Gateway Mining Limited (ASX: GML) has defines several high order anomalies from a recently completed soil geochemical sampling programme covering the southern half of the Montague Granodiorite System within its 100%- owned Gidgee Gold Project in WA.
A total of 1124 samples were collected on a nominal 200m x 50m grid.
Managing Director, Peter Langworthy, saidthis programme has been successful in defining several high order anomalies, both corresponding and extending from areas of historic gold mining activity, as well as a significant anomaly across the granodiorite body and into the host mafic volcanic sequence.
A major anomaly over 3.8km in length- named Crosswind – has been defined corresponding to a northeast trending zone of intense structural deformation that crosscuts the granodiorite body and into the mafic volcanics to the west.
Mr Langworthy said these structures appear to play an intimate role in the location of several historic prospects and along the western edge of the granodiorite system. Historic drilling in this area outside of the historic workings, largely consists of shallow RAB drilling. In light of recent compilation work undertaken by Gateway, it is considered that this shallow drilling is largely ineffective in testing bedrock gold mineralisation at the Gidgee Gold Project.
Extensive anomalism has also been defined along the western contact of the Montague Granodiorite, corresponding to a line of historic gold workings known as the Dandelion Workings. This anomaly corresponds to an interpreted splay off the thrust fault that hosts mineralisation in the Caledonian pit to the north.
Several of the anomalies are open to the north along the edge of this programme, into areas of significant interest for potential gold mineralisation. As a result of the success of this programme, the coverage of soil geochemical sampling is due to be extended to the north and west, to provide for complete coverage of the current areas being targeted by Gateway’s exploration focus.
Mr Langworthy said a significantly expanded soil geochemical sampling programme has been designed, with field work due to commence the week of May 18, 2020.
He said this expanded programme is expected to significantly enhance the definition of several targets identified by Gateway through its systematic data compilation and interpretation process.
Following this next sampling programme, it is expected that drill testing of several high-priority targets will commence in the second half of June.
