Cattle Creek EPM 27912, Palmerville Station

Location

The Cattle Creek EPM 27912 is situated on the eastern side of Palmerville Station, within a region well known for its historical and modern mining significance. The area lies in proximity to the Cannibal Creek Mine — a historically important gold-tin-tungsten mining centre that operated from the 1960s and remains a recognised polymetallic reference point for the region. 

Access to the tenement is reliable and well established. A regularly maintained graded road—shared between Palmerville Station’s campgrounds and two nearby hard-rock mining operations—provides direct entry into the project area. This access route connects to Whites Creek Road, which continues to the Mulligan Highway, approximately 44 km south of the Palmerville Station campgrounds driveway, enabling effective transport of personnel, equipment, and services.

The tenement also benefits from its proximity to the active Mount Carbine Tungsten Mine (operated by EQ Resources), located to the east. This critical-minerals operation underscores the long-term potential for tungsten and associated metals in the region, and positions Cattle Creek within a recognised polymetallic corridor.

Processing and Results

The Cattle Creek airborne dataset was carefully processed, gridded, and imaged to produce a comprehensive suite of high-quality geophysical products. A total of ten interpretive maps (Maps 01–10) have been generated and are supplied in PDF format for review. These include magnetic intensity, vertical derivatives, tilt derivatives, radiometric ternaries, structural interpretations, and other value-enhancing filters.

Complementary digital GIS-ready images have also been produced in GeoTIFF format to support integration into geological modelling, GIS platforms, and field planning workflows. File naming conventions for all digital outputs have been standardised for ease of use and direct import into exploration datasets.

3D Inversion Modelling

To further interpret the magnetic responses identified across the Cattle Creek survey area, unconstrained 3D magnetic inversion modelling was undertaken using MGinv3D developed by Scientific Computing and Applications. This advanced modelling approach provides insight into the geometry, depth extent, and relative magnetic susceptibility of subsurface structures that may host mineralisation.

The inversion utilised a model cell size of 50 m × 50 m, with vertical cell thicknesses of 25 m down to a depth of 1,000 m, increasing progressively to depths exceeding 3,000 m. High-resolution topographic data derived from the Cattle Creek airborne survey was incorporated to ensure accurate modelling relative to surface terrain.

As the inversion was unconstrained, no prior geological or susceptibility controls were imposed. This allows the algorithm to allocate any positive magnetic susceptibility value to each model cell, providing a true data-driven visualisation of subsurface magnetic domains.

The results are presented as depth slices, 3D iso-shells, and a full XYZ block model, offering multiple perspectives for evaluating potential targets. Figure 2 illustrates representative depth slices draped beneath topography, while Figure 3 displays selected iso-shells in 3D perspective.

Delivered Inversion Model Products

The following datasets have been produced and supplied as part of the Cattle Creek 3D modelling package:

• Model_XYZ
  A complete 3D inversion block model in XYZ format, including centroid coordinates (E, N, RL), cell dimensions (DX, DY, DZ), and modelled magnetic susceptibility values (SI × 10⁻⁶).

• Model_Shells
  3D iso-shells extracted from the inversion model at defined susceptibility thresholds. Each file name reflects the susceptibility value (SI × 10⁻⁶) enclosed by the shell. (Provided in DXF format.)

• Model_Images
  High-resolution depth slice images draped below topography, allowing visual correlation between magnetic domains and surface features. (Provided in GeoTIFF format.)
