About the Company

Orpheus Uranium Limited is an ASX-listed exploration company based at 79 King William Road, Unley, South Australia. It explores for uranium in South Australia and the Northern Territory, both jurisdictions that allow uranium exploration, Mining and processing.

The company has also extended its tenure into Western Australia through a sale agreement for the Oobagooma Uranium Project, which it says is progressing to completion. Clinton Dubieniecki is Managing Director and Company Secretary, and Richard Willson is Chief Executive Officer.

Business Overview

Orpheus focuses on sedimentary-style, sandstone-hosted uranium. The Frome Project sits within the Callabonna Sub-Basin and the underlying Frome Embayment in South Australia, and remains in the Advanced Exploration category of the company's project pipeline. The company describes Frome as complementing its other South Australian sedimentary-style uranium assets.

Exploration at Frome targets redox transitions in the Tertiary Eyre Formation, with potential to extend assessment into the overlying Namba Formation and underlying Cretaceous sediments. The company compares the footprints of its target areas with deposits in the same basin, including Heathgate's Four Mile projects and Boss Energy's Honeymoon and Gould's Dam projects. Managing Director Clinton Dubieniecki said the work used historical data to develop and test geological models.

Inaugural Drilling at Erudina

In its announcement dated 22 October 2026, Orpheus said it had completed its first drilling program at the Erudina Uranium Prospect, comprising 18 rotary mud holes totalling 3,600 metres. Downhole geophysical logging was completed in 16 holes. Of those, nine recorded peak results above 100 ppm eU3O8, including two above 400 ppm, while six targeted oxidised sand packages where depleted uranium grades were expected.

Collar locations and results are tabulated in the appendices, and the company said geological observations were largely consistent with its interpretation. It described the campaign as the first drilling in the area in about 15 years. An initial weather event interrupted the program, and additional work was needed to source water and mobilise the drilling team from interstate.

Siccus Redox Corridors Defined

The announcement said the program refined four target areas within Erudina, now named Siccus North, Siccus East, Siccus South and Siccus West. Siccus East and Siccus West are two north-south-trending corridors extending at least 2.2 kilometres along strike, marked by redox changes within the Eyre Formation.

At Siccus East, the interpreted priority corridor extends about 2.2 kilometres and is up to 250 metres wide. Orpheus stressed that these dimensions describe the area selected for investigation rather than a demonstrated mineralised body. Siccus North is a potential northern continuation, while Siccus South is an early-stage concept testing a deeper unit of possible Cretaceous age, whose identity and uranium potential remain unresolved.

Related Sector Context

Uranium exploration in South Australia's Callabonna Sub-Basin focuses on roll-front style deposits, where uranium carried in oxidised groundwater can be deposited on meeting reducing conditions. Such fronts can be narrow and sinuous, and the company noted that not all redox boundaries are mineralised.

In the 22 October 2026 session the S&P/ASX 200 and All Ordinaries were both lower at 11:55 am, while Orpheus shares were trading higher.

Risks to Weigh In

Orpheus states that intersecting significant uranium mineralisation remains an objective rather than an achieved outcome. The interpretations rest partly on historical exploration data, which the company cautions may have incomplete records and variable quality compared with modern methods.

Any Exploration Target depends on further drilling and, if results warrant, a JORC-compliant resource. The company said the timing of future drilling programs is yet to be determined in the context of its broader uranium portfolio, and the program itself faced weather and water Supply constraints.

Catalysts on Watch

Orpheus said the next phase will integrate and validate the available data, rank the four Siccus areas and develop follow-up drilling programs to test the relationship between redox boundaries and mineralisation. Further interpretation is under way at Siccus North and Siccus South, including assessment of radiometric responses and drilling gaps. Timing of future drilling is yet to be set, and the company said it may apply the learnings across its other uranium projects.

Putting It Together

Orpheus Uranium shares rose during the 22 October 2026 session while the benchmarks eased. The company's announcement of the same date sets out an 18-hole program, four defined Siccus target areas and a follow-up plan whose timing is yet to be confirmed.
