ASX Announcement: 3 October 2019
MAIDEN 240,000oz RESOURCE SETS STRONG FOUNDATION FOR NEXT PHASE OF GROWTH AT GIDGEE GOLD PROJECT, WA
Outstanding growth potential to be tested by new drilling program, with maiden Resources open in all directions and covering only a small portion of an 18km long prospective contact
HIGHLIGHTS
-
Maiden JORC 2012 Mineral Resource estimate completed for the cornerstone Whistler and Montague Gold Deposits at Gateway’s 100%-owned Gidgee Gold Project, WA:
-
Inferred Resource of 3,425,000 tonnes @ 2.2g/t for 240,000 ounces of contained gold.
-
The Whistler Resource remains open in all directions, with immediate strong potential to extend the mineralisation along strike to the north and south, down-plunge and in a series of separate flat-lying structures discovered recently.
-
The Montague Resource also remains open in all directions and has demonstrated potential for multiple parallel structures at depth as well as expansion of the granite stockwork mineralisation.
-
The maiden Whistler and Montague Resources represent only a minor portion of the prospective contact of the Montague Granodiorite, which extends for at least 18 strike kilometres.
-
To advance the resource expansion and exploration push, a major new drilling program of ~16,000m of Reverse Circulation and air-core drilling has commenced this week. Drilling will target:
-
The immediate next stage of resource expansion at both the Whistler and Montague Gold Deposits;
-
Conversion of a newly-defined Exploration Target for the Achilles Target, which will be announced immediately after this announcement, into a JORC 2012 compliant Mineral Resource; and
-
A series of positions along the margin of the Montague Granodiorite that have been targeted using the recently acquired detailed gravity dataset.
Gateway Mining Limited (ASX: GML) ( Gateway or Company ) is pleased to report a maiden JORC 2012 Inferred Mineral Resource estimate (MRE) for the Company’s 100%-owned Gidgee Gold Project , Western Australia (Figure 1). This initial Mineral Resource position represents the first step in what is expected to be an ongoing process of resource growth and upgrade, over the short to medium term.
The reported Mineral Resources, comprising a total Inferred Resource of 3.425 million tonnes grading 2.2g/t Au 240,000 ounces of contained gold , relate to the Whistler Gold Deposit and Montague Gold Deposit , which are both located on the prospective margin of the Montague Granodiorite. The two Resources are located approximately 800m apart (see Figure 1). The Montague Resource has a component of quartz-stockwork gold mineralisation in the base of the historical open pit which is now referred to as the Boulder Gold Deposit.
Gateway Mining Managing Director, Mr Peter Langworthy, said the completion of a maiden Resource for these two key deposits represented an important first step in the Company’s strategy to develop a new large-scale gold project at Gidgee.
“We are pleased to publish our first JORC Mineral Resource statement for the Gidgee Project, which sets a strong initial foundation for us to unlock the broader potential of this exciting and highly prospective emerging gold project,” he said.
“We have already embarked on a major new drilling campaign following our recent highly successful raising designed to expand and upgrade both Resources, which remain open in all directions. The new drilling program will also focus on the exciting new Achilles Target, where we will today publish an Exploration Target, and other exciting prospects identified in recent months along the highly prospective Montague Granodiorite.
“This is an exciting time for Gateway as we begin to crystallise the value of the Gidgee Project and fast-track our broader exploration efforts to unlock new discoveries and rapidly build our Mineral Resource base.”

RESOURCE EXPANSION AND EXPLORATION – Whistler and Montague Gold Deposits
To advance the resource expansion and exploration push, a major new drilling program of ~16,000m of Reverse Circulation and air-core drilling has now commenced at the Gidgee Gold Project. A significant component of this program will be focused on expanding the Whistler and Montague Gold Deposits.
Whistler Gold Deposit
An opportunity exists to aggressively target a significant expansion of the Whistler Gold Deposit beyond the reported Mineral Resource. The gold deposit remains open in all directions, with immediate strong potential to extend the mineralisation along strike to the north and south, down-plunge and in a series of separate flat-lying structures that have recently been discovered.
4
The greater Whistler mineralised trend has been defined by shallow drilling over a strike length of approximately 1.25km.
Montague Gold Deposit
The Montague Gold Deposit remains open in all directions and is potentially part of a mineralised system consisting of multiple flat-lying shear zones with the mafic volcanic rock package and quartz-stockwork zones on the margin of the granodiorite. The prospective contact zone remains largely untested to the north and south for approximately 2.2km.
SUMMARY OF GIDGEE GOLD PROJECT MINERAL RESOURCE ESTIMATE
Whistler
Geology, Geological Interpretation and Mineralisation
The Whistler Gold Deposit, within Gateway Mining Ltd’s Gidgee Project is located approximately 630km NE of Perth and 70km north of Sandstone within mining tenement M57/217.
The geology at Whistler comprises of a basalt-granodiorite contact with granodiorite to the west and basalt and minor gabbro dykes to the east, with the mafic rocks being saprock to fresh at the water level. The contact dips steeply west and strikes 345°, and is relatively undeformed at both ends of the pit. The basalt on the east wall is intruded by two gabbro dykes oriented 55-90°→095°. The granodiorite is intruded by a swarm of 1-15m thick biotite-lamprophyre dykes oriented 85-90°→110-115°.
The ore zone at Whistler consists of an en echelon array of NNE-striking veins that cut across a N-S striking, 70° west-dipping foliation which is hosted predominantly in the granodiorite unit.
Drill hole Database
The drill hole database provided for the Whistler deposit contains data for 341 individual drill holes. A restriction has been applied to the database for the estimation of Whistler between the MGA northings of 6,967,900mN and 6,968,400mN and MGS eastings of 751,350mE and 752,000mE. Auger, air core (AC), rotary air blast (RAB) and water bore drill holes have been excluded.
In total, 45 diamond drill holes (DDH) for a total of 7,031.45m and 72 Reverse Circulation (RC) drill-holes for a total of 15,568m have been utilised in the Mineral Resource estimate.
The surface drill hole sections have been predominately drilled on an azimuth of ~270 degrees, with a general dip of -60 degrees. Approximately four historic drill holes were drilled ~090 degrees with a general dip of -60 degrees.
Sampling
Drilling at Whistler was historically drilled by CRA Exploration (1987-1989) and positioned on a grid with a nominal spacing of 20x25m. Verification of data was conducted from open file annual reports. Diamond core was generally half cut sampled over 1m downhole intervals, with infrequent sampling of up to 2m. RC samples were riffle split on 1m downhole intervals. All CRA samples were analysed via 50g fire assay method, a proportion of samples were also analysed for multi-elements.
Gateway RC sampling: 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. A second 2kg-3kg sample was collected at the same time as the original sample. This sample was stored on site and 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.
Gateway Diamond sampling: Core was drilled by DDH1 Drilling Pty Ltd. 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 was 0.2m and the maximum sample length was 1.2m. Duplicates were taken by taking a separate pulp in the preparation stage at the lab at a 1:50 ratio.

Assaying
CRA analysed all drill holes by AAS assay at 1-metre intervals. Where the value exceeded 0.5 g/t Au the sample was re-analysed by 50g fire assay. Where the fire assay exceeded 3 g/t Au or where spotty gold was suspected, the sample was re-analysed by screen fire assay. The protocol for a given sample was that screen fire assays were better than fire assays which were in turn better than AAS assays. For all resource/reserve calculations fire assays and screened fire assays only were used.
Gateway 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 involved 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.
Resource Estimation
(a) Geological Modelling
Geological and mineralisation wireframes have been generated inhouse by creating lithology wireframes and applying a cutoff grade of 0.3 g/t Au.
The geological and weathering wireframes have been generated in LeapFrog Geo implicit software from logged lithology and oxidation records.
(b) Variography
Variography has been completed in Supervisor 8.7 software on a grouped domain basis where enough data is present. Domains with too few composites have borrowed variography.
Variograms have been modelled using the following approach:
-
All variograms are standardised to a sill of one;
-
The nugget effect has been modelled from the true downhole variogram;
-
Variograms have been modelled using two or three-structure nested spherical variograms;
-
The variograms have been evaluated using normal scores transforms rather than traditional variograms. This method produces a clearer image of the ranges of continuity, especially in skewed datasets;
-
All variogram models have been standardised to a sill of one. The nugget and sill values have been back-transformed in Supervisor to traditional variograms using the discrete Gaussian polynomials technique.
(c) Block Model Estimation
Grade estimation of gold g/t has been completed using Ordinary Kriging (OK) into 29 mineralised domains using Maptek Vulcan 11.0.2 software. Grade assignment of gold at 0 g/t has been undertaken in unestimated blocks only.
Top cutting of grade has not been assigned to any of the assays for the Whistler mineral resource estimation. This affects a single Domain and is not considered material to the total inferred resource. The Domain has a noted amount of coarse visible gold and is considered geological distinct from the rest of the resource and as such a decision was made to not to apply a top-cut. Additional drilling will be required in this Domain to confirm the full characteristics of the gold prior to any increase in resource confidence levels.
(d) Block Model Construction
The block model parent block size is 12.5m (X) by 12.5m (Y) by 5m (Z). A sub-block size of 0.5m (X) by 0.5m (Y) by 0.1m (Z) has been used to define the mineralisation edges, with the estimation undertaken at the parent block scale.
- Pass 1 estimations have been undertaken using a minimum of 8 and a maximum of 30 samples into a search ellipse which ranges of 25m (Dir 1) by 25m (Dir 2) by 15m (Dir 3). A sample per drill hole
limit of 4 samples/drill hole has been applied in all domains.
-
Pass 2 estimations have been undertaken using a minimum of 8 and a maximum of 30 samples into a search ellipse which ranges of 50m (Dir 1) by 50m (Dir 2) by 30m (Dir 3). A sample per drill hole limit of 4 samples/drill hole has been applied in all domains.
-
Pass 3 estimations have been undertaken using a minimum of 4 and a maximum of 30 samples into a search ellipse which ranges of 100m (Dir 1) by 100m (Dir 2) by 60m (Dir 3). No sample per drill hole limit has been applied.
The following bulk densities have been applied to the resource estimation model:
| Domain / Lithology | Weathering | Bulk Density Assigned t/m3 |
|---|---|---|
| Waste dumpfill | NA | 1.4 |
| Basalt | Oxide | 1.8 |
| Granodiorite | Oxide | 1.8 |
| Biotite Schist | Oxide | 1.8 |
| Basalt | Fresh | 2.9 |
| Granodiorite | Fresh | 2.7 |
| Biotite Schist | Fresh | 2.8 |
High grade yields have been applied in three domains in order to reduce the smearing of high grades during estimation.
(e) Resource Classification
Classification of the Whistler Mineral Resource estimate has been completed in accordance with the Australasian Code for Reporting of Mineral Resources and Ore Reserves (the JORC Code, as prepared by the Joint Ore Reserve Committee of the AusIMM, AIG and MCA and updated in December 2012).
All classifications and terminologies have been adhered to. All directions and recommendations have been followed, in keeping with the spirit of the code. The categories of Mineral Resource as outlined by the code are as follows;
-
Measured - tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence.
-
Indicated - tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence.
-
Inferred - tonnage, grade, and mineral content can be estimated with a reduced level of confidence.
The resource classification has been applied to the Mineral Resource estimate based on the drilling data spacing, grade and geological continuity, and data integrity. The resource has been classified on the following basis;
-
The Measured Mineral Resource classification has not been applied to the Whistler mineral resource estimate;
-
The Indicated Mineral Resource classification has not been applied to the Whistler mineral resource estimate. Whilst drill spacing is sufficient, the limited documented hardcopy assay data reports and documented geological information reduces the confidence of the resource to lower than Indicated;
-
An Inferred Mineral Resource has been defined by a nominal drill spacing of 25m by 25m, to 25m by 50m.

(f) Mineral Resource Optimised Pitshell
The current in situ, drill-defined resource inventory for the Whistler Deposit has been reported inside an optimized pit-shell at a cut-off of 0.5g/t Au at a gold price of AUD $2,400. The pit-shell has been generated in Whittle by Mining Plus by applying the costs/gold price.

Montague
Geology, Geological Interpretation and Mineralisation
The Montague Gold Deposit, within Gateway Mining Ltd’s Gidgee Project is located approximately 630km NE of Perth and 70km north of Sandstone within mining tenement M57/98.
The historic open cut pit is interpreted to comprise of two domains of mineralisation, separated by a NW-SE striking fault. The western extent of the pit contains WSW dipping mineralisation of the Montague Lode, and the eastern extent containing SSE dipping Boulder mineralisation.
The Montague and Gordon’s Lode is hosted entirely within a shallow westerly dipping biotite schist which displays significant sericite alteration on the hangingwall margin. This unit is hosted within the aphyric basalt unit on the western margin of the granodiorite. The Boulder lode is hosted entirely within the granodiorite unit.
Drill Hole Database
The drill hole database provided for the Montague deposit contains data from 371 individual drill holes. A restriction has been applied to the database for the estimation of Montague between the MGA northings of 6,967,550mN and 6,966,500mN and MGA eastings of 750,500mE and 751,500mE. Auger, air core (AC), rotary air blast (RAB), Grade Control (GC) and water bore drill holes have been excluded.
8
In total, 7 diamond drill holes (DDH) for a total of 1,668.9m and 364 Reverse Circulation (RC) drill-holes for a total of 18,886m have been utilised in the Mineral Resource estimate.
The surface drill hole sections have historically been drilled vertically while the more recent Gateway drilling has been drilled both vertically and with an azimuth of 090 degrees and a dip of -60. The more recent drilling has been targeting the shallow dipping Montague mineralised structure.
Sampling
Historic mining of the Boulder lode is reported recovering 7076.4 tonnes @ 19.9g/t Au from 1906 to 1913 underground “room and pillar stoping in a shallowly dipping main lode” (Clackline Ltd NOI report, mp 15, pg3, 1988). Operations drilling conducted by Herald Resources (1986-88) located south of the Boulder surface workings, contain downhole lengths where assays are missing from the hardcopy reports. It is unclear as to whether the samples were assayed or whether stoping was encountered during drilling. Due to the level of ambiguity with these samples, these drill holes were omitted from this resource estimation process.
From the documented assays, Herald Resources RC and diamond sampling was conducted over 1m intervals.
Gateway RC sampling: 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. A second 2kg-3kg sample was collected at the same time as the original sample. This sample was stored on site and 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.
Gateway Diamond sampling: Core was drilled by DDH1 Drilling Pty Ltd. 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 was 0.2m and the maximum sample length was 1.2m. Duplicates were taken by taking a separate pulp in the preparation stage at the lab at a 1:50 ratio.
Assaying
Herald Resources RC and diamond sampling was conducted over 1m intervals and submitted to Pilbara Laboratories for a 50g fire assay analysis.
Gateway 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 involved 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.
Resource Estimation
(g) Geological Modelling
Geological and mineralisation wireframes have been generated inhouse by creating lithology wireframes and applying a cutoff grade of 0.5 g/t Au.
The geological and weathering wireframes have been generated in LeapFrog Geo implicit software from logged lithology and oxidation records.
(h) Variography
Variography has been completed in Supervisor 8.7 software on a grouped domain basis where enough data is present. Domains with too few composites have borrowed variography.
Variograms have been modelled using the following approach:
-
All variograms are standardised to a sill of one;
-
The nugget effect has been modelled from the true downhole variogram;
-

-
All variogram models have been standardised to a sill of one. The nugget and sill values have been back-transformed in Supervisor to traditional variograms using the discrete Gaussian polynomials technique.
(i) Block Model Estimation
Grade estimation of gold g/t has been completed using Ordinary Kriging (OK) into 21 mineralised domains using Maptek Vulcan 11.0.2 software. Grade assignment of gold at 0 g/t has been undertaken in unestimated blocks only.
Top cutting of grade has not been assigned to any of the assays for the Montague mineral resource estimation. The mafic volcanic hosted domains have a recognised nugget effect however the higher grades are considered to be representative on a geological basis. Additional drilling will be required in the mafic volcanic hosted domains to confirm the full characteristics and distribution of the gold prior to any increase in resource confidence levels.
(j) Block Model Construction
The drill hole data spacing is typically 20m by 20m with areas of extensional drilling at 80m by 80m in the downdip and along-strike extents.
The block model parent block size is 10.0m(X) by 10.0m (Y) by 5.0m (Z). A sub-block size of 2.0m (X) by 2.0m (Y) by 0.5m (Z) has been used to define the mineralisation edges, with the estimation undertaken at the parent block scale.
-
Pass 1 estimations have been undertaken using a minimum of 8 and a maximum of 20 samples into a search ellipse which ranges of 72m (Dir 1) by 30m (Dir 2) by 24m (Dir 3). A sample per drill hole limit of 4 samples/drill hole has been applied in all domains.
-
Pass 2 estimations have been undertaken using a minimum of 8 and a maximum of 20 samples into a search ellipse which ranges of 120m (Dir 1) by 50m (Dir 2) by 40m (Dir 3). A sample per drill hole limit of 4 samples/drill hole has been applied in all domains.
-
Pass 3 estimations have been undertaken using a minimum of 4 and a maximum of 20 samples into a search ellipse which ranges of 120m (Dir 1) by 50m (Dir 2) by 40m (Dir 3). No sample per drill hole limit has been applied.
The following bulk densities have been applied to the resource estimation model:
| Domain / Lithology | Weathering | Bulk Density Assigned t/m3 |
|---|---|---|
| Waste dumpfill | NA | 1.4 |
| Basalt | Oxide | 1.8 |
| Granodiorite | Oxide | 1.8 |
| Biotite Schist | Oxide | 1.8 |
| Basalt | Fresh | 2.9 |
| Granodiorite | Fresh | 2.7 |
| Biotite Schist | Fresh | 2.8 |
High grade yields have been applied in seven domains in order to reduce the smearing of high grades during estimation.
(k) Resource Classification
Classification of the Montague Mineral Resource estimate has been completed in accordance with the Australasian Code for Reporting of Mineral Resources and Ore Reserves (the JORC Code, as prepared
10
by the Joint Ore Reserve Committee of the AusIMM, AIG and MCA and updated in December 2012). All classifications and terminologies have been adhered to. All directions and recommendations have been followed, in keeping with the spirit of the code. The categories of Mineral Resource as outlined by the code are as follows;
-
Measured - tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence.
-
Indicated - tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence.
-
Inferred - tonnage, grade, and mineral content can be estimated with a reduced level of confidence.
The resource classification has been applied to the Mineral Resource estimate based on the drilling data spacing, grade and geological continuity, and data integrity. The resource has been classified on the following basis;
-
The Measured Mineral Resource classification has not been applied to the Montague mineral resource estimate;
-
The Indicated Mineral Resource classification has not been applied to the Montague mineral resource estimate. Whilst drill spacing is sufficient, the limited documented hardcopy assay data reports, historic missing assay data, ‘nugget effect’ associated with the Montague domain and limited documented geological information reduces the confidence of the resource to lower than Indicated;
-
An Inferred Mineral Resource has been defined by a nominal drill spacing of 20m by 20m to 80m by 80m in the down-dip and along strike extents.
(l) Mineral Resource Optimised Pitshell

| 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. |
• DIAMOND Drilling– Core was drilled by DDH 1. Gateway staff collected the core from the rig and took the core back to the 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 • 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 |

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 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. Analysis was carried out by Australian Laboratory Services and Sheen Analytical Services. All holes were cased with 50mm PVC to facilitate downhole geophysical logging. |

| 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. |
• DIAMOND Drilling– Core was drilled by DDH 1. Gateway staff collected the core from the rig and took the core back to the 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 • 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. Thegrade ranges of the CRM’s were selected based |

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. Herald Resources RC and diamond sampling was conducted over 1m intervals and submitted to Pilbara Laboratories for a 50g fire assay analysis. There are several instances with the historic MOA prefixed RC holes where the assay results are missing from the historic hardcopy reports. GML believe that the assay results are missing as opposed to the drill hole not being analysed. These missing intercepts are recorded as -99 in the database and these holes were omitted from the inferred resource model. |

Once coherent coring was established the drill sample recovery was measured routinely by Gateway Geologists. Overall recovery was excellent. • 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.
