Predictive Discovery (ASX: PDI) has extended the known gold mineralisation system at the Laterite Hill Grid, part of the Bonsiega Project in Burkina Faso.
Assays from power auger sampling have identified a new 2.2 kilometre long weathered bedrock gold anomaly at Laterite Hill, extending the aggregate strike length of gold mineralisation to more than 18 kilometres, open to the north and west.
Peak values from the assays included 5.7 grams per tonne (g/t) gold, 2.7g/t gold, 2.1g/t gold and 1.4g/t gold, on a 400 metre by 50 metre power auger drill grid.
These results coincide with a significant geological structure that was interpreted from aeromagnetic data.
A four hole reverse circulation drilling program will begin in the next one to two weeks to test the structure.
Managing director Paul Roberts said the results were highly encouraging in an area with shallow cover.
“Obtaining a series of plus 1g/t Au power auger results on wide spaced geochemical drilling is quite unusual and may well represent significant gold mineralisation. PDI is moving immediately to test two of the higher grade targets with RC drilling,” Roberts said.
A total of eight prospects have now been defined in the Bonsiega Laterite Hill Grid area, while a second possible structure has also been identified, with a peak value of 3.5g/t gold.
Further diamond, reverse circulation and auger drill assays are expected in the next three weeks.
“The potential for delineating a large gold resource on the Bonsiega Project continues to grow,” Roberts said.
