ASX Announcement: 12 December 2019

STRONG ZONES OF SHALLOW OXIDE GOLD AT ACHILLES PROSPECT

RC drilling defines significant near-surface mineralisation, confirming strong exploration upside at the Gidgee Gold Project

HIGHLIGHTS

• Reverse Circulation (RC) drilling at the recently defined Achilles Prospect has highlighted significant, near-surface mineralisation over a +400m corridor immediately north of the historically mined Rosie Castle open pit. Significant results include:

• GRC446: 21 metres @ 2.1g/t Au from 32 metres (including 7 metres @ 5.2g/t Au)

• GRC447: 13 metres @ 3.4g/t Au from 5 metres (including 3 metres @ 12.5g/t Au)

• GRC430: 11 metres @ 3.0g/t Au from 32 metres

• GRC432: 7 metres @ 2.2g/t Au from 60 metres

• GRC435: 6 metres @ 3.8g/t Au from 17 metres

• GRC437: 10 metres @ 3.8g/t Au from 31 metres

• GRC443: 6 metres @ 2.1g/t Au from 22 metres

• GRC426: 19 metres @ 1.3g/t Au from 29 metres

• Significant zones of stockwork mineralisation have also been intersected wholly within the granodiorite.

• The Achilles mineralised corridor remains untested for approximately 600m north towards the historically mined NE Caledonian open pit.

• Additionally, drilling remains limited south of the Rosie Castle open pit for approximately 4km.

• Drilling completed to date is shallow, with the majority of the intersections either oxide or transitional (partially oxidized) in nature.

• Expanded 11,000m RC drilling program now complete, with a substantial number of assay results expected over the coming weeks.

Gateway Mining Limited (ASX: GML) ( Gateway or Company ) is pleased to advise that it has defined a significant zone of shallow oxide gold mineralisation over a strike length of at least 400m at the Achilles Prospect, part of its 100%-owned Gidgee Gold Project , Western Australia (Figure 1).

The Company has received significant Reverse Circulation ( RC ) drilling results from the Achilles Prospect which are reported in this announcement, marking a strong start to its recently completed 11,000m RC drilling program.

A substantial number of assay results are outstanding from the program, and are expected to be progressively received and reported over the coming weeks.

KEY POINTS

• A total of 33 RC holes for 3,039m were completed over a strike length of approximately 400m (Figure 2) at the Achilles Target.

• Drilling at Achilles was designed to test the granodiorite-mafic contact area over a broad strike length extending north from the historically mined open pit at Rosie Castle, which was centered on this style of mineralisation. Previous exploration targeting the continuation of this structure was relatively limited in scope. Additionally, geological interpretation by Gateway has highlighted a series of potential thrust repeats of this contact in the area, which forms the basis of the Achilles Prospect. No systematic exploration has previously been carried out at the Achilles Prospect to test this, but there are indications of other mineralised surfaces in existing historical data (e.g. at S-Bend).

• With the exception of three holes, all of the holes drilled by Gateway as part of the current program intersected significant gold mineralised structures. The results both confirmed and extended the zones of mineralisation intersected previously in historical RC drilling.

• Significant new drilling results at Achilles include (see Table 1 and Appendix 1 for full details):

• GRC446: 21 metres @ 2.1g/t Au from 32 metres (includes 7 metres @ 5.2g/t Au)

• • GRC447: 13 metres @ 3.4g/t Au from 5 metres (includes 3 metres @ 12.5g/t Au) • GRC430: 11 metres @ 3.0g/t Au from 32 metres

• GRC432: 7 metres @ 2.2g/t Au from 60 metres

• GRC435: 6 metres @ 3.8g/t Au from 17 metres

• • GRC437: 10 metres @ 3.8g/t Au from 31 metres • GRC443: 6 metres @ 2.1g/t Au from 22 metres • GRC426: 19 metres @ 1.3g/t Au from 29 metres

▪ Previously reported historical Achilles intersections include (see Table 2 and Appendix 1 for full details):

• GRC085: 2 metres @ 14.1g/t Au from 68 metres

• • GRC104: 2 metres @ 12.8g/t Au from 82 metres • GRC107: 10 metres @ 2.0g/t Au from 26 metres • GRC108: 4 metres @ 5.6g/t Au from 45 metres • GRC109: 3 metres @ 4.3g/t Au from 65 metres • GRC111: 6 metres @ 2.2g/t Au from 22 metres • GRC114: 10 metres @ 2.5g/t Au from 17 metres • GRC116: 17 metres @ 1.7g/t Au from 20 metres

2

• GRC117: 6 metres @ 2.9g/t Au from 50 metres

• GRC118: 15 metres @ 2.9g/t Au from 43 metres

• GRC127: 2 metres @ 12.4g/t Au from 119 metres

• GRC177: 3 metres @ 9.3g/t Au from 87 metres

• • WRC011: 2 metres @ 6.0g/t Au from 88 metres • GRB1551: 8 metres @ 7.0g/t Au from 25 metres • GRB1450: 10 metres @ 9.9g/t Au from 15 metres

• Drilling to date remains relatively shallow and, as such, the majority of intersections are either oxide or transitional (partially oxidized) in nature.

• The mineralisation is interpreted to be best developed where multiple, sub-vertical structures within the mafic volcanic rocks intersect the flat-lying thrust contact on the margin of the granodiorite intrusion (Figure 3). Down-dip of these intersection positions, the mafic-hosted structures are typically narrower and more discrete, with a strong component of high-grade gold.

• In addition to these main zones of mineralisation, widespread zones of stockwork mineralisation have also been intersected wholly within the granodiorite.

• These observations are consistent with the geological model developed by Gateway.

• This program of RC drilling has demonstrated the unreliability of historical RAB drilling in evaluating the presence and tenor of mineralisation present in the bedrock. As a result, it is considered that wide areas of prospective host rocks have not been effectively tested by previous exploration.

• Ongoing assessment of the greater Achilles area confirms the emerging potential of the wider target (Figure 4). Specific areas that require ongoing assessment include:

• The corridor north of the current drilling, which remains untested for approximately 600m towards the historically mined NE Caledonian open pit. The continuation of the host structure is easily visible in geophysical data (see Figure 4).

• The sub-parallel S-Bend trend, as defined in magnetic data, is present over a strike length of at least 800m.

• An interpreted thrust repeat, that sees the same structure and stratigraphy replicated to the west. Limited shallow drilling demonstrates this to be prospective but untested over a strike length of 3.6km.

• South of the Rosie Castle open pit, where the interpreted continuation of the host structure remains only sporadically tested for approximately 4km.

NEXT STEPS

Gateway continues to receive assay results from the recently completed RC program. These results will be compiled and interpreted in line with the existing database, and utilised to assess the potential for extensions to existing Mineral Resources at the Whistler and Montague Deposits, as well as areas for further drilling to outline the potential for additional Mineral Resources.

In addition, Gateway is embarking on a significant program of integrating all its available datasets – drilling and surface geochemistry, structural interpretation, as well as aeromagnetic, ground gravity and sub-audio magnetic (SAM) geophysics in order to assess the project-wide prospectivity.

The continued improvements in the geological understanding of the Gidgee Project being developed by Gateway has highlighted the Project’s excellent potential to host a significant gold discovery. The abundance of mineralisation identified to date from limited work and historical mining activities, with gold developed in a multitude of geological and structural settings, appears to support this.

This ongoing work is aimed at not only assisting in further improving the understanding of existing mineralised areas, but also in developing new targets for significant gold mineralisation, in order to unlock the Project’s true potential.

MANAGEMENT COMMENT

Gateway’s Managing Director, Mr Peter Langworthy, said the early success of the recently completed 11,000m drilling program in defining a significant zone of shallow oxide gold mineralization at Achilles provided further evidence of the substantial long-term growth potential at the Gidgee Gold Project.

“This program of RC drilling is a great starting point for our evaluation of the Achilles Prospect. We have already defined a significant zone of near-surface mineralisation over a strike length of at least 400m, including a large

5

component of oxide and transitional mineralisation, and we have significantly improved our understanding of the key controls on the mineralisation which can be applied in a wider context,” he said.

“Ultimately though we see the Achilles area as part of a major gold system that requires ongoing systematic programs of exploration. Our growing understanding of the controls on the gold mineralisation, combined with the quality of our datasets we now have available to us, means that we are now moving a lot closer towards unlocking the broader potential of this hugely prospective but remarkably under-explored project.

“All of the evidence we are accumulating is pointing towards the potential for a very large gold system on these tenements, and we feel that we are now getting a lot closer to pin-pointing its overall dimensions and identifying the areas of significant economic interest.”

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 pre-fix) - 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 infresh 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 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. 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 drillingrigspecifications.
Drill sample recovery	• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximize sample recovery and ensure representative nature of the samples. • 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.	• During the RC 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. From this process showed that the majority of ore grade samples had recoveries greater than 80% • 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. • At the end of each metre the bit was lifted off the bottom to separate each metre drilled. • The majority of samples were of good quality with ground water having minimal effect on sample quality or recovery. • From the collection of recovery data, no identifiable bias exists.

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.

Criteria	JORC Code explanation	Commentary
		Little attention was paid to mineralisation other than gold. Gateway Mining in joint venture with Herald Resources continued exploration of the Montague Mining Centre, Gateway also targeting poly-metallic intrusion related - VMS models in the district from 2006. • Airport, Airport Sth, S Bend, Rosie Nth, Rosie Sthmineralisation was discovered by Gateway Mining between 2007 and 2011 in RAB drilling and later defined by RC drilling.
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.	• Historic Exploration drill results are contained with Table 1
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.	• The lower grade cut-off is set at 0.1g/t. There is no maximum grade cut-off applied to these set of exploration results.

17

Criteria JORC Code explanation	Criteria JORC Code explanation	Commentary
	• 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.
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 mineralized structure. Inclined RC holes (-60°) are perpendicular to the dip of the mineralized 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 and sections 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
