Key Highlights

  • Grab samples from historical mine dumps returned silver of up to 1,509 g/t.
  • Other results include copper up to 1.62%, lead up to 6.33%, indium of 13.9 g/t and antimony of 16.41%.
  • The large Liver Peak porphyry system lies about 2 km northwest of the Raven project area.
  • Olympio is assessing whether historical veins could be linked to a deeper hydrothermal system.

Olympio Metals Limited (ASX:OLY) has reported high-grade critical mineral results from reconnaissance grab samples at its Raven Project in Montana, USA, in an announcement dated 4 November 2026. The samples were taken from historical mine dumps at the Raven and Silver King workings.

Sample Results Across Several Metals

Silver reached 1,509 g/t in sample SK-26-002. Sample SK-26-003 returned 1.62% copper, 6.33% lead and 1.33% zinc. Indium reached 13.9 g/t in sample SK-26-001, while antimony reached 16.41% in RN-26-001 and tungsten reached 1,037.2 ppm in RN-26-002.

The company notes that silver, copper, lead, zinc, antimony, indium and tungsten are all included on the 2025 US Critical Minerals List, which places the results within a category of commodities the US government has identified as critical.

The results are reported as individual sample values rather than intervals, which indicates that metals are present in the sampled material but not how they are distributed across a deposit. The company notes that the samples are not representative of in-situ grades, so the figures should be read as an indication of mineral presence.

Liver Peak Porphyry Context

A large known porphyry system called Liver Peak lies about 2 kilometres northwest of the Raven project area. Historical reports describe Liver Peak as associated with a magnetic high and a quartz-eye porphyry system along the regional structural trend that passes through Raven.

Regional gravity data show a broad low in the vicinity of the Liver Peak area, which the company is considering as part of its targeting.

The regional gravity low near Liver Peak is one of the features Olympio is considering in its targeting. The historical reports and gravity data together form the basis for linking the Raven veins to a deeper system, although the company has not yet confirmed that link through drilling.

Next Phase of Assessment

Olympio is assessing whether the historical Raven, Silver King and Copper King veins could be connected to a deeper hydrothermal system with porphyry potential. The company is working toward a maiden drill program as that assessment progresses.

The announcement indicates that the historical veins were mined for silver, copper, lead and zinc, which informs the current targeting.

The maiden drill program is the next stage of the company's work, and the release does not give a date or budget for it. The assessment of whether the Raven and Silver King veins connect to a deeper system will determine the scope of that program.

Sampling Context and Limitations

Grab samples are selective by design and are taken from places where mineralised material is visible. The company notes that the samples come from historical mine dumps, so the material has already been moved and may not reflect the original vein geometry. The results are therefore best understood as an indicator of the metals present in the historic workings. The company's next phase, including the maiden drill program, will provide information on the continuity and grade of the veins at depth.

Final Word

The results come from historically mined material, which the company itself notes is not representative of in-situ grades or the distribution of mineralisation. The data helps guide targeting, but the samples do not establish the scale or grade of any mineralisation at Raven. A maiden drill program will be needed to test whether the veins extend to depth.
