SIGNIFICANT NEW DRILLING RESULTS SUBSTANTIALLY EXPAND WHISTLER GOLD DEPOSIT FOOTPRINT

Recent RC drilling demonstrates important new growth opportunities along strike both to the north and south of the current 120koz resource

HIGHLIGHTS

• Successful reverse circulation drilling prior to Christmas demonstrates a significant opportunity to extend the Whistler Gold Deposit system over at least a 900m strike length.

• The Whistler South zone has been defined in shallow drilling over a strike length of at least 500m and remains totally untested at depth. Key results that currently define this gold mineralised trend are:

• GRC482: 13 metres @ 1.6g/t Au from 58 metres

• • GRC480: 5 metres @ 1.0g/t Au from 23 metres • 86MORC41: 6 metres @ 1.9g/t Au from 28 metres (Bottom of hole) • C87RB103: 6 metres @ 1.7g/t Au from 12 metres (Bottom of hole)* _(Previously reported)_

• Drilling at Whistler North has successfully intersected the mineralised structure north of the current Whistler Inferred Resource (1.7Mt at 2.23g/t for 120,000oz). The trend remains untested to the north and highlights the potential for high-grade mineralised domains down-dip.

• In addition, the drilling has confirmed a series of mafic-hosted shear zones in the hanging wall of the main Whistler trend. Significant results include:

• GRC398: 7 metres @ 1.0g/t Au from 53 metres

• • GRC397: 2 metres @ 3.6g/t Au from 62 metres • GRC400: 10 metres @ 1.0g/t Au from 43 metres • GRC454: 5 metres @ 2.1g/t Au from 25 metres • GRC402: 6 metres @ 1.5g/t Au from 43 metres • 88MRD24: 12.5 metres @ 2.2g/t Au from 128 metres*

• GRC378: 5 metres @ 2.8g/t Au from 138 metres*

• (*Previously reported)

• A program of first-pass RC drilling at the Armada Prospect, 500m north-west of Whistler, has confirmed the presence of primary structures beneath a zone of near-surface supergene mineralisation.

Gateway Mining Limited (ASX: GML) ( Gateway or Company ) is pleased to report significant new results from the recently completed reverse circulation (RC) drilling program around the Whistler Gold Deposit, within the Company’s flagship 100%-owned Gidgee Gold Project in Western Australia (Figure 1).

This drilling program was designed to undertake a first-pass assessment along strike to the north and south of the Whistler Gold Deposit to understand the potential to significantly grow the current resource (Inferred Resource of 1.7Mt at 2.23g/t Au for 120,000oz of contained gold : see ASX release dated 3 October 2019). The drilling targeted both the main granodiorite-hosted gold mineralisation and the hanging wall mafic-hosted lode system.

The drilling at Whistler formed part of a large 11,000m RC drilling campaign undertaken over several targets at Gidgee, which included both the recent discovery of an extensive zone of shallow oxide gold at Achilles and the expansion of the Montague Gold Deposit, as detailed in the Company’s ASX releases of 12 December 2019 and 20 December 2019.

KEY POINTS Whistler South

• A total of 18 holes for 2,110m of reverse circulation (RC) drilling were completed to test for continuity of gold mineralisation south of the current Whistler Resource and to provide key information on the broader structural and stratigraphic controls in the area to assist with the ongoing exploration targeting process (Figure 2).

• The South Whistler trend has now been defined in shallow positions over a strike length of at least 500m and is hosted on or near the margin of the Montague Granodiorite intrusion, which is the same setting as the Whistler Gold Deposit (Figure 3).

• The South Whistler trend is a distinctly separate gold mineralised structure and is offset approximately 100m to the east of the Whistler main structure. It is worth noting that the main Whistler structure has to date, not been closed off. Key results that currently define this gold mineralised trend are (see Table 1 and Appendix 1 for full details):

• GRC482: 13 metres @ 1.6g/t Au from 58 metres

• • GRC480: 5 metres @ 1.0g/t Au from 23 metres

• 86MORC41: 6 metres @ 1.9g/t Au from 28 metres (Bottom of hole)*

• • C87RB103: 6 metres @ 1.7g/t Au from 12 metres (Bottom of hole)*

(*Previously reported)

• The shallow gold mineralisation remains open down-dip and along strike to the north and south, and as seen at Whistler, there is considerable scope for high-grade domains to be delineated within this broader mineralised domain.

• It should be noted that mineralised intersections such as that returned in hole GRC482 (13m @ 1.6g/t Au) are common within the current Whistler Resource and can occur in close proximity to substantially higher grade zones.

• The position of the Whistler South mineralisation is in close proximity to the edge of the current optimised Whistler open pit shell and any future expansion of the resource would be easily captured.

2

Whistler North

• The 14-hole (1,975m) RC drilling program at Whistler North was designed to:

• Test the immediate northern strike extension to the current Whistler Resource (Figures 2 and 3);

• Provide key information regarding the orientation of the plunging nose of the Montague Granodiorite and confirm the geological analogy to the 3.1Moz King of the Hills deposit (owned by Red 5); and

• Provide a further test to delineate and understand the controls on the multiple hanging wall lode structures hosted within the mafic volcanic rocks.

• Significant intersections include (see Table 1 and Appendix 1 for full details):

• GRC398: 7 metres @ 1.0g/t Au from 53 metres

• GRC397: 2 metres @ 3.6g/t Au from 62 metres

• GRC400: 10 metres @ 1.0g/t Au from 43 metres

• GRC454: 5 metres @ 2.1g/t Au from 25 metres

• • GRC402: 6 metres @ 1.5g/t Au from 43 metres

• 88MRD24: 12.5 metres @ 2.2g/t Au from 128 metres*

• GRC378: 5 metres @ 2.8g/t Au from 138 metres*

• (*Previously reported)

• Drill holes GRC3978 (7m @ 1.0g/t Au) and GRC397 (2m @ 3.6g/t Au) successfully intersected the mineralised structure north of the current Whistler resource. These holes are interpreted to have intersected the top of the northern plunging high-grade domain (Figure 3). This significant zone of high-grade mineralisation remains open down-plunge to the north.

• Drill hole GRC454 (5m @ 2.1g/t Au) intersected the Whistler structure within the mafic volcanic rock stratigraphy above the granodiorite contact. The intersection of the structure with the contact of the granodiorite remains untested and is considered to be a highly prospective target (Figure 3).

• The recent drilling results from the Whistler area continue to demonstrate the emergence of a large-scale gold system within a structural corridor on or close to the margin of the Montague Granodiorite. Significant mineralisation has now been intersected over a strike length of at least 900m.

• In addition, the information gained from the drilling program continues to provide invaluable structural and stratigraphic data that is critical for ongoing exploration and resource delineation in the area.

Armada Prospect

• The Armada Prospect is located approximately 500m to the north-west of the Whistler Resource area (Figure 2). Historical drilling has intersected zones of relatively shallow, oxide gold mineralisation along what is interpreted to be the contact of the Montague Granodiorite.

• The target position is analogous with the setting of the Montague Gold Deposit, located approximately 1.6km to the south.

• The recent RC drilling program (6 holes for 605m) was undertaken to provide a first-pass test beneath the supergene gold mineralisation for primary shear zones within the mafic volcanic rock stratigraphy. Significant drilling results include (see Table 1 and Appendix 1 for full details):

• GRC412: 2 metres @ 3.4g/t Au from 68 metres and: 3 metres @ 1.3g/t Au from 78 metres

• • GRC413: 2 metres @ 1.1g/t Au from 69 metres

• GRC414: 2 metres @ 2.9g/t Au from 83 metres

• The results have confirmed the presence of bedrock shear zones within the mafic volcanic rocks on the margin of the granodiorite. This information will be integrated with geophysical datasets and follow-up exploration will be planned accordingly.

MANAGEMENT COMMENT

Gateway’s Managing Director, Mr Peter Langworthy, said the significant new results from wide-spaced reconnaissance drilling both to the north and south of the 120,000oz Whistler Resource provided further strong evidence of the potential for a large-scale gold system along the margin of the granodiorite.

“The new results, combined with some significant advances in our geological thinking over the Christmas/New Year period, amount to a really exciting breakthrough at Whistler, demonstrating that it has excellent potential to grow substantially, both to the north and south.

“We have confirmed the presence of the new Whistler South mineralised structure over a strike length of 500m, and it remains totally untested at depth. Meanwhile, to the north of the Whistler Resource we have now located the strike extension of the structure that can now be targeted with the next phase of drilling – more than doubling the overall scale of the system to at least 900 metres.

“In addition to the granodiorite-hosted mineralisation, we are also now delineating and understanding the significance of the multiple mafic-hosted hanging wall lodes. We are confident that these will develop into a significant zone of mineralisation that is strongly complementary to the main Whistler Resource.

“It is worth noting that all these positions are in close proximity to the current Whistler optimised pit shell, and any expansion of this would easily incorporate these new areas of mineralisation.

“Looking ahead, we will finalise the reporting of the remaining results from the drilling programs completed in December, including the air-core drilling program that comprised first-pass testing of a number of completely new areas.

“We will then prioritise and plan our next exploration steps, taking into the account the significant advances we have made recently in terms of expanding the potential at Whistler and Montague, defining a significant new zone of shallow oxide mineralisation at Achilles and improving our understanding of a number of other emerging prospects.

“Recent drilling has once again reinforced the very large and prospective nature of the Gidgee Gold Project. Our focus this year will be to find the quickest and most cost-effective way of unlocking substantial new discoveries while at the same time rapidly building our resource inventory from the strong base we have already established.”

APPENDIX (1): 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 pulverized 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.	• Gateway RC drilling (GRC prefix) - 2kg - 3kg samples were split from dry 1m bulk samples. The sample was initially collected from the cyclone in an inline collection box with independent upper and lower shutters. Once the metre was completed, the drill bit was lifted off the bottom of the hole, to create a gap between samples, when the gap of air came into the collection box the top shutter was closed off. Once the top shutter was closed, the bottom shutter was opened, and the sample was dropped under gravity thorough a Metzke cone splitter. Once drilling reached fresh rock a fine spray of water was used to suppress dust and limit the loss of fines thorough the cyclone chimney. A second 2kg-3kg sample was collected at the same time the original sample. This sample has been stored on site. These duplicate samples have been retained for follow up analysis and test work. The bulk sample of the main ore zone was discharged from the cyclone directly into green bags. • The bulk sample from the waste was collected in wheelbarrows and dumped into neat piles on the ground. • During the sample collection process, the cone split, original and duplicate calico samples and the reject green bag samples were weighed to test for bias’s and sample recoveries. The majority of the check work was undertaken through the main ore zones. • Field duplicates were collected at a ratio of 1:20 through the mineralised zones and collected at the same time as the original sample through the B chute of the cone splitter. OREAS certified reference material (CRM) was inserted at a ratio of 1:20 through the mineralised zone. The grade ranges of the CRM’s were selected based on grade populations and economic grade ranges. • Historic Gateway RAB drilling (GRB – prefix) was conducted by Bordec Drilling. All analysis was completed by Genalysis Laboratories, Perth. Submitted samples comprised 2kg speared parent samples which were subjected to total preparation. Au by B/ETA to 1ppb. Ag,As Co,Cu,Ni Sb and Zn by B/AAS to 1ppm. Historical Drilling: All information referred in this report not collected in this current program 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 analysedfor Au by AAS technique with resultsgreater than 0.5ppm _

Criteria	JORC Code explanation	Commentary
		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 were sent to Pilbara Laboratories and Australian Assay Laboratories for gold by fire assay on 50g charge.
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.).	• RC – Challenge Drilling drill rig was used. The rig consisted of a Schramm truck mounted RC rig with 1150cfm x 350psi on board compressor, an Airsearch 1800cfm x 900psi on board Booster, and a truck mounted Sullair 900cfm x 350psi auxiliary compressor. • RAB Drilling – Bordec Drilling completed all of Gateway’s historic RAB drilling programs Historical Drilling: All information referred in this report not collected in this current program 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.

Section 2 Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section.)

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.	• M57/48 and M57/99. Both mining tenements are held under Gateway Mining Ltd 100%. • No Native Title claims are lodged over the tenements
Exploration done by other parties	• Acknowledgment and appraisal of exploration by other parties.	• Gold was discovered in the district during the gold rush era, first records of gold won from small-scale, high-grade workings include the Montague Mining Centre (1904-13). Renewed interest in the late 1960's included base metal exploration carried out within exposed stratigraphy of the Montague Ranges (Bungarra Ranges), exploration interest that broadened with the release of the Sandstone 1:250,000 aeromagnetic sheet in 1970 resulting in the staking of favourable magnetic anomalies by exploration companies. • Early explorers in the Montague Ranges included Anaconda Australia Inc. (1966- 67), followed by International Nickel Australia (1971-75) evaluating a Gabbro - banded differentiated basic complex believed prospective for copper and/or nickel such as the Dulith Gabbro, USA. Strong geophysical and mineralised anomalism was encountered, however, copper-zinc enrichment was also encountered in adjacent felsic stratigraphy at Ed's Bore prospect, which was followed-up by CRA Exploration (1983-1990) to intersect polymetallic VMS enrichments at Bevan prospect (not substantively pursued). • At Montague, Western Mining Corporation (1976) conducted investigations for copper and gold including soil sampling and IP surveying, which was followed by CRA Exploration (1984-89) working concurrently with AMOCO Minerals Australia Company (1984) and Clackline Refractories Ltd (from 1985 - to later become Herald Resources) assessing/purchasing historic mine areas from Mr W.J. Griffiths of Sandstone. RAB drilling penetrating transported cover resulted in the virgin discoveries of NE Pit by AMOCO and Whistler deposit by CRA. Later noted explorers included Dalrymple Resources NL (1987-1990) intersecting gold at the Armada (Twister) prospect, and Arimco Mining (1990-98) intersecting gold at Lyle prospect, Victory West prospect, and copper at The Cup prospect (not substantively pursued). • The Montague Mining Centre produced approximately 150,000oz of gold commencing in 1986 at Caledonian and NE Pits (Clackline), and continued at Montague Boulder from 1988 (Herald), and was to close in 1993 after completion of the Rosie Castle open cut (Herald). Whistler open cut was mined from November 1990 (Polaris Pacific NL) and ore toll treated through the Herald mill. Little attention waspaid to mineralisation other thangold. GatewayMininginjoint

Geology	• Deposit type, geological setting and style of mineralisation.	• Gateways’s Gidgee Project is located in the Gidgee district in the Archean Yilgarn Craton of Western Australia approximately 630km NE of Perth and 70km north from the township of Sandstone on the eastern central portion of the Gum Creek Greenstone Belt, of the Southern Cross Province. Metamorphic grade of the Gum Creek Greenstone Belt is estimated to be low-grade greenschist facies. Project lithology includes basalt/ash tuff/dolerite/gabbro, the Montague Granodiorite sub-volcanic intrusion (calc-alkaline - FI), dacite volcanic flow/s (FI), volcaniclastic sequences of felsic composition and epiclastic conglomerates, ultramafic intrusives and external orogenic granite plutons. Key regional characteristics of a Volcanic Arc Extensional Basin include calc-alkaline bimodal volcanic sequences associated with extensive iron formations. Later ENE-WSW orogenic compression event is characterised by NNW regional scale faults/unconformities, NNW shearing and folding, slaty cleavage has developed within sediments near a tight syncline fold closure within the NE area of the project.
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.	• Exploration drill results from recent drilling, and associated details are contained in Table 1 of this release. Historic intersections reported in Table 2 have been previously released by Gateway in various ASX releases, which can be accessed on the Gateway Mining Ltd website.
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. • 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	• Significant intersections are calculated as a minimum of 1m greater than 0.5g/t Au with a maximum of 2m of internal dilution • No high-grade cut-off has been applied

	detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated.
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 known’). _	• Drill lines were orientated perpendicular to the perceived strike of the mineralised structure. Inclined RC holes (-60°) are perpendicular to the dip of the mineralised structure creating minimal sampling bias. The vertical RC holes are around 20-30° off being perpendicular to the dip in the mineralised structure creating a minimal sampling bias.
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 included in the announcement
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 considered to be a balanced report with a suitable cautionary note.
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.	• 3D gravity and airborne magnetic data is currently being modelled with subsequent RC and aircore drilling being used to test new regional exploration targets
Further work	• The nature and scale of planned further work (eg 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.	• Step-out RC drilling down dip and along strike of high grade gold intercepts.
