designated building at site for future reference. Rosemont: Lithology, alteration, veining, mineralisation and geotechnical information were logged from the DD core and saved in the database. Half core from every interval are also retained in the core trays and stored in a designated building at site for future reference. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. All logging is qualitative except for magnetic susceptibility. |

| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. Baneygo, Coopers and Tooheys Well: All gold assaying was completed by commercial laboratories (Bureau Veritas, Min Analytical and Aurum) using either a 40g or 50g charge for fire assay analysis with AAS finish. This technique is industry standard for gold and considered appropriate. Rosemont: All gold assaying was completed by commercial laboratories (Bureau Veritas, Min Analytical, Aurum and SGS) using either a 40g or 50g charge for fire assay analysis with AAS finish. This technique is industry standard for gold and considered appropriate. |
| For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Baneygo, Coopers, Tooheys Well and Rosemont: No geophysical measurements were routinely made. |
|
| Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. Baneygo, Coopers, Tooheys Well and Rosemont: Certified Reference Material (CRM or standards) and blanks were inserted every 25th sample to assess the assaying accuracy of the external laboratories. Field duplicates (RC only) were inserted every 20th sample to assess the repeatability from the field and variability of the gold mineralisation. Laboratory duplicates were also completed approximately every 15th sample to assess the precision of assaying. Evaluation of both the Regis submitted standards, and the internal laboratory quality control data, indicates assaying to be accurate and without significant drift for significant time periods. Excluding obvious errors, the vast majority of the CRM assaying report shows an overall mean bias of less than 5% with no consistent positive or negative bias noted. Duplicate assaying show high levels of correlation and no apparent bias between the duplicate pairs. Field duplicate samples show marginally acceptable levels of correlation and no relative bias. Results of the QAQC sampling were considered acceptable for an Archaean gold deposit. Substantial focus has been given to ensuring sampling procedures met industry best practise to ensure acceptable levels of accuracy and precision were achieved in a coarse gold environment. |

| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Baneygo, Coopers, Tooheys Well and Rosemont: All geological and field data is entered into excel spreadsheets with lookup tables and fixed formatting (and protected from modification) thus only allowing data to be entered using the Regis geological code system and sample protocol. Data is then emailed to the Regis database administrator for validation and importation into a SQL database using Datashed. |
|
| Discuss any adjustment to assay data. Baneygo, Coopers, Tooheys Well and Rosemont: Any samples not assayed (i.e. destroyed in processing, listed not received) have had the assay value converted to a -9 in the database. Any samples assayed below detection limit (0.01 ppm Au) have been converted to 0.005 ppm (half detection limit) in the database. |
|
| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Baneygo, Coopers, Tooheys Well and Rosemont: Regis drill hole collar locations were picked up by site-based authorized surveyors using Trimble RTK GPS, calibrated to a base station (expected accuracy of 20mm). Downhole surveying (magnetic azimuth and dip of the drill hole) was measured by the drilling contractors in conjunction with Regis personnel using Reflex EZ-Shot Downhole Survey Instrument. The surveys were completed every 30m down each drill hole. Magnetic azimuth is converted to AMG azimuth (-2 degrees) in the database. For Baneygo and Rosemont they are then converted to local grid (AMG +15.5 degrees), with local azimuth to be used in any future Resource estimation. |

| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Baneygo: The initial nominal drill hole spacing was 80m (northing) by 40m (easting), with infill drilling in the gold mineralised zones to 20m easting to a depth of approximately 100 metres from surface. Infill drilling in the north zone has reduced the effective spacing between drill lines to 40 metres (northing) by 20 metres (easting) to a depth of approximately 100 metres from surface. Coopers:The initial nominal drill hole spacing was 80m (northing) by 40m (easting). The drilling completed this period reduced the effective spacing to 20 metres (east) by 40 metres (north) to a depth of 100 metres from surface. Tooheys Well: The nominal drill hole spacing is 80m (northing) by 40m (easting), to a depth of 120 metres from surface. Rosemont: The 6 hole program was designed as infill to an existing 80m by 80m pattern. |
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Baneygo, Coopers, Tooheys Well and Rosemont: The data spacing and distribution is sufficient to demonstrate spatial and grade continuity of the mineralised domains to support the definition of Inferred and Indicated Mineral resources under the 2012 JORC code. |

| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. Baneygo:The mineralisation at Baneygo is sub-vertical dipping to the east so drilling is orientated to best suit the mineralisation to be roughly perpendicular to both the strike and dip of the mineralisation. Intercepts are close to true-width in most cases, and are not true width where the mineralisation is at its steepest. Coopers:The Coopers drill holes were drilled at -60º to 270° and the mineralised zone is moderately to steeply east dipping. The intercepts reported are close to true width.

|---|---|---|
| Tooheys Well:Minor amounts of drilling by Ashton and Johnsons Well Mining was | ||
| completed although it was mainly shallow and not extensive enough to properly | ||
| define the mineralisation. | ||
| Rosemont:The Rosemont gold deposit was discovered in the 1980s and was | ||
| partially mined as a shallow oxide open pit by Aurora Gold Limited in the early | ||
| 1990s. Reported production was 222kt at 2.65g/t for 18,600 ounces of gold. The | ||
| ground was then acquired by Johnsons Well Mining who defined a resource at | ||
| Rosemont in the late 1990’s.The resource at Rosemont has been held outright by | ||
| Regis since 2006. Regis has conducted further drilling at Rosemont and defined a | ||
| maiden gold Reserve in November 2011. | ||
| Geology | Deposit type, geological setting and style of mineralisation. | Baneygo:The geology is similar to Rosemont with gold hosted in a steeply east dipping 345° trending quartz-dolerite unit intruding an ultramafic sequence. Gold |
| mineralisation is associated with quartz-carbonate-chlorite-sulphide alteration and | ||
| is restricted to the quartz dolerite unit which is generally approximately 80m wide. | ||
| Weathering depths vary from 20m to 50m vertical depth. | ||
| Coopers:Gold mineralisation at Coopers is located in a moderately east dipping | ||
| shear zone hosted in dolerite and diorite intrusive units near a basalt contact that | ||
| also dip at 45° to the east. A 5m to 10m transported cover sequence conceals the | ||
| gold mineralisation and weathering of the basalt and dolerite units extends to 90m | ||
| depth. Most drilling to date has defined the gold mineralisation in the oxide zone | ||
| and only two RC holes have tested the fresh rock zone. | ||
| Tooheys Well:The geology is similar to Garden Well with gold hosted in a | ||
| moderately east dipping North-South trending chert and fine grained sediment unit. | ||
| Gold mineralisation is associated with shearing at the interface between the chert | ||
| and shales. Weathering depths vary from 20m to 70m vertical depth. | ||
| Rosemont: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 carbonate-pyrite-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. | ||
