Strickland has no shortage of targets at its Iroquois project in Western Australia’s Earaheedy Basin after identifying multiple new areas of elevated copper-lead-zinc anomalism.

Its large-scale soil sampling found the new anomalies due west of both the Iroquois discovery and the Malecite prospect.

This is especially important given that previous work has indicated that copper in soil appears to be an accurate market of potential feeder structures, which are believed to generate the primary zinc-lead mineralisation discovered at Iroquois, in the area.

Strickland Metals (ASX:STK) has also rescheduled the Iroquois native title heritage survey – revised to include drill testing of these new base metal anomalies – to start on 24 October due to local cultural reasons.

“The promising story at Iroquois is continuing to develop with the delineation of multiple new targets. Regional reconnaissance work and geophysical surveys have occurred in recent months with a view to locating promising areas for follow up drill testing,” chief executive officer Andrew Bray said.

“Importantly, these prospects all appear to be controlled by major basin regional structures and potential cross-cutting fault structures. The company is of the view these areas could represent new feeder structures for the primary zinc-lead mineralisation.

“The chloritic siltstone unit (the geological unit which sits above the Iroquois Dolomite) has been detected in outcrop on the ground. This is very promising as it suggests the system is continuing to the north-west from Iroquois towards the tenement boundary with Rumble Resources.

“The discovery at Iroquois appears to be a Mississippi Valley Type (MVT) zinc-lead style of mineralisation. These types of systems typically generate a cluster of deposits, so multiple new prospects related to regional and cross-cutting structures is exactly what we were hoping to define out of this program.”

New targets

The new targets were identified by a wider, more extensive soil program aimed at highlighting additional fertile structures that could connect the initial Iroquois discovery.

Subsequent ground truthing of these anomalies has found that much of this area is under shallow cover though isolated patches of exposed chloritic siltstone suggests that there are repetitions in the sequence of stratigraphy, moving from east to west.

This further enhances the geological model of this being a regional graben structure, with the ‘feeder structures’ marking the original basin architecture.
