Gold hits continue to unravel at pace with results demonstrating the upside in terms of width and grade, while also contributing to a strong economic case around the development of Millrose.

Key highlights from reverse circulation drilling include 5m at 11.5g/t gold from 68m, 65m at 4.4g/t gold from 95m inkling 3m at 20.2g/t gold and 3m at 33.5g/t gold.

Strickland Metals (ASX:STK) managing director Andrew Bray says the oxide results continue to surprise and equally exciting is that mineralisation is just beginning to show up with drilling intersecting the start of another potential zone in hole MRRC130.

Here an intersection of 8m at 4g/t gold from 104m was returned.

Gold mineralisation is also open to the south, with the southernmost hole drilled to date returning 21m at 1g/t gold from 86m in hole MRRC128.

Drill rigs will continue testing shear structure

“These sets of results demonstrate the large potential scale of the Millrose system, particularly in light of the fact we have only drilled approximately one quarter of the mineralised shear structure to date,” Bray says.

“The drill rigs will continue systematically testing the shear structure to the north and south to fully delineate the size and scale of the Millrose gold system, before returning to undertake closer spaced infill drilling.”

Multiple new high-grade zones

Mineralisation at Millrose is now understood to be controlled by two sets of shear structures, with NE-SW shearing cross-cutting and offsetting the pre-dated North-South shear zone, creating high grade zones of dilation.

The north-south shear is denoted by pervasive eastward-dipping foliation, associated silica-sulphide flooding, and the development of a mylonite unit.

STK says the north-trending shear forms the bulk of the wide, high-grade deposit at Millrose North and the overall > 3 km mineralised trend.

To assist with understanding the main controls on gold mineralisation, Strickland undertook micro-XRF scanning of core samples across Millrose to map the relationship between gold, alteration, structure, and geochemistry.

Several samples from diamond holes MRDD002 and MRDD008 (Millrose North) and several samples from MRDD011 were analysed as part of this process.

Preliminary results show that gold is present in multiple styles, spanning both shearing events:

  • Quartz-carbonate and chlorite-carbonate veining with the same orientation as the NE-SW cross-cutting shears;
  • Pervasive carbonate and sodic alteration; and
  • Gold does not appear to be associated with any of the sulphides, confirming the non-refractory nature of the ore
