MARCH 2018 QUARTERLY ACTIVITIES AND CASH FLOW REPORT

Pivotal quarter for Gateway as it expands its asset base, completes a $3.8m capital raising and embarks on a focused gold exploration strategy in WA

Highlights:

• Acquisition of Omni Projects Pty Ltd successfully completed, resulting in a significant expansion of the Company’s exploration portfolio in WA.

• Gateway resets the Company’s strategic direction based on focused gold exploration at the expanded Gidgee Gold Project.

• Appointment of experienced, well-credentialed geologist and project developer Peter Langworthy as Managing Director of the Company.

• Fully subscribed $3.8m (before costs) capital raising completed, resulting in the introduction of several new strategic investors.

• • Preparations advanced for the Company’s maiden drilling campaign, which is set to begin at the Gidgee Gold Project in April 2018.

ACQUISITION OF OMNI PROJECTS

During the quarter, the Company announced that it had entered into a Sale and Purchase Agreement ( Agreement ) whereby it would acquire all of the issued capital in Omni Projects Pty Ltd ( Omni Projects ) from its sole shareholder Omni GeoX Pty Ltd ( Omni GeoX ) ( Acquisition ).

This followed the heads of agreement with Omni Projects announced on 22 December 2017.

On 16 March 2018, the Company announced that the purchase of Omni Projects had been completed following the satisfaction of all conditions precedent under the Agreement.

The acquisition of Omni Projects has allowed the Company to consolidate and expand its position at the Gidgee Gold Project in Western Australia, as well as creating opportunities for exposure to a series of exploration projects adjacent to major gold deposits across Western Australia.

As a result of the successful completion of the acquisition, the Gidgee Project now comprises of a consolidated area of 600km[2] covering the southern extension of the Archaean aged Gum Creek Greenstone Belt.

The Company’s new exploration strategy will be driven by the Company’s newly appointed Managing Director, Mr Peter Langworthy, a well-credentialed and highly experienced geologist and mining executive with a strong track record of value-creation in the Australian mining and exploration industry.

GIDGEE GOLD PROJECT

Gateway’s Gidgee Gold Project is located approximately 70km north of the township of Sandstone, Western Australia. The Gidgee Project now comprises a consolidated area of ~600km[2] covering the southern extension of the Archaean aged Gum Creek Greenstone Belt.

The project is easily accessible from Perth via major sealed and well-formed gravel roads. The town of Sandstone provides limited logistics support and the project is centrally located within a ~120km radius of six operational gold treatment facilities.

Target Summary

As announced on 1 March 2018, the primary target within the Gidgee Gold Project is the highly deformed and mineralised western margin of the Montague Granodiorite ( MGD ) (Figure 2).

A regional-scale fault system is interpreted to have interacted with the MGD and has controlled both the shear zone related mineralisation on the margin of the MGD and within the enveloping mafic volcanic rock package, and the broader zones of stockwork gold mineralisation internal to the MGD.

Geochemical studies also suggest that distinct early-stage alteration imparted during intrusion of the MGD has been critical to creating chemical and physical conditions that have played a part in focusing the overprinting gold mineralisation.

Exploration Strategy

On 1 March 2018, the Company announced that its primary exploration strategy at the Gidgee Gold Project will be to rapidly delineate the size and quality of the gold mineralised system that has been identified along the western margin of the MGD. This high-priority target extends for a strike length of at least 8km.

This objective will be achieved by executing focused programs of RC drilling on the identified high-priority targets, accompanied by systematic aircore drilling to test the true potential of the contact of the MGD. Initial programs will comprise ~9,000m of RC drilling, followed by a ~10,000m program of aircore drilling.

Resource evaluation programs will be instigated at the appropriate time, when the resource size potential is considered large enough. Other key upcoming activities will include:

• Detailed evaluation and targeting of the stockwork mineralised targets;

• Evaluation and initial testing of the eastern margin of the MGD; and

• Developing an understanding of the VHMS-system that has been identified in the stratigraphic succession surrounding the MGD.

The key targets that will be the initial focus of the Company’s planned programs of exploration comprise:

• Whistler Target: Located on the northern margin of the MGD, where the contact between the MGD and the enveloping mafic volcanic rocks is interpreted to be plunging to the north. There is a priority high-grade target beneath the shallow, historical oxide open pit mine. Drilling to date has identified a strong high-grade domain and demonstrates that the mineralisation remains open in all directions. Excellent potential remains for significant nearsurface oxide mineralisation. The target has potential for parallel shears zones both within the MGD and the surrounding mafic volcanic rocks.

• Montague Target: Located on the western margin of the MGD, where a series of shear zones and associated stockwork zones control the gold mineralisation. There is a priority high-grade target beneath the shallow (oxide), historical Montague-Boulder open pit mine. The target has excellent potential for expansion of near-surface oxide mineralisation along strike and for high-grade primary mineralisation at depth and along strike.

3

• Caledonian Target: The target represents a different style of gold deposit when compared to Whistler and Montague. The mineralisation has developed within a distinct, regionally extensive shear zone and is hosted by mafic volcanic rocks. Old prospecting shafts and pits extend for at least 3km along the Caledonian Trend. There is a priority high-grade target beneath the shallow (oxide) historical Caledonian open pit mine. High-grade shoots can be defined within a broad mineralisation zone over at least 1km. The shear zone along the strike of the historical pit presents numerous opportunities to delineate significant gold mineralisation.

Figure (2): Gidgee Gold Project Interpreted Geology

Subsequent to the reporting period, the Company announced on 19 April 2018 that it had commenced its maiden drilling program at the Gidgee Gold Project, where it will begin testing a series of high-priority targets.

The initial RC drilling program will target the high-priority Whistler, Montague and Caledonian targets, where historical drilling has consistently demonstrated that the high-grade mineralised structures remain open beneath the shallow, historical oxide open pits.

4

The planned RC drilling program will comprise approximately 9,000m (~60 holes), however consideration is currently being given to bringing forward a component of diamond drilling to provide important structural data at each of the targets as well as samples for preliminary metallurgical testwork.

The 10,000m AC drilling program will commence once the RC and diamond drilling is complete. The overall program will take ~2 months to complete and significant results will be reported on a progressive basis as they come to hand.

REGIONAL WA PROJECTS

Successful completion of the Acquisition has provided exposure to a portfolio of six exploration projects located in the Yilgarn, Bryah and Pilbara districts of Western Australia ( Regional Projects ).

The Regional Projects cover an approximate area of 1,039km[2] and comprises 15 Exploration Licenses and applications. The majority of the projects are located adjacent to major mineralised systems and cover highly prospective structural trends.

The Regional Projects comprise of:

• Bryah Basin Project: The Bryah Basin Project provides a large, consolidated profile in the Bryah Basin, a Proterozoic-aged volcano-sedimentary rift basin that is highly prospective for gold and copper-gold VHMS mineralisation. The project is host to a number of important deposits including the DeGrussa and Monty copper-gold deposits (Sandfire and Talisman) and the Fortnum gold deposit (Westgold).

• Edjudina Project: The Edjudina Project is located in the highly mineralised Eastern Goldfield Province of the Yilgarn Craton and is considered prospective for gold and nickelcopper mineralisation. The project covers a strike extent of approximately 29km within the Linden Terrain east of the Pinjin Fault, and covers a north-northwest trending sequence of prospective greenstone lithologies that are immediately along strike of Matsa Resources Limited’s Fortitude Gold Project, where mining recently recommenced with a trial mining study. The area is also subject to significant exploration interest from a number of major resource companies including St Barbara Limited, Saracen Minerals Holding Limited and AngloGold Ashanti Australia Limited.

• Cunyu Project: The Cunyu Project is located on the eastern margin of the Proterozoic-aged Yerrida Basin and is targeting a Proterozoic mafic-ultramafic intrusive complex of that is considered prospective for nickel-copper and PGE-type deposits. In addition to this, the project is interpreted to lie on a similar stratigraphic horizon to the Magellan lead-zinc deposit (owned by LeadFX Inc.), located approximately 80km to the south.

• Edna May Project: The Edna May Project is located on the northern end of the Archeanaged Westonia Greenstone Belt, which is part of the larger Southern Cross Greenstone Belt. The project is immediately along strike from Ramelius Resources’ Edna May gold mine. The host greenstone belt and regional structure that controls the Edna May mine mineralisation is interpreted to persist through the project area, as evidenced by the presence of gold mineralisation intersected in historical drilling.

5

• Southern Cross Project: The Southern Cross Project includes over 20km of prospective greenstone located at the northern end of the highly endowed Southern Cross Greenstone Belt. The belt is an Archaean-aged package of mafic-ultramafic volcanic and sedimentary rocks, and is considered highly prospective for significant gold mineralisation as well as komatiite hosted nickel sulphide, VHMS and lithium deposits.

• Sylvania Project: The Sylvania Project covers part of the Sylvania Inlier, an Archaean-aged cratonic block on the southern margin of the Pilbara Craton. The project is considered prospective for gold mineralisation and is relatively untested by systematic modern exploration techniques. Although at an early stage, it has been recognized that conglomerate stratigraphy, which is potentially prospective for palaeo-placer gold mineralisation, is present across the project.

CAPITAL RAISING

On 16 March 2018, the Company announced that it successfully raised a total of $3.8 million (before costs) to underpin its explorations programs at the Gidgee Project.

The Company completed the capital raising through its recent non-renounceable entitlement issue inviting existing shareholders to participate ( Entitlements Issue ). Professional and Sophisticated investors participated in the shortfall.

The Company received strong support from existing shareholders and new investors. As a result of the Entitlements Issue, the Company issued a total of 318,422,962 shares and 63,684,593 unlisted options.

BOARD CHANGES

On 15 March 2018, the Company announced the appointment of highly experienced Australian mining executive Mr Peter Langworthy as Managing Director to drive the Company’s new gold strategy.

The appointment followed the Company’s recently announced strategic refocus on the expanded and consolidated ground position at its flagship Gidgee Project.

Subsequent to the reporting period, the Company announced on 12 April 2018 that it further strengthened its board with the appointment of Ms Debbie Fullarton and Mr Scott Brown as nonexecutive Directors and the appointment of Mr Kar Chua as Company Secretary.

The appointments bring additional corporate and strategic expertise to the board which will be invaluable as the Company progresses its previously announced WA gold strategy.

Yours faithfully

Peter Langworthy Managing Director Gateway Mining Limited

APPENDIX (3): SIGNIFICANT DRILLING INTERSECTIONS JORC Code, 2012 Edition Table 1

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. • 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 (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.	All information referred in this report has been accessed through verifying historical company reports and/or available digital databases. Diamond Drilling:HQ3 and NQ core drilled in fresh rock. Core orientated and mineralised noted and marked for cutting. Sample lengths sampled on 0.5 to 2m intervals and cut to half-core sub-sample collected. Samples were analysed for Au by AAS technique with results greater than 0.5ppm Au re-assayed by Fire Assay. Assays >3g/t Au re-assayed by Screen Fire Assay. This methodology was applied to account for a recognized coarse gold component within the mineralised zones. RC Drilling:Samples were collected on 1m intervals, riffle split and 5m composite samples prepared for assay. Re- assays were undertaken on selected 1m samples. Samples sent to ALS in Perth, for 3kg pulverisation for production of homogenous 50g or 30g charge for Au fire assay, multi elements also analysed.
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.).	All information referred in this report has been accessed through verifying historical company reports and/or available digital databases. Diamond Drilling:RC percussion or HQ3 pre-collars were drilled to fresh rock. NQ core drilled for remainder of holes. No details available on drilling rig specifications. RC Drilling:RC percussion drilled as pre-collars to fresh rock. No details available on drilling rig specifications.
Drill sample recovery	• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples.	All information referred in this report has been accessed through verifying historical company reports and/or available digital databases.

	• 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.	Diamond Drilling:Recoveries in fresh rock are recorded as being satisfactory and that no inherent bias has been introduced from drilling or sampling techniques. RC Drilling:There are no records available that capture information on drilling recoveries. Typically a minimum 3kg sample was provided to the laboratory for assay. Samples considered fit for purpose.
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. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. • The total length and percentage of the relevant intersections logged.	All information referred in this report has been accessed through verifying historical company reports and/or available digital databases. Reverse circulation and Aircore chips were washed and stored in chip trays in 1m intervals for the entire length of each hole. Chips were visually inspected and logged to record lithology, weathering, alteration, mineralisation, veining and structure. Records of samples being wet or dry were taken. Diamond core was presented and stored in industry standard core boxes. The core was orientated and core loss noted. Data on rocktype, deformation, colour, structure, alteration, veining, mineralisation and oxidation state were recorded. RQD, magnetic susceptibility and core recoveries were recorded. Logging is considered both qualitative and quantitative or semi-quantitative in nature. The logging information is considered to be fit for purpose.
Sub- sampling techniques and sample preparation	• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled.	All information referred in this report has been accessed through verifying historical company reports and/or available digital databases. RC samples were split using a riffle splitter. 1m samples were collected and 5m composites prepared for assay. Re-assays were undertaken on selected 1m samples. Typically 3kg samples were submitted to the assay laboratory. Only minor numbers of samples are recorded as being wet. QA/QC data is not currently available. Sampling processes are considered fit for purpose. Diamond core was presented and stored in industry standard core boxes. The core was orientated and core loss noted. Once logged the core was marked up for sampling ranging from 0.5m to 2.0m largely matching geological contacts. Half core samples were collected and submitted to the assay laboratory. Samples were analysed for Au by AAS technique with results greater than 0.5ppm Au re-assayed by Fire Assay. Assays >3g/t Au re-assayed by Screen Fire Assay. This methodology was applied to account for a recognized coarse gold component within the mineralised zones.

All samples were assayed at either Analabs or ALS in Perth. Samples were analysed for Au by AAS technique with results greater than 0.5ppm Au re-assayed by Fire Assay. Assays >3g/t Au re-assayed by Screen Fire Assay. This methodology was applied to account for a recognized coarse gold component within the mineralised zones. QA/QC data is not currently available. Sampling processes are considered fit for purpose.
Verification of sampling and assaying	• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data.	All information referred in this report has been accessed through verifying historical company reports and/or available digital databases. Logging and sampling were recorded directly into a Stratalog T500 digital logging unit. All drilling information is currently stored in a Gateway Access database. All information has been plotted on section and in plan to match against neighbouring holes and determine likely validity of the data QA/QC data is not currently available. Sampling and assay data are considered fit for purpose.
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. • Specification of the grid system used. • Quality and adequacy of topographic control.	All information referred in this report has been accessed through verifying historical company reports and/or available digital databases. A truncated AMG grid was established across the project area and hole collars were measure from fixed survey pegs. These collar locations have been validated using detailed aerial photography. Downhole surveys were undertaken with an Eastman single shot camera on intervals ranging from 30 to 50m. Location data is considered fit for purpose.
Data spacing and distribution	• Data spacing for reporting of Exploration Results. • 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. • Whether sample compositing has been applied.	All information referred in this report has been accessed through verifying historical company reports and/or available digital databases. Please See Table 1 for Results Drilling at the Whistler, Montague and Caledonian targets have been drill tested in various spacings. Typically immediately below the historial open pit mines the spacing is a nominal 25 x 25m and as the drilling moves deeper and along strike expands to 25 x 50m and 50 x 50m.
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. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.	All information referred in this report has been accessed through verifying historical company reports and/or available digital databases. Drilling directions at Whistler, Montague and Caledonian targets have been drilled perpendicular to strike (90-270) and in the across dip direction in most cases.

15

The majority of holes have been drilled at a 60 to 90 degree dip and intersected the mineralisation at an appropriate angle. In some cases reverse angled holes have been completed to test for short range controls on the gold mineralisation. The orientation of the drilling is suitable for the mineralisation style and orientation of the mineralisation at the Whistler, Montague and Caledonian Targets.

Section 2 Reporting of Exploration Results

Criteria	JORC Code explanation	Commentary
Mineral tenement and land tenure status	• 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 security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.	See Appendix (1) The Gidgee Project is located on tenements: M57/485,E57/793 and M57/429 (GML 75%, Estuary Resources NL 25%). E57/405, E57/874, E57/945, E57/87, E57/888, E57/823, E57/824, E57/688, E57/687, E57/417, M57/48, M57/98, M57/99, M57/217, E57/807, E57/876, E57/1004 and E57/1005 (GML 100%).

Historically there have been claims. E57/0888 and M57/0098 are affected by Crown Water Reserve 10203. E57/0405, E57/0687, E57/0793, E57/0823 and E57/1005 are affected by CPL/25, Lake Mason P/L 3114/551 (former pastoral lease purchased by the Department of Conservation and Land Management / Department of Biodiversity, Conservation and Attractions E57/0417, E57/0687, E57/0688, E57/0793, E57/0807, E57/0823, E57/0824, E57/0874, E57/0875, E57/0876, E57/0888, E57/0945, E57/1004, M57/0048, M57/0098, M57/0099, M57/0217, M57/0429, and M57/0485 are affected by Crown Reserve 9959 No other known impediments exist to operate in the area.
Exploration done by other	• Acknowledgment and appraisal of exploration by other parties.	Prior to Gateway, the project area was held by a succession of companies,which has been documented back to the mid-

16

parties		1980’s. Key work was undertaken by CRA Exploration and Herald Resources Ltd. All work has been assessed and is considered fit for purpose.
Geology	• Deposit type, geological setting and style of mineralisation.	The mineralisation style at the Gidgee Project is an Archaean lode gold deposit. The mineralisation is controlled by a major shear array that has penetrated the eastern margin of the Montague Granodiorite. The mineralisation is shear zone controlled with associated stockwork mineralisation. Based on the historically available data the mineralisation is typified as being free milling.
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: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. • 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.	Please See Table 1 for Results
Data aggregation methods	• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. 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 clearly stated.	Assays were completed on individual samples and the reported intersections are reported as weighted average Downhole widths. No top cuts have been applied as the intersections are typically not biased by individual assays.
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 _(e.g. ‘down hole length, true width not known’). _	The drilling is typically perpendicular or at a high angle to the mineralisation. The reported intersections are reported as weighted average Downhole widths.
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.	The diagrams in the report provide sufficient information to understand the context of the drilling results.
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 accompanying document is a balanced report with a suitable cautionary note.
Other substantive exploration	• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results;	Historical geophysical, geochemical and regional drilling datasets are available and have been utilized to varying degrees in the assessments to date. These have not

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). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.	Further Drilling program have been designed to follow up the current drilling to further define the mineralised zone. Industry best practice will be applied.
