‘Highly compelling’: Strickland uncovers second high grade gold structure at Millrose

Strickland continues to receive thick, high grade gold assay results highlighting the potential of its Millrose project in WA’s world-renowned Yandal Greenstone Belt.

Importantly, results such as 5m grading 8.7 grams per tonne (g/t) gold from 89m within a broader 19m intersection at 2.9g/t gold from 76m (MRRC317) and 13m at 2.1g/t gold from 83m (MRRC313) at Millrose West were returned from an entirely separate, sub-parallel structure to the main Millrose shear structure.

This structure is hosted within an entirely distinct stratigraphic package, highlighting the potential for a secondary, high-grade system analogous to Millrose.

Results within the main system were also significant for Strickland Metals (ASX:STK) with Millrose Central returning peak assays of 14m at 3g/t gold from 79m within a 32m zone at 1.8g/t gold from 66m (MRRC393D) and 12m at 3.3g/t gold from 158m (MRRC389D).

Peak assays of 5m at 8g/t gold from 101m (MRRC417) and 6m at 6.4g/t gold from 56m (MRRC420) were returned from Millrose North while Wanamaker returned a 6.7m zone grading 4.6g/t gold from 130.3m.

The results represent the balance of assays due from the company’s 2022 drill campaign and will be included in an updated resource to be released this year.

New structure “highly-compelling”

“Our 2022 drilling campaign at Millrose has been enormously successful in delineating new zones of mineralisation, discovering significantly more oxide gold closer to surface, and achieving major extensions to the existing primary mineralised envelopes,” chief executive officer Andrew Bray said.

“Of particular excitement towards the end of the drilling campaign, Strickland drilled further to the west of the main Millrose structure and intersected a secondary shear structure, hosted within an entirely separate stratigraphic package.

“Historically this area had only been subject to shallow aircore drilling, with little understanding of the structural controls on mineralisation, and drilling having been too shallow to have intersected the structure.”

He added that the results returned to date have confirmed the potential for a secondary, high-grade system at Millrose West which remains entirely untested along strike and at depth.

This is potentially very significant as the structure – located 200m west of the main Millrose structure – is traceable in geophysics datasets over about 5km, just a little longer than the 3.2km length of the main Millrose structure.

“From the work completed by Strickland, NE-trending fault structures are critical to the localisation of high-grade gold mineralisation along the Millrose Shear (and indeed, across the broader Yilgarn Craton),” Bray explained.

“Given the recent discovery of this ‘fertile’ sub-parallel Millrose West Structure, there are many locations along strike where NE trending fault structures transect it, which to date have not been drill tested.

“Overall, this new western shear structure represents a highly compelling exploration target. Most significantly, it demonstrates the potential for a secondary ‘look-a-like’ Millrose analogue to the West.”

Planning is currently underway for drilling in 2023.
