John Galt Project
Project Overview
The John Galt Project comprises four 100% owned tenements which cover a combined area of 78km². The project area is situated in the East Kimberley region of Western Australia, approximately 200km south of Kununurra and 35km from the Great Northern Highway.
Overview
- Northern Minerals metallurgical test work on Main Zone mineralised breccia samples are highly encouraging, with recoveries up to 94% with a TREO concentrate grade of 47% and 56% for the two samples1
- Several programs of geological mapping, soil and rock chip sampling, and portable XRF surveys have been completed by Northern Minerals since 2011
- Rock chips show exceptional grades of up to 42% TREO including 3.68% dysprosium2
- Main Zone sampling returned an average uncut grade of 1.47% TREO. The average uncut grade of 12 channel samples taken from the base of the ridge at the Main Zone was 5.53% TREO.
- Northern Minerals plans to complete a diamond drilling program at the Main Zone
- Copper anomalies identified to be followed up, with potential for commodity diversification to meet the global energy transition requirements3
- Work program of detailed mapping, geochemical sampling and RC scout drilling to be undertaken

Historic Exploration
Heavy Rare Earth (HRE) mineralisation was discovered by
previous explorers at the John Galt Project in 1971 following an
airborne radiometric survey. On-ground follow up work,
identified hydrothermal xenotime mineralisation at three
different zones (including the Main Zone). Historical rock chip
sampling from the mineralised zones returned assays up to
53.5% TREO.
In 1973, the Main Zone was partially tested with nine diamond holes (for a total of 503m) with significant historic drilling results as follows:
- 2.05m at 5.98% TREO from 6.50m in DH1
- 3.90m at 6.30% TREO from 9.10m in DH2
- 3.48m at 3.48% TREO from 102.60m in DH8
- 9.80m at 1.58% TREO from 6.35m in DH9
The presence of mineralised xenotime veins at the base of the cliff beneath the John Galt Main Zone, together with the deeper drill intercept in DH8 (102.6m), indicate the potential extension of mineralisation below the cliff / scree contact. No further drilling has been carried out on the project since the 1973 drilling program.
