- A 750m mineralised structure has been defined west of the existing Dusk til Dawn mineral resource
- Structure runs parallel with the known 109,000oz Dusk til Dawn gold resource
- Additional drilling to be carried out by Strickland Metals
Special Report: Cashed-up gold explorer Strickland Metals has a bunch of prospects at its Yandal gold project – and recently expanded a drill program west of the Horse Well and Dusk til Dawn which uncovered a consistent 750m-long primary mineralised structure.
After selling its Millrose gold project to Northern Star Resources (ASX:NST) for $61 million in July last year, Strickland Metals (ASX:STK) has been hard at it with the drill bit across a number of prospects, including Horse Well, Dusk til Dawn and Marwari.
Recent successes include a 31m intersection grading at 5.6g/t gold from 70m to the end-of-hole at HWAC1472 and a 5m at whopping 28g/t gold as part of a 19-hole program at the Marwari prospect.
Significant mineralisation identified
In November last year, Strickland expanded its AC drill program away from Horse Well, where the bulk of the drilling had already occurred.
One of these areas was the ground to the west of the existing 109,000oz Dusk til Dawn gold resource, about 50km from Horse Well.
AC results have highlighted a significant 750m parallel mineralised structure open at depth and along strike immediately west from the existing Dusk til Dawn resource.
Previous RC drilling back in January 2022 found the gold mineralisation is closely associated with intense potassic (biotite) and sulphide (pyrite) alteration that changes to chlorite (+ magnetite) alteration away from the main gold-bearing lode.
This same alteration style (potassic core and chlorite halo) was intersected across the recently identified parallel western shear zone, with many of the holes ending in gold mineralisation.
STK says this demonstrates the potential for multiple stacked and parallel mineralised lodes which would significantly increase the resource base, with both Dusk til Dawn and the new mineralised structure remaining open down dip and plunge.
Additional drilling is expected to enhance the understanding of the thickness and grade distribution and will form part of a larger drill program across the Horse Well project area.
Improved understanding of mineralised controls
STK managing director Andrew Bray says the area was poorly understood, in particular the geometry and potential controls on mineralisation.
“These AC results have now successfully defined a coherent 750m target corridor and given the interpreted orientation of mineralisation, the position of the primary structure is yet to be tested in fresh rock,” Bray says.
“The gold mineralisation remains entirely open down dip and down plunge and a particular area of high priority for future drilling is the interpreted area where the two sub-parallel shear zones are predicted to intersect.
“These results are a good reminder of the tremendous potential our Yandal gold project offers.
“While most of the drilling last year occurred at Horse Well (where significant new mineralisation was discovered and requires follow-up drilling), the mineralisation referred to in this announcement is over 20km away.
“The greenstone belt remains virtually unexplored for the entirety of the ground between these prospect areas, with only very patchy historic programs having occurred.
“Separately, RC drilling has recommenced on-site at Rabbit Well after significant rain throughout the project area.
“Drilling is focused on mapping the overall geological, alteration and pathfinder geochemical model to vector in on the primary source of the previously intersected oxide base metal mineralisation.”
Further assays are expected to be received and released in the coming fortnight.
