THE DRILL SERGEANT: Marindi Metals (ASX: MZN) provided an update on exploration activities at the company’s Forrestania lithium project.
Marindi Metals has completed ground work to follow up soil sampling, which identified two highly prospective pegmatites showing similarities to the Earl Grey pegmatite, located 60 kilometres and 80 kilometres north of the respective prospective areas.
Infill soil sampling results led to a field inspection of anomalous areas undertaken at the Cosmic Boy East and Diggers Rocks East target areas.
At Cosmic Boy East, an area of highly anomalous tantalum in soil with peak values to 6.5ppm tantalum pentoxide (Ta2O5) was inspected.
Within the soil anomaly a poorly exposed pegmatite was identified and sampled, which returned assays that indicated it to be a highly specialised LCT pegmatite assaying 157.5ppm Ta2O5 with both potassium/rubidium (K/Rb) and potassium/caesium (K/Cs) ratios.
Marindi claimed this to be broadly comparable with data published on the nearby Earl Grey pegmatite.
At Digger Rocks East, Marindi inspected an area of highly anomalous caesium where peak values to 11.5ppm caesium in soils had been returned.
This identified a further poorly exposed pegmatite to be sampled, returning assays indicated it to be another highly specialised LCT pegmatite assaying 36.8ppm Ta2O5 and 12.8ppm Ta2O5 in separate samples.
Once again, Marindi claimed both the potassium/rubidium and potassium/caesium ratios to be consistent with data published on the nearby Earl Grey pegmatite.
“Drilling will be required to determine the size and mineralogy of these pegmatites,” Marindi Metals said in its ASX announcement.
“The fact that soil sampling has led to the identification of outcropping specialised pegmatite is considered encouraging and a validation of the exploration technique as a first pass filter to discriminate prospective from less prospective ground in areas of residual soil or shallow cover.
“Infill soil sampling is ongoing and follow up inspections will continue as more anomalous areas are identified and Marindi expects to have results from the infill samples next week.
“Marindi has already begun plans for an initial drill program and will finalise its drilling program once these assays are received.”
