New drilling campaign to focus compelling VMS targets at Rover project

AEM and MLTEM results over channel 15 and TSC targets

TSC Limited is pleased to report the recently-completed moving loop transient electromagnetic (MLTEM) survey confirmed that all eight airborne electromagnetic (AEM) anomalies selected represent excellent bedrock conductors. The MLTEM survey follows on from the successful AEM survey undertaken by TSC in February 2020, which identified 27 anomalies at the Rover project . Notably, the vast majority of the AEM anomalies identified are situated along the 20km long prospective gold strike that is part of the Maynard Hills greenstone belt (picture below).

  • Results of a targeted moving loop TEM (MLTEM) survey over eight previously identified AEM anomalies have confirmed very strong bedrock conductors consistent with volcanic massive sulphide (VMS) mineralisation 
  • Due to the strength of the results, these eight bedrock conductors – which are located along the Maynard Hills greenstone belt – have been classified as compelling targets
  • Notably, two of the bedrock conductors are along strike from Creasy 2, where the following recently-assayed intercept confirmed a VMS signature: 
    • 24m @ 1,825ppm Zn from surface, grades up to 3,020ppm Zn in a 3m composite sample & 6m @ 2,210ppm from 33m (19RVRC016)
  • Pre-approvals have already been secured and preparations are now underway for RC drill testing of these VMS targets to commence shortly  
  • The RC drill rig used in previous campaigns remains on-site and is available to recommence drilling for TSC 

All eight surveyed lines confirmed the presence of strongly conductive, discrete bedrock conductors that are typically expected from VMS-style mineralisation. Moreover, the model geometries range from sub-vertical to moderately west dipping, which is consistent with the area’s underlying geology. Encouragingly, all conductors are generally shallow, ranging from sub-cropping to 90m deep.

CEO Ian Warland of TSC Limited commented: “Securing pre-approvals to progress TSC’s drilling campaign has proved to be prudent, since the MLTEM survey results have exceeded our expectations. In short, the conductive responses from all eight AEM anomalies surveyed is not only consistent with VMS-style mineralisation, but qualifies them all as outstanding targets. We look forward to commencing the next round of drilling at Rover to focus on these targets imminently and to keeping shareholders apprised of developments as they unfold over the next few weeks.”
