West Australian gold exploration and development company, Rox Resources Limited (“Rox” or “the Company”) (ASX: RXL), has received the final batch of assays from its 11,000m DD and RC program at the Youanmi Gold Project in WA.
- The latest batch of assays have been received from the 11,000m drilling program (both diamond core and reverse circulation) at the high gold-grade Youanmi Gold Project, located centrally in Western Australia’s prolific gold fields
- The recently-completed infill/exploration program aimed to improve resource confidence and open up corridors for resource growth; to underpin the Definitive Feasibility Study (DFS), and, additionally, provide sample material for ongoing metallurgical optimisation test-work for the DFS program
- Latest highlights from the program include:
- RXDD131: 4.38m @ 19.07 g/t Au from 387.98m,
- incl. 1.73m @ 41.43 g/t Au from 389.96m
- RXDD119: 4.56m @ 14.60 g/t Au from 220.64m
- RXDD115: 2.99m @ 21.11 g/t Au from 249.88m
- RXDD119: 4.0m @ 7.37 g/t Au from 162.0m
- RXDD132: 7.19m @ 3.90 g/t Au from 263.61m
- RXDD133: 2.83m @ 6.53 g/t Au from 431.00m
- RXDD128: 3.82m @ 4.51 g/t Au from 364.59m,
- incl. 1.73m @ 8.22 g/t Au from 364.59m
- incl. 1.73m @ 8.22 g/t Au from 364.59m
- RXDD122: 0.95m @ 13.50 g/t Au from 204.44m
- §These results further demonstrate the continuity of high- grade gold mineralisation along the Youanmi greenstone belt belt, and the potential for resource growth both at depth and along-strike, with discovery potential to the south
- 35,000m Step-up drill campaign well underway with the plan to bring forward ounces and increase the mine plan
The program focused on converting Inferred stopes at Pollard, United North and Youanmi Main to higher confidence Indicated classification and providing material for metallurgical testing for the upcoming Definitive Feasibility Study (DFS) – on track for H2 CY25.
This final consignment of diamond assay results are the fourth batch of assays results returned from the drill program and have been entirely drilled from the Pollard, Youanmi and United North areas (Figure 1).
Rox Resources’ Chief Executive Officer, Phillip Wilding, commented:
“It’s pleasing to round out the 11,000m RD and DD drilling program with another batch of excellent intercepts.
“More importantly, the program has significantly improved our knowledge of the high grade and underexplored Youanmi ore system, and shown that mineralisation remains open at depth.
“Next steps are to convert Inferred areas of the Resource to the higher confidence Indicated classification, and finalise key intercepts of sample material for metallurgical test work to feed into the Youanmi DFS.
“We are excited to have commenced the 35,000m Step-up program to potentially bring forward ounces in the mine plan and significantly increase the size of the Pollard ore zone.”
Youanmi Major Growth Drill program
Resource drilling has focused on converting selected Inferred stopes in the current Mineral Resource of 16.2Mt at 4.4g/t Au for 2.3Moz (Indicated: 10.7Mt at 4.5g/t Au for 1.6 Moz : Inferred 5.5Mt at 4.2g/t Au for 0.7 Moz) 1 to higher confidence Indicated classification at Pollard, United North and Youanmi Main as shown in plan on Figure 1. The drilling has also provided both sample material for metallurgical testing and valuable geological data for the pending Definitive Feasibility Study (“DFS”) planned for second half of 2025.

Outside of the immediate resource area, drilling was also conducted on near-mine exploration and focused on the Youanmi South prospect area, or Paddy’s Lode, first reporting high-grade intercepts in 20232. The drilling at Paddy’s has complimented the Company’s exploration strategy moving south along the Main Lode Shear Zone (MLSZ) and adding additional gold ounces to the Resource. Youanmi South has the potential to grow the Resource above the 103kozpa Production Target outlined in the recently completed Pre-Feasibility Study (“PFS”)3.

Nickel-Copper Anomalies at Iguatu North Project
Highlights
Work Undertaken
- Assays received from 52 regional stream sediment samples at Iguatu North Project with widespread coincident Copper-Nickel anomalies supported by Cobalt, Palladium and Chromium anomalies.
- High order Ni-Cu anomalies over 3 km long surrounded by lower order anomalies.
- Geochemical anomalies clearly indicate the priority area for initial follow up work to define mineralised drill targets.

David Evans, Managing Director, commented:
We are delighted to identify potential for Copper-Nickel-PGE mineralisation within our Iguatu tenements. The proximity of these anomalies to the Pedra Branca PGE deposit, just 25 km northeast, is highly encouraging.
With samples returning copper and nickel values up to two and four times higher than the program's average, respectively, these results also present an opportunity for Gold Mountain to add exciting Copper-Nickel-PGE targets to its existing lithium and rare earth prospects.
Future Workplan
- Iguatu North Ni-Cu anomalous areas will be tested by infill stream sediment and soil sampling followed by IP or other ground or airborne geophysics to define specific drill targets.
- Mapping of the full extent of the mafic intrusives interpreted to be present will be undertaken.
- Drilling will be undertaken on defined targets.
Details
Stream sediment sampling was carried out in a broad network of samples over the Iguatu North tenements, which were initially acquired for their Copper and Lithium potential.
Interpretation of results consisted of determining populations of results considered to be anomalous and then separating anomalous results for copper and carrying out element correlations on the copper anomalous samples.
Table 1 shows the correlation coefficients for a series of elements considered important for mafic intrusive hosted nickel-copper-PGE mineralisation and for IOCG style mineralisation.

Terra Balcanica Drills 436 g/t AgEq Over 19.6 m at Antimony-Silver Discovery in Bosnia
- Drillhole BREDD002 returned 436 g/t AgEq over 19.6 m including 746 g/t AgEq and 1.42 wt.% Sb over 9.8 m;
- Another mineralization style confirmed at Brezani in addition to the gold skarn with 0.61 g/t AuEq over 88.0 m from surface (see Company’s news release dated 24th January 2023);
- Mineralization trends towards surface and daylights in a topographic depression with As-Bi-Sb-Te anomalism in soil samples with a shallow “boiling-zone” drill target (Figure 1);
- 4 shallow drillholes, aimed at expanding the footprint of the gold skarn have been completed within the > 800 m strike length gold in soil anomaly, with assay results pending.
Terra Balcanica CEO, Dr. Aleksandar Mišković, comments:
" We are very pleased with the polymetallic assays from an interval thrice as wide as that average reported at our other Viogor-Zanik target at Cumavici. Not only have we discovered a new type of mineralization that shallows toward northeast, and as such could be easily explored from top down, but we have also confirmed the significant presence of antimony at Brezani which continues to be a scarce commodity worldwide due to supply issues and trade restrictions imposed on certain countries. Now, the drill-confirmed surficial Au bearing skarn is confirmed to be underlain by the significant fault-hosted polymetallic mineralization which itself is underpinned by andesitic porphyry. It is encouraging to see this resulted from the very first drill hole leaving a lot of upside potential at Brezani as Terra releases additional assays from the four shallower intercepts drilled into the surficial skarn."

Drillcore Observations

The zone of mineralization from 482.1 m consists of banded veins and sulphide cemented breccias with characteristics of both low and intermediate sulphidation epithermal deposits. The upper vein contact is sharp with minimal alteration progressing into the hornfels, whereas the vein footwall is brecciated and hosts strong clay alteration. The margins of the vein host repeating bands of chalcedonic quartz-rhodochrosite-calcite and sulphides/sulphosalts stibnite-pyrite-arsenopyrite-sphalerite-galena-jamesonite (Figure 2). The centre of the structure is dominated by hydrothermal breccia with a sulphide-quartz-carbonate cement. Clasts are banded vein fragments.
Figure 1. Section through the Brezani target illustrating conductivity and the 95th percentile magnetic shell. Drillhole BREDD002 is shown, with a tabular conductivity feature extending to the ENE from the epithermal mineralized interval. Conductivity feature is interpreted as the continuation of the host structure with increased conductivity due to sulphide and clay within the broken rock mass. It passes through a break in the magnetics, which is further evidence of structural control.
Future Exploration Program
2023 drilling at the Brezani target uncovered a new style of mineralization at the contact between the skarn-hornfels package and underlying chlorite-sericite altered diorites. The epithermal mineralization encountered 482.1 m downhole is interpreted to shallow to the ENE creating a conductivity feature which passes through a magnetic low. A topographic low with an anomalous epithermal assemblage in soil and rock chip geochemistry is interpreted as the surface expression. Future drilling efforts will aim to intersect the epithermal mineralization shallow and explore for a “boiling zone” where precious metals may have been favourably precipitated.

QA/QC
Half core (HQ3) samples were delivered to ALS Bor, Serbia for sample preparation and subsequent wet chemical analysis at the Loughrea laboratory in Ireland, an ISO/IEC 17025:2017 certified test facility. Sample preparation PREP-31BY method involved crushing the core to 70% less than 2 mm, rotary split 1.0 kg and pulverizing the split to greater than 85% passing 75 microns. Silver and base metals were analysed by ICP MS after a four-acid digest (ME-MS61). Gold was assayed by 30g fire assay with ICP AES finish (Au-ICP21). Over limit samples for base metals were re-analysed by the four-acid digest ICP-AES analyses termed ME-OG62. Control samples comprising the certified reference material CDN-ME-1810 (Canadian Resource Labs Ltd.), quarter core field duplicates and blanks were inserted at a rate of 9 % and investigated as part of the Company’s quality assurance and quality control program.
