DECEMEBER 2018 QUARTERLY ACTIVITIES AND CASH FLOW REPORT
GIDGEE GOLD PROJECT, W.A. Summary
-
Outstanding results were received subsequent to the end of the quarter from in-fill and extensional Reverse Circulation drilling completed during December 2018 at the Whistler and Montague Gold Deposits, part of Gateway’s 100%-owned Gidgee Gold Project in WA[1] .
-
Drilling at Whistler will now lead to the estimation of a maiden Mineral Resource. Results include (see Appendix 2 for details):
-
GRC0346 21 metres @ 5.30g/t Au from 149 metres
-
GRC0354 15 metres @ 4.51g/t Au from 119 metres
-
GRC0364 8 metres @ 6.04g/t Au from 190 metres
-
GRC0343 6 metres @ 14.5g/t Au from 198 metres
-
GRC0356 26 metres @ 2.61g/t Au from 126 metres
-
GRC0355 18 metres @ 2.85g/t Au from 114 metres
-
GRC0345 32 metres @ 1.21g/t Au from 125 metres
-
GRC0344 8 metres @ 1.10g/t Au from 103 metres
-
GRC0353 11 metres @ 1.78g/t Au from 100 metres
-
-
The results have confirmed the quality of the mineralisation immediately below the historical Whistler Open Pit and provide strong indications of high-grade extensions at depth.
-
The next phase of work at Whistler will include the estimation of a Mineral Resource, with a particular focus on immediate extensions from the base of the existing open pit, continued evaluation of the deeper potential through a program of diamond drilling, and the commencement of preliminary metallurgical and geotechnical test work.
-
In addition to the main mineralised zone at Whistler, a series of new targets have been identified in both the hanging wall and footwall that will require additional evaluation.
-
At the Montague Gold Deposit a series of high-grade intersections from drilling completed in late 2018 has confirmed the presence of a significant high-grade gold mineralised structure immediately down-dip of the historical Montague open pit. Montague is located 1.2km south of the recently announced results from the Whistler Deposit.
-
Results from this program of Reverse Circulation drilling (RC) include (see Appendix 2 for details):
-
GRC357 5 metres @ 11.5g/t Au from 104 metres
-
GRC358 2 metres @ 5.80g/t Au from 75 metres GRC342 9 metres @ 4.24g/t Au from 89 metres GRC330* 7 metres @ 3.91g/t Au from 70 metres (within 15 metres @ 2.10g/t Au) and; 4 metres @ 24.1g/t Au from 239 metres (“Gordon’s Lode”)
-
GRC325* 5 metres @ 4.47g/t Au from 70 metres GRC360 3 metres @ 2.16g/t Au from 64 metres GRC361 7 metres @ 1.56g/t Au from 78 metres

-
The mineralised shear zone extends from the immediate base of the historical Montague Open Pit and demonstrates clear potential for significant extensions as it remains open down-dip and along strike.
-
All drilling intersections to date are in shallow positions, within 100m of the surface.
-
The parallel, deeper “Gordon’s Lode” structure remains open in all directions and highlights the potential of the wider Montague gold system to host multiple, significant zones of very high-grade gold mineralisation.
-
Significant potential also exists to expand the zones of remnant gold mineralisation in the base of the shallow historical pit. These zones have the potential to be captured in any future cut-back of the open pit.
-
A program of step-out RC drilling has been planned to test the extensions of the mineralisation. Subject to permitting, this program will commence before the end of the current quarter.
Gateway Mining Limited (ASX: GML) ( Gateway or Company ) is pleased to report that outstanding new drilling results have been returned from the most recent program of in-fill and extensional drilling at the Whistler and Montague Gold Deposits, within its 100%-owned Gidgee Gold Project in Western Australia (Figure 1).
This drilling was designed to provide sufficient information beneath the historical open pits to either undertake the estimation of a maiden Mineral Resources, and/or to evaluate the potential for high-grade extensions at depth. The program has been successful in achieving both objectives.

- The drilling has confirmed the presence and distribution of significant zones of thick, high-quality, gold mineralisation that remains open both at depth and along strike. The recent results include (Figures 2 and 3):

GRC0354 15 metres @ 4.51g/t Au from 119 metres

GRC0364 8 metres @ 6.04g/t Au from 190 metres GRC0343 6 metres @ 14.5g/t Au from 198 metres GRC0356 26 metres @ 2.61g/t Au from 126 metres GRC0355 18 metres @ 2.85g/t Au from 114 metres GRC0345 32 metres @ 1.21g/t Au from 125 metres GRC0344 8 metres @ 1.10g/t Au from 103 metres GRC0353 11 metres @ 1.78g/t Au from 100 metres
-
While the mineralisation remains open and is yet to be constrained, the Company has decided to undertake an interim maiden Mineral Resource estimation with a particular focus on understanding the potential to undertake a cut-back on the existing open pit. Additional drilling is expected to expand the resource at depth and along strike.
-
In parallel with the resource estimation process, preliminary programs of metallurgy and geotechnical evaluation will be instigated. The resource is scheduled for completion by the end of the current quarter and drilling will also commence during this time.
-
A program of diamond drilling is currently being designed to continue testing the down-dip extensions to the highgrade mineralisation. This will include a series of new holes and also the completion of drilling four diamond tails to pre-collars completed in the recent work (Figure 2). The diamond tails are required due to the depth limitations of RC drilling due to water inflows.
-
The new information has also provided important information on the structural parameters that control the plunge of the mineralisation and the positioning of the off-setting fault through the southern end of the deposit. This understanding allows for future drill targeting to be further optimized.
-
A series of parallel gold mineralised structures have been identified in the hanging wall and footwall of the main mineralised zone at Whistler. Additional work is required to establish the ultimate significance of these positions, but they demonstrate the greater endowed potential of the Whistler mineralised system.

-
This recently completed program of Reverse Circulation (RC) drilling continues to confirm the presence of a significant high-grade gold mineralised structure immediately down-dip of the Montague historical open pit. The recent results include (Figures 4 and 5):
-
GRC357 5 metres @ 11.5g/t Au from 104 metres
-
GRC358 2 metres @ 5.80g/t Au from 75 metres
-
GRC342 9 metres @ 4.24g/t Au from 89 metres
-
GRC330* 7 metres @ 3.91g/t Au from 70 metres (within 15 metres @ 2.10g/t Au) and; 4 metres @ 24.1g/t Au from 239 metres (“Gordon’s Lode”)
-
GRC325* 5 metres @ 4.47g/t Au from 70 metres
-
GRC360 3 metres @ 2.16g/t Au from 64 metres
-
GRC361 7 metres @ 1.56g/t Au from 78 metres
(* Previously reported results – see ASX announcement dated 10 July 2018)
-
The mineralisation remains open down-dip and is largely untested along strike. Additional drilling is considered likely to substantially expand the mineralised zone.
-
°
-
• The mafic-hosted shear zone has a moderate dip (30–45 ), resulting in a significant amount of the mineralisation being located in shallow positions (<100m to date). In addition, the presence of the parallel, high-grade Gordon’s Lode ( 4m @ 24.1g/t Au ) at depth, indicates that the potential for multiple structures is excellent.
-
Mining of the historical Montague Open pit was limited to shallow, oxide mineralisation. Extensions of the mineralisation into primary fresh rock in the base of the pit have not been systematically tested (Figure 3). On this basis, Gateway believes that significant potential exists to expand these zones of remnant gold mineralisation with additional drilling for inclusion in any future cut-back of the open pit.
4
- Given that the mineralisation is totally unconstrained and appears to be strengthening at depth, a decision has been taken to complete an additional round of drilling to expand the zone prior to committing to any Mineral Resource estimation work. This will also include a diamond tail on an existing RC pre-collar to further test Gordon’s Lode at depth.

- A second phase of preliminary metallurgical test work comprising accelerated cyanide partial leach assays (2kg Leachwell Assays: see Appendix 2 for details) has also now been completed for the mineralised intersections at both Whistler and Montague. The results provide clear evidence that the gold at both deposits is free milling in nature.
REGIONAL PROJECTS
There has been not been any exploration activities on the Company’s regional exploration projects during the reporting period.
TENEMENTS
There have been no material changes to the Company’s tenement holdings during the reporting period (see Appendix 1).
CAPITAL RAISING
During the reporting period, on 22 October 2018 the Company announced that it had successfully completed a capital raising of A$1.5 million (before costs) ( Placement) to institutional, professional and sophisticated investors to underpin the upcoming drilling program at the Gidgee Gold Project.
The Placement, which comprised the issue of 100,000,003 shares at an issue price of $0.015 per share, was strongly supported by existing and new investors including, subject to shareholder approval, by the Company’s directors.
The proceeds of the Placement underpinned recent exploration programs at the Gidgee Project as part of the Company’s recently announced exploration and resource development strategy in relation to highly prospective gold prospects outlined on the margin of the Montague Granodiorite.

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. |
• RC drilling - 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. 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 accountfor a recognized coarsegold 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.). |
• 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. 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 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. 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: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. |

Core (or costean, channel, etc.) photography. • The total length and percentage of the relevant intersections logged. |
• Reverse circulation 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. • Data on rock type, deformation, colour, structure, alteration, veining, mineralisation and oxidation state were recorded. • Logging is both qualitative and quantitative or semi quantitative in nature. 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. 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. |
• Samples were split from dry, 1m bulk sample via a cone splitter directly from the cyclone. • The QC procedure adopted through the process includes: oWeighing both calicos and reject sample to determine sample recovery and check for sampling bias. oField duplicates were collected at a rate of 1:25, these were collected during RC drilling at the same time as the primary sample. oOREAS certified material (CRM) was inserted at a rate of 1:25, the grade ranges of the CRM’s were selected based on grade populations. • 2-3kgs of sample was submitted to the laboratory. • Samples oven dried at 10gdegC then pulverized in LM5 mills to 85% passing 75micron. • All samples were analysed for Au using the Au-AA26 technique which is a 50g lead collection fire assay. • Quality control for maximising representivity of samples included sample weights, insertion of field duplicates and laboratory duplicates. |

• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
• Drill samples were submitted to ALS (Perth). All samples were analysed by a 50g fire assay (AAS finish) which is a total assay. • Ore zones were also submitted for accelerated cyanide leachwell test work. This is involves a 2000g leach with AAS finish. • Field duplicates were collected at a rate of 1:25 with CRM’s inserted at a rate of 1:25 also. The grade ranges of the CRM’s were selected based on grade populations. 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. 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. |
• Drilling results are cross checked by company geologists and consulting geologists (OMNI GeoX Pty Ltd.) • Data is recorded digitally at the project within standard industry software, assay results received digitally also. • All data is stored within a suitable database. 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. 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. |
• Drill hole location is initially recorded with a handheld Garmin GPS (+/- 3m) and will eventually be recorded by Digital GPs (+/-1cm). A Reflex EZ North Seeking Gyro is used to record the deviation of the drill holes (+/- 1deg) 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. 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. |
• Refer to tables within text for data spacing. • Holes drilled within this program in combination with the historical holes and their related samples are deemed to be appropriate for resource estimation. Historical Drilling: All information referred in this report not collected in this currentprogram 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. |
• Drill lines were orientated perpendicular to the perceived strike of the mineralized structure. Drilling at Whistler intercepts mineralisation at an oblique angle to the dip (~15deg off). The orientation of drilling is suitable for the mineralisation style and orientation of mineralisation. 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. 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. 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. 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. No information. |
| Audits or reviews |
• The results of any audits or reviews of sampling techniques and data. |
• Drilling results are cross checked by company geologists and consulting geologists (OMNI GeoX Pty Ltd.) |
