Inca reports ‘significant’ visible copper mineralisation at MaCauley Creek

Inca Minerals Limited (ASX : ICG) has announced that it has encountered significant visible skarn-style copper mineralisation at multiple locations during a recent surface mapping program at its MaCauley Project in northern Queensland, with the discovery ‘substantially upgrading’ project potential.

The field trip was conducted to examine the Mount Brown and Carraway North prospect areas in the northern parts of the project, which were recently identified through an independent review of and remodelling historical geophysical data.

It also explored other potential areas that had been identified in the central and southern areas of the project.

Inca reports that mapping has revealed several mineralised skarn occurrences as well as a gossanous orphyry (the weathered remnants of sulphide mineralisation). Accordingly, the project has been elevated in terms of its potential to host a tier-1 scale copper discovery.

Promising results from key prospects

The company has reported findings from several prospects within MaCauley:

  • Mount Brown: Visible skarn-style copper mineralisation, gossanous limestone and gossanous porphyry
  • Wallaroo: Visible skarn-style copper mineralisation extending over 850m strike length
  • Copper Cliffs (renamed from Carraway North): Visible copper mineralisation extending over 550m strike length, varying in width from 5m to 15m

Up next at MaCauley

Inca plans to continue in-house analysis of the field trip results while awaiting analysis results from rock chip samples, with assays due in September.

The company plans to carry out a 3,000-line kilometre AMAGRAD survey across the northern third and the southeast corner of MaCauley, to assist in refining northern prospects and Mt Podge. The survey is expected to commence in the coming weeks, unless COVID delays travel.

It is also thought that follow-up ground geophysics – principally IP surveying may be necessary to complete detailed drill targeting studies, with additional activities including soil sampling, ground magnetic surveying and prospect scale mapping.
