Bryah Resources Limited (ASX: BYH, “the Company” or “Bryah”) is pleased to announce its updated Manganese Mineral Resource. Bryah owns 49% of the manganese rights in a Joint Venture with OM (Manganese) Ltd, (“OMM”) a wholly owned subsidiary of OM Holdings Limited (ASX: OMH).
HIGHLIGHTS
- Total Inferred and Indicated JORC 2012 compliant Mineral Resource Estimate 3.07 Million tonnes (Mt) at 20.2% Mn
- Indicated Resource increased by 91% and Inferred Resource increased by 32%
- Mineral Resources estimated at Area 74, Redrum, Brumby Creek, Black Hill and Horseshoe areas - 5 prospects in total
- Manganese defined as a critical mineral by many countries, including the United States for its use in steelmaking and batteries1
MANGANESE EXPLORATION - WHAT’S COMING UP?
- Mining Licence applications lodged in addition to existing granted mining lease at Horseshoe Manganese M52/806
- Environmental approvals progressing
- Ongoing drilling to extend the current Mineral Resource
- Further metallurgical test work to define beneficiation yields
Commenting on the updated Mineral Resource, Bryah CEO Ashley Jones said:
“We are very pleased to announce an updated JORC Mineral Resource Estimate for the Bryah Basin JV Project with OM Manganese. The JV with OMM has allowed us to complete substantial extensional and infill resource drilling at our prospects, delivering a 67% increase in the combined Indicated and Inferred Mineral Resource.
Importantly, we have now achieved a ‘critical mass’ (3 Mt) that allows the JV to progress mining studies and planning to the production stage. The Horseshoe deposits are located within an active mining lease (M 52/806), with recent mining license applications now covering the remainder of deposits included in this Mineral Resource (M 52/1087 and M 52/1088).
The 15% manganese cut-off grade used in this MRE is superior to many of our peers with potentially greater yields to make a saleable manganese product. Historical production at the Horseshoe pits gives us further confidence in achieving a successful mining operation.
We look forward to drill-testing more gradient array induced polarisation and geologically mapped exploration targets and will conduct further resource extension drilling throughout the remainder of 2023. We believe we have just started to unlock the true manganese production potential of the Bryah Basin and look forward to some fruitful years ahead.”

All the Mineral Resources are now including on either granted or mining licences under application.
- Mineral Resource includes 0.65 Mt at 20.0% Mn on a granted Mining Lease M52/806
- Mineral Resource includes 2.42 Mt at 20.2% Mn on Mining License Applications M52/1087 andM52/1088
- Over 67 % of the resources are in the Indicated Mineral Resource category.
- Indicated Mineral Resources of 2.07Mt at 20.9% Mn and Inferred Mineral Resources of 0.99Mt at 18.6% Mn.

High grade Massive Sulphide Intercepts Confirmed at Oval
HIGHLIGHTS:
- OVD027 confirms the continution of high grade massive sulphide from OVD0211 with an intercept of 6.1 metres of 4.16% Cu, 3.51% Ni, 0.G3g/t E3, and 0.13% Co from G8.2 metres encountered between broader high grade zones of:
- A dense disseminated intercept - 26.2 metres of 0.44% Cu, 0.52% Ni, 0.12g/t E3, and 0.03% Co from 72.0 metres and
- A net textured intercept - 15.3 metres of 1.15% Cu, 0.79% Ni, 0.35g/t E3, and 0.04% Co from 104.3 metres;
- A high grade broad intersection is confirmed at the central part of the Oval area by OVD026. It includes a massive sulphide intercept in hole OVD026 of 1.8 metres of 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co from 105.0 metres within broader mineralisation of:
- 19.8 metres of 1.23% Cu, 0.98% Ni, 0.36g/t E3, and 0.05% Co from 91.2 metres.
OVD026 is located 100 metres northwest of the previously announced 8.8 metres of massive sulphide identified in drillhole OVD021.
On completion of the Phase 2 exploration work and receipt of all assays, Managing Director Gan-Ochir Zunduisuren, commented:“The 2024 Phase 1 and 2 drilling and exploration programs have confirmed the broad presence of high-grade mineralisation in the Oval gabbroic intrusion. The grades intercepted in some of the drillholes are exceptional and may be indicative of broader potential over a larger area, given Oval is a greenfields discovery.
The 2025 exploration program will focus on obtaining information on the size/metal content potential of the Oval Cu-Ni-PGE mineral system as well as targeting the possible deeper magmatic sources at Oval. Broader exploration is also planned at potential extensions of Oval and nearby look-a-like prospects. We look forward to updating shareholders on progress, with drilling expected to commence in around 8 weeks”.
Summary of Phase 2 exploration drilling at Oval Cu-Ni-PGE project
The Company’s recent drilling work has predominantly focused on finding high-grade mineralisation in the olivine-amphibole gabbro at the Oval project. The multiple intercepts of massive sulphide mineralisation with different ratios of metal contents throughout the Oval gabbroic intrusion is highly encouraging for the presence of one or more deeper sources of high grade mineralisation in the opinion of ABM.

Drillhole OVD02c
Drillhole OVD026 was designed to test the Down-Hole Electromagnetic (DHEM) conductor plate identified as OVD007_L2_B (reinterpretation of OVD007_L2_A2 by Southern Geoscience Consultants), which exhibits a conductance of 1,000 siemens. The drilling intersected a total of 1G.8 metres of mineralisation with 1.23% Cu, 0.G8% Ni, 0.36g/t E3, and 0.05% Co from G1.2 metres including;
- 4.8 metres of @ 0.45% Cu, 0.43% of Ni, 0.14g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 91.2 metres,
- 6.6 metres of @ 1.56% Cu, 0.G0% Ni, 0.50g/t E3, and 0.04% Co of net textured mineralisation from G6.0 metres,
- 2.4 metres of @ 1.52% Cu, 1.3G% Ni, 0.43g/t E3, and 0.07% Co of semi massive sulphide mineralisation from 102.6 metres,
- 1.8 metres of @ 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co of massive sulphide mineralisation from 105.0 metres, and
- 4.2 metres of @ 0.57% Cu, 0.45% of Ni, 0.21g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 106.9 metres (Table 1 provides a detailed breakdown of mineralisation intervals).
OVD026 is located in the Oval area, which is approximately 100 metres northwest of the previous intersection identified in drillhole OVD0213. This intercept may represent an extension of the known massive sulphide mineralisation in the Oval area and highlights the potential for further expansion of massive sulphide zones within the broader prospect area (Figures 1 and 3).
