ASX Announcement: 3 October 2019

MAJOR NEW EXPANSIONARY DRILLING PROGRAMS UNDERWAY AT GIDGEE GOLD PROJECT FOLLOWING MAIDEN RESOURCE

~16,000m of RC and air-core drilling underway to test multiple exploration targets, including newly-defined Exploration Target at the Achilles Prospect

HIGHLIGHTS

• Major new drilling program commences at the 100%-owned Gidgee Gold Project in WA.

• ~16,000m of reverse circulation and air-core drilling has commenced[1] . Drilling is targeting:

• The next stage of resource expansion at both the Whistler and Montague Gold Deposits following the maiden Mineral Resource of 3.4Mt at 2.2g/t Au for 240,000oz of gold[2] , which was announced earlier today;

• Conversion of a newly-defined Exploration Target for the Achilles Target (see below) into a JORC 2012 compliant Mineral Resource;

• A series of positions along the margin of the Montague Granodiorite that have been targeted using the recently acquired detailed gravity dataset[3] .

• An Exploration Target of 1.2 Mt to 3.4 Mt at 2.3g/t to 3.4g/t comprising between 88,000oz and 370,000oz has been estimated for the Achilles Prospect.

• The Achilles Exploration Target is in addition to the Maiden Mineral Resource for the Whistler and Montague Gold Deposits of 3.4Mt @ 2.2g/t Au for 240,000 ounces of gold[4] and does not include any additional resource growth at these deposits.

Cautionary Statement

The Exploration Targets reported within this announcement are not Mineral Resources. The potential quantity and grade of the Exploration Targets are conceptual in nature and there has been insufficient exploration to determine a Mineral Resource. There is no certainty that additional exploration work will result in the estimation and reporting of Mineral Resources.

Gateway Mining Limited (ASX: GML) ( Gateway or Company ) is pleased to advise that, following a detailed review of historical exploration and drilling data, it has developed an initial Exploration Target for the Achilles Prospect at its 100%-owned Gidgee Gold Project , Western Australia which will be tested as part of a major new drilling program that commenced this week.

The reporting of an Exploration Target is in addition to the recently reported Maiden Inferred Resource for the Whistler and Montague Gold Deposits of 3.4Mt @ 2.2g/t Au for 240,000 ounces of contained gold , which was announced to the market earlier today[2] . Together with the significant exploration upside at Whistler and Montague, the new Exploration Target highlights the substantial growth potential of the Gidgee Project.

Achilles Exploration Target

Gateway has now completed a full evaluation and interpretation of the Achilles Exploration Target, which is located on the highly prospective margin of the Montague Granodiorite (Figure 1). The generation of this Exploration Target has involved the validation of all historical drilling data and then applying new structural and stratigraphic concepts built on the recent work at both the Whistler and Montague Gold Deposits.

This work by the Company has highlighted the potential of the Achilles Exploration Target to advance rapidly to a JORC 2012 compliant Mineral Resource with additional drilling.

The Achilles Exploration Target incorporates the previously separate NE Caledonian, Rosie North, S-Bend, AF1 Lode and Rosie Prospects. In total, the target extends for a strike length of approximately 1.5km and now comprises an estimated Exploration Target of 1.2 Mt to 3.4 Mt at 2.3g/t to 3.4g/t for 88,000oz and 370,000oz of contained gold.

KEY POINTS – Assumptions and Methodologies

• All drilling results utilised to derive the Achilles Exploration Target are historical in nature and were completed both by Gateway (pre-2018) and previous owners of the Gidgee Gold Project. Drilling information has been verified where possible in relation to locational accuracy, sampling protocols and analytical quality control procedures. The drilling data comprises a combination of reverse circulation (RC), diamond and rotary air blast (RAB)[1] .

• A total of 55 drill holes have intersected the mineralised shear zones of interest. A complete list of these intercepts are provided in Appendix 1.

• The potential size and contained ounces of gold of the Exploration Target are presented in Table 1 as a range of values, which in the Competent Person’s opinion, represent a reasonable approximation based on the level of available information and estimation methodologies applied.

• The Exploration Target consists of four mineralised structures that have previously been considered distinct and separate. It is now understood that these structures are part of a greater structural domain and are likely to be interlinked by additional structures. The NE Caledonian, Rosie North, S-Bend, AF1 Lode and Rosie Prospects are the component structures that now make up the current Achilles Exploration Target (Figure 2).

• The Rosie North, S-Bend and the AF1 lodes are largely sub-vertical, north-striking shear zones hosted in the mafic volcanic rocks on the immediate margin of the Montague Granodiorite. Where the mineralised structure intersects the granodiorite it is typical that a broader quartz stockwork zone is also developed.

1 See Appendix (3) for JORC Table 1

2

• The NE Caledonian shear zone is relatively flat-lying (30 degrees) and extends from the immediate base of the historical shallow open pit. The mineralisation is typified by quartz veins within a strongly sheared and foliated mafic volcanic rock host sequence. The geometry and style of mineralisation is very similar to that seen at the Montague Gold Deposit which is located 800m to the immediate north.

• The estimation process was based on assessing the potential for mineralisation amenable to shallow mining techniques to a depth of approximately 100m and making an assessment on the potential for higher-grade mineralisation to a depth of 200m below surface.

• In the top 100m, either from surface or from the base of the historical open pits, in-house modeling of the gold mineralisation has been completed where it is partially defined by drilling. This work has not been reported as a Mineral Resource Estimation at this point due to insufficient drill spacing and the inclusion of a component of RAB drilling.

• From 100-200m an assessment was made of high-grade domain characteristics within the existing drilling. Width and grades were adjusted and projected to an arbitrary depth of 200m.

• An average specific gravity of 2.65 was applied to all of the exploration target. This is based on recent information collected from the resource estimation process at Whistler and Montague.

• A range of reported outcomes were based on both depths below surface and grade variation (See Table within Appendix 2 for detailed workings)[2] .

MANAGEMENT COMMENT

Gateway’s Managing Director, Mr Peter Langworthy, said the announcement of an initial Exploration Target for the Achilles Prospect, together with the maiden 240,000oz JORC Mineral Resource for the Whistler and Montague Deposits also announced today, provided further evidence of the substantial long-term growth potential at the Gidgee Gold Project.

“While the maiden Resources announced separately today provides a solid starting base for the Company, we see a huge opportunity to quickly grow this Resource base well beyond its current position,” Mr Langworthy said.

“This growth will come from a combination of the massive scope to immediately expand the Resource base at both Whistler and Montague, while at the same time targeting advanced, high-potential opportunities like the one we have now identified at the Achilles Exploration Target.

“Given the significant amount of drilling already completed over parts of the Achilles Target, we believe we will be able to add ounces in this area relatively quickly while also targeting immediate extensions and new discoveries along strike and down-plunge.

“And this still only represents a small part of the wider Gidgee Project – which remains wide open in terms of its discovery potential across the Montague Granodiorite,” he said.

“We are very pleased that drilling has now resumed as part of our systematic exploration approach to unlocking the potential of this area, and we are looking forward to advancing the Gidgee Project to the next level.”

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 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.	• Historic 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.

Criteria	JORC Code explanation	Commentary
		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 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 drilling rig specifications.
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

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.	• Drill lines were orientated perpendicular to the perceived strike of the mineralized structure. Inclined RC holes (-60 degrees) are perpendicular to the dip of the mineralized structure creating minimal sampling bias. The vertical RC holes are around 20-30 degrees off being perpendicular to the dip in the mineralised structure creating a minimal sampling bias. • 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. 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.
Sample security	• The measures taken to ensure sample security.	• Calico samples are sealed into green/poly weave bags and cable tied. These are then sealed in bulka bags and transported to the laboratory in Perth by company staff or trusted contractors or established freight companies.

				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

			•	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 was paid to mineralisation other than gold. Gateway Mining in joint
