ASX Announcement: 8 October 2018
ADDITIONAL HIGH-GRADE POTENTIAL IDENTIFIED AT GIDGEE WITHIN NEW ~1.6km LONG ROSIE-AIRPORT TREND
Historical drilling results include exceptional grades, providing another walk-up drilling target
HIGHLIGHTS
-
A strongly mineralised gold trend extending over a ~1.6km strike length has been confirmed at the RosieAirport Prospect, within Gateway’s 100%-owned Gidgee Gold Project.
-
Ongoing assessment and validation of the historical geological databases have identified this zone as a major structural corridor that includes both discrete contact mineralisation between the mafic volcanic rocks and granodiorite, and extensive stockwork mineralised zones within the granodiorite.
-
While additional work is required to fully understand the controls on the high-grade mineralisation within the broader system, key historical drilling results include (see Appendix 1 for details):
-
Contact Zone[1]
-
6 metres @ 8.02g/t Au from 15m
-
2 metres @ 12.8g/t Au from 82m
-

-
▪ 120 metres @ 0.42g/t Au from 80m to end of hole ▪ 47 metres @ 0.70g/t Au from 76m
-
In addition to the main Rosie-Airport Prospect, a zone of supergene gold mineralisation comprising a high-grade core within a broader envelope of lower grade mineralisation has been identified at the Rosie South Prospect. The bedrock controls within the underlying granodiorite are yet to be determined and the strike extensions have not been effectively tested. Historical results include:
• Rosie South – Supergene[3]
-
20m @ 15.6g/t Au from 25m
-
17m @ 14.7g/t Au from 30m

Gateway Mining Limited (ASX: GML) ( Gateway or Company ) is pleased to advise that it has identified another outstanding exploration target at its 100%-owned Gidgee Gold Project in WA (Figure 1) through its systematic program of data validation, interpretation and targeting of the historical technical datasets available for the project.
This work has highlighted the potential of the ~1.6km long Rosie-Airport gold trend to host significant zones of high-grade mineralisation within a broader mineralised envelope. It has also provided an important insight into the controls of large-scale zones of stockwork related gold mineralisation hosted within the granodiorite.
The identification of the new area follows the recently announced 10km long parallel gold trend along the Eastern Margin of the Montague Granodiorite and the 4km long prospective corridor identified through the Company’s maiden drilling program, which encompasses the advanced Whistler, Montague and Caledonian prospects.

KEY POINTS
Rosie-Airport Gold Trend
The Rosie-Airport trend, which hosts the historical Rosie open pit mine, extends over a strike length of approximately 1.6km immediately south of the previously mined NE Pit (Figure 2). The trend covers a large-scale mineralised shear zone on the contact between the mafic volcanic rocks and the Montague granodiorite. Key points include (Figure 3 and 4):
-
Shallow, high-grade gold mineralisation on the contact between the mafic volcanic rocks and the granodiorite remains largely untested. Drilling is typically shallow and completed only on wide-spaced traverses over the ~1.6km strike. Historical drilling results include (see Appendix 1 and 2):
-
6 metres @ 8.02g/t Au from 15m
-
2 metres @ 12.8g/t Au from 82m
-
8 metres @ 6.97g/t Au from 25m
-
10 metres @ 9.96g/t Au from 15m
-
15 metres @ 1.29g/t Au from 25m
-
2 metres @ 10.9g/t Au from 45m
-
▪ 10 metres @ 3.49g/t Au from 30m
-
15 metres @ 1.16g/t Au from 20m
-
▪ 12 metres @ 3.53g/t Au from 45m
2
-
Additional to the contact mineralisation, a broad zone of stockwork gold mineralisation has been defined within the adjacent granodiorite footwall. This mineralisation is interpreted to represent a vector into a potential large zone of higher grade gold. This interpretation requires validation by drilling. Historical drilling results include (see Appendix 1 and 2):
-
147 metres @ 0.42g/t Au from 21m to end-of-hole
-
▪ 120 metres @ 0.42g/t Au from 80m to end-of-hole ▪ 47 metres @ 0.70g/t Au from 76m
Rosie South – Supergene
The Rosie South supergene gold target is located in a position within the granodiorite (Figure 2). Shallow drilling has intersected a core of thick, high-grade gold mineralisation within a broader envelope of lower grade mineralisation over a strike length of approximately 100m. The mineralised trend remains open to the north and the south and the bedrock source of the mineralisation remains to be located.
Historical drilling results include (see Appendix 1 and 2):
-
20m @ 15.6g/t Au from 25m
-
17m @ 14.7g/t Au from 30m
-
15m @ 5.08g/t Au from 35m
-
25m @ 9.06g/t Au from 25m
-
5m @ 8.94g/t Au from 41m
-
15m @ 2.05g/t Au from 20m
-
11m @ 2.20g/t Au from 31m
-
▪ 17m @ 1.24g/t Au from 25m

NEXT STEPS
As previously reported (see ASX announcement dated 18[th] September, 2018), Gateway will commence new exploration programs in October that will initially focus on resource evaluation and resource expansion activities at the Whistler Prospect, followed by a similar evaluation and expansion program at the Montague Prospect. This will position the company to estimate a maiden gold Resource for the Gidgee Project.
This recently identified and validated gold trend at Rosie-Airport, combined with the regionally significant Eastern Contact trend (see ASX Announcement dated 25[th] September 2018), provides a strong pipeline of new targets for future testing. Work to be undertaken will include geological mapping, geochemical sampling, and programs of aircore drilling with follow-up RC drilling as required.
MANAGEMENT COMMENT
Gateway’s Managing Director, Peter Langworthy, said the Company’s systematic approach to reviewing the historical data for the Gidgee Project as part of its ongoing exploration targeting strategy was continuing to yield exciting results.
“Each time we interrogate the historical database, we come up with significant new information – and new, highquality drill targets,” he said. “This shows the substantial and largely untapped exploration potential within our broader ground position at Gidgee.
“Our view is that exploration datasets are a massive asset of resource companies with the potential to host hidden new discoveries. We have been diligently working through 40 years of historical exploration data and, through a disciplined process of validation and evaluation, we are unearthing a series of new high-quality exploration opportunities”.
“While our immediate focus will be to define a maiden Resource position for the project at our high-priority Whistler and Montague Targets, we will also continue pursue the broader exploration potential within our tenements in a measured and systematic way. We are increasingly of the view that the large-scale opportunities we have identified form part of what we believe to be an emerging gold camp.”

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: |

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 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. |
