Great Boulder acquires option on high-grade gold project at Meekatharra

  • Side Well gold project is located in the richly endowed Meekatharra gold field

  • High grade gold intersections identified in previous drilling

  • Exploration to commence immediately

Great Boulder Resources [ASX: GBR] is pleased to announce the Company has taken an option on a high-grade gold project near Meekatharra in Western Australia.

The Side Well gold project is located next to Meekatharra in Western Australia, adjacent to Westgold Resources’ Murchison Gold Operations and south of the Andy Well gold mine. This richly endowed area has produced nearly four million ounces of gold, with over 2.7 million ounces remaining in current resources[1] .

Previous drilling by Doray Minerals prior to the closure of the nearby Andy Well mine produced a number of high-grade intersections, including:

  • 3m @ 35.5g/t Au from 76m in MNAC0463 (Matilda prospect)

  • 5m @ 6.69g/t Au from 110m in MNAC0454 (Mulga Bill prospect)

  • 14m @ 5.30g/t Au from 86m in SWRC012 (Mulga Bill prospect)

  • 10m @ 3.41g/t Au from 185m in SWRC006 (Mulga Bill prospect).

Much of the Mulga Bill prospect, including the most prospective area, has only been drilled on sections 400m apart - leaving ample room for a significant discovery.

Great Boulder Managing Director Andrew Paterson said the transaction is a significant step forward for the company’s gold exploration strategy.

“Side Well is owned by Zebina Minerals Pty Ltd, a private company owned by Kalgoorlie based prospector Scott Wilson, who originally pegged Andy Well in 1988 and joint ventured it with Doray Minerals. The parallels between Andy Well and Side Well are compelling, in terms of their history as well as their geological setting.

“20 years ago, when WMC were exploring the area they walked away from Andy Well when it was at a similar stage. Ten years later Doray came in and drilled out over 800,000 ounces.

“The history of the Meekatharra field demonstrates this area keeps on giving. Westgold are mining underground at Paddy’s Flat, right in the historic centre of the field. We’re looking forward to getting a rig on the ground as soon as possible.”

About the Side Well gold project

Side Well tenement E51/1905 is a 48-block Exploration Licence covering an area of 131.8km[2] immediately east and northeast of Meekatharra in the Murchison province (Figure 1). The project overlies the Meekatharra – Wydgee greenstone belt and includes upper greenschist-facies rocks of the Luke Creek and Mt Farmer groups. Within the project area these lithologies are folded into a large regional syncline known as the Pollele syncline. Alluvium and lacustrine clays overlie the area.

Exploration History

Regional exploration has been conducted around Side Well by a number of companies over the past 30 years, including Dominion Mining (1992 to 1995), WMC Resources (1996-97), Accent Resources (2009) and Doray Minerals (2010 to 2016). Dominion were the first company to identify significant gold mineralisation in drilling with intersections such as 2m @ 1.67g/t Au and 4m @ 1.4g/t Au in regional RAB traverses[2] .

Dominion Mining and WMC Resources explored the greenstone belt from Andy Well to Side Well during the 1990’s. Dominion discovered significant gold mineralisation at Side Well in 1993, including 26m @ 2.19g/t in hole HAR3015. Shortly afterwards WMC drilled the discovery holes at Andy Well. WMC eventually concluded that the project area did not meet their exploration criteria of a 6Moz discovery, commenting in their 1998 report that “ potential for a near-surface WMC-sized position (e.g. 6Moz) was significantly downgraded. The potential for smaller, perhaps million

ounce, positions remains significant .[3] ” The decision by WMC to leave the area eventually led to the Andy Well project being picked up by Doray Minerals in joint venture with Scott Wilson.

Doray were successful in identifying high-grade gold in drilling at Matilda (3m @ 35.48g/t Au from 76m in hole MNAC0463) and then Mulga Bill where several significant hits in Air-Core (AC) and Reverse Circulation (RC) drilling included 10m @ 3.41g/t Au from 185m in SWRC006, 14m @ 5.30g/t Au from 86m in SWRC012 and 5m @ 6.69g/t Au from 110m in MNAC0454. In January 2013 Doray flew a heli-TEM survey over the project area which provided additional detail for their structural interpretation on the controls to mineralisation. After 2015 Doray’s exploration focus shifted closer to Andy Well as they experienced success at Gnaweeda, while the corporate focus shifted to the ramp-up of operations at Deflector, south of Yalgoo.

Geochemistry

Much of the Side Well area is covered by alluvial material, rendering conventional soil sampling techniques unreliable. This also presents opportunities, and GBR intends to trial a range of analytical techniques to identify underlying mineralisation.

It is a widely accepted principle of Yilgarn exploration that all the significant future discoveries will be made under cover, and this is particularly true in historic mining areas such as Meekatharra.

The only surface sampling recorded over the project area was a 182-point lag sampling program conducted by WMC over the Jones Well area on a 100 x 200m grid in 1997-98. Samples were assayed for Au and As, with the results highlighting a coherent Au-As anomaly at 3ppb Au, with a peak of 14ppb Au. Ten air-core holes were subsequently drilled to test this target with no significant results, indicating that the surface sampling may have been ineffective.

Drilling

GBR has collated a digital database of drilling by Dominion Mining, WMC Resources and Doray Minerals consisting of a total of 535 holes within E51/1905. From the details available, these have been classified as AC (261 holes), RC (16 holes), Diamond (2 holes) and Unknown (256 holes). Many of the unknown hole types are likely to be Rotary Air Blast (RAB).

Hole Type No. Holes Sum of Depth Average Depth
AC 261 24,645m 94m
RC 16 3,870m 242m
DD 2 592m 296m
Unknown 256 12,072m 47m
Total 535 41,179m 77m

Side Well priority targets

Mulga Bill prospect: Gold was first identified at the northern end of Mulga Bill by Dominion, who initially referred to the prospect as Side Well. RAB hole HAR3015 intersected 26m @ 2.19g/t Au from 66m in 1993. Although detailed logging is unavailable, subsequent drilling in the area would suggest that this horizon was at least partially weathered.

Dominion drilled follow-up air-core holes either side of HAR3015, as well as a scissor hole above it, all of which failed to replicate the 26m interval. In their 1993 report Dominion concluded that the result “ appears to be a classic case of RAB smearing quartz in samples of damp puggy mafic clays[4] .”

Later air-core drilling by Doray Minerals 500m south of this hole hit began to identify zones of supergene mineralisation within a broad, north-south corridor. As their exploration continued they tested some sections with a series of RC holes and two diamond tails, with highlights including 14m @ 5.30g/t Au in SWRC012 and 10m @ 3.41g/t Au in SWRC006. By this stage mineralisation had been defined over a strike distance of 3km within a corridor 750m wide. The corridor is defined by supergene gold dispersion within the weathered horizon, with an anomalous copper footprint providing a broader dispersion halo in the same horizon to highlight the overall trend.

FIGURE 3: MULGA BILL HAS SIGNIFICANT MINERALISATION OVER 3KM OF STRIKE, OPEN TO THE SOUTH. THE BETTER SECTIONS ARE DRILLED 400M APART. EARLY REGIONAL DRILLING (4[TH] LINE FROM THE BOTTOM) WAS SHALLOW AND INEFFECTIVE.

Mulga Bill is located in the centre of the Pollele syncline, within felsic to intermediate volcanics and volcaniclastics of the Yaloginda Formation. Previous explorers have hypothesised the position of gold mineralisation at Mulga Bill is influenced by the nearby Gabanintha shear, and Doray interpreted a mineralised felsic to intermediate intrusion which may also be a key influence to mineralisation. Although the drilling is currently sparse, the distribution of significant gold values suggests a possible north-northeast trend to the higher-grade zones, however this hypothesis requires testing with infill drilling.

Analysis of Doray’s 2013 HeliTEM data will enable mapping of a zone of deeper weathering along the mineralised shears.

The better intersections drilled by Doray are within the southern half of the Mulga Bill area. This section was drilled on sections 400m apart, meaning the entire southern 1,600m of Mulga Bill has only been tested by five fences of drilling. Infilling this area and extending the high-grade mineralisation zones will be a priority for GBR.

FIGURE 4: MULGA BILL SECTION 7060200N (ADAPTED FROM DORAY MINERALS 2015 REPORT).

Matilda prospect: Doray’s air-core intersection of 3m @ 35.48g/t Au in hole MNAC0463 at Matilda sits on the west side of the project, on the eastern side of the Paddy’s Flat belt above a discontinuous linear magnetic feature caused by banded iron formation (BIF) and cherts of the Yaloginda Formation. Petrographic analysis of RC chips from hole SWRC003 at Matilda identified a carbonate-chlorite-sericite-altered porphyry, possibly andesite, however SWRC003 failed to intersect significant grade at depth beneath MNAC0463.

The high-grade intersection in MNAC0463 was logged as moderately weathered, fine-grained quartz-feldspar-mica schist. Holes either side were simply logged as upper to lower saprolite, suggesting positive identification of the host lithology would be unreliable, and there may be a supergene component to the gold interval. Aside from the two holes drilled underneath the discovery hole looking for continuity at depth, the adjacent drill fences are lines of relatively shallow holes 400m to the north and south.

Further drilling is required at Matilda to confirm its stratigraphic position relative to the Paddy’s Flat belt. There is more than 5km of strike along this trend to the hinge of the syncline, most of it untested by drilling. To the east of the fold hinge the stratigraphy swings back to the south, down the east side of the Side Well project towards Gabanintha.

Gabanintha trend: On the eastern side of the project, the lithologies corresponding to the Paddy’s Flat belt strike southwards towards Gabanintha, abutting granites and monzogranites of the Walganna and Big Bell suites. South of Side Well there is a series of workings and old mines in this stratigraphic horizon, including Bourke’s Find, Fishers, Tal Val, New Australia and the Gabanintha group of mines.

Within the project this prospective horizon has only been tested by a single line of air-core holes ranging in depth from 16m to 95m. The target horizon is approximately 18km in strike length.

There is no record of any surface sampling on this trend.

Jones Well: Jones Well occurs at the northern end of the Side Well project. The area is structurally complex, with folded BIF abutting a small (6km) ovoid granite. Thin magnetic units wrapping around the granite could be BIF or a contact halo, but in either case the position of a brittle intrusive plug within a large regional structural corridor may create classic dilational positions for gold mineralisation. Smaller areas of low magnetic response adjacent to the BIF suggest there may be other smaller intrusives adding further complexity to the structural setting.

Jones Well is immediately adjacent to Westgold’s Maid Marion deposit, which contains a JORC resource of 700,000t @ 1.52g/t for 34,000 ounces Au[5] . Maid Marion is located approximately 1.2km from the tenement boundary in a similar BIF setting. Since that resource statement was announced, Westgold have released highlights from more recent drilling, including these intersections in the December 2019 quarterly report:

  • 4m @ 5.29g/t Au from 8m in 19MMRC018

  • 4m @ 6.52g/t Au from 8m in 19MMRC023

  • 4m @ 5.23g/t Au from 44m in 19MMWB001.

Jones Well was explored by Dominion and then WMC during the 1990’s, with lag sampling by WMC defining an Au-As anomaly which was subsequently tested with a fence of ten air-core holes. WMC’s exploration report states that the area is covered by a layer of thin pisolitic gravel, with mineralization related to a clay zone and talc-chlorite ultramafic beneath the cover. No significant mineralisation was seen, which may indicate that the lag sampling was ineffective.

High-resolution magnetics will be a useful tool to resolve the structural interpretation in this area, followed by drilling to confirm the lithologies.

Next Steps

  • Approvals for drilling at Mulga Bill have already been submitted, and these should be granted in the coming month.

  • RC drilling will target extensions to the known zones of high-grade mineralisation.

  • Fences of air-core drilling will be used to infill the 400m gaps in coverage, using the supergene dispersion blanket (Au+Cu) to window in on the mineralised corridor.

  • Soil sampling orientation surveys will investigate whether particular soil grainsize fractions and assay techniques provide better results for future soils work.

  • The HeliTEM data will be purchased and re-processed to assist with the regional structural interpretation.

  • A high-resolution magnetic survey will be considered for the Jones Well area.

  • Further drilling pending results of the initial drilling and/or geochemical sampling programs.

Appendix 2 - JORC Code, 2012 Edition Table 1

Section 1 Sampling Techniques and Data

Historical drilling data has been digitally compiled from a series of Annual Technical Reports published by Doray Minerals Limited documenting exploration activities over the Side Well project between 2009-2015. Project history has also been compiled from reports by Dominion Mining Ltd and WMC Resources Ltd between 993 and 1997. Specific reports related to drill results are DMIRS WAMEX report numbers A41188, A43735, A56148, A87660, A90766, A94701 and A99137. A98385 contains details on the airborne geophysical survey undertaken during 2013.

(Criteria in this section apply to all succeeding sections.)

Criteria
Commentary
Sampling techniques
AC sampling techniques are not documented in publicly available reports but it is anticipated that
Doray utilised industry standard techniques.
Diamond drilling was sampled by cutting the core in half with 1m samples sent for analysis.
Sampling techniques are unknown for drillhole HAR3015.
Drilling techniques
Drill intersections reported are a combination of aircore (AC), reverse circulation (RC) and diamond
drilling.
Drill sample recovery
Not recorded.
Logging
All holes were logged for lithology, weathering, alteration, mineralisation and veining. Structural
orientation data was collected from diamond core.
Sub-sampling techniques
and sample preparation
Diamond holes were cut and sampled at a nominal 1m interval length with half core being sent for
analysis.
RC and AC holes were initially sampled as 4m composites with any samples reporting greater than
0.1g/t gold or 0.5% Cu resampled at 1m intervals.
Sample collection, size and analytical methods are deemed appropriate for the style of exploration.
Quality of assay data
and laboratory tests
All samples collected in the field (for Doray AC, RC and DD drilling) were sent to SGS Minerals
Services, in Perth for preparation and analysis. Composite samples were analysed for gold (ppm)
by Aqua Regia (25 gram extraction, AAS (SGS code: ARE133)) and for multi element analysis by
inductively coupled plasma atomic emission spectroscopy (SGS code: ICP12S). One metre re-splits
were analysed by Fire assay (30 gram AAS analysis (SGS code FAA303)) and had the same
multielement analysis as the composite.
To test the confidence in the fire assay re-split results (gold), standards were used by Doray from
ORE Research and Exploration Pty Ltd and included as every 50th sample sent to the laboratory.
Assay metadata for HAR3015 is unavailable
Verification of sampling
and assaying
MBDD001 was designed as twin hole for SWRC006.
Location of data points
Original collar locations for WMC drilling were field checked using handheld GPS by Doray
personnel. It is unclear what technique was utilised to locate Doray’s AC, RC and DD drilling but its
expected at a minimum handheld GPS.
All collar coordinates reported are in GDA94, Zone 50.
Data spacing and
distribution
Data spacing is variable with wide-spaced lines having AC, RC and DD drilling. At the Mulga Bill
prospect a minimum line spacing of 400m was used with AC holes generally spaced between 60-
100m. RC holes have a regular 80m spacing on 400m lines.
Orientation of data in
relation to geological
structure
Mineralisation is comprised of a supergene enriched zone at the base of weathering over a near
vertical, north-south trending intrusive body. Mineralisation within fresh rock is contained within
shear zones at the margin of the intrusion, and within discrete veins. East-West drill orientation is
considered optimal for the currently defined mineralisation.
Sample security
Sample delivery protocols are not recorded.
Audits or reviews
None completed.

Section 2 Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section.)

Criteria Commentary
Mineral tenement and Side Well tenement E51/1905 is a 48-block exploration licence covering an area of 131.8km2
land tenure status immediately east and northeast of Meekatharra in the Murchison province. Zebina Minerals Pty Ltd
currently owns 100% of the tenement with GBR acquiring a 24thMonth option to form a joint-
venture.
Exploration done by Tenement E51/1905 has a protracted exploration history but is relatively unexplored compared to
other parties other regions surrounding Meekathara. The Explroation history by previous explorers has been
described in the technical section of the announcement.
Geology The Side Well tenement group covers a portion of the Meekatharra-Wydgee Greenstone Belt north
of Meekatharra, WA. The north-north-easterly trending Archaean Meekatharra-Wydgee
Greenstone Belt, comprises a succession of metamorphosed mafic to ultramafic and felsic and
sedimentary rocks belonging to the Luke Creek and Mount Farmer Groups.
Over the northern extensions of the belt, sediments belonging to the Proterozoic Yerrida Basin
unconformably overlie Archaean granite-greenstone terrain. Structurally, the belt takes the form of
a syncline known as the Polelle syncline. Younger Archaean granitoids have intrusive contacts with
the greenstone succession and have intersected several zones particularly in the Side Well area.
Within the Side Well tenement group, a largely concealed portion of the north-north-easterly
trending Greenstone Belt is defined, on the basis of drilling and airborne magnetic data, to underlie
the area. The greenstone succession is interpreted to be tightly folded into a south plunging
syncline and is cut by easterly trending Proterozoic dolerite dykes.
There is little to no rock exposure at the Side Well prospect. This area is covered by alluvium and
lacustrine clays, commonly up to 60 metres thick.
Drill hole Information A list of the drill hole coordinates, orientations and intersections reported in this announcement
are provided as an appended table.
Data aggregation No grade truncations were applied to these exploration results.
methods No weighted average techniques are applied to reported intervals
No metal equivalents are used.
Relationship between The orientation of structures and mineralisation is not known with certainty, but majority of the
mineralisation widths drilling drilling was conducted using appropriate perpendicular orientations for interpreted
and intercept lengths mineralisation. Diamond drilling has confirmed a mineralised intrusive body at Side Well has a near
vertical dip and trends broadly north-south. Due to the wide spacing of drill lines exact orientation
is not clear.
Diagrams Refer to figures in announcement.
Balanced reporting It is not practical to report all historical exploration results from the Side Well project. Selected
historical intercepts have been re-reported by GBR to highlight the prospectivity of the region. Full
drillhole details can be found in publicly available historical annual reports.
Other substantive Subsequent to Doray Minerals Limited exiting the project in 2015, private companies have held the
exploration data ground with no significant work being undertaken.
Further work Further work is discussed in the document.
