Lanthanein Resources intersects primary gold mineralisation at Lady Grey

Lanthanein Resources Ltd has intersected primary gold mineralisation at its Lady Grey Project in the Yilgarn region of Western Australia. The high-grade results come from diamond drilling targeting a high-priority modelled moving loop electromagnetic (MLEM) conductor plate under Line #1, coinciding with a strong gold-in-soil anomaly (256 parts per billion gold) and a key structural corridor. Notably, hole LGDH004 returned 4.1 metres at 1.35 grams per tonne (g/t) gold from 134.66 metres, including 1 metre at 3.66 g/t gold.

The prospect lies adjacent to Covalent Lithium’s Mt Holland mine site, which hosts the historic Bounty Gold Mine that produced approximately 1.3 million ounces of gold. The encouraging results follow multiple delays due to bushfires and unseasonal rainfall but reaffirm the exploration potential of the Lady Grey Project.

“We are really very excited to finally have the highly anticipated assay results for the drill testing of the higher ranking modelled EM conductor plate under Line #1 which coincides with the 256 ppb Au UFF soil anomaly and the underexplored regional structural feature running up the middle of the tenement,” Lanthanein Technical Director Briant Thomas said.

“The fact we have hit primary gold mineralisation in the modelled conductor plate is extremely encouraging and testament to the hard work that the exploration team have put in at the Lady Grey Project over an extended period with significant delays with bushfires and then unseasonal rains at Mt Holland.”

Drilling program overview and targets

Lanthanein’s latest program tested two MLEM conductor plates at the Lady Grey Project, with holes LGDH001–003 targeting the conductor plate under Line #6 and LGDH004–005 focused on Line #1. 

The Line #1 conductor is aligned with a known surface gold anomaly and regional structural feature. 

Hole LGDH004 delivered a standout intercept of 4.1 metres at 1.35 g/t gold from 134.66 metres, including a higher-grade metre at 3.66 g/t gold. LGDH005 returned 1.27 metres at 0.55 g/t gold from 287.41 metres, with several lower-grade zones encountered at shallower depths.

Assay results and mineralisation characteristics

Gold mineralisation was confirmed in multiple samples from LGDH004 and LGDH005, with notable intersections including:

• LGDH004: 4.1m @ 1.35 g/t Au from 134.66m including 1m @ 3.66 g/t Au
• LGDH005: 1.27 metres at 0.55 g/t gold from 287.41 metres

Arsenic and silver were also observed, particularly in mineralised zones, indicating the presence of sulphide-associated gold. This aligns with the structural model for gold deposition along regional faults and deformation zones.

Geological setting and prospectivity

The Lady Grey Project sits within the Forrestania Greenstone Belt, known for gold, nickel and lithium mineralisation. The nearby Earl Grey pegmatite deposit and proximity to the historic Bounty Mine add geological and commercial significance. The modelled EM conductor plate tested under Line #1 correlates well with surface anomalies and confirms the structural model underpinning gold prospectivity in the area.

Next steps in exploration

With encouraging initial results, Lanthanein plans further drilling to test lateral and depth extensions of the gold zones. 

Future work will also include metallurgical and geotechnical studies to assess the potential for resource development. 

The company’s ongoing efforts aim to delineate a significant gold system at Lady Grey, supported by strong geological and geophysical indicators.
