TNT is targeting depth extensions of Reids Ridge gold mine
TNT Mines (ASX:TIN) is preparing to start drilling targeting the interpreted down-dip extension of known mineralisation at the base of the historical Reids Ridge mine.
The planned drilling program of work at the Reids Ridge gold prospect – part of its Warriedar project northwest of Paynes Find in Western Australia – will begin once a rig is secured, which is expected in early April.
Assays are also pending for the majority of holes from its recently completed Phase 1 drill program at its Eureka project.
Results from the first 26 holes from the 89-hole program had delivered high-grade results such as 3m grading 7.89 grams per tonne (g/t) gold within a broader zone of 34m at 1.75g/t gold from a depth of 103m.
The company will start geological modelling and interpretation once the results are received and planning for Phase 2 drilling at Eureka will begin once the Reids Ridge drill program is completed.
Warriedar covers a region in the south of the Warriedar Fold Belt that is prospective for banded iron formation (BIF)-hosted gold as well as for gold hosted in narrow quartz vein-bearing structures that trend northeast throughout the area.
Initial drilling is designed to intersect the interpreted down-dip extension of the known mineralisation at the base of the existing Reids Ridge mine, where to date very little exploration below 150m from surface has been carried out.
Mineralisation at Reids Range is hosted in a northeast-southwest trending sub-vertical fault structure and associated with intense silicification and sulphidation up to 2.5m in width.
While the strike extent is currently unknown, the fault has been mapped at surface to over 2.5km and hosts several other gold occurrences such as the Commodore mine about 600m north of Reids Ridge.
Formerly known as the Rose Marie Mine, the Reids Ridge Gold Mine produced about 1,812oz of gold grading 19.77g/t from underground workings intermittently from 1913 through to present day.
Underground workings extend from surface to about 150m depth. Between 2003 and 2005 the existing headframe shaft and ladder were refurbished allowing for access to hoist approximately 400t of mined ore to the surface and provide drill access.
As part of this program, TNT will also test the Mt Laws prospect that is along strike both to the east and west of previously completed drilling.
Mineralisation at Mt Laws is associated with a contact between a thin BIF unit and the surrounding dolerite.
Drilling by a previous operator returned results such as 4m at 3.48g/t gold and 2m at 3.32g/t gold.
