MaCauley Creek Porphyry Project

The MaCauley Creek Project is considered prospective for Cu-Au porphyry mineralisation.

The Project is located approximately 100km west of Townsville in Queensland. It consists of two granted exploration permits (EPM 27124 and EPM 27163) covering some 359km2 and it lies within the Townsville-Mornington Island porphyry belt.

MaCauley Creek was acquired through the execution of a formal agreement with MRG Resources in 2019. MaCauley Creek has a history of mining in the early 1990’s and intermittent past exploration. A number of strong geochemical and geophysical targets have been identified at the Project.

While high-grade and widespread mineralisation has been reported in historical small-scale miners and past explorers, the area remained overlooked for large scale mineral systems such as Cu-Au porphyry systems. Known Cu-Au-Mo±(Pb+Zn) mineralisation at Mac Creek covers a very large area (3km x 2.5km). Importantly, this mineralisation occurs in various intrusive granites. Known porphyry dykes and porphyry style alteration contained within this 3kmx2.5km area. The detailed magnetic data collected are considered strong support of this theory with two large intrusions beneath and adjacent to historical mine sites and exploration prospects, as well as additional magnetic features observed.

Inca has progressed this Project significantly since picking it up in 2019, with mapping and sampling confirming the porphyry hallmark of this Project. In addition, geophysical surveying has identified a number of strong targets, some of which have been drilled and others still to be drilled. A priority drill target is the Central area, where there is a line of historical copper workings underlain by a 1km long chargeability anomaly.
