Pantoro Ltd (ASX:PNR)’s maiden step-out drill program on the prospective Lamboo ultramafic basal contact at its 100%-owned Halls Creek Project in WA, has returned platinum group element (PGE) results described as "outstanding".
New drilling has defined a further 1.2 kilometres of PGE mineralisation on the basal contact of the West Limb and Southern Ore Zone with a best result of 100 metres at 1.10 g/t platinum+palladium+gold (3E) from surface including 66 metres at 1.34 g/t from surface.
All the areas drilled to date remain open in all directions.
More than 1.5 kilometres in total mineralised strike have now been drilled and defined out of a potential 20 kilometres basal contact target.
A wide consistent mineralised PGE zone has been defined from surface to over 150 metres vertical and remains open.
“Outstanding” discovery
Pantoro managing director Paul Cmrlec said: “The Lamboo PGE deposit is rapidly shaping up as an outstanding discovery on the doorstep of our Halls Creek gold operations.
“Drilling to date has revealed a remarkably consistent deposit with large mineralisation widths commencing from surface over a long strike length.
“Pantoro will advance mapping and surface sampling of the deposit throughout the wet season ahead of a large drilling campaign planned to commence as soon as seasonal weather conditions allow good access.”
Drill results
New results, which include a significant palladium component, also include:
- 120 metres at 0.96 g/t from surface including 31 metres at 1.24 g/t from 89 metres;
- 118 metres at 0.90 g/t from surface including 46 metres at 0.98 g/t from 10 metres;
- 46 metres at 1.11 g/t from surface;
- 22 metres at 1.11 g/t from surface;
- 31 metres at 0.90 g/t from 36 metres;
- 37 metres at 0.90 g/t from 14 metres;
- 71 metres at 0.59 g/t from 120 metres; and
- 90 metres at 0.69 g/t from surface including 24 metres at 0.99 g/t from surface.
Lamboo PGE Deposit
The basal portions are interpreted to be a pyroxenite and are unusually enriched in PGE and nickel, with the broad intercepts indicating the potential for large, bulk tonnage styles of platinum+palladium+gold mineralisation.
Pantoro’s drilling was initially focused on the Edison prospect, however, the latest program has been successful in stepping out to evaluate the basal contact of the Western Limb and Southern Ore Zone.
Mineralisation is noted to be consistent over large drill intervals commencing from surface and mineralisation widths of up to 100 metres have been encountered to date.
Pantoro considers that there is strong potential for a large, bulk-tonnage PGE resource to be defined in the near term.
Further work
Pantoro plans to undertake on-ground contact mapping and sampling over the wet season in preparation for a large step-out drill program designed to test an additional 10 kilometres of strike immediately after the end of the wet season in early 2022.
