- The high-resolution airborne survey being undertaken by TEM will cover two areas -- Meleya and War West
- The company says extremely high-resolution data generated would complement the current datasets
- Tempest's Yalgoo region holding spans over 1,000 sq.km, with the company having 100% ownership of the tenements
Australian-listed Tempest Minerals (ASX: TEM) -- a mineral explorer into precious, base and energy metals -- has announced the commencement of an electromagnetic (EM) survey at its Yalgoo tenements (fully owned). The high-resolution airborne survey is being undertaken across the central portion of the tenements. Tempest informs that the activity -- which would enable high-resolution geophysical data -- would complement the existing datasets.
This latest EM survey at the company’s Yalgoo asset would cover two project areas -- Meleya and War West. The company expects to generate several new exploration targets by undertaking this exercise.
Shares jump over 8%
Triggered by the update, TEM shares gained over 8% to trade at AU$0.013 at the time of writing on 21 June 2023.
Electromagnetic survey targeting sulphide mineralisation
Notably, the fully owned highly prospective tenements of TEM in Western Australia’s Yalgoo region span over four project areas including the above two and Messenger and Euro. Tempest considers its landholding in the Yalgoo region, which is witnessing active exploration, as the flagship within its diverse portfolio.
The ASX-listed explorer has engaged the services of geophysical contracting company NRG, which TEM states holds specialisation in gathering ultra-high resolution airborne data. NRG is using ultra high-resolution electromagnetic loop ‘XCite’ system -- which is custom built and mounted on the helicopter -- to perform the exercise.
TEM also informs that NRG will cover nearly 300 lines of 200m spacing. This will be approximately a total of 2,000 km of line survey measurements. Large percentage of two project areas -- Meleya and War West -- will be covered by the EM survey.
The company expects to achieve details on new exploration and drill targets, alongside verification of existing exploration targets and increased resolution to the underlying geology through this survey.
It is also stated that the previous work at the Orion target, including magnetic modelling and downhole electromagnetic surveys, will be "progressively integrated" with the new EM survey dataset. This will help to calibrate and inform the survey modelling.
Tempest Minerals informs that the EM survey will likely be completed by the end of this month. Next steps will include preliminary modelling and targets (expected next month), alongside continuation of region-wide progression of exploration targets including numerous planned drilling activities.
