SNX Launches 5,000m Drilling at As Safra Copper-Gold Project

Rapid Drilling Start Highlights SNX Operational Readiness

Sierra Nevada Gold (ASX:SNX) has demonstrated remarkable agility by beginning drilling at its As Safra Copper-Gold Project in Saudi Arabia mere hours after receiving exploration licences via Royal Decree. With three rigs; one reverse circulation and two diamond drilling; already turning, the company is executing a 5,000-metre Phase 1 program targeting a series of high-priority zones identified through an integrated approach combining geochemical, geological, and geophysical data.

The swift mobilisation underscores SNX’s strong in-country execution capability and positions it among the most advanced explorers following Saudi Arabia’s recent Round 9 licensing process. This operational momentum builds on the company’s earlier efforts, including the establishment of its Saudi subsidiary Arabian American Minerals, which facilitates local alignment and resource access as part of the broader strategy to capitalise on the Kingdom’s emerging mining sector under Vision 2030. SNX’s rapid transition from licence grant to drilling is detailed in its recent five exploration licences granted announcement.

District-Scale Mineralisation with Tier 1 System Characteristics

The As Safra project covers a 375 square kilometre area exhibiting a well-defined metal zonation pattern typical of large hydrothermal systems. This transitions from a central copper-gold core through broader silver-copper-lead and lead-zinc halos, suggesting significant scale and prospectivity. Initial drill targets are distributed across this extensive footprint, with many situated beneath shallow sand cover and untested historically, including anomalies coinciding with ancient mine workings and high-grade surface geochemistry.

SNX’s targeting integrates high-resolution ground magnetics, gravity surveys, and induced polarisation (IP) geophysics, the latter building on historic chargeability anomalies identified by BRGM surveys in the late 1960s. These geophysical signatures correlate with known copper mineralisation and ancient workings, bolstering confidence in the presence of sulphide-rich zones at depth. The ongoing IP program aims to refine these targets further, supporting real-time drill planning and prioritisation.

The company’s approach reflects a systematic vectoring strategy, utilising pathfinder elements such as bismuth and tellurium that often indicate proximity to high-temperature, metal-rich fluid pathways. This multi-disciplinary framework underpins the selection of initial Phase 1 drill sites and is expected to enhance discovery potential as drilling progresses. The integration of these datasets was previewed in SNX’s earlier magnetic survey at As Safra update.

Government Support and Strategic Positioning in Saudi Arabia

The project benefits from strong institutional backing by Saudi Arabia’s Ministry of Industry and Mineral Resources (MIMR) and the Saudi Geological Survey (SGS). These agencies have facilitated a modern and transparent licensing regime, streamlined permitting, and exploration incentives including reimbursement of up to US$2 million per licence. This supportive environment, combined with access to local contractors and workforce development, creates a favourable operational landscape for SNX.

As Safra’s strategic importance is amplified by its alignment with Saudi Arabia’s Vision 2030 economic diversification plan, which prioritises mining as a growth sector. SNX’s wholly owned subsidiary Arabian American Minerals ensures compliance with local regulatory frameworks and optimises exploration efficiency by leveraging regionally consistent datasets provided by SGS.

Looking Ahead: Drilling Timeline and Market Anticipation

The current drilling campaign is expected to span six weeks, with initial assay results anticipated by the end of May. SNX plans to maintain flexibility in its program, allowing for rapid reprioritisation and follow-up drilling in response to emerging mineralisation. The company will progressively update the market on drilling progress, target refinement, and assay outcomes, which will be critical in validating the exploration model and guiding subsequent phases.

Given the scale of the mineralised system and the robustness of the integrated targeting framework, early results could significantly influence the project’s trajectory. However, it remains to be seen whether these initial drill holes will confirm the high-grade feeder zones suggested by geophysics and surface sampling. The coming weeks will be pivotal in assessing As Safra’s potential to evolve into a major copper-gold discovery within a rapidly developing mining jurisdiction.
