Highlights
- A ground EM survey in the vicinity of the EM1 anomaly, defined by the earlier TEMPEST airborne survey, has confirmed the presence of a significant basement conductor (named the Bristol anomaly).
- The Bristol EM anomaly is present over a strike length of 1200m with a more highly conductive core of extending over 550 metres strike, and the depth to the top is estimated to be 50-100m.
- Infill EM lines have confirmed there is a jog or fault along the conductive trend, and this may be important for defining a dilatational zone through which hydrothermal fluids could have transported mineralisation.
- The Bristol anomaly is coincident with weakly anomalous nickel and copper surface geochemistry. The anomaly may be due to mineralised (nickel-copper) sulphides however it should be noted that the anomaly may also be due to barren sulphides such as pyrite and/or pyrrhotite or sulphide bearing black/carbonaceous shales.
- The anomaly is blind to surface and drilling is required to ascertain the source of the anomaly.
- Modeling of the ground EM data is in progress to define drill hole locations for the next phase of exploratiion and evaluation.
