The Halls Creek Project includes the Nicolsons Mine, (45 km south west of Halls Creek) and a pipeline of exploration and development prospects located east of Halls Creek in the Kimberley Region of Western Australia.
Halls Creek continued to produce gold throughout the 2023, however operations were placed on care and maintenance in June 2023 as the much larger Norseman project has come on line.
Pantoro announced the identification of a large PGE bearing system at Halls Creek in late 2021. Results to date clearly demonstrate that the Lamboo PGE-Nickel discovery is of a significant size and potential. Pantoro will continue with both drilling and mineralogical studies during the next year with a view to demonstrate the commercial viability of the project.
Pantoro is continuing to advance negotiations with multiple parties for divestment of the Halls Creek asset. |

Summary:
Gold mineralization in the Nicolson’s Find area is structurally controlled within the 400 m wide NNE trending dextral strike slip Nicolson’s Find Shear Zone (NFSZ) and is hosted within folded and metamorphosed turbiditic greywackes, felsic volcaniclastics, mafic volcanics and laminated siltstones and mudstones. This zone forms part of a regional NE-trending strike slip fault system developed across the Halls Creek Orogen (HCO).
The NFSZ comprises a NNE-trending anastomosing system of brittle-ductile shears, characterised by a predominantly dextral sense of movement. The principal shear structures trend NNE to N-S and are linked by NW, and to a lesser extent, by NE shears. Individual shears extend up to 500m along strike and overprint the earlier folding and penetrative cleavage of the HCO.
The overall geometry of the system is characterized by right step-overs and bends/jogs in the shear traces, reflecting refraction of the shears about the granite contact. Within this system, the NW- striking shears are interpreted as compressional structures and the NE striking shears formed within extensional windows. Mineralization is primarily focussed along NNE trending anastomosing systems of NNE-SSW, NW-SE and NE-SW oriented shears and splays. The NNE shears dip moderately to the east, while the NW set dips moderately to steeply to the NE. Both sets display variations in dip, with flattening and steepening which result in a complex pattern of shear inter ........
Summary:
Underground mining continued until operations were placed on care and maintenance in June 2023. The majority of work was undertaken at Wagtail. Remnant mining continued at Nicolsons for the majority of the year, with a combination of long hole stoping and handheld methods.
At Wagtail, mining in the Rowdies, REV and Wagon lodes continued to the 1930 mRL, while two levels were developed and mined in Wagtail South. Availability of ore in the Wagtail South area, combined with ongoing depth extensions at Rowdies present opportunities for recommencement of underground mining in the future.
Halls Creek has several open pit prospects available to be mined as stand-alone operations or in conjunction with ongoing underground operations. The project also has a large and highly prospective exploration tenure which will continue to be advanced in the future.
