Shear Zones and is also a follow up on to two historical IP surveys carried out in the 1980’s and 1990’s which only covered small areas at each end of the Grace and Bemm Shear Zones. This GAIP survey will play a crucial role in the design of the Infill RC Drilling program to increase the confidence levels of the existing resource estimate but also to expand the drill coverage of the mineralised system contained within the Grace and Bemm Shear Zones to increase data points contained within the current exploration area.

Mineral Resource Estimate and Exploration Target
Mineral Resource Estimate
The Grace Project has an Inferred Mineral Resource of Oxide / Transitional Mineralisation of 1,590,000 tonnes @ 1.35 g/t Au for 69,000 ozs. The Mineral Resource estimate is based on historic

drilling carried out by Newmont Australia/Newcrest with no subsequent exploration drilling since 2004.
| Mineral Resource | Type | Tonnes (Mt) | Au (g/t) | Ounces |
|---|---|---|---|---|
| Category | ||||
| Inferred | Oxide - Transitional | 1.59 | 1.35 | 69,000 |
| TOTAL | 1.59 | 1.35 | 69,000 |
Table 1 : Mineral Resource Estimate at Grace
The Mineral Resource estimate was carried out on a portion of the mineralised zone at Grace (1,140m strike length of a total strike length of 4,130m) where drilling is at an adequate spacing, and uses appropriate techniques (RC and diamond core) to support the estimate. The remainder of the mineralisation is delineated by RAB drilling and wide spaced RC and diamond core drilling.
==> picture [453 x 252] intentionally omitted <==
Figure 2 : Drill Plan
The Mineral Resource Estimate was completed using the following parameters:
-
The Mineral Resource extends over a strike length of 1,140m (striking to 110) and is between 50 and 140m across (210 – 030). The Mineral Resource extends up to 140m vertically below surface (160m down dip).
-
The Mineral Resource represents a portion of a mineralised zone defined by drilling to extend for 4,130m along strike and up to 500m vertically below surface (550m down dip). The portion selected to be classed as a Mineral Resource is that where RC and diamond drilling have been completed at an adequate spacing, with the balance representing an Exploration Target.
-
Mineralisation is hosted in a steeply dipping stratabound package adjacent to the Bemm Shear, which is oriented to the WNW, and current interpretations indicate that shallow to moderate NW-dipping lodes occur within this package.
-
524 holes have been drilled at the Grace Project for a total of 47,509m. Of these 110 drill holes were used in the resource estimate for a total of 11,465m of drilling. All drilling

was completed by Newcrest.
-
Drilling utilised in the resource estimate was carried out on sections spaced approximately 50m apart, with drilling elsewhere completed on sections approximately 200m apart. Holes were drilled predominantly to direction 016 or 196 (perpendicular to the strike of the deposit).
-
RC drilling was sampled via face sampling hammer, collected by a rig mounted cyclone on 1m intervals and split using a riffle splitter. Diamond core drilling sampled NQ core by splitting the core in half, with 1m intervals used unless adjusted for geological intervals.
-
Samples were analysed at commercial laboratories (ALS, Amdel, Genalysis) using fire assay, AAS and ICP-OES.
-
Quality control protocols included the use of certified reference materials (CRMs),blanks and duplicates.
-
All drill holes were surveyed in either local grid or AMG. As part of the Mineral Resource estimation the local grid conversions were created from scratch to ensure that collar coordinates have acceptable precision.
-
Geological domains were constructed using, on average, a 0.3g/t gold cut-off grade.
-
11 wireframe solids were constructed based on the geological interpretation. Samples within the wireframe were composited to 1.0m intervals.
-
Block grades were estimated using interpolation of the 1m composite data by the Inverse Distance squared method. An ellipsoidal search of 50m with a minimum of 4 samples and maximum of 28 samples was used.
-
A Surpac block model was used for the estimate with a block size of 10m E by 5m N by 5m RL.
-
Bulk density values used for mineralisation was 2.0. These were sourced from historical reporting and are conservative when compared to values used to estimate Mineral Resources at the adjacent Telfer Deposit.
-
The deposit has been classified as an Inferred Mineral Resource based on data quality, sample spacing, and geological interpretation.
-
Significant factors that should be addressed to increase confidence in the Mineral Resource include additional drilling and twinning/confirmation of historical holes, density measurements, and more detailed QA/QC and geostatistical studies.
These notes should be read in conjunction with the information detailed in Appendix 1.

In addition to the Mineral Resource an Exploration Target of between 2.2 and 2.8 Mt at a grade between 0.9 and 1.3 g/t has been defined. This corresponds to a potential content of between 64,000 and 117,000 ounces of gold, though it should be noted that the tonnage and grade of the Exploration Target is conceptual, that there is insufficient exploration in the area of the Exploration

Target to estimate a Mineral Resource and it is uncertain if future exploration will result in the estimation of a Mineral Resource. The Exploration Target is based on mineralisation intersected in both near surface RAB drilling and deep diamond drilling.
Additional exploration and infill drilling on the full 4,130m strike along the Grace-Bemms shear zone has the potential to expand and increase the confidence level of the known Resource.

| Sampling techniques |
• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. In cases where • ‘industry standard’ work has been done this would be relatively simple (eg • ‘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 (eg submarine nodules) may warrant disclosure of detailed information. |

| Geology | • Deposit type, geological setting and style of mineralisation. |
• The geological setting is the Paterson Province Proterozoic aged meta-sediment hosted hydrothermal shear, fault and strata/contact controlled precious and/or base metal mineralisation which is typically sulphide bearing. The mineralisation in the region is interpreted to be granite related. The Paterson is a low-grade metamorphic terrane but local hydrothermal alteration and/or contact metamorphic mineral assemblages and styles are indicative of a high-temperature local environment. Mineralisation styles include vein, stockwork, breccia and skarns. • The Grace Gold-Copper Project, gold-copper mineralisation is hosted by laminated and banded carbonaceous pyritic dolomitic siltstones and micritic dolomite. Intrusive dolerite units are also known to be associated with mineralisation within the sequence. The host rocks are variably contorted and brecciated with intense albite alteration. High grade gold, chalcopyrite, +/-arsenopyrite, +/- pyrite occur as veins which appear linear features and are spaced up to 50 m apart. Based on recent Leapfrog modelling of past work undertaken by Criterion there appears to be ore shoots associated with secondary structures cutting the veins that have a plunge and have not been adequately tested. • Two principal targets are being targeted.

• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut- off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearlystated. |
• • • • • • |
Reported aggregated intervals have been length weighted. No density or bulk density is available and so no density weighting has been applied when calculating aggregated intervals. No top-cuts have been applied. A nominal 0.50g/t gold lower cut-off grade is applied. Higher grade intervals of mineralisation internal to broader zones of mineralisation are reported as included intervals. Metal equivalence is not used in this report. |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length,true width not |

Grace Deposit: The interpreted stratabound/reef vein breccia (oxide and primary) mineralisation is interpreted to be dominantly shallow to moderate northwest dipping (and west- northwest striking) within a steeply dipping lithological package and all drill holes are typically vertical or less frequently inclined between -50˚ and -60˚toward the southwest and northeast. In general, the intersection angles for the variety of drilling programs appear to be at a moderate angle to the overall mineralised zones. Therefore, the reported downhole intersections are estimated to approximate 60-80% true width. All intersections reported are down hole intervals no suggestion of true widths is implied. |

| Other substantive exploration data |
• Other exploration data,if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• All meaningful and material information has been included in the above text or can sometimes be found in previous WA DMP WAMEX publicly available reports. Data from these reports is still being compiled and verified. • The details of the Grace Project area Induced Polarisation surveys, including IP Chargeability and resistivity anomalies can be found in the WA DMP publicly available WAMEX reports A24465 (1988) and A53751 (1997). • Zones of mineralisation and associated waste material have not been measured for their bulk density. • Multi element assaying was conducted variously for a suite of potentially deleterious elements including arsenic, sulphur, lead, zinc and magnesium. • No Geotechnical logging (eg Recovery, RQD and Fracture Frequency) was obtained from the WAMEX reports. • No information on structure type, dip, dip direction, alpha angle, beta angle, gamma angle, texture and fill material was obtained from the WAMEX reports. • Metallurgical test-work results available for the Grace Project area include metallurgical tests conducted by Oretest Pty Ltd in December 1997 outlined in WAMEX report A53751 (1997). • Bottle roll cyanidation test were conducted on two (2) samples of gold bearing ore from the Lakes prospect that graded 26.1g/t gold (sample 4129) and 8.72g/t gold (sample 4130). Gold recoveries were excellent at 96.1% and 98.5% respectively. Leach kinetics curves for both samples displayed continuing leaching beyondthe24 our period which suggests the presence of coarse/slow leaching gold which is consistent with the spotty head assays. A gravity pre-treatment step was advised for these ores to increase initial cyanide and/or oxygen concentration. |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). |
• At this stage mineralisation identified by diamond, RC, Aircore and RAB drilling within the Grace Project area (ie Grace, Bemms, Grace East, Genoa, Lakes and Halls Knob) have a range of drill defined limits along strike , across strike and down dip and each remain open in all directions and require further work/drilling to test for lateral (in particular west-northwest) |

Section 3 Estimation and Reporting of Mineral Resources
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Database integrity |
• Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. • Data validation ~~rocedures used~~ |
• Following importation, the data goes through a series of digital and visual checks for duplication and non-conformity, followed by manual validation by the competent person • The database has been systematically audited by the CP. • Original drilling records were compared to the equivalent records in the database. No major discrepancies were found. |
| Site visits | ~~p~~ • Comment on any site visits undertaken by the Competent Person and the outcome of those visits. • If no site visits have been undertaken indicate why ~~this is the case~~ |
• No site visits have been undertaken due to the remote location of the project area. All drill collars have been rehabilitated and it is felt there is adequate documentation in the WAMEX reports to support an Inferred Resource. |
| Geological interpretation |
~~.~~ • Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral deposit. • Nature of the data used and of any assumptions made. • The effect, if any, of alternative interpretations on Mineral Resource estimation. • The use of geology in guiding and controlling ~~Mineral Resource~~ |
• The confidence in the geological interpretation is considered to be moderate to high. • A geological model was established by previous explorers. The mineralisation geometry has a very strong relationship with the lithological interpretation and structure and was confirmed by deep holes intersecting extensions to mineralisation. • Additional drilling will improve the definition of the key control on mineralisation (i.e. interpreted flat structures vs the controlling Bemm Shear) and increase the confidence in the geological interpretation. |
| Dimensions | • The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource. |
• The dimensions of the mineralised zone based on drilling are 4130m along strike (110 o) and 50 – 140m across (210 o– 030 o). The fresh mineralisation has been drilled up to 500m vertically below surface (550m down-dip). • The dimensions of the Mineral Resource are 1140m along strike (110 o) and 50 – 140m across (210 o– 030 o). The Mineral Resource extends up to 140m vertically below surface (160m down-dip). |

| Estimation and modelling techniques |
• The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by- products. • Estimationofdeleterious elements or other non- grade variables of economic significance (eg sulphur for acid mine |
• Grade estimation using Inverse Distance Squared (ID2) was undertaken using Surpac software. Detailed statistical and geostatistical investigations have been completed on the captured estimation data set (1m composites). • One element, Au g/t was estimated using parent cell estimation, with density being assigned by lithology and oxidation state. Drill hole data was coded using three dimensional domains reflecting the geological interpretation based on the structural, lithological, alteration and oxidation characteristics of the Mineral Resource. One metre composited data was used to estimate the domains. The domains were treated as hard boundaries and only informed by data from the domain. The impact of outliers in the sample distributions used to inform each domain was reduced by the use of grade capping. Grade capping was applied on a domain scale and a combination of analytical tools such as histograms of grade, Coefficient of Variation (COV) analysis and log probability plots were used to determine the grade caps for each domain. • A top cut of 11.83g/t was used • A Parent block size was selected at 10mE x 5mN x 5mRL for both the deposits, with sub-blocking down to 2.5 x 1.25 x 1.25. • A single ellipsoidal Search Pass was used with a search distance of 150m along strike (to 285), and 75m in the vertical and horizontal directions. A minimum of 4 samples and a maximum of 28 samples were used in the estimation pass with an ellipsoid search. • No previously released JORC compliant Mineral Resource • Estimates have been completed on the Grace Deposit. • No assumption of mining selectivity has been incorporated into the estimate. • Only Au was estimated in the Mineral Resource. • The deposit mineralisation was constrained by wireframes |

• The resource model assumes open cut mining is completed and a high level of mining selectivity is achieved in mining. It has been assumed that high quality grade control will be applied to ore/waste delineation processes using grade control drilling, or similar, at a nominal spacing of 10m (north –along strike) and 5m (east – across strike), and applying a pattern sufficient to ensure adequate coverage of the mineralisation zones. |
| Metallurgical factors or assumptions |
• The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made. |
• No detailed metallurgical data exists; where required area analogues (e.g. Telfer) were used to determine the prospects of eventual economic extraction. • Suitable metallurgical tests will be carried out prior to any classification upgrade in confidence of the Grace Deposit. |

| Environmental factors or assumptions |
• Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of theprocess of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potentialenvironmental impacts, particularly for a greenfields project, may not always be well advanced, the status of early consideration of thesepotential environmental impacts should be reported. |
• No assumptions have been made regarding environmental factors. The Company will work to mitigate environmental impact as a result of any future mining or mineral processing. |
| Bulk density | • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk densityforbulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit. • Discuss assumptions for bulk densityestimates |
• No bulk density measurements exist for the deposit, however Newcrest used an SG of 2.0 for previous modelling of the mineralisation. • This is consistent with the Telfer Deposit, where density measurements used in Mineral Resource estimations range between 2.00 and 6.24 (source: Newcrest Technical Report on Telfer Project Dec 31 2013). • As a consequence an SG of 2.0 has been used in the MRE |

| Classification | • The basis for the classification of the Mineral Resources into varying confidence categories. • Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result |
• The Mineral Resource estimate is reported here in compliance with the 2012 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’ by the Joint Ore Reserves Committee (JORC). The resource was classified as an Inferred Mineral Resource based on data quality, sample spacing, and lode continuity. • Significant factors that should be addressed to increase confidence in the Mineral Resource include additional infill and extensional drilling and twinning/confirmation of historical holes, density measurements, and more detailed QA/QC and geostatistical studies. • The input data is comprehensive in its coverage of the mineralisation and does not favour or misrepresent in-situ mineralisation. The definition of mineralised zones is based on a good geological understanding producing a robust model of mineralised domains. This model has been confirmed by infill and extensional drilling which supported the interpretation. |

• The results of any audits or reviews of Mineral Resource estimates. |
• No audits or review of the Mineral Resource estimate has been conducted. |

• Where appropriate a statement of the relative accuracy and confidence level in the Mineral Resource estimate using an approachorprocedure deemed appropriate by the Competent Person. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed appropriate,a qualitative discussion of the factors that could affect the relative accuracy and confidence of the estimate. • The statement should specify whether it relates to global or local estimates, and, if local state the relevant tonnages which should be relevant to technical and economic evaluation. Documentation should ~~include assumptions made~~ |
• The lode geometry and continuity has been adequately interpreted to reflect the level of Inferred Mineral Resource. • The data quality is good and all drill holes have detailed logs produced by qualified geologists.
