HISTORICAL DRILLING
Multiple significant rock chip samples of up to 37.6% Mn
Geological mapping and additional rock chip sampling along with further drilling along strike
Project
Hill 616
- 35km south of Oakover
- Shallow gently dipping geology, similar to Oakover
- Historical drilling of more than 4,900m over a strike of 2.2 km
- 57.5 Mt @12.2% Mn Inferred Mineral Resource
Exploration licence E52/3633 forms the Hill 616 Project covering 5 blocks or approximately 15.7 km2 of the established mineralogical terrain of in the South-eastern Pilbara Mining District and is located approximately 85km south-east of Newman within the Peak Hill Mineral Field.
The Hill 616 Project has undergone extensive RC drilling, with 112 holes completed for 3,727 metres. The drilling was conducted over a wide–spaced (100m × 200m) grid pattern. Significant widths of manganiferous mineralisation were intersected over the entire 2.6 km’s of strike covered by the drilling program.
High grade (>20% Mn) manganese mineralisation was encountered in several small zones, both in the central and southern part of the prospect area. It was found that these high-grade zones have been delineated in drilling from areas with no significant surface expression of manganese, therefore potential remains to find further high-grade mineralisation to the south of the prospect. The high-grade mineralisation occurs as massive, brecciated, dull to bright manganiferous material hosted in completely oxidised clay zones.
Previously 5,000m of drilling completed across a strike length of 2.6km. Significant results include:
13m @ 15.07% Mn from surface; 12m @ 15.90% Mn from 4m; 12m @ 15.18% Mn from 3 m; 10m @ 15.76% Mn from 2 m; 9m @ 16.15% Mn from 5 m; 4m @ 25.56% Mn from 6 m; inc. 1m @ 31.76% Mn
Manganese zone intersected at both the North-West and South-East extents of the previous drilling program, indicating the mineralisation is open along strike in both directions
The manganese mineralisation occurs as multiple seams or bands of varying thickness within a highly weathered shale (Balfour Formation). Significant zones of manganese were still being intersected at both the North-West and South-East extents of the drilling program, indicating that mineralisation is open along strike in both directions.
The previous drilling at the Hill 616 Project suggests that the mineralisation at the Hill 616 Project is generally shallow (mostly within 20 metres of the surface), gently dipping and laterally extensive across the target area. Significant widths of manganiferous mineralisation were intersected over the entire 2.6 km’s of strike covered by the previous drilling program.
