Bryah Resources Limited (ASX: BYH, “Bryah” or “the Company”) is pleased to advise the results of a review of historical exploration and drilling results which were completed by Australian Vanadium Limited( ASX: AVL) in 2013 within the Company’s Gabanintha Project, approximately 50km south of the town of Meekatharra in central Western Australia.
- Close spaced 25m lines ground magnetics survey completed at target area.
- Copper mineralisation intersected at Copper Hills South Prospect in 5 historical drill holes. Best intersection reported in 20131was:
- GRC1152 - 18 metres (7-25m) @ 0.42% Cu, including 2m (20-22m) @ 2.19% Cu
- Recent re-evaluation of 2013 drilling data has identified more copper anomalism than reported earlier. Additional intervals within hole GRC1152 include:
- 6 metres (34-40m) @ 0.27% Cu
- 7 metres (45-52m) @ 0.20% Cu
- 4 metres (149-153m) @ 0.22% Cu
- Copper mineralisation in GRC1152 is open in all directions
- 2013 drilling program was designed to test a strong geophysical anomaly associated with an ultramafic unit
- Historical reports in WAMEX show bottom of hole Copper assays up to 1.8% Cu
- Follow up Targeted RC drilling planned Q2 2023
The Copper Hills South Prospect (formerly Gabanintha East) is located 1.5 kilometres south of the Copper Hills Prospect on a granted mining lease M51/878 (see Figure 1).
The Copper Hills Prospect is currently being explored by Peak Minerals Limited (ASX: PUA).

Bryah holds a suite of mineral rights over tenements held by AVL covering 148km² (see Figure 1). Bryah’s mineral rights are for all minerals, excluding vanadium, titanium, cobalt, chromium, uranium, lithium, tantalum, iron ore and manganese. The vanadium-titanium-magnetite deposit is approximately 11.5km long within the Project with most of this lying on Mining Lease M51/878 which was granted in 2020.
Commenting on the results of the recent findings, CEO Ashley Jones said:
“We see very attractive fundamentals in the copper market, through the transition to electrification, hence Bryah’s geological team started re-assessing our Gabanintha tenements’ copper potential. A review of 2013 drill data showed great prospectivity south of Copper Hills. A ground magnetic survey was completed to better understand the 2013 geological interpretation which targeted a deep Induced Polarisation anomaly at Copper Hills South project. The highlight of the previous drilling was 2m at 2.1% Cu, and was part intersected mineralisation over multiple intersections above 0.2% Cu. The combined historical data, together with the newly acquired ground magnetics, has been used to define our new drill targets.”
Previous Exploration
In 2012, Australian Vanadium Limited (AVL) (formerly named Yellow Rock Resources Limited) completed a HELITEM helicopter-borne electromagnetic (EM) and magnetic survey over the Gabanintha Project. The aim of the geophysical survey was to gain a better understanding of the distribution of the structures and lithological units in the bedrock, define the location and extent of bedrock conductors, identify areas for potential mineralisation, and quantitative geological modelling of the layered gabbro within the project area.
Modelling of the HELITEM survey data led to the identification of an EM zone, interpreted to be an ultramafic unit, parallel to, and east of AVL’s Vanadium-Titanium-Magnetite deposit.2
A follow-up Induced Polarisation (IP) survey conducted in 2013 confirmed the strong EM anomaly in the area. The centre of the IP survey anomaly occurs at 100m to 300m below surface for a strike length exceeding 2 kilometres3(see Figure 3). The anomaly appears to be open to the south east, beyond the edge of the IP survey area.
The potential that substantial sulphide mineralisation may occur and be associated with a left stepping structural “jog”, where co-incident strong to very strong modelled IP and strong magnetic anomalies occur, lead AVL to complete a program of 5 scout Reverse Circulation (RC) drill holes in 2013.

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).
