GAIP Survey Sights Overall Strike Length Of 2.5km
TNT Mines Ltd (ASX: TIN) has received strong results from a GAIP (Ground Array Induced Polarisation) study recently completed at its Reids Ridge project 50km north east of Payne’s Find in Western Australia.
Chairman Alex Hewlett commented on these results,“The findings of this survey are significant to TNT as they support a correlation of high chargeability with the excellent drill intersection seen in hole RRRC0011. Taking this one step further the survey has been able to define a large area displaying a similar chargeability response over a 2.5km strike length that has yet to be drilled and represents an excellent target with bulk tonnage gold potential”.
Ground Array Anomaly
Gradient array induced polarisation (GAIP) surveying at the Reids Ridge-Commodore project was completed during July 2021 following up on the recent drilling success at Reids North. The survey was carried out by KHUMSUP Geophysics under the management of Perth based Resource Potentials and covered the entire strike length of the intrusive body with the M59/755 tenement. GAIP data received is of excellent quality and data interpretation remains ongoing at this time. Preliminary high-level review of the data indicates that GAIP chargeability and resistivity anomalism generally follows the interpreted NNE-SSW strike of the Warriedar fault, with zones of elevated chargeability and resistivity proximal to interpreted splay faults located on the northwest side of the Warriedar fault zone.
One zone of high chargeability directly overlies with the position of the recently drilled RRRC0011 RC hole which intersected 44m @ 1.12g/t gold (see release dated 22/06/21) in the northwest corner of the M59/755 tenement block. The gold mineralisation is hosted within sulphide bearing veinlets developed within a large felsic intrusive body striking sub parallel to the interpreted position of the Warriedar fault. The strong chargeability response coincident with the RRRC0011 location extends approximately 500m in strike north and south of the drilled location making this area a priority follow up target for the next round of drill testing.
Strong chargeability and coincident resistivity are also shown in the survey directly west of the Commodore mine and Reids Ridge mine localities with very limited drill testing completed in these areas to date. A total of 8 targets sites have now been identified by Resource Potentials with 4 lines of Pole Dipole IP designed to test the highest priority targets. The follow up IP programme is scheduled to commence in mid-August.
Two historical drill holes in 2019 (WRC 1908 and 1909) by a previous owner returned shallow low-grade gold grade mineralisation as seen in figure 1. These results are now interpreted by TNT to confirm the continuity of this chargeability anomaly, however they appear to be too shallow and too far west of the Warriedar fault to have intersected the interpreted higher grade contact zone as seen in hole RRRC0011.
Resource Potentials has put forward a preliminary design of a dipole-pole IP (PDIP) survey lines to better understand and profile in section the position of the bodies giving the strongest chargeability and resistivity anomalies. These profiles will be utilised to design the next round of drill testing at the Reids Ridge north intrusive target and the chargeability anomaly west of Reids Ridge mine. The PDIP programme is tentatively scheduled to commence in mid-August although timelines may change due to the current lockdown in South Australia where the IP crew is based. Drill design will be completed immediately upon receiving the IP profiles.
