GBR’s response to the COVID-19 pandemic
As a result of the current economic uncertainty and the range of restrictions in place during the pandemic, the Company has implemented measures to safeguard the business and our community stakeholders.
-
There will be no further field work on the Yilka lands in the Yamarna region until regional travel restrictions are lifted, to help protect communities at Laverton and Cosmo Newberry.
-
Limited field work will continue at the Whiteheads and Mt Jewell projects on a case-by-case basis.
-
The company is working to minimise expenditure until restrictions are lifted.
Exploration Activities
During the quarter the Company completed RC drilling programs at the Whiteheads and Mt Carlon projects, an RC-Diamond drilling program at Winchester and ongoing auger sampling programs at the Whiteheads project. The Company also signed an option and joint venture agreement for the Mt Jewell nickel project adjacent to Whiteheads.
In March the Company announced its withdrawal from the Tarmoola project in order to prioritise exploration on other areas.
Whiteheads Project
Drilling
Two RC holes were drilled at the Drumstick prospect, which is located on the western side of the Whiteheads tenements within the Mithril Resources Lignum Dam earn-in area[1] . The drilling was designed to test beneath nickel anomalism in historic drilling, including 4m @ 1.23% Ni from 44m in hole HMAC021.
The best result from the two holes was 12m @ 0.35% Ni from 64m in hole 20LDRC001A, representing supergene enrichment at the base of weathering. A minor cumulate unit was intersected in hole 20LDRC002 with blebby to matrix pyrrhotite from 88 to 92m.
Auger Geochemistry
In early February the Company announced results from new auger work on the Arsenal Trend, focusing on a gap in historic auger coverage on the eastern side of the project area. The new results have defined a 3.8km-long gold-in-soil anomaly at greater than 10ppb Au, within which two highergrade zones are defined at 25 to 50ppb Au.

The initial auger grid was completed on sample points spaced 50m apart on east-west lines 400m apart. A subsequent round of auger sampling infilled this grid with 200m-spaced lines over the anomalous zone, providing improved definition to the anomaly.
The next stage of exploration for the Arsenal area will be a program of targeted air-core drilling.

Bottom-of-hole drill chip geochemistry
The Company is currently working on a field program to collect bottom-of-hole chips from as many historic drill holes as possible over the Whiteheads project area, with the intention of building a regional multi-element data set that will test for distal alteration footprints to target gold exploration. This is an extremely cost-effective way of building a large-scale regional database which provides valuable information for litho-geochemistry and alteration, which can be tied into existing geological mapping to help target and evaluate gold prospects.

Winchester
Four holes were drilled at Winchester during the quarter for a total of 708m of RC and 183.1m of diamond core. This drilling was co-funded by the WA Government under the Exploration Incentive Scheme. Six holes were originally planned, but the program was cut short to comply with remote travel restrictions associated with the Coronavirus pandemic. Hole details are tabulated below.

Mt Carlon
Drilling
A single fence of 100m-deep RC holes was drilled across the centre of the Eastern Zone anomaly to test for the presence of disseminated nickel sulphides. The Eastern Zone is a 3.5km-long linear feature identified as a chargeable anomaly in the 2019 AEM survey. Chargeable anomalies are one characteristic of disseminated sulphide bodies, an hypothesis that was supported by elevated nickel values in shallow air-core drilling over an ultramafic unit.
Subsequent analysis of the multi-element geochemistry has revealed the nickel values in the assay results are strongly correlated with those for chromium, indicating the nickel is contained within olivine rather than sulphides. Olivine is a silicate mineral associated with mafic and ultramafic lithologies and commonly contains nickel within the mineral lattice. The nickel values at the Eastern Zone anomaly are not associated with sulphide mineralisation.

Mt Jewell
In February the Company announced that an option and joint venture agreement had been signed over the Mt Jewell tenement E27/566, which adjoins the southwestern side of Whiteheads north of Kalgoorlie. Mt Jewell is a Kambalda-style nickel sulphide prospect where previous drilling has intersected sulphide mineralisation as high as 3.38% Ni. There is significant potential to utilise modern, high-powered geophysical techniques such as SQUID EM sensors to discover new sulphide conductors at depth prior to drilling.
Under the terms of the agreement, Great Boulder has 12 months within which to spend a minimum of $20,000 on exploration on Mt Jewell in order to make a decision to proceed to a 75% joint venture for an additional payment of $100,000 to the project vendor. There is also a further milestone payment of $100,000 following the estimation of an inferred nickel resource of 100,000t @ 1.0% Ni or greater.
The Company intends to proceed with the SQUID EM survey during the current quarter.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | Commentary | |
|---|---|---|
| Sampling techniques | Samples were taken manually from the pedogenic carbonate horizon in each auger hole. The | |
| presence of carbonate was confirmed visually and with an acid test, with the acid reaction recorded | ||
| for each location. | ||
| Drilling techniques | Open-hole auger drilling only. | |
| Drill sample recovery | Only visual observations of sample recovery were made. | |
| Logging | Samples were logged for colour, regolith type and acid reaction. | |
| Sub-sampling techniques | Samples were prepared and analysed at Intertek’s Genalysis Assay Laboratories in Kalgoorlie. | |
| and sample preparation | Samples were pulverized so that each samples had a nominal 85% passing 75 microns. The samples | |
| were then analysed using the 25g AR25 33-element package including 1ppb Au. This is an aqua regia | ||
| digest with an MS finish. | ||
| Sample collection, size and analytical methods are deemed appropriate for the style of exploration. | ||
| Quality of assay data | and | All samples were assayed by industry standard methods through commercial laboratories in Australia |
| laboratory tests | (Intertek, Kalgoorlie). | |
| Typical analysis methods are detailed in the previous section and are consider ‘near total’ values. | ||
| Routine ‘standard’ (mineralised pulp) Certified Reference Material (CRM) was inserted by Great | ||
| Boulder at a nominal rate of 1 in 50 samples. Routine ‘blank’ material (unmineralised sand) was | ||

| Mineral tenement | and | The project is located between 45 and 70km north-northwest of Kalgoorlie on the Yarri Road. The | ||
| land tenure status | tenement package is comprised of one active Exploration License and two EL applications. The | |||
| granted tenement E27/544 covers an area of approximately 185km2including up to 15km of strike | ||||
| on a number of potential mineralized trends. Tenement applications E24/588 and E27/622 cover an | ||||
| additional 22 and 10 graticular blocks respectively. Once granted, these tenements will add | ||||
| approximately 49km2to the project area. | ||||
| Exploration tenement E27/544 extents currently surround two prospecting leases held by Scott | ||||
| Wilson, P27/2013 and P27/2213, that are currently under application to be amalgamated into the | ||||
| larger exploration tenement and therefore included in the option agreement. | ||||
| Exploration other parties |
done | by | The Whiteheads project area has been the focus of exploration efforts dating back to the 1960’s. The bulk of the earlier exploration efforts were focussed on the nickel potential of the region following discoveries at the Black Swan, Silver Swan and Carr Boyd deposits. Various exploration campaigns by |
|
| multiple companies utilising differing methods have been undertaken for nickel, VMS and gold | ||||
| targets. The differing exploration and analysis techniques has resulted in a patchwork of exploration | ||||
| datasets that are not easily comparable. | ||||
| Small-scale historical gold workings are present within the tenure that have a protracted history of | ||||
| mining. Publicly available data for these deposits indicate selective mining of high-grade gold veins. | ||||
| Geology | The Whiteheads Project lies proximal to the interpreted boundary between the Archean Kalgoorlie | |||
| and Kurnalpi Terranes of the Eastern Goldfields Superterrane. This boundary also marks the | ||||
| separation of the Boorora (Kalgoorlie Terrane) and Gindalbie (Kurnalpi Terrane) Domains based on | ||||
| volcanic facies relationships. This boundary is marked by a zone of faulting and shearing historically | ||||
| called by various names including the Mt Monger (Swager and Griffin 1994) and Ockerburry Fault | ||||
| (Blewitt and Hitchman 2006). The Boorora Domain is dominated by mafic and ultramafic lithofacies | ||||
| with minor sediments and felsic volcanics. The Gindalbie Domain contains a significant package of | ||||
| bimodal volcanics, sedimentary units and lesser ultramafic lithologies. 3 separate greenstone | ||||
| succession have been recognized within the Gindalbie Domain, with the uppermost bi-modal | ||||
| formation the only one present within the project area. The above successions have experienced at | ||||
| least 4 phases of deformation and display mid-greenschist facies metamorphism. | ||||
| The project area contains a significant amount of transported cover consisting of colluvium, sand | ||||
| plains and laterite. Tertiary aged paleochannels transect the project area. Tertiary duricrust | ||||
| comprises insitu lateritic duricrust to colluvium products derived from insitu material. | ||||
| Several historic workings are located within the project area including the historic Whitehead Find, | ||||
| Patches, Seven Leaders, Lady Betty and Jewellery Box gold workings along with widespread shallow | ||||
| workings. Gold mineralisation is related to extensive shearing and quartz veining along lithological | ||||
| contacts. The Whiteheads Project is located directly along strike to the north of KalNorth Gold Mines | ||||
| Limited’s Lindsay Gold project. No definitive nickel mineralisation has been identified to date within | ||||
| the project area however the Black Swan, Silver Swan and Carr-Boyd Nickel deposits are all located | ||||
| within the region and the project remains prospective for further nickel discoveries. | ||||
| Drill hole Information | A list of the drill hole coordinates, orientations and metrics are provided as an appended table. | |||
