TRINEX MINERALS LIMITED Todd River Resources Limited announced that initial Fixed loop electromagnetic (FLTEM) surveying over a number of previously announced SkyTEM Airborne EM conductors has confirmed a significant bedrock conductor at the Trix Prospect in the northern part of its 100% owned Nerramyne Project located approximately 130 kilometres north east of Geraldton in the Murchison region of Western Australia. In addition, results from an initial Reverse Circulation (RC) drilling program have returned encouraging Platinum and Palladium anomalism over a broad intersection at the Chandler Prospect in the south of the Nerramyne Project. Follow up RC drilling targeting both the conductor at Trix and PGE anomalism at Chandler is planned to commence late in September, together with a regional aircore program targeting a number of intrusions throughout the project area.
A targeted FLTEM survey was completed over a number of previously interpreted conductors generated from the SkyTEM survey completed earlier this year. The FLTEM survey confirmed a robust bedrock conductor at the Trix prospect. The conductor was recorded on two lines which both show a well defined profile with a response on all components that is consistent with a bedrock conductor source.
Decays are clearly exponential and have a 25-50ms exponential time-constant. The modelled plate position is robust and has a size of ~100 x 100 metres and a conductance of 2700- 3300 Siemens. RC drilling at Trix was carried out to better understand the geology in the area.
Subsequently, interpretation of the FLTEM data has shown that this drilling was subparallel to the modelled orientation of the plate and missed the conductor. FLTEM work over other SkyTEM conductors has caused the initial interpreted conductors to be downgraded due to a variety of reasons. These include original SkyTEM conductors being interpreted to have been caused by super-paramagnetic effects potentially derived from magnetite in channel gravels or profiles and decay rates simply not being consistent with bedrock conductors.
