The plant was placed in care and maintenance by the previous owner, Millennium Minerals, in December 2019. On November 1, 2021, the Golden Eagle Mill was re-started.
In December 2021, Novo released a three-phase mine plan for Beatons Creek which comprised of:
1. Mining of the Beatons Creek Oxide mineral resource. Mining ceased in August 2022 and processing finished in September 2022.
2. Mining of the Beatons Creek free-milling Fresh Resource targeted to commence in Q3 2022 and continue through 2026, following completion of an economic Feasibility Study and granting of mining approvals from the Western Australian government and subject to a final investment decision.
3. Mining of the Golden Eagle deposit commencing and continuing through the transition from Beatons Creek Oxide to Fresh material, depending on timing of Beatons Creek Fresh mining approvals.
November 2, 2022 - The Beatons Creek Feasibility Study has been deferred due to current uncertain economic and regulatory condit |

The Beatons Creek Project area is held through 16 granted and predominantly contiguous tenements totalling 159.7 km²; the tenements include Exploration, Prospecting and Mining Leases held by Nullagine Gold Pty Ltd (12 Exploration and Prospecting Licences); by Grant’s Hill Gold Pty Ltd (four Exploration and Prospecting Licences and one Mining Lease); and Beatons Creek Gold Pty Ltd (three Mining Leases) for durations of four, five and 21 renewal years. Nullagine Gold Pty Ltd, Grant’s Hill Gold Pty Ltd, and Beatons Creek Gold Pty Ltd are all wholly-owned subsidiaries for Novo Resources Corp.

Summary:
PROPERTY GEOLOGY
Diamond drilling during the 2018 field season confirmed the Nullagine sub-basin subdivision of the Hardey Formation by Blake (2001). Mineralisation is restricted to a ~200 m sequence of poorlystratified, poorly-sorted, polymictic, pebble-to-boulder ferruginous conglomerate sequence (P4), which is restricted to an area within a few kilometres of Nullagine (Figure 7.4). The underlying sequence (P3) is of similar composition, but generally finer and including sandstone beds and minor tuffs. The overlying sequence was not separated by Blake and resembles the lower sequence (P3). These beds are characterised by a more regular sediment input and range between sandstone to pebble-conglomerates with a number of extensive tuff horizons.
PROPERTY MINERALISATION
Gold mineralisation within the Beatons Creek conglomerates occurs as fine grains, larger flakes, and rounded particles up to several millimetres across, but rarely exceeding 2 mm. Coarse and fine gold is spatially related to higher concentrations of pyrite, and there seems to be a correlation with gold and the ‘buckshot pyrite’ clast size. Coarse gold particles are regularly visible, and fine gold can readily be panned from crushed matrix material with large pyrite concentrations.
Mineralisation is restricted to fluvial type channel conglomerates or marine lag reworked conglomerates and readily recognisable from outcrop and drill core. The wider Beatons Mineralised ........
Summary:
The gold-bearing conglomerates (mineralised reefs) at the Beatons Creek Project are generally flat lying and have an average thickness of about 1.5m. The mineralised reefs vary in thickness and grade continuity across the mining area. The terrain is undulating with the mineralised reefs daylighting on the flanks of ridges.
Small scale surface and underground mining has been undertaken on the Beatons Creek Project site as early as the late 1800s and more recently some alluvial mining operations have worked the area.
The potential mine development utilises conventional open pit mining methods involving hydraulic excavators, in backhoe configuration, loading trucks. It is assumed that drilling and blasting will be required for the mining of most of the oxide waste and all the fresh mineralised reefs and waste. Dozers are planned to be used to rip oxide waste to assist excavator productivity, push-up mineralised material and push waste to adjacent valley-fill areas.
Plant feed will be trucked to a Mine Ore Pad (MOP) from which it can be road-hauled to the nearby Golden Eagle Mill.
The conceptual mine plan involves the excavation of three types of material:
- Waste material: barren or very low-grade material (<0.5 g/t) that will be hauled to waste dumps outside of the open pit areas or backfilled into excavated open pit voids. Testwork has indicated that 45% of the waste proposed to be mined has been assessed as pot ........

Reserves at February 28, 2019:
Open pit Mineral Resources contain oxide and fresh mineralisation within an optimised shell and constrained within a mineralised wireframe. A cut-off grade of 0.5 g/t gold was applied.
Underground Mineral Resources contain fresh mineralisation outside the optimised shell. Underground resources are constrained to discrete areas of contiguous mineralisation. A cut-off grade for underground resources of 3.5 g/t gold has been applied.
