Morello ‐ Rocha and Fortuna - Milestone 2
Follow‐up RC drilling was completed and identified broad zones of low‐grade mineralisation.
Gold Road Executive Director ‐ Discovery & Growth Justin Osborne commented: "We are pleased to have finished the 2019 exploration programme. We are confident the excellent results from the Gruyere extensional drilling will have a positive impact on the next Mineral Resource update anticipated in early 2020. We are in the process of reviewing the results from our ongoing Yamarna exploration which confirmed gold mineralisation in multiple locations. The work completed this year confirmed our belief in the Southern Project Area as having the greatest prospectivity. We anticipate the majority of the 2020 exploration budget will be focussed on this area with drilling scheduled to commence in January on our reranked high priority targets.
- Diamond and RC intersections for Gruyere reported as geologically selected, other projects reported at a 0.5 g/t cut‐off including up to 2 metres of samples below that cut‐off unless otherwise stated. Refer to Tables in Appendices for individual grades >10 g/t Au. All intersections reported uncut.

Gruyere JV (50% Gold Road)
Gruyere Mine Exploration
An expanded 11,000 metre diamond and RC drilling programme (Figure 2) designed to extend the Indicated Resource below the current Ore Reserve pit design and delineate the limits of mineralisation at the southern and northern extremities of the Gruyere Deposit is now complete.
Assays from the final 15 holes of a total 21 hole programme have been received confirming the continuity of the Gruyere mineralisation as observed in the open pit and previous drill programmes. The drill results provide confidence that the Indicated Resource will extend below the limits of the current Ore Reserve pit design allowing for future strategic evaluation and mine optimisation. It is anticipated that an updated Mineral Resource will be reported in early 2020 which will reflect this.
Significant widths at higher than the average Resource grade have been intersected in the northern portion of the Resource, including 41.4 metres at 2.52 g/t Au from 372.3 metres (19GY0365), 47.8 metres at 1.93 g/t Au from
302.1 metres (19GY0343), and 41.7 metres at 1.40 g/t Au from 561.3 metres (19GY0366). These results are all located beyond the current pit design.
Drilling in the central area of the deposit confirmed the consistent wide zones of mineralisation characteristic of Gruyere, with best intercepts of 149.6 metres at 1.46 g/t Au from 437.4 metres, including 102.4 metres at 1.72 g/t Au from 469.8 metres (19GY0363); 159.5 metres at 1.25 g/t Au from 418.9 metres (19GY0361), and 183.0 metres at 0.99 g/t Au from 378.0 metres, including 56.0 metres at 1.67 g/t Au from 468.0 metres (19GY0352).

SOUTHERN PROJECT AREA (100% Gold Road)
Warbler - Yaffler South
The Warbler prospect is defined by a northwest‐southeast striking shear zone situated approximately 300 metres west of the Yaffler South prospect and 20 kilometres along strike on the Yamarna Shear Zone to the south of Gilmour. In August 2019, four RC holes intersected coherent and consistent mineralisation across one traverse on a newly discovered trend. Shallow high‐grade
mineralisation was intersected at the sheared stratigraphic contact between dolerite and intermediate sediments within the regolith and bedrock. All four holes intersected gold mineralisation with the best intersection returning 11 metres at 5.94 g/t Au from 74 metres as previously reported2.
An 11 hole follow‐up RC and diamond drilling programme was completed in the December 2019 quarter on step out section lines between 50 and 100 metres to the north and south of the original discovery traverse. Drilling confirmed continuity, geometry and widths of the mineralisation along strike and down dip at lower grade than the discovery section (Figure 3). Further drilling along this newly identified trend is planned for the first quarter of 2020.

Morello-Rocha
Results were returned from an RC drilling programme testing the Rocha target at the northern extent of the Morello trend. The target is adjacent to the Rocha Fault, which is the next major structure cross‐cutting and displacing the mineralised Gilmour‐Morello trend 800 metres north of the 260,000 ounce Gilmour Deposit. A broad zone of low‐grade mineralisation indicating the presence of gold
mineralising fluids has been confirmed at Rocha, hosted in the same sandstone unit as Morello. Multiple intersections were encountered which included 10 metres at 3.08 g/t Au from 90 metres (19WDRC0250), 29 metres at 0.38 g/t Au from 80 metres (19WDRC0245) and 28 metres at 0.30 g/t from 151 metres (19WDRC026)3. Ongoing evaluation will be used to target potential follow‐up drilling in 2020.
Fortuna
A first pass RC drill programme was completed on the Fortuna target approximately 1.5 kilometres south of Smokebush. The programme was following up on a coincident arsenic‐antimony geochemical anomaly identified through aircore drilling in the first half of 2019. Zones of low‐level
gold anomalism confirmed a fertile mineralised structure adjacent to, or part of, the regionally significant Smokebush Shear. Geological interpretation is ongoing and will be used to identify further targets in the area for follow‐up drill testing in 2020.
Yamarna Geochemical and Geophysical Programmes
To support the Yamarna geological interpretation and targeting of the next discoveries, Gold Road continued its programme of geochemical sampling and mapping of basement geology through aircore drilling across the Yamarna Greenstone Belt. An EIS co‐funded 13 kilometre aircore traverse testing
stratigraphy in an area that has received little drilling to date was completed. In the Southern Project Area, aircore drilling to aid definition of the regional stratigraphy was completed on the Hopwood, Riviera, Hirono and Grevillea prospects.
Assay results for all completed aircore programmes have been received. Ongoing geological interpretation and targeting of the results will be incorporated into the 2020 exploration programme. The southern project area will continue to be the priority focus for exploration activities in 2020.
During the December 2019 quarter, a large gravity survey covering approximately 1,675 square kilometres to acquire 18,350 data points was completed. This information will improve the resolution of the targeting dataset enabling detailed interpretation of the bedrock geology and deep‐seated geological structures. When used in conjunction with the existing regional aeromagnetic and extensive geochemistry data, the Company can enhance the quality and predictive effectiveness of the ranking and prioritisation of the gold targets to be tested through 2020.

as a percentage. Recovery of the samples was good, generally | |
estimated to be full, except for some sample loss at the top of the hole. | |

Geology | The prospects are located in the Yamarna Terrane of the Archaean |
Deposit type, geological setting and style of mineralisation. | Yilgarn Craton of WA, under varying depths (0 to +30 m) of recent cover. |
The mafic‐intermediate volcano‐sedimentary sequence of the Yamarna | |
Greenstone Belt has been multiply deformed and metamorphosed to | |
Lower Amphibolite grade and intruded by later porphyries/granitoids. | |
The Archaean sequence is considered prospective for structurally | |
controlled primary orogenic gold mineralisation, as well as remobilised | |
supergene gold due to subsequent Mesozoic weathering. | |
The Gruyere Deposit comprises a narrow to wide porphyry intrusive | |
dyke (Gruyere Porphyry - a Quartz Monzonite) which is between 35 and | |
190 m in width and which strikes over a current known length of 2,200 | |
m. The Gruyere Porphyry dips steeply (65‐80 degrees) to the east. A | |
sequence of intermediate to mafic volcaniclastic rocks defines the | |
stratigraphy to the west of the intrusive and intermediate to mafic | |
volcanics and a tholeiitic basalt unit occur to the east. | |
Mineralisation is confined ubiquitously to the Gruyere Porphyry and is | |
associated with pervasive overprinting albite‐sericite‐chlorite‐pyrite | |
(±pyrhhotite±arsenopyrite) alteration which has obliterated the | |
primary texture of the rock. Minor fine quartz‐carbonate veining occurs | |
throughout. Pyrite is the primary sulphide mineral and some visible | |
gold has been observed in logged diamond drill core. | |
The Gruyere Deposit comprises coincident structural and geochemical | |
targets within a major regional‐scale structural corridor associated with | |
the Dorothy Hills Shear Zone. This zone occurs within the Dorothy Hills | |
Greenstone Belt at Yamarna in the eastern part of the Archaean Yilgarn | |
Craton. The Dorothy Hills Greenstone is the most easterly known | |
occurrence of outcropping to sub‐cropping greenstone in the Yilgarn | |
province of Western Australia. | |
Mineralisation at Wanderrie area (Rocha prospect is in this trend) is a | |
shear hosted style mineralisation that sits within several stratigraphic | |
positions. These can be found in mafic sediment, volcanic and dolerite | |
sequences in the north (Santana and Satriani) and within dacitic and | |
felsic sedimentary packages in the south (Gilmour - Morello). | |
Mineralisation is typically associated within and proximal to zones of | |
high strain, biotite - sericite - chlorite - albite alteration, with a pyrite | |
- pyrrhotite dominant system with accessory arsenopyrite. | |
The Fortuna prospect is associated with a regional 320 degree striking | |
shear. Mineralisation is typically associated within and proximal to | |
zones of high strain, biotite - sericite - chlorite - albite alteration, with | |
a pyrite - pyrrhotite dominant system with accessory arsenopyrite. No | |
discernible thick zones of veining are noted and mineralisation is | |
characterised by diffuse sulphides with disseminated gold. | |

Gruyere: Mineralisation is hosted within a steep east‐dipping, N‐S | |
striking porphyry. The porphyry is mineralised almost ubiquitously at | |
greater than 0.3 g/t Au and is characterised by pervasive sub‐vertical | |
shear fabrics and sericite‐chlorite‐biotite‐albite alteration with | |
accessory sulphides dominated by pyrite‐pyrrhotite‐arsenopyrite. | |
Higher grade zones occur in alteration packages characterised by albite‐ | |
pyrrhotite‐arsenopyrite alteration and quartz and quartz‐carbonate | |
veining. These vein packages dip at approximately ‐450 to the SSE, with | |
strike extents of over 100 m. | |
The general drill direction of 600 to 2700 is approximately perpendicular | |
to the main alteration packages and is a suitable drilling direction to | |
avoid directional biases. | |
