Maiden RC drilling confirms gold across Christmas Well’s key targets

CGN Resources (ASX: CGR) has returned gold mineralisation at three of four targets in its maiden reverse circulation (RC) drilling programme at the Christmas Well Project, near Leonora in Western Australia. The result is exactly what a proof-of-concept programme is designed to deliver: direct geological evidence that the targeted structures are fertile and capable of hosting meaningful gold mineralisation.

The programme comprised 15 RC holes for 2,093m across four prospects: Rocky Mountain Oyster, Sweetbread, Lambs Fry, and Ox Tongue. Gold was confirmed at Rocky Mountain Oyster, Sweetbread, and Lambs Fry. The standout intersection came from XRC0010 at Rocky Mountain Oyster: 5m @ 2.67 g/t Au from 151m, including 1m @ 10.45 g/t Au (as confirmed in Table 2 of the announcement — note the highlights page states 2.5 g/t Au and the body text states 10.94 g/t Au; Table 2 is the authoritative source and these figures are used throughout this article).

Christmas Well Maiden Drilling Scorecard

What the drill results revealed — target by target

Rocky Mountain Oyster — standout result validates structural model

Rocky Mountain Oyster (RMO) delivered the strongest result of the programme, confirming that gold mineralisation extends into fresh rock well beyond the reach of historical drilling. Hole XRC0010 extended the known mineralised system approximately 100m deeper and 80m along strike to the north from historical intersections, providing an important structural and geological vector for follow-up work. Mineralisation is hosted in a chlorite-altered shear zone with quartz veining within granite.

Key intersections (all figures from Table 2):

  • XRC0010: 5m @ 2.67 g/t Au from 151m (including 1m @ 10.45 g/t Au)
  • XRC0009: 7m @ 0.25 g/t Au from 57m
  • XRC0007: 4m @ 0.19 g/t Au from 83m

Lambs Fry — greenfield discovery adds new dimension

Lambs Fry is a largely greenfield structural target, and gold-bearing shearing was confirmed in both first-pass holes. The results are particularly encouraging given the target lies approximately 1.2km from the historical Jasper Flat open pit and sits adjacent to an area with historical small-scale workings, including a surface hit of 3m @ 7 g/t Au. Cross-section analysis suggests the gold intercepts may have a more flat-lying orientation, indicating an alternate drilling direction to the south will be required to better test the structure.

Key intersections (Table 2):

  • XRC0014: 8m @ 0.27 g/t Au from 19m and 1m @ 1.17 g/t Au from 15m
  • Mineralisation hosted within a shear zone containing quartz veining and minor pyrite within granodiorite

Sweetbread — gold confirmed, deeper cover complicates picture

Gold anomalism was confirmed at Sweetbread, but the programme could not adequately test the primary basement target. Unexpectedly deep transported cover, reaching approximately 120m in parts of the target area versus the expected 30–40m suggested by historical drilling, prevented thorough testing of the structural basement position. Hole XRC0012 was also terminated early at 84m due to water ingress and a thick zone of clay. The announcement notes that the depth of cover reduces the prospectivity of the target.

  • Multiple intersections above 200ppb Au recorded
  • Maximum assay of 0.58 g/t Au in XRC0012
  • Basement structural target not adequately tested in Phase 1
Hole ID Prospect From (m) Interval (m) Grade (g/t Au)
XRC0010 Rocky Mountain Oyster 151 5 2.67 (incl. 1m @ 10.45)
XRC0009 Rocky Mountain Oyster 57 7 0.25
XRC0007 Rocky Mountain Oyster 83 4 0.19
XRC0014 Lambs Fry 19 8 0.27
XRC0014 Lambs Fry 15 1 1.17
XRC0015 Lambs Fry 50 1 0.17
XRC0012 Sweetbread 76 2 0.38
XRC0013 Sweetbread 56 2 0.35

Understanding orogenic gold — why this geological model matters to investors

The term “orogenic gold” describes hydrothermal gold deposited along fault and shear zones during periods of crustal deformation. In plain terms, gold-bearing fluids travel through cracks and structures in the earth and deposit gold where conditions are right, typically where rock types change or structures intersect. This is one of the most economically significant gold deposit styles in the world, and the Leonora district has produced it in quantity.

CGN’s targeting strategy is focused on the contact between the Raeside Batholith (a large granitic intrusion) and the adjacent greenstone sequences of the Eastern Goldfields Superterrane. This boundary is geologically significant because northwest-trending structures channel gold-bearing fluids, making these contact zones highly prospective for orogenic mineralisation.

The nearby Kailis Mine provides a direct local analogue: gold mineralisation in the same structural setting, within the Raeside Batholith, already demonstrating that the geological model works in practice.

Historical shallow RAB (rotary air blast) and aircore drilling across the Christmas Well area largely failed to reach fresh basement rock, leaving structural targets systematically untested. CGN addressed this gap by integrating those historical results with a high-resolution aeromagnetic survey completed in late 2025, which identified the northwest-trending structures now being drill-tested. The maiden RC programme was the first serious test of these basement targets, and the results confirm the structures are gold-bearing.

What comes next — Panhandle drilling and follow-up targets

Two parallel workstreams are now underway. Follow-up drilling at Rocky Mountain Oyster and Lambs Fry is the immediate priority, with Panhandle Pelican moving towards its own maiden programme.

Planned next steps include:

  • Rocky Mountain Oyster: Define the geometry of the mineralised shear intersected in XRC0010; test along-strike and depth extensions
  • Lambs Fry: Test alternate drilling direction to the south to better intersect the interpreted flat-lying structure
  • Panhandle — Pelican prospect: Approximately 2,000m RC drilling programme planned for 2026; heritage approvals are in place, clearing the path to first-pass drilling
  • Ox Tongue: Further reinterpretation of high-resolution magnetic data before any additional drilling decision is made
  • Christmas Well tenure: All tenements now granted, providing full access across the broader project area

Managing Director, Stan Wholley

“To deliver positive results from our maiden drilling program at Christmas Well is an excellent outcome for CGN and a strong endorsement of the work undertaken by our technical team. More importantly, we set out to test a geological concept. Our team compiled the historical information, acquired new datasets and developed a targeting strategy focused on structures extending from the greenstones into the surrounding granites of the Raeside Batholith. This first drilling program has now intersected gold at three of the four principal target areas tested.

That is an important result. This was a proof-of-concept program, and it has demonstrated that the structures we are targeting are fertile and capable of hosting meaningful gold mineralisation. We now have the geological evidence and confidence to follow these structures, expand the mineralised footprints and progressively work towards defining larger zones of gold mineralisation.

With Christmas Well now delivering encouraging maiden drilling results and Panhandle moving towards drilling, CGN is entering an exciting phase of systematic exploration across what we believe is an increasingly compelling gold portfolio in the Leonora district.”

Investment case — proof of concept delivered

CGN has moved Christmas Well from a series of conceptual targets to a geology-proven exploration portfolio with clear follow-up vectors. Three out of four targets returning gold in a maiden programme is a strong hit rate for first-pass RC drilling.

Key takeaways from the programme:

  • Maiden programme: 3 of 4 targets returned gold mineralisation, validating the structural targeting model
  • High-grade intercept in fresh rock at RMO opens depth potential well beyond the limits of historical drilling
  • Lambs Fry greenfield discovery adds a new mineralised corridor to the portfolio
  • Systematic follow-up drilling is now planned across two active project areas: Christmas Well and Panhandle
  • Growing land position in the Leonora district, a proven gold province that includes Sons of Gwalia (more than 8Moz) nearby

The drill results provide the geological confidence and technical vectors to move into a more targeted phase of exploration. The immediate task is converting these early intersections into a better understanding of structural geometry and identifying the positions most capable of hosting thicker, higher-grade mineralisation.

Frequently Asked Questions

What is reverse circulation (RC) drilling and why does it matter for gold exploration?

Reverse circulation drilling uses compressed air to return rock chips to the surface through the drill rods, allowing geologists to sample fresh, uncontaminated rock at depth — making it far more reliable than shallow RAB or aircore methods for testing basement gold targets.

What did CGN Resources find in its maiden drilling at Christmas Well?

CGN confirmed gold mineralisation at three of four targets tested across 15 RC holes for 2,093m, with the standout result being 5m @ 2.67 g/t Au from 151m at Rocky Mountain Oyster, including 1m @ 10.45 g/t Au, extending the known system 100m deeper than historical drilling.

Where is the Christmas Well Project located and why is the Leonora district significant for gold?

Christmas Well is located near Leonora in Western Australia's Eastern Goldfields, a district that includes the Sons of Gwalia deposit at more than 8 million ounces — one of Australia's most significant historical gold mines — making it a proven gold-producing province.

What is orogenic gold and why is CGN targeting it at Christmas Well?

Orogenic gold forms when hydrothermal fluids deposit gold along fault and shear zones during crustal deformation — one of the world's most economically significant gold deposit styles. CGN is targeting the contact between the Raeside Batholith and adjacent greenstone sequences, a structural setting already demonstrated to host gold at the nearby Kailis Mine.

What are CGN Resources' next steps after the Christmas Well drilling results?

CGN plans follow-up drilling at Rocky Mountain Oyster to test strike and depth extensions, a revised drilling direction at Lambs Fry to better intersect the interpreted flat-lying structure, and a separate ~2,000m RC programme at the Panhandle — Pelican prospect in 2026, with heritage approvals already secured.
