Carlton Hill Project

Newly staked ground in the northern Bonaparte Basin targeting carbonate-hosted base metals

North Kimberley, Western Australia
50km North of Kununurra
Staked 2025

Project Overview

Mantle has recently staked new exploration tenure at Carlton Hill, approximately 50 km north of Kununurra in the northern Bonaparte Basin. This tenure lies along the same structural trend as the Sorby Hills Pb-Zn-Ag system, which hosts a large carbonate-hosted base-metal deposit approximately 35 km to the west.

The region hosts the significant Sorby Hills Deposit, containing 47.3 Mt at 3.1% lead, 0.4% zinc and 35 g/t silver. Mantle's Carlton Hill ground extends along the same Carlton Shelf structural trend, providing exposure to underexplored carbonate-hosted lead-zinc-silver systems with copper potential.

The Carlton Hill area is considered underexplored, with limited modern geophysics or systematic mapping completed historically. Mantle will undertake compilation of open-file datasets and reconnaissance-scale geological assessment to determine the most prospective stratigraphic and structural positions for follow-up.

Geological Context

Mantle's Carlton Hill ground extends along the same Carlton Shelf structural trend recognised by North Limited (1994), providing exposure to underexplored carbonate-hosted lead-zinc-silver systems with additional copper potential.

The proximity to the Sorby Hills deposit, located just 35 km to the west and containing significant base metal mineralisation, demonstrates the fertility of this geological corridor and validates the exploration model.

Future Programs

Mantle will undertake data compilation, remote sensing, and reconnaissance mapping as an initial phase of exploration to identify the most prospective targets.

This systematic approach will help define priority areas for follow-up work, with the objective of identifying drill-ready targets across this highly prospective but underexplored tenure.
