Sierra Nevada Gold Strikes High-Grade Copper-Gold at As Safra Project in Saudi Arabia
Sierra Nevada Gold Limited (ASX: SNX) has delivered impressive new exploration results from its As Safra Copper-Gold Project in Saudi Arabia, with rock chip sampling returning exceptional grades of up to 9.66% copper and 12.6g/t gold. These results not only confirm historic high-grade findings but also provide the geological framework needed to launch a targeted drilling campaign as early as late March 2026.
The recent sampling programme has successfully identified three priority copper-gold target corridors within a substantial 5.5-kilometre mineralised trend. Furthermore, this positioning establishes SNX to advance one of the most promising Sierra Nevada Gold As Safra copper-gold projects in the Middle East region.

High-Grade Surface Results Confirm System Strength
SNX's systematic rock chip sampling across the Sierra Nevada Gold As Safra copper-gold project area has validated the exceptional mineral endowment first identified by the French Geological Survey (BRGM) decades ago. According to the announcement, the programme returned multiple standout results that demonstrate the consistency and grade potential of surface mineralisation.
Key Sampling Highlights:
• 9.66% Cu and 9.13g/t Au from northern target area
• 9.31g/t Au and 6.59% Cu from cross-cutting veinlets
• 12.6g/t Au and 4.54% Cu from foliated copper oxides
• 6.36g/t Au and 1.02% Cu from iron gossans
The sampling also revealed crucial pathfinder elements that provide vectors to high-grade mineralisation at depth. For instance, bismuth values reached up to 898ppm whilst tellurium concentrations achieved 410ppm.
These bismuth-tellurium-copper associations are critical indicators in skarn environments. They uniquely fingerprint the hot, focused metal-bearing fluid pathways that feed high-grade copper-gold systems.
Management Commentary:
"Results from the recent sampling programme are highly encouraging and confirm the strength and scale of the As Safra mineral system. The identification of multiple copper–gold target corridors within a 5.5-kilometre mineralised trend highlights the district-scale potential of As Safra and provides a clear pathway into drilling." – Peter Moore, Executive Director
Understanding Geochemical Vector Analysis: The Key to Targeting Success
What is Bi-Te-Cu Vector Analysis?
Bismuth-tellurium-copper (Bi-Te-Cu) geochemical vectoring represents one of the most sophisticated targeting methods for copper-gold skarn systems. This technique identifies focused, high-temperature fluid pathways within mineralised systems by analysing the spatial distribution of these three key elements.
Why This Matters for Investors
In skarn-style copper-gold deposits, bismuth indicates system fertility (the overall mineral-forming potential). Moreover, tellurium shows proximity to gold-bearing fluids and breccias, while copper traces the primary fluid pathways.
When these three elements occur together in elevated concentrations, they provide a robust method for targeting the mineralised cores. These cores typically host the highest-grade copper-gold mineralisation.
For the Sierra Nevada Gold As Safra copper-gold project, the identification of strong Bi-Te-Cu associations has successfully defined three priority target corridors. These areas demonstrate the strongest and most coherent geochemical responses – exactly where investors want to see the first drill holes targeted.
Historic Drilling Validates Depth Potential
A comprehensive review of historic drilling conducted by the BRGM in the late 1960s provides compelling evidence for mineralisation continuity at depth. According to available records, all seven historic drill holes intersected primary copper sulphide mineralisation beneath the surface oxide zone.
| Drill Hole | Interval | Grade | Comments |
|---|---|---|---|
| SE 1 | 24.55m @ 1.69% Cu | Plus 0.13% Zn, 3.5g/t Ag | Longest significant intercept |
| SE 1 | 5.0m @ 4.07% Cu | High-grade core zone | Primary sulphides |
| SE 4 | 6.0m @ 1.08% Cu | Plus 0.22% Zn | Consistent mineralisation |
| SE 5 | 4.7m @ 1.76% Cu | Plus 0.1% Zn, 11g/t Ag | Multi-metal potential |
Importantly, the locations of these historic high-grade intersections correspond directly with areas now identified as priority targets through modern geochemical interpretation. This provides independent validation of SNX's current geological model.
Drilling Campaign Set to Commence
With exploration licences expected to be granted in Q1 2026, SNX has positioned itself for immediate drilling mobilisation. According to the company, it has already achieved significant operational readiness milestones.
Operational Readiness:
• Selected drilling contractor with rigs secured
• Planned up to 5,000 metres of combined RC and diamond drilling
• Targeted drilling commencement by late March 2026
• Planned expansion of IP geophysical surveys using modern equipment
• Commissioned detailed ground magnetic surveys for refined targeting
The systematic approach combines modern geochemical vectoring with historic drilling validation to significantly reduce exploration risk. This represents a crucial advantage for investors as SNX transitions from surface exploration to subsurface discovery.
Why As Safra Represents a Compelling Investment Opportunity
District-Scale Mineral System
The Sierra Nevada Gold As Safra copper-gold project exhibits characteristics of a large-scale mineralised district with well-developed metal zonation. The project transitions from a central copper-gold core into broader silver-copper-lead and lead-zinc-silver distal systems across 375 square kilometres.
This zonation pattern is typical of major mineral districts worldwide. Furthermore, it suggests significant discovery potential beyond the current focus areas.
Strategic Location Advantages
The project benefits from excellent infrastructure including:
• Paved road access to target areas
• Proximity to Saudi Arabia's industrial centres
• Government support for mining development
• Established regulatory framework for exploration
Multiple Discovery Vectors
Historic IP surveys reveal numerous untested chargeability anomalies interpreted as potential sulphide bodies at depth. Additionally, thin sand cover across large portions of the project creates opportunities for blind discoveries.
These represent mineralised zones not exposed at surface that could constitute entirely new ore bodies. Consequently, this significantly expands the exploration potential beyond visible surface expressions.
Proven Management Track Record
SNX's technical team brings extensive experience in copper-gold exploration. They have demonstrated the ability to integrate historic data with modern techniques to reduce exploration risk and improve targeting efficiency.
Investment Thesis: Positioned for Near-Term Catalysts
Sierra Nevada Gold has transformed As Safra from a collection of historic prospects into a systematically targeted, drill-ready copper-gold project. The combination of high-grade surface mineralisation, validated depth continuity through historic drilling, and sophisticated modern targeting provides multiple pathways to discovery success.
Key Investment Drivers:
• Immediate catalyst timing with drilling planned for late March 2026
• High-grade surface results confirming exceptional system fertility
• Validated depth potential through historic intercepts up to 24.55m @ 1.69% Cu
• District-scale opportunity across 375km² of prospective ground
• Reduced exploration risk through integrated geochemical and historic data analysis
However, investors should recognise that exploration programmes carry inherent risks. Success cannot be guaranteed despite strong technical foundations and systematic targeting approaches.
