Thomson Resources Ltd. Strong Ground EM Anomaly Near Byrock
![Thomson Resources Ltd. Strong Ground EM Anomaly Near Byrock](https://www.minenportal.de/media/goldseiten-news.jpg)
Highlights:
- Ground EM follow up of an airborne VTEM anomaly generates a robust conductor.
- Modelling generates a steeply dipping conductor not tested by historic drilling
- Drill testing of Tritton-type massive sulphide target is planned
The strong VTEM anomaly at Wilga Downs was confirmed by the ground based survey, with the new information adding higher resolution, greater depth penetration and new definition of the conductive response. The anomaly and its geological setting are consistent with a Tritton-type volcanogenic massive sulphide (VMS) deposit: Tritton occurs in the same type and age rocks 100km to the southeast.
The moving loop EM ground survey provided higher resolution information to greater depths. The results from the new survey define the conductor more effectively owing to its greater depth penetration. In addition we now have better definition on its orientation which is thought to be striking NE-SW and dipping southeast. Independent modelling has fitted a NE-SW striking and southeast dipping conductor plate to the data, significantly different to initial VTEM modelling, and consistent with a peak magnetic response. The target conductor has not been tested by historic holes in the vicinity, namely 71W1 and 78WD01.
The Wilga Downs prospect on EL 8136, lies 35km west of Byrock in an area believed to have potential for Tritton-type copper deposits. Tritton was discovered by ground EM (SIROTEM) and was also marked by a magnetic anomaly. The Wilga Downs area features several distinct magnetic anomalies, one of which has been drilled with two holes: one in 1971 by AMAX (71W1) and one in 1978 by CRAE (78WD01). Both holes returned anomalous copper and zinc. Of the several EM conductive anomalies identified in the area by the VTEM survey, the most prominent is coincident with this magnetic anomaly. The conductor occurs between the previous drilling (Figure 2, see link below). The anomaly is strong and persists from mid to late-response times suggesting a highly conductive zone possibly associated with sulphides.
A drill test is being prepared and may occur at the same time as the upcoming second phase of drilling at the Bygoo tin project near Ardlethan. Modelling work continues on this and other VTEM anomalies in the Byrock area that were surveyed in early July.
