Twenty-seven of the 28 reconnaissance samples taken reported copper grades >1% with a peak value of 17.2% Cu (Sample 134). The same sample, taken near the historic Copper Hill workings, reported a gold value of 2.36g/t Au. Most copper values ranged between 3% and 10% Cu, with only one sample returning a value of less than 1% Cu.
The high-grade copper results are distributed along the three-kilometre length sampled. Malachite with lesser azurite represent the dominant copper species in all samples.

Fourteen of the 29 reconnaissance samples reported promising gold values exceeding 1g/t Au with a peak value of 11.7g/t Au (Sample 148). Five samples reported gold values exceeding 3g/t Au. As with copper, the enriched gold numbers are distributed along the three-kilometre length sampled. Most gold values ranged between 0.1 and 3 g/t Au.
Additionally, promising anomalous cobalt results were returned in two samples, 149 and 150, with 1060 and 1270 ppm Co, respectively.
The samples were mostly collected along the two northwest-trending, subparallel shear zones that partition the eastern ultramafic unit and the tenement. The mineralisation in the area can be likened to that found nearby at Gabanintha although with a lower gold/copper ratio.
Next Steps

About the Copper Hills Project:
The Copper Hills Project is located 42km south of Meekatharra in Western Australia in the Meekatharra-Wydgee Greenstone Belt of the north-eastern Murchison Province. The Project lies immediately southeast of the historic Gabanintha Gold Mine.
Access to Copper Hills from Meekatharra is via the Meekatharra-Sandstone Road and station tracks. The topography is relatively subdued, and sparse vegetation allows for easy access.
The ultramafic dominant Lady Alma Igneous Complex underlies most of the Copper Hills tenure and hosts the Copper Hills and Lady Alma copper gold mineralisation. The Lady Alma Intrusive Complex was assigned to the Meeline Intrusive Suite which also hosts the Windimurra, Barrambie and Youanmi Igneous Complexes.
The mineralisation at Copper Hills is controlled by a north-northwest trending shear zone, dipping moderately to steeply to the east. To the north, the shear rotates towards the northwest. The lithologies of Copper Hills consist of a western gabbro unit and eastern ultramafic unit. The mineralisation is present in both lithologies; it is, however, best developed within the mafic lithologies.
The copper mineralisation is interpreted to be hydrothermal/ structural and consists of predominantly chalcopyrite with lesser pyrite ± pyrrhotite associated with quartz veining and as anastomosing thin veinlets. To a lesser extent, small vein breccias are additionally associated with mineralisation. Individual veinlets are interpreted as being relatively discontinuous within the structure, and higher-grade zones within the historical drilling represent zones of greater vein density within zones of localised dilation.
Historical drilling has confirmed the presence of significant copper and gold mineralisation over a strike length of at least 2.2km and is open to the northwest. A shallow northerly plunge component to the mineralisation is evident.

| Criteria | JORC Code explanation | Comments |
|---|---|---|
| Sampling techniques |
· Nature and quality of sampling (eg 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. |
Reconnaissance rock chip sampling conducted by visual identification of mineralised material to gain an understanding of the tenor of mineralisation. |

Mithrill Resources Ltd explored the Copper Hills area as part of their larger Copper Hills Project. Prior to Mithrill, Silver Swan Group (2008-2013) conducted extensive geochemical sampling and drilling over a larger combined Meekatharra East Tenement Group (group reporting) which covered the Copper Hills prospect. Historical drilling at Copper Hills Prospect was by Union Oil-Homestake JV in the late 1960s to early 1970s reported the following broad shear hosted copper mineralisation in two diamond holes: • CD6: 101m @ 0.46% Cu from 63m oIncluding 16.1m @ 0.99% Cu from 64.5m & 17.8m @ 0.86% Cu from 145.7m • CD7: 13.7m @ 0.95% Cu from 9.1m & 12.5m @ 1.45% Cu from 39.9m . |
| Geology | ·Deposit type, geological setting and style of mineralisation. |
The copper and gold mineralisation at Copper Hills is controlled by a north-northwest trending shear zone, dipping moderately to steeply to the east. To the north the shear rotates towards more of a northwest orientation. The lithologies of Copper Hills consist of a gabbro unit to the east and an ultramafic unit to the west. The mineralisation is interpreted to be hydrothermal/ structural in nature and consists of predominantly chalcopyrite with lesser pyrite ± pyrrhotite associated with quartz veining and as anastomosing thin veinlets. |

·In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. |
No modification of results was conducted. |
| ·Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. |
No aggregation of data was conducted. | |
| ·The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalence are reported. | |
| Relationship between mineralisation widths and intercept lengths |
· These relationships are particularly important in the reporting of Exploration Results. |
Further work to establish the key geological parameters is warranted |
| · If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. |
No drilling reported | |
