Rox Resources Strikes Gold: High-Grade Intersections Expand Youanmi's Potential
Rox Resources (ASX: RXL) has announced multiple high-grade gold discoveries at its Youanmi Gold Project, expanding the known mineralisation around its substantial 2.2 million ounce resource base.
Fresh Discoveries Bolster One of Australia's Highest-Grade Gold Projects
Recent drilling has delivered significant results from both brownfield and regional targets, reinforcing Youanmi's status as one of Australia's highest-grade emerging gold projects. The program follows Rox's recently announced Mineral Resource Estimate (MRE) of 2.2 million ounces at an impressive 5.6 g/t gold (Indicated and Inferred).
Key intersections from the latest drilling include:
- 5.30m @ 6.34g/t gold near the Bunker pit
- 4.12m @ 14.86g/t gold at the Midway prospect
- 3.00m @ 19.05g/t gold at the Currans prospect, 20km south of Youanmi
- 6.00m @ 2.32g/t gold including 0.49m @ 17.50g/t gold from a previously untested IP anomaly
These results highlight the potential for significant resource growth beyond the current MRE boundaries.
"Our exploration team have been busy on the ground at Youanmi as we have expanded our drilling efforts further into our tenement package," said Managing Director & CEO Phill Wilding. "We are excited to have discovered multiple gold intersections outside the resource south of the main pit, which further highlights the potential to grow the system at Youanmi."
New Style of Mineralisation Discovered at Youanmi South
At Youanmi South, drill hole RXDD217 targeted a large chargeable IP anomaly and intersected gold-bearing semi-massive pyrite, returning 6m @ 2.32g/t gold including 0.49m @ 17.50g/t gold. This represents a potentially new style of gold mineralisation at Youanmi, where most known mineralisation is shear-zone hosted.
This discovery opens up new exploration pathways across the Youanmi complex, with additional drilling already underway to test for continuations of this mineralisation style.
Bunker Pit Expansion Potential
Drilling at the Bunker pit has identified strong mineralisation outside of known lodes, with hole RXDD228 returning 5.30m @ 6.34g/t gold from just 84.2m depth. Previous drilling to the west of the Bunker pit has not exceeded transported cover depth, highlighting this area as highly prospective for resource expansion.
Additional drilling is continuing to test along strike of this intersection, with similar geology encountered in subsequent holes.
Understanding Gold Mineralisation: Induced Polarisation (IP) Surveys
Induced Polarisation (IP) is a geophysical survey method that measures the electrical chargeability of subsurface materials. In gold exploration, IP surveys are particularly effective at identifying disseminated sulfide minerals, which often accompany gold mineralisation.
When conducting IP surveys, an electrical current is sent into the ground through electrodes. The way the ground responds to this current can indicate the presence of certain minerals. Specifically, sulfide minerals like pyrite (often associated with gold) can store electrical charge temporarily, creating a measurable "chargeability" effect.
At Youanmi, Rox's use of IP surveys has led to the discovery of new gold-bearing zones, as demonstrated by the successful targeting of the large chargeable anomaly with drill hole RXDD217. This technique has proven valuable for identifying mineralisation beneath cover and outside known resource areas.
The IP survey at Youanmi South identified a significant chargeable anomaly along line L1060N, which was subsequently tested with diamond drilling. The resulting discovery of gold-bearing semi-massive pyrite validates the effectiveness of this exploration technique in identifying potential mineralisation that might otherwise remain undetected.
IP surveys complement other exploration methods by providing information about the subsurface that might not be apparent from surface geology or other geophysical methods. This integrated approach to exploration increases the likelihood of discovering additional resources at Youanmi.
Regional Potential Confirmed at Currans
Beyond the main Youanmi resource area, Rox has completed a 664m diamond drill campaign at the Currans prospect, located approximately 20km south of Youanmi and positioned between the company's main project and Ramelius Resources' Penny West deposit.
The program delivered outstanding results, including 3m @ 19.05g/t gold from just 57.7m depth at the Red White Blue prospect. This high-grade mineralisation was associated with bucky white quartz veining and adjacent ductile shearing.
The structural data collected from these diamond holes has provided valuable insights into the controls on gold mineralisation, with lineations indicating a moderate east-northeast plunge control. This information will guide future drilling efforts to target extensions of the high-grade zones.
Future Plans and Development Timeline
Rox is continuing its exploration program with multiple drill holes in progress across the project area. Results from these holes are expected in September, which could further expand the resource potential.
The company is also preparing its Definitive Feasibility Study (DFS) for the Youanmi project, incorporating the recent resource update and ongoing exploration success.
With a clear path to production and continued exploration success, Rox is positioning Youanmi to become Western Australia's next significant gold operation.
Investment Thesis: High-Grade, Growing Resource in a Tier-1 Mining Jurisdiction
Rox Resources presents a compelling investment case based on several key factors:
-
High-grade resource base: The current 2.2 million ounce resource at 5.6 g/t gold positions Youanmi among Australia's highest-grade emerging gold projects.

-
Multiple mineralisation styles: The discovery of semi-massive pyrite-hosted gold opens new exploration avenues across the project.
-
Regional potential: Success at the Currans prospect, 20km from the main resource, highlights the district-scale opportunity within Rox's tenement package.
-
Clear development pathway: With a resource update complete and DFS in progress, Rox is advancing rapidly toward production.
