THE DRILL SERGEANT: Predictive Discovery (ASX: PDI) announced encouraging results from initial soil sampling at the company’s 100 per cent-owned Nonta roject in Guinea.
Predictive Discovery identified the Nonta project area after carrying out a terrain-scale assessment of the Siguiri Basin in late 2018 using the company’s trademarked Predictore gold targeting system.
Predictive collected a total of 446 soil samples with peak values of 1250ppb and 325ppb gold in two separate zones.
The first, a plus five-kilometre-long anomalous zone (mostly 20-50ppb gold) oriented north-south with a peak value of 1250ppb gold (1.25 g/t gold).
The second, a north-north-west oriented 400m-long zone, open to the north, with numerous elevated values (>50ppb gold) and a peak value of 325 ppb gold.
Predictive said these were coincident with the Nonta prospect, from which earlier rock chip sampling obtained up to 29g/t gold.
Most of the samples were collected on a broad spaced (800m x 100m) grid covering plus 20ppb gold stream catchments identified from a previously completed Bulk Leach Extractable Gold (BLEG) geochemical survey.
A closer spaced grid (100m x 25m) was subsequently completed over the Nonta prospect.
The survey indicated some complexity in the regolith (i.e. surface materials: soil, laterite etc).
Predictive explained it is currently investigating gold distribution in the weathered profile by mapping and profile sampling and plans to start infill soil or power auger sampling in September-October once this work is complete.
“These new results confirm the Nonta project’s gold prospectivity,” Predictive Discovery managing director Paul Roberts said in the company’s announcement to the Australian Securities Exchange.
“Values of up to 29 grams per tonne gold in rock chip samples and up to 1.25 grams per tonne gold in soils indicate potential for economically valuable gold mineralisation.
“Over the next few months, we will focus on understanding the complex regolith at Nonta and infill sampling to vector in on targets for a possible RC drill campaign in late 2019 or early 2020.
“We are excited by the exploration potential of the Siguiri Basin and specifically of our Nonta, Kankan and Kaninko projects.
“We have been welcomed warmly by the Guinea’s Mining Ministry, which has helped us greatly in acquiring this high potential ground so quickly.”
