Mt Ida - Ida Valley Project

Extensive uranium target identified on Mt Ida tenements

The Mt Ida-Ida Valley Project currently comprises 20 Exploration Licences and Exploration Licence Applications totalling over 2,210 sq km in area. The project area lies within the Eastern Goldfields region of the Archaean Yilgarn Block, which contains a stable nucleus of gneisses and granites and thin elongate greenstone occurrences. The granites and greenstone belts often contain layered successions of alternating mafic, ultramafic, felsic-clastic associations and pegmatite intrusives prospective for lithium, REE, precious and base metals.

Javelin announced in March 2024 it had identified an extensive uranium exploration target containing uranium mineralisation at the Stakeyard Well Uranium Prospect located within the central portion of the Mt Ida Project area in Western Australia.

Carnotite (radioactive, vanadium mineral that is an important source of uranium) was identified on the banks of E37/1490 within the Stakeyard Well Uranium Prospect, with limited exploration programs undertaken to date.
Continuous, strong uranium anomaly is hosted within E29/1134, E37/1490, E29/1237 and E37/1520, that extends across a 28km E-W distance by average 3.3km width, comprising of highly prospective Tertiary calcrete sediments over Lake Raeside.
Historical results from the shallow aircore drilling over Stakeyard Well include the below and the cut-off grade the Company applied in determining the assay results was 100 ppm uranium:
- Drillhole MWS0020: 1.5m @ 171.55 ppm U from 3.5m
- Drillhole MWS0026: 1.5m @ 297.64 ppm U from 3.5m
- Drillhole MWS0035: 1m @ 189.45 ppm U from 3.5m
- Drillhole MWS0034: 1m @ 118.71 ppm U from 4m
Uranium mineralisation is open to the south of the Stakeyard Well Uranium Prospect

Detail compilation and analysis of the historical data (geophysics, geochemical and drilling) has identified extensive strong radiometric anomaly over the Lake Raeside where historical aircore drilling returned significant uranium results over the Stakeyard Well Uranium Prospect which lies proximal to the Peninsula Uranium Deposit (see Figure 1).

Initial exploration by Esso Exploration/Production Australia Inc and Energy Metals Ltd from 2010 to 2014 identified a mineralised uranium mineralisation in shallow aircore drilling over the Peninsula Deposit and Stakeyard Well Uranium Prospect.

The Stakeyard Well prospect is located on the southern side of Lake Raeside where Granite Creek drains into a calcrete delta. Surface carnotite was identified on the banks of Granite Creek within E37/1490. Drilling (46 holes for 460 metres, on a 1,000-metre x 100 metre grid) through surficial cover revealed a profile of indurated quartz sand followed by calcrete, calcareous grits and clay. The programme was not able to drill the adjacent lake area because of surface water. Drilling has outlined two lenses of uranium mineralisation on either side of Granite Creek. Shallow uranium mineralisation was intersected during the drilling programme, usually above the water table at around 1.5 metre to 4 metres depth
