ASX Announcement: 23 August 2018
STRONG AIRCORE DRILLING RESULTS OUTLINE 4 KILOMETRE LONG PROSPECTIVE CORRIDOR AT GIDGEE
Eight new high-priority targets identified along strike from the advanced Whistler, Montague and Caledonian prospects
HIGHLIGHTS
-
Multiple high-priority targets confirmed by a recently completed systematic Aircore (“AC”) drilling program designed to test the highly prospective margin of the Montague Granodiorite at the Gidgee Gold Project in WA. New and historical drilling results include[1] :
-
GWAC0125 16 metres @ 1.73g/t Au from 20 metres
-
GWAC0106 7 metres @ 1.34g/t Au from 13 metres
-
GWAC0001 14 metres @ 1.61g/t Au from 20 metres
-
MOA143R* 23 metres @ 2.03g/t Au from 33 metres
-
GWAC0093 4 metres @ 1.08g/t Au from 10 metres
-
GWAC0151 4 metres @ 1.01g/t Au from 40 metres
-
89MRP48* 7 metres @ 3.10g/t Au from 34 metres
-
GWAC0015 26 metres @ 0.56g/t Au from 10 metres
-
(* Historical intercepts)
-
These highly significant results have been returned from within multiple, extensive anomalies defined by a >0.1g/t Au (100ppb Au) contour and which are interpreted to extend for up to 1km.
-
Many of the intersections were returned from the “bottom-of-hole” meaning the mineralisation remains to be fully tested at depth.
-
The drilling has successfully located the key contact between the granodiorite and the mafic volcanic rocks and has identified areas of structural complexity that may be the focus of substantial gold mineralisation.
-
The next stage of detailed follow-up drilling is currently being planned with relevant statutory approvals in progress.
Gateway Mining Limited (ASX: GML) ( Gateway or Company ) is pleased to advise that it has further expanded the scale and potential of its 100%-owned Gidgee Gold Project in WA (Figure 1) after identifying a series of extensive and highly prospective new target areas from a recent systematic Aircore drilling program.
1 All holes reported as uncut, down-hole widths. Sample intervals range from 1 to 4 metres.
The new targets lie directly along strike from and between the three advanced prospects drilled to date (Whistler, Montague and Caledonian) and define a 4km long prospective corridor along the margin of the Montague Granodiorite, the major structure controlling gold mineralisation in the area.

KEY POINTS
-
This drilling continues to confirm the potential for this major structural corridor on the margin of the Montague Granodiorite to host multiple, significant zones of mineralisation. These zones now present as high-priority targets for the next phase of drilling.
-
Key results reported from this regional, systematic program of Aircore drilling include (see Tables 1 and Appendix 1 for more detail):
-
GWAC0125 16 metres @ 1.73g/t Au from 20 metres
-
GWAC0106 7 metres @ 1.34g/t Au from 13 metres
-
GWAC0001 14 metres @ 1.61g/t Au from 20 metres
-
MOA143R* 23 metres @ 2.03g/t Au from 33 metres
-
GWAC0093 4 metres @ 1.08g/t Au from 10 metres
-
GWAC0151 4 metres @ 1.01g/t Au from 40 metres
-
89MRP48* 7 metres @ 3.10g/t Au from 34 metres
-
GWAC0015 26 metres @ 0.56g/t Au from 10 metres
-
These reported significant intersections lie within extensive zones of gold anomalism defined by a >0.1g/t Au (100ppb) contour (Figure 2).

-
Eight major target zones that individually extend over a strike length of up to 1km have been identified as priority targets and a number of other areas require additional assessment. Areas of particular interest include:
-
The “Our Jack Prospect” , located ~400m north of the historical Montague Pit, where two major shear zones hosting significant gold mineralisation have been intersected by drilling within a broader, gold anomalous zone (Figures 2 and 3). The mineralisation remains open along strike and down-dip. Key results include:
-
GWAC0125 16 metres @ 1.73g/t Au from 20 metres
-
oGWAC0106 7 metres @ 1.34g/t Au from 13 metresoMOA143R* 23 metres @ 2.03g/t Au from 34 metresoGWAC0107 20 metres @ 0.13g/t Au from 28 metres
-
Additional targets at this prospect include the granodiorite-mafic contact and an interpreted position beneath significant gold anomalism reported in the transported cover ( GWAC0123: 12m @ 0.23g/t Au from surface).

Figure (3): Our Jack Prospect – Interpreted Cross-Section 6,967,425N
- The drilling to the north and south of the Montague Pit indicates strong anomalism along the targeted trend for up to 1km. There is a strong possibility that this trend links up with the Our Jack Prospect.

- The “C2 Target”[2] (Figure 4) has been identified over a strike length of ~500m and remains open to the north and south. Drill testing is currently shallow and follow-up drilling is now required to test for mineralisation at depth. As has been seen elsewhere across the Gidgee Project in recent drilling (Whistler and Montague), there is a considerable high-grade gold component to the mineralisation in this area.
The structure that links the Caledonian and North East pits has been consistently intersected in the recent Aircore drilling over a strike length of approximately 400m. It is worth noting that most of the aircore drilling finished in highly anomalous mineralisation in the bottom of the holes. In addition, the down-dip extension of the mineralisation projecting out of the base of the North East Pit remains untested at depth.
The highly prospective contact between the Montague Granodiorite and the mafic volcanic rocks remains to be systematically tested in this area.

-
In addition to the targets generated by this recent program of Aircore drilling, ongoing assessment and validation of the historical drilling datasets has identified a strong zone of mineralisation at the “S-Bend Prospect” (Figure 2). While the controls on the mineralisation are still to be established, and additional drilling will be required, it is clear that a potential zone of predominantly high-grade oxide gold mineralisation is present. Historical drilling results from S-Bend include (see Tables 1 and Appendix 1 for more detail):
-
GRB1812 5 metres @ 3.33g/t Au from 35 metres

Following the release of the highly significant results from the Whistler and Montague Prospects. These Aircore drill results represent the final stage of the initial drilling program undertaken by Gateway at the Gidgee Project.)
The results provide the Company with a growing level of confidence that the mineralised system at the Gidgee Project has the potential to develop into a large-scale gold system with a strong high-grade component.
The maiden Aircore drilling program has provided a systematic test of the highly prospective mineralised margin of the Montague Granodiorite over a strike length of approximately 5km from Whistler to Caledonian. The results have highlighted a series of highly anomalous targets over an extensive strike length that require additional drill testing.
Planning and permitting is currently underway for the next phase of evaluation drilling at Whistler, Montague, the C2 Target (Caledonian) and now the Our Jack Prospect. Subject to permitting, programs of drilling will recommence in October 2018.
MANAGEMENT COMMENT
Gateway’s Managing Director, Peter Langworthy, said the recently completed Aircore drilling, combined with a review of historical drilling, had allowed the Company to form a much clearer picture of the emerging potential along the wide, 4km long corridor extending from Caledonian and the adjacent “S-bend” oxide prospect in the south to Whistler in the north.
“We now have the next generation of targets at Gidgee with consistent results demonstrating the potential size of the mineralised corridor along the margin of the Montague Granodiorite,” he said.
“Our systematic approach to exploration is paying dividends, generating an impressive pipeline of exploration opportunities ranging from advanced key target areas such as Whistler and Montague that require immediate detailed follow-up, to earlier stage greenfields targets where the potential is wide open.
“We are particularly excited by the early-stage results from the Our Jack and C2 prospects, where the mineralisation encountered in Aircore drilling is shallow, excellent grade and totally unconstrained at this point in time.
“We are currently planning and obtaining permits for the next phase of drilling, which is scheduled to commence at Whistler and Montague in October. This will be followed by a first-pass assessment of some of these exciting new targets.
“Standing back and looking at the wider opportunity at Gidgee, we still have the prospective southern 5km of the western contact to work up and target, and we are increasingly seeing the opportunity on the eastern margin of the granodiorite. This position is basically untested for 8km!”

APPENDIX (2): 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. |
• 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. • DIAMOND Drilling– Core was drilled by DrillWest. Gateway staff collected the core from the rig and took the core back to the Bibra Core yard where the core was cleaned, reassembled and marked up with metre marks for logging by Gateway geologists. The geologist marked up the core for sampling and the HQ and NQ core was half cut in half using a corewise automatic core saw. Sample lengths were dominantly 1m in length, but where geological contacts were present, the core was sampled to this contact creating a sample less or greater than 1 metre. Minimum sample length is 0.2m and maximum sample length is 1.2m. Duplicates were taken by taking a separate pulp in the preparation stage at the lab at a 1:50 ratio Historical Drilling: |

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. |

| 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 current program 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 mineralized structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
• Drill lines are 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 minerlisation. 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. |
