Induced Polarisation key to success in Anova’s hunt for gold at Big Springs
Link copied to
IP has emerged as a robust approach towards exploration targeting at Anova’s Big Springs gold project in Nevada.
This follows results from IP surveying in late June to early July confirming that parts of the Big Springs gold deposit are anomalously chargeable – indicating that it is a valid and appropriate method for the ongoing search for sulphide mineralisation across the wider licence area.
Anova Metals (ASX:AWV) noted that IP data for all three lines acquired is of excellent quality and shows strong chargeability anomalies associated with Brien’s fault; one of two controlling northeast structures bounding the core of the Big Springs deposit.
It will incorporate the resistivity and chargeability models into ongoing data analysis in 3D with testing of robust targets expected to form part of its 2023 drill program.
Additional IP surveying this season is under consideration subject to crew availability.
The IP survey consisted of 3 lines totalling 5.9 line kilometres that were oriented east-west and spaced about 1km apart.
Besides confirming that it could be used to identify drill targets, the survey also returned interesting and unexplained anomalies which have been flagged for further consideration and possible drilling.
Anova noted that the extensive chargeable zone between Crusher Zone and Beadles Creek on line 2 is of particular interest and is not currently understood.
It added that while the near surface mineralisation does not exhibit a strong response, the chargeable material at depth could be a more carbonaceous unit or disseminated sulphides.
