TNT Mines Ltd (ASX:TIN) has identified five high-priority targets for discovery follow-up drilling from a GAIP (ground array induced polarisation) study at the Reids Ridge Project northeast of Paynes Find in Western Australia.
The GAIP surveying, which was completed in July, has been undertaken by KHUMSUP Geophysics under the management of Perth-based Resource Potentials and covered the entire strike length of the intrusive body within the M59/755 tenement at Reids North.
TNT believes the GAIP data received to date is of excellent quality and data interpretation remains ongoing at this time.
One zone of high chargeability directly overlies with the position of the recently drilled RRRC0011 RC hole which intersected 44 metres at 1.12 g/t gold in the northwest corner of the M59/755 tenement block.
Survey results are “significant”
Speaking to the results, chairman Alex Hewlett said: “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 2.5-kilometre strike length that has yet to be drilled and represents an excellent target with bulk tonnage gold potential”.
A total of eight target sites
The strong chargeability response coincident with the RRRC0011 location extends around 500 metres 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 eight targets sites have been identified by Resource Potentials, with four lines of Pole Dipole IP designed to test the highest priority targets.
The follow-up IP program is scheduled to kick off in mid-August.
"Large widths give confidence"
TNT chief executive officer Matthew Boyes said: “The results of the GAIP survey showing strong anomalism coincident with areas, which we have demonstrated to contain large widths of gold mineralisation give us confidence this intrusive hosted system could host mineralisation over an extensive area.
“We look forward now to getting the follow up pole-dipole study completed to aid with our targeting of the next round of drilling.”
Looking ahead
Two historical drill holes in 2019 (WRC 1908 and 1909) by a previous owner returned shallow low-grade gold grade mineralisation.
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.
PDIP survey planned for August
The PDIP program 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.
Targets have been prioritised based upon the criteria in the following table with follow up drilling and DD-IP prioritised in the zone close to RRRC0011.
