Highlights
-
2,000m Reverse Circulation drilling programme to commence at Lake Grace Gold Project
-
Targeting the historic Challenger Prospect – a stand-out gold target unexplored for 25 years
-
Targeting defined by historic drilling where Norths Ltd found gold mineralisation in 1990’s
-
Sultan to test depth and tenor of known mineralisation
-
First private landowner access agreement at Lake Grace executed
The Board of Sultan Resources Ltd ( Sultan or the Company ) is pleased to inform shareholders that all approvals and relevant access agreements are in place for the Challenger Prospect at Lake Grace, paving the way for drilling to commence at the project in the second half of March 2019.
Drilling Program
The Company is planning to drill 12 Reverse Circulation (“RC”) holes for approximately 2,000m targeting a 1km long, >0.1g/t Au aircore gold anomaly defined by North Limited (“North”) in exploration programs undertaken across the area in the mid-1990s[1] . North also drilled two diamond core holes into the anomaly and intersected broad zones of low-grade gold mineralisation containing bands of higher-grade gold. Sultan’s drill program is designed to confirm the extent and tenor of the surface gold mineralisation, test the depth and down-plunge extent of the higher-grade mineralised zones and provide an understanding of the stratigraphy and structure across the Challenger Prospect.
Managing Director, Steve Groves, commented: “We are very excited to have the opportunity to sink the first drill holes into the Challenger Prospect in over 25 years. This is a stand-out gold target showing a very large body of anomalously-mineralised mafic granulite containing evidence of higher-grade mineralization from historic drilling. With the recent progress at nearby Tampia and Katanning gold deposits, understanding of gold systems in the Southwest Yilgarn has improved markedly and Sultan has a fantastic opportunity to apply that knowledge to the Challenger Prospect. The company has worked hard to gain the trust of the local community and has negotiated the first landowner access agreement to the Challenger Prospect in 25 years.”

Challenger Prospect – Lake Grace
The Lake Grace Project lies in the eastern wheatbelt, approximately 250km east-southeast of Perth. The Project comprises five tenements covering an area of approximately 690km[2] and has been subject to sporadic exploration with the most focussed efforts completed by North during the 1990s[1] . This work uncovered a series of gold anomalies related to mafic granulites over a northwest-trending zone striking for approximately 17km. The most prominent of these zones is the Challenger Prospect, where aircore drilling defined a 1km long, greater-than 0.1g/t Au near-surface gold anomaly (significant intersection included in Table 1 and Figures 2 & 3, below).
North followed up the aircore program with two deeper, angled diamond holes beneath the centre of the aircore anomaly. Both holes intersected broad thicknesses of gold anomalous mafic granulites containing distinct higher-grade zones within the package. Significant intersections from the drilling are included in Table 1 and Figure 3, below.

The mineralisation is hosted in sulphidic bands within the mafic granulites and is interpreted to be broadly similar in nature to that occurring at the nearby 695koz Tampia Gold Deposit[2,4] (resource details in Appendix 1) and 1Moz Katanning Gold Deposit[3] (resource details in Appendix 1). Both Explaurum[2] and Ausgold[3] have noted that high-grade gold is occurs in lodes or shoots and develops coincident with dilatant zones associated with strong deformation. The Challenger prospect is associated with a circular magnetic feature that possibly represents deformed stratigraphy and the drill program is designed to test the structure of the mafic granulite down dip and along strike beneath the entire length of the surface gold anomaly.

Challenger Prospect - Exploration Potential
Based on the historic exploration results by North, Sultan believes that potential exists for a sizeable accumulation of gold at Challenger. Aircore and limited diamond drilling have defined a gold-mineralised sequence of mafic granulite rocks that appear similar in nature to those that host large moderate grade gold deposits nearby at Tampia[2,4] (12.1Mt @ 1.8g/t for 695koz – Appendix 1) and Katanning[3 ] (25.1Mt @ 1.29g/t for 1.04Mt – Appendix 1).
At surface, the >0.1 g/t Au anomalous mafic granulite extends for approximately 1km and is up to 150m wide. At depth, diamond drilling has shown the anomalous granulites to be up to and over 100m thick and to extend along a shallow dip for at least 200m. The granulite package is consistently anomalous in gold content and is open in all directions.
Elevated gold grades occur within the gold-anomalous package in narrower, often sulphidic bands and that can contain grades across several metres well in excess of 1g/t Au[1] . Individual assay results across 1m intervals have returned values as high as 34 g/t Au[1] (repeat assay). The mafic granulites are open at depth and along strike though gold potential beyond the extent of the existing drilling is unknown. High-grade gold occurs in shoots at both Katanning[3] and Tampia[2] coincident with well-developed cleavage where goldmineralised granulites are strongly deformed or folded. The geometry of the Challenger granulites is unknown at this stage and understanding this is one of the objectives of the current drill program.
Sultan believes, given the evident volume of gold anomalous mafic granulites and presence of higher-grade zones within the package, that high potential exists for the discovery of a significant gold deposit at the prospect. The current drill program has been designed to collect geology and assay data from across the

known extent of gold anomalism and, if results warrant, will allow the Company to model the mineralisation and calculate an Exploration Target range to guide future exploration programs.
Land Access
The entire Lake Grace Project area is situated in the wheatbelt district of southern Western Australia, with most of the licences located on privately-owned farmland. Individual Landowner Access agreements are required to secure surface access rights to the land and the Company has focussed on gaining access to the Challenger Prospect as a high priority. Explorers have not had access to this ground since 1995 yet Sultan, through a respectful, open and honest approach with the local community and induvial landowners, has successfully negotiated access to this important piece of land. The Company looks forward to continuing positive negotiations with landowners and establishing itself as an important, contributing member of the local community.
Sultan Resources will continue to provide ongoing updates as it progresses exploration at the highly prospective Lake Grace Project.

| 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. |
All sampling referred to is historic – Sultan has undertaken no ground exploration programs at Lake Grace North Limited(A45226): 3815 soils 100m spacings on 400m line spacing 2kg -4mm. 3236m in 89 vertical RAB holes on 100m centres x 400 m spaced lines across anomalous zones, 3647m in 183 vertical aircore holes on 100m centres x 400m spaced lines across anomalous zones and 338.9m in 2 diamond holes. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
No comments made | |
| 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. |
Standard exploration and sampling practices used by Noth were consistent with exploration practices at the time. Other than these general remarks the author is not able to comment further. |
|
| Drilling techniques |
Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). |
Rab Aircore, RC and Diamond holes have been drilled at the project North Limited(A45226): 3236m in 89 vertical RAB holes, 3647m in183 aircore holes and 338.9m in 2 diamond holes inclined -70° @ 225°. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
Older drilling logged on paper with no assessment made of the recoveries with the results. North Limited(A45226): Diamond holes were oriented and geologically logged. Holes sampled through their entire length in 1 m intervals. RAB/Aircore drilling were sampled as 2m intervals and composited over 4 m. Samples were hand mixed and then 2kg grab sampled |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
No comments identified in any report Most drilling vertical holes on drill grids designed perpendicular to the regional grain. Actual samplingmethods off rigsnot outlined |
|
| 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. |
Insufficient information exists that would allow the author to draw a conclusion. |
|
| 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. |
All holes have been lithologically logged through their development length. None of the work is of sufficient quality or density to support resource estimation. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. |
The reviewed exploration drilling is qualitative. Quantitative work is limited to two diamond holes drilled byNorths in E70/5081. |

·Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. |
The Lake Grace Project lies in the eastern wheatbelt, approximately 250km east- southeast of Perth. The Project comprises five Exploration Licences (70/5081, 70/5082, 70/5085, 70/5095 and 70/5179) covering an area of approximately 690km2over or near the prospective Yandina Shear Zone which is known to host gold mineralisation elsewhere in the Southwest Terrane.

| Exploration done by other parties |
·Acknowledgment and appraisal of exploration by other parties. |
Previous exploration over the Lake Grace applications has been limited. Work reported was generally generative in nature and at a reconnaissance level. |
| Geology | ·Deposit type, geological setting and style of mineralisation. |
The Project lies in the Lake Grace Domain of the Southwest Terrane. It is comprised of granulite facies granitic gneisses, gneissic remnants of greenstone belts, charnokitic granites and post-tectonic granites. The greenstone rock sequences are metamorphosed to high-grade upper amphibolite to granulite facies. Structurally- controlled gold mineralisation occurs broadly as multiple, well-defined stacked elongate to ellipsoidal lodes that vary in size from 1-10 m thick, 50-150 m wide (east-west) and 50-200 m long (north-south) that have undergone post- mineralisation deformation. The gneissic package dips between 35° to 40° to the southeast and strikes 040°. The host rocks form an open synform that plunges 30° toward 120°. |
| Drill hole Information | ·A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: |
Most exploration is of a reconnaissance level, with shallow RAB or aircore geochemical drilling testing of soil geochemical anomalies |
| o_easting and northing of the_ drill hole collar |
Local grids were used to control most early exploration (pre-1990’s). These have been converted to MGA94 in most circumstances. Norths used DGPS to control local grid pattern drilling |
|
| o_elevation or RL (Reduced_ Level – elevation above sea level in metres) of the drill hole collar |
DGPS/GPS were used for most drilling. Assumed datums were used on the older work. |
|
| o_dip and azimuth of the hole_ | Almost all RAB and Aircore holes were drilled vertically. Diamond were inclined at 70° towards 225°. |
|
| o_down hole length and_ interception depth |
Down hole length of the hole is the distance from the surface to the end of the hole, as measured along the drill trace. Interception depth is the distance down the hole as measured along the drill trace. Intersection width is the downhole distance of an intersection as measured along the drill trace. |
|
| o_hole length._ | Hole length is the distance from the surface to the end of the hole, as measured along the drill trace. |
|
| ·If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
The reported work is not that of the company and much is drawn from the public reports which are under compilation. The results are informative and guiding only, as the opportunity remains early stage with the associated risks. |
|
| Data aggregation methods |
·In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. |
Given most exploration is at an early stage the reported levels of anomalous gold is appropriate, especially as the property covers rocks of a higher metamorphic grade and little is known or reported on what constitutes a significant value verses what is background for such environments. |

| ·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. |
Intercepts are reported directly and averaged over the width of the intersection, as per standard practice. The work remains very early stage and is not suitable for resource estimation. |
|
| ·The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalents used in the report | |
| Relationship between mineralisation widths and intercept lengths |
·These relationships are particularly important in the reporting of Exploration Results. |
The target type geometries for gold mineralisation are just becoming understood. The historical drilling results should be reviewed in light of this new understanding. The nature of the mineralisation is thin but commonly stacked and the drilling intercepts in numerous RAB and aircore holes seem to reflect this, but itrequiresvalidation. |
| ·If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. |
Any returned drill intercept is mostly highly anomalous and the significance to mineralisation is yet to be established at the existing drill densities. |

| ·If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
All intercepts are downhole lengths in all holes as the drilling density remains too coarse for any alternative interpretation. |
|
| Diagrams | ·Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
Appropriate maps are present within the report. The discussed drilling intersections are to provide the reader with a feel for the prospectivity of this early stage project. Gold mineralisation has been intersected in several holes but these holes exist is widely spaced drilling grids, so exploration remains in its infancy, with only a few more mature exploration programs completed by Norths Limitedforexample. |
| Balanced reporting | ·Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
The project remains very early stage, where widespread anomalism has been returned in a multitude of sample media using differing sampling techniques including drilling. The sampling density is sufficient to determine the prospectivity but to also indicate how early stage the project is. |
| 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. |
Geophysical surveys including magnetics and induced polarisation is available over some parts of the project area. |
| Further work | ·The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). |
