Frewena Projects
The company’s Frewena suite of projects is considered highly prospective for Tier-1 Iron Ore Copper-Gold (IOCG) and also SEDEX style (lead, zinc, copper, silver) mineralisation.
Inca Minerals holds approximately 3,930km2 of granted tenure and exploration licences in the emerging, yet underexplored, East Tennant IOCG-SEDEX province of the Northern Territory. The tenements include:
- Frewena Fable (EL 31974 and EL 32287);
- Frewena East (EL 32795, EL 32857 and EL 33258);
- Frewena Far East (EL 33282); and,
- Frewena Frontier (EL 32688, EL 32689, and EL 32690).
Frewena Fable, Frewena East and Frewena Far East are part of a joint venture between Inca (90%), MRG Resources Pty Ltd (5%) and Dr Jonathan West (5%), with Frewena Frontier Inca (90%) and MRG Resources Pty Ltd (10%). The Company was an early mover in identifying the potential of this new mineral province.
Initial targeting of the Frewena Group areas – undertaken prior to the release of GA’s data – was guided by historical exploration data and coincident radiometric and topography anomolies that indicated granitic intrusions within the regionally mapped sedimentary sequence. Initial project exploration included detailed review of regional geophysical datasets, field reconnaissance, interrogation of ASTER data and detailed AMAGRAD surveying.
In 2020, the NTGS and GA recently released world-class geological and geophysical data over the area between Tennant Creek and the Queensland border. These data sets have resulted in a rare opportunity to peer beneath cover to reveal the mineral potential of that which lies below. The newly recognised East Tennant Province is considered highly prospective for IOCG type deposits, as well as for orogenic gold and SEDEX base metal systems.
The company has also undertaken, with funding support from the NT Governments’ GDC program, extensive aerial and ground geophysical surveys which have identified multiple strong targets on all of the Frewena tenements. Interpretation of both the broad regional and the company’s geophysical data sets has identified a number of large prospective gravity and magnetic features.
The Frewena Projects represent compelling IOCG and SEDEX targets and have demonstrated a number of key attributes that support this view – with this theory now strongly backed by drill results from the company’s initial reconnaissance drill program in 2022 – 2023. With over 6,000 metres drilled to date at the Roadhouse, Jumping Spider, Mount Lamb SW, Mount Lamb NE and Alpaca Hill targets, all:
- holes have been successful;
- targets have been validated; and
- IOCG and/or SEDEX indicators have been recorded at all targets drilled.
The geophysical and drilling exploration work undertaken to date strongly validates the IOCG and SEDEX models for the area. The company’s belief is that major hydrothermal systems occur with the Project areas.
Project areas sit comfortably in the middle of the highest priority modelled IOCG potential area within the new East Tennant province and boast a number of high priority exploration targets.
The Frewena Project is considered to represent a once in a generation exploration opportunity.
