Further high-grade gold oxide assays from Strickland Metals Ltd reveal new zones at Millrose
Strickland Metals Ltd (ASX:STK) has commissioned additional shallow high-grade gold deposits from drilling at its flagship 100% owned Millrose project on Western Australia’s Yandal greenstone belt, including the discovery of a new zone of mineralization which improves the economic potential of the project.
Initial wide-spaced drilling north of Millrose yielded a new gold oxide discovery that extends mineralization at least 350 meters to the north, which remains open to the west. Additional drilling will be undertaken to test extensions of mineralization to the north and west.
Trial highlights include:
- 37 meters at 1.6 g/t gold from 58 meters, including 9 meters at 5.6 g/t from 86 meters including 3 meters at 12.3 g/t from 86 meters;
- 53 meters at 1.1 g/t from 44 meters including 13 meters at 3.3 g/t from 84 meters;
- 12 meters at 4.9 g/t from 64 meters including 4 meters at 13.6 g/t from 68 meters;
- 4 meters at 2.3 g/t from 40 meters; and
- 4 meters at 1.3 g/t from 69 meters.
The company will undertake infill drilling to incorporate the new results into an updated mineral resource in 2023.
Strickland Managing Director Andrew Bray said: “We are very pleased to provide further analysis from our flagship Millrose Gold project. These excellent results continue to demonstrate Millrose’s large-scale potential, with Strickland’s systematic exploration programs to date having significantly increased the mineralization footprint.
“There is a significant and emerging story around the intersection of increasingly impressive shallow oxidized gold results. Drilling along strike of the current mineral resource intersected a consistent zone over 350 meters to the north , with mineralization remaining fully open to the north and west (upstream of today’s results) New lenses have also been discovered directly above Millrose.
“None of these results are included in the current mineral resource model.
Gold oxide lenses
Drilling also intersected new shallow gold oxide lenses above the existing resource, with results such as:
- 3 meters at 14.8 g/t gold from 8 meters;
- 7 meters at 1 g/t from 4 meters;
- 11 meters at 2.4 g/t from 58 meters including 2 meters at 8.6 g/t from 65 meters;
- 2 meters at 1.2 g/t from 43 meters – extends the current wireframe 20 meters to the west; and
- 5 meters at 3.4 g/t from 82 meters.
Millrose North Drilling
Resource drilling also successfully mapped the northern extent of the north-dipping high-grade Millrose North mineralized zone, with results such as:
- 28 meters at 2.0 g/t gold from 101 meters;
- 21 meters at 2.0 g/t from 168 meters;
- 27.7 meters at 1.8 g/t from 234.3 meters including 10.7 meters at 3.1 g/t;
- 25.8 meters at 1.6 g/t from 244 meters including 8.8 meters at 2.0 g/t;
- 9.1 meters at 2.6 g/t from 178.8 meters;
- 10 meters at 1.6 g/t from 149 meters;
- 24 meters at 0.8 g/t from 145 meters;
- 11 meters at 1.1 g/t from 165 meters;
- 13 meters at 1.2 g/t from 187 meters; and
- 20 meters at 0.6 g/t from 203 meters.

Exploration in progress
“The discovery of additional shallow oxide mineralization (above the existing fresh rock mineralization) can potentially be of critical importance in mine development, allowing a deeper pit to be driven in mining scenarios. optimization,” Bray said.
“The company has also identified another discovery of 400 meters of known oxide gold mineralization from historic drilling at Millrose Central, which is also not included in the current mineral resources. A number of RC holes have been drilled in this zone, with analyzes expected at the end of September/beginning of October.
“We also successfully drilled three deeper diamond holes below the current mineral resource, following the very impressive intersection in MRDD008 (8.1 meters at 14.6 g/t gold from 215 meters, in a wider mineralized envelope of 95 meters at 2.2 g/t gold from 176.5 meters) This drilling suggests strong potential for further high-grade extensions at depth.
“Finally, the two RC rigs are systematically testing the shear structure to the north and south of the main Millrose domain. Fencelines of short RC holes on 200 meter outings are drilled to accurately map the shear structure This program is expected to be completed in September 2022, at which time the company will return to the most promising areas for further follow-up drilling.
